摘　　要：地源热泵水平埋管占地面积过大一直是难以解决的问题,根据热管高效的传热特性,提出利用热管技术强化地源热泵水平埋管与深层土壤的换热效能,减少水平埋管的占地面积.根据埋管工作的温度范围,设计选择耐腐蚀的不锈钢式热管,并通过理论计算,得到热管长度与占地面积的关系.在理论可行性基础之上进行应用可行性分析,方案在保证换热量的条件下能够节省占地47%.Level buried pipe of ground source heat pump occupies too many ground, and it is a difficult problem all the time.The paper puts forward the idea of using heat pipe technique whose heat transfer efficiency is excellent to improve heat exchange efficiency between level buried pipe and deep soil in ground source heat pump system.This project can lessen occupied ground.Designing and choosing stainless steel heat pipe based on the working temperature,we can get the relation between the heat pipe length and the occupied ground through calculation.The feasibility of applicability is analysed on the basis of theoretical feasibility.The project can ensure heat exchange and decrease 47% of the occupied ground at the same time.
