Analysis of metabolic CO2 concentration field in a small mechanically ventilated occupied enclosure

Abstract

The paper presents results from CFD simulations, which aim to provide the best air distribution in a small climate chamber. Inside the climate chamber, the target volume, an exposure box, is placed. Two different ventilation approaches were tested ("diffusion ceiling" and "diffusion floor") with 27 cases simulation cases altogether. The results obtained allow to assess the best case, which is further used for the building of both the climate chamber and the exposure box.
