Abstract
A fan array fan section in air-handling system includes a plurality of fan units arranged in a fan array. Each fan unit is positioned within a fan unit chamber/cell. Each fan unit chamber/cell has at least one acoustically absorptive insulation surface. The insulation surfaces of the fan unit chamber/cells together form a coplanar silencer. Sound waves from the fan units passing through the insulation surface at least partially dissipate as they pass therethrough. In one preferred embodiments the fan unit chamber/cell is a cell having a frame that supports the insulation surface.
Claims11
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.
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.
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.
