The HVAC compressor is a crucial component responsible for compressing the refrigerant, playing a pivotal role in the heating and cooling processes of an HVAC system. Let’s delve into its function and the types of compressors available:

What Does an HVAC Compressor Do?

To comprehend the workings of a compressor, understanding refrigeration is essential. Refrigeration is the process by which air conditioners extract heat from a space and transfer it outside, thereby cooling the indoor temperature.

Evaporator Coil: The refrigerant absorbs heat, changing from a liquid to a low-pressure gas.

Compressor: The compressor compresses the refrigerant, transforming it into a high-pressure, high-temperature gas.

Condenser: The hot gas passes through the condenser, where outside air dissipates heat, turning the gas into a high-pressure liquid.

Expansion Valve: The pressure and temperature of the liquid refrigerant drop, converting it back into a low-pressure gas and restarting the cycle.
