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.
