Modular fan housing with multiple modular units having sound attenuation for a fan array for an air-handling system
First Claim
1. A fan system configured for use in an air-handling system, the fan system comprising:
- an air handling compartment comprising a plurality of 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, each of the chambers comprising a front end and a back end, the chambers opening at the back ends into the discharge plenum where the air mixes to provide substantially uniform airflow for the air-handling system;
a fan unit arranged in each of the chambers, each fan unit configured to take in air from the front end of a corresponding chamber and to discharge the air from the back end of the corresponding chamber; and
at least one sound attenuation layer arranged on a portion of at least one of the chambers, the at least one sound attenuation layer positioned between two adjacent fan units.

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.

22. A modular fan system comprising:
-
a plurality of modular units arranged in stacked relationship to one another in at least one row or column, each of the plurality of modular units including a chamber with a front end and a back end; a motor and a fan positioned in each of the chambers of each of the modular units, each fan configured to take in air from the front end of the corresponding chamber and to discharge air from the back end of the corresponding chamber; a sound attenuation layer arranged along a portion of at least one of the chambers, the sound attenuation layer being positioned between two adjacent fans; a discharge plenum connected to the back ends of the chambers, the air discharged from the back ends of the chambers and mixing in the discharge plenum; and an array controller configured to operate at least one of the motors at a speed that is greater than a first speed to deliver an associated air flow amount from the corresponding one of the fans, wherein the first speed is associated with a first frequency that constitutes 60 Hertz. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
