Air Conditioning Units

Air conditioning units remove heat from the air through the use of a compressor, a condenser, an expansion valve, a thermostat and a series of motorized fans. Some units may be connected to air ducts or air handling equipment. Contrary to a widespread idea, air conditioning units do not add cold air to a space but instead removes heat from the existing air, making the space feel cooler.

Components of air conditioning units are usually made from stainless steel or aluminum. They vary in size; window units are small enough to fit between an open window and the ledge while industrial air conditioners are large enough to cool an entire plant or factory. Because they require electricity, air conditioning units may become costly if the space is not well-insulated or if the air is poorly circulated. Air conditioning units are usually placed in buildings where fans or natural breezes are inadequate because of temperature, air disturbance or pollution. Air conditioning systems often use air filters to maintain air quality and avoid spreading germs, pollutants or other unwanted irritants. They are used in residential buildings, industrial plants, factories, businesses, vehicles and many other places where cool air creates a more comfortable environment.


Air conditioning units have a thermostat that deforms in accordance with the current air temperature. When it reaches a predetermined temperature a sensor causes the unit to turn on until the thermostat measures the air temperature at a lower level.  A/C units, as they are frequently abbreviated, use a chemical called a refrigerant that can change quickly from a gas to a liquid. Freon is the most commonly used refrigerant. This chemical is contained inside coils within the body of the main unit. The compressor causes the refrigerant to change from a cool gas to a hot gas under pressure. As the gas runs through the coils, it condenses into a liquid as the heat dissipates. It is forced through the small opening of the expansion valve, which helps it evaporate back into a cold low-pressure gas. This gas runs through the coils to absorb heat from the air, cooling the space. Air conditioning units are available in a range of styles including portable, window, spot cooling, split air and more. Portable air conditioner units are moveable and can be easily transferred from space to space. Window units are mounted in an open window while spot cooling units are used to control localized heat sources. Split air unit systems have components inside and outside the facility.
