A new approach on zonal modeling of indoor environment with mechanical ventilation

A new zoning approach is developed in this paper. The main issue of the new approach is that zoning should be based on the distributions of flow field and the zoning results should indicate the uniformity of zones in space.In this work, air age is adopted as a basis for zoning in mechanically ventilated rooms. For the demonstration of the applicability of that new approach for predicting indoor temperature in a displacement ventilated room, a case study is performed. Comparisons of the results with those of a CFD model are presented.
