Claim 11:
12. An air management device comprising:
a housing having a primary air flow space and a first secondary space, the primary air flow space extending from a first end to a second end in a longitudinal direction, the first secondary space disposed adjacent to the first end of the primary air flow space such that the primary air flow space is adjacent to the first secondary space in the longitudinal direction, the primary air flow space having at least one air passage to allow air flow through the primary air flow space, the primary air flow space having least two discharge ports installed side by side in the longitudinal direction on a front side of the primary air flow space to discharge air, the air being at least one of filtered air or heat-exchanged air based on the air flow through the primary air flow space;
a plurality of primary impellers provided at positions corresponding to the respective discharge ports and independently operated to pressurize air to create the air flow for delivery of the air in the housing to the at least two discharge ports at the primary air flow space;
a primary impeller guide provided between the at least one air passage and the at least two discharge ports and dividing the air flow to the at least two discharge ports at the primary air flow space; and
at least one discharge unit provided in the first secondary space which is disposed adjacent to the first end of the primary air flow space such that the primary air flow space is adjacent to the first secondary space in the longitudinal direction, and configured to pop-up from or retract from an upper surface of the first secondary space which is parallel to an upper surface of the primary air flow space,
wherein the primary impeller guide includes a prescribed number of primary impeller openings corresponding to a number of the at least two discharge ports,
wherein a branch air flow passage is provided at both ends of the primary impeller guide to divert the air flow flowing through the primary impeller openings;
a connection duct provided between the branch air flow passage and the at least one discharge unit at the first secondary space, and
a damper configured to open or close the connection duct such that the air of the diverted air flow is delivered via the connection duct to the at least one discharge unit at the first secondary space when the damper is open.
