OPERATION
The AprilAire E100 Dehumidiers are designed to dehumidify the air coming into the
unit by passing the incoming air over an evaporator coil, dropping the air temperature
below the dew point. The moisture is removed from the air and drains out of the
dehumidier to a common oor or waste drain. The air is then reheated in the
condenser coil and exits the unit.
Dehumidication occurs until the relative humidity (%RH) setting is reached. The unit
then shuts off until periodic sampling determines the need for dehumidication.
The integrated digital display and control monitors the %RH during sampling of the
incoming room or HVAC return air.
APPLICATION
AprilAire E100 Dehumidiers are the perfect product for whole-home dehumidication,
basements, crawl spaces and sealed attics.
VENTILATION
All E100 models have the ability to bring in fresh, outdoor air into the living space. Fresh
air will dilute stale air and pollutants and will reduce humidity in the winter months. If the
humidity level of the outdoor air higher than the %RH setting, the dehumidier will begin
dehumidication to reduce the humidity in the home to set humidity level. The outdoor
fresh air is brought in through 6" round duct with a 6" round, normally closed damper. This
complies with ASHRAE 62.2, Energy Star, and International Residential Code (IRC).
The dehumidier has built-in controls to adjust the amount of fresh air that is brought
in to the home. If wired to the HVAC system, the dehumidier will bring in the outdoor
air when the HVAC system calls for heating, cooling, or is running continuous fan.
If the amount of set ventilation time has not been met during the HVAC calls, the
dehumidier will open the ventilation damper and turn on the HVAC fan and bring in
fresh air until the ventilation time has been met.
High and low temperature limits are available in 3 different modes, preventing outdoor air
that is too hot or too cold from being delivered to the home. If the outdoor temperature
rises above the high limit or drops below the low limit, ventilation will not occur. If the
outdoor temperature drops below the heat only limit, ventilation will be allowed only
when the HVAC system is calling for heat. A high indoor %RH limit is also available in all
three ventilation modes.
ZONED DEHUMIDIFICATION
The E100 Dehumidiers are capable of zoned dehumidication. In this application,
the dehumidier can control the humidity in two separate zones in the home, a Primary
and Secondary Zone.
