The _______ converts refrigerant into high-temp, high pressure gas and sends it to the A/C Condenser.

• A. Condenser
• B. A/C Compressor
• C. Expansion Valve
• D. Receiver Dryer

Answer: (B)

In a vehicle air conditioning system, the compressor is the component that takes in low-pressure refrigerant vapor from the evaporator and compresses it into high-pressure, high-temperature gas, which is then pushed to the condenser to release heat. This compression is essential because it raises the refrigerant’s pressure and temperature so the condenser can effectively reject heat and turn the gas into a liquid. The other parts do different jobs: the condenser removes heat from the high-pressure gas and condenses it into a liquid; the expansion valve lowers the pressure to allow the liquid to warm up and vaporize in the evaporator, providing cooling; and the receiver/drier stores liquid refrigerant and filters out moisture.
