Description

Technical Field

[0001] The present invention relates to the field of control methods, and more particularly to an energy-saving dehumidification control method for underground garages. Background Art

[0002] Dehumidification of underground garages refers to taking a series of measures to reduce and control the humidity level in the underground garage in a specific environment to maintain a dry, comfortable and safe environment in the garage.

[0003] The main reasons for the humidity in underground garages include groundwater seepage, poor drainage systems, poor ventilation, and climatic factors. These factors cause the humidity in the garage to increase, which not only affects the maintenance of vehicles and equipment, but may also cause problems such as wall mildew and metal rust.

[0004] Therefore, during the dehumidification process of underground garages, a variety of different dehumidification devices will be used, and during the dehumidification process, dehumidification control methods will be used.

[0005] The existing dehumidification control methods have poor dehumidification effects and single dehumidification methods, which have a certain impact on the use of dehumidification control methods. Therefore, an energy-saving dehumidification control method for underground garages is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is: how to solve the problems of the existing dehumidification control methods, such as poor dehumidification effects and single dehumidification methods, which have a certain impact on the use of dehumidification control methods, and provide an energy-saving dehumidification control method for underground garages.

[0007] The present invention solves the above technical problems through the following technical solutions. The present invention includes the following steps:

[0008] Step 1: First, conduct a preliminary evaluation, including environmental evaluation and equipment selection.

[0009] Step 2: Establish a monitoring system to monitor temperature and humidity and analyze the monitoring data.

[0010] Step 3: When abnormalities are found in the analysis of the monitoring data, give dehumidification prompts and perform dehumidification control.

[0011] Step 4: Regularly maintain and manage, monitor the status of the underground garage, and perform maintenance and management.

[0012] Furthermore, the environmental evaluation process of Step 1 is as follows:

[0013] S1: Conduct temperature and humidity monitoring. Use temperature and humidity monitoring instruments to set monitoring points at different positions in the underground garage (such as the entrance, exit, central area, corners, etc.).

[0014] Continuously record the temperature and humidity data within a preset duration (such as one week or one month), and analyze the temperature and humidity data to obtain the temperature and humidity change trends and distribution characteristics of the underground garage.

[0015] S2: Ventilation condition assessment. Collect the number of ventilation openings, exhaust openings, inlet positions and sizes in the underground garage, and evaluate the effectiveness of the ventilation system.

[0016] S3: Measure the wind speed at the ventilation openings with an anemometer to determine whether the ventilation is smooth.

[0017] S4: Evaluate the possibility of natural ventilation, such as the number and positions of windows, skylights, ventilation shafts, etc.

[0018] S5: Building structure analysis. Check whether there are cracks and leakage problems in the walls, floors, ceilings, etc. of the underground garage, and evaluate their impact on the dehumidification effect.

[0019] S6: Analyze the hygroscopicity and air permeability of building materials to determine whether additional moisture-proof treatment is required.

[0020] When the difference between the hygroscopicity and air permeability of the building materials is large, additional moisture-proofing is required. When the hygroscopicity and air permeability of the building materials are good, additional moisture-proofing can be omitted.

[0021] S7: Underground water level monitoring. Set up underground water level monitoring points around or at the bottom of the underground garage, and regularly measure the underground water level.

[0022] Evaluate the impact of the underground water level on the humidity of the garage, especially the changes during and after the rainy season.

[0023] Furthermore, the specific process of evaluating the effectiveness of the ventilation system is as follows: Extract the number of ventilation openings, exhaust openings, inlet positions and sizes of the obtained underground garage.

[0024] Import them into the preset model library, and retrieve the information of the standard underground garage closest to the current underground garage from the preset model library.

[0025] The standard underground garage information includes the standard number of ventilation openings, standard number of exhaust openings, standard inlet position and standard inlet size.

[0026] Analyze the same items of the number of ventilation openings, exhaust openings, inlet positions and sizes of the underground garage and the standard number of ventilation openings, standard number of exhaust openings, standard inlet position and standard inlet size in the standard underground garage information.

[0027] Calculate the difference between the number of ventilation openings of the underground garage and the standard number of ventilation openings to obtain the first difference.

[0028] Calculate the difference between the number of exhaust vents in the underground garage and the standard number of exhaust vents to obtain the second difference;

[0029] Calculate the position deviation between the air inlet position and the standard air inlet position to obtain the third difference;

[0030] Calculate the difference between the air inlet size and the standard air inlet size to obtain the fourth difference;

[0031] When any three or more of the first difference being greater than the preset value, the second difference being greater than the preset value, the third difference being less than the preset value, and the fourth difference being less than the preset value occur simultaneously, it means that the effectiveness of the ventilation system is excellent;

[0032] When less than three of the first difference being greater than the preset value, the second difference being greater than the preset value, the third difference being less than the preset value, and the fourth difference being less than the preset value occur, it means that the effectiveness of the ventilation system is poor.

[0033] Furthermore, the determination process of whether the ventilation is smooth is as follows: At least three anemometers are set at different positions inside the ventilation opening. One anemometer is set at a distance of a1 from the ventilation opening, one anemometer is set at a distance of a2 from the ventilation opening, and another anemometer is set at a distance of a3 from the ventilation opening;

[0034] a1 distance > a2 distance > a3 distance;

[0035] After each anemometer at each position collects at least x times of wind speed information, calculate the average value of the x times of wind speed information at each position to obtain the evaluation value of a single anemometer;

[0036] When any one of the evaluation values of the three anemometers is less than the preset value, it means that the ventilation is not smooth;

[0037] When the evaluation values of the three anemometers are all greater than or equal to the preset value, it means that the ventilation is smooth.

[0038] Furthermore, the specific process of equipment selection is as follows: Collect the area, humidity, and ventilation conditions of the underground garage. According to the area, humidity, and ventilation conditions of the underground garage, select the corresponding number of dehumidifiers, and the dehumidifiers need to have an automatic adjustment function;

[0039] Collect the equipment room in the underground garage and areas with an area less than the preset value, and place desiccants in the equipment room in the underground garage and areas with an area less than the preset value;

[0040] Set air curtain machines at the entrance and exit of the underground garage;

[0041] At the same time, select the corresponding number of mobile dehumidifiers according to actual needs.

[0042] Furthermore, the specific process of performing temperature and humidity monitoring and analyzing the monitoring data is as follows:

[0043] SS1: Set up temperature and humidity monitoring points:

[0044] Location selection for basement monitoring points: Select different areas of the basement to set up monitoring points, including the entrance, the depths, the corners, and the areas where important equipment or items are stored;

[0045] Quantity and distribution: Determine the quantity and distribution of the monitoring points according to the size and layout of the basement;

[0046] Monitoring equipment: Select temperature and humidity sensors and equip them with data recording functions to record data in real time;

[0047] SS2: Location selection for outdoor monitoring points. Select representative outdoor areas to set up monitoring points, including open spaces and the perimeters of buildings;

[0048] SS3: Real-time data collection and recording. The monitoring equipment can record temperature and humidity data in real time and automatically upload it to the data management system;

[0049] Data analysis - Trend analysis: Analyze the change trends of temperature and humidity by comparing historical data and real-time monitoring data;

[0050] SS4: Abnormality detection. Set temperature and humidity thresholds. When the data exceeds the thresholds, an alarm is automatically triggered, and relevant personnel are notified for handling or the relevant dehumidification equipment is controlled to operate for dehumidification.

[0051] Furthermore, when abnormalities are found in the analysis of the monitoring data, the specific process of performing dehumidification prompts and dehumidification control is as follows:

[0052] Collect the humidity information outside the underground garage and the humidity information inside the underground garage;

[0053] When the humidity information outside the underground garage is greater than the humidity information inside the underground garage, generate control information to control the operation of the air curtains installed at the entrance and exit of the underground garage;

[0054] When the humidity information inside the underground garage is greater than the preset value and the humidity information outside the underground garage is also greater than the preset value, generate control information to control the operation of the dehumidification equipment in the underground garage for dehumidification operations;

[0055] When the humidity information outside the underground garage is less than the preset value and the humidity information inside the underground garage is greater than the preset value, generate control information to control the blower and the thin film air duct of the ventilation equipment in the underground garage for ventilation dehumidification.

[0056] Furthermore, for regular maintenance and management, monitor the status of the underground garage. The specific process of performing maintenance and management is as follows:

[0057] S(1): Equipment maintenance, including the maintenance of dehumidification equipment and ventilation equipment;

[0058] Clean the dehumidifier regularly, check whether the refrigerant of the dehumidifier is sufficient, check the electrical system of the dehumidifier, and lubricate and maintain key components such as the compressor and fan of the dehumidifier regularly;

[0059] Clean and check the ventilation equipment regularly, check the tightness of the ventilation ducts, and conduct regular inspections on the electrical system of the ventilation equipment;

[0060] S(2): Drainage system maintenance, including the maintenance of drainage pipes in the underground garage, drainage pump maintenance and sump maintenance:

[0061] Check regularly whether the drainage pipes are unobstructed and whether the joints of the drainage pipes are firm;

[0062] Check and maintain the drainage pump regularly, and check the power cord and control system of the drainage pump;

[0063] Check the water level of the sump regularly to ensure that the water level does not exceed the warning line, and clean the sundries and silt in the sump;

[0064] S(3): Waterproof layer inspection, check the integrity of the waterproof layer, regularly check whether the waterproof layer of the underground garage is intact, and check whether the joints of the waterproof layer are firm; check the aging condition of the waterproof layer material;

[0065] S(4): Dehumidification effect evaluation, regularly monitor the temperature and humidity of the basement, record the data and analyze the change trend, and evaluate the dehumidification effect according to the monitoring data;

[0066] Conduct on-site inspections of the basement regularly to observe whether there are damp and mildew phenomena;

[0067] Check the operating status of the dehumidification equipment and ventilation equipment to ensure their normal operation;

[0068] According to the evaluation results and on-site inspection conditions, adjust the dehumidification control strategy, including increasing the number of dehumidifiers and adjusting the ventilation frequency;

[0069] Optimize the dehumidification control strategy regularly to ensure its adaptation to the actual needs of the basement.

[0070] The present invention has the following advantages compared with the prior art: This energy-saving dehumidification control method for underground garages can accurately understand the humidity conditions, ventilation efficiency and potential problems of the underground garage through comprehensive environmental assessments, including temperature and humidity monitoring, ventilation condition assessment, natural ventilation possibility assessment, building structure analysis and underground water level monitoring, providing a scientific basis for subsequent equipment selection and dehumidification control strategies.

[0071] Establish a perfect temperature and humidity monitoring system, which can record and analyze the temperature and humidity data of the underground garage in real time, detect abnormalities in time and take corresponding dehumidification measures to effectively prevent problems such as dampness and mildew.

[0072] Automatically trigger an alarm according to the monitoring data and control the operation of relevant equipment to realize the intelligence and automation of dehumidification control, reduce manual intervention and improve work efficiency.

[0073] The intelligent linkage of ventilation equipment and dehumidification equipment can automatically adjust the working mode according to the internal and external humidity differences to achieve the best dehumidification effect.

[0074] According to the area, humidity and ventilation conditions of the underground garage, reasonably select equipment such as dehumidifiers, desiccants, air curtains, etc. While ensuring the dehumidification effect, the economy and practicability of the equipment are also considered.

[0075] Regular maintenance and management can ensure the normal operation of dehumidification equipment and ventilation equipment, extend the service life of the equipment and reduce the maintenance cost.

[0076] Regular evaluation of the drainage system, waterproof layer and dehumidification effect can detect and solve problems in time to ensure the stability and comfort of the underground garage environment.

[0077] Flexibly adjust the dehumidification control strategy according to the monitoring data and on-site inspection conditions, including increasing the number of dehumidifiers, adjusting the ventilation frequency, etc. to adapt to the changes in the actual environment of the underground garage.

[0078] Through intelligent dehumidification control and regular equipment maintenance, the operation efficiency of the equipment can be optimized, unnecessary energy consumption can be reduced, and the goal of energy conservation and emission reduction can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] Figure 1 is the overall flowchart of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0080] The following details the embodiments of the present invention. The embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present invention is not limited to the following embodiments.

[0081] As Figure 1 shown, this embodiment provides a technical solution: an energy-saving dehumidification control method for an underground garage, including the following steps:

[0082] Step 1: First, conduct a preliminary evaluation, including environmental evaluation and equipment selection;

[0083] Step 2: Establish a monitoring system, conduct temperature and humidity monitoring and analyze the monitoring data;

[0084] Step 3: When anomalies are found in the monitoring data analysis, perform dehumidification prompts and dehumidification control;

[0085] Step 4: Conduct regular maintenance and management, monitor the status of the underground garage, and perform maintenance and management.

[0086] Furthermore, the environmental assessment process in Step 1 is as follows:

[0087] S1: Conduct temperature and humidity monitoring. Use temperature and humidity monitoring instruments to set monitoring points at different locations in the underground garage (such as the entrance, exit, central area, corners, etc.);

[0088] Continuously record the temperature and humidity data within a preset duration (such as one week or one month), and analyze the temperature and humidity data to obtain the temperature and humidity change trends and distribution characteristics of the underground garage.

[0089] S2: Evaluate the ventilation conditions. Collect the number of ventilation openings, exhaust openings, the location and size of the air inlet in the underground garage, and evaluate the effectiveness of the ventilation system;

[0090] S3: Measure the wind speed at the ventilation opening with an anemometer to determine whether the ventilation is smooth;

[0091] S4: Evaluate the possibility of natural ventilation, such as the number and location of windows, skylights, ventilation shafts, etc.;

[0092] S5: Conduct building structure analysis. Check whether there are cracks and leakage problems in the walls, floors, ceilings, etc. of the underground garage, and evaluate their impact on the dehumidification effect;

[0093] S6: Analyze the hygroscopicity and air permeability of building materials to determine whether additional moisture-proof treatment is required;

[0094] When the difference between the hygroscopicity and air permeability of building materials is large, additional moisture-proofing is required. When the hygroscopicity and air permeability of building materials are good, additional moisture-proofing can be omitted;

[0095] S7: Monitor the groundwater level. Set groundwater level monitoring points around or at the bottom of the underground garage and regularly measure the groundwater level;

[0096] Evaluate the impact of the groundwater level on the garage humidity, especially the changes during and after the rainy season;

[0097] In the above process, by setting temperature and humidity monitoring points at different locations in the underground garage and continuously recording the data, accurate temperature and humidity change trends and distribution characteristics can be obtained. These data provide a scientific basis for subsequent dehumidification control strategies and equipment selection, making the decision-making more accurate and effective.

[0098] Evaluating ventilation conditions, including the number of ventilation openings, exhaust openings, the location and size of intake openings, etc., helps to identify bottlenecks and potential problems in the ventilation system. By measuring the wind speed at the ventilation openings with an anemometer, it is possible to intuitively judge whether the ventilation is smooth, providing a basis for optimizing the ventilation design and improving ventilation efficiency.

[0099] Evaluating the possibility of natural ventilation, such as the number and location of windows, skylights, ventilation shafts, etc., helps to make full use of natural resources and reduce energy consumption. By reasonably designing the natural ventilation system, it can, to a certain extent, replace mechanical ventilation and reduce operating costs.

[0100] Building structure analysis can promptly detect cracks and leaks in parts such as walls, floors, and ceilings, which are often the main causes of increased humidity. By repairing these problems, the waterproof performance of the underground garage can be improved and the dehumidification burden can be reduced.

[0101] Analyzing the hygroscopicity and air permeability of building materials helps to determine whether additional moisture-proof treatment is needed. For building materials with poor hygroscopicity and air permeability, taking appropriate moisture-proof measures can significantly improve the dehumidification effect and extend the service life of the materials.

[0102] Monitoring the groundwater level, especially its changes during and after the rainy season, helps to evaluate the impact of the groundwater level on the humidity in the garage. By reasonably controlling the groundwater level, the contribution of groundwater to the humidity in the garage can be reduced and the dehumidification difficulty can be lowered.

[0103] The specific process of evaluating the effectiveness of the ventilation system is as follows: Extract the number of ventilation openings, exhaust openings, the location and size of intake openings of the obtained underground garage;

[0104] Import them into the preset model library and retrieve the information of the standard underground garage closest to the current underground garage from the preset model library;

[0105] The standard underground garage information includes the standard number of ventilation openings, standard number of exhaust openings, standard intake opening location, and standard intake opening size;

[0106] Analyze the same items of the number of ventilation openings, exhaust openings, the location and size of intake openings of the underground garage and the standard number of ventilation openings, standard number of exhaust openings, standard intake opening location, and standard intake opening size in the standard underground garage information;

[0107] Calculate the difference between the number of ventilation openings in the underground garage and the standard number of ventilation openings to obtain the first difference;

[0108] Calculate the difference between the number of exhaust openings in the underground garage and the standard number of exhaust openings to obtain the second difference;

[0109] Calculate the position deviation between the intake opening location and the standard intake opening location to obtain the third difference;

[0110] Calculate the difference between the air inlet size and the standard air inlet size to obtain the fourth difference;

[0111] When any three or more of the first difference being greater than the preset value, the second difference being greater than the preset value, the third difference being less than the preset value, and the fourth difference being less than the preset value occur simultaneously, that is, the effectiveness of the ventilation system is excellent;

[0112] When less than three of the first difference being greater than the preset value, the second difference being greater than the preset value, the third difference being less than the preset value, and the fourth difference being less than the preset value occur, that is, the effectiveness of the ventilation system is poor;

[0113] The above process provides a reference benchmark for the ventilation system of the current underground garage through the standard underground garage information in the preset model library. This standardized evaluation method ensures the consistency and fairness of the evaluation, enabling the ventilation systems of different underground garages to be compared based on the same standard.

[0114] By calculating the first difference, the second difference, the third difference, and the fourth difference, the parameters of the ventilation system are quantitatively compared with the standard values. This method of quantitative analysis makes the evaluation results more intuitive and accurate, helping to discover the problems existing in the ventilation system and the direction of optimization.

[0115] The evaluation process covers multiple dimensions such as the number of ventilation openings, the number of exhaust openings, the position and size of the air inlets, etc., comprehensively considering all aspects of the ventilation system. This multi-dimensional evaluation method can more comprehensively reflect the overall performance of the ventilation system and avoid the one-sidedness that may be caused by single-dimensional evaluation.

[0116] Flexibly judge the effectiveness of the ventilation system according to the comparison results of the first difference, the second difference, the third difference, and the fourth difference with the preset value. This judgment method takes into account both the actual performance of the ventilation system and the differences between different underground garages, making the evaluation results more in line with the actual situation.

[0117] Through the evaluation results, the problems existing in the ventilation system and the direction of optimization can be identified. For example, if the first difference or the second difference is large, it indicates that the number of ventilation openings or exhaust openings is insufficient and needs to be increased; if the third difference or the fourth difference is large, it indicates that the position or size of the air inlet needs to be adjusted. These specific guiding suggestions help to formulate targeted optimization measures to improve the effectiveness of the ventilation system.

[0118] Improve operational efficiency: An effective ventilation system can reduce the humidity and temperature in the underground garage, improve the air quality, thus creating a more comfortable environment. At the same time, the optimized ventilation system can also reduce energy consumption and operating costs, improving the operational efficiency of the underground garage.

[0119] The specific process of evaluating the effectiveness of the ventilation system provides a scientific and objective method for evaluating the ventilation system in the underground garage through the benefits of standardized evaluation, quantitative analysis, multi-dimensional evaluation, flexible judgment, and guidance for optimization, which helps to improve the effectiveness of the ventilation system and the operation efficiency of the underground garage.

[0120] The determination process of whether the ventilation is smooth is as follows: At least three anemometers are set at different positions inside the ventilation opening. One anemometer is set at a distance of a1 from the ventilation opening, one anemometer is set at a distance of a2 from the ventilation opening, and another anemometer is set at a distance of a3 from the ventilation opening;

[0121] The distance a1 > the distance a2 > the distance a3;

[0122] After each anemometer at each position collects at least x times of wind speed information, the mean value of the x times of wind speed information at each position is calculated to obtain the evaluation value of a single anemometer, where x ≥ 10;

[0123] When any one of the evaluation values of the three anemometers is less than the preset value, it indicates that the ventilation is not smooth;

[0124] When the evaluation values of the three anemometers are all greater than or equal to the preset value, it indicates that the ventilation is smooth;

[0125] Setting at least three anemometers at different positions inside the ventilation opening in the above process can capture the subtle changes in the wind speed inside the ventilation opening. Since there may be problems of uneven air flow distribution inside the ventilation opening, multi-point monitoring can more comprehensively reflect the overall wind speed situation of the ventilation opening, thereby improving the accuracy of the evaluation.

[0126] Setting the distance gradient to reflect the air flow change: By setting anemometers at different distances, the change process of the air flow from the outlet of the ventilation opening to the distance can be captured. This setting of the distance gradient helps to analyze the diffusion and attenuation of the air flow near the ventilation opening and provides a basis for optimizing the ventilation design.

[0127] After each anemometer at each position collects at least x times of wind speed information and calculates the mean value, this method of multiple collections can reduce the random error of single measurement and improve the stability and reliability of the evaluation value.

[0128] Judgment by the preset value to simplify the operation: By setting a preset value as the judgment standard for whether the ventilation is smooth, the evaluation process is simplified. When the evaluation values of the three anemometers are all greater than or equal to the preset value, it can be determined that the ventilation is smooth; when any one is less than the preset value, it can be determined that the ventilation is not smooth. This intuitive judgment method is convenient for quickly drawing conclusions and improving work efficiency.

[0129] The determination result can provide guidance for the optimization of the ventilation system. If the ventilation is not smooth, the monitoring data of the anemometer can be used to identify problems, such as unreasonable ventilation outlet design, air flow obstruction, etc., and corresponding optimization measures can be taken. By optimizing the ventilation system, the ventilation efficiency can be improved and the environmental quality of the underground garage can be enhanced.

[0130] The above determination process of whether the ventilation is smooth provides a scientific and accurate method for evaluating the performance of the ventilation system through benefits such as multi-point monitoring, distance gradient setting, multiple acquisitions, preset value determination, and guidance for optimization, which helps to improve the ventilation efficiency and the environmental quality of the underground garage.

[0131] The specific process of equipment selection is as follows: Collect the area, humidity, and ventilation conditions of the underground garage. According to the area, humidity, and ventilation conditions of the underground garage, select the corresponding number of dehumidifiers, and the dehumidifiers need to have an automatic adjustment function.

[0132] Collect the equipment rooms in the underground garage and areas with an area less than the preset value, and place desiccants in the equipment rooms in the underground garage and areas with an area less than the preset value.

[0133] Install air curtain machines at the entrance and exit of the underground garage.

[0134] At the same time, select the corresponding number of mobile dehumidifiers according to actual needs.

[0135] The benefits of dehumidifier selection include:

[0136] Precise selection according to area, humidity, and ventilation conditions: By collecting the area, humidity, and ventilation conditions of the underground garage, the corresponding number of dehumidifiers can be selected more precisely. This ensures that the dehumidification capacity of the dehumidifier can match the actual situation of the garage, avoiding problems such as insufficient dehumidification or over-dehumidification.

[0137] Automatic adjustment function improves energy efficiency: Selecting dehumidifiers with an automatic adjustment function can automatically adjust the working state according to the humidity change in the garage, avoiding waste of energy. This helps to improve the energy efficiency of the dehumidifier and reduce the operating cost.

[0138] Guarantee the garage environment: The use of dehumidifiers can effectively reduce the humidity in the garage, prevent moisture and mildew from occurring on the walls, floors, and vehicles. At the same time, it can also reduce water vapor condensation, prevent the ground from icing and vehicles from skidding, and provide a dry and comfortable parking environment for car owners.

[0139] The benefits of desiccant placement include:

[0140] For small areas and special regions: Desiccants are placed in equipment rooms of underground garages and areas with an area smaller than a preset value, enabling moisture-proof treatment for these special regions. These regions are prone to moisture due to their small area or poor ventilation, and the use of desiccants can effectively alleviate this problem.

[0141] Cost-effective: Desiccants are relatively inexpensive, have a long service life, can continuously maintain the humidity level inside the garage, and achieve a good moisture-proof effect. This is a cost-effective option for garages that require long-term moisture-proof protection.

[0142] The benefits of installing air curtains include:

[0143] Blocking the intrusion of moisture: Installing air curtains at the entrances and exits of underground garages can form an air barrier to block the air exchange between the inside and outside of the garage. This helps reduce the intrusion of moisture from outside the garage and maintain a dry environment inside the garage.

[0144] Improving air quality: Air curtains can also effectively reduce noise, dust, and odors inside and outside the garage, thereby improving the air quality inside the garage. This is of great significance for enhancing the parking experience of car owners.

[0145] The benefits of choosing mobile dehumidifiers, flexibly coping with moisture problems: Selecting the corresponding number of mobile dehumidifiers according to actual needs can flexibly cope with moisture problems in different areas of the garage. Mobile dehumidifiers are portable and can be easily moved to the areas that need dehumidification for work.

[0146] Reducing the initial investment cost: Compared with fixed dehumidifiers, the initial investment cost of mobile dehumidifiers is lower. Car owners can flexibly choose the number and model of mobile dehumidifiers according to the actual situation and budget of the garage.

[0147] In summary, the specific process of equipment selection comprehensively considers various factors of the underground garage and selects corresponding equipment accordingly. The benefits of this process are mainly reflected in improving dehumidification efficiency, reducing operating costs, ensuring the garage environment, being cost-effective, blocking the intrusion of moisture, improving air quality, and flexibly coping with moisture problems. These benefits together provide a dry, comfortable, and safe parking environment for car owners.

[0148] The specific process of performing temperature and humidity monitoring and analyzing the monitoring data is as follows:

[0149] SS1: Setting up temperature and humidity monitoring points:

[0150] Selection of the setting positions of monitoring points in the basement: Select different areas of the basement to set up monitoring points, including the entrance, the depth, the corners, and the areas where important equipment or items are stored;

[0151] Quantity and distribution: Determine the quantity and distribution of monitoring points based on the size and layout of the basement garage;

[0152] Monitoring equipment: Select temperature and humidity sensors and equip them with data recording functions to record data in real time;

[0153] SS2: Selection of outdoor monitoring point settings. Select representative outdoor areas to set up monitoring points, including open spaces and around buildings;

[0154] SS3: Real-time recording of data collection. The monitoring equipment can record temperature and humidity data in real time and automatically upload it to the data management system;

[0155] Data analysis - Trend analysis: Analyze the change trends of temperature and humidity by comparing historical data and real-time monitoring data;

[0156] SS4: Abnormality detection. Set temperature and humidity thresholds. When the data exceeds the threshold, an alarm is automatically triggered, and relevant personnel are notified for handling or the relevant dehumidification equipment is controlled to operate for dehumidification;

[0157] The rationality of the temperature and humidity monitoring point settings includes: Comprehensive coverage: Set up monitoring points in different areas of the basement garage, including the entrance, deep inside, corners, and areas where important equipment or items are stored, which can comprehensively reflect the temperature and humidity conditions in the basement garage and ensure the accuracy and representativeness of the monitoring data.

[0158] Strong pertinence: The selection of outdoor monitoring points also considers representative areas, such as open spaces and around buildings, which helps to analyze the impact of the outdoor environment on the temperature and humidity of the underground garage and provides a basis for further optimizing the garage environment.

[0159] Reasonable quantity and distribution: Determine the quantity and distribution of monitoring points based on the size and layout of the basement garage, which not only ensures the comprehensiveness of monitoring but also avoids waste of resources.

[0160] Convenience of data collection and real-time recording

[0161] High degree of automation: The monitoring equipment can record temperature and humidity data in real time and automatically upload it to the data management system, reducing manual intervention and improving work efficiency.

[0162] High data accuracy: Real-time monitoring data can accurately reflect the temperature and humidity conditions of the basement garage and the outdoor environment, providing a reliable basis for subsequent data analysis.

[0163] The depth of data analysis and trend analysis includes:

[0164] Comparison of historical data and real-time monitoring data: By comparing historical data and real-time monitoring data, the changing trends of temperature and humidity can be analyzed, which helps to discover potential environmental problems and provides a basis for formulating countermeasures.

[0165] Abnormal detection and alarm: Set temperature and humidity thresholds. When the data exceeds the thresholds, an alarm is automatically triggered, and relevant personnel are notified to handle it or control the operation of relevant dehumidification equipment for dehumidification. This abnormal detection mechanism can respond to environmental changes in a timely manner, ensuring the stability and safety of the garage environment.

[0166] Optimizing decision-making and resource utilization efficiency includes:

[0167] Optimizing decision-making support: Monitoring data and analysis results can provide a scientific basis for optimizing the garage environment, adjusting the operation strategy of dehumidification equipment, etc., which helps to improve resource utilization efficiency and management level.

[0168] Energy conservation and emission reduction: Through real-time monitoring and data analysis, abnormal temperature and humidity problems can be discovered and solved in a timely manner, avoiding unnecessary energy waste and environmental pollution, and achieving the goal of energy conservation and emission reduction.

[0169] In summary, the specific process of monitoring temperature and humidity and analyzing the monitoring data provides a scientific and efficient method for the temperature and humidity management of underground garages and outdoor environments through measures such as reasonably setting monitoring points, collecting data in real time, deeply analyzing trends, and abnormal detection. This process not only improves the stability and safety of the garage environment but also provides strong support for optimizing decision-making and resource utilization.

[0170] When abnormalities are found through the analysis of the monitoring data, the specific process of dehumidification prompt and dehumidification control is as follows:

[0171] Collect the humidity information outside the underground garage and the humidity information inside the underground garage;

[0172] When the humidity information outside the underground garage is greater than the humidity information inside the underground garage, control information is generated to control the operation of the air curtains set at the entrance and exit of the underground garage;

[0173] When the humidity information inside the underground garage is greater than the preset value and the humidity information outside the underground garage is also greater than the preset value, control information is generated to control the operation of the dehumidification equipment in the underground garage for dehumidification operations;

[0174] When the humidity information outside the underground garage is less than the preset value and the humidity information inside the underground garage is greater than the preset value, control information is generated to control the blower and the film air duct of the ventilation equipment in the underground garage for ventilation dehumidification;

[0175] The above process realizes intelligent response, timely dehumidification, and precise control of the air curtain machine. When it is detected that the humidity outside the underground garage is greater than that inside, the intelligent control system will immediately generate control information to start the air curtain machines at the entrance and exit of the underground garage. The air curtain machine can form an air barrier to effectively block the entry of high-humidity external air into the garage, thus maintaining the stability of the humidity inside the garage.

[0176] When it is detected that the humidity inside and outside the underground garage both exceed the preset value, the control system will immediately generate control information to start the dehumidification equipment for dehumidification operations. This intelligent response mechanism can quickly reduce the humidity inside the garage and prevent various problems caused by excessive humidity, such as mold growth and equipment moisture.

[0177] It also realizes high efficiency and energy conservation, optimizes resource utilization, and intelligently selects ventilation and dehumidification. When it is detected that the humidity outside the underground garage is less than the preset value while the humidity inside is greater than the preset value, the control system will choose to start the blower and thin film air duct of the ventilation equipment for ventilation and dehumidification. This strategy can use the external low-humidity air to reduce the humidity inside the garage and avoid the unnecessary operation of the dehumidification equipment, thus achieving high efficiency and energy conservation.

[0178] Through the intelligent control system, the running time and intensity of the dehumidification equipment can be precisely controlled to avoid energy waste and equipment loss caused by excessive dehumidification. This helps to reduce the operating cost and improve the resource utilization efficiency.

[0179] Improve the garage environment, ensure safety, and improve the air quality of the garage: The ventilation and dehumidification process not only helps to reduce the humidity inside the garage but also improves the air quality and reduces the growth of harmful substances such as mold and bacteria. This helps to provide a healthier and more comfortable parking environment.

[0180] Ensure the safety of equipment and items: Important equipment and items such as vehicles and electrical equipment may be stored in the underground garage. Excessive humidity can damage these equipment and items. Through the intelligent dehumidification control system, abnormal humidity problems can be detected and processed in a timely manner, thus ensuring the safety of equipment and items.

[0181] When abnormalities are found through the analysis of the monitored data, the specific process of dehumidification prompt and dehumidification control, through measures such as intelligent response, high efficiency and energy conservation, and optimization of resource utilization, effectively improves the environmental quality of the underground garage, ensures the safety of equipment and items, and also improves the resource utilization efficiency.
