Now saving energy has be coming 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 temper ature 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 pro duce 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. Key words :Lithium Bromide ;Absorption Heat Pump ;Two - Stage ;Design 1 　前言
