Induction could be one approach. This could consist
of a small diameter High - Velocity primary underfloor
Supply air duct carrying conditioned air to sets of
nozzles along it's length. The High velocity primary air
leaving the nozzles inducing a flow of and mixing with
return air. The mixed air would then enter a conditioned
space 6 to 8 feet above the floor. Static convection and
stratification would then cause the air above this level to
rise and leave through ceiling vents.
However a more logical approach would be to use bus
or Coach type Roof mounted air conditioning units
spaced at appropriate distances along the roof. Carrier,
Mitsubishi or Thermoking can supply these.
