| 摘 要： | 着重论述了地下蓄能(UTES)技术发展现状和所面临的问题,包括传热机理的研究,复杂地下环境下不稳定传热的特性以及UTES系统的控制策略等。通过地源热泵系统的竖直钻井中传热的实验和模拟计算,对蓄能的传热作用进行了分析和探讨。结果表明蓄能改变地下蓄能体的能位,并表现为蓄能体温度和分布的变化,这种变化随时间而改变。建议通过模型分析结合实验研究来进一步完善地下蓄能研究工作,推动中国地下蓄能技术的发展。

| Abstract: | The state-of-the-art of the underground thermal energy storage(UTES) and the basic problems faced by its development in the future were summarized,including the investigation of mechanisms,the characteristics of the unsteady heat transfer in a complex underground environment,and the control strategy of the UTES system.Through the experimental investigation and the model simulation of the heat transfer in the vertical borehole heat exchanger in a ground source heat pump system,the effect of the UTES was studied.Results show that the UTES changes the energy level and the temperature distribution which are changing with time.It is suggested to further improve the investigation of the UTES by both the experiments and the modelling to promote its application for the future,especially in China. |
