地下同轴套管式换热器取热工况热响应实验分析

Experimental Research on Thermal Response of Taking Heat Conditions of Coaxial Casing-shaped Heat Exchanger

摘要:

地源热泵系统凭借其节能和环保的特性，一经问世就迅速吸引了全世界的目光，成为了一个非常热门的研究课题。换热器的传热效率一直是地源热泵技术研究的主要问题之一，通过对比传统的单U型换热器，对新型的同轴套管型换热器的取热工况进行试验研究，并对采集的数据进行分析讨论，说明其具有良好的传热效果。

Abstract:

Ground-coupled heat pump systems quickly attract attention in the world by the advantages of energy saving and no-pollution to the environment as a hot research topic. The efficiency heat exchanger of the heat transfer is always one of the main problems of the ground source heat pump technology research. Comparing with the traditional single U-shaped, the taking heat conditions of coaxial casing-shaped were also studied, and the experimental study of the collected data were discussed which explained good heat transfer effect.
