大连某超低能耗别墅水平地埋管地源热泵系统应用
Application of ground-source heat pump system with horizontal ground heat exchangers to an ultra-low energy consumption villa in Dalian
摘要：
利用DeST软件对某超低能耗建筑全年负荷进行计算，建立了水平地埋管地源热泵系统数值模型，研究分析了系统的运行特性和适应性，并与竖直地埋管地源热泵系统进行对比，分析了两者的经济效益和环境效益，并将环境效益货币化，评价其综合性能。结果表明：水平地埋管地源热泵系统的占地面积、系统效率均可满足超低能耗建筑的相关要求，虽然环境效益稍差，但系统的经济性和综合效益均优于竖直地埋管系统。对于单体超低能耗建筑供能系统，水平地埋管地源热泵系统具有良好的应用前景。
Abstract：
Simulates the annual load of an ultra-low energy consumption building by DeST software. Establishes a numerical model of ground-source heat pump system with horizontal ground heat exchangers, and studies its operation characteristics and adaptability. Compares and analyses the economic and environmental benefits of horizontal and vertical systems, monetizes the environmental benefits and evaluates their comprehensive performance. The results show that the occupied area and system efficiency of horizontal system can meet the requirements of ultra-low energy consumption buildings. Although its environmental benefit is worse than that of the vertical system, the economic and comprehensive benefits of the horizontal system are better than those of the vertical system. The ground-source heat pump system with horizontal ground heat exchangers is an excellent energy supply system when it is applied to individual ultra-low energy consumption building.
