Floor radiant heating of warm water is a newly developed type of heating technology, which is energy saving, comfortable and sanitary. With the living standard improved, people pay more attention to the living quality and living environment. This type of heating method in some degree satisfies such need. As the most commonly used way of floor heating, it is installed under the floor with heating pipes, and supplied the 35℃to 55℃warm water in those pipes and released the heat flux to the inside room finally. Along with the wide use of this method, the floor heating technology develops rapidly and engineers get more familiar with this system's characteristics. That is the reason why this heating method is applied gradually to other kind of buildings, which origins from house heating.This paper starts from the application of this system in natatorium. Gained that radiated heat amount from the pool surface affects the floor surface heat radiation by analyzing the data. In consideration of these information, the heat model is established and setted up the foundation for heat calculation.Based on the established heating mathematical model, the computational fluid dynamics software FLUENT is used to calculate the floor surface heat radiation amount in condition of different floor materials, different floor structures and different boundary conditions. Those results are directly available to engineers. By analyzing the results, gained the relationship between the floor factors and heat amount coming off from floor surface, and followed experiment can validate the model of numerical calculation and calculation results. Upon this, the orthogonal trial is applied to judge the effects and salience of different factors on surface heat spread.Through the heat amount radiated from floor surface, the heat transfer expressions is used to figure out the floor effective thermal resistance under different situations. By academic analysis and educing, in combination with the form of thermal resistance, the software of STATISTICA is used to fit the calculation formula of effective thermal resistance. Consequently there comes a imple engineering method...
