地源热泵技术在东北寒冷地区变电站的应用

Application of Ground Source Heat Pump Technology for Substation in Cold Region of Northeast China

针对东北寒冷地区供暖时间长,供暖质量要求高的现象,介绍了地源热泵系统的基本组成,分析了东北寒冷地区变电站应用地源热泵技术的必要性,对地埋管地源热泵系统、地下水地源热泵系统和地表水地源热泵系统3种地源热泵系统进行了对比,并提出东北寒冷地区变电站采用混合式地热泵系统。

According to the phenomenon of long heating time and high heating quality requirements in cold areas in northeast China, the basic components of ground source heat pump system are introduced, and the necessity of applying ground source heat pump technology in substations in cold areas in northeast China is analyzed. This paper compares the ground source heat pump system of groundwater, ground source heat pump system of buried pipe and ground source heat pump system of surface water, and puts forward that the substation in the cold region of northeast China adopts the hybrid ground-source heat pump system.
