b. Air handling units serving records storage and processing areasmust provide sufficient air exchanges to maintain requirements fortemperature, relative humidity, and pollutant control. The numberof air exchanges are determined by the planned size of the room,volume of records, volatile organic compounds coming off therecords, occupancy, etc.
空气调节系统必须为档案库房和档案工作间提供足够空气交换量，保证档案库房和档案工作间的温度、相对湿度和有害气体控制的要求。空气交换量要根据房间的大小、存档数量，档案挥发出的有机化合物和占用率来决定。
