Atmospheric air at 1 atm, 32oC, and 95 percent relative humidity is cooled to 24oC and 60 percent relative humidity. A simple ideal vapor-compression refrigeration system using refrigerant-134a as the working fluid is used to provide the cooling required. It operates its evaporator at 4oC and its condenser at a saturation temperature of 39.4oC. The condenser rejects its heat to the atmospheric air. Calculate the exergy destruction, in kJ, in the total system per 1000 m3 of dry air processed.
