PURPOSE: A diffuser is provided to keep the indoor environment optimum by making the air flowing out to indoor flow horizontally when cooling by being installed on the lowest part of a duct and by making the air flow vertically when heating in an air conditioning system. CONSTITUTION: A connecting pin(6) of an airflow guide part(4) is installed to be hung on a connecting hook on the bottom when cooling. Herein, the terminals of wings(5) are placed in the same straight line or at the lower part with the terminal of the curved part of an outer body(2). Accordingly, the air drawn out via a duct is drawn out according to the angular degrees and the shape of the wings without regard to the shape of the outer body, so flows horizontally. When heating, the connecting pin is installed to be hung on the upper hook. Herein, the terminals of the winds are placed the inner part than the terminal part of the curved part of the outer body. Accordingly, the air drawn out via the duct is affected by the shape of the outer body. Thereby, the horizontal flow is formed by the wing of a certain position, but the curved part of the outer body forms a vertical flow.
