Figure P10.24 shows the schematic diagram of a vaporcompression refrigeration system with two evaporators using Refrigerant 134 a as the working fluid. This arrangement is used to achieve refrigeration at two different temperatures with a single compressor and a single condenser. The lowtemperature evaporator operates at -18^∘ C with saturated vapor at its exit and has a refrigerating capacity of 3 tons. The higher-temperature evaporator produces saturated vapor at 3.2 bar at its exit and has a

A refrigerator uses refrigerant-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. The refrigerant enters the evaporator at 120 kPa with a quality of 34 percent and leaves the compressor at 70^∘ C. If the compressor consumes 450 W of power, determine (a) the mass flow rate of the refrigerant, ( b ) the condenser pressure, and ( c ) the COP of the refrigerator. | Numerade
