Mechanics of the HAE Motorless HRV
With Heat Recovery (HAE), connected to a Forced Air Heating System having a furnace circulation fan running continually and developing 1/2" of static pressure = approx. 125 CFM.
ONE CUBIC FOOT OF AIR IN = ONE CUBIC FOOT OF AIR OUT
A bathroom exhaust fan has been added and connected to the HAE with two back
draft dampers isolating the operation of either the exhaust fan or the furnace fan.
