Evaluate the performance of an ideal, single-stage, vapor compression refrigeration cycle using refrigerant R-134a and operating with an evaporating temperature of 20F and a condensing temperature of 100F. Assume 1 ton of refrigeration occurring in the evaporator. a. Draw the cycle on an R-134a P-h diagram. Label point 1 as exit of evaporator, point 2 as exit of compressor, point 3 as exit of condenser, and point 4 as exit of expansion valve. b. C. d. In a table, clearly provide the temperature (F), pressure (psia), specific enthalpy (BTU/lb) and phase at each of the four points. Determine the mass flow (lb/hr) of refrigerant. Determine the heat of compression (compressor work) (BTU/hr). e. Determine the heat rejection in the condenser (BTU/hr). f. Determine the COP. g. Determine the refrigerating efficiency.
