영문 초록

This study aims to evaluate the heat transfer characteristics and energy consumption in the wet and dry ondol systems. Conditions of the continued heating mode set the room temperature at 20℃ and hot water supply temperature at 60℃ and 70℃ for 3 days. The scheduled heating mode operates heating at 6～9am (room temperature at 20℃), suspends heating at 9～18pm (leaving mode), and runs heating at 1 8~24am (room temperature at 20℃) and 24～6am (room temperature at 17℃) for 2 days. The results from the continued heating mode in the dry/wet ondol systems confirmed that the dry and wet systems had the same average indoor temperature (18.9℃) and similar energy consumption. In addition, the results from the scheduled heating mode in the dry/wet ondol systems confirmed that the dry ondol system had lower energy consumption than the wet ondol system. Therefore, the scheduled heating mode in the dry ondol system is expected to reduce energy consumption.
