摘要： A fan system includes a motor, a rotatable hub, and a plurality of fan blades. Each of the fan blades includes a substantially rigid spine member, a resilient leading edge member, and a resilient trailing edge member. The leading edge member and trailing edge members are removably coupled with the spine member, such that different leading edge members and different trailing edge members may be chosen to customize the leading and trailing edges of the fan blades. Each fan blade may have more than one type of leading edge member or more than one type of trailing edge member. The leading edge member and trailing edge member may each be coupled with the spine member by urging the leading edge member and trailing edge member in a direction that is substantially perpendicular to the longitudinal axis defined by the spine member.

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.

摘要： A system for mounting a fan to a ceiling includes a connector adapted to attach to the ceiling. The connector includes at least one guide. An adaptor is adapted to attach the fan to the connector, and includes at least one rail adapted for being received within the at least one guide. A safety bracket is also provided, which is adapted to attach to the ceiling separate from the connector and connect to a safety cable without using a tool. A motor support is also provided with a cavity adapted to receive the power supply, and at least one retainer serves to retain the power supply within the cavity. A quick-connecting escutcheon is also adapted to rotatably connect to the connector.

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 fan includes a motor adapted to be rotated about an axis and a hub adapted to be rotated by the motor. The hub may include first and second hub parts adapted to mate to form the hub, the first and second hub parts having a gap therebetween. A plurality of fan blades each includes an end portion located in the gap formed between the first and second hub parts, which may be drawn together by a fastener to capture the blades therebetween. One or more of the fan blades may include a receiver, such as an open-ended groove, for receiving a portion of the hub. An adapter may be configured to remain stationary during use while the hub and fan blades rotate, and a portion of the hub is adapted to be selectively deployed to engage the adapter to prevent rotation of the hub. Related methods are also disclosed.

摘要： An apparatus for controlling a device in connection with a sensed temperature in a space includes an actuator for regulating the operation of the device, a temperature sensor for providing the sensed temperature, and a thermal antenna connected to the temperature sensor. The thermal antenna may form part of the exposed face of the apparatus. A housing may include partitions, such as a plurality of circuit boards, for communicating with the actuator to provide control for the device. The partitions or circuit boards are spaced apart to form ventilation channels for ventilating heat from the housing, including byway of an encouraging convective flow.

摘要： A fan for generating germicidal light is disclosed, which may be adapted to mount to a ceiling. The fan includes a hub connected to a plurality of fan blades. A motor is adapted to rotate the hub. A support is adapted to support the hub and motor from the ceiling. A lighting module may include a tray adapted to receive the support, the tray including one or more lights for providing ultraviolet germicidal light. The light may be provided by LEDs on a circuit board adapted for positioning around the support without dismounting the support from the ceiling, such as one comprised of wedge-shaped segments. The modular circuit board may form part of an uplight module supported by a housing for the motor.
