Components of an Auto AC Unit


The car stays cool by using the serpentine belt to compress and circulate the refrigerant in its gaseous form.


To refrigerate something, you should first compress the refrigerant from its gaseous state. Then, transfer the compressed refrigerant to a condenser where it will turn into a liquid (much like a radiator). This process removes heat from the high-pressure refrigerant, which lowers the temperature.


To safeguard the air conditioning system against water or debris, it is crucial to filter the liquid refrigerant while under high pressure.

Thermal Expansion Valve OR Orifice Tube

Car air conditioners decrease the refrigerant pressure using either thermal expansion valves or orifice tubes. This process turns the refrigerant into gas and helps control its flow.


The evaporator, which cools the air, is located at the back of the dashboard. It works by expanding liquid refrigerant, just like a radiator, and uses fins, pipes, and a fan to circulate the cooled air into the passenger compartment.
