[0018] like Figure 1-2 As shown, this embodiment provides a humidity control method, comprising the following steps: A surface dehumidification system 200 is provided, and the surface dehumidification system 200 comprises a dehumidification box 2, an air inlet pipe 1 connected to one end of the dehumidification box 2, an air outlet pipe 4 connected to the other end of the dehumidification box 2, and a first fan 3 provided on the transmission path of the air outlet pipe 4, wherein the air outlet pipe 4 leads to the factory building 100, and is used to introduce dry air c after dehumidification treatment by the dehumidification box 2 into the factory building 100. When the humidity in the factory building 100 is too high, the surface dehumidification system 200 is started; the outside air enters the dehumidification box 2 through the air inlet pipe 1, forms dry air c after dehumidification treatment, and is then blown into the factory building 100 by the first fan 3 through the air outlet pipe 4; this process continues until the humidity in the factory building 100 drops below the set value; An underground moisture storage system 300 is provided. The underground moisture storage system 300 includes a water collection well 6, a manhole cover 7 matched with the water collection well 6, a tunnel 8 leading from the water collection well 6 to the factory building 100, and a second fan 9 arranged in the tunnel 8, which is used to create a humid environment, temporarily store humid air, and introduce humid air into the factory building 100. The water collection well 6 is arranged underground, and the moisture therein increases the humidity of the surrounding air through natural evaporation; the manhole cover 7 is designed to prevent the entry of external impurities while maintaining a certain ventilation effect. The tunnel 8 leads from the water collection well 6 to the factory building 100 and serves as a transmission channel for humid air; when the second fan 9 in the tunnel 8 is started, the humid air around the water collection well 6 is sucked in and blown into the factory building 100 through the tunnel 8 to achieve a humidification effect; the setting of the tunnel 8 not only provides a stable source of humid air, but also helps to maintain the humidity and temperature stability of the tunnel 8 through natural ventilation; The underground moisture storage system 300 utilizes the natural humidity and temperature stability characteristics of the underground environment, and stores and maintains a certain amount of humid air through the design of the water collection well 6 and the tunnel 8. When the humidity in the factory 100 needs to be increased, the second fan 9 in the tunnel 8 is started to introduce the humid air into the factory 100, thereby achieving a rapid and uniform humidification effect. Compared with the traditional electric humidification method, this method greatly reduces energy consumption and improves energy efficiency. In addition, the underground moisture storage system 300 consumes almost no additional energy to produce humidified air, but utilizes the humidity resources of the underground natural environment. This method reduces the impact on the environment and is a green and sustainable humidification solution that helps to reduce the carbon footprint of the enterprise. In addition, the underground environment The temperature and humidity are relatively stable and are not drastically affected by external climate changes. Therefore, the underground moisture storage system 300 can provide a stable and reliable humidification effect for the plant 100, reducing production problems and equipment failures caused by humidity fluctuations. Moreover, the underground moisture storage system 300 mainly relies on the natural environment and physical principles to work, without complex mechanical components and wearing parts, which reduces the maintenance cost of the system and extends its service life. It also reduces production losses caused by downtime due to failures. In addition, the water collection well 6 and the tunnel 8 are set underground, which not only saves ground space, but also avoids the space layout problems associated with traditional equipment. This makes the system easier to integrate into the existing industrial plant 100 and improves space utilization. When adjusting the humidity in the plant 100, by controlling the operation of the first fan 3, the outside air enters the plant 100 after being dehumidified by the moisture absorption box 2, so as to achieve the purpose of reducing the humidity of the plant 100. During this period, the air humidity in the plant 100 is monitored in real time. When the measured air humidity is greater than the set humidity, the first fan 3 is continuously operated. When the measured air humidity is less than the set humidity, the first fan 3 is turned off and the second fan 9 is started to introduce the humid air in the tunnel 8 and the water collection well 6, so as to achieve the purpose of increasing the humidity of the plant 100. This control strategy ensures accurate control and rapid response of humidity. In summary, this invention patent achieves efficient, precise and environmentally friendly control of the humidity of the factory building at 100° by combining surface dehumidification with underground moisture storage, providing more stable and suitable environmental conditions for industrial production.

[0019] like Figure 2As shown, in some embodiments, a window 1001 can be set on the wall of the factory building 100, and it is ensured that the window 1001 is set diagonally to the end of the air outlet pipe 4 or the tunnel 8 leading into the factory building 100. The layout of the diagonal window 1001 not only optimizes the air circulation path, but also enhances the natural ventilation effect in the factory building 100. When the first fan 3 blows dry air c into the factory building 100 through the air outlet pipe 4, the diagonal window 1001 helps to form air convection, accelerate the dehumidification process, and reduce the humidity of the factory building 100. Similarly, when the second fan 9 introduces humid air through the tunnel 8, the diagonal window 1001 can also promote uniform air distribution and improve humidification efficiency. The setting of the diagonal window 1001 promotes the circulation and mixing of air in the factory building 100, making the dry air c Dry or humid air can be distributed to the entire space more quickly, reducing the dead corners of humidity control and improving the uniformity and efficiency of humidity control. The air flow in the factory building 100 can also be finely adjusted by adjusting the opening and closing degree of the window 1001, thereby achieving more precise control of the humidity. This adjustment method is suitable for climate changes in different seasons and can meet the special needs of humidity in the production process. Moreover, good ventilation and humidity control are not only conducive to the normal operation of equipment, but also significantly improve the quality of the working environment and the comfort of employees. The diagonal window 1001 system reduces the need for artificial lighting by introducing natural light and fresh air, and also helps to reduce the concentration of indoor pollutants, creating a healthier and more pleasant working environment for employees.

[0020] In some embodiments, the dehumidifying box 2 includes a desiccant storage chamber and an air circulation chamber, wherein the desiccant storage chamber is used to place desiccant to absorb moisture in the air entering the desiccant box 2, while the air circulation chamber allows outside air to pass through and fully contact the desiccant to achieve efficient dehumidification; a replaceable desiccant box is provided in the desiccant storage chamber, which is convenient for regular replacement of desiccant to ensure continuous and stable dehumidification effect; the air circulation chamber is designed as a winding channel structure, which increases the contact time and contact area between air and desiccant, further improving the dehumidification efficiency; in addition, the desiccant box 2 is also equipped with A humidity sensor is provided for real-time monitoring of the humidity of the air after being treated by the moisture absorption box 2 to ensure that the dehumidification effect reaches the expected goal. The separation design of the desiccant containing chamber and the air circulation chamber ensures both the effective utilization of the desiccant and the smooth circulation of the air. The replaceable desiccant box design simplifies the maintenance process and reduces the operating cost. The winding air circulation chamber structure significantly improves the contact efficiency between the air and the desiccant, making the dehumidification more thorough. The addition of the humidity sensor realizes real-time monitoring of the dehumidification effect and ensures the precise control of the humidity in the plant 100.

[0021] like Figure 1As shown in or 2, in some embodiments, a solar water collection system 400 can be set up. The solar water collection system 400 includes a water collection tank 12 for collecting rainwater, a water pipe 14 connected to the output end of the water collection tank 12, and a solar heating mechanism 13 arranged on the transmission path of the water pipe 14. The water pipe 14 passes through the desiccant box 2 and is connected to the drain pipe 15. The water collection tank 12 is configured to efficiently collect rainwater and transport the rainwater to subsequent processing links through the water pipe 14. The solar heating mechanism 13 uses solar energy to heat the rainwater in the water pipe 14 to increase the temperature of the rainwater, which helps to reduce the burden of the desiccant in the desiccant box 2 and improve the dehumidification efficiency. The design of the water pipe 14 passing through the desiccant box 2 allows the heated rainwater to directly exchange heat with the air in the desiccant box 2, further enhancing the dehumidification efficiency. Wetting effect, the drain pipe 15 is used to discharge the rainwater after heat exchange out of the system to ensure the continuous and stable operation of the system. By integrating the solar water collection system 400, the effective use of natural resources is realized and the energy consumption of the system is reduced. The application of the solar heating mechanism 13 not only increases the temperature of the rainwater, but also helps to reduce the use of desiccant and reduce operating costs. The design of the water pipe 14 running through the moisture absorption box 2 realizes the effective conversion of heat energy and humidity, and further improves the dehumidification efficiency. In addition, the introduction of this system also enhances the environmental protection of the entire humidity control system, which is in line with the concept of sustainable development. In summary, the setting of the solar water collection system 400 not only improves the performance of the humidity control system, but also reduces energy consumption and operating costs, providing a greener and more efficient humidity control solution for industrial production; like Figure 2 As shown, in some embodiments, a sand pit 5 can be dug on one side of the water collection well 6, and the sand pit 5 can be filled with fine sand. The sand pit 5 is configured to directly collect rainwater. The fine sand in the sand pit 5 has good water absorption and filtration properties, and can quickly absorb and store moisture in the rainwater. Subsequently, the moisture is gradually released and infiltrated into the water collection well 6 through the natural infiltration of the fine sand, increasing the water volume of the water collection well 6 and the humidity of the surrounding air. The fine sand can also perform preliminary filtering of the rainwater to remove impurities and pollutants therein, thereby ensuring the cleanliness of the water quality in the water collection well 6. The existence of the sand pit 5 not only expands the water collection area and water storage capacity of the water collection well 6, but also makes the underground moisture storage system The system 300 can store more water and humid air, and also improves the natural infiltration and moisture storage capacity of the system. When humidification is needed in the factory building 100, the second fan 9 is started, and the rich humid air stored in the water collection well 6 and the surrounding sand pit 5 can be sucked into the tunnel 8 and blown into the factory building 100, which significantly improves the humidification efficiency and humidification amount, and provides a faster and more uniform humidification effect for the factory building 100. In addition, a permeable cover, such as a permeable geotextile, can be provided on the upper part of the sand pit 5, which not only prevents larger external impurities from entering the sand pit 5, but also maintains the ventilation permeability and natural infiltration capacity of the sand pit 5, which helps to maintain the stability of the humidity in the sand pit 5 and the water collection well 6.

[0022] like Figure 2 As shown, in some embodiments, the drain pipe 15 can be extended to just above the sand pit 5, and a number of sprinkler heads 16 can be provided on the drain pipe 15, and the sprinkler heads 16 are configured to spray the cool water flowing out of the drain pipe 15 evenly into the sand pit 5. Through this design, the cool water in the drain pipe 15 that has undergone heat exchange treatment can be effectively utilized, which not only improves the wetness of the sand pit 5, but also achieves uniform wetting of the fine sand in the sand pit 5. The uniform spraying effect of the sprinkler heads 16 ensures that the humidity distribution in each area of ​​the sand pit 5 is more balanced, avoids local over-wetting or over-drying, and provides a more stable and uniform wet environment for the sand pit 5. In addition, by adjusting the spraying amount and spraying time of the sprinkler heads 16, the humidity level in the sand pit 5 can be further controlled, thereby achieving fine adjustment of the humidity of the underground moisture storage system 300.

[0023] like Figure 1 As shown, when the air humidity in the factory building 100 needs to be lowered, the surface wet air b is converted into dry air c after being processed by the surface dehumidification system 200 and input into the factory building 100; when the air humidity in the factory building 100 needs to be increased, the underground wet air d is transmitted from the underground moisture storage system 300 to the factory building 100; when the desiccant in the desiccant box 2 needs to be regenerated, the hot water e heated by the solar water collection system 400 will flow through the desiccant box 2 in the surface dehumidification system 200, and heat will be exchanged with the desiccant during the flow to achieve the regeneration of the desiccant. After the heat exchange, the desiccant restores its good moisture absorption function, and the hot water e is converted into cold water f, which is discharged into the underground moisture storage system 300 to increase or maintain the humidity of the underground moisture storage system 300.

[0024] like Figure 2As shown, in some embodiments, a waterproof layer 10 can be laid on the inner wall of the water collection well 6 and the tunnel 8, and a plurality of openings 11 can be opened at the position where the waterproof layer 10 is close to the sand pit 5. By laying the waterproof layer 10 on the inner wall of the water collection well 6 and the tunnel 8, the penetration and damage of groundwater and other external water sources to the system can be effectively prevented, thereby improving the overall stability and safety of the system, which helps to extend the service life of the system and reduce maintenance and repair costs. The design of the openings 11 allows moisture and humid air in the sand pit 5 to penetrate into the water collection well 6 and the tunnel 8, thereby increasing the moisture storage capacity of the system, which enables the system to provide more in the dry season or when humidification is needed. More stable humid air meets the humidity requirements of the factory 100. By adjusting the size and number of the openings 11, the moisture and air exchange rates between the sand pit 5 and the water collection well 6 and the tunnel 8 can be finely controlled, thereby achieving more precise and flexible control of the humidity of the factory 100, which helps to maintain the stability and consistency of the humidity in the factory 100, improve product quality and employee comfort. The design of the waterproof layer 10 and the openings 11 enables the moisture in the sand pit 5 to be effectively utilized and enter the water collection well 6 and the tunnel 8 through natural infiltration, thereby realizing the recycling of water resources, which helps to reduce dependence on external water sources and improve the environmental protection and sustainability of the system.
