This study is Korean traditional heating system, named 'AZABANG'. Ondol characterized by" Azabang "is dated back to 119 AD and it has approximately 2000 years history. Among various kinds of traditional radiant floor heating system, Ondol is the most reasonable and scientific one. This type of imaginative Ondol which have superior ability to keep temperature during a long period, roughly I 00 days could be attributable to the special structural pattern . The Ondol characterized by ''Azabang" represents extraordinary creativeness originated from Korean traditional culture and at the same time, it is the significant evidence that those missing historical rings, in some degree, have been connected. Therefore we well do our best to apply the scientific and reasonable concept into the real world.

Ondol, Korean traditional heating system, has widely been used due to high thermal efficency based on its character of thermal dynamics. it has been also well known Ondol has improved real indoor thermal comfort compared to the other heating systems. Recently, a lot of numerical studies using CFD(Computational Fluid Dynamics) in order to understand interal thermal and flow field has been corned out. In present study, we find out the variation of temporal temperature in floor of traditional Goodie between Jul-Gorae and Doidon-Gorae, we have performed numerical analysis. According to flow rate streams, Weet-mok's temperature in a Doidon-Gorae is 7 t:: higher than Jul-Gorae 's. This asymmetry part has an influence on decreasing a standard deviation of the temperature.

To maintain optimal performance in a floor heating system, the elements of system must be consisted of the adequate structure in order that the heat flow is efficiently transmitted from the floor structure to indoor space. The aims of this study is to propose the optimal structure type and present applicable design data of a floor heating system. The design data suggested in this study can be applied to cooperate energy efficiency design as well as comfortable indoor thermal environment in the early design stage.

This paper describes the traditional Ondol medical care, the specific combination of ancient and contemporary examples to be articulated. As a traditional Korean culture, to be extracted from the historical perspective, it described the relationship and origins between them, From a health perspective, in accordance with the logic and pharmacologyit introduced Ondol as the important principle of health care equipment. The modern architecture of some common harmful to the body, from the perspective of Ondol, it should be improved and based on scientific proof to the theory.

Ondol is the unique traditional heating system of Korea, which is excellent in thermal comfort. Whereas it has several merits as a wet construction method, its work process is complicated and disadvantageous in protecting noise and has concrete heat storage layer. So it is necessary to develop a new material to cover these demerits. In this research the material that can resolve the problems of construction and noise prevention while keeping heating function of existing wet floor structure has been developed through manufacturing artificial wooden floor panel utilizing waste tires. The developing tendency of existing floor structure companies was studied for experimental contents, and through testing of manufactured materials' degree of strength of bending and pressure the function and similarity of natural wooden material could be confirmed. These floor structure can be shortened of its construction period through simple method which results in saving construction cost and convenience of maintenance, and especially it can be said that as 70~80% of its material is powder of waste tires, it has excellent function against floor impact noise and it utilizes recycling material more than anything. It is likely that through more tests and research, the construction method for linking part between panels which hasn't been dealt with in this research will be improved.

This paper introduces the basic classification of Ondol, the number and form of main entrance, distribution as a basis for classification. And it introduces the various practices and structural characteristics of Ondol. Details are introduced in various forms Ondol of the working principle. In the paper, it also did a more detailed exposition for some of the concepts right.
