A refrigerator operates on the ideal vapor-compression refrigeration cycle with refrigerant-134a as the working fluid. The refrigerant evaporates at - 10oC and condenses at 57.9oC. The refrigerant absorbs heat from a space at 5oC and rejects heat to ambient air at 25oC. 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.
(c) The second- law efficiency of the compressor, evaporator, and the cycle.
