.) An actual 35 TR refrigerating system operates using R22 refrigerant. Refrigerant enters the evaporator at 264.29 kPa and leaves saturated vapour at 244.83 kPa. Refrigerant enters the compressor at – 10°C. Refrigerant leaves the compressor at condensing pressure of 1400 kPa and 70°C and leaves the condenser at 30°C. Compression process is polytropic with n= 1.23. Draw the p-h diagram of the cycle (labeling the pressures and temperatures in each condition). (b) Define and determine the necessary enthalpies and determine the following: (c) IHP and (d) heat rejected during compression, kW

Transcribed Image Text:1.) An actual 35 TR refrigerating system operates using R22 refrigerant. Refrigerant enters the
evaporator at 264.29 kPa and leaves saturated vapour at 244.83 kPa. Refrigerant enters the
compressor at – 10°C. Refrigerant leaves the compressor at condensing pressure of 1400 kPa
and 70°C and leaves the condenser at 30°C. Compression process is polytropic with n = 1.23.
Draw the p-h diagram of the cycle (labeling the pressures and temperatures in each
condition). (b) Define and determine the necessary enthalpies and determine the following:
(c) IHP and (d) heat rejected during compression, kW
