前言 变容式压缩机是一种新型压缩机,它和变容式膨胀器组合为压缩—膨胀器,应用在美国七十年代发展的变容式空气制冷机和混合工质制冷机中。因为其压缩效率可达95％以上,使变容式空气制冷机的实际制冷系数高于涡轮式空气制冷机;混合工质制冷机(空气和水)的制冷系数在相当宽的温度范围内高于蒸汽压缩式制冷机。应用于蒸汽压缩式制冷机中的变容式压缩机,全效率可达到80％以上。根据计算,排气压力为7kg/cm~2(表)时,变容式空
Introduction Varactor compressor is a new type of compressor, it is combined with the varactor expander compression - expander, used in the United States in the 1970s development of variable-capacity air-cooled and mixed refrigerant refrigerators. Because of its compression efficiency of up to 95% or more, the actual cooling coefficient of the variable-capacity air-cooled chiller is higher than that of the turbo-air chiller; the refrigerant coefficient of the mixed refrigerant chiller (air and water) is high over a wide temperature range In the vapor compression refrigerator. Vaporizer used in vapor compression refrigeration compressor, full efficiency can reach more than 80%. According to calculation, the exhaust pressure of 7kg / cm ~ 2 (table), variable capacity empty
