Task 5 Two evaporator compression refrigeration system as shown in the figure 1 below uses refrigerant- 134a as a working fluid. Evaporator 1 operates at 0 °C, evaporator 2 operates at -26.4°C, and the condenser operates at 800 kPa. The refrigerant is circulated through the compressor at a rate of 0.5 kg/s and the low-temperature evaporator serves a cooling load of 10 kW. Determine the cooling rate of the high-temperature evaporator, the power required by the compressor, and the COP of the cycle. The refrigerant is saturated liquid at the exit of the condenser and saturated vapor at the exit of each evaporator, and the compressor is isentropic efficiency is 95%. 32 Condenser Evaporator 1 Pressure reducing valve 1 Evaporator 2 7 well Figure 1: Schematic diagram for task 5
