摘要
滚动转子式压缩机具有效率高、零部件少、重量轻、体积小等优点 ,目前已广泛应用于小型家用空调系统中。而变频式滚动转子压缩机除以上特点外 ,还具有启动电流小、节能效果显著等优点正日益得到广泛的应用。本文通过对不同变频压缩机的实验研究 ,得出了压缩机制冷量、输入功率、性能系数等随频率的变化规律。同时还详细分析和研究了排气通道上斜切口角度对压缩机制冷量、输入功率、性能系数、排气温度等的影响 。
Rolling piston type rotary compressors are widely used in air-conditioning systems at present, for they have many advantages such as small size、light weight、high performance and fewer parts so on. In addition, other strong-points including low beginning-current and efficient energy-saving are paid more attention to. In this paper by experiment at variable speeds, the changing tendency of the refrigeration capacity, indicated power and COP was obtained. At the time Influences of cut angle in indicated power, COP and discharge temperature is studied in details, too.
