In a vapor compression refrigeration system, which component increases the refrigerant pressure?

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

Answer: (C)

In a vapor compression cycle, the pressure rise of the refrigerant is produced by the compressor. It takes low-pressure, low-temperature vapor from the evaporator and compresses it, raising both its pressure and temperature so it can move through the rest of the system. This high-pressure gas then flows to the condenser where it releases heat and becomes a high-pressure liquid, continuing the cycle. The metering device reduces pressure to the low side for evaporation, and the evaporator operates at that low pressure to absorb heat. So the component that increases refrigerant pressure is the compressor.
