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 5Â°C and condensing temperature of 50Â°C. The performance data are based on 3Â°C liquid sub-cooling and 8Â°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.
