Application research on air-source heat pump combined with solar roof in residential buildings in Yangtze River Basin
摘要：
为改善长江流域居住建筑冬季室内热环境，解决供暖与节能之间的矛盾，提出了空气源热泵结合太阳能屋顶的应用方式。利用DeST软件，选取重庆、长沙、南京、上海、武汉5个代表性城市，模拟计算了多层居住建筑全年累计冷热负荷指标。依据实测数据，得到了5个城市空气源热泵系统的全年耗电量指标;利用太阳能屋顶发电量评估方法，计算了采用单结晶硅、多结晶硅、非晶硅和薄膜多晶硅电池板时，5个城市的建筑全年发电量指标。结果表明：长江流域多层居住建筑空气源热泵系统的全年用电量低于太阳能屋顶光伏发电量。空气源热泵结合太阳能屋顶是长江流域供暖建筑的节能方式之一。
Abstract：
In order to improve the indoor thermal environment of residential buildings in the Yangtze River Basin in winter and solve the contradiction between heating and energy saving, puts forward a mode of air-source heat pump combined with solar roof. Using DeST software, selects five representative cities of Chongqing, Changsha, Nanjing, Shanghai and Wuhan to simulate and calculate the annual cumulative cooling and heating load indexes of multi-storey residential buildings. According to the measured data, obtains the annual power consumption indexes of air-source heat pump systems in the five cities. Using the solar roof power generation evaluation method, calculates the annual power generation indexes of buildings in five cities using monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin film polycrystalline silicon battery plates, respectively. The results show that the annual power consumption of the air-source heat pump system in the multi-storey residential buildings in the Yangtze River Basin is lower than the solar roof photovoltaic power generation. Air-source heat pump combined with solar roof is one of the energy efficient ways for building heating in the Yangtze River Basin.
