Predictive maintenance relies on continuous monitoring and analysis of system data to anticipate failures before they occur. For mobile home HVAC systems, this means collecting data from various sensors that track temperature fluctuations, humidity levels, compressor cycles, fan speeds, and more. By analyzing this data over time, patterns can be detected that might indicate potential issues such as refrigerant leaks, motor wear, or duct obstructions.


The benefits of predictive maintenance are manifold. Firstly, it enhances comfort by reducing unexpected breakdowns that could leave residents sweltering in summer heat or shivering during winter nights. Since mobile homes are often located in areas where extreme weather conditions can be more pronounced due to less insulation and protection from outdoor elements, maintaining a reliable HVAC system is crucial.


Furthermore, predictive maintenance contributes significantly to the reliability of these systems. Regularly updated data provides insights into component health and helps schedule timely interventions before minor issues escalate into major problems requiring costly repairs or replacements. This proactive approach not only extends the lifespan of HVAC components but also ensures energy efficiency by keeping the system running at optimal performance levels.


Moreover, the integration of smart technology with HVAC systems has made data collection more accessible than ever. Mobile homeowners can now benefit from smart thermostats and connected devices that provide real-time updates on system performance directly on their smartphones or tablets. This empowers users with knowledge about their system's health and helps them make informed decisions regarding its operation.


In conclusion, evaluating system data for predictive maintenance plays a vital role in enhancing the comfort and reliability of HVAC systems in mobile homes. By leveraging technology to predict potential failures before they happen, homeowners can enjoy a consistently comfortable indoor environment while ensuring their heating and cooling equipment operates efficiently for years to come. As mobile home living continues to grow in popularity as an affordable housing option, investing in advanced HVAC solutions will remain a priority for both manufacturers and residents alike.

Predictive maintenance has emerged as a transformative approach in various industries, allowing companies to anticipate equipment failures and optimize maintenance schedules. The essence of predictive maintenance lies in evaluating system data to forecast potential breakdowns before they occur. While the theory behind this approach is compelling, its real-world application is best understood through case studies and examples of successful implementation.


One notable example comes from the aviation industry, where predictive maintenance has revolutionized aircraft operations.

By predicting component failures early on, Siemens Gamesa ensures that turbines maintain optimal output without interruption-key for maximizing renewable energy contributions.


The railway industry also provides an exemplary case of successful implementation of predictive maintenance techniques. The Swiss Federal Railways (SBB) employs sophisticated diagnostic systems that assess track conditions and rolling stock components in real-time. Through continuous monitoring and analysis of infrastructure data, SBB can prioritize necessary repairs efficiently and avoid costly service interruptions while maintaining high safety standards for passengers.


These case studies highlight several common elements critical to successful predictive maintenance implementation: robust data collection methods, advanced analytical tools capable of handling large datasets effectively; skilled personnel adept at interpreting insights; strong organizational commitment towards fostering innovation; collaboration between departments such as IT & operations teams who work together seamlessly throughout project lifecycle stages-from initial planning phases through execution phases-all contributing factors ensuring seamless integration into existing workflows without disruption caused by unforeseen technical challenges arising during deployment phase(s).


In conclusion-and supported by these diverse examples across multiple industries-the value proposition offered by implementing effective systems designed specifically around evaluating system data for predictive purposes becomes increasingly clear-cut: reduced operational costs via minimized unplanned downtimes coupled alongside improved asset utilization rates ultimately translate into enhanced competitive advantages benefiting organizations willing embrace forward-thinking approaches toward asset management practices today!

Predictive maintenance has emerged as a transformative approach for managing HVAC systems in mobile homes, offering significant benefits through the evaluation of system data. By leveraging advanced analytics and real-time monitoring, predictive maintenance allows homeowners and technicians to anticipate system failures before they occur, thus enhancing reliability and efficiency.


One real-world example of predictive maintenance's impact can be seen in a community of mobile homes located in Florida, where extreme weather conditions often place heavy demands on HVAC systems. In this community, residents faced frequent interruptions in their air conditioning services during peak summer months due to unexpected breakdowns. To mitigate these issues, a local service provider implemented a predictive maintenance program using IoT sensors embedded within the HVAC units. These sensors continuously collected data on various parameters such as temperature fluctuations, energy consumption patterns, and component wear.


The collected data was analyzed using machine learning algorithms that identified potential failure points based on historical trends and anomalies. For instance, one common issue detected early was the gradual degradation of compressor coils-a critical component influencing cooling efficiency. By receiving alerts well in advance of an actual failure, technicians could schedule timely interventions to clean or replace coils without disrupting service to the residents.


Another illustrative case is from a mobile home park in Arizona where energy costs were spiraling due to inefficient HVAC operation. Here, predictive maintenance technology helped optimize performance by analyzing fan speeds and thermostat settings relative to outdoor temperatures. The system provided actionable insights into improving energy consumption strategies such as adjusting airflow during off-peak hours or suggesting optimal thermostat settings to maximize cooling while minimizing power usage.


The financial implications of predictive maintenance are equally noteworthy. In both examples mentioned above, residents experienced reduced repair costs as emergent issues were addressed before escalating into major repairs or complete system overhauls. Additionally, enhanced system longevity translated into postponed replacement expenses-a significant consideration for cost-conscious mobile home owners.


Furthermore, predictive maintenance contributed positively to environmental sustainability by reducing energy waste and lowering carbon footprints associated with excessive electricity use in malfunctioning systems. This aspect not only aligns with global environmental goals but also offers tangible benefits for communities striving towards sustainable living practices.


In conclusion, the application of predictive maintenance for HVAC systems in mobile homes exemplifies how evaluating system data can lead to substantial improvements in operational reliability and cost-efficiency. Real-world implementations demonstrate that by anticipating potential failures through advanced diagnostics and analytics tools, both homeowners and technicians can enjoy uninterrupted comfort while optimizing resource utilization-a compelling proposition for modern living scenarios characterized by increasing technical complexity and economic constraints.

Evaluating system data for predictive maintenance has become a cornerstone in the realm of modern industrial operations, offering the promise of increased efficiency and reduced downtime. As industries increasingly turn to data-driven approaches, numerous lessons have emerged from various implementations that provide valuable insights for future endeavors.


One of the most significant lessons learned is the importance of data quality and integrity. Predictive maintenance relies heavily on accurate and timely data to forecast potential equipment failures. Inadequate or inaccurate data can lead to false predictions, which may either result in unnecessary maintenance actions or, worse, unexpected equipment breakdowns. Therefore, ensuring high-quality data collection through well-calibrated sensors and robust data management systems is imperative.


Another critical lesson is the necessity of integrating domain expertise with advanced analytics. While machine learning algorithms and statistical models play a crucial role in analyzing system data, they must be complemented by human expertise to interpret results effectively. Domain experts bring invaluable insights into understanding equipment behavior and contextualizing analytical findings within operational realities. This synergy between technology and human knowledge enhances decision-making processes.


Furthermore, scalability emerges as a key consideration in predictive maintenance implementations. Systems should be designed with scalability in mind to accommodate growing volumes of data as more assets are monitored over time. Cloud-based solutions offer flexible storage and computational resources that can dynamically scale according to needs, making them ideal for large-scale deployments.


The importance of cross-departmental collaboration cannot be overstated either.

Moreover, one must not overlook the significance of continuous improvement and adaptation. The landscape of technology evolves rapidly; hence, predictive maintenance strategies should be periodically reviewed and updated to incorporate emerging technologies such as IoT advancements or new analytical techniques. Continuous feedback loops allow organizations to learn from past experiences and refine their approaches iteratively.


Lastly, there is an inherent need for change management when implementing predictive maintenance systems. Resistance may arise from employees accustomed to traditional preventive or reactive maintenance practices who may feel threatened by new technologies automating parts of their roles. Addressing these concerns through training programs that emphasize skill enhancement rather than replacement can facilitate smoother transitions while maximizing workforce engagement.


In conclusion, evaluating system data for predictive maintenance presents both opportunities for operational excellence along with challenges requiring careful attention during implementation phases. By prioritizing high-quality datasets backed by expert interpretation alongside scalable solutions underpinned by collaborative efforts across departments-organizations stand poised not only achieve improved asset reliability but also unlock newfound efficiencies within their operations landscape fostering sustainable growth paths ahead.

Predictive maintenance technology has been revolutionizing various industries by enabling more efficient and cost-effective operations, and the HVAC (Heating, Ventilation, and Air Conditioning) systems sector is no exception. As we look towards future trends in this field, evaluating system data for predictive maintenance emerges as a crucial component. This essay explores the evolving landscape of data evaluation techniques that are propelling predictive maintenance in HVAC systems to new heights.


At the core of predictive maintenance lies the ability to anticipate equipment failures before they occur, thereby reducing downtime and minimizing repair costs. Traditionally, HVAC systems relied on reactive or scheduled maintenance approaches. However, these methods often resulted in either unnecessary service interventions or unexpected breakdowns. The advent of predictive maintenance technology aims to overcome these limitations by leveraging real-time data from HVAC systems.


One of the most significant future trends is the integration of advanced sensors and IoT (Internet of Things) devices within HVAC units. These devices continuously monitor various parameters such as temperature, pressure, humidity, and energy consumption. By collecting vast amounts of data from different parts of an HVAC system, operators can gain deeper insights into its operational health. This sensor-based approach enables early detection of anomalies, allowing for timely intervention before a minor issue escalates into a major malfunction.


Machine learning algorithms play an increasingly vital role in evaluating system data for predictive maintenance. These algorithms analyze historical and real-time data to identify patterns indicative of potential failures. Over time, machine learning models become more accurate in predicting when a particular component might fail based on subtle changes in performance metrics. This shift from rule-based diagnostics to AI-driven analytics significantly enhances the precision and reliability of maintenance predictions.


Another emerging trend is the use of digital twins-virtual replicas of physical HVAC systems-that simulate their behavior under various conditions. By integrating real-time data into these digital models, technicians can run simulations to forecast how different factors might impact system performance over time. Digital twins facilitate scenario analysis without disrupting actual operations, providing valuable insights that inform proactive maintenance strategies.


Cloud computing also plays a pivotal role in advancing predictive maintenance for HVAC systems by offering scalable storage solutions for vast datasets generated by IoT devices.

This accessibility ensures informed decision-making regardless of geographical constraints.


Moreover, augmented reality (AR) technologies are beginning to find applications within predictive maintenance practices by enhancing technician training programs through immersive experiences that replicate real-world scenarios involving complex repairs or adjustments needed during servicing sessions onsite at client premises across diverse locations worldwide.


In conclusion, future trends in evaluating system data for predictive maintenance technology within HVAC systems highlight an exciting convergence between cutting-edge technologies like IoT sensors combined with powerful computing capabilities offered via cloud services alongside artificial intelligence-driven analytical frameworks designed specifically towards optimizing operational efficiency levels while reducing overall lifecycle costs associated with maintaining critical infrastructure components essential towards ensuring optimal indoor climate control environments remain consistently maintained year-round across varying weather patterns globally experienced today more than ever before due largely thanks due largely thanks due largely thanks due largely thanks technological advancements seen throughout recent years alone!

In the rapidly evolving world of technology, the heating, ventilation, and air conditioning (HVAC) industry is experiencing a transformative shift driven by emerging technologies and innovative approaches. One of the most promising developments in this sector is the use of predictive maintenance through advanced data evaluation. This novel approach is shaping the future of HVAC system maintenance by providing substantial improvements in efficiency, cost-effectiveness, and overall reliability.


Predictive maintenance is an innovative strategy that utilizes data-driven insights to anticipate potential failures before they occur. Unlike traditional reactive maintenance practices-which address issues only after they arise-predictive maintenance leverages real-time data from HVAC systems to forecast when components are likely to fail or require service. This proactive method not only minimizes downtime but also extends the lifespan of equipment by ensuring timely interventions.


At the heart of predictive maintenance lies sophisticated data analytics powered by cutting-edge technologies such as artificial intelligence (AI) and machine learning (ML). These technologies enable HVAC systems to collect vast amounts of operational data from sensors embedded throughout the equipment. Parameters such as temperature fluctuations, vibration levels, energy consumption, and airflow rates are continuously monitored and analyzed to detect anomalies or trends indicative of impending problems.


Machine learning algorithms play a crucial role in this process by identifying patterns within historical data and applying them to current system performance. By doing so, these algorithms can accurately predict when a specific part may fail based on similar past occurrences. This capability allows facility managers and technicians to schedule repairs at optimal times, reducing unexpected breakdowns and minimizing disruptions.


Moreover, IoT (Internet of Things) connectivity enhances predictive maintenance by facilitating seamless communication between HVAC components and centralized monitoring systems. IoT-enabled devices can provide real-time alerts and diagnostics remotely, allowing technicians to assess situations without being physically present. This connectivity not only saves time but also provides valuable insights into system health across multiple locations simultaneously.


The benefits of predictive maintenance extend beyond operational efficiency; they also have significant financial implications. By shifting from a break-fix model to a preventive approach, businesses can reduce repair costs associated with emergency services and unplanned replacements. Additionally, optimized performance leads to improved energy efficiency-a critical factor given rising utility costs-and contributes positively towards sustainability goals by lowering carbon footprints.


However, implementing predictive maintenance requires overcoming certain challenges as well. Data security concerns must be addressed due to increased reliance on connected devices that transmit sensitive information over networks susceptible to cyber threats. Moreover, investing in infrastructure capable of supporting robust analytics platforms may pose initial financial constraints for smaller enterprises reluctant about adopting new technologies amidst budgetary limitations.


Despite these hurdles though-the integration between emerging technologies like AI/ML coupled with IoT innovations makes it clear that evaluating system data for predictive purposes represents an indispensable advancement within modern-day HVAC management strategies poised toward achieving unprecedented levels success moving forward into tomorrow's digitally interconnected landscape where intelligent solutions reign supreme above all else!

Evaluating system data for predictive maintenance holds significant promise for enhancing living conditions in mobile homes. As mobile homes often include mechanical systems such as HVAC, plumbing, and electrical networks that are susceptible to wear and tear, leveraging predictive maintenance can revolutionize the way these systems are managed.


Predictive maintenance relies on the collection and analysis of data from various components within a home's infrastructure. By deploying sensors and utilizing Internet of Things (IoT) technology, it becomes feasible to monitor the real-time performance of essential systems in mobile homes. This continuous stream of data allows for the early detection of potential issues before they escalate into serious problems, thus ensuring more reliable functionality.


The primary benefit of this approach is the prevention of unexpected failures that can drastically impact living conditions. For instance, imagine an air conditioning unit failing during a heatwave or a water heater breaking down in winter. Predictive maintenance mitigates such inconvenient scenarios by identifying irregular patterns or anomalies in system performance that typically precede breakdowns. Maintenance teams can then address these concerns proactively, thereby preventing discomfort and ensuring uninterrupted service delivery.


Moreover, implementing predictive maintenance can lead to cost savings for mobile home residents. Regularly scheduled or reactive repairs often incur higher costs due to emergency call-outs and extensive damage rectification efforts. In contrast, addressing issues at their nascent stage through predictive measures tends to be less costly since it involves minor adjustments rather than full-scale replacements or overhauls.


In addition to economic advantages, there is an environmental aspect to consider as well. Efficiently maintained systems generally consume less energy and resources compared to those that operate sub-optimally due to neglect or late intervention. This results in reduced utility bills for homeowners and decreases overall environmental impact-an increasingly critical consideration in today's world.


Furthermore, predictive maintenance enhances safety within mobile homes by reducing risks associated with system failures, such as electrical fires from faulty wiring or water damage from leaking plumbing fixtures. Consistent monitoring ensures that any hazardous conditions are identified swiftly and dealt with appropriately.


For residents who may not possess technical expertise regarding their home's mechanical systems, predictive maintenance offers peace of mind knowing that their living environment is being continuously assessed by sophisticated technology capable of preempting malfunctions.


Overall, evaluating system data for predictive maintenance represents a forward-thinking approach that aligns with modern technological advancements while directly benefiting mobile home dwellers through improved reliability, cost efficiency, environmental responsibility, enhanced safety features, and greater comfort in daily life experiences. As this field continues to evolve with further innovations in sensor technology and data analysis techniques, its potential impact on living conditions stands poised to grow even more substantial over time.

 

There are various types of air conditioners. Popular examples include: Window-mounted air conditioner (Suriname, 1955); Ceiling-mounted cassette air conditioner (China, 2023); Wall-mounted air conditioner (Japan, 2020); Ceiling-mounted console (Also called ceiling suspended) air conditioner (China, 2023); and portable air conditioner (Vatican City, 2018).

 

Air conditioning, often abbreviated as A/C (US) or air con (UK),[1] is the process of removing heat from an enclosed space to achieve a more comfortable interior temperature (sometimes referred to as 'comfort cooling') and in some cases also strictly controlling the humidity of internal air. Air conditioning can be achieved using a mechanical 'air conditioner' or by other methods, including passive cooling and ventilative cooling.[2][3] Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC).[4] Heat pumps are similar in many ways to air conditioners, but use a reversing valve to allow them both to heat and to cool an enclosed space.[5]

Air conditioners, which typically use vapor-compression refrigeration, range in size from small units used in vehicles or single rooms to massive units that can cool large buildings.[6] Air source heat pumps, which can be used for heating as well as cooling, are becoming increasingly common in cooler climates.

Air conditioners can reduce mortality rates due to higher temperature.[7] According to the International Energy Agency (IEA) 1.6 billion air conditioning units were used globally in 2016.[8] The United Nations called for the technology to be made more sustainable to mitigate climate change and for the use of alternatives, like passive cooling, evaporative cooling, selective shading, windcatchers, and better thermal insulation.

History

[edit]

Air conditioning dates back to prehistory.[9] Double-walled living quarters, with a gap between the two walls to encourage air flow, were found in the ancient city of Hamoukar, in modern Syria.[10] Ancient Egyptian buildings also used a wide variety of passive air-conditioning techniques.[11] These became widespread from the Iberian Peninsula through North Africa, the Middle East, and Northern India.[12]

Passive techniques remained widespread until the 20th century when they fell out of fashion and were replaced by powered air conditioning. Using information from engineering studies of traditional buildings, passive techniques are being revived and modified for 21st-century architectural designs.[13][12]

Air conditioners allow the building's indoor environment to remain relatively constant, largely independent of changes in external weather conditions and internal heat loads. They also enable deep plan buildings to be created and have allowed people to live comfortably in hotter parts of the world.[14]

Development

[edit]

Preceding discoveries

[edit]

In 1558, Giambattista della Porta described a method of chilling ice to temperatures far below its freezing point by mixing it with potassium nitrate (then called "nitre") in his popular science book Natural Magic.[15][16][17] In 1620, Cornelis Drebbel demonstrated "Turning Summer into Winter" for James I of England, chilling part of the Great Hall of Westminster Abbey with an apparatus of troughs and vats.[18] Drebbel's contemporary Francis Bacon, like della Porta a believer in science communication, may not have been present at the demonstration, but in a book published later the same year, he described it as "experiment of artificial freezing" and said that "Nitre (or rather its spirit) is very cold, and hence nitre or salt when added to snow or ice intensifies the cold of the latter, the nitre by adding to its cold, but the salt by supplying activity to the cold of the snow."[15]

In 1758, Benjamin Franklin and John Hadley, a chemistry professor at the University of Cambridge, conducted experiments applying the principle of evaporation as a means to cool an object rapidly. Franklin and Hadley confirmed that the evaporation of highly volatile liquids (such as alcohol and ether) could be used to drive down the temperature of an object past the freezing point of water. They experimented with the bulb of a mercury-in-glass thermometer as their object. They used a bellows to speed up the evaporation. They lowered the temperature of the thermometer bulb down to −14 °C (7 °F) while the ambient temperature was 18 °C (64 °F). Franklin noted that soon after they passed the freezing point of water 0 °C (32 °F), a thin film of ice formed on the surface of the thermometer's bulb and that the ice mass was about 6 mm (14 in) thick when they stopped the experiment upon reaching −14 °C (7 °F). Franklin concluded: "From this experiment, one may see the possibility of freezing a man to death on a warm summer's day."[19]

The 19th century included many developments in compression technology. In 1820, English scientist and inventor Michael Faraday discovered that compressing and liquefying ammonia could chill air when the liquefied ammonia was allowed to evaporate.[20] In 1842, Florida physician John Gorrie used compressor technology to create ice, which he used to cool air for his patients in his hospital in Apalachicola, Florida. He hoped to eventually use his ice-making machine to regulate the temperature of buildings.[20][21] He envisioned centralized air conditioning that could cool entire cities. Gorrie was granted a patent in 1851,[22] but following the death of his main backer, he was not able to realize his invention.[23] In 1851, James Harrison created the first mechanical ice-making machine in Geelong, Australia, and was granted a patent for an ether vapor-compression refrigeration system in 1855 that produced three tons of ice per day.[24] In 1860, Harrison established a second ice company. He later entered the debate over competing against the American advantage of ice-refrigerated beef sales to the United Kingdom.[24]

First devices

[edit]
Willis Carrier, who is credited with building the first modern electrical air conditioning unit

Electricity made the development of effective units possible. In 1901, American inventor Willis H. Carrier built what is considered the first modern electrical air conditioning unit.[25][26][27][28] In 1902, he installed his first air-conditioning system, in the Sackett-Wilhelms Lithographing & Publishing Company in Brooklyn, New York.[29] His invention controlled both the temperature and humidity, which helped maintain consistent paper dimensions and ink alignment at the printing plant. Later, together with six other employees, Carrier formed The Carrier Air Conditioning Company of America, a business that in 2020 employed 53,000 people and was valued at $18.6 billion.[30][31]

In 1906, Stuart W. Cramer of Charlotte, North Carolina, was exploring ways to add moisture to the air in his textile mill. Cramer coined the term "air conditioning" in a patent claim which he filed that year, where he suggested that air conditioning was analogous to "water conditioning", then a well-known process for making textiles easier to process.[32] He combined moisture with ventilation to "condition" and change the air in the factories; thus, controlling the humidity that is necessary in textile plants. Willis Carrier adopted the term and incorporated it into the name of his company.[33]

Domestic air conditioning soon took off. In 1914, the first domestic air conditioning was installed in Minneapolis in the home of Charles Gilbert Gates. It is, however, possible that the considerable device (c. 2.1 m × 1.8 m × 6.1 m; 7 ft × 6 ft × 20 ft) was never used, as the house remained uninhabited[20] (Gates had already died in October 1913.)

In 1931, H.H. Schultz and J.Q. Sherman developed what would become the most common type of individual room air conditioner: one designed to sit on a window ledge. The units went on sale in 1932 at US$10,000 to $50,000 (the equivalent of $200,000 to $1,100,000 in 2023.)[20] A year later, the first air conditioning systems for cars were offered for sale.[34] Chrysler Motors introduced the first practical semi-portable air conditioning unit in 1935,[35] and Packard became the first automobile manufacturer to offer an air conditioning unit in its cars in 1939.[36]

Further development

[edit]

Innovations in the latter half of the 20th century allowed more ubiquitous air conditioner use. In 1945, Robert Sherman of Lynn, Massachusetts, invented a portable, in-window air conditioner that cooled, heated, humidified, dehumidified, and filtered the air.[37] The first inverter air conditioners were released in 1980–1981.[38][39]

In 1954, Ned Cole, a 1939 architecture graduate from the University of Texas at Austin, developed the first experimental "suburb" with inbuilt air conditioning in each house. 22 homes were developed on a flat, treeless track in northwest Austin, Texas, and the community was christened the 'Austin Air-Conditioned Village.' The residents were subjected to a year-long study of the effects of air conditioning led by the nation’s premier air conditioning companies, builders, and social scientists. In addition, researchers from UT’s Health Service and Psychology Department studied the effects on the "artificially cooled humans." One of the more amusing discoveries was that each family reported being troubled with scorpions, the leading theory being that scorpions sought cool, shady places. Other reported changes in lifestyle were that mothers baked more, families ate heavier foods, and they were more apt to choose hot drinks.[40][41]

Air conditioner adoption tends to increase above around $10,000 annual household income in warmer areas.[42] Global GDP growth explains around 85% of increased air condition adoption by 2050, while the remaining 15% can be explained by climate change.[42]

As of 2016 an estimated 1.6 billion air conditioning units were used worldwide, with over half of them in China and USA, and a total cooling capacity of 11,675 gigawatts.[8][43] The International Energy Agency predicted in 2018 that the number of air conditioning units would grow to around 4 billion units by 2050 and that the total cooling capacity would grow to around 23,000 GW, with the biggest increases in India and China.[8] Between 1995 and 2004, the proportion of urban households in China with air conditioners increased from 8% to 70%.[44] As of 2015, nearly 100 million homes, or about 87% of US households, had air conditioning systems.[45] In 2019, it was estimated that 90% of new single-family homes constructed in the US included air conditioning (ranging from 99% in the South to 62% in the West).[46][47]

Operation

[edit]

Operating principles

[edit]
A simple stylized diagram of the refrigeration cycle: 1) condensing coil, 2) expansion valve, 3) evaporator coil, 4) compressor

Cooling in traditional air conditioner systems is accomplished using the vapor-compression cycle, which uses a refrigerant's forced circulation and phase change between gas and liquid to transfer heat.[48][49] The vapor-compression cycle can occur within a unitary, or packaged piece of equipment; or within a chiller that is connected to terminal cooling equipment (such as a fan coil unit in an air handler) on its evaporator side and heat rejection equipment such as a cooling tower on its condenser side. An air source heat pump shares many components with an air conditioning system, but includes a reversing valve, which allows the unit to be used to heat as well as cool a space.[50]

Air conditioning equipment will reduce the absolute humidity of the air processed by the system if the surface of the evaporator coil is significantly cooler than the dew point of the surrounding air. An air conditioner designed for an occupied space will typically achieve a 30% to 60% relative humidity in the occupied space.[51]

Most modern air-conditioning systems feature a dehumidification cycle during which the compressor runs. At the same time, the fan is slowed to reduce the evaporator temperature and condense more water. A dehumidifier uses the same refrigeration cycle but incorporates both the evaporator and the condenser into the same air path; the air first passes over the evaporator coil, where it is cooled[52] and dehumidified before passing over the condenser coil, where it is warmed again before it is released back into the room.[citation needed]

Free cooling can sometimes be selected when the external air is cooler than the internal air. Therefore, the compressor does not need to be used, resulting in high cooling efficiencies for these times. This may also be combined with seasonal thermal energy storage.[53]

Heating

[edit]

Some air conditioning systems can reverse the refrigeration cycle and act as an air source heat pump, thus heating instead of cooling the indoor environment. They are also commonly referred to as "reverse cycle air conditioners". The heat pump is significantly more energy-efficient than electric resistance heating, because it moves energy from air or groundwater to the heated space and the heat from purchased electrical energy. When the heat pump is in heating mode, the indoor evaporator coil switches roles and becomes the condenser coil, producing heat. The outdoor condenser unit also switches roles to serve as the evaporator and discharges cold air (colder than the ambient outdoor air).

Most air source heat pumps become less efficient in outdoor temperatures lower than 4 °C or 40 °F.[54] This is partly because ice forms on the outdoor unit's heat exchanger coil, which blocks air flow over the coil. To compensate for this, the heat pump system must temporarily switch back into the regular air conditioning mode to switch the outdoor evaporator coil back to the condenser coil, to heat up and defrost. Therefore, some heat pump systems will have electric resistance heating in the indoor air path that is activated only in this mode to compensate for the temporary indoor air cooling, which would otherwise be uncomfortable in the winter.

Newer models have improved cold-weather performance, with efficient heating capacity down to −14 °F (−26 °C).[55][54][56] However, there is always a chance that the humidity that condenses on the heat exchanger of the outdoor unit could freeze, even in models that have improved cold-weather performance, requiring a defrosting cycle to be performed.

The icing problem becomes much more severe with lower outdoor temperatures, so heat pumps are sometimes installed in tandem with a more conventional form of heating, such as an electrical heater, a natural gas, heating oil, or wood-burning fireplace or central heating, which is used instead of or in addition to the heat pump during harsher winter temperatures. In this case, the heat pump is used efficiently during milder temperatures, and the system is switched to the conventional heat source when the outdoor temperature is lower.

Performance

[edit]

The coefficient of performance (COP) of an air conditioning system is a ratio of useful heating or cooling provided to the work required.[57][58] Higher COPs equate to lower operating costs. The COP usually exceeds 1; however, the exact value is highly dependent on operating conditions, especially absolute temperature and relative temperature between sink and system, and is often graphed or averaged against expected conditions.[59] Air conditioner equipment power in the U.S. is often described in terms of "tons of refrigeration", with each approximately equal to the cooling power of one short ton (2,000 pounds (910 kg) of ice melting in a 24-hour period. The value is equal to 12,000 BTUIT per hour, or 3,517 watts.[60] Residential central air systems are usually from 1 to 5 tons (3.5 to 18 kW) in capacity.[citation needed]

The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER), which is defined by the Air Conditioning, Heating and Refrigeration Institute in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment.[61] A similar standard is the European seasonal energy efficiency ratio (ESEER).[citation needed]

Efficiency is strongly affected by the humidity of the air to be cooled. Dehumidifying the air before attempting to cool it can reduce subsequent cooling costs by as much as 90 percent. Thus, reducing dehumidifying costs can materially affect overall air conditioning costs.[62]

Control system

[edit]

Wireless remote control

[edit]
A wireless remote controller
The infrared transmitting LED on the remote
The infrared receiver on the air conditioner

This type of controller uses an infrared LED to relay commands from a remote control to the air conditioner. The output of the infrared LED (like that of any infrared remote) is invisible to the human eye because its wavelength is beyond the range of visible light (940 nm). This system is commonly used on mini-split air conditioners because it is simple and portable. Some window and ducted central air conditioners uses it as well.

Wired controller

[edit]
Several wired controllers (Indonesia, 2024)

A wired controller, also called a "wired thermostat," is a device that controls an air conditioner by switching heating or cooling on or off. It uses different sensors to measure temperatures and actuate control operations. Mechanical thermostats commonly use bimetallic strips, converting a temperature change into mechanical displacement, to actuate control of the air conditioner. Electronic thermostats, instead, use a thermistor or other semiconductor sensor, processing temperature change as electronic signals to control the air conditioner.

These controllers are usually used in hotel rooms because they are permanently installed into a wall and hard-wired directly into the air conditioner unit, eliminating the need for batteries.

Mini-split and multi-split systems

[edit]
Evaporator, indoor unit, or terminal, side of a ductless split-type air conditioner

Ductless systems (often mini-split, though there are now ducted mini-split) typically supply conditioned and heated air to a single or a few rooms of a building, without ducts and in a decentralized manner.[63] Multi-zone or multi-split systems are a common application of ductless systems and allow up to eight rooms (zones or locations) to be conditioned independently from each other, each with its indoor unit and simultaneously from a single outdoor unit.

The first mini-split system was sold in 1961 by Toshiba in Japan, and the first wall-mounted mini-split air conditioner was sold in 1968 in Japan by Mitsubishi Electric, where small home sizes motivated their development. The Mitsubishi model was the first air conditioner with a cross-flow fan.[64][65][66] In 1969, the first mini-split air conditioner was sold in the US.[67] Multi-zone ductless systems were invented by Daikin in 1973, and variable refrigerant flow systems (which can be thought of as larger multi-split systems) were also invented by Daikin in 1982. Both were first sold in Japan.[68] Variable refrigerant flow systems when compared with central plant cooling from an air handler, eliminate the need for large cool air ducts, air handlers, and chillers; instead cool refrigerant is transported through much smaller pipes to the indoor units in the spaces to be conditioned, thus allowing for less space above dropped ceilings and a lower structural impact, while also allowing for more individual and independent temperature control of spaces. The outdoor and indoor units can be spread across the building.[69] Variable refrigerant flow indoor units can also be turned off individually in unused spaces.[citation needed] The lower start-up power of VRF's DC inverter compressors and their inherent DC power requirements also allow VRF solar-powered heat pumps to be run using DC-providing solar panels.

Ducted central systems

[edit]

Split-system central air conditioners consist of two heat exchangers, an outside unit (the condenser) from which heat is rejected to the environment and an internal heat exchanger (the evaporator, or Fan Coil Unit, FCU) with the piped refrigerant being circulated between the two. The FCU is then connected to the spaces to be cooled by ventilation ducts.[70] Floor standing air conditioners are similar to this type of air conditioner but sit within spaces that need cooling.

Central plant cooling

[edit]

Large central cooling plants may use intermediate coolant such as chilled water pumped into air handlers or fan coil units near or in the spaces to be cooled which then duct or deliver cold air into the spaces to be conditioned, rather than ducting cold air directly to these spaces from the plant, which is not done due to the low density and heat capacity of air, which would require impractically large ducts. The chilled water is cooled by chillers in the plant, which uses a refrigeration cycle to cool water, often transferring its heat to the atmosphere even in liquid-cooled chillers through the use of cooling towers. Chillers may be air- or liquid-cooled.[71][72]

Portable units

[edit]

A portable system has an indoor unit on wheels connected to an outdoor unit via flexible pipes, similar to a permanently fixed installed unit (such as a ductless split air conditioner).

Hose systems, which can be monoblock or air-to-air, are vented to the outside via air ducts. The monoblock type collects the water in a bucket or tray and stops when full. The air-to-air type re-evaporates the water, discharges it through the ducted hose, and can run continuously. Many but not all portable units draw indoor air and expel it outdoors through a single duct, negatively impacting their overall cooling efficiency.

Many portable air conditioners come with heat as well as a dehumidification function.[73]

Window unit and packaged terminal

[edit]
Through-the-wall PTAC units, University Motor Inn, Philadelphia

The packaged terminal air conditioner (PTAC), through-the-wall, and window air conditioners are similar. These units are installed on a window frame or on a wall opening. The unit usually has an internal partition separating its indoor and outdoor sides, which contain the unit's condenser and evaporator, respectively. PTAC systems may be adapted to provide heating in cold weather, either directly by using an electric strip, gas, or other heaters, or by reversing the refrigerant flow to heat the interior and draw heat from the exterior air, converting the air conditioner into a heat pump. They may be installed in a wall opening with the help of a special sleeve on the wall and a custom grill that is flush with the wall and window air conditioners can also be installed in a window, but without a custom grill.[74]

Packaged air conditioner

[edit]

Packaged air conditioners (also known as self-contained units)[75][76] are central systems that integrate into a single housing all the components of a split central system, and deliver air, possibly through ducts, to the spaces to be cooled. Depending on their construction they may be outdoors or indoors, on roofs (rooftop units),[77][78] draw the air to be conditioned from inside or outside a building and be water or air-cooled. Often, outdoor units are air-cooled while indoor units are liquid-cooled using a cooling tower.[70][79][80][81][82][83]

Reciprocating

[edit]

This compressor consists of a crankcase, crankshaft, piston rod, piston, piston ring, cylinder head and valves. [citation needed]

Scroll

[edit]

This compressor uses two interleaving scrolls to compress the refrigerant.[84] it consists of one fixed and one orbiting scrolls. This type of compressor is more efficient because it has 70 percent less moving parts than a reciprocating compressor. [citation needed]

Screw

[edit]

This compressor use two very closely meshing spiral rotors to compress the gas. The gas enters at the suction side and moves through the threads as the screws rotate. The meshing rotors force the gas through the compressor, and the gas exits at the end of the screws. The working area is the inter-lobe volume between the male and female rotors. It is larger at the intake end, and decreases along the length of the rotors until the exhaust port. This change in volume is the compression. [citation needed]

Capacity modulation technologies

[edit]

There are several ways to modulate the cooling capacity in refrigeration or air conditioning and heating systems. The most common in air conditioning are: on-off cycling, hot gas bypass, use or not of liquid injection, manifold configurations of multiple compressors, mechanical modulation (also called digital), and inverter technology. [citation needed]

Hot gas bypass

[edit]

Hot gas bypass involves injecting a quantity of gas from discharge to the suction side. The compressor will keep operating at the same speed, but due to the bypass, the refrigerant mass flow circulating with the system is reduced, and thus the cooling capacity. This naturally causes the compressor to run uselessly during the periods when the bypass is operating. The turn down capacity varies between 0 and 100%.[85]

Manifold configurations

[edit]

Several compressors can be installed in the system to provide the peak cooling capacity. Each compressor can run or not in order to stage the cooling capacity of the unit. The turn down capacity is either 0/33/66 or 100% for a trio configuration and either 0/50 or 100% for a tandem.[citation needed]

Mechanically modulated compressor

[edit]

This internal mechanical capacity modulation is based on periodic compression process with a control valve, the two scroll set move apart stopping the compression for a given time period. This method varies refrigerant flow by changing the average time of compression, but not the actual speed of the motor. Despite an excellent turndown ratio – from 10 to 100% of the cooling capacity, mechanically modulated scrolls have high energy consumption as the motor continuously runs.[citation needed]

Variable-speed compressor

[edit]

This system uses a variable-frequency drive (also called an Inverter) to control the speed of the compressor. The refrigerant flow rate is changed by the change in the speed of the compressor. The turn down ratio depends on the system configuration and manufacturer. It modulates from 15 or 25% up to 100% at full capacity with a single inverter from 12 to 100% with a hybrid tandem. This method is the most efficient way to modulate an air conditioner's capacity. It is up to 58% more efficient than a fixed speed system.[citation needed]

Impact

[edit]

Health effects

[edit]

In hot weather, air conditioning can prevent heat stroke, dehydration due to excessive sweating, electrolyte imbalance, kidney failure, and other issues due to hyperthermia.[8][86] Heat waves are the most lethal type of weather phenomenon in the United States.[87][88] A 2020 study found that areas with lower use of air conditioning correlated with higher rates of heat-related mortality and hospitalizations.[89] The August 2003 France heatwave resulted in approximately 15,000 deaths, where 80% of the victims were over 75 years old. In response, the French government required all retirement homes to have at least one air-conditioned room at 25 °C (77 °F) per floor during heatwaves.[8]

Air conditioning (including filtration, humidification, cooling and disinfection) can be used to provide a clean, safe, hypoallergenic atmosphere in hospital operating rooms and other environments where proper atmosphere is critical to patient safety and well-being. It is sometimes recommended for home use by people with allergies, especially mold.[90][91] However, poorly maintained water cooling towers can promote the growth and spread of microorganisms such as Legionella pneumophila, the infectious agent responsible for Legionnaires' disease. As long as the cooling tower is kept clean (usually by means of a chlorine treatment), these health hazards can be avoided or reduced. The state of New York has codified requirements for registration, maintenance, and testing of cooling towers to protect against Legionella.[92]

Economic effects

[edit]

First designed to benefit targeted industries such as the press as well as large factories, the invention quickly spread to public agencies and administrations with studies with claims of increased productivity close to 24% in places equipped with air conditioning.[93]

Air conditioning caused various shifts in demography, notably that of the United States starting from the 1970s. In the US, the birth rate was lower in the spring than during other seasons until the 1970s but this difference then declined since then.[94] As of 2007, the Sun Belt contained 30% of the total US population while it was inhabited by 24% of Americans at the beginning of the 20th century.[95] Moreover, the summer mortality rate in the US, which had been higher in regions subject to a heat wave during the summer, also evened out.[7]

The spread of the use of air conditioning acts as a main driver for the growth of global demand of electricity.[96] According to a 2018 report from the International Energy Agency (IEA), it was revealed that the energy consumption for cooling in the United States, involving 328 million Americans, surpasses the combined energy consumption of 4.4 billion people in Africa, Latin America, the Middle East, and Asia (excluding China).[8] A 2020 survey found that an estimated 88% of all US households use AC, increasing to 93% when solely looking at homes built between 2010 and 2020.[97]

Environmental effects

[edit]

Space cooling including air conditioning accounted globally for 2021 terawatt-hours of energy usage in 2016 with around 99% in the form of electricity, according to a 2018 report on air-conditioning efficiency by the International Energy Agency.[8] The report predicts an increase of electricity usage due to space cooling to around 6200 TWh by 2050,[8][98] and that with the progress currently seen, greenhouse gas emissions attributable to space cooling will double: 1,135 million tons (2016) to 2,070 million tons.[8] There is some push to increase the energy efficiency of air conditioners. United Nations Environment Programme (UNEP) and the IEA found that if air conditioners could be twice as effective as now, 460 billion tons of GHG could be cut over 40 years.[99] The UNEP and IEA also recommended legislation to decrease the use of hydrofluorocarbons, better building insulation, and more sustainable temperature-controlled food supply chains going forward.[99]

Refrigerants have also caused and continue to cause serious environmental issues, including ozone depletion and climate change, as several countries have not yet ratified the Kigali Amendment to reduce the consumption and production of hydrofluorocarbons.[100] CFCs and HCFCs refrigerants such as R-12 and R-22, respectively, used within air conditioners have caused damage to the ozone layer,[101] and hydrofluorocarbon refrigerants such as R-410A and R-404A, which were designed to replace CFCs and HCFCs, are instead exacerbating climate change.[102] Both issues happen due to the venting of refrigerant to the atmosphere, such as during repairs. HFO refrigerants, used in some if not most new equipment, solve both issues with an ozone damage potential (ODP) of zero and a much lower global warming potential (GWP) in the single or double digits vs. the three or four digits of hydrofluorocarbons.[103]

Hydrofluorocarbons would have raised global temperatures by around 0.3–0.5 °C (0.5–0.9 °F) by 2100 without the Kigali Amendment. With the Kigali Amendment, the increase of global temperatures by 2100 due to hydrofluorocarbons is predicted to be around 0.06 °C (0.1 °F).[104]

Alternatives to continual air conditioning include passive cooling, passive solar cooling, natural ventilation, operating shades to reduce solar gain, using trees, architectural shades, windows (and using window coatings) to reduce solar gain.[citation needed]

Social effects

[edit]

Socioeconomic groups with a household income below around $10,000 tend to have a low air conditioning adoption,[42] which worsens heat-related mortality.[7] The lack of cooling can be hazardous, as areas with lower use of air conditioning correlate with higher rates of heat-related mortality and hospitalizations.[89] Premature mortality in NYC is projected to grow between 47% and 95% in 30 years, with lower-income and vulnerable populations most at risk.[89] Studies on the correlation between heat-related mortality and hospitalizations and living in low socioeconomic locations can be traced in Phoenix, Arizona,[105] Hong Kong,[106] China,[106] Japan,[107] and Italy.[108][109] Additionally, costs concerning health care can act as another barrier, as the lack of private health insurance during a 2009 heat wave in Australia, was associated with heat-related hospitalization.[109]

Disparities in socioeconomic status and access to air conditioning are connected by some to institutionalized racism, which leads to the association of specific marginalized communities with lower economic status, poorer health, residing in hotter neighborhoods, engaging in physically demanding labor, and experiencing limited access to cooling technologies such as air conditioning.[109] A study overlooking Chicago, Illinois, Detroit, and Michigan found that black households were half as likely to have central air conditioning units when compared to their white counterparts.[110] Especially in cities, Redlining creates heat islands, increasing temperatures in certain parts of the city.[109] This is due to materials heat-absorbing building materials and pavements and lack of vegetation and shade coverage.[111] There have been initiatives that provide cooling solutions to low-income communities, such as public cooling spaces.[8][111]

Other techniques

[edit]

Buildings designed with passive air conditioning are generally less expensive to construct and maintain than buildings with conventional HVAC systems with lower energy demands.[112] While tens of air changes per hour, and cooling of tens of degrees, can be achieved with passive methods, site-specific microclimate must be taken into account, complicating building design.[12]

Many techniques can be used to increase comfort and reduce the temperature in buildings. These include evaporative cooling, selective shading, wind, thermal convection, and heat storage.[113]

Passive ventilation

[edit]

Dogtrot houses are designed to maximise natural ventilation.
A roof turbine ventilator, colloquially known as a 'Whirly Bird' is an application of wind driven ventilation.

Passive ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems. It refers to the flow of external air to an indoor space as a result of pressure differences arising from natural forces.

There are two types of natural ventilation occurring in buildings: wind driven ventilation and buoyancy-driven ventilation. Wind driven ventilation arises from the different pressures created by wind around a building or structure, and openings being formed on the perimeter which then permit flow through the building. Buoyancy-driven ventilation occurs as a result of the directional buoyancy force that results from temperature differences between the interior and exterior.[114]

Since the internal heat gains which create temperature differences between the interior and exterior are created by natural processes, including the heat from people, and wind effects are variable, naturally ventilated buildings are sometimes called "breathing buildings".

Passive cooling

[edit]
 
A traditional Iranian solar cooling design using a wind tower

Passive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or no energy consumption.[115][116] This approach works either by preventing heat from entering the interior (heat gain prevention) or by removing heat from the building (natural cooling).[117]

Natural cooling utilizes on-site energy, available from the natural environment, combined with the architectural design of building components (e.g. building envelope), rather than mechanical systems to dissipate heat.[118] Therefore, natural cooling depends not only on the architectural design of the building but on how the site's natural resources are used as heat sinks (i.e. everything that absorbs or dissipates heat). Examples of on-site heat sinks are the upper atmosphere (night sky), the outdoor air (wind), and the earth/soil.

Passive cooling is an important tool for design of buildings for climate change adaptation – reducing dependency on energy-intensive air conditioning in warming environments.[119][120]
A pair of short windcatchers (malqaf) used in traditional architecture; wind is forced down on the windward side and leaves on the leeward side (cross-ventilation). In the absence of wind, the circulation can be driven with evaporative cooling in the inlet (which is also designed to catch dust). In the center, a shuksheika (roof lantern vent), used to shade the qa'a below while allowing hot air rise out of it (stack effect).[11]

Daytime radiative cooling

[edit]
Passive daytime radiative cooling (PDRC) surfaces are high in solar reflectance and heat emittance, cooling with zero energy use or pollution.[121]

Passive daytime radiative cooling (PDRC) surfaces reflect incoming solar radiation and heat back into outer space through the infrared window for cooling during the daytime. Daytime radiative cooling became possible with the ability to suppress solar heating using photonic structures, which emerged through a study by Raman et al. (2014).[122] PDRCs can come in a variety of forms, including paint coatings and films, that are designed to be high in solar reflectance and thermal emittance.[121][123]

PDRC applications on building roofs and envelopes have demonstrated significant decreases in energy consumption and costs.[123] In suburban single-family residential areas, PDRC application on roofs can potentially lower energy costs by 26% to 46%.[124] PDRCs are predicted to show a market size of ~$27 billion for indoor space cooling by 2025 and have undergone a surge in research and development since the 2010s.[125][126]

Fans

[edit]

Hand fans have existed since prehistory. Large human-powered fans built into buildings include the punkah.

The 2nd-century Chinese inventor Ding Huan of the Han dynasty invented a rotary fan for air conditioning, with seven wheels 3 m (10 ft) in diameter and manually powered by prisoners.[127]: 99, 151, 233  In 747, Emperor Xuanzong (r. 712–762) of the Tang dynasty (618–907) had the Cool Hall (Liang Dian 涼殿) built in the imperial palace, which the Tang Yulin describes as having water-powered fan wheels for air conditioning as well as rising jet streams of water from fountains. During the subsequent Song dynasty (960–1279), written sources mentioned the air conditioning rotary fan as even more widely used.[127]: 134, 151 

Thermal buffering

[edit]

In areas that are cold at night or in winter, heat storage is used. Heat may be stored in earth or masonry; air is drawn past the masonry to heat or cool it.[13]

In areas that are below freezing at night in winter, snow and ice can be collected and stored in ice houses for later use in cooling.[13] This technique is over 3,700 years old in the Middle East.[128] Harvesting outdoor ice during winter and transporting and storing for use in summer was practiced by wealthy Europeans in the early 1600s,[15] and became popular in Europe and the Americas towards the end of the 1600s.[129] This practice was replaced by mechanical compression-cycle icemakers.

Evaporative cooling

[edit]
An evaporative cooler

In dry, hot climates, the evaporative cooling effect may be used by placing water at the air intake, such that the draft draws air over water and then into the house. For this reason, it is sometimes said that the fountain, in the architecture of hot, arid climates, is like the fireplace in the architecture of cold climates.[11] Evaporative cooling also makes the air more humid, which can be beneficial in a dry desert climate.[130]

Evaporative coolers tend to feel as if they are not working during times of high humidity, when there is not much dry air with which the coolers can work to make the air as cool as possible for dwelling occupants. Unlike other types of air conditioners, evaporative coolers rely on the outside air to be channeled through cooler pads that cool the air before it reaches the inside of a house through its air duct system; this cooled outside air must be allowed to push the warmer air within the house out through an exhaust opening such as an open door or window.[131]
