摘　　要：对热电冷联产中一种新型热回收系统——溴化锂制冷-热泵系统进行了系统设计与性能分析。该系统利用热泵回收溴化锂制冷系统的冷凝热来加热锅炉除盐水,可以减少除氧器中加热用的背压蒸汽消耗量,提高能源利用率,产生显著的节能、经济、环保效益。A new heat recovery system for LiBr refrigeration-heat pump system applied in combined cooling, heating and power system was designed, and performance analysis was given out. The system used exhaust condensing heat of lithium bromide refrigeration system recovered by heat pump to heat the demineralized water of boiler. This technology can improve energy efficiency, decrease the consumption of the back-pressure steam for heating the demineralized water, and result in significant energy-saving, economic and environmental benefits.
