季節間蓄熱融雪システム簡易設計手法の研究

抄録

This is a report on a study of simple design method for the snow melting system where geothermal energy is transported from underground to road surface by circulating water in winter, while solar heat is collected on road surface and stored into underground in summer. This system showed enough heat storage and snow melting power for road surface area of several thousand m² order, and also demonstrated good long-term reliability. Through numerical simulations of this system, the non-dimensional correlation for many system parameters was derived, which shows possibility of simplification of evaluation process for system performance.
