摘要:

将常规桩与地源热泵技术结合起来形成了一种新型基桩——热交换桩。首先介绍了热交换桩的概念和工作机制,并对其进行了总结和分类。桩体中埋设换热器并与地表管路连接,通过换热器中的交换液体与桩体、桩周土-地基土及地下水系统进行热交换,形成封闭的地源热泵的地热交换器,使得热交换桩具有常规基桩和地源热泵预成孔直接埋设换热器的双重作用。最后分析了热交换桩目前国内外的应用现状,指出了实际应用关键技术问题及其研究的方向。分析后可以看出,热交换桩是一种经济、环保、节能的新技术,值得推广使用。

Abstract:

With combined conventional piles and ground source heat pump, a new type of pile, heat exchanger pile, is presented. Firstly, the concept and working mechanism of heat exchanger pile are presented; and the relevant method for classification is come up with. Loops of plastic tubes for heat exchanger are inserted into a pile, which are connected with air-conditional pipe system. The heat transfer from heat exchanger pile and the ground system takes place via fluid in heat exchangers, pile, the surrounding soil and ground water. Heat exchanger piles act as double functions, conventional pile and the borehole in ground source heat pump. Finally, the current application state of heat exchanger piles and the key issues for research on this field are described. In a word, this innovative method is significantly more cost-effective, environment-friendly and energy-saving technology, which is worth applying widely.

Key words: heat exchanger piles, ground source heat pump, thermal interaction between pile and soil, shallow geothermal energy
