A laminar flow diffuser with integrated lighting has a frame for supporting an air plenum and a lower housing. The air plenum receives conditioned air from a source of conditioned. The lower housing is attached to the bottom of the plenum. An aperture plate damper installed below the top plenum regulates the flow of air from the plenum through the laminar flow diffuser. A clear or translucent engineered, fire rated polymer perforated diffuser face forms the outlet from the lower housing to the room below. LED strips are positioned around the inside periphery of the lower housing. A light guide is installed adjacent the LED lighting strips to spread the light across the area of the perforated diffuser face.

Disclosed herein is an air conditioner. The air conditioner includes a housing having an inlet and an outlet, a blade having a plurality of discharge holes and provided to discharge air through the plurality of discharge holes, a first opening formed between one side of the blade near the inlet and the housing when the blade discharges air through the plurality of discharge holes, and a second opening formed between the housing and the other side opposite to the one side of the blade when the blade discharges air through the plurality of discharge holes.

A ceiling type air cleaner comprises a housing comprising an opening arranged on a lower side of the housing; a filter arranged on a side of the opening; and an edge plate arranged on the lower side of the housing to support the filter and comprising a locking portion configured to lock the filter to the housing and unlock the filter from the housing. The locking portion comprises a space portion forming a space inside the edge plate; a sliding member configured to slide along the space portion; a fitting member configured to allow the sliding member to be fixed to or released from the space portion so as to allow the sliding member to slide; and a link configured to rotate according to the sliding of the sliding member so as to lock the filter to the housing or unlock the filter from the housing.

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.

An easy access air vent is an apparatus that facilitates the maintenance of the air vent as well as other accessories equipped to the air vent. The apparatus includes a vent frame, a vent grate, a scent dispenser, a filter-receiving bracket, a wall frame, a replaceable air filter, and a replaceable scent cartridge. The wall frame secures the apparatus to the desired surface. The vent frame facilitates the maintenance of the replaceable air filter and the replaceable scent cartridge. The vent grate guides the airflow through the vent grate towards a desired direction. The scent dispenser retains the replaceable scent cartridge to enable the dispensing the scent in the airflow. The filter-receiving bracket retains the replaceable air filter in an accessible manner against the vent frame. The replaceable air filter removes pollutants from the airflow. The replaceable scent cartridge contains the scent material that is carried by the airflow.

An air management device may include three independently operated primary impellers 131, 131′, 131″, and drawn-in air is discharged through discharge ports 15′-1, 15′-2, 15′-3 provided in the front plate 15 of the housing 10. Louvers 141, 142, 143installed downstream of the air flow and discharge ports 15′-1, 15′-2, 15′-3 may be independently opened or closed to provide discharge of the air to the surrounding environment. Further, at least one retractable or pop-up fan may be provided. A bottom inlet 11′ may be formed on the bottom plate 11 of the housing 10 facing the floor of the living space above a predetermined distance. The replaceable filter 300 may be installed to filter the air sucked through the bottom inlet 11′, and may be drawn in and out of the housing 10.

A blower assembly for a heating, ventilation, and/or air conditioning (HVAC) system includes a centrifugal fan having a fan wheel. A plurality of blades are coupled to the fan wheel at an inner blade boundary and extend radially to an outer blade boundary. The blower assembly includes a first housing panel and a second housing panel disposed on opposite sides of the centrifugal fan and extending transverse to the centrifugal fan. The blower assembly includes a wall extending between the first housing panel and the second housing panel and a flange extending from the wall at a vertex. The flange extends outwardly from the wall. A first radial distance from the vertex to the outer blade boundary is between 4 percent and 20 percent of a second radial distance from a rotational axis of the centrifugal fan to the outer blade boundary.

An air conditioner and a method for controlling an air conditioner are provided. The air conditioner may include a case that forms a space therein with an open lower side; a panel that is disposed at lower side of the case, and has an inlet and a plurality of outlets disposed around the inlet; a fan that is disposed in the case; a plurality of wind adjuster that is disposed in each of the plurality of outlets, and adjusts a direction of air flowing through each of the plurality of outlets; a camera that obtains an image of an indoor space; and a controller that controls the plurality of wind adjusters based on image information obtained from the camera. The controller may divide the plurality of outlets into a first area outlet and a second area outlet, and adjust each of the plurality of wind adjusters so that airflows of air discharged through the first area outlet and airflows of air discharged through the second area outlet are formed differently.

A passenger cabin air distribution system includes a ventilation system and an ejector-diffuser. The ventilation system is operable to provide a conditioned air. The ejector-diffuser is positioned to receive a flow of the conditioned air from the ventilation system. The ejector-diffuser includes an induction unit and a diffuser section. The induction unit includes a secondary inlet in communication with a cabin air from a passenger cabin and is configured to mix the flow of the conditioned air with an induced flow of the cabin air into a mixed air. The diffuser section includes a discharge to eject the mixed air to the passenger cabin. The diffuser section is shaped to provide for efficient mixing with low backpressure in order to maintain the low motive pressure in the nozzle.
