Special dehumidifier for underground works, dehumidification construction scheme for underground works

Household Dehumidifier_161 Series

The special dehumidifier for underground works and the news of the dehumidification construction scheme for underground works are well known. In today's peaceful times, some civil air defense projects that are usually idle around us are mainly used for commercial, entertainment, hotels, storage, parking and other public welfare undertakings to maximize its social benefits. Of course, its usual management and maintenance work is also very important; As most civil air defense projects are underground or in the mountains, humidity is unavoidable! Therefore, the moisture-proof and dehumidification of underground works is the top priority of management and maintenance


So, how to effectively dehumidify and moistureproof underground works? Let's see the following analysis: generally, the common problems of moisture and condensation in civil air defense underground projects will directly affect the quality and progress of civil engineering, mechanical and electrical engineering and decoration projects. Common problems such as: damp and mildewed walls, ponding on the ground, dew and rust of pipes, corrosion of metal fittings, damp and mildewed ceiling... These problems often cause the safety of civil air defense underground projects, cause quality and safety hazards, and affect the development of subsequent processes

In addition, some large-scale civil air defense underground projects are installed with communication equipment, protective equipment, wind, water and electricity equipment, fire protection and intelligent control equipment, office equipment, and project decoration. These equipment and decoration have different requirements for environmental humidity, especially electronic equipment. Generally, the internal humidity of the project shall be controlled below 75% RH, and the environmental humidity of important equipment shall be controlled below 70% RH


When the internal humidity of the project is too high, small "condensation" water drops on the wall and ground will be formed, which will cause rust of iron pieces of various equipment and functional degradation, mildew and discoloration of decoration, and affect work and life due to the humid environment; The most serious is the "condensation" of water on the wall and ground, which causes serious corrosion of various equipment and makes it unable to work normally, the insulation performance of power supply lines and electrical equipment declines and cannot function normally, the short circuit of various electrical lines causes safety accidents, and the humidity of the environment affects the normal work and life of personnel in the project

For this reason, it is necessary to control the entry of external moisture sources. The method of sealing and blocking shall be adopted to cut off all personnel entrances and exits, antenna wellheads, vents, air inlet and exhaust pipe openings, through wall cable pipe holes, antenna feeder holes, etc. connected with the outside of the project in the wet season every year, so as to prevent external moist air from entering the project and ensure that the internal humidity of the project is not affected by external humidity changes. It is also necessary to reduce the air humidity inside the project. Usually, the fixed and mobile dehumidification equipment is opened regularly to reduce humidity. Especially in the humid season every year, it takes a long time to open the dehumidification equipment to reduce the humidity to the required humidity standard

◎ Precautions for model selection -- The dehumidification capacity and model of dehumidifier are scientifically calculated mainly according to the volume of the used environment space, the size of fresh air volume, the humidity requirements required by the space environment and other specific values. In addition, it should be noted that the relative humidity of the environment is related to the temperature of the environment. The higher the temperature is, the faster the humidity will evaporate. On the contrary, the worse the effect will be. Therefore, when configuring the dehumidifier, you need to select the type under the guidance of professionals, so that you can select the dehumidifier that is most suitable for you

Core tips: It is understood that the Code for Design of Civil Air Defense Works stipulates that the standard of indoor temperature and humidity for civil air defense works in peacetime is: when the temperature in summer does not exceed 26~28 ℃, the relative humidity should not exceed 70~80% RH; if there are special requirements for emergency rooms, operating rooms, etc., the relative humidity should be 50~70% RH. When designing ventilation and air conditioning, it is necessary to calculate the heat and humidity load, so as to determine the air intake, dehumidification volume, exhaust volume, etc., so as to adopt appropriate ventilation and air conditioning design

However, many designers of civil air defense underground works have not gone through strict calculation, but choose ventilation and air conditioning equipment based on experience, which leads to the equipment can not meet the needs, resulting in low temperature inside the civil air defense underground works in summer, large temperature difference between inside and outside, causing water droplets on the walls. Such a low temperature and humid environment will seriously affect everyone's health. For this reason, it is very necessary to configure dehumidifiers of corresponding power or number to conduct scientific and reasonable dehumidification if we want to do well in moisture-proof and humidity control in civil air defense underground projects

As for the dehumidifier specially used for underground works, all the contents of the dehumidification construction scheme for underground works are provided by Parkoo Electric Appliance. Through the above, I mainly introduced some methods for underground works' moisture-proof. I hope you can learn about them as a reference. In the future construction and design of underground works, moisture-proof and dehumidification measures should be taken, I hope everyone can carry out the moisture-proof work of the underground project through reasonable methods, and I believe that it will certainly make the underground project have a good moisture-proof effect
