Abstract
Multiple methods of supplying conditioned air to a room and components therefor are provided. A dual plenum system has a supply plenum for delivering supply air to the room and a return plenum for returning room air to an air handling unit. Conduits are provided to permit passage of the return air through the supply plenum without breaching the integrity of the supply plenum. Modular units permit a user to customize the supply and return apparatuses. A terminal unit having a controllable damper blade can be applied to a diffuser to permit the unit to be convertible between a constant volume unit and a variable volume unit. A thermostat generates signals that open and close the damper blade at determined intervals.
Claims23
A method for delivering conditioned air to a room having a space located above a ceiling overlying the room, said method comprising:
- separating said space into a supply plenum and a return plenum, said supply and return plenums together occupying a substantial portion of the volume of said space and being located generally one above the other;
- delivering conditioned air to said supply plenum;
- discharging the conditioned air from said supply plenum into the room;
- directing return air from the room into said return plenum;
- and
- discharging the return air from said return plenum.
A method for delivering conditioned air to a room having a supply plenum located above a ceiling overlying the room, said method comprising the steps of:
- supplying conditioned air to said supply plenum at a pressure of approximately zero;
- sensing a temperature condition in the room;
- forcing air out of said supply plenum into the room when said temperature condition satisfies a selected condition;
- and
- directing return air out of the room at substantially the same volume rate as air is forced into the room.
Apparatus for delivering conditioned air to a room having a ceiling and a space above the ceiling, said apparatus comprising:
- a supply plenum in said space;
- a return plenum in said space, said supply plenum and said return plenum together occupying a substantial portion of said space;
- a source of conditioned air connected with said supply plenum to deliver conditioner air thereto;
- an air register in the ceiling arranged to direct conditioned air into the room from said supply plenum;
- and
- a return air path extending from the room to said return plenum to direct return air to said return plenum.
