An Air Exchange Ventilator (AEV) is designed to
provide fresh air into a building while exhausting an equal amount of stale air.
During the winter months, the incoming cold fresh air is warmed by mixing it
with return air before it is supplied to the home. During the summer
months when the indoor space is air conditioned, the AEV will help in cooling
the incoming fresh air with the stale air that is being exhausted.
Fantech's AEV's are designed to run continuous
or on intermittent, giving the homeowner complete control over the air quality.
Continuous low speed ventilation is recommended, which will help eliminate
carbon dioxide, voc's and other gases as well s freshen up the home.
Intermittent high speed ventilation can be obtained through a variety of
optional remote controls. Below are some examples of seasonal operation of
an AEV:
Winter: Humidity control is very important
during the winter months. This is when problems will be most apparent
since condensation on the windows will often occur. the colder the outside
temperature, the greater the risk of condensation in the home. The average
relative humidity should be maintained (30-60) to avoid condensation. Low
speed continuous ventilation with high speed override is recommended.
Spring: Temperatures are more moderate and
become warmer each day. To keep the humidity and temperature in uniform,
set the dehumidistat higher and the switch on the AEV to standby.
Summer: The air is sometimes hot and humid.
To stop the warm humid air from entering, set the dehumidistat at its highest
level and the switch on the AEV to standby.
Fall: Rain and rapid temperature changes make it
difficult to control the internal humidity level and may result in condensation
on the windows. A remote dehumidstat may help give greater control over
the inside environment.
Sizing (Example) for maximum airflow normally
required:
AEV's are typically sized to be able to ventilate the whole house at a maximum
1/3 of an air change per hour. To calculate this simply take the square
footage of the home (including basement) multiply by the height if the ceiling
to get cubic volume, and then multiply that by .005
