Demonstration of the Snow-Melting and Economic Effects of a Snow-Melting System Using Building Waste Heat

Abstract:

This study investigated the performance and life cycle costs of a snow-melting system that employs waste heat from a building in the Matsunokitouge parking area of Takayama City, Gifu Prefecture. The average center temperature of the interlocking blocks and air temperature inside the pallets in the snowmelt area were 4.8°C and 9°C higher, respectively, than those in the non-snowmelt area during the short-term observation period. Snowmelt occurred in this system when the outdoor temperature was −2°C or higher and the snowfall rate was 2.5 cm/h or lower. The life cycle costs estimated based on the experimental results generally became lower than those of the conventional system within ten years.
