Controlling air humidity in the museum is a key factor in preserving great artworks and historical works.
Museums and archives display a large number of cultural relics and history books for future generations, which has strict control standards on indoor air humidity.
Large changes in temperature and ambient humidity can cause ancient books to freeze or crack. Besides, breeding microorganisms can become active through moisture and heat to damage books. Therefore, the indoor temperature and humidity of museums and archives should be kept constant and consistent. In addition, dehumidification can also be used to preserve microfilm to protect the fragile membrane.

Displacement ventilation is very suitable way for large spaces to control the indoor humidity. But due to the special return air way of the concert hall, different requirements are put forward for the dehumidifier.
The concert hall belongs to the inner area of the building. The unique double-layer envelope structure is sound insulation and heat preservation. Water vapor content in the air is high. It is easy to produce a large number of bacteria, mold and viruses, which is easy to damage indoor air quality and decorations. So the dehumidifier process is the main problem of the concert hall throughout the year.

Moisture can easily make the floor of the house damp, causing the elderly and children to fall down easily. Wall get moist will be prone to mold and cause the wall peeling. Damp furniture and books will easily become deformed. Wet air tends to keep clothes dry in rainy days. Wet quilt is easy to nourish bacteria. For the family, the humid environment not only affects the household things, but also harms the family health. Especially in the extraordinary period when there are many rainy and rainy days, the trouble caused by humidity is even more worrying.

The effect of humidity on furniture. 
When the relative humidity of the environment is lower than 60%, the items are not easy to get wet. Excessive humidity will cause small water droplets on the floor surface, moldy shedding on the wall surface, home appliances are not sensitive to damp control, wall surface paint discoloration, clothes don't get dry easily. What’s more, severe moisture will breed mildew spots or local volume expansion, which will eventually cause the furniture to deform and crack.

Dehumidification function to dry clothes and purify air.
When the relative humidity is lower than 60%, it is the most comfortable environment for the human body. In the case of continuous rainy days, it is impossible to dry clothes. You can use the dehumidifier in the room at this time. It can help you dry clothes without odor, its dehumidification and heating function can solve the problem of clothes drying on rainy days rapidly. Negative ions have the functions of disinfection and purification, inhibit the proliferation of bacteria, and can help to purify indoor air, give people fresh air as nature.

 Bridge dehumidification
 Excellent anti-corrosion protection
 Longer durability
 Save resources.

Corrosion damage may cause high cost of bridge construction worldwide. Corrosion of low-carbon steel components and high-strength supporting steel wires can damage the integrity of the structure quickly, leading to safety issues and expensive traffic restrictions, finally the bridge will be closed.
 

Hongtai can be used for dehumidification storage of various materials such as medicine, food, art, electronic equipment and defense equipment.
In contrast, hygroscopic materials will only absorb moisture, which also will become the hotbed of bacteria and mold. The dehumidifier prevents the growth of bacteria and mold by keeping the relative humidity (RH) in the space below 50%. Under controlled humidity, it can prevent storages from condensation and corrosion.

In skating rinks and curling rinks, ice must maintain the highest possible quality, while maintaining a pleasant indoor climate. The easiest way to achieve this is to use a dehumidifier to adjust the humidity of the places.

When the door of the ice rink is opened and closed, warm air will enter. Which will form condensation and hang on the ceiling. Condensed water drops dripping onto the surface of the ice rink will cause ice surfaces unevenly. At the same time, if the air is too humid, there is a risk of corrosion damage and mildew, causing damage to the equipment and making people feel uncomfortable. The humidity problem of the ice rink can be solved by installing a dehumidifier to reduce the ambient humidity to the required level.
