通过冷热负荷分析优化地源热泵机组的选型组合

Optimizing the Selection and Combination of Ground-source Heat Pump Units Through Cooling and Heating Load Analysis

该文对重庆地区某带恒温泳池的办公楼及文体活动楼的地埋管地源热泵系统进行了全年能耗及冷热负荷分析,并根据分析结果选择了地埋管地源热泵系统能源站的组成,即全部采用了地埋管地源热泵系统,取消了冷却塔、空气源热泵、燃气(油)热水锅炉的设置,提高了可再生能源利用比例和能源利用效率,减少了建筑运行阶段单位建筑面积碳排放量,可有效节约资源、保护环境、推进绿色建筑高质量发展、实现碳中和。

This paper analyzed the annual energy consumption and the cooling and heating load of the buried-pipe ground-source heat pump system of an office building with a heated swimming pool and a recreational and sports activities building in Chongqing and,according to the analysis results,chose the composition of the energy station of the buried-pipe ground-source heat pump system.That is,only the buried-pipe ground-source heat pump systems was adopted,and the setting of cooling towers,air-source heat pumps,and hot water boilers with fuel gas(oil)were aborted,which improves the utilization ratio and efficiency of renewable energy,reduces the carbon emission per unit building area during the building operation stage,and effectively saves resources,protects the environment,promotes the high-quality development of green buildings,with carbon neutrality realized.
