The flowfield and performance of a centrifugal compressor was predicted and analysed, which was composed of a Krain's impeller and two types of vaneless diffuser specially: one was constant area vaneless diffuser and the other was the straight-wall. The results show that the efficiency of the straight-wall vaneless diffuser is obviously lower than that of the constant area, and a separate flow occurs nearby the exit of the centrifugal impeller with the straight-wall diffuser. However, the type of vaneless diffuser has little influence on the aerodynamics performance of the centrifugal impeller. Finally, it is suggested that the constant-area vaneless diffuser should be selected as the downstream extended area of the centrifugal impeller during the prediction for the centrifugal impeller.

对Krain叶轮后带等面积与直壁两种形式的无叶扩压器离心压缩机内部流场进行了计算与分析，结果表明：直壁型无叶扩压器离心压缩机的效率低于等面积无叶扩压器离心压缩机的效率；直壁型无叶扩压器使得叶轮出口的流动出现分离；扩压器的形式对离心叶轮的整体气动性能影响并不大；在进行离心叶轮数值研究时，叶轮后的延伸区最好采用等面积无叶扩压器，以尽量减小无叶扩压器所引起的计算误差。

The atomizing set takes advantage of the condensing water and external water, and atomizes them and sprays them to the surface of the condenser and refrigerator to degrade the condensing temperature and pressure, The system changes the single wind-cooling into mixed-cooling and tremendiously degrades the condensing temperature and pressure, decreases the high and low differential pressure of compressor, degrades frequent startup and operation is difficult.

空调雾化器该雾化节能装置是利用冷凝水或经过水处理后的外接水将其雾化，并将水雾喷洒到空调器或冷库冷凝器表面，使空调器或冷库单一的风冷变成风冷和雾化水冷却的混合式冷却，从而大大降低冷凝器的冷凝温度和冷凝压力，减少压缩机的高低压差，降低了压缩机由于高温保护造成跳机频繁或启动困难的现象，不仅增加了压缩机使用寿命，而且对空调器有显著的节能效果——制冷量增加，输入功率减少。
