A standard vapor compression system produces 20 tons of refrigeration using R-12 as a refrigerant while operating between a condenser temperature of 41.6 oC and an evaporator temperature of –25 oC. Determine (a) the refrigerating effect in kJ/kg, (b) the circulating rate in kg/s, (c) the power supplied, (d) the COP, (e) the heat rejected in kW, and (f) the volume flow rate in L/s.
