2. A Refrigerant-22 system is arranged as shown in the figure below. Assume isentropic compression and frictionless flow. The following data are given: condensing temperature = 90°F; evaporator A has a capacity of 5 tons and an evaporating temperature of -20°F; evaporator V has a capacity of 10 tons and an evaporating temperature of -70°F; vapor leaves each evaporator in dry and saturated condition; = 84°F, , 20°F, -5°F and -55°F. Draw schematic P-h and T-s diagrams for the cycle and determine (a) The C.O.P for the system, (b) The compressor displacement, for each compressor, and (c) The theoretical horsepower input for each compressor. (16) Liquid cooler (15) (1) (2) (10) (11) Cond. (14) Superheater A Evap. A (12) M (9) Evap. B (20) Comp. A (7) (19) (18) Comp. B (13) (17) Superheater B 2.
