Abstract
A flow director including a diverting box defining four openings and having four baffles mounted therein. A damper is rotatable within the diverting box to provide for flow in one position between the first and fourth openings and between the second and third openings. In a second position of the damper flow is permitted only between the second and third openings. The combination of the flow director and an air treating means provides for desired flow paths of the air for heating and/or cooling purposes.
Claims2
The combination comprising:
- a furnace including a blower for moving air therethrough from an inlet to an outlet;
- a diverting box having at least first and second opposed sides, said diverting box including wall portions defining first, second, third and fourth openings arranged consecutively between the first and second sides;
- a first baffle mounted within said diverting box and extending inwardly from a wall portion between the first and second openings, said first baffle spanning between the first and second opposed sides of said diverting box;
- second, third and fourth baffles mounted within said diverting box and extending inwardly from wall portions between the second and third, third and fourth, and fourth and first openings, respectively, each of said baffles spanning between the first and second opposed sides of said diverting box;
- a damper rotatably mounted within said diverting box, said damper being rotatable about an axis extending normal to the first and second opposed sides, said first baffle extending inwardly to said damper, said damper having first and second portions extending in differing directions from said axis, said damper having a first position in which the first and second portions are adjacent said second and fourth baffles respectively, thereby permitting flow between the third and fourth openings and blocking flow between the first and second openings, said damper further having a second position in which one of the first and second portions of said damper is adjacent said third baffle, thereby permitting flow between the first and fourth openings and between the second and third openings;
- said diverting box being connected to said furnace with the inlet of said furnace communicating with the third opening of said diverting box;
- a supply air duct connected to said furnace with the outlet of said furnace communicating with said supply air duct;
- a return air duct connected to said diverting box with said return air duct communicating with the fourth opening of said diverting box;
- means for treating air, said air treating means including an inlet and an outlet;
- first connecting means for connecting the first opening of said diverting box with the inlet of said air treating means;
- and
- second connecting means for connecting the second opening of said diverting box with the outlet of said air treating means.
