摘要： A temperature door for an air handling system of a heating, ventilating, and air conditioning system includes a first surface defining a sealing perimeter and a pivoting structure coupled to the first surface and defining an axis. The first surface is configured to pivot about the axis in the housing of the air handling system. A sealing lip is disposed about the sealing perimeter of the first surface and is adapted to engage a corresponding sealing surface of the housing of the air handling system. A pivoting of the first surface about the axis from a sealed position causes a progressive disengagement of the sealing lip from the sealing surface beginning in a location proximate the axis while at least a portion of the sealing lip remains engaged with the sealing surface at a location spaced from the axis.

摘要： A blower wheel for use in a blower assembly is disclosed, wherein the blower wheel includes a hub, a concentrically arranged outer ring, and an array of spaced apart blades arranged on an outer periphery of the hub and extending between the hub and the outer ring. The hub includes a wave configuration formed therein. The wave configuration includes an annular array of crests and an annular of troughs alternately formed in at least one of an outer surface and an inner surface of the hub. The hub may also include an annular array of support members formed on the inner surface thereof.

摘要： A blower assembly includes a housing having a blower wheel disposed therein and a pre-swirler disposed in a fluid inlet of the housing. The pre-swirler includes an array of spaced apart vanes extending radially outwardly from a central hub. The vanes extend from the hub to an outer ring that is attached to the housing of the blower assembly. The vanes are configured to cooperate with the blower wheel to minimize a noise, a vibration, and a harshness (NVH) of the blower assembly, while maximizing an efficiency thereof.

摘要： A blower wheel for use in a blower assembly includes a hub, a concentrically arranged outer ring, an array of spaced apart blades extending between the hub and the outer ring. The hub includes an outer first surface and an inner second surface. An interface between an outer edge of a first end of each of the blades and an outer peripheral edge of the outer first surface of the hub is minimized, increasing an effective blade exit height of the blower wheel. As such, an effective open area for airflow between the blades of the blower wheel is increased over that of the prior art blower wheels. Further, a substantially planar lower face of the hub provides additional structural integrity to the hub, and thereby the blades.
