Car Air Conditioning - Car Air Con Information For All Vehicle Air Conditioning…

Looking For Car Air Conditioning Parts?

Car air conditioning parts can be broken down into 5 distinct components, and these are as follows:

Car air conditioning compressor:

Car Air Conditioning CompressorThe compressor is the main engine of the air conditioning system. It is powered by a drive belt connected to the crankshaft of the engine. When the car air con is activated it is the job of the compressor to pump refrigerant vapour, under high pressure, to the condenser.

Car air conditioning condenser:

Once the refrigerant vapour is passed to the condenser it is its job to convert this to a liquid. The condenser is mounted in front of the engine’s radiator, and it looks not dissimilar to a radiator itself. Because of the high pressure that is driving it in the vapour is condensed to a liquid, and this generates a large amount of heat. Air flowing around the outside of the condenser then removes this.

Car air conditioning receiver:

Now it is a liquid the refrigerant is passed to the receiver. This is a small reservoir for this liquid, and it removes any moisture that could have leaked into the refrigerant. This is important as any moisture in the system could cause problems; potentially ice crystals could cause blockages and damage to the system.

Car air conditioning expansion valve:

From the receiver the refrigerant passes to the expansion valve. Pressure is removed here from the liquid refrigerant; then it can expand and change to refrigerant vapour in the evaporator.

Car air conditioning evaporator:

The evaporator is also not dissimilar in appearance to a car radiator itself. It is normally mounted inside the passenger compartment. As the refrigerant is passed into the evaporator, it vaporises and absorbs heat from the air inside the car. The blower fan inside expels air over the outside of the evaporator, and thus cold air is circulated inside the vehicle. On the external side of the evaporator, the moisture in the air is reduced, and the condensate is collected and drains away.
