1. Compresses the refrigerant: The compressor draws in low-pressure, low-temperature refrigerant gas from the evaporator.
2. Increases pressure and temperature: The compressor compresses the refrigerant gas, significantly increasing its pressure and temperature.
3. Pushes refrigerant to the condenser: The compressed refrigerant is then pushed through the condenser coils, where it releases heat to the outside air.
4. Changes refrigerant state: As the refrigerant cools in the condenser, it transitions from a hot gas to a liquid under high pressure.
5. Prepares for the cycle to repeat: The liquid refrigerant then flows back to the evaporator, ready to absorb heat from the truck's cabin and begin the cycle again.
In essence, the compressor is responsible for:
* Moving the refrigerant through the system.
* Increasing the refrigerant's pressure and temperature.
* Facilitating the transfer of heat from the cabin to the outside air.
Without a functioning compressor, the AC system wouldn't be able to cool the truck's cabin effectively.
