摘　　要：为充分利用再生水余热,实现燃气锅炉烟气余热深度回收,提出一种多级再生水水源热泵联合燃气锅炉供热系统。将单级再生水水源热泵联合燃气锅炉供热系统作为比较对象,分析热泵机组装机容量占比对系统经济性的影响。随着热泵机组装机容量增大,系统一次能源利用率逐渐升高。单位供热量燃料动力成本、单位供热量综合成本均随热泵机组装机容量占比增大而减小。In order to make full use of the waste heat of reclaimed water and realize the deep recovery of waste heat from flue gas in gas boilers,a combined heating system of multistage reclaimed water source heat pump and gas boiler is proposed.Taking the combined heating system of singlestage reclaimed water source heat pump and gas boiler as a comparative object,the influence of the installed capacity proportion of the heat pump unit on the economy of the system is analyzed.With the increase of the installed capacity of the heat pump unit,the primary energy utilization rate of the system gradually increases.The fuel power cost per unit heating capacity and the comprehensive cost per unit heating capacity both decrease with the increase of the installed capacity proportion of the heat pump unit.
