Title:
閉鎖された空間の気密性の度合を測定する方法
Document Type and Number:
Japanese Patent JP5299280
Kind Code:
B2
Abstract:
The method involves defining a concentration gradient between internal air atmosphere in an enclosed space and ambient air atmosphere by setting a physical concentration of a constituent component i.e. oxygen, of the enclosed-space atmosphere. A concentration change rate is determined by measuring the time-related change of the physical concentration of one of the constituent components in the enclosed-space air atmosphere. Air-tightness value of the enclosed space is calculated by taking the previously determined concentration change rate into account.
