This is because the refrigerant will be subject to extreme cold and must be able to flow through the system.Ĭompressor: The compressor is the only mechanical component in the air conditioning system. In other words, it cannot turn into a solid, like water does, at temperatures near 32 degrees Fahrenheit. It must absorb and release heat easily and have a very low freezing point. Refrigerant must have certain qualities to work in an air conditioning system. Today most vehicles use its replacement, R134a refrigerant. Upon discovering freon emissions were contributing to the destruction of the Earth’s ozone layer, which protects its inhabitants from the sun’s most harmful UV rays, the federal government banned use of R12 refrigerant in new cars. Until 1995, this was the inert gas freon, sometimes known as R12 refrigerant. Refrigerant: The substance that flows through an air conditioning system to absorb and release heat is called refrigerant. These are the main components of a car or truck air conditioning system: Unlike other systems, its function is to remove heat and humidity from the passenger compartment and blow cooler air into it. Like most automobile systems, the air conditioning system is a complex series of motors, belts, hoses and fluid generating pressure and heat to serve its function in the automobile. It is difficult to purchase a new car or truck today without it.

Ask the drivers and passengers about the A/C and they are likely to consider it indispensable. Vehicles were not widely equipped with it until about 70 years after internal combustion vehicles were introduced. Car Air Conditioning ComponentsĪir conditioning was a later addition to cars and trucks.

The functionality of the driver and passengers, however, is dramatically enhanced by air conditioning’s cooling effect, which is why it’s important to know how to fix an A/C leak. Indeed, an A/C compressor draws power from the engine, slightly reducing the efficiency of the vehicle. The air conditioning system of a car, on the other hand, could be removed without any loss of function.
