A refrigeration circuit as found in heat pumps, air conditioning systems and refrigeration systems is made up of four elements: a compressor, a condenser, a pressure regulator and an evaporator. In this circuit, the role of the refrigeration compressor is to compress the refrigerant gas, thus providing it with the mechanical energy required to create cold.
There are three main types of technology used for refrigeration compressors:
- Piston refrigerator compressors
- Screw refrigeration compressors
- Scroll refrigeration compressors (spiral compressors)
As well as three types of systems:
