What is the role of the compressor in a refrigeration system?

The compressor plays a crucial role in a refrigeration system by circulating the refrigerant while simultaneously increasing its pressure. This process is essential for the refrigeration cycle to function effectively.

When the refrigerant enters the compressor, it is in a low-pressure gaseous state. The compressor compresses this gas, resulting in an increase in both pressure and temperature. This high-pressure gas is then sent to the condenser, where it can release heat and transition into a liquid state. The ability of the compressor to maintain the flow of refrigerant and elevate its pressure is vital for the continuous operation of the refrigeration cycle, allowing heat to be absorbed from one area and expelled in another.

In contrast, condensing the refrigerant, absorbing heat, and maintaining system temperature are functions associated with other components in a refrigeration system, such as the condenser, evaporator, and thermal control systems. These aspects are equally important but serve different purposes in the overall operation.
