Although the B6LC and B12LC models have good ef
fi
ciencies, the supply air could be colder than the ambient r
oom air
. It is possible to eliminate the discomfort
associated with this temperatur
e dif
fer
ence by installing an electric duct heater
. This will temper the air befor
e it is distri
buted thr
oughout the building.
The tables below gives the heating r
equir
ements at dif
fer
ent temperatur
es and airfl
ows.
NOTE: The data does not r
e
fl
ect a r
eduction in ef
fectiveness due to fr
osting.
Based on the standar
d air at:
1.2 Kg/m3 and Cp = 1.0 KJ/Kg°C 13.35 lb/ft3 and Cp = .24 Btu/lbm°F
