Which component of the refrigeration cycle typically operates at a higher pressure?

In a refrigeration cycle, the compressor is the component that typically operates at a higher pressure. The primary function of the compressor is to increase the pressure of the refrigerant vapor coming from the evaporator. By compressing the refrigerant, it elevates its pressure and temperature, enabling it to move to the condenser where heat is released.

The process begins when the refrigerant absorbs heat in the evaporator, turning into vapor. This vapor is then drawn into the compressor, where it is compressed and thus increases its pressure. The high-pressure vapor then moves to the condenser, where it releases heat and condenses back into liquid form. This sequence is crucial for the refrigeration cycle to function effectively.

Other components operate at lower pressures. For instance, the evaporator operates at low pressure as it absorbs heat from the environment, while the expansion valve lowers the pressure of the refrigerant further before it enters the evaporator. The condenser, while it deals with high pressure, is downstream from the compressor and does not reach the same pressure levels as the compressor itself. Thus, it is clear why the compressor is recognized for functioning at a higher pressure within the refrigeration system.
