What is the primary function of the compressor in an A/C system?

The primary function of the compressor in an A/C system is to pump refrigerant through the system. The compressor serves as the critical component that circulates refrigerant, enabling it to absorb heat from the indoor air and release it outside. It compresses the refrigerant gas, raising its pressure and temperature, which facilitates the movement of refrigerant through the evaporator and condenser coils. This compression is essential in ensuring that the system can effectively transfer heat, maintaining the desired temperature in the conditioned space.

By achieving the necessary pressure differentials, the compressor allows the refrigerant to flow through the various components of the A/C system, thereby enabling the cooling process to take place. As the refrigerant travels from the evaporator to the condenser, it undergoes phase changes that are critical to the overall operation of the air conditioning system.
