Air Conditioning 101 by Classic Auto Air
Here are the basics in Air Conditioning
The air conditioning system in your car is comprised of a compressor, condenser, expansion valve, receiver/drier, and evaporator. Refrigerant (also known as Freon) is compressed in the compressor. In the condenser, gas is cooled to a liquid state and travels to the expansion valve. As the liquid refrigerant goes through the expansion valve it rapidly cools in the evaporator. A fan blows over the evaporator and cools the air that blows out your vents.
5 Easy Areas
1. Evaporator with Blower Fan: In order to remove the heat from the air in the vehicle, the A/C evaporator allows the refrigerant to absorb the heat from the air passing over it. The blower fan moves cool air out into the car interior.
2. Compressor: The compressor pumps and circulates the refrigerant through the system.
3. Condenser: The condenser is a heat exchanger mounted at the front of the vehicle. Heat drawn out of the interior of the car is expelled here.
4. Receiver/Drier: The drier not only dries refrigerant, it also filters the refrigerant and stores it under certain operating conditions.
5. High-Pressure Switch: A pressure switch is used to shut down the system if high or low pressure is detected, basically it acts as a safety switch.
