承德地区农宅光伏-空气源热泵联合供暖技术研究

Study on the Combined Heating Technology Using Photovoltaic Systems and Air Source Heat Pumps for Rural Houses in Chengde City

近年来,由于“煤改电”增加取暖运行成本,导致北方地区“返煤”现象频发。为解决清洁取暖不可持续问题,本文提出利用光伏-空气源热泵系统实现农宅供暖的技术方案,以承德地区某农宅为例,对系统供暖耗电量、光伏系统发电量进行了模拟,对采暖电费和发电收益进行了测算,结果表明采用该系统可以实现较低的甚至零成本的采暖费用。建筑围护结构的节能性能提升后,其经济性大幅度提升,证明了该系统技术上可行,经济上合理,对于太阳能资源较好的采暖地区清洁取暖有很好的借鉴意义。

In recent years,the "return to coal" phenomenon has frequently occurred in the northern region due to the increased heating operation cost of "coal-to-electricity".To solve the problem of unsustainable clean heating,this paper proposed a technical solution for the use of a photovoltaic-air source heat pump system to achieve rural house heating.Taking a rural house in Chengde as an example,the system heating power consumption and photovoltaic system power generation were simulated.The heating electricity cost and power generation income were also calculated.The results show that the system can achieve lower or even zero-cost heating costs.After the improvement of the energy-saving performance of the building envelope,its economy is also significantly improved.This proves that the system is technically feasible and economically reasonable,and has a good reference for clean heating in heating areas with better solar energy resources.
