A 1-ton (200 Btu/min) vapor-compression refrigerator uses R-134a as the refrigerant. Evaporation occurs at 10 F and condensation occurs at 100 F. The compressor is reversible and adiabatic. The refrigerant leaves the evaporator at 20 F and leaves the condenser at 95 F. The heating and cooling processes are both at constant pressure. Determine the steady-state power (hp) into the compressor.
