各种制冷剂的演化和比较人们为了获得更好的温度条件,得到更佳的制冷循环性能,特别是为了保证用户和公众的安全,发明了卤化物制冷剂(含有CL和F的碳氢化合物),卤化物替代了原有的“自然工质”制冷剂。事实证明,卤代烃制冷剂非常可靠,人们已经满意使用了60多年(上一代制冷剂仅有
Evolution and comparison of various refrigerants In order to obtain better temperature conditions and better refrigeration cycle performance, especially for the sake of the safety of the users and the public, people have invented halogenated refrigerants (hydrocarbons containing CL and F ), Halides replaced the original “natural refrigerant”. Halocarbon refrigerants proved to be very reliable, people have been satisfied with the use of more than 60 years (only the previous generation of refrigerants
