地下岩土蓄能过程控制模式

通过均置模式、内聚模式、间歇模式和热屏模式等四种典型模式的温变特性和温度场变化特征实验研究,对其传热特性和蓄能效能进行分析。提出了温度场形态重整控制概念,并在此基础上,通过热源负荷调控,分析蓄能体能位温度变化、分布规律、时间特性和蓄能效能等。建立了温度场形态主动控制新理念,并提出了热屏概念,为实现地下蓄能最佳效率优化奠定了理论基础。

Experimental investigation on operational modes of underground thermal energy storage

Based on the idea represented by authors to reform the ground temperature distribution configuration through controlling and allotting the load, this work focus on the experimental investigation of heat transfer in the UTES and emphasizes to research the effect, temperature potential, ground temperature variety and distribution. Four typical operational modes on the load of heat resources (boreholes of underground heat exchanger), such as equivalent mode, concentrative mode, intermittent mode and heat shield mode were studied experimentally. Thus, a new method of the higher conservation efficiency of UTES has been pursued by means of controlling every load of boreholes to enhance the practical maneuverability in UTES. The reformation of temperature distribution has been ideated and presented, and the behavior of heat shield has been found to realize a higher efficiency and establish an optimization way for UTES.
