2. An air refrigerator working on the principle of Bell-Coleman cycle. The air into the compressor is at 1 atm at -10°C. It is compressed to 10 atm and cooled to 40°C at the same pressure. It is then expanded to I atm and discharged to take 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) ii) Refrigeration capacity of the system C.O.P of the system
