避难硐室空气净化系统

Air Purification System for Refuge Chamber

为使避难硐室内的被困人员有一个更好的生存环境,延长其生存时间,对避难硐室内的CO2浓度变化规律及空气净化问题进行了深入分析。通过实验舱内2组真人模拟实验,即供干空气条件下,有/无空气净化系统对比实验,对CO2浓度的变化趋势进行数据拟合,得出CO2浓度呈线性增长,而在启用空气净化系统后,CO2浓度得到有效地控制,稳定在0.6%,为避难硐室生存参数的研究提供了依据,证明在避难硐室内建立空气净化系统十分必要。

In order to have a better living environment for the people trapped in refuge chamber and extend their survival time,the variation law of carbon dioxide concentration and air purification problems of refuge chamber were deeply analyzed.Through two groups of real simulations in the experimental chamber,it made comparative experiments with and without air purification system under dry air conditions,and made the data fitting for the trends of carbon dioxide concentration,then obtained that carbon dioxide concentration increased linearly.After the air purification system was enabled,carbon dioxide concentration had been effectively controlled,steady at 0.6%,which provided the basis for survival parameters of refuge chamber,and certified that it was necessary to establish air purification system in refuge chamber.
