Abstract
In the public bath facilities "Yudokoro-Hana Yuzuki", the system recovering the substation waste heat and public bath drain water heat as unutilized energy is adopted for hot water supply and snow melting. As a result of the evaluation based on the annual operating data, it was shown that the substation waste heat recovery efficiency was 38.2%, and that the quantity of the substation waste heat recovery and the quantity of the warm drain water heat recovery accounted for 17.0% and 18.2%, respectively, of the heat demand for hot water supply and snow melting.
