HVAC (heating, ventilation, and air conditioning) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. Refrigeration is sometimes added to the field’s abbreviation as HVAC&R or HVACR.
The history of auto A/C dates back to 1933 when a company in New York City first offered installation of air conditioning for cars. However, The Packard Motor Car Company was the first automobile manufacturer to offer an air conditioning unit into its cars, beginning in 1939. Since then, loads of advancements have been made to enhance performance of this inevitable system in modern cars.
The air conditioning system in cars is comprised of a compressor, condenser, expansion valve and evaporator. Refrigerant is compressed in the compressor and turns into a hot gas. In the condenser, this hot gas is cooled to a liquid state and travels to the expansion valve. As the Freon goes through the expansion valve it returns to a low-pressure gas and rapidly cools in the evaporator. A fan blows over the evaporator and cools the air that eventually blows out the vents.
