3．采用其他型式制冷循环为了避开CFC及HCFC工质对地球环境的影响,人们又开始把注意力放在蒸气压缩式以外的其他型式的制冷循环了,其中包括诸如带相变热驱动制冷循环(吸收、吸附和喷射式)、不带相变热驱动制冷循环(威勒米尔·VM制冷循环,干燥制冷、双斯特林制冷机等)以及斯 3. Other Types of Refrigeration Cycles To avoid the impact of CFCs and HCFCs on the Earth’s environment, attention has been focused on other types of refrigeration cycles besides vapor compression, including those such as phase-change thermal-driven refrigeration cycles Absorption, adsorption and injection), without phase change heat-driven refrigeration cycles (Wimmere VM refrigeration cycle, dry cooling, double Stirling refrigerators, etc.)
