<p>PROBLEM TO BE SOLVED: To provide an economical storage chamber of a lightweight, compact structure capable of easily adjusting the intra-chamber condition into a specified low-humidity atmosphere or a low-humidity and low oxygen gas concentration atmosphere and of keeping the adjusted condition stably. SOLUTION: A gas separator device is configured so that the dry air or a dry enriched nitrogen gas obtained by removing the water vapor and/or oxygen gas selectively from the air outside the storage chamber 10 is fed into the chamber, wherein a sensor 12 and the gas separator device are coupled together through a control device 13, and the operation of a gas separating membrane device is controlled using the measurements of the humidity or oxygen concentration inside the chamber obtained by the sensor so that the inside of the chamber is kept at the preset humidity and/or oxygen concentration.</p> |
