A type of dynamic calculation of indoor temperature distributions.

The requirements to know indoor thermal comfort ask for a more detailed study of room temperature responses. Although CFO (Computational Fluid Dynamics) techniques can be applied successfully to the prediction of indoor temperature distributions, using them for the dynamic calculation of temperatures and air flows is still a very expensive expenditure. For indoor climate control systems, it is necessary to make quick calculations of the dynamic temperature distributions in a room. To compromise, we are trying to use a limited number of fixed air flow patterns to perform the dynamic calculations. Some of our initial study results are presented in this paper. For a typical heating situation, the dynamic indoor temperature distributions can be calculated satisfactorily with only one fixed air flow pattern. Further study indicates that when the heating power has changed, this flow pattern can be used once again for the dynamic calculations of air temperature responses.
