摘要
在冷负荷占优地区,采用冷却塔辅助地源热泵系统(复合地源热泵系统)可以有效地缓解单一地源热泵系统长期运行所带来的土壤温升问题,目前研究较多。首先回顾了地下埋管换热器的理论模型,并对常用的六种模拟软件进行了比较。综合复合式地源热泵系统的国内外的研究现状,重点对复合地源热泵系统的运行策略进行了对比分析,并提出了新的设想,以期对复合式地源热泵系统的合理应用和科学发展提供支持。
In the cooling load dominated area,the application of hybrid ground-coupled heat pump system with cooling tower as supplement can mitigate the heat accumulation effect in the soil,which is focused on by researchers currently.In the paper,the theoretical models of ground heat exchanger is reviewed firstly and then the comparison of six commonly used simulation software.Based on current research status in China and abroad,the article focuses on the comparison analysis on operation strategy of hybrid ground-coupled heat pump with cooling tower as supplement,and then put forward new ideas.All work here is helpful to the reasonable application and scientific development of hybrid ground-coupled heat pump system.
