WHY VARIABLE AIR VOLUME?

With the introduction of VAV systems into the air conditioning industry, a number of years ago, the idea of varying supply air volumes (at constant temperature) with room load variations, seemed to many engineers totally unacceptable. It went against all other contentions that reducing air volumes would result in insufficient room air.

And then?

Introduction of VARIABLE GEOMETRY VAV DIFFUSION EQUIPMENT! With the introduction of this equipment and design improvement to VAV systems, confidence was generated by the improved performance of the system. The world's consciousness for the need to conserve energy accelerated the tendency for designers to use VAV as the most economical and efficient solution to the problems posed by the multi-zone requirements of modern buildings. Unquestionably no other system offers such low operating costs and such flexibility in its application to multi-zone air conditioning diversities.
