An ideal vapor-compression refrigeration cycle that uses refrigerant-134a as its working fluid maintains a condenser at 800 kPa and the evaporator at -12^∘ C. Determine this system's COP and the amount of power required to service a 150 kW cooling load. | Numerade

A refrigerator operates on the ideal vapor-compression refrigeration cycle with refrigerant-134a as the working fluid. The refrigerant evaporates at -10^∘ C and condenses at 57.9^∘ C The refrigerant absorbs heat from a space at 5^∘ C and rejects heat to ambient air at 25^∘ C. Determine (a) the cooling load, in kJ / kg and the COP, ( b ) the exergy destruction in each component of the cycle and the total exergy destruction in the cycle, and ( c ) the second-law efficiency of the compressor, evapo

SOLVED:An actual refrigerator operates on the vaporcompression refrigeration cycle with refrigerant-22 as the working fluid. The refrigerant evaporates at -15^∘ C and condenses at 40^∘ C. The isentropic efficiency of the compressor is 83 percent. The refrigerant is superheated by 5^∘ C at the compressor inlet and subcooled by 5^∘ C at the exit of the condenser. Determine (a) the heat removed from the cooled space and the work input, in kJ / kg and the COP of the cycle. Determine ( b ) the same p
