建筑供暖（热水）所需的能量日益递增，而常规的太阳能热水系统和技术，其节能潜力仍然很低。为了更好地利用太阳能，增加其在建筑供暖中的比例，有必要采用可长期蓄储太阳能的装置──地下含水层蓄能装置。利用它，可将夏季太阳能集热器收集到的多余热量蓄储起来，在冬季，再提取蓄存热量来供暖供热。本文介绍了系统的相关概念、分类及优势所在，例举了一个地坑式砾石／水蓄能的太阳能供热系统，该系统能够提供４５％的全年能量需求，即可以节省５５２ＭＷｈ／ａ的燃料能源。
The amount of energy required to heat buildings (hot water) is on the rise, while conventional solar hot water systems and technologies have low potential for energy savings. In order to make better use of solar energy and increase its proportion in building heating, it is necessary to adopt a device capable of storing solar energy for a long time, namely, an underground aquifer energy storage device. Use it, the summer solar collectors can collect the excess heat stored in the winter, then extract the stored heat to heating and heating. This article introduces the concepts, classifications, and benefits of the system, and illustrates a pit-gravel / water-storage solar heating system that provides 45% of annual energy requirements, saving 552MWh / a Fuel energy.
