A commercial refrigerator using R-134a as a refrigerant is used to keep the cooled environment at -35 C. The refrigerator releases the waste heat to the cooling water that enters the condenser at 18 C at 0.25 kg / s and leaves the condenser at 26 C. The refrigerant enters the condenser at a pressure of 1.2 MPa and a temperature of 50 ° C, and leaves the condenser at the same pressure, supercooled at 5 ° C.
