[0041] Compared with the prior art, the present application has obvious advantages and beneficial effects, which are embodied in the following aspects:

[0042] 1. The variable space assembly type pressurized building in the present application is composed of variable space units, each of which is composed of an airtight pressure-bearing space and a combined pressure-changing space spliced together, and both the airtight pressure-bearing space and the combined pressure-changing space are three-dimensional rectangular closed space structures enclosed by an airtight pressure-bearing structure, and the core of the airtight pressure-bearing structure is a pressure-bearing airtight layer, and a fireproof layer and a thermal insulation layer are arranged inside and outside the pressure-bearing airtight layer to provide fireproof and thermal insulation functions, thereby forming the airtight pressure-bearing structure, which ensures the strength and airtightness of the structure and guarantees the airtightness of the variable space unit. While ensuring airtightness, by increasing the combined pressure-changing space, the integrated equipment system and other objects are placed in the combined pressure-changing space, avoiding the space occupation of the airtight pressure-bearing space, and increasing the actual space occupation area of the airtight pressure-bearing space. The air inlet and outlet device is located on the airtight pressure-bearing space and connected with the integrated equipment system, which is used to control and adjust the internal environment parameters, such as air purification, fresh air inlet and outlet, etc.; the integrated equipment system can adjust the airtight pressure-bearing space according to the set equivalent altitude, and enter the normal use state after reaching the set pressure, ensuring the stability and comfort of the internal environment; and the airtight pressure-bearing door is installed on the airtight pressure-bearing structure, which is used for the entry and exit of users on one hand, and ensures the airtightness of the space when opening and closing on the other hand. In this way, through the structural arrangement of the variable space unit, the building components or modules can be prefabricated in the factory, and then assembled and installed on site, realizing a fast, efficient and repeatable building process. This building method has the advantages of low construction cost, small design difficulty, good process connection effect, energy saving and environmental protection, etc., and can expand the space according to actual needs; through the adjustment of the integrated equipment system, the pressurized building can adapt to different environmental conditions, such as altitude change, enhancing the adaptability and practicality of the building, and ensuring the safety, comfort and flexibility of the variable space.

[0043] 2. The combined connection mode of the combined pressure-changing space not only can form a public corridor to realize the intermediate transfer channel for entering and exiting different airtight pressure-bearing spaces, but also can realize sealed connection through the installation of airtight doors and windows without occupying additional space, ensuring the sealing between the public corridor and the airtight pressure-bearing space, and further making the airtight pressure-bearing space, the combined pressure-changing space and the external environment present a transition pressure environment from high to low in turn.

[0044] 3. The airtight pressure-bearing door and window structure or the non-airtight pressure-bearing door and window structure can be switched on the combined pressure-changing space to facilitate pressure-bearing and non-pressure-bearing conversion, which allows quick switching between airtight and non-airtight structures according to different use requirements and environmental conditions to adapt to more different use scenarios, improving the adaptability and flexibility of the pressurized building; in addition, the switchable structure design simplifies the maintenance and operation process, making the management of the pressurized building more convenient, and also reducing the maintenance cost.

[0045] 4. The article delivery device is arranged between the airtight pressure-bearing space and the combined pressure-changing space, and is used for delivering small articles between the airtight pressure-bearing space and the combined pressure-changing space when there is a pressure difference between the indoor and outdoor environments. The device allows safe delivery of articles without damaging the airtightness of the airtight pressure-bearing space, and avoids contamination of the indoor environment by foreign objects after long-term use, thereby improving the air cleanliness of the indoor environment.

[0067] In the case of no conflict, the above embodiments and features in the embodiments can be combined with each other.

[0068] Please refer to Figures 1-3As shown, the variable space prefabricated pressurized building provided by the embodiment of the present application comprises at least one variable space unit 1, each of which comprises an airtight pressure space 11 and a combined pressure space 12, which are both enclosed by an airtight pressure structure 2 in a cuboid rectangular closed space, and the combined pressure space 12 is assembled and connected on one side of the airtight pressure space 11 in the width direction;

[0069] The airtight pressure structure 2 comprises an airtight pressure layer 21, and a fireproof layer 22 and a thermal insulation layer 23 installed inside and outside the airtight pressure layer 21;

[0070] The airtight pressure structure 2, which is shared by the airtight pressure space 11 and the combined pressure space 12, is further provided with an air inlet and exhaust device 3 and a first airtight pressure door 41, and the air inlet and exhaust device 3 is further provided with an integrated equipment system 5 which is in communication with the air inlet and exhaust device 3 on one side inside the airtight pressure space 11, and the integrated equipment system 5 is adapted to control and adjust the environmental parameters inside the airtight pressure space 11;

[0071] The side of the combined pressure space 12 away from the airtight pressure space 11 is adapted to install an airtight pressure door and window structure or a non-airtight pressure door and window structure, so that the combined pressure space 12 can be converted for pressure.

[0072] Specifically, the variable space prefabricated pressurized building is composed of variable space units 1, each of which is composed of an airtight pressure space 11 and a combined pressure space 12 spliced together, and both the airtight pressure space 11 and the combined pressure space 12 are cuboid rectangular closed space structures enclosed by an airtight pressure structure 2, and the core of the airtight pressure structure 2 is an airtight pressure layer 21 which ensures the strength and airtightness of the structure, and a fireproof layer 22 and a thermal insulation layer 23 are provided inside and outside the airtight pressure layer 21 to provide fireproof and thermal insulation functions, thereby forming the airtight pressure structure 2 and ensuring the airtightness of the variable space unit 1. The air inlet and exhaust device 3 is located on the airtight pressure space 11 and connected with the integrated equipment system 5, which is used to control and adjust the internal environmental parameters such as air purification and fresh air inlet and outlet; the integrated equipment system 5 can adjust the airtight pressure space 11 according to the set equivalent altitude, and enter the normal use state after reaching the set pressure, thereby ensuring the stability and comfort of the internal environment; and the first airtight pressure door 41 is installed on the airtight pressure structure 2, which is used for the entry and exit of users on one hand, and ensures the airtightness of the space when opening and closing on the other hand.

[0073] Thus, through the structural arrangement of the variable space unit 1, building components or modules can be prefabricated in the factory, and then assembled and installed on site, realizing a fast, efficient and repeatable building process. This building method has the advantages of low construction cost, small design difficulty, good process connection effect, energy saving and environmental protection, and can expand the space according to actual needs; through the adjustment of the integrated equipment system 5, the pressurized building can adapt to different environmental conditions, such as changes in altitude, enhancing the adaptability and practicality of the building, and ensuring the safety, comfort and flexibility of the variable space.

[0074] Further, please refer to Figure 1 As shown in the figure, the prefabricated pressurized building of the variable space further comprises an article transfer device 6, which is installed between the airtight pressure-bearing space 11 and the combined variable pressure space 12. The article transfer device 6 is provided on the airtight pressure-bearing structure 11 shared by the airtight pressure-bearing space 11 and the combined variable pressure space 12, and is located on one side of the first airtight pressure-bearing door 41.

[0075] When the non-airtight pressure-bearing door and window structure is installed on the side of the combined variable pressure space 12 away from the airtight pressure-bearing space 11, the article transfer device 6 is adapted to transfer articles from the combined variable pressure space 12 to the airtight pressure-bearing space 11.

[0076] Specifically, in this embodiment, the article transfer device 6 is installed between the airtight pressure-bearing space 11 and the combined variable pressure space 12. In this embodiment, the article transfer device 6 is provided on the airtight pressure-bearing structure 2 shared by the two, considering the characteristics of the airtight pressure-bearing space 11 needing to have high airtightness to prevent air exchange between different areas, causing pollution.

[0077] As a preferred mode of this embodiment, the article transfer device 6 is realized by mechanical and inflation double-sealing design. For example, high-elasticity inflatable sealing rings are installed on the inner and outer doors, and then a double-layer sealing band is formed between the door and the door frame through a pressing mechanism, achieving higher airtightness. The inner and outer doors of the article transfer device use interlocking devices, so that the two doors cannot be opened at the same time during operation, preventing air flow between the rooms and acting as an airlock.

[0078] When the non-airtight pressure-bearing door and window structure is installed on the side of the combined variable pressure space 12 away from the airtight pressure-bearing space 11, the design of the article transfer device allows the transfer of articles from the combined variable pressure space to the airtight pressure-bearing space, which requires the transfer device to be designed to adapt to different pressure environments and maintain airtightness.

[0079] Further, please refer to Figure 1 As shown in the figure, the airtight pressure-bearing structure 2 further comprises evenly distributed expansion connecting skeletons 24, and the adjacent variable space units 1 are transversely and longitudinally spliced through the expansion connecting skeletons 24.

[0080] Specific to the embodiment, the airtight pressure-bearing structure 2 is a key part of the prefabricated pressurized building, which needs to have sufficient strength and airtightness to maintain the stability of the internal pressure. The expansion connecting framework 24 is evenly distributed in this structure, which plays a role in strengthening and connecting.

[0081] Considering that the variable space unit 1 needs to be reconfigured and moved according to space requirements, this variable space unit 1 is a core feature of prefabricated buildings, and through the expansion connecting framework 24, these variable space units 1 can be flexibly connected horizontally and vertically, so as to realize the rapid adjustment and change of space, and the connecting framework 24 ensures the stability and airtightness of the structure.

[0082] Therefore, the airtight pressure-bearing structure 2 enables the pressurized building space to be quickly adjusted according to the use requirements, improving the adaptability and flexibility of the pressurized building. At the same time, due to the use of modular and splicing technology, the construction efficiency is improved, the project cycle is shortened, and the resource and energy consumption is reduced.

[0083] Further, a plurality of variable space units 1 are parallel and juxtaposed along the length direction to form a hall side wall 13, and the combination variable pressure space 12 of the hall side wall 13 is connected to form a public corridor 19.

[0084] Specific to the embodiment, please refer to Figure 2 As shown in the figure, a plurality of variable space units 1 are parallel and juxtaposed along the length direction to form a first hall side wall 131 and a second hall side wall 132, and the first hall side wall 131 and the second hall side wall 132 are mutually enclosed to form a structure form with a middle hall, for example, two second hall side walls 132 are connected vertically at both ends of the first hall side wall 131, and a hall is formed in the middle.

[0085] At this time, the expansion direction of the first hall side wall 131 and the second hall side wall 132 is perpendicular to each other, and the combination variable pressure space 12 of the first hall side wall 131 is connected to form a first public corridor 191, and the combination variable pressure space 12 of the second hall side wall 132 is connected to form a second public corridor 192, and the first public corridor 191 and the second public corridor 192 are connected in series at the end of the first public corridor 191 and the second public corridor 192, so that the first public corridor 191 and the second public corridor 192 are connected.

[0086] During splicing, the pressure-bearing building needs to maintain the airtightness of the interior to reduce the equivalent altitude and protect the health of the occupants. Therefore, the airtightness at the splicing joint is connected through the expansion connecting framework 24 to ensure the stability of the internal air pressure of the pressurized building.

[0087] Further, please refer to Figure 2As shown, the prefabricated pressure-boosting building of variable space further comprises a staircase unit module 15 and a lobby module 16, wherein:

[0088] The staircase unit module 15 is connected between two adjacent variable space units 1 in the length direction of the variable space unit 1, and a plurality of combined variable pressure spaces 12 are arranged in parallel on both sides of the staircase unit module 15 to form a public corridor 19 on both sides of the staircase unit module 15 and communicate with the staircase unit module 15;

[0089] The lobby module 16 is arranged on the side of the staircase unit module 15 close to the variable space unit 1, and the lobby module 16 communicates with the staircase unit module 15;

[0090] The variable space unit 1 is adapted to be expanded in the longitudinal direction by the staircase unit module 15 to form a multi-story space structure.

[0091] In this embodiment, the staircase unit module 15 is connected between two adjacent variable space units 1 in the length direction of the variable space unit 1, serving as a connection and longitudinal expansion, and a plurality of combined variable pressure spaces 12 are arranged in parallel on both sides of the staircase unit module 15 to connect the combined variable pressure spaces 12 in each variable space unit 1 in series to form a public corridor 19. In this way, the staircase unit module 15 can be accessed into the public corridor 19, and then into the corresponding airtight pressure-bearing space 11 through each combined variable pressure space 12, so that the staircase unit module 15 plays a key role in vertical traffic and space connection in the multi-story pressure-boosting building.

[0092] The lobby module 16 is arranged on the side of the staircase unit module 15 close to the variable space unit 1 and communicates with the staircase unit module 15, which serves to provide a transition space for personnel flow and management, and also serves as a facade of the building to provide circulation and preliminary service functions.

[0093] It can be understood that the variable space unit 1 can be expanded in the longitudinal direction by the staircase unit module 15 to form a multi-story space structure to adapt to different use requirements and functional changes.

[0094] In addition, by prefabricating the staircase unit module 15 and the lobby module 16 in the factory and then assembling and installing them on site, a fast, efficient and repeatable building process is achieved, and this building method has the advantages of low construction cost, small design difficulty, good process connection effect, energy saving and environmental protection. Since the staircase unit module 15 and the lobby module 16 have been produced in the factory, on-site assembly and installation can be quickly carried out, greatly shortening the construction period, and also realizing the recycling of materials and reducing carbon emissions and environmental pollution during the construction process.

[0095] Further, please refer to Figure 3As shown, the prefabricated pressurized building of variable space further comprises a conversion connection module 17 and an elevator unit module 18, wherein:

[0096] The conversion connection module 17 is arranged between the combined variable pressure spaces 12 close to each other along the longitudinal extension direction of the variable space unit 1, and the conversion connection module 17 is in communication with the public corridor 19; in this way, the conversion connection module 17 can become a key node connecting different spaces, and allows the variable space to be extended and connected in the longitudinal direction. The conversion connection module 17 is also in communication with the public corridor 19, which can enhance the space flow and functionality inside the building, and provide more flexible space conversion and usage.

[0097] The elevator unit module 18 is arranged on the side of the conversion connection module 17 away from the public corridor 19, and the elevator unit module 18 is in communication with the conversion connection module 17, and the elevator unit module 18 also leans against the hall side wall 13; this layout makes the elevator unit module 18 become the core of the vertical communication of the multi-storey pressurized building, and solves the flow problem of the users moving vertically in the multi-storey space structure.

[0098] The variable space unit 1 is extended in the longitudinal direction by the conversion connection module 17 and the elevator unit module 18 to form the multi-storey space structure.

[0099] Therefore, through the arrangement of the conversion connection module 17 and the elevator unit module 18, the variable space unit 1 can be extended in the longitudinal direction to form a multi-storey space structure, which improves the space flexibility and variability of the building and allows the internal space layout to be adjusted according to needs.

[0100] In addition, since the conversion connection module 17 and the elevator unit module 18 are prefabricated in the factory, only assembly is required on site, which can greatly shorten the construction period and improve the construction efficiency.

[0101] Further, please refer to Figure 3 As shown, the integrated equipment system 5 comprises an air pressurization module 51, a strong and weak current module 52, and an environment detection module 53;

[0102] The air pressurization module 51 is adapted to pump compressed air into the air-tight pressure-bearing space 11 to increase the air pressure and oxygen concentration in the air-tight pressure-bearing space 11;

[0103] The strong and weak current module 52 is used to provide power and signal transmission to the air-tight pressure-bearing space 11;

[0104] The environment detection module 53 is used to detect the environmental parameters in the air-tight pressure-bearing space 11 in real time.

[0105] Specifically, the main function of the air pressurization module 51 is to pump compressed air into the airtight pressurized space 11 to increase the air pressure and oxygen concentration in the space. By continuously pumping compressed air, the air pressurization module 51 can maintain the air pressure in the airtight pressurized space 11 at an appropriate level, while the increased oxygen concentration helps to improve the work efficiency and physical health of personnel in high-altitude areas. This module is particularly important for maintaining a comfortable environment for personnel in an airtight space, especially in high-altitude or enclosed environments, where the occurrence of hypoxia can be prevented by increasing the oxygen concentration.

[0106] The strong and weak current module 52 is responsible for providing necessary power and signal transmission to the airtight pressurized space 11, which is the key to power supply and communication in the variable space unit 1, ensuring the normal operation of the equipment and the smooth flow of information.

[0107] The environmental detection module 53 is used to detect environmental parameters in the airtight pressurized space 11 in real time, such as temperature, humidity, harmful gas concentration, etc. This module collects data through sensors and monitoring devices to provide decision support for environmental control. Through real-time monitoring of environmental parameters in the airtight pressurized space 11, the environmental detection module 53 can timely detect environmental changes and take corresponding measures, such as adjusting temperature and humidity, ventilation, etc., to ensure the comfort and safety of the space. This real-time monitoring and control is particularly important for closed spaces, which can effectively prevent the impact of environmental factors on personnel health and equipment operation in high-altitude areas.

[0108] As a preferred mode of the present embodiment, the integrated device system 5 can also include a water treatment module 54, an energy module 55, and a temperature and humidity adjustment module 56, wherein the water treatment module 54 is used to provide water to the airtight pressurized space 11 and treat used water to prevent environmental pollution; the energy module 55 includes power supply, energy management and energy storage system, which is used to convert external energy (such as electricity, heat, etc.) into energy suitable for building use and effectively manage it, improve energy utilization efficiency, reduce energy consumption, and realize sustainable use of energy through intelligent energy management and scheduling; the temperature and humidity adjustment module 56 works based on the principle of temperature and humidity sensors, measures the temperature and humidity of the surrounding environment, and converts these data into digital signals for output to other devices or systems, to maintain the comfort of the indoor environment.

[0109] For example, the temperature and humidity adjustment module 56 creates a healthy and comfortable living environment by automatically adjusting the indoor temperature and humidity of the airtight pressurized space 11. The temperature and humidity adjustment module 56 in the present embodiment includes a detection part and an adjustment display part, which can automatically adjust according to environmental changes to maintain stable temperature and humidity.

[0110] In summary, the integrated equipment system 5 serves as a control center, providing clean water source, efficient energy supply and comfortable indoor environment for the airtight pressure space 11, improving the comfort and functionality of the residence.

[0111] Further, please refer to Figure 3 As shown, the variable space prefabricated pressurized building further comprises a ventilation device 57 and a pressure relief device 58, wherein:

[0112] The ventilation device 57 is arranged on the airtight pressure structure 2 of the airtight pressure space 11, and the ventilation device 57 is adapted to be opened when the airtight pressure space 11 is in an unpressurized state, so that the airtight pressure space 11 is in an air flow state. The ventilation device 57 usually includes a fan, a filter, a control system and the like, wherein the fan is responsible for generating power to push air flow; the filter is used to purify the air entering the airtight space and remove dust and harmful particles; the control system automatically adjusts the fan speed and operation mode according to the indoor and outdoor air quality, temperature and other parameters, maintains the indoor air quality of the airtight pressure space 11 by introducing outdoor fresh air and discharging contaminated air in the airtight pressure space 11.

[0113] The pressure relief device 58 is installed on the airtight pressure structure 2 of the airtight pressure space 11, and the pressure relief device 58 is electrically connected with the integrated equipment system 5. When the pressure in the airtight pressure space 11 exceeds the design value, the pressure is quickly released to protect the building structure of the airtight pressure space 11 from being damaged.

[0114] Preferably, the pressure relief device 58 can be power-free or power-driven, the power-free type relies on pressure regulation driving components, and the power-driven type is provided with pressure detection devices and electric driving components.

[0115] Therefore, the ventilation device 57 and the pressure relief device 58 can ensure the air quality and structural safety of the airtight pressure space 11 in different states in the variable space prefabricated pressurized building, and improve the comfort and reliability of the pressurized building.

[0116] Further, please refer to Figure 3 As shown, the pressure airtight layer 21 is an important component of the variable space prefabricated pressurized building, and the pressure airtight layer 21 in the embodiment is welded or spliced by plates and columns, which not only can ensure the strength and airtightness of the structure to withstand the pressure caused by the internal and external pressure difference, but also can maintain the stability of the internal environment.

[0117] When the welding method is adopted, the plates and columns are connected by welding to form a continuous airtight pressure structure 2. During the welding process, the quality of the weld is required to be guaranteed to ensure that there are no pores and cracks, so as to maintain the integrity and airtightness of the structure.

[0118] When using splicing, high-strength bolts or special splicing plates can be used, and during splicing, the close contact of the connection part needs to be ensured to ensure the continuity and air tightness of the structure.

[0119] It should be particularly pointed out that the main function of the pressure-tight layer 21 is to withstand the internal and external pressure difference and maintain the stability of the structure. Therefore, whether it is welded or spliced, it is necessary to ensure that the structure does not be damaged when it withstands the design pressure.

[0120] Another embodiment of the present application also provides a method for using the prefabricated pressurized building with variable space as described above, the using method comprising the following steps:

[0121] Step S 100 : Determine the pressure state of the combined variable pressure space 12 in the variable space unit 1 and the state of personnel entering and leaving the air-tight pressure-bearing space 11.

[0122] In this step, by monitoring the pressure state of the combined variable pressure space 12 in the variable space unit 1 and determining the state of personnel entering and leaving the air-tight pressure-bearing space 11, it can be ensured that the personnel entering and leaving operation is carried out under safe and comfortable pressure conditions. This involves pressure sensors and monitoring systems that can real-time feedback pressure data to facilitate the corresponding adjustment of the user when entering and leaving the air-tight pressure-bearing space 11.

[0123] Step S 200 : When entering the multi-layer space structure formed by the combination of the variable space unit 1, the public corridor formed by the combined variable pressure space 12 can be entered through the stair unit module 15 and the lobby module 16.

[0124] In this step, when entering the multi-layer space structure formed by the combination of the variable space unit 1, the public corridor formed by the combined variable pressure space 12 is entered through the stair unit module 15 and the lobby module 16, so that through the space layout and modularization of the pressurized building, the user can conveniently move between different layers of space.

[0125] Step S 200 : When the combined variable pressure space 12 is in a normal pressure state and the air-tight pressure-bearing space 11 is to be used, open the normal pressure door of the combined variable pressure space 12 to enter the combined variable pressure space 12;

[0126] Control the integrated equipment system 5 to reduce the pressure in the air-tight pressure-bearing space 11 to the same as the combined variable pressure space 12, and close the air-tight pressure-bearing door after entering the air-tight pressure-bearing space 11;

[0127] Control the integrated equipment system 5 to input the set equivalent altitude to pressurize the air-tight pressure-bearing space 11, and enter the normal use state after reaching the set pressure.

[0128] In this step, the pressure between the airtight pressure space 11 and the combined pressure space 12 is adjusted by controlling the integrated equipment system 5 to ensure pressure balance before opening and closing the airtight door. This process requires precise pressure control and reliable operation of the airtight door to maintain airtightness and safety.

[0129] When entering the airtight pressure space 11, the pressure of the airtight pressure space 11 is increased to the set pressure by inputting the set equivalent altitude, and the space enters the normal use state, ensuring that the pressure environment in the space meets the specific use requirements. When leaving the airtight pressure space 11, pressure balance, airtight door operation, etc. are also involved to ensure the safety of personnel leaving while maintaining the airtightness of the space.

[0130] Step S 300 When the combined pressure space 12 is in a pressurized state and the airtight pressure space 11 is to be entered for use, the integrated equipment system 5 is controlled to reduce the pressure in the combined pressure space 12 to the same as the outdoor, open the second airtight pressure door 42 on the combined pressure space 12, and close the second airtight pressure door 42 after entering the combined pressure space 12.

[0131] The integrated equipment system 5 is controlled to increase the pressure in the combined pressure space 12 to the same as the pressure in the airtight pressure space 11, open the first airtight pressure door 41 to enter the airtight pressure space 11, and close the first airtight pressure door 41.

[0132] The integrated equipment system 5 is controlled to input the set equivalent altitude to increase the pressure of the airtight pressure space 11, and the space enters the normal use state after reaching the set pressure.

[0133] In this step, since the combined pressure space 12 is in a pressurized state, when entering the airtight pressure space 11 for use, the pressure in the combined pressure space 12 is first adjusted to the same as the outdoor by the integrated equipment system 5, and then the pressure balance between the combined pressure space 12 and the airtight pressure space 11 is adjusted by the integrated equipment system 5, and the airtight pressure space 11 can be entered for use.

[0134] Step S 400 When leaving the airtight pressure space 11, the integrated equipment system 5 is controlled to increase the pressure in the combined pressure space 12 to balance with the pressure in the airtight pressure space 11, open the first airtight pressure door 41 on the airtight pressure space 11, enter the combined pressure space 12, and close the first airtight pressure door 41 on the airtight pressure space 11.

[0135] The integrated equipment system 5 is controlled to reduce the pressure in the combined pressure space 12 to the same as outside, open the second airtight pressure door 42 on the combined pressure space 12, and normally exit the combined pressure space 12.

[0136] In this step, the process of exiting the airtight pressure space 11 is introduced, which also includes pressure balancing, airtight door operation, etc., to ensure the safety of personnel exiting while maintaining the airtightness of the space. This step S 400 is completely opposite to the regulation process of step S 300 .

[0137] In summary, the use method of the prefabricated pressure-boosting building of the variable space realizes the safe, comfortable and convenient entry and exit of personnel from the airtight pressure space 11 through precise pressure control, airtight door operation and control operation of the integrated equipment system 5, while ensuring the environmental adaptability of the space.

[0138] It should be particularly pointed out that the order of step S 200 and step S 300 may be adjusted as needed, and the method does not make any limitation on this.

Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present disclosure.
