Compressor

In Plain English

The mechanical pump in an HVAC system that pressurizes refrigerant to keep the cooling cycle running.

Definition

The component of a refrigeration or air conditioning system that raises the pressure and temperature of low-pressure refrigerant vapor, enabling the refrigeration cycle to operate. The compressor is the heart of the refrigeration system—it consumes electrical energy and drives the flow of refrigerant through the system. Common types include scroll, screw, reciprocating, and centrifugal compressors.

Example

The 5-ton split system uses a scroll compressor in the outdoor condensing unit with an efficiency rating of 16 SEER.
