Abstract: A fan assembly (10) includes a shrouded fan rotor (18) having a plurality of fan blades (22) extending from a rotor hub (24) and rotatable about a central axis (20) of the fan assembly, and a fan shroud (26) extending circumferentially around the fan rotor (18) and secured to an outer tip diameter of the plurality of fan blades (22). A fan casing (16) encloses the shrouded fan rotor (18). The fan casing (16) defines a fan inlet (30) of the fan assembly and includes an inlet extension (54) at an outer diameter of the fan casing, extending axially upstream of a conventional bell mouth inlet (58), relative to a direction of airflow through the shrouded fan rotor (18).

Abstract: A condensate drain pan including a drain pan surface, a front wall, including a front wall longitudinal axis, a rear wall, and opposing side walls. The front wall, the rear wall, and the opposing side walls extend from the drain pan surface. The front wall includes a first aperture and a second aperture. The first aperture and the second aperture include an aperture axis.

Abstract: A fan assembly (10) includes a shrouded fan rotor (24) including a plurality of fan blades (28) extending from a rotor hub (30) and rotatable about a central axis (26) of the fan assembly and a fan shroud (32) extending circumferentially around the fan rotor (24) and secured to the plurality of fan blades (28). The shroud (32) has a first axially extending annular portion (38) secured to the plurality of fan blades (28), a second axially extending annular portion (40) radially outwardly spaced from the first axially extending annular portion (38), and a third portion (44) connecting the first (38) and second (40) axially extending annular portions. A casing (22) is positioned circumferentially around the fan shroud (32) defining a radial clearance between the casing and the fan shroud. The casing (22) includes a plurality of casing elements (48) extending from a radially inboard surface (46) of the casing toward the shroud (32) and defining a radial element gap and an axial element gap.

Abstract: An integrated fan heat exchanger stator assembly is provided including a hub and a casing. A plurality of elements is arranged between the hub and the casing. The plurality of elements is separated from one another by a plurality of external flow passages. At least one internal flow passage is configured to convey a first heat transfer fluid through one or more of the plurality of elements. The first heat transfer fluid is arranged in thermal communication with a second heat transfer fluid configured to flow through at least one of the external flow passages.

Abstract: A fan assembly includes a shrouded fan rotor having fan blades extending from a hub and rotatable about a central axis. A fan shroud extends circumferentially around the fan rotor and secured to the fan blades. The shroud includes a first axially extending annular portion secured to the fan blades, a second axially extending annular portion radially outwardly spaced from the first axially extending annular portion, and a third portion connecting the first and second axially extending annular portions. A casing is located circumferentially around the fan shroud defining a radial clearance between the casing and the fan shroud, and includes casing wedges extending from a radially inboard surface of the casing toward the shroud and defining a radial wedge gap between a first wedge surface and the shroud and an axial wedge gap between a second wedge surface and an upstream end of the fan shroud.

Abstract: An air handling unit for use with an air conditioning system is provided including a housing duct through which air is circulated. A vane-axial flow fan circulates air through the housing duct. The fan includes an impeller having a plurality of fan blades extending therefrom and an axis of rotation arranged substantially in-line with a flow path of the air. A heat exchanger assembly is arranged within the housing duct in a heat transfer relationship with the air circulating through the housing duct.

Abstract: A condensate drain pan including a drain pan panel, including a panel interior side and a panel exterior side, a channel member formed on the panel exterior side, a front wall, a rear wall, and opposing side walls. The front wall, rear wall and opposing side walls extend from the drain pan panel to form a receptacle, and the front wall includes a first aperture and a second aperture in the front wall.

Abstract: A condensate drain pan including a front wall, including a front wall longitudinal axis, a rear wall, and opposing side walls extending from a drain pan surface. The front wall includes a first aperture and a second aperture, including an aperture axis, wherein the aperture axis forms an angle less than 90 degrees with the front wall longitudinal axis.

Abstract: A fan assembly includes a shrouded fan rotor having fan blades extending from a hub and rotatable about a central axis. A fan shroud extends circumferentially around the fan rotor and secured to the fan blades.
