| 摘 要： | 根据R290工质的商业冷柜的制冷需求，开发了直线压缩机样机，开展了国标工况下的制冷性能实验研究。实验结果显示，直线压缩机样机在供电电压145 V，频率70.2 Hz条件下，制冷量为604 W，制冷COP为1.42，部分负荷制冷COP会发生一定的衰减，负荷率越低衰减越大，40%制冷量时COP仅为1.02。降低供电频率导致其与固有频率的偏离增大时，制冷量和COP也出现了较大的衰减。功耗分析表明，为提高直线压缩机能效，需要从直线电机的性能系数和降低活塞与气缸配合间隙两方面同时进行优化。

| Abstract: | According to the cooling demand of commercial refrigerator, an R290 linear compressor is developed and the experimental investigation on its cooling performance is carried out. The experimental results show that cooling capacity and COP of the linear compressor are 604 W and 1.42 on the rating conditions. Its COP decreases with the decreasing of cooling capacity and the COP is just about 1.02 with 40% cooling capacity. As the power frequency is lower than the nature frequency of linear compressor, cooling capacity and COP decreases greatly. The analysis on power consumption indicates that it is necessary to enhance the linear motor performance and reduce the gap between the piston and cylinder to improve the efficiency of linear compressor. |
