A vapor-compression refrigeration cycle with Refrigerant 134a as the working fluid operates with an evaporator temperature of 508F and a condenser pressure of 180 lbf/in.2 Saturated vapor enters the compressor. Refrigerant enters the condenser at 1408F and exits as saturated liquid. The cycle has a refrigeration capacity of 5 tons. Determine
(a) the refrigerant mass flow rate, in lb/min.
(b) the compressor isentropic efficiency.
(c) the compressor power, in horsepower.
(d) the coefficient of performance.
Plot each of the quantities calculated in parts (b) through (d) for compressor exit temperatures varying from 1308F to 1408F.
