单、双U形管地埋管换热性能对比分析

摘要

In this paper, using the common heat transfer calculation formula about ground heat exchanger, the heat transfer performance of single and double U-tube ground heat exchanger under the same load characteristics was calculated, and the difference was analyzed. Furthermore, by calculating the heat transfer performance of single and double U-tube ground heat exchanger under different load characteristics, the difference was also pointed out.%本文利用目前较为常用的地埋管换热器传热计算公式,通过对某种负荷特征下单、双U形管地埋管换热器换热性能进行计算,分析了这2种地埋管换热器在同一负荷特征下的换热性能差异；通过对不同负荷特征下单、双U形管地埋管换热器换热性能进行计算,指出了这2种地埋管换热器在不同负荷特征下的换热性能差异.
