Question 3 [15 marks] Catalogue data of 4.8 % clearance R134a compressor with piston displacement of 2 m³/min shows the capacity to be 12.7 TR, when the suction conditions are 20 °C and 5.7160 bar and condensing temperature is 40 °C. The refrigerant leaves the condenser as saturated liquid. At these compressor conditions, calculate: a) The mass flow rate of refrigerant at compressor inlet b) The actual volumetric efficiency c) The clearance volumetric efficiency d) The clearance volume, in m³/min 2 [9 marks] [3 marks] [3 marks] [2 mark]
