The cooling coil of an air - conditioning system is a heat exchanger in which air passes over tubes through which refrigerant 22 flows. air enters with a volumetric flow rate of 40 m3/min at 27degreec, 1.1 bar. and exits at 15degreec. 1 bar. refrigerant enters the tubes at 7 bar with a quality of 16% and exits at 7 bar, 15degreec. ignoring heat transfer from the outside of the heat exchanger and neglecting kinetic and potential energy effects, determine at steady state the mass flow rate of refrigerant, in kg/min. the rate of energy transfer, in kj/min. from the air to the refrigerant.
