The results from a computational fluid dynamics (CFD) study on the effect of air supply diffuser type and exhaust loca-tion in a typical animal research laboratory are presented. The results show that low-level exhausts produce higher tempera-tures in the room and cages, but the best in-cage ventilation (lowest CO₂ concentrations) compared with ceiling or high-level exhausts. Further, the study shows that the slot diffuser seems least sensitive to exhaust position. Finally, the results show that the room concentrations of CO₂ and NH₃ do not show any supply type or exhaust location to be significantly better or worse than any other type.
