Experimental Study, Modelling and Design of High-Temperature Ground Thermal Energy Storage for Achieving Energy Efficient Building Energy Systems

蓄热系统是提高能源效率和节约能源的一项关键技术。它通常有助于减少系统中热能需求和供应之间的不匹配，从而提高其效率。因此，在建筑物、后院或前院下随时可用的地面热能储存（GTES）可以在未来应对气候变化、减少化石燃料消耗和提高可再生能源利用方面发挥重要作用。这项技术还可以通过区域供热系统扩展到社区，就像阿尔伯塔省奥科托克市独一无二的德雷克着陆太阳能社区一样。在这里，自2007年以来，通过回收夏季从高温（高达80°C）地面热能储存中储存的太阳能，满足了52户住宅90%的居住空间供暖需求。等效减少的热量约为39吉焦（或1,050米）

A key technology in energy efficiency and conservation is a thermal energy storage system. It often helps to reduce the mismatch between demand and supply of thermal energy in a system, thereby improving its efficiency. Thus, a ground thermal energy storage (GTES), readily available under a building, backyard or front yard, can play an important role in the future to combat climate change, reduce fossil fuel consumption, and increase renewable energy utilization. The technology can also be extended to communities through district heating systems, as is the case at the one-of-a-kind Drake Landing Solar Community in Okotoks, Alberta. Here, 90% of residential space heating needs for 52 houses have been met since 2007 by retrieving solar energy stored during the summer season from a high-temperature (up to 80°C) ground thermal energy store. The equivalent reduction is approximately 39 GJ of heating energy (or 1,050 m
