Study of Ventilation Rate Measurements for Showcases and Facilities in Museums

Masahide INUZUKA and Takeshi ISHIZAKI

The most suitable temperature and relative humidity for the conservation of cultural properties are said to be about 20Ɏ and 60%RH, respectively, by ICCROM, for example. In addition, care has to be taken so that cultural properties would not suffer from rapid changes in temperature and relative humidity because they would destroy cultural properties.

If a showcase is significantly air-tight, variation of relative humidity inside the showcase will be decreased by using a relative humidity buffer. However, if the air-tightness is perfect, VOC emitted from the inner wall would not be discharged, perhaps causing chemical damage to objects. The purpose of this study is to obtain quantitatively the best value of ventilation rate for showcases by considering the relative humidity and VOC emission inside showcases.

For this purpose, first, it is important to understand the measurement of ventilation rate. It is also better for curators if the method of measurement is simple and does not cost much. In this report, two methods are selected and evaluated: (i) concentration decay method using CO₂ as a tracer gas and (ii) monitoring concentration of O₂ after introducing N₂ into a showcase. The accuracy of these measurements is evaluated and the results from both methods are compared.

The impact of a rapid change in temperature on the ventilation measurements is also discussed in this article.
