Abstract
A small scale field test on snow-melting system using solar heat storage through seasons was conducted. In this system, underground water was circulating between two aquifers through heat dissipation pipe just beneath road surface. In summer, underground water was pumped up from lower aquifer, collecting solar heat during flowing in the heat dissipation pipe, and pushed into upper aquifer. In winter, underground water was pumped in the opposite direction for snow-melting. The experimental results show that this system has heat storage ability in summer and snow-melting ability of about 300 W/m2 in winter.
