溴化锂吸收式制冷机在我国有了较快的发展,特别是近几年蒸汽两效及低压两效机组有一定的批量生产,应用的范围也越来越广,但这主要是数量上的增加,技术水平没有重要的突破,同国外同类产品相比,不管是设计计算、制造工艺、测试手段还是自动化控制水平等都存在很大的差距。目前,国 Lithium bromide absorption chillers have developed rapidly in China, especially in recent years, two-effect steam and low-pressure two-effect units have a certain amount of mass production, and the scope of application is also becoming wider and wider, but this is mainly an increase in quantity. There is no significant breakthrough in the level of technology. Compared with similar foreign products, there is a large gap between design calculations, manufacturing processes, test methods, and automation control levels. Currently, the country
