Abstract: A centrifugal blower assembly comprises a scroll wall and a pair of opposing sidewalls. The scroll wall is positioned between the pair of opposing sidewalls such that the scroll wall and opposing sidewalls together define a blower chamber and a blower outlet. The blower outlet defines a blower outlet area. An adjustable outlet plate is pivotably coupled to the pair of opposing sidewalls such that the adjustable outlet plate is moveable between a first position to define a first blower outlet area and a second position to define a second blower outlet area.

Abstract: A centrifugal blower for HVACR applications includes a squirrel cage forward-curved blower fan and a scroll housing. The blower fan comprises a plurality of blades that are configured to emit air radially outward and tangentially from between the blades when the blower fan rotates at a first speed. The air so emitted has a deviation angle defined as the difference between the direction of the emitted air and the blade exit angle. The scroll housing has a spline-shaped wall that has an axial cross-section that is configured such that the deviation angle of the air emitted from the blower fan at an axial plane deviates by no more than fifteen percent circumferentially about the blower fan in-between the spline-shaped wall and the blower fan and such that the average tangential velocity of air between the spline-shaped wall and the blower fan deviates by no more than thirty percent.

Abstract: A dual stage blower assembly includes a first fan configured to rotate about the rotational axis and including a first plurality blades. The first plurality of blades include a plurality of backward curved blades. The dual stage blower assembly also includes a second fan circumscribing the first fan and configured to rotate about the rotational axis. The second fan includes a second plurality of blades, wherein the second plurality of blades include one of a plurality of forward curved blades, a plurality of a radial blades, or a plurality of backward curved blades. At least one motor is coupled to the first fan and the second fan and configured to rotate the first fan and the second fan about the rotational axis.

Abstract: A blower assembly includes a housing including an inner shell and an outer shell that define a flow passage therebetween. The inner shell also at least partially defines a cavity. The blower assembly also includes a fan coupled within the housing such that the fan also at least partially defines the cavity. The blower assembly further includes a motor configured to rotate about an axis. The motor is coupled to the inner shell and is positioned within the cavity radially inward of the flow passage.

Abstract: A blower assembly includes a fan assembly configured to rotate about an axis and having a fan inlet ring that at least partially defines a fan inlet and a fan outlet. The blower assembly also includes a frame assembly coupled to the fan assembly and a recirculation damper coupled to the frame assembly. The recirculation damper and the fan inlet ring define an axial gap therebetween to reduce recirculation of an airflow discharged from the fan outlet.

Abstract: A centrifugal blower assembly includes a scroll wall, a pair of opposing sidewalls, and an adjustable cutoff plate. The scroll wall is positioned between the pair of opposing sidewalls such that the scroll wall and opposing sidewalls together define a blower chamber and a blower outlet. The scroll wall extends circumferentially between a cutoff point to an end point and defines a cutout extending circumferentially from the cutoff point. The scroll wall, the pair of opposing sidewalls, and the cutoff point define a blower outlet. The blower outlet defines a blower outlet area. The adjustable cutoff plate is adjustably positioned within the cutout to define a notch defining a notch area. The notch area and the blower outlet area define a total blower outlet area.

Abstract: A forward curved blower wheel has fan blades having relatively small leading edge blades angles and a relatively lengthy mean camber lines. The blower wheel also comprises leading edge notches adjacent its blower wheel inlet. The leading edge notches eliminate buffeting that would occur with such blades if such notches were not present.
