Condensers are essentially heat exchangers that look like radiators, but they are smaller and thinner. They are generally made of aluminium and are mounted at the back of the radiator using specific mounts so that they get a constant airflow when the AC is working.
The compressor is actually a large electric pump that pressurises the refrigerant gas as part of the process of turning it back into a liquid. It is generally connected to the engine via a belt drive which is connected to the crankshaft pulley.
The expansion valve is located near the evaporator inlet. It monitors the pressure and temperature in order to ensure that the exact amount of refrigerant safely enters the evaporator.
It looks like a metal can with an inlet and outlet. The liquid refrigerant moves to the receiverdryer and inside there is a small reservoir vessel for the liquid refrigerant. In this compartment any moisture that may have leaked into the refrigerant is removed.
They too look like radiators, but are little thicker and smaller than the condenser. Generally it is located deep under the instrument panel. This is the last stop for the liquid refrigerant where it again turns into gas. A fan then blows the cool air inside cabin from the evaporator.
The AC system employs a host of hoses and pipes that are clamped by jubilee clips. They can be both metal and rubber and one must take care of these components and replace them incase they become hard.
