基于全尺度线热源解的地热换热器集群的温度响应
Temperature responses of ground heat exchanger clusters based on full-scale line-source solution
摘要
Abstract
In order to tackle the problem of heat transfer of GHE spanning diverse time-space scales, a full-scale line-source solution was reported for heat transfer of ground heat exchanger (GHE) clusters, which was an analytical solution that was developed from the method of matched asymptotic expansions and the principle of superposition. Temperature-response curves of line- and matrix-arranged GHE clusters were presented and the impact of borehole spacing on temperature evolution in the ground was analyzed. The results show that full-scale line-source solution simplify the calculation temperature range of GHE clusters.关键词
