| 摘 要： | 对于采用地源热泵系统的以冷负荷为主的商业性建筑,因夏季冷负荷大于冬季热负荷,地下埋管年排热量大于年吸热量,若完全依靠地源热泵来供冷,则会造成埋管换热器换热能力下降和热泵机组的初投资比较高,热泵系统的循环效率也会降低。采用辅助冷却复合地源热泵系统,可有效降低系统投资,提高系统的运行节能效果。本文对复合地源热泵垂直理管换热器的换热能力进行研究以及周围土壤温度的变化进行分析。

| Abstract: | For the Cooling-dominated commercial building served by Ground-Source Heat Pump （GSHP）, generally, heat elimination more than heat absorbability at underground pipe heat exchang- er in the annual cycle. If the cooling only depends on the ground-source heat pump, it will lead to decline of the capability of the underground heat exchanger, a relatively high initial investment on heat pump, and the inefficiency of heat pump systems. In this paper, an experiment system of HGSHP is introduced. HGSHP can effectively reduce the system investment and improve the energy savings of operation system. Experiment results analysis is conducted the capability of HGSHP Vertical borehole ground-coupled heat exchanger and the change of the surrounding soil temperature of HGSHP system. |
