An ideal vapor-compression refrigeration system operates at steady state with Refrigerant 134a as the working fluid. Superheated vapor enters the compressor at 30 lbf/in2, 20F, and saturated liquid leaves the condenser at 140 lbf/in2. The refrigeration capacity is 5 tons.
Determine:
-the compressor power in hp
-the rate of heat transfer from the working fluid passing through the condenser, in Btu/min
-the coefficient of performance
