The limitation of mini - volume and mini - power application condition is adequately considered , and design of whole refrigeration system is accomplished farther , including choose and structure design of compressor , choose and calculation of heat exchanger , calculation of capillary , etc . structure design of the rotary compressor is the most primary part of the design of whole refrigeration system
根据计算结果，并充分考虑到小体积、小功率的应用环境限制，进一步完成了整个制冷系统的设计实现，包括压缩机的选型和设计、换热器的选择和计算以及节流管的计算等等。其中，滚动转子压缩机的结构微型化设计是整个制冷系统设计的核心部分。
They will short down the working life of air compressor because they are always started or stopped when we want to make the railway carriage stay in a fixed temperature . now , automatic and intelligent control systems are being applying in bus air - conditions control . in this way , computers control the work of air compressor , the turnaround speed of fan , the open degrees of wind controlled doors and so on
我国大多数客车空调仍然采用简单的压缩机开关控制及循环离合控制系统，如：离合器?热力膨胀阀系统( cctxv )和离合器?节流管系统( ccot ) ，这些控制方式的精度低，当进行恒温控制时压缩机处于频繁的开、停状态，缩短了压缩机的工作寿命。
