During regulation and control, when particularly carrying out dehumidification operation by the means of refrigeration, circulation to microenvironment, the temperature of air can be influenceed, so
Must take into consideration influence of the process to microenvironment temperature.
Biological corrosion constitutes main harm, danger similarly for cultural relic conservation, especially because those are by protein, dye
The historical relic that the organic matters such as material, fiber are constituted, its own is the nutriment that microorganism depends on for existence.It is relative in air/definitely wet
Spend most important for carrying the survival volume of microorganism in air.Its humidity for most adapting to of different microorganisms is different, total
For, humidity is more high to be adapted to microorganism growth.
On the other hand, the pollutant such as particulate pollutant in museum's collection microenvironment, microorgranic contaminant, and gaseous state
Destruction of the pollutant to historical relic is also fairly obvious, and these pollutants wide material sources, such as showcase (storage cabinet) and its
Outside museum environment carries out air exchange, gas that the material of showcase (storage cabinet etc.) is discharged etc..These pollutants all can
Influence the preservation of historical relic.
