溴化锂两级高温吸收式热泵及其设计

Lithium Bromide Two-Stage Absorption Heat Pump and Its Design

能源问题是各国都非常关注的问题,节约能源非常重要。一些工业过程排放出大量的气体、蒸汽或热水中含有大量的余热。它们的排放,不仅造成环境的污染,而且浪费了能源。回收其中的余热显得尤为重要。溴化锂两级高温吸收式热泵是一种热升温机,它能利用70～100℃余热本身驱动,生产100～160℃的热水或蒸汽以供工业生产使用。文中介绍了两级溴化锂高温吸收式热泵的原理,对它的设计、性能等进行了分析。

The energy problem is one that every country is paying much more attention to.Now saving energy has becoming more and more important.Some industrial installs release some gas,steam or water that contain some waste heat.If they are released to the nature world,they will make thermal pollution to the environment,which we live in.The two stage lithium bromide absorption heat pump is one kind of absorption heat transformer,which can raise the temperature of the waste heat.Thus,the hot water or steam generated from the waste heat is applied in industrial process or daily use.The two stage lithium bromide absorption heat pump can be powered by the 70～100℃ waste heat,and produce 130～140℃ hot water or steam.In the paper,the two stage lithium bromide absorption heat pump is introduced,its design,performance and efficiency of the heat pump are analyzed,at the end of the paper some conclusions are given out.
