Location and type of ceiling registers

[robertc65]

If I had a system installed in the attic to service just the 2nd level where in the ceiling should the supply and return registers be located? Each room has a ceiling fan in the center of the ceiling, so I'm hoping the center is not the best place. Also should registers be used that will throw the air towards the windows / exterior walls?

Thanks

I'd locate them near an inside wall ,directing the air along the ceiling ,to the ouside wall that has the window,larger window,or window with the worst exposure.

I'd use the A600 series grilles.


For a room that wider then deep,with say three outside walls ,I'd use a grille that directs air three ways .

My recommendation would be to locate ceiling supplies along the interior wall of a room that is opposite but parallels the exterior wall with windows. Supply boot should be between 12" - 18" out from the wall. If only one register for the room is necessary, it can be centered near the interior wall, with register throw toward the outside wall. Adjustable curved blade registers are the best selection, especially when aimed so supply jet travels along the ceiling and does not drop significantly until it reaches the wall and windows with exterior exposure. I prefer single throw curved blade, but 2 or three way throws can be used if washing adjacent exterior walls is desired.

The important thing is to establish a total air circulation pattern in the room. To do that it is important that a sufficient return path exists between the room and the air handler/furnace. Returns should not be directly adjacent to a supply, nor should they be in the primary air jet emerging from a supply register. Locating a return along the same interior wall as the supply, set out the same distance from the wall but not directly adjacent to the supply is fine. Returns have little overall influence on air patterns other than the area they immediately draw from, and they also prevent the room from being overpressurized. They also ensure a more complete air change, which is vital for both heating and cooling functions. You can't condition air that is not returned to the air handler or furnace.

Thank you for your response. You explained it so well I have no other question at this time
