DEVICE FOR RAPIDLY SUPPLYING OXYGEN FOR AIR CONDITIONER SUPPLYING OXYGEN-ENRICHED AIR

摘要

PURPOSE: A device for rapidly supplying oxygen for air conditioner supplying oxygen-enriched air is provided to minimize time needed for concentration of indoor oxygen to return to normal value. CONSTITUTION: A device includes an air compressor for oxygen storage(2) compressing oxygen-enriched air taken in from an oxygen-enriched air separator(320); a check valve(1) opening and closing an oxygen-enriched air passage extending from the oxygen-enriched air separator to the air compressor for oxygen storage and preventing backflow of oxygen-enriched air to the oxygen-enriched air separator; an oxygen storage tank(3) connected to an outlet of the air compressor for oxygen storage to store compressed oxygen; an opening valve(5) opening and closing a passage of oxygen-enriched air discharged from the oxygen storage tank into a room according to concentration of oxygen in the room; and a pressure sensor(4) installed on the outlet of the oxygen storage tank and detecting inside pressure of the oxygen storage tank to control opening and closing of the check valve and the opening valve.
