There is a vapor compression type refrigeration cycle using the
refrigerant HFC 134 a. In the condenser, it is isostatically
cooled, the condensation temperature is 50 ° C., and the condenser
outlet is the compressed liquid at 45 ° C. In the evaporator, it is
isothermally heated, the evaporation temperature is 10 ° C. and the
outlet of the evaporator is heated steam at 15 ° C. When the
expansion valve performs isenthalpic expansion, and the adiabatic
efficiency of the...
