Cold air jets system effects on the occupied regions.

Author(s) : LI Z., CHRISTIANSON L. L., ZHIVOV A., ZHANG J. S.

Summary

From theoretical analysis, it was found that the earlier separation of the cold air jets can be avoided by using small air diffusers to increase the jet velocity. This will not increase the average velocity in the occupied regions because of the smaller amount of air used. The increased jet velocity will help diffuse the cold air in the room. The authors found that by properly sizing the diffusers, roughly the same air distribution results can be achieved with cold supply air as with conventional cooling. Theoretical analysis also shows that the momentum contributed by internal heat sources is not negligible compared to the momentum that the occupied regions receive from the jets.
