小型制冷压缩机是小型制冷机的心脏。近几十年来,小型制冷压缩机的结构大约15年左右更换一次。转速也一再增加,产量也逐年增,在第二部分综述了制冷压缩机的主要型式.按电动机安装方式可以分为封闭式、半封闭式和开启式三种;按结构形式来分可以分为活塞式、回转式和螺杆式三种.按制冷剂种类可以分为氟里昂、氨、氯甲烷、二氧化硫几种。在第三部分简要介绍了主要的制冷剂的性能.在第四部分以小型制冷压缩机的典型代表—冰箱压缩机为例介绍了连杆式、滑管式、滚动活塞式三类冰箱压缩机的特点.最后介绍了目前国内外冰箱压缩机的生产情况.
Small refrigeration compressors are the heart of small refrigerators. In recent decades, the structure of small refrigeration compressors replaced about 15 years. The rotational speed also increases repeatedly, the output also increases year by year, in the second part summarizes the main types of refrigeration compressors. According to motor installation can be divided into closed, semi-closed and open three; according to the structure can be divided into points Piston, rotary and screw type 3. According to the type of refrigerant can be divided into Freon, ammonia, methyl chloride, sulfur dioxide several. The performance of the main refrigerants is briefly introduced in the third part.In the fourth part, the typical representative of a small refrigeration compressor - a refrigerator compressor is taken as an example to introduce the three types of refrigerator compressors of the connecting rod type, the slide tube type and the rolling piston type The characteristics of the compressor.Finally introduced the current domestic and foreign refrigerator compressor production.
