The purposes of this study are to clarify properties of air temperature distribution and supply heat energy during heating in air-conditioned space and establish the methods for evaluation of them. We firstly proposed five in dices which evaluated the effects of the temperature distribution on the room heat load and the thermal comfort of occupant etc. and a index which was defined as a ratio of the amount of heat energy supplied by the airconditioning system to one calculated by the heat load estimation. We carried out many kinds of heating experiments at the full scale test room where the various types of air diffusion systems were applied. The results are summarized as follows : 1) Large temperature gradients tend to be generated in vertical direction of the room, while temperature variation in horizontal one are small. 2) Archimedean number of discharged warm air has great influence on the space air temperature distribution. The vertical temperature gradient becomes large as the Archimedean number increases. 3) The multidimensional equations to calculate the above-stated indices were derived by using the multiple regression analyses of all experimental data. These equations consist of many experimental variables such as type of supply outlet, air change rate of the room, temperature difference between supply outlet and return intake, depth of the room and location of thermostat.
