土壤源热泵与太阳能耦合系统节能效果分析——以公屋展示中心为例

Energy Saving Analysis of Ground Source Heat Pump(GSHP) Coupled with Solar Energy System in Northern China: For Public Housing Exhibition Center

土壤源热泵与太阳能耦合系统将太阳能热水系统产生的盈余热量转移至土壤源热泵系统,保证热泵机组出水水温恒定,以提高土壤源热泵机组COP,减少对土壤温度场的破坏,提高系统整体运行寿命,进而降低了项目后期运行费用。以中新天津生态城公屋展示中心项目为例,通过数学建模,对该系统应用于北方地区的节能效果进行分析和论证,得出土壤源热泵与太阳能耦合系统是一种较适宜天津生态城地区的可再生能源综合利用的系统,并为北方地区建筑利用可再生能源起到了推进和示范作用。

Ground Source Heat Pumps（GSHPs） coupled with solar energy system supplies solar hot water as auxiliary heat source for GSHP to enhance COP and avoid the damage to soil temperature field. Taking Public Housing Exhibition Center in the Sino-Singapore Eco-city of Tianjin as an example, it is concluded that GSHP coupled with solar energy system is a kind of more suitable for Sino-Singapore Ecocity of Tianjin through mathematical modeling. This project plays the role of promotion and demonstration for comprehensive utilization of renewable energy in the northern region.
