Which component increases the refrigerant pressure?

Which component increases the refrigerant pressure?

• A. Compressor
• B. Condenser
• C. Metering device
• D. Evaporator

Answer: (A)

The pressure is increased by the compressor. It takes the low-pressure, low-temperature vapor returning from the evaporator and compresses it, adding energy and raising both its pressure and temperature so it can move into the condenser as a high‑pressure gas. The condenser then handles rejecting heat while the refrigerant stays at high pressure, the metering device throttles the liquid to lower pressure before it enters the evaporator, and the evaporator operates at low pressure to absorb heat. The compressor is the component that does the work to raise the refrigerant’s pressure, driving the cycle.
