3) A refrigeration plant operates on the vapor-compression cycle and uses refrigerant-134a as the working fluid. The plant has a refrigeration capacity of 190kW. Refrigerant-134a leaves the condenser as a saturated liquid with a pressure of 900kPa, and it leaves the evaporator as a saturated vapor with a pressure of 140kPa. The compressor has an isentropic efficiency of 90% and there is no pressure loss in the piping of the system. Determine a) the mass flow rate of the refrigerant b) the power input to the compressor in kW c) the exergy destruction rates of the compressor and expansion valve in kW if the dead state temperature is 15°C.

Question
Transcribed Image Text:3) A refrigeration plant operates on the vapor-compression cycle and uses refrigerant-134a as
the working fluid. The plant has a refrigeration capacity of 190kW. Refrigerant-134a leaves
the condenser as a saturated liquid with a pressure of 900kPa, and it leaves the evaporator as
a saturated vapor with a pressure of 140kPa. The compressor has an isentropic efficiency of
90% and there is no pressure loss in the piping of the system. Determine
a) the mass flow rate of the refrigerant
b) the power input to the compressor in kW
c) the exergy destruction rates of the compressor and expansion valve in kW if the dead state
temperature is 15°C.
