What is the role of a compressor in an HVAC system?

The primary role of a compressor in an HVAC system is to pump refrigerant throughout the system. This process is crucial for the refrigeration cycle, which is fundamental to heating and cooling processes. The compressor takes in refrigerant that is low in pressure and low in temperature, compressing it to a higher pressure and temperature. This action not only moves the refrigerant through the system but also prepares it to release heat when it reaches the condenser.

Pumping the refrigerant facilitates its circulation between various system components, such as the evaporator and the condenser, allowing for effective absorption and rejection of heat, which ultimately results in maintaining the desired indoor temperature. This function is essential for the HVAC system’s efficiency and performance.
