摘要
地埋管换热器的单位孔深换热量,由综合传热系数与可利用温差组成,利用已建工程的经验数据,得出综合传热系数。为了提高可利用温差,增加传热效果,提出华北地区"先存后取"的运行策略。
On the foundation of analyzing the unit hole depth heat transfer of ground heat exchanger, it is consist of composite heat transfer coefficient and available temperature difference. With the help of empirical data of constructed project, the composite heat transfer coefficient was driven out. In order to improve the available temperature difference and increase the efficiency of heat transfer, an ooeration strateRT in the northern areas was orooosed.
