Modular fan housing with multiple modular units having sound attenuation for a fan array for an air-handling system
DCFirst Claim
1. A fan system configured for use in an air-handling system to deliver air to a ventilation system for at least a portion of a building, the fan system comprising:
- an air handling compartment that includes chambers arranged adjacent to one another in at least one row or column, the air handling compartment having a discharge plenum configured to deliver air to a ventilation system for at least a portion of the building, the chambers having corresponding front and back ends;
motors and fans positioned in the chambers, the fans located to take in air from the front ends of the corresponding chambers and to discharge the air from the back ends of the corresponding chambers, wherein the motors have a corresponding first speed when driven at a first frequency, the fans being configured to deliver an air flow amount based on a speed of the corresponding motor;
sound attenuation layers that extend along at least a portion of the corresponding chambers such that the sound attenuation layers are positioned between at least some of the fans that are adjacent to one another; and
an array controller for controlling said motors, the array controller configured to operate at least one of the motors at a speed that is less than or equal to a first speed to deliver an associated air flow amount from the corresponding one of the fans.

Abstract
A modular fan housing configured to hold an array of motors and fans is provided. The modular fan housing is configured for use in an air-handling system that delivers air to a ventilation system for at least a portion of a building. The fan housing comprises a plurality of modular units configured to be stacked adjacent to one another in at least one row or column to form an array. The modular units each include an interior surface and have a front end and a back end that define a chamber. The chambers are configured to receive the motors and fans. Sound attenuation layers extend along at least a portion of the interior surface of the corresponding chambers. The sound attenuation layers are positioned between at least some of the adjacent chambers.
