The present invention relates, in general, to an air supply device, which supplies fresh atmospheric air to an air conditioning system, such as an air purifier, an air conditioner, a heater and/or a cooler that is installed in a ceiling of a building. More particularly, the present invention relates to an air supply device, which includes an air supply pipe having a double pipe structure and constituting a passage for guiding atmospheric air to the air conditioning system. Described in detail, the present invention provides an air supply device, which includes an air inlet panel ( 3 ) mounted on an outer wall ( 1 ) of a building, and an air supply pipe ( 5 ) connected at a first end thereof to the air inlet panel ( 3 ) and connected at a second end thereof to an air conditioning system ( 4 ), such as an air purifier, an air conditioner, a heater and/or a cooler that is installed in a ceiling ( 2 ) of the building, thus supplying fresh atmospheric air to a room. A flexible pipe ( 6 ) is installed in the air supply pipe ( 5 ) such that a first end of the flexible pipe ( 6 ) is bent outwards from the air supply pipe ( 5 ) and is fixed using a fastening member ( 7 ), and a second end of the flexible pipe is connected to the air conditioning system ( 4 ). Thus, when the interior of the flexible pipe becomes contaminated with foreign substances, the flexible pipe can be easily replaced with a new one.
