Example Air conditioning unit uses Freon R-22 for conditioned office at 25 C. The evaporating temperature is 17 C and the condensing temperature is 47 C. The compressor is reciprocating and-single acting with number of cylinders of 4, volumetric efficiency of 0.9, number of revolution is 900 rpm cylinder dimensions of L/D is 1.25. If the compressor power is 3 kW and mechanical efficiency of 0.9, estimate the followings: the refrigerant mass flow rate in kg/min, refrigeration capacity in TR, cylinder dimensions, condenser heat load, coefficient of performance and relative efficiency. and
