摘要
在小型制冷系统中，转子式压缩机的制冷效果不及往复式压缩机，因而限制了转子式压缩机的推广应用。利用作者研制的起动电流测试装置，对不同结构的小型压缩机的瞬态起动特性进行了实验研究，提出了阻止工质在停机后的质量迁移来提高转子式压缩机制冷效果的观点．并进行了压差起动可靠性试验。本研究工作为转子式压缩机在小型制冷系统上的推广应用提供了理论依据。
The performance of rotary compressor is not better than that of the piston displacement compressor in the small refrigeration system.The measuring equipment of starting current is used to test the instanta-neous starting characteristics of various structures of small compsessors. According to the experimental studies,one point of view about preventing the refrigerant from migration for the better performance of rotary com-pressor is put forward and verified,This paper sets up,The theory base for the furthur application of rotary compressors in the small refrigera-tion system.
