Abstract

An air moving device has a housing with a primary flow path and a secondary flow path that extends from a secondary inlet of the housing and empties into an inner outlet adjacent the primary flow path. An impeller assembly rotates a blade to cause air to enter the housing and flow along the primary flow path. The flow of air through the primary flow path creates a low pressure region at the inner outlet of the secondary flow path, causing air to flow through the secondary flow path and mix with the air in the primary flow path. The mixture of air flows through a downstream portion of the primary flow path having an expanded width compared to an upstream portion of the primary flow path and exits the housing. Stator vanes may extend longitudinally within the housing to cause columnar air flow. The device may be used for destratification of thermal gradients of air within an enclosure, such as a home or warehouse.

• F04D 25/08 - Units comprising pumps and their driving means the working fluid being air, e.g. for ventilation
• F04D 29/54 - Fluid-guiding means, e.g. diffusers

Abstract

An air moving device includes a housing member, an impeller assembly, and a nozzle assembly. The nozzle assembly can include one or more angled vanes set an angle with respect to a central axis of the air moving device. The air moving device can output a column of moving air having an oblong and/or rectangular cross-section. A dispersion pattern of the column of moving air upon the floor of an enclosure in which the air moving device is installed can have an oblong and/or rectangular shape. The dimensions of the dispersion pattern may be varied by moving the air moving device toward or away from the floor, and/or by changing the angles of the stator vanes within the nozzle assembly.

Abstract

An air moving system includes an air moving device including a housing member, a rotary fan assembly, and an opening for connection with an airflow duct, the housing including a plurality of air intake vents. A first volume of air can enter the housing through the opening and a second volume of air can enter the housing through the plurality of intake vents. The rotary fan assembly directs the first and second volumes of air.

Abstract

An air moving device includes a housing member, a rotary fan assembly, and a nozzle. The air moving device further includes a light source member mounted within the nozzle. The light source member can be placed within a flow of air moving out the end of the nozzle in a generally columnar pattern. The flow of air can be used to cool the light source member. A portion of the nozzle can be transparent, allowing the light, from the light source member to emanate radially, as well as longitudinally.

Abstract

An air moving system includes an air moving device including a housing member, a rotary fan assembly, and a nozzle, the housing including a plurality of air intake vents. The nozzle is configured to move relative to a longitudinal axis of the air moving device. The air moving system includes a ceiling grid structure. The air moving device is configured to rest within a grid within the ceiling grid structure or within an opening in the ceiling.

Abstract

A columnar air moving device can comprise sepa-rately formed modular stator vanes in a stator vane assembly. The stator vanes can be arranged in a radial pattern, and can direct air in an axial direction. The modular stator vanes, as well as other com-ponents of the stator vane assembly, can be replaced, adjusted, and/ or removed from the columnar air moving device.

Abstract

Air moving device includes a housing, an impeller in the housing for generating a downward air flow, and vanes in the housing in close proximity to and a selected distance below the impeller to straighten the air flow. The device produces an air flow that substantially remains in a column over a substantial distance. The method includes producing an air flow that substantially remains in a column over a substantial distance and directing the air flow from the ceiling towards the floor to provide temperature destratification of the air in an enclosed space. The method also includes directing warm air from the ceiling to the floor and storing heat in the floor, apparatus on the floor and storing heat in the floor. The stored heat is released when the ceiling is cooler than the floor.
