Catalogue data for a six-cylinder refrigerant 22 compressor operating at 29 r/s (revolution per second) indicates a refrigerating capacity of 96.4 kw and a power requirement of 28.9 kw at an evaporating temperature of 5°c and condensing temperature of 50°c. the performance data are based on 3°c liquid sub-cooling and 8°c super-heating of suction gas entering the compressor. the cylinder bore (diameter) is 67mm and piston stoke is 57mm. compute: (a) the clearance volumetric efficiency if the clearance volume is 4.8% (b) the actual volumetric efficiency (c) compression efficiency 1.
