有了足够的蓄热能力，在夏季炎热和冬季寒冷的地区，只需少量的燃料或电力输入就可以满足所有空调和供暖要求。大多数建筑都有大量的地质材料来满足储存容量的需求，但使用季节性能源的障碍是一种有效且廉价的方式来向土壤传递热量。智能热虹吸阵列（STA）是一种满足这些热和经济基准的方法。STA使用标准被动热虹吸机制将能量从土壤中转移出去，并使用标准机械控制能量向土壤中的转移速率。在本文中，我们描述了STA如何提供季节性储能，以满足所有气候控制需求。土壤冻结的被动模式与泵- 对空调辅助运行进行了建模，并给出了仿真结果。与传统的垂直钻孔换热器相比，模拟表明，使用STA可以在40%的深度下获得相同的总传热，每段钻孔的钻井成本低一个数量级。实验室规模的智能热虹吸管实验结果表明，温度均匀，热虹吸管内壁可以保持热通量。这使得热传递率显著提高。首个用于季节性地下热能储存（UTES）的智能热虹吸装置的中试规模安装已经证明了使用廉价的直接推送技术安装该装置的能力。数据显示地下有冻土。引文:内华达州拉斯维加斯ASHRAE Transactions第117卷第1部分

With sufficient thermal storage capacity, it is feasible to meet all air-conditioning and heating requirements with a trivial fuel or electrical input in regions with hot summers and cold winters. Most buildings have available a large quantity of geologic material to satisfy the storage capacity needs, but the obstacle to using seasonal energy is an effective and inexpensive way to transfer heat to and from the soil.Smart thermosiphon arrays (STAs) are a way to meet those thermal and economic benchmarks. STAs use standard passive thermosiphon mechanisms to transfer energy out of soil, and controlled rate transfer of energy into the soil using standard machinery. In this paper, we describe how STAs can provide seasonal energy storage to meet all climate control needs. The passive mode of soil freezing and the pump-assisted operation of air conditioning are modeled, and the resultant simulations are shown. When compared with conventional vertical borehole exchangers, simulations show the same total heat transfer can be obtained with 40% of the depth using STAs with drilling costs per length of borehole an order of magnitude lower.Results of lab-scale smart thermosiphon experiments demonstrate uniform temperatures, and heat fluxes can be maintained on the inside wall of the thermosiphon pipe. This allows for dramatic enhancements of heat transfer rates. The first pilot-scale installation of smart thermosiphons for seasonal Underground Thermal Energy Storage (UTES) has demonstrated the ability to install the devices using inexpensive direct push techniques. Data indicate frozen ground in the subsurface.
