The Thermal Characteristics of Low Energy Radiant Floor Heating System
A purpose of this study is to evaluate the applicability of low temperature radiant heating system using renewable energy like solar or geo-thermal. For the low temperature radiant heating, we have developed new system in which hot water is circulated on the whole part of floor panels not just pipe line. By this whole circulation heating system, we can get the satisfactory floor surface temperature using 10℃~15℃ lower hot water temperature than that of existing radiant floor heating system. And also, the heat emission of new system shows more 50％ increased efficiency than that of the existing radiant floor heating system. Test result of new system in real building shows that it is possible to use hot water of 35℃~40℃ in existing building condition with which room temperature control, structure and heating loads are same.
