What role does the compressor play in a refrigeration system?

In a refrigeration system, the compressor is pivotal in the refrigeration cycle, primarily responsible for circulating and compressing refrigerant gas. When the refrigerant gas enters the compressor, it is at a low pressure and temperature. The compressor increases the pressure of this gas, which also raises its temperature due to the principles of thermodynamics.

This high-pressure, high-temperature gas then flows to the condenser, where it releases heat to the environment and transforms into a liquid. By increasing the pressure of the refrigerant, the compressor enables the refrigerant to flow through the system, allowing heat absorption in the evaporator and effectively cooling the desired area. This function of circulating and compressing is essential for maintaining the cycle that allows refrigeration systems to operate efficiently and effectively.
