利用东元电机研制的微型压缩机和自发研制的螺旋管式蒸发器搭建了微型制冷系统性能测试试验台,进行了不同工况下微型制冷系统的性能测试。同时分析了环境温度、冷冻水温度、冷冻水质量流量对制冷系统性能的影响规律,得出了系统运行的最佳制冷剂充注量和最佳运行工况。 The miniature refrigeration system performance test bench was built by using the miniature compressor developed by TECO Motor and the spiral pipe evaporator developed spontaneously. The performance of miniature refrigeration system under different operating conditions was tested. At the same time, the influences of ambient temperature, chilled water temperature and chilled water mass flow on the performance of the refrigeration system were analyzed. The optimal refrigerant charge and the optimal operating conditions were obtained.
