A humidification and air cleaning apparatus is provided that may include a water tank having a discharge port which is open toward an upper side, and a discharge grill disposed at the water tank and covering the discharge port. The discharge grill may have a plurality of vanes disposed at the discharge port and spaced apart from each other, and when viewed from a top, overlap each other to cover the discharge port. An edge of a vane may overlap an edge of an adjacent vane, thereby minimizing scattering of droplets to an indoor space while minimizing resistance of discharged air.

An air conditioner indoor unit includes a chassis, an air duct assembly detachably connected with the chassis, a face frame including a detachment opening configured to allow the air duct assembly to pass through, a first panel configured to open or close the detachment opening, and a second panel configured to cooperate with the first panel to cover a surface of the face frame.

The air conditioning condenser cover comprises a barrier structure, a plurality of weight shafts, a plurality of fastening device sets, and an air conditioner. The air conditioner further comprises an exhaust vent. The plurality of weight shafts and the plurality of fastening device sets attach the barrier structure to the exhaust vent of the air conditioner. The barrier structure forms a protected space that prevents water and debris from entering the exhaust vent of the air conditioner.

An outdoor unit for an air-conditioning apparatus has a roof part installed at a front of a front panel of a casing and above an opening hole and extending in a width direction of the casing, and an outlet grille fixed to the casing and covering the opening hole. The roof part has a main roof portion that extends further forward than the front panel, and a sub-roof portion that extends downward and forward from the main roof portion and has a recession formed between a bottom face of the main roof portion and the sub-roof portion. The outlet grille is located such that an upper end portion of the outlet grille is in contact with the recession. The front panel and the upper end portion of the outlet grille sandwich the roof part.

Provided is an air cleaner, and more specifically, to an air cleaner in which a filter part using a photocatalyst is formed in a module type to facilitate replacement and cleaning and which includes an insert fan which is disposed inward from a suction port of a casing forming an exterior and including the suction port disposed at one side and a discharge port disposed at the other side, and suctions ambient air, a driving motor provided to be axially detachably coupled to the insert fan in a direction from the discharge port, and a suction unit fixing part in which an accommodation space, into which the insert fan and the driving motor are fixedly inserted in the direction from the suction port toward the discharge port and which is finished by inserting a cover member in the direction from the discharge port.

An air filtering system includes a main system and a filtering module. The main system includes a main body having an air inlet, an air flow cover having an air outlet, and a primary filtering core replaceably disposed in the main body, wherein the air flow cover is detachably coupled at the main body to form a basic air filtering mode for filtering air from the air inlet to the air outlet through the primary filtering core. The filtering module is detachably coupled between the main body and the air flow cover to form an advanced air filtering mode, wherein the filtering module includes a secondary filtering core arranged for filtering the air after passing through the primary filtering core and before existing the air outlet.

Technologies are described for a smoke baffle assembly and method of installation. The smoke baffle has a longitudinally extending base with an upper leg, a first leg, and a second leg. A first flange extends inward form the first leg and a second flange extends inward from the second leg. A smoke baffle holder holds an upper portion of a smoke baffle and has a first and second outward extending flange. Each of the outward extending flanges and inward extending flanges is configured and disposed for moving the outward extending flanges into the base and above the inward extending flanges and holding the smoke baffle in the base.

The presently disclosed subject matter is directed to a vent register for use with an HVAC system. The register is defined by a housing comprising top and bottom plates that are permanently joined to create an interior compartment. The interior compartment imparts an insulative quality to the register by providing resistance to an increase or decrease in temperature, such as when cooled air is flowing through the system. The interior compartment can be hollow and filled with air, foam, or any insulative material. In use, the register prevents or reduces the incidence of condensation forming on the face of the register during use.

A vent guard can include a stationary frame and a cage hinged to the stationary frame at a hinged portion. The cage can be configured to engage to the stationary frame at an engagement structure of the cage to support the cage in a closed position to enclose a vent within the cage. The engagement structure can be configured to be slid relative to the stationary frame.

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.
