An air refrigerator working on the principle of the Bell - Coleman cycle. The air into the compressor is at 1 atm at -10\deg C. It is compressed to 10 atm and cooled to 40\deg C at the same pressure. It is then expanded to 1 atm and discharged to take a cooling load. The air circulation is 1 kg/s. The isentropic efficiency of the compressor = 80% The isentropic efficiency of the expander = 90% Find the following: i) Refrigeration capacity of the system ii) C.O.P of the system Take \gamma = 1.4, Cp = 1.00 kJ/kg \deg C.
