How to do a good job in temperature and humidity control in archives warehouses

To do a good job in temperature and humidity control in archives warehouses, the following aspects need to be done:

1. Establish the understanding of "prevention first, combined with prevention and control", and correct the attitude of scientific management

"Prevention" is the foundation of archives protection. Effective prevention can greatly reduce the burden and cost of "curation" and avoid unnecessary losses of archives. From now on, the scientific management of temperature and humidity in archives warehouses must be included in the important agenda, and corresponding rules and regulations must be established and improved.

2. Establish a team of archives personnel with high professional quality and strong business capabilities

Scientific management of temperature and humidity in archives warehouses is a highly professional task. It not only requires Managers have a strong sense of responsibility and need to have certain scientific and cultural levels, professional knowledge and business skills. The recording, sorting and analysis of temperature and humidity conditions, the selection of temperature and humidity control and adjustment methods, and the use and maintenance of some mechanical equipment and instruments are difficult to do without a certain level of professional skills and a strict and meticulous work style. Therefore, warehouse managers must work hard to learn professional and cultural knowledge, master professional skills, and improve the level of scientific management of warehouse temperature and humidity.

3. Carefully record the temperature and humidity test of the warehouse

Complete and accurate original data are the basis and prerequisite for scientific analysis and effective control, and must be recorded carefully.

1. Pay attention to the integrity of data records. Because the warehouses are located on different floors and orientations, and the temperature and humidity changes are also different, it is necessary to avoid generalizations.

2. Pay attention to the accuracy of data recording. Only with accurate data as a basis can we make correct analysis and decisions.

3. Pay attention to the regularity of data test records. Whether inside or outside the warehouse, it is necessary to select the observation time, frequency and location that best represent and reflect the climate temperature and humidity changes in the warehouse and the surrounding environment, and systematically accumulate original data to facilitate the collation and analysis of statistical data and enhance comparability. sex.

4. Strengthen temperature and humidity analysis and explore changing patterns

Without scientific analysis, data test records will lose their meaning. Only by carefully systematically sorting and analyzing the raw data accumulated in the warehouse over a long period of time can we discover and explore their periodic and non-periodic patterns, thereby making correct judgments and selecting effective opportunities for temperature and humidity control.

5. Take effective temperature and humidity control measures based on objective reality

There are many ways to control and adjust the temperature and humidity of archives warehouses. Practice has proved that the combination of airtightness, ventilation and dehumidification This method is a good way to control temperature and humidity.

1. Sealed. The function of sealing is to prevent or weaken the influence of inappropriate temperature and humidity outside the warehouse on the inside of the warehouse, so as to keep the more suitable temperature and humidity inside the warehouse relatively stable. The key to sealing the warehouse is doors and windows. The specific method is generally to inlay the edges of all doors and windows with woolen strips or flannel through adhesive (such as latex or polyurethane, etc.). Iron doors and steel windows can be embedded with rubber strips. If there are too many and too large windows, only some of them can be left for ventilation, and the other windows can be completely sealed and no longer open.

In order to reduce the influence of temperature and humidity outside the warehouse, the warehouse door leading to the outside of the warehouse should be equipped with a transition room (or moisture-proof room). The width of the transition room is slightly larger than that of the warehouse door, and the depth is about 2m~3m. When entering the warehouse, first open the door of the transition room, close the door of the transition room after entering the transition room, and then open the door of the warehouse to enter the warehouse. If a moisture-proof curtain is installed on the door, the effect will be better.

Sealing only plays a role in controlling the temperature and humidity of the warehouse, and sealing is always relative. Sealing alone cannot control the temperature and humidity of the warehouse within a certain range, so sealing must be combined with regulating the temperature. humidity measures.

2. Ventilation. Ventilation is a method of systematically exchanging air inside and outside the warehouse according to the rules of air flow, so as to regulate the temperature and humidity of the air in the warehouse. Ventilation is not simply about opening doors and windows to allow free exchange of air inside and outside the warehouse, but to grasp the natural flow of air inside and outside the warehouse, compare the actual conditions and changing trends of temperature and humidity inside and outside the warehouse, and carry out it in a planned manner with reference to wind power and direction.

To adjust the temperature of the warehouse, that is, to cool down or increase the temperature, the timing is relatively simple. As long as the temperature outside the warehouse is lower than or higher than inside the warehouse, ventilation can be carried out. However, changes in temperature within the warehouse will inevitably cause changes in humidity, so when ventilating and adjusting the temperature of the warehouse, the impact on humidity must also be considered. If the purpose of ventilation is to reduce the humidity of the warehouse, it must be carried out according to certain principles and cannot just look at the relative humidity inside and outside the warehouse. For example, if the relative humidity outside the warehouse is lower than inside the warehouse, but the temperature is higher than inside the warehouse, the actual amount of water vapor in the air may be higher than inside the warehouse. After ventilation, the humidity inside the warehouse may increase.

3. Humidification. High humidity in the warehouse is mainly caused by various factors such as air moisture, groundwater or rain leakage. Humidification can be done from two aspects: on the one hand, isolating and reducing the sources of humidity, and on the other hand, eliminating the existing humidity in the warehouse. At present, commonly used methods to reduce humidity include mechanical ventilation, dehumidifiers, and drugs to absorb moisture and remove moisture.

The management of warehouse temperature and humidity is a scientific and practical job. It not only requires archivists to have a high degree of enthusiasm and responsibility, but also requires a comprehensive mastery and use of scientific methods and measures. , in order to achieve scientific management of warehouse temperature and humidity and extend the life of files to the maximum extent, so as to better develop and utilize and serve the society.
