    Patent number: 7658786
    Abstract: The present invention provides a method for improving the air quality in the limited space and the equipment using thereof. The said method is that the air suctioned from the limited space is transferred to the outside of the limited space and acts as an air source for making oxygen. The oxygen is extracted from the said air source and the waste gas generated thereby is directly discharged to the outside of the limited space. The oxygen extracted is transferred into the limited space and offered the said space by means of the oxygen-supply controller. In addition, the atmosphere is supplemented into the limited space when the air inside is suctioned out.
