AIR DISTRIBUTION
Linear slot diffusers are an integral part of the Moduline
unit. They provide excellent air distribution for the condi-
tioned space. The diffuser configuration is designed to in-
duce room air, creating continuous air motion for occupants
of the room and reasonably consistent temperatures from floor
to ceiling.
Figure 85 shows how cool primary air discharged at the
ceiling line induces room air toward the diffuser. The cool
air mixes with the room air, creating room air motion and
raising the temperature of the air descending upon the room
occupants. Figure 86 provides a typical room air distribution
pattern for 2-way blow and one-way blow Moduline units.
The upper number on the distribution pattern is the mixture
temperature; the lower number is the air velocity in ft/min.
Avariety of diffuser assemblies are available for the Modu-
line unit. Tables 18 - 20 show the standard diffusers avail-
able, which can be ordered directly from the price pages.
Tables 21-23 show the optional diffusers, which can be pro-
vided by quote control.
The difference in standard 37HS diffusers and optional 37A
diffusers is demonstrated in Fig. 87. The slot opening in the
37HS is larger than that of the 37A, reducing the net pres-
sure required from the unit and somewhat reducing the throw.
Note that the dimensions of the diffuser shown in Fig. 87
are useful when matching units or 35BD boot diffusers in
the ceiling. Certified dimension drawings are available for
these diffusers and the other optional diffusers shown in
Tables 21-23.
