档案库房温湿度与档案寿命密切相关,如何控制库房温湿度,使之符合保护档案的要求,是我馆档案保护技术工作者多年研究的主要课题。一、影响我馆库房温湿度的因素1.气候影响。我馆地处寒温带的松嫩平原,环抱在大小兴安岭、长白山脉之中,受高纬度和季风的影响,形成了冬季漫长寒冷,春季多风干燥,夏季短暂炎热潮湿的气候特点。据我馆记录统计,冰冻期达半年左右,春季3、4、5月份室外平均湿度在40～42%左右;夏季7、8月份室外温度在22℃以上,湿度在65～90%左右。因此,库房在春季加湿、夏季去湿是我馆档案保护技术的一项重要工作。2.库房建筑条件。我馆是1964年建成的老馆,虽经几次改造,但与档案馆建筑规范要求仍有很大差距,特别是没有环廊,没有中央式空调,抗御室外气候影响能力较差,形成了库内温度、湿度随室外变化而变化的不利局面。
Archives room temperature and humidity are closely related to the life of the archives. How to control the temperature and humidity in the warehouse so as to meet the requirement of protecting the archives is the main task for many years’ study on archival protection workers. First, the impact of our library temperature and humidity factors 1. Climate impact. Our museum is located in the frigid temperate Songnen Plain, surrounded by the Great Xinguang Mountains and the Changbai Mountains. Influenced by the high latitude and the monsoon, our museum has the characteristics of a long winter, a windy and dry spring and a brief hot and humid summer climate. According to the statistics of our museum, the freezing period reaches about six months. In spring, the outdoor average humidity in March, April and May is about 40-42%. In summer, the outdoor temperature is above 22 ℃ in July and August, and the humidity is about 65-90%. Therefore, the warehouse humidification in the spring, the summer wet is my library file protection technology is an important task. 2. Treasury building conditions. Our museum was built in 1964 as an old pavilion. Although it has been renovated several times, it still lags far behind the requirements of the archives’ building code. In particular, there is no ring gallery and there is no central air-conditioner to resist the impact of outdoor climate. Library temperature, humidity changes with the outdoor changes in the adverse situation.
