  • Patent number: 11852360
    Abstract: 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, 143 installed 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. The air management allows customization of air flow. The housing 10 of the furniture-type air management device may be installed on the floor of the livable space and may have a hexahedron shape that extends from side to side. 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.
