Thermal Analyses of Aquifer Energy Storage Systems

摘要

Aquifers, which are geological formations containing groundwater, offer a simple and potential way of storing heat for long periods of time. The storage medium in aquifers consists of water saturated gravel or sand. Being a natural formation, the storage volume already exists, and all that one has to do is to provide some means of transferring heat into and from the storage. Large storage volumes are also available, typical aquifer sizes ranging from hundreds of thousands to millions of cubic meters.
