What is the primary function of a compressor in a refrigeration system?

The primary function of a compressor in a refrigeration system is to circulate refrigerant throughout the system. The compressor plays a critical role in the refrigeration cycle by taking in low-pressure refrigerant gas from the evaporator and compressing it into high-pressure gas, which subsequently moves to the condenser. This process not only aids in the circulation of the refrigerant but also increases its pressure and temperature, enabling it to release heat in the condenser.

In the context of the refrigeration cycle, the compressor is essential for maintaining the flow of refrigerant, thus facilitating the heat absorption in the evaporator and the heat expulsion in the condenser. It ensures that the entire system operates efficiently by continuously moving the refrigerant, which is necessary for heat exchange to occur effectively.
