摘要： An apparatus is provided for controlling environmental conditions using a fan and a light in connection with a building having a space including a partition, such as a wall. The apparatus may include a control adapted for being mounted to the partition and for coordinating the control of the fan and the light based on a sensed condition, such as temperature or occupancy. Groups of like devices for controlling environmental conditions may be similarly controlled, such as using control. Control may also provide an indication of an operational state of the device(s) controlled by it, or provide for control based on a preference of one or more people upon detecting their presence. Related methods are also described.

摘要： A fan comprises a rotatable hub, a plurality of fan blades coupled with the hub, and a plurality of air fences coupled with the fan blades. Each fan blade has a free end and an opposite end secured to the hub. The air fences are positioned at selected locations along the length of the fan blades, between the ends of the fan blades. Each air fence includes a fin, which may extend upwardly or downwardly from the fan blade. Each air fence may be formed of a resilient material and may be configured to allow the air fence to be snapped onto a fan blade. Each air fence may define an opening through which a fan blade may be inserted. One or more surfaces of the air fence may be contoured to complement a surface contour of an airfoil shaped fan blade.

摘要： A fan includes a temperature sensor, such as a passive infrared sensor, for sensing temperature at a location remote from the fan, such as at a floor, ceiling, or wall, or simply external to the fan housing. This may avoid the influence of heat generated from components of the fan, such as the fan motor or controller for controlling the operation of the fan. A mounting arrangement for forming a connection between two parts, such as components of a fan, is also described.

摘要： A fan, such as a ceiling fan, includes a learning mode of operation. This learning mode may permit a user to input a desired speed for the fan for a given condition, such as ambient temperature, and adjustments for other conditions would be automatically determined based on the user input. A subsequent selection of fan speed at that condition (such as, for example, for a different user) or a different condition setting would also be obtained, either during initialization or later, and then used as an updated measure of the desired fan speed for the condition. Related methods of controlling the operation of a fan are also disclosed.

摘要： A fan blade comprising a root end, a blade region, and a transition region. Wherein each of the root end and blade region comprise a unique profile, and wherein the transition region comprises a profile which transitions the root end profile to the blade region profile. The root end profile comprises a substantially convex top surface, a substantially concave domed sector, and reliefs to allow for the root end to be coupled with a similarly shaped fan hub extrusion. The blade region profile comprises a substantially convex top surface and bottom surface which terminate at a leading edge and trailing edge. The blade region slopes upward along a length of the blade region and terminates at a curved tip.

摘要： A fan includes a hub, several fan blades, and a motor that is operable to drive the hub. A motor controller is in communication with the motor, and is configured to select the rate of rotation at which the motor drives the hub. The fan is installed in a place having a floor and a ceiling. An upper temperature sensor is positioned near the ceiling. A lower temperature sensor is positioned near the floor. The temperature sensors communicate with the motor controller, which includes a processor configured to compare substantially contemporaneous temperature readings from the upper and lower temperature sensors. The motor controller is thus configured to automatically control the fan motor to minimize the differences between substantially contemporaneous temperature readings from the upper and lower temperature sensors. The fan system may thus substantially destratify air in an environment, to provide a substantially uniform temperature distribution within the environment.

摘要： A circulatory device comprising a large diameter fan having reinforced fan blades with a tapered airfoil shape is disclosed. The fan blades may be formed using an extrusion method of fabrication, wherein each fan blade may comprise a reinforced trailing edge with a downwardly extending flange. The benefit of forming each fan blade with a reinforced trailing edge of the present invention results in improved structural characteristics such that the trailing edge of each fan blade may be fabricated longer so as to improve aerodynamic performance. Also, the reinforced trailing edge resists tearing that my occur during extrusion by adding the bent flanged region to at least one distal end of the trailing edge. For example, the bent portion of the trailing edge tends to rigidly orient the extruded material in a stabilized position more readily during formation. Also, the bent portion provides added strength by providing supporting forces in two dimensions that relatively parallel and perpendicular to its length so as to neutralize the adverse effects of pressure forces acting on the trailing edge of the fan blade during extrusion.

摘要： A winglet includes a vertical member and a mounting member. The mounting member is configured to facilitate the mounting of the winglet to the tip of a fan blade. The vertical member is configured to extend perpendicularly relative the tip of a fan blade. A cuff extends from the vertical member to substantially cover at least a portion of the interface between the end of a fan blade and the vertical member. Adding winglets to fan blades may improve the aerodynamics of the fan blades, and thereby increase efficiencies of a fan.

摘要： A system for providing thermal comfort for a person within a space comprising a plurality of interconnected zones, such as a single room in a residence, commercial establishment, or industrial location. At least one fan is positioned in each zone, which may be an overhead fan mounted to a ceiling common to two or more of the zones, and a sensor is provided for sensing a condition in at least one of the zones. A controller is adapted for controlling the fan in the at least one zone independent of another fan based on the sensed condition in the at least one zone including the controlled fan. Related aspects of a thermal comfort control system and methods are also disclosed.
