Benefits of technology

[0012](2) improved air distribution over the set of venturi nozzles between the plenum and the air mixing chamber;
[0013](3) improved air distribution within the unitary air mixing chamber;
[0016](6) increased flexibility in dimensioning the unit to fit in a required space and still provide a required airflow (for example, trading off the vertical dimension against foot print size);
[0019](9) improved air flow rate, improved air flow per unit of foot print area and improved air flow per unit of device volume;

Problems solved by technology

For example, some or all of the discussed publications may not be sufficiently early in time, may not reflect subject matter developed early enough in time and / or may not be sufficiently enabling so as to amount to prior art for patent law purposes.

Embodiment Construction

[0051]Discussion will begin with a couple of simplified, not necessarily preferred embodiments of the present invention (shown in FIGS. 23-26) to illustrate some of the inventive concepts. Discussion will then proceed to a couple of preferred embodiments (shown in FIGS. 2 to 22).

[0052]FIGS. 23a and 23b show ventilation system 400 according to the present invention, including: unitary plenum portion 404; heating / cooling unit 406; drainage base 407; mixing chamber outer wall 409; and venturi nozzles 416. Primary air P is blown into the unitary plenum portion from a primary air source (see DEFINITIONS section). The primary air is then forced through the nozzles 416 and down into the mixing chamber 406. Although only two nozzles are shown in FIGS. 23a and 23b, it is highly preferred that more nozzles be provided so that one or more rows of nozzles extend at least substantially all the way around the perimeter of system 400. In this embodiment, the mixing chamber is defined by the mixing...

Abstract

The present invention is directed to a 360 degree ventilation system with a single unitary plenum. The present invention is also directed to a 360 degree ventilation system with a single mixing chamber extending at least substantially entirely around the perimeter of the blow ventilation system. The present invention is also directed to a 360 degree ventilation system with a heating / cooling units that extend substantially all the way around the perimeter of the ventilation system. The present invention is also directed to a 360 degree ventilation system with a single return air chamber.

Description

RELATED APPLICATION[0001]The present application claims priority to U.S. provisional patent application No. 61 / 045,462, filed on Apr. 16, 2008; all of the foregoing patent-related document(s) are hereby incorporated by reference herein in their respective entirety(ies).FIELD OF THE INVENTION[0002]The The present invention relates to ventilation systems and more particularly a four way blow ventilation systems located between a drop ceiling and a structural ceiling of a building.DESCRIPTION OF THE RELATED ART[0003]FIGS. 1a and 1b show a conventional four way blow ventilation system 100 for installation and use between a drop ceiling and a structural ceiling of a building. System 100 includes four separate induction units 102a, 102b, 102c, 10d. Each induction unit includes: a plenum 104; a heating / cooling unit 106; a drainage base 107; a mixing chamber outer wall 109; and nozzles 116. The induction unit mixes return air (shown by arrow R) from the building with primary air (shown by a...
