A fan assembly is disclosed. The fan assembly is comprised of a fan with a motor and a blade as to create an airflow, and an actuator which is adapted to move the fan in vertical and horizontal directions, such that the fan directs airflow below it. The fan further comprises a controller adapted to control the adapter, and a remote control which is adapted to control the controller. The remote control sends signals to direct the controller, and both are adapted such that the movement of the fan can be programmed to a path set by a user and can also be manipulated to a static position set by the user. Preferably, the remote control is a smart device, such as a smart phone.

In certain embodiments, a packaged terminal device for killing pests in an affected area includes a housing configured to be positioned at least partially within an affected area, a fan positioned within the housing, and one or more heating elements positioned within the housing. The fan is operable to draw a flow of air from the affected area into the housing. The one or more heating elements are operable to generate heated air by transferring heat to the flow of air. The packaged terminal device further includes a control unit operable to control the operation of the one or more heating elements in order to cause the packaged terminal device to operate in either a first mode or a second mode. In the first mode, the operation of the one or more heating elements is controlled such that sufficient heated air is generated to heat at least a portion of the affected area to a temperature less than or equal to a first predefined temperature. In the second mode, the operation of the one or more heating elements is controlled such that sufficient heated air is generated to heat at least a portion of the affected area to a temperature greater than or equal to a second predefined temperature, the second predefined temperature being greater than the first predefined temperature.

An air conditioner includes a housing, an outdoor heat exchanger assembly including an outdoor heat exchanger and an outdoor fan, an indoor heat exchanger assembly including an indoor heat exchanger and an indoor fan, an intake conduit defining a make-up air (MUA) air flow path, a MUA fan provided in the MUA air flow path, and a heater bank. A method of operating an air conditioner includes determining that a heating function of the air conditioner is inactive; activating the MUA fan to supply MUA to the indoor heat exchanger while the heating function is inactive; determining a supplemental heating condition after activating the MUA fan; and activating the heater bank to heat the MUA within the MUA air flow path in response to determining the supplemental heating condition.

An indoor unit for an air conditioning device that can increase the strength of a casing of the indoor unit, increase the stability of the indoor unit, and promote cooling of an electric component is disclosed. The indoor unit for the air conditioning device includes a casing formed with an intake air port in a lower portion thereof, and formed with an exhaust air port in an upper portion thereof, a fan arranged inside the casing, and generating air flow from the intake port to the exhaust port, a heat exchanging device arranged below the fan inside the casing to exchange heat with the air taken into the casing from the intake port, and an electric component case provided at a position adjacent to a lateral side of the fan in a circulation space of the air in the casing and configured as a strengthening member of the casing.

An illumination apparatus with air filtration and ultraviolet sterilization functions includes a cover, a carrier board, and a base. The cover includes a first region, a second region, a third region, a light source, and meshes. The light source is disposed at the second region. The meshes are disposed at the first region and the second region respectively.

The openings are formed on the plate for leading air flowing from the meshes. The ultraviolet light is disposed between the openings for sterilizing the flowing air. The negative ionizer is disposed on the plate to generate negative ions in the air. The base is attached to the carrier board and includes a ventilator for providing suction power to lead the flowing air.

An HVACR fan and heater assembly accounts for the cyclonic flow produced by centrifugal blowers by placing a heater vertically and biased towards a side of a fan cabinet in order to increase and balance airflow through the heater, eliminating hot spots and fire risk and improving heater efficiency. A blockoff in the fan cabinet forces airflow within the cabinet to move through the heater. The positioning of the heater may vary depending on the direction of rotation of the centrifugal blower. The fan and heater assembly may further include baffles to direct the airflow from the centrifugal blower.
