Catalogue data for R-32 compressor with a displacement of 80 L/s show the capacity to be 8 tons when the suction conditions are 0.2 MPa and -20°C and condensing temperature is 50°C. The refrigerant leaves the condenser as saturated liquid. Calculate the actual volumetric efficiency and the brake work of the compressor if the compressor efficiency is 65%. By using the R-32 chart provided.
