- noun a refrigerant in vapour form is pressurized in the compressor, air-cooled in the condenser and becomes a liquid which passes through the receiver-drier into the expansion valve where it expands into low-pressure liquid. It then flows through the evaporator where it expands again and starts to boil, absorbing heat from the core and cooling the air going into the passenger compartment. The compressor draws off the low-pressure vaporized refrigerant and recycles it.
- A thermodynamic process whereby a refrigerant accepts and rejects heat in a repetitive sequence.
