What is the function of the compressor in a vapor-cycle cooling system?

The function of the compressor in a vapor-cycle cooling system is to circulate refrigerant through the system. The compressor plays a crucial role by taking in low-pressure gas refrigerant and compressing it into a high-pressure gas. This process not only increases the temperature and pressure of the refrigerant but also sets the stage for its flow through various components of the system, including the condenser, expansion valve, and evaporator.

By circulating the refrigerant, the compressor enables the entire cooling cycle to function effectively, allowing for heat absorption in the evaporator and subsequent heat rejection in the condenser. This continuous movement is essential for maintaining the desired temperature and comfort level in the cabin environment. Other components of the system, such as the condenser and evaporator, rely on the compressor to facilitate the transfer of heat, making it a vital part of the overall cabin atmosphere control system.
