What is the primary role of a compressor in a refrigeration cycle?

The primary role of a compressor in a refrigeration cycle is to compress refrigerant vapor and circulate it through the system. This function is vital for the overall process, as the compressor increases the pressure and temperature of the refrigerant vapor, making it capable of releasing heat when it enters the condenser. By compressing the refrigerant, the compressor transforms it from a low-pressure gas into a high-pressure gas, which is essential for enabling the refrigeration cycle to continue.

In addition to compression, the compressor ensures the continuous movement of refrigerant throughout the system, creating the necessary flow that allows for heat exchange to occur in both the evaporator and condenser. This circulation is crucial for the absorption and rejection of heat in the refrigeration cycle, thus maintaining the desired temperature in the conditioned space.

Understanding the compressor's function helps clarify its importance in the system and highlights its role in facilitating the heating and cooling processes that define modern air conditioning and refrigeration systems.
