Experimental Study on Miniature-Refrigeration System

摘要：

　　A prototype of miniature cooling system was developed,which mainly consists of the miniature compressor from DONG YUAN and a spiral-tube evaporator designed by ourselves.The performances of the prototype with different parameters were tested.The influence of ambient temperature,chilled water temperature on the performance of the cooling system were analyzed.The best operating conditions and the optimum amount of refrigerant were obtained.Conclusions were gotten as follows:1) With environment temperature rising,compression ratio increases,system power consumption increases and refrigerating capacity COP decreases.2) With chilled water temperature rising,compression ratio and power consumption decrease,refrigerating capacity increases,and COP increases rapidly.3) Paper gets system performance:refrigerating capacity is 63 W,compressor power consumption is 24.5 W,COP value is 2.57.in operation condition:refrigerant amount is 40g,environment temperature is 30℃,chilled water temperature is 40 ℃,chilled water mass flow is 45 kg/h.
