An R-134a vapor compression cycle, has a refrigeration load of 3 tones. The evaporator and condenser temperatures are -20°C and 40°C respectively. Determine (a) heat rejected in the condenser in kW (b) the isotropic discharge temperature. If there is a 5°C of superheating of vapor before it enters the compressor, and 5°C sub cooling of liquid before it flows through the expansion valve, determine the above quantities. (Cp liquid and Cp vapor values are 0.963 and 0.6165 kJ/kg K respectively).

Question 2 of 4 - / 25 An office building requires a heat transfer rate of 30 kW to maintain theinsidetemperature at 21°Cwhen theoutsidetemperature is O°C. Avapor-compression heat pump with Refrigerant 134a astheworkingfluid isto beused to provide the necessary heating. The compressoroperates adiabatically with an isentropic efficiency of 82%. Determine appropriate evaporator and condenser pressures of a cyclefor this purpose assuming ATcond = ATevap = 10°C, as shown in the T-sdiagram.
