An air refrigeration system operating on a closed cycle is required to produce

of refrigeration with a cooler pressure of

and a refrigerator pressure of

. Leaving-air temperatures are

for the cooler and

for the refrigerator. Assuming a theoretical cycle with isentropic compression and expansion, no clearance and no losses, determine (a) the mass flow rate, (b) the compressor displacement, (c) the expander displacement, (d) the heat rejected in the air cooler and (e) the COP.
