第一节蒸汽喷射制冷机的概况与特点早在二十世纪初,蒸汽喷射制冷机就已出现.自一九二○年以后,由于人们在实践中不断提高了蒸汽喷射器的效率和改进了某些部件的结构,蒸汽喷射制冷机才逐渐被人们所重视,开始应用到各工业部门,用以制取2～20℃的工业用低温水。我国从五十年代起开始研究和试制蒸汽喷射制冷机,在六十年代和七十年代纺织工业等部门在高等院校、设计单位和有关工厂的共同努力下,设计和制造了一大批蒸汽喷射制冷机以制取低温水作为空调的冷
Section 1 Overview and Features of Steam Jet Chillers Steam jet chillers have been around since the early 1900s, and since 1920 steam jet chillers have become more efficient and improved in practice Some components of the structure, steam jet chiller only gradually attention by people, began to be applied to various industrial sectors, for the preparation of 2 ~ 20 ℃ industrial low temperature water. Since the 1950s, China began to research and trial manufacture of steam jet chillers. In the 1960s and 1970s, with the joint efforts of universities, design institutes and related factories, the textile industry designed and manufactured a large number of steam jet Chiller to take low-temperature water as the air-conditioning cold
