摘要
地下含水层储能已成为一项应用日益广泛的实用储能技术,可以很好的应用于大型空调项目。含水层储能系统能够跨季节利用夏季的热和冬季的冷,有效减少化石燃料的使用量进而减少对大气的污染。论述了含水层储能的基本概念、工作原理,分析了地下含水层储能技术的应用条件- 水文地质条件、回灌水水质条件,进一步提出了利用地下含水层储能技术需要解决的关键问题,包括储能流体及热前沿的形状和位置、储能位置和含水层的选择、储能过程与环境的作用、储能系统的安全性、可靠性和经济性等。地下含水层储能技术具有节能和环保的重要意义,因而它具有广阔的应用前景。
Aquifer thermal-energy storage (ATES) has become a widely-used practical energy storage technology and can be applied in large-scale air-conditioning projects. With this energy-storage system, heat stored in summer can be used for heating in winter, and cooling load stored in winter can be supplied for cooling in summer. We can thus reduce the use of fossil fuels, which leads to a reduction of CO2, SOx and NOx emissions to the atmosphere. In this paper, the fundamental concept and operation principle are depicted, and the conditions for the application of aquifer energy storage, such as the hydro-geological condition and the injected water quality, are analyzed. Furthermore, crucial problems related to the application of the technology are presented, inclusive of the shape and location of ATES liquid and the thermal front, selection of appropriate ATES location and the aquifer, interaction between the energy storage process and the environment, and security, reliability and efficiency of ATES system, etc. The aquifer thermal-energy storage technology is of great importance to energy saving and environmental protection and will find wide application in the future.
