Abstract
A fan array fan section in an air-handling system includes a plurality of fan units arranged in a fan array and positioned within an air-handling compartment. One preferred embodiment may include an array controller programed to operate the plurality of fan units at peak efficiency. The plurality of fan units may be arranged in a true array configuration, a spaced pattern array configuration, a checker board array configuration, rows slightly offset array configuration, columns slightly offset array configuration, or a staggered array configuration.

A fan array fan section in an air-handling system to supply air to a building, comprising:
- an air handling compartment having a discharge plenum configured to deliver air to a ventilation system for at least a portion of the building;
- a fan array of at least three fan units positioned in the air handling compartment, the fan units having motors and fans, the motors having a corresponding nameplate rated speed, the fans being configured to deliver an air flow amount based on a speed of the corresponding motor;
- a speed controller to operate at least one of the motors at a first speed that is equal to or below the nameplate rated speed to deliver a first air flow amount from a corresponding one of the fans;
- and
- the speed controller to operate the at least one of the motors at a second speed that is greater than the nameplate rated speed to deliver a second air flow amount from the corresponding one of the fans.
A method of implementing a fan array air handling system to supply air to a building, the air handling system including an air handling compartment having a discharge plenum configured to deliver air to a ventilation system for at least a portion of the building;
- the method comprising:
- obtaining a fan array of at least three fan units positioned in the air handling compartment, the fan units having motors and fans, the motors having a corresponding nameplate rated speed, the fans being configured to deliver an air flow amount based on a speed of the corresponding motor;
- configuring a speed controller to operate at least one of the motors at a first speed that is equal to or below the nameplate rated speed to deliver a first air flow amount from a corresponding one of the fans;
- and
- configuring the speed controller to operate the at least one of the motors at a second speed that is greater than the nameplate rated speed to deliver a second air flow amount from the corresponding one of the fans.
