Abstract |
The aim of the research was to develop the double floor Ondol system. Experiment on radiant property, distribution of surface temperature, insulating ability for wet hydronic Ondol and double floor hydronic Ondol system was undertaken through physical experiments in a laboratory setting. Hot water whose temperature was varied from 40??to 60??with 10??interval was supplied to each Ondol system. As a result, (1) As for the heat loss from the floor to the underground, the Hydronic Radiant Floor Heating System with Dry Double Floorings was lower than the typical Ondol system. (2)??Under consideration of the differences from supply water temperature to return water temperature, Hydronic Radiant Floor Heating System with the Double Floorings was higher than the??typical Ondol system by 0.23??to 0.62??with regard to the heat storage of the Ondol structure. (3) When supplying the 60??hot water, heat radiation efficiency of the Hydronic Radiant Floor Heating System with the Double Floorings was higher than the typical Ondol system by 9.4% with regard to the heat storage of the Ondol structure. |
