1.A vapor-compression refrigeration system, using R-134a, is being used to keep a food storage room under desired cold temperature. At steady state conditions, the evaporator temperature is 0°C, and the condenser temperature is 48°C. The cooling load on the refrigeration system is 8 tons of refrigeration. Calculate the refrigerant flow rate, the compressor power if the compressor efficiency is 78%, and C.O.P.
