Abstract :This study is composed of two parts. One is the measurement results of the convective, radiant and total heat transfer coefficient, and the other is the study of condensation control technique in the case of floor cooling. Two studies are tested by the environment test chamber, which controls the each surfaces temperature of the floor, wall and ceiling, using cold and warm water radiation panel. The results of the measurement are as follows: (1) Both vertical and horizontal temperature distribution is 21-22℃ when floor heating, and the temperature distribution is uniform. (2) The temperature differences by the heating air conditioner are larger than by floor heating. (3) The radiant heat transfer of the floor is the 19.3W/m^2 in case of floor surface temperature sets 40℃, the ceiling and walls temperature set 30℃. (4) The calculating method to prevent condensation at cooling floor is made by parameters of temperature of dehumidification coil entrance water and the area of heat exchanger.
