Round your final answers to three decimal places. The liquid leaving the condenser of a 115,000-Btu/h heat pump using refrigerant-134a as the working fluid is subcooled by 9.5 degree F. The condenser operates at 160 psia and the evaporator at 50 psia. How does this subcooling change the power required to drive the compressor as compared to an ideal vapor-compression refrigeration cycle?
