A refrigeration compressor of 50 m bore and 40 mm stroke operates at a speed of 1460 rmp between condensing and evaporating pressure limits of 1.219 MPa and 0.151 MPA. The clearance ratio is 1.18, specific volume of refrigerant at suction is 0.11 k3/kg and the enthalpy change of refrigerant in the evaporator is 93.7 kJ/ kg. Calculated the refrigeration load the compressor can serve.
