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 refrigeration 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 temperature 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 significant.
