How Does an Air-Conditioning Compressor Work on a Pontiac?

A Pontiac car.

The compressor inside any Pontiac vehicle is integral to the vehicle's air-conditioning system. Despite being an auto air-conditioning system, the entire unit operates the same way as any standard air conditioner found inside a home or building.

Function

The air-conditioning compressor inside a Pontiac is used to drive refrigerant fluid through the rest of the conditioning unit.

Fluid

The compressor spins in much the same way a fan does. This spinning is used to move the refrigerant through the air-conditioning unit, cooling the inside of your car.

Compression

When refrigerant is inside the tight compartments of the compressor, it naturally begins to heat up. This causes it to flow from the compressor to the condenser coil.

Evaporator Coil

The fluid then flows into the evaporator coil of the Pontiac's air conditioning unit. At this point it cools down.

Evaporator

The refrigerant then flows from the evaporator coil to the evaporator unit. Tiny fans then blow the cold air out of the air-conditioner and into the inside of the Pontiac car, cooling it down.
