内容記述 | The long-term measurement of air quality temperature and humidity and the prediction of air concentrations by numerical analysis were carried out to construct a favorable conservation environment for cultural properties in a highly airtight prefabricated storage where the air concentration of acetaldehyde exceeds the health guidelines (48 μg/m3). Monthly measurements of air quality showed high correlation between the acetaldehyde concentration and temperature. The apparent volumetric emission rate considering temprature dependence was identified from the measured values of acetaldehyde concentrations, and the prediction of annual change of acetaldehyde concentrations was conducted to estimate the effects of ventilation. The calculated results show that the acetaldehyde concentrations exceeded the guideline values from May to mid-November only with passive ventilation, indicating that active ventilation is necessary during this period. The numerical analysis showed that the acetaldehyde concentration recovered to the same values as without ventilation in less than half a day after the total heat exchanger was stopped due to the fast emission rate in summer. In summary, it was shown that characterizing problematic chemicals and understanding their emission behavior can be used to propose appropriate ventilation methods. | |||||
