Which component operates by raising the pressure of refrigerant vapor?

The component that operates by raising the pressure of refrigerant vapor is the compressor. The primary function of the compressor in a refrigeration cycle is to take low-pressure refrigerant vapor and compress it to a higher pressure.

By increasing the pressure, the compressor raises the temperature of the refrigerant vapor as well, allowing it to efficiently release heat when it passes through the condenser. This process is crucial because it enables the refrigerant to move through the system and transition between its liquid and vapor states, facilitating heat absorption in the evaporator and subsequent heat rejection in the condenser. The compressor plays a vital role in maintaining the refrigeration cycle by ensuring that the refrigerant continuously circulates throughout the system.
