PURPOSE: An oxygen supplying apparatus is provided to achieve improved cooling efficiency by permitting the air being supplied to the oxygen/nitrogen separator to have a low temperature. CONSTITUTION: An oxygen supplying apparatus comprises a filter for filtering contaminants from the air flowing into an outdoor unit(30); an intake air muffler(36) connected to the filter, and which reduces noises of the filtered air; an air compressor(40) for compressing the air passed through the intake air muffler; an oxygen/nitrogen separator(44) for separating the air discharged from the air compressor into an oxygen and nitrogen; a solenoid valve interposed between the air compressor and the oxygen/nitrogen separator; and a heat radiation pipe(50) formed by winding pipes for guiding the air passed through the air compressor to the oxygen/nitrogen separator, and interposed between the air compressor and the oxygen/nitrogen separator.
