Q4) A refrigeration system using refrigerant 22 is to have a refrigerating capacity of 80 kW. The cycle is a standard vapor-compression cycle in which the evaporating temperature is -8°C and the condensing temperature 42°C. (a) Determine the volume flow of refrigerant measured in cubic meters per second at the inlet to the compressor. (b) Calculate the power required by the compressor. (Ans. (a) 0.0325 mis and (b) 19.442 kW).
