The authors prepared a simplified model for predicting vertical temperature distribution in a large space. In this model, the space is vertically divided into a number of zones. The ascending and descending currents along the vertical wall generated by convective heat flow to the wall are evaluated. When the space is air conditioned, the path of the supply air jet and the air volume entrained from each zone are evaluated. Next, by solving the equations of air flow balance and that of heat balance in each zone, the vertical temperature distribution can be calculated. This calculation model has a useful feature that can be incorporated into dynamic thermal analysis. Describes the model and reports that results calculated using this model agree well with measured results.
