<p>The present invention relates, in general, to an air supply device, which supplies fresh at¬ mospheric 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.</p> |
