项目摘要

An experimental study of thermal energy storage systems utilizing an aquifer has been conducted for 3 years, with the aim of securing a heat source for the purpose of space heating and snow melting energy in the Sea of Japan districts, where heavy snow fall of more than 1.5m occurs. The main objectives of our investigation are composed with 5 compornent studies, 1) The fundimental investigation of the aquifer thermal energy storage method. 2) An investigation of the complex use of solar colectors which are used in all seasons. 3) Space heating and space cooling with the stored water. 4) Investigation of the heat sources in the districts where heavy snow falls. 5) Investigation of the co-efficient of performance and the economic feasibility study of the system.The experimental results showed that: 1. A fundamental technique acheaving the thermal energy recovery factor 60% has been established. We confirmed that there was no thermal pollution and chemical pollution in the ground water by the use of the closed system. 2. Multi-purpose solar collectors, road type, roof type and river type collector, were proposed which act as warm energy collector(cooler) in summer and cool energy collector(snow melter) in winter, which enable us to utillize many kinds of energy sources. 3. By a contiunous circulation method through the tubes which were laid under the ground, the stored lukewarm water of 23.2 ゜ C resulted in base temperature of 14゜ C for space heating, and coupled short term thermal storage effect of the ground soil, sufficient energy for all winter snow melting purposes was obtained. 4. Combinning the aquifer thermal energy storage system with the co-generation system, the fuel consumption was estimated to be reduced to 1/4 of the conventional system.

一项利用含水层的热能储存系统的实验研究已经进行了3年，目的是确保日本海地区的空间加热和融雪能源的热源，那里的大雪超过1.5米。本课题的主要研究内容包括五个方面：1）含水层储能方法的基础研究; 2)一年四季使用的太阳集热器的综合使用调查。3)空间加热和空间冷却与储存的水。4)大雪福尔斯地区的热源调查。5)对系统的性能系数进行了研究，并对系统的经济可行性进行了研究。建立了热能回收率达60%的基本技术。我们证实，有没有热污染和化学污染的地下水通过使用封闭系统。2.提出了道路式、屋顶式和河流式多用途太阳能集热器，夏季集热（冷却），冬季集冷（融雪），可综合利用多种能源。3.通过地下管道连续循环的方式，储存的23.2摄氏度温水使空间供暖的基础温度达到14摄氏度，再加上地面土壤的短期储热效应，获得了足够满足整个冬季融雪目的的能量。4.含水层热能储存系统与热电联供系统相结合，燃料消耗预计可减少至传统系统的1/4。
