A Study on the Driving Performance of Evaporation Pressure Parallel Control Refrigeration System by Evaporation Condition

The refrigeration system with parallel control of evaporation pressure is used to refrigerate two separate spaces with two different temperature by one compressor. This refrigeration system can be operated by accurate performing load estimation of each evaporator. The experiment was conducted to connect the general vapor compression refrigeration system to two evaporators in parallel, to attach the evaporation pressure regulator to the high temperature evaporator, and to regulate the evaporation pressure and refrigerant circulation amount once per 10%. The result of the experiment shows that refrigerant circulation amount and the variation of evaporation pressure of the high temperature evaporator has effect on the pressure and temperature of low temperature evaporator, and many effect on the COP(coefficient of performance).
