With the progress of human society and the improvement of social productivity, the era of changing things has gradually passed. People's demand for currency inventory is also increasing, and the number of banks of all types is growing at a rapid rate. At the same time, a very important place has been derived-bank vault. Bank vaults are currently used to store some gold, precious metals, paper money, coins and some bonds.

The effect of temperature on bank vaults

If the temperature is too high, it will cause the volatilization of the solute inside the printing oil on the banknote bond, making the banknote dry and brittle, which will be fragile and not conducive to storage. At the same time, if the temperature is too high, it may cause the combustion of flammable substances. The temperature is too low, will affect the size of the humidity, humidity is the factor that affects the zui.

The effect of humidity on bank vaults

How big the bank vault is built underground, the earth gas will seep into the corner, usually the ambient humidity will be relatively high. But humidity has a big impact on the storage of metal money, paper money and bonds. Humidity is too high, will lead to paper money erosion, damage its internal fiber structure, will also lead to paper money moldy scrap. Metal currency, such as gold in a high humidity environment for a long time, will gradually be oxidized corrosion, reduce the service life, in circulation, due to high humidity produced by bacteria will also endanger human health. There are also some gold and silver ornaments with historical value, which will easily become dull in high humidity and lose their original ornamental value.

Suitable temperature and humidity for bank vaults

The temperature is below 30 ℃, but the temperature should not be too low, it will affect the humidity, and the humidity should be controlled by each other;

The humidity zui is preferably between 20% RH and 50% RH, and the storage of metal products shall not exceed 70% RH;

temperature and humidity control measures:

①    Install automatic temperature and humidity recording alarm, when the temperature and humidity is abnormal, the staff timely ventilation and constant temperature treatment, the reservoir area for day and night monitoring.

②    For direct inspection of currencies, if there is a harsh gas in the vault, it means that the temperature is high; if there is a pungent gas, it means that the humidity is high, and such currencies should be dealt with in a timely manner.

③    Install HVAC or air conditioning equipment, regularly feed natural air, dry air.

④    Use moisture absorption machine or frozen dehumidifier to reduce the humidity in the warehouse.

⑤    Reasonably design the building structure, increase the circulation of natural wind, and avoid cold and hot air convection in winter.

No matter what kind of control measures, it is necessary to measure the temperature and humidity in real time during the control process. Here are two kinds of temperature and humidity sensors.

Low Power Chip Level Temperature and Humidity Sensor-- HTU21D
