Product Description

We came up with the idea for our Distributed Forced Air System because there are often siutations where a traditional central forced air system is too costly or obstrusive and the fact that sometimes installing many fan coils in a home can be just as costly and a lot more work to install.  The DFAS system is ideal for bungalows where up to 3.5 tons of cooling is desired, a centrally located closet exists and the attic is accessible.  The DFAS coil is installed at the top of a closet or inside an insulated enclosure in the attic with return air grills located below and to one side.  Two 3/4" insulated PEX lines are then run from the mechanical room to the coil with a third 3/4" line ran from the condensate drain to the nearest drain via a trap.  Up to five 8" insulated flex runs are connected from each take-off to a ceiling register and a DFAS in-line blower is then installed midway between the coil and each ceiling register.  Blown-in ceiing insulation then covers the 8" flex to further insulate it.  Electrical outlets are installed in the attic for each room's blower and the power is switched by relays in a cabinet which are controlled by the "Y" or cooling signal from a heat/cool thermostat.  Lastly, a current detecting relay passed over the relay panel feed acts as an end-switch for the chilled water circulator.  The end result is a zoned, variable load forced air cooling and dehumidification system that is easy to install and maintain.
