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 is 42 C. (a) Determine the volume flow of refrigerant measured in cubic meter per second at the inlet to the compressor. Calculate the power required by the compressor. At the entrance to the evaporator what is the fraction of vapor in the mixture expressed both on a mass basis and a volume basis? (b) (c)
