Abstract
It is necessary to predict the air temperature distribution easily to calculate the accurate heat loads in large spaces. In this paper, the pattern of air temperature distribution in large spaces was considerd in applying the method in which room air was divided vertically into several air masses, and the rate of imaginary ventilation between ajacent air masses was obtained from a series of model experiments. Furthermore comparing the measured rate of imaginary ventilation in actual buildings with the rate which was calculated by using the formula derived from model experiments, it was found that there was a good agreement between the measured and calculated values.
