Condenser Compressor An ideal vapor-compression refrigeration cycle is modified to include a counter-flow heat exchanger as shown. Refrigerant 134a leaves the evaporator as saturated vapor at 0.10 MPa and is heated at constant pressure to 20°C before entering the compressor. Following isentropic compression to 1.4 MPa, the refrigerant passes through the condenser and exits at 45°C and 1.4 MPa. The liquid then passes through the heat exchanger and enters the expansion valve at 1.4 MPa. The mass flow rate of...

Refrigerant 134a flows through an ideal vapor compression heat pump system with a heating capacity of 60,000 Btu/hr. The condenser operates at 200 psi, and the evaporator temperature is 0°F. The refrigerant is a saturated vapor at the evaporator exit and a saturated liquid at the condenser exit. The temperature at the compressor exit is 180°F. Assuming the compressor is not 100% isentropic, determine: a) Mass flow rate (lbm/min) b) Compressor power (hp) c) Isentropic compressor efficiency d) Coefficient of...

11-11 A refrigerator operates on the ideal vapor-compression refrigeration cycle and uses refrigerant-134a as the working fluid. The condenser operates at 1.6 MPa and the evaporator at -6oC. If an adiabatic, reversible expansion device were available and used to expand the liquid leaving the condenser, how much would the COP improve by using this device instead of the throttle device?
