on Model 1200SDD
ALDES Model HRV 1200SFD or
1200SDD is a compact heat recov-
ery ventilator designed to exhaust
stale indoor air and supply fresh air
from outdoors. It is intended for
small commercial and institutional
applications, such as office build-
ings, classrooms, dormitories, res-
taurants, health clubs, etc.
It is a technically advanced con-
trolled mechanical ventilation sys-
tem to meet the requirements of
modern, tightly built and highly in-
sulated buildings. It provides a
consistent supply of fresh air while
lowering heating costs during the
winter by transferring heat from the
exhaust air to the fresh air stream.
During the summer it also reduces
the load on the air conditioner by
lowering the temperature of the
fresh outdoor air. The system pro-
vides an economical solution for
excessive indoor humidity, odors,
stuffiness, and other indoor air pol-
lutants.
As the two air streams pass through
the HRV, they are separated by thin
plates of aluminum in the core. The
air streams do not mix, so there is
no recontamination of the fresh air
by stale air. Heat passes through
the thermally conductive aluminum
from the warmer air stream to the
colder air stream, recovering most
of the energy otherwise lost to the
outdoors.
the cycle until temperatures rise
above 23 °F. The Model 1200SDD
blocks outside air during defrost
and draws indoor air through the
supply (with the same temperature
and defrost time schedule as the
fan defrost system).
The Model 1200 is available with
two defrost options. The Model
1200SFD begins the defrost cycle
at temperatures below 23 °F (-5 °C)
by shutting off the supply fan for 4-
1/2 minutes, then resumes normal
operation for 17 minutes, repeating
