LOCATION OF STEAM DISTRIBUTORS WITHIN AN AIR HANDLER
(1)
Humidify after the heating coil (H/C) so that absorption will occur before the
cooling coil, any excess water will be drained away. There is little chance of
condensation on the blower, blower motor, or fan isolation components,
especially if you use a modulating high limit humidistat. All steam distributors
should be a minimum of 8 in. from the heating coil and evenly spaced. If
downstream wetting is a problem, add more distributors. See Figure 15.
F.
DISTRIBUTOR ABSORPTION DISTANCE
(1)
The water vapor discharged from the steam distributor must be adequately mixed
with air to prevent condensation on downstream components. Consult the
designing engineer or refer to the NHRS Engineering Manual.
