近年来,国内两级发生溴化锂吸收式制冷机的研究、试制、试验工作正在进行。但两级发生溴化锂吸收式制冷机的热力计算、特性点的选取原则等方面的资料缺乏。国外使用的图表与国产溴化锂溶液的性质又不完全一致,因而不便采用。本文系根据国产溴化锂溶液的物性图表,结合物性图表制作的方法和选用的基准,整理出适合我国情况的热力计算方法及特性点的选取原则,供参考。
In recent years, research, trial production and test work of lithium bromide absorption chiller occurring at domestic and two levels are under way. However, there is a lack of information on the thermodynamic calculation of lithium bromide absorption chillers at two levels and on the selection principle of characteristic points. The chart used abroad is not exactly the same as the nature of domestic lithium bromide solution, so it is inconvenient to adopt. This article is based on the physical properties of domestic lithium bromide chart, combined with physical chart production methods and selection criteria, sorting out the thermodynamic calculation method suitable for our situation and the characteristics of the principle of selection for reference.
