2) An aircraft refrigeration plant has to handle a cabin load of 30 TR. The atmospheric
temperature is 17°C. The atmospheric air is compressed to a pressure of 95 kPa and a
temperature of 30°C due to ram action. The air is then further compressed in the compressor to
475 kPa, cooled in a heat exchanger to 67°C, expanded in a turbine to 100 kPa and supplied to
the cabin. The air leaves the cabin at a temperature of 27°C. Calculate the mass of air circulated
per minute and the COP. For air, take cp = 1.004 kJ/kg.K and k = 1.4.

Expert Solution

Step 1: Write the given data with suitable variables-

$R E equals 30 space TR straight T subscript 1 equals 17 degree straight C straight P subscript 2 equals 95 space kPa straight T subscript 2 equals 30 degree straight C straight P subscript 3 equals 475 space kPa straight T subscript 4 equals 67 degree straight C straight T subscript 6 equals 27 degree straight C$
