An air-processing apparatus is provided that may include a case having an outlet formed therein, at least one louver rotatably disposed in the case to adjust a direction of air flowing through the outlet, and an output device including a lamp, a printed circuit board on which the lamp is mounted, and a transparent panel configured to allow light emitted from the lamp to pass therethrough. The at least one louver may include a plurality of vanes spaced apart from each other in a radial direction about a louver rotational shaft. The transparent panel may be disposed in at least one of the plurality of vanes.

A hinge assembly includes a pair of lower mounting brackets, at least two upper hinge leaves, a pair of side brackets coupled to the sidewalls of the ventilation fan lid, each side bracket having at least one third axle hole therethrough, an axle pivotally coupling the upper hinge leaves to the lower mounting brackets. Each lower mounting bracket has a vertically oval-shaped axle hole. Each upper hinge leaf includes a U-shaped mounting member and a hook shaped clamping plate coupled to the U-shaped mounting member through threaded tension bolts. The upper hinge leaf also has a pair of axle holes. The axle extends through the elongated axle holes of the lower mounting bracket vertical flange and through the axle holes of the U-shaped member.

An air conditioner, a control method for an air conditioner, and a computer-readable storage medium are provided. The air conditioner has a body, an air outlet, and an air output assembly for adjusting the air output of the air outlet. The air conditioner further has a detection device and a controller. The detection device acquires a distance value of a target object from the air conditioner. The controller is electrically connected to the air output assembly and the detection device, and controls the air output assembly to switch among different operative configurations based on the distance value.

A louver assembly includes a support, a plurality of blades, and an insert. The support extends along a length and includes a plurality of slots formed therethrough. Additionally, each louver blade of the plurality of louver blades includes a retention aperture formed therethrough, where each louver blade of the plurality of louver blades extends through a respective blade aperture of the plurality of blade apertures. Moreover, the insert extends through the retention aperture of each louver blade of the plurality of louver blades.

A panel assembly includes a panel, a panel frame, and an air guide plate. The panel frame is in annular shape and fitted over the panel. The panel frame includes a plurality of air outlets spaced apart from each other and surrounding the panel, and an air baffle rib provided at an appearance surface of the panel frame and located on a side of the air outlets away from the panel. The air guide plate is movably arranged at the air outlets.

An air conditioner indoor unit includes a body including an air outlet, an outer air deflector provided at the air outlet and configured to open and close the air outlet, and an inner air deflector located at an inner side of the outer air deflector. The inner air deflector includes a plurality of vent holes penetrating the inner air deflector in a thickness direction of the inner air deflector. A total area of the plurality of vent holes is not smaller than 50% of a total area of the inner air deflector.

An apparatus, system and method for controlling airflow is described. The apparatus comprises a wall which delimits a flared bore. The apparatus further comprises at least one air guide member which retractably protrudes into the flared bore from the wall. The flared bore widens to an outlet, thereby to permit a diverging airflow to be expelled therefrom when each of the at least one air guide member is retracted. When the at least one air guide member protrudes into the flared bore, air flowing in the flared bore is guided by a surface, e.g. a concave surface, of the respective air guide member away from the wall and towards the outlet. The retractable air guide member thus enables the direction and/or degree of convergence of the air flowing out of the outlet to be controlled.

A heating, ventilation, and/or air conditioning (HVAC) system includes a damper assembly configured to regulate airflow and having a frame. The HVAC system includes a first damper blade piece having a first airfoil surface and a second damper blade piece having a second airfoil surface. The first damper blade piece and the second damper blade piece are configured to couple with the frame, and are configured to interlock with one another to form a damper blade having an airfoil shape.

This document describes a high efficiency dehumidification system (HEDS) and method of operating the same. The HEDS systems and physical implementations can include a variety of equipment, such as fans, fluid-conveying coils, tubing and pipes, heat transfer coils, vents, louvers, dampers, valves, fluid chillers, fluid heaters, and/or the like. Any of the implementations described herein can also include controls and logic, responsive to one or more sensors or other input devices, for controlling the equipment for each implementation described herein. The HEDS system utilizes heat transfer between the fluid within the fluid-conveying coils and air passing over the coils to convert humid air into dehumidified air.

The present disclosure relates to an indoor unit of an air conditioner, the indoor unit including: a case having an outlet elongated in one direction; a first vane disposed at the outlet; a second vane disposed at the outlet at a position behind the first vane; a drive motor disposed on one side of the outlet and configured to provide a driving force to at least one of the first vane or the second vane; a drive link coupled to a shaft of the drive motor, and having a first end connected to the first vane and a second end connected to the second vane; and a first vane link having a first end connected to the case and a second end connected to an end portion in a longitudinal direction of the first vane, wherein the first vane has a first curvature formed on a surface perpendicular to an air discharge direction and formed in the longitudinal direction, such that the outlet may be tightly closed in response to sagging of a central part of the first vane due to self-weight in a dual vane structure, and in response to torsion that occurs due to a third vane link provided in the dual vane structure.
