An air refrigeration system is required to produce 14.205 TR with a cooler pressure of 1,450 kPa and a refrigerator pressure of 210 kPa. Leaving air temperature are 28OC for cooler and 5OC for refrigerator. Expansion is isentropic and compression is polytropic with n = 1.34. Determine the required work and COP.

 An air refrigeration system is required to produce 14.205 TR with a cooler

pressure of 1,450 kPa and a refrigerator pressure of 210 kPa. Leaving air

temperature are 28OC for cooler and 5OC for refrigerator. Expansion is

isentropic and compression is polytropic with n = 1.34. Determine the required

work and COP.
