The evaporator looks like the condenser’s cousin, with coils of its own, ...

How does a car A/C compressor work?

The compressor then pumps the refrigerant gas through hoses and into the condenser. Condenser: The car A/C condenser receives refrigerant gas under high pressure from the compressor and exposes it to significantly lower outside temperatures , much the same way a radiator exposes engine coolant to atmospheric temperature.

Why is refrigerant not a solid?

What is the only mechanical component in an air conditioning system?

Compre ssor: The compressor is the only mechanical component in the air conditioning system. The compressor is powered by the mechanical motion of the crankshaft to put refrigerant under immense pressure, raising its temperature in the process. The compressor then pumps the refrigerant gas through hoses and into the condenser.
