What is a primary function of an HVAC system's compressor?

The primary function of an HVAC system's compressor is to pump refrigerant through the system. The compressor plays a vital role in the refrigeration cycle by circulating the refrigerant, which absorbs heat from the indoor air and transfers it outside. During this process, the compressor compresses the refrigerant gas, increasing its pressure and temperature before sending it to the condenser. This action not only facilitates the removal of heat from indoors but also enables the entire system to cool the air effectively.

In contrast, while filtering impurities from the air, maintaining indoor humidity levels, and providing fresh air intake are important aspects of ventilation and air quality, these functions are performed by other components of the HVAC system, such as air filters, humidistats, and ventilators, respectively. The compressor specifically focuses on the movement of refrigerant, which is essential for heat exchange and temperature control in the HVAC system.
