The archives room is a place to store books, newspapers, documents, tapes, DVDs and other data documents, most of these things are flammable, damp, mildew materials, so if you want the archives to be complete and long-lasting, you need to control the environment of the archives to ensure that the archives are not affected by the environment, especially the air humidity should be controlled in place, otherwise the information inside is easy to be damp and destroyed.
The environment of the archive is very important, especially the temperature and humidity, generally speaking, the temperature needs to be controlled between 20-24, and the daily change of temperature shall not exceed the temperature 2, which can be adjusted by air conditioning, of course, if all are paper archives, then the range of temperature requirements can be a little wider; The requirement for air humidity is between 45-60%RH, and the range of variation cannot exceed 5%, which needs to be controlled by a dehumidifier.
Some people say that today's air conditioners can not only control the temperature, but also have dehumidification functions, so why use a dehumidifier? In fact, the dehumidification function of the air conditioner is an auxiliary function, and if the dehumidification function is specially opened, it will consume the life of the compressor, and there is no humidity control function, which can not control the air humidity in place.
If the archives are dehumidified, it is recommended to use the ZD-8168C series archives dehumidifier, the dehumidifier is composed of a compressor, a condenser, an evaporator, a fan, a drainage system, a casing and a controller, the fan will pump the humid air into the machine during the dehumidification process, and after the evaporator and condenser cooled down to the following temperature by the compressor refrigeration system, the water vapor in the air will precipitate out, condensed into water flowing out through the drainage pipe, and at the same time blow out dry air, and the air humidity can be reduced by continuous circulation.
The microcomputer control system of ZD-8168C series archive dehumidifier can control the air humidity of the archive room between 45-60%RH according to the input air humidity value, so that there is no need to worry about the impact of moisture on files, documents and materials. Compared with air conditioners, dehumidifiers dehumidify quickly, and the system operates according to the feedback information of the humidity probe, which can automatically dehumidify according to the input air humidity value, and the humidity control accuracy can reach 05%。
