Fan array fan section in air-handling systems

1. A fan array fan section in air-handling compartment which is part of an air-handling for conditioning the air of a structure, said fan array fan section comprising:

(a) a plurality of fans units;

(b) said plurality of fan units arranged in a fan array;

(c) each of said plurality of fans units positioned within a fan unit chamber/cell;

(d) each fan unit chamber/cell having at least one acoustically absorptive insulation surfaces;

(e) said insulation surface of said fan unit chamber/cells together form a co-planar silencer; wherein

(f) each of said plurality of fan units is suspended within a fan unit chamber/cell such that there is an air relief passage which is isolated from the remainder of said fan unit chamber/cells so that a portion of the air drawn by said fan unit passed through said air relief passage without passing through said fan unit.

2. A fan array section in an air-handling compartment which is part of an air-handling system for conditioning the air of a structure, said fan array fan section comprising:

(a) a plurality of fans units;

(b) said plurality of fan units arranged in a fan array;

(c) each of said plurality of fans units positioned within a fan unit chamber/cell which substantially surrounds said fan unit;

(d) each fan unit chamber/cell having at least one acoustically absorptive insulation surfaces;

(e) said each fan unit chamber/cell being arranged within an air-handling compartment such that the air from all of said fan units is mixed before it enters the structure; wherein; and

(f) each of said plurality of fan units is suspended within a fan unit chamber/cell such that there is an air passageway therebelow.

3. A fan array fan section in air-handling system comprising:

(a) at least three fan units;

(b) each of said at least three fan units positioned within a fan unit chamber/cell which substantially surrounds said fan unit;

(c) each fan unit's chamber/cell having at least one insulating surface;

(d) said at least three fan units arranged in a fan array;

(e) wherein said fan unit chamber/cell is cube-shaped;

(f) said cube having a frame which forms four edges of said cube; and

(g) said insulation surfaces are independent of said frame and from the portion of said cube not formed by said frame.

4. The fan array section in a air-handling system of claim 3 , said insulation surface of said fan unit chamber/cell together forming a co-planar silencer

5. The fan array section in a air-handling system of claim 3 , wherein each said insulation surface is acoustically absorptive material.

6. The fan array section in a air-handling system of claim 3 , wherein sound waves from said fan units passing through said insulation surfaces are at least partially dissipated as they pass therethrough.

7. The fan array fan section in air-handling system of claim 3 , wherein each of said at least three fan units is suspended within a fan unit chamber/cell such that there is an air relief passage therebelow.

8. The fan array fan section in air-handling system of claim 3 , wherein said at least three fan units are a plurality of fan units arranged in a fan array configuration selected from the group consisting of:

(a) a true array configuration;

(b) a spaced pattern array configuration;

(c) a checker board array configuration;

(d) rows slightly offset array configuration;

(e) columns slightly offset array configuration; and

(f) a staggered array configuration.

9. The fan array fan section in an air-handling system of claim 3 , wherein said at least three fan units are plenum fans including at least two vertically arranged fan units.

10. The fan array fan section in an air-handling system of claim 3 , wherein each of said at least three fan units is mounted in a grid system.

11. The fan array fan section in an air-handling system of claim 3 , said fan unit chamber/cells being modular units for in a modular unit system.
