Example 2: Refrigerant R-134a enter the compressor of a has a refrigerantor a superheared vapor at 0.14MPa and -10°C at arate of 0.05kg/sec and leave at 0.8Mp and 50°C. The refrigerant cooled in the condenser to 26°C and 0.72Mpa is throttled to 0.15MPa.Disregradingany heat transfere and pressure drop in the connecting line between the components. Determine: a) The rate of heat removed from the refrigerated space b) The power input to the compressor. c) Isentropic eff of the compressor d) COP of the refrigerantor.
