提出了一种热泵-冷热电联产余热回收系统,该系统回收利用溴化锂制冷系统的冷凝热加热锅炉除盐水,以减少进入除氧器的背压蒸汽量.试验研究结果表明：热泵系统性能系数(COPP)高达6．13,此时锅炉除盐水出口温度为67．8℃；热泵-冷热电联供方式比热电联供＋电制冷分产方式的一次能耗节约26．61％,节能效果显著.%A new heat recovery system applying heat pump system in combined cooling,heating and power system (CCHP)was proposed.The system can recover the heat of the LiBr refrigera-tion cooling water to heat the demineralized water of the boiler,thus to reduce the back pressure steam entering the deaerator.Experimental research on this system shows that,when outlet tem-perature of the demineralized water is 67.8 ℃,coefficient of performance (COP)of the heat pump system reaches up to 6.13,and the primary energy consumption of the heat pump-CCHP system is 26.61% lower than that of the combined heat and power production system (CHP)combing with electricity-driven refrigeration,indicating the energy saving effect of the new system is sig-nificant.
