The refrigerator-freezer unit, shown in the schematic below, uses R-134a as the working fluid and operates on an ideal vapor-compression cycle. The temperatures in the condenser, refrigerator, and freezer are 25oC, 2oC, and -20oC, respectively. The mass flow rate of the refrigerant is 0.1 kg/s. If the refrigerant quality at the refrigerator exit is 0.4, determine the rate of heat removal from
The refrigerator and
Freezer. Also, determine
The compressor power input and
The COP of the unit.
