Question

14-88 Atmospheric air at 1 atm, 32°C, and 95 percent rela- tive humidity is cooled to 24°C and 60 percent relative humid- ity. 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 4°C and its condenser at a saturation temperature of 39.4°C. The con- denser rejects its heat to the atmospheric air. Calculate the exergy destruction, in kJ, in the total system per 1000 m3 of dry air processed. 2 Expansion Condenser Compressor valve 4 Evaporator 24°CI 32°C -95% atm Condensate FIGURE P14-88

please write neat and include your approach to the problem along with any assumptions youre operating under
