Co Hew De Layer et Q10) 8 grades In the refrigeration system shown, a heat exchanger is used to superhent the vapor entering the compressor while subcooling the liquid exiting from the condenser. Consider a system of this type that uses refrigerant-134a as its refrigerant and operates the evaporator at -10.09 C, and the condenser at 900 kPa. The maximum temperature in cycle is 80 C. The heat exchanger provides 9.51 Cof subcooling at the throttle valve entrance. Assume the refrigerant leaves the evaporator as a saturated vapor and the compressor is isentropic Q10-1) Complete the following table State (1) (2) (3) (4) h (kJ/kg) 0.50 grade cell TC 0.50 grade/cell (5) (6) Show how hi, was calculated: (1.0 grades) Expression 0.5 grade COPR Q10-ii) What is the COP for this system when it runs as a refrigerator Value 0.5 grade COPR
