POSSIBLE APPLICATION OF DAM LAKE AS A SEASONAL SOLAR ENERGY STORAGE

摘要

For promoting efficient use of energy, a new concept is required that society can choose to make a positive approach toward a solar energy based rural community which maximizes harmony with nature. This basic concept lead to a new proposal of a system to use a water storage over the four seasons: a system which uses a water lake as a thermal energy storage. Thermocline measurements were made at the Uchikawa Dam Lake located in Kanazawa, Ishikawa, Japan to evaluate several kind of exergy contents as a new energy supply potential. The data indicated that ihe system could be developed with full potential as a seasonal energy storage to be used for mostly regional cooling. This concept seems interesting to invite internationally an energy efficient society to be employed in LDCs as well as in developed countries.
