AirScape Residential Economizer

The AirScape residential economizer supplies the home’s central air conditioner with outdoor air whenever doing so would be more efficient than conditioning recirculated indoor air, substantially reducing household cooling expenses.

The economizer's straightforward, packaged design makes installation a breeze. The unit, which fits between 24" on-center framing, is positioned over the home's central air return and "upstream" of the air handler and cooling coil. Wiring connections are made to an outdoor and indoor temperature sensor, and to the home's thermstat. The economizer can be used with any thermostat.

  • Compatible with all residential thermostats and condensing units.
  • Installs easily on 24" O/C framing; prewired with indoor and outdoor air temperature sensors, as well as a 10' power cord.
  • Design of unit includes repositionable flanges for round 18" duct connections, a relief damper, and a 18" × 24" × 2" MERV-8 filter.

#1 Q:   My 3000SF rancher has two returns. Will I need one for each return and operate in tandem? Can I install it in just one return?
A:   If you install just one, you will only get half the effect because only half the air will be outside and the rest will be return air via the other return. Ideally you want each return to have an economizer.

#2 Q:   Do you have different size models?
A:   Only the 1 size for now. Sorry.

#3 Q:   When you want to run 100% OSA do you shift to fan only so that the condenser isnt running?
A:   You can certainly do that. Typically these are run independent of the thermostat setting. If the condenser runs the cool outside air will reduce the cooling load.

#4 Q:   If the economizer opens whenever it is cooler outdoors than in, does that mean Humidity is not taken into consideration at all?Regarding the barometric relief damper to allow indoor air to escape into the attic, can this be ducted to a louver if locating this unit in a non-ventilated plenum space?
A:   This is primarily meant as a west coast product. It is strictly temperature control and does not look at enthalpy. You could technically duct the relief but it is not advised as the pressure drop of the duct and the louver would lower hinder the barometric relief.
