Freezing cycle and refrigerant Chapter 6. Freezing cycle and refrigerant 6-1. Freezing cycle (Freezing principle/Refrigerant gas circulation diagram) 6-1-1. Freezing principle Freezing is an operation of maintaining a lower temperature (generally 0°C) than the natural temperature (usually ambient temperature surrounding us). This requires an insulated space, refrigerant (R134a) to absorb the heat and the circulation circuit (compressor, condenser, evaporator etc.) to operate the phase change of the refrigerant. 6-1-2.

Freezing is an operation of maintaining a lower temperature (generally 0°C) than the natural temperature (usually ambient
temperature surrounding us). This requires an insulated space, refrigerant (R134a) to absorb the heat and the circulation
circuit (compressor, condenser, evaporator etc.) to operate the phase change of the refrigerant.
