A baffle system for a terminal unit of a heating, ventilation, and air conditioning (HVAC) system includes a baffle configured to be disposed within the terminal unit and to receive and extend about an inlet duct of the terminal unit, where the baffle comprises a panel and an insulation layer coupled to the panel.

A door assembly for an air conditioner indoor unit includes a door mounting plate, including a receiving chamber having a fitting opening on one side and a bottom wall on another side, a door arranged adjacent to the bottom wall of the receiving chamber and configured to be movable toward and away from the door mounting plate, and a plurality of driving assemblies arranged in the receiving chamber. An end of each driving assembly passes through the bottom wall of the receiving chamber to be connected to the door. Locations of the ends of the plurality of driving assemblies connected to the door are uniformly distributed on the door. The plurality of driving assemblies are configured to drive the door to move.

An air control system 20 and associated methods including a flexible duct 30 having air exit holes 40, 42 and a flexible liner 50, 60 sheet within the duct 30 and extending longitudinally along the duct, the liner 50 sheet having opposite longitudinal edges 52, 54 connected to the duct 30 along the longitudinal length of the duct 30, the liner 50 sheet being permeable in one aspect and regulating air flow through the exit holes 40, 42 when the sheet is pressed against the portion of the duct having the exit holes, and an air deflector positioned externally the duct to modify airflow exiting the duct. The duct 30 may also have multiple liner sheets 50, 60 arranged end-to-end and/or layered in various duct segments such that the different liners may be independently controlled to regulate the outflow of air from the duct as desired. The duct having a liner which closes or inhibits air flow from the exit holes may also be rotated to accommodate use of a single duct for different seasons and where the internal liner adjusts to assist with the downward control of air flow based on alignment of various perforations with the different exits holes.

An air conditioner, a control method and a computer-readable storage medium are provided. The air conditioner has a body provided with an air outlet. An air output assembly suitable for adjusting an air output angle of the air outlet is arranged at the air outlet. The air conditioner further has a detection device for acquiring position information of a target and a controller electrically connected to the air output assembly and the detection device for controlling the air output assembly according to the position information.

An air conditioner, a control method for the air conditioner, and a computer-readable storage medium are provided. The air conditioner has a body, an air outlet provided on the body, and an air output structure for adjusting an air output angle of the air outlet. The air output structure has multiple operative configurations. The air conditioner also has a detection device for acquiring an ambient temperature and an ambient humidity, and a controller electrically connected to the air output structure and the detection device. The controller controls the air output structure to switch among the operative configurations according to the ambient temperature and the ambient humidity, and further adjusts the air output angle of the air outlet and causes the air output angle and the amount of air output to match with the current ambient temperature and the current ambient humidity.

A pipe bend, in particular for an exhaust air duct of a fume extraction hood, which has a deflection of 60° to 120°, preferably 90°, with an inflow side and an outflow side, wherein the pipe bend has at least one air guide element which is curved in deflection direction and which extends in the interior of the pipe bend, characterized in that the pipe bend has a cross-sectional widening in flow direction behind the inflow side, in particular adjacent thereto, and a cross-sectional tapering in front of the outflow side, in particular adjacent thereto, the course of the bend of the outer wall of the bend deviating from the course of a quarter circle and having a bulge lying outside the vertex of the bend, in particular downstream of the vertex in the direction of flow.

A pipe bend for an exhaust air duct of a fume extraction hood, the pipe bend having at least one multi-part and curved air guide element which extends in the interior of the pipe bend, characterized in that a first and a second part element of the air guide element have a spacing (d) from one another in a radial direction of their curvature.

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.

This application relates to ventilation systems, more particularly to roof ventilation systems that help to protect buildings against fires. The roof vent has an ember impedance structure that impedes the entry of flames and embers or other floating burning materials while still permitting sufficient air flow to adequately ventilate a building. Several configurations of vents employing baffle members and fire-resistant mesh material are described, which can substantially prevent the ingress of floating embers and flames.
