Flow in the room affected by the supply air from the air-conditioner

The characteristics of the supply air flow from an air-conditioner affect to the room flow distribution. Heated air which Archimedes number is equivalent to an air-conditioner was supplied to chamber modeled of real resident space. The velocity in the flow of the model was analyzed by Particle Image Velocimetry(PIV). It became clear that the flow rose and never reached to floor in case of Archimedes number is larger than 0.02.
