Problem 3 A vapor compression heat pump cycle requires that the evaporator and condenser operate within 10°C of their respective heat reservoirs. The cycle employs R134a as the working fluid, which exits the evaporator as a saturated vapor and exits the condenser as a saturated liquid. The compressor operates with an isentropic efficiency of 82%. If the desired inside temperature is 21 °C and the outside temperature is 0 °C, determine: The appropriate cycle pressures, The compressor power in kW, Compare the actual coefficient of performance to the coefficient of performance for a Carnot heat pump cycle operating between the inside and outside temperatures given above.
