Heating, Ventilation, and Air Conditioning (HVAC ) Electrical Practice Test

The purpose of a compressor in an HVAC system is to pump refrigerant through the system, which is crucial for the refrigeration cycle. The compressor takes low-pressure refrigerant gas from the evaporator, compresses it, and then releases it as high-pressure gas into the condenser. This process not only enables the movement of refrigerant but also transforms the refrigerant into a state that allows it to release heat when it reaches the condenser. By circulating the refrigerant, the compressor helps to maintain the necessary pressure and flow within the system, facilitating effective heat exchange and ultimately cooling the indoor environment.

In summary, the compressor is essential for the operation of the HVAC system, ensuring the refrigerant moves through the system efficiently and effectively removes heat from the indoor air to provide cooling.
