Thermal mixing of two air streams (outdoor air flow and return air flow) with different temperatures and velocities was studied experimentally in a chamber as it exists inside air handling units, with different adjustments of parallel air dampers. Results show how and where the mixing occurs in the chamber. Indications about the influence of the air dampers adjustment on mixing effectiveness are given.
