Technology and Economy of Combined Heating of Reclaimed Water Source Heat Pump and Gas Boiler
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 multi-stage reclaimed water source heat pump and gas boiler is proposed.Taking the com-bined heating system of single-stage reclaimed water source heat pump and gas boiler as a comparative ob-ject,the influence of the installed capacity proportion of the heat pump unit on the economy of the system is an-alyzed.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 in-crease of the installed capacity proportion of the heat pump unit.
