摘 要: 针对不同负荷不平衡率时地下埋管换热器的传热特性展开研究,提出采用辅助冷热源、盘管排数调节等策略建议,以期土壤源热泵系统的高效运行.此外,还建议将地下埋管换热器安装在地下水丰富地区,亦可以减轻土壤全年热不平衡所带来的问题. A research is made on heat transfer characteristic of ground heat exchanger(GHE) with different heat imbalance rates,and then,the suggestions such as auxiliary cool and heat source,ground heat pipe adjustment are put forward for better and efficient operation of system.Furthermore,it is much better that installing ground heat exchanger in the area with high groundwater flowrate for the alleviation of soil heat imbalance problems.
