Ake a look at the back of a fridge or ac unit. you will see a ‘radiator’ that is used to remove heat from the r134a fluid that circulates within the refrigeration system. using this heat exchanger, the refrigerant-134a at 1 mpa and 90oc is to be cooled to 1 mpa and 30oc by air. the air enters at 100 kpa and 27oc with a volume flow rate of 600 m3/min and leaves at 95 kpa and 60oc. determine the mass flow rate of the refrigerant.[20]
