新型空气源热泵蓄热供暖系统经济性分析

Economic Analysis of a Novel Air-Source Heat Pump Heating System with an Energy Storage Tank

针对目前空气源热泵在传统除霜方式下不能持续供暖并在供暖季产生高额费用的问题,本文提出了一种新型空气源热泵蓄热供暖系统。利用Trnsys软件建立了仿真模型,针对西安某130 m2的小型别墅建筑,分析了该系统的运行情况,以及不同补贴政策下的投资回收年限,结论可供政府决策者和设计人员参考。

Aiming at the problem that the current air source heat pump can not be continuously heated under the traditional defrosting mode and generate high cost in the heating season, this paper proposes a new air source heat pump heating system with an energy storage tank. The simulation model was built by using Trnsys, and the operation of the system was analyzed for a 130m^2 villa building in Xi’an. The operation of the system and the investment recovery period under different subsidy policies are analyzed, and the conclusions can be used for reference by government decision makers and designers.
