Description

Technical Field

[0001] The invention relates to the field of control methods, and in particular to an energy-saving underground garage dehumidification control method. Background Art

[0002] Dehumidification of underground garages refers to taking a series of measures to reduce and control the humidity level in the garage in the specific environment of the underground garage, so as to maintain the dryness, comfort and safety of the garage environment;

[0003] The main reasons for dampness in underground garages include groundwater infiltration, poor drainage systems, poor ventilation, and climate factors. These factors lead to increased humidity in the garage, which not only affects the maintenance of vehicles and equipment, but may also cause problems such as mold on the walls and rust on the metal.

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

[0005] The existing dehumidification control method has poor dehumidification effect and a single dehumidification mode, which has a certain impact on the use of the dehumidification control method. Therefore, an energy-saving underground garage dehumidification control method is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is: how to solve the problem that the existing dehumidification control method has poor dehumidification control effect and a single dehumidification method, which has brought certain impacts on the use of the dehumidification control method, and provides an energy-saving underground garage dehumidification control method.

[0007] The present invention solves the above technical problems through the following technical solutions, and the present invention comprises the following steps:

[0008] Step 1: Conduct preliminary assessment, environmental assessment and equipment selection;

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

[0010] Step 3: When abnormalities are found in the monitoring data analysis, dehumidification prompts and dehumidification control are carried out;

[0011] Step 4: Regular maintenance and management, monitor the status of the underground garage, and carry out maintenance and management.

[0012] Furthermore, the environmental assessment process of step one is as follows:

[0013] S1: Conduct temperature and humidity monitoring, use temperature and humidity monitoring instruments, and set up monitoring points at different locations in the underground garage (such as entrances, exits, central areas, corners, etc.);

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

[0015] S2: Ventilation condition assessment, collect the number of vents, exhaust vents, air inlet location and size of the underground garage, and evaluate the effectiveness of the ventilation system;

[0016] S3: Use an anemometer to measure the wind speed at the vent to determine whether the ventilation is smooth;

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

[0018] S4: 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] S5: Analyze the moisture absorption and air permeability of building materials to determine whether additional moisture-proofing treatment is required;

[0020] When the hygroscopicity and air permeability of building materials are poor, additional moisture-proofing is required. When the hygroscopicity and air permeability of building materials are good, additional moisture-proofing is not required.

[0021] S6: Groundwater level monitoring: set up groundwater level monitoring points around or at the bottom of the underground garage to measure the groundwater level regularly;

[0022] Assess the impact of groundwater levels on garage humidity, especially changes during and after the rainy season.

[0023] Furthermore, the specific process of evaluating the effectiveness of the ventilation system is as follows: extracting the number of vents, the number of exhaust vents, and the position and size of the air inlet of the underground garage;

[0024] Importing it into a preset model library, and retrieving standard underground garage information closest to the current underground garage from the preset model library;

[0025] Standard underground garage information includes the number of standard vents, the number of standard exhaust vents, the location of standard air inlets, and the size of standard air inlets;

[0026] Analyze the same items as the number of vents, number of exhaust vents, location and size of air inlets in the underground garage and the standard number of vents, number of exhaust vents, location and size of air inlets in the standard underground garage information;

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

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

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

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

[0031] When any three or more of the first difference being greater than a preset value, the second difference being greater than a preset value, the third difference being less than a preset value, and the fourth difference being less than a preset value appear at the same time, the effectiveness of the ventilation system is excellent;

[0032] When only three or less 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 appear, the effectiveness of the ventilation system is poor.

[0033] Furthermore, the process of determining whether the ventilation is smooth is as follows: at least three anemometers are arranged at different positions in the ventilation opening, wherein one anemometer is arranged at a distance a1 from the ventilation opening, one anemometer is arranged at a distance a2 from the ventilation opening, and another anemometer is arranged at a distance a3 from the ventilation opening;

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

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

[0036] When any of the three anemometer evaluation values ​​is less than the preset value, it means that the ventilation is poor;

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

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

[0039] Collect the equipment rooms in the underground garage and the areas with an area smaller than the preset value, and put desiccant in the equipment rooms in the underground garage and the areas with an area smaller than the preset value;

[0040] Install 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 monitoring temperature and humidity and analyzing the monitoring data is as follows:

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

[0044] Selection of location for monitoring points in basement: Select different areas of the basement to set monitoring points, including entrances, deep areas, corners, and areas where important equipment or items are stored;

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

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

[0047] SS2: Selection of outdoor monitoring point locations: Select representative outdoor areas to set up monitoring points, including open areas and around buildings;

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

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

[0050] SS4: Abnormal detection, set temperature and humidity thresholds. When the data exceeds the threshold, an alarm is automatically triggered and relevant personnel are notified to handle it or control the operation of relevant dehumidification equipment for dehumidification.

[0051] Furthermore, when the monitoring data analysis finds an abnormality, the specific process of performing dehumidification prompt and dehumidification control is as follows:

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

[0053] 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 air curtain machines 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, control information is generated to control the dehumidification equipment in the underground garage to operate the dehumidification operation;

[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, control information is generated to control the blower and the film duct of the ventilation equipment of the underground garage to ventilate and dehumidify.

[0056] Further, regular maintenance and management are carried out to monitor the status of the underground garage. The specific process of maintenance and management is as follows:

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

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

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

[0060] S(2): Drainage system maintenance, including drainage pipe maintenance, drainage pump maintenance and water collection well maintenance in underground garages:

[0061] Regularly check whether the drainage pipes are unobstructed and whether the interfaces of the drainage pipes are firm;

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

[0063] Check the water level in the water collection well regularly to ensure that it does not exceed the warning line and clean up the debris and silt in the water collection well;

[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 whether the joints of the waterproof layer are firm; check the aging 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 based on the monitoring data;

[0066] Regularly conduct on-site inspections of the basement to observe whether there is moisture and mildew;

[0067] Check the operating status of dehumidification equipment and ventilation equipment to ensure they are working properly;

[0069] Regularly review and optimize the dehumidification control strategy to ensure it meets the actual needs of the basement.

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

[0071] Establish a complete temperature and humidity monitoring system that 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 moisture and mildew.

[0072] Automatically trigger alarms and control the operation of related equipment based on monitoring data, realize intelligent and automated dehumidification control, reduce manual intervention and improve work efficiency.

[0073] The intelligent linkage between ventilation equipment and dehumidification equipment can automatically adjust the working mode according to the difference in humidity inside and outside to achieve the best dehumidification effect.

[0074] According to the area, humidity and ventilation conditions of the underground garage, dehumidifiers, desiccants, air curtains and other equipment are reasonably selected to ensure the dehumidification effect while also taking into account the economy and practicality of the equipment.

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

[0076] Regular evaluation of the drainage system, waterproof layer and dehumidification effect can promptly detect and solve problems and ensure a stable and comfortable underground garage environment.

[0077] According to monitoring data and on-site inspections, the dehumidification control strategy is flexibly adjusted, including increasing the number of dehumidifiers, adjusting ventilation frequency, etc., to adapt to changes in the actual environment of the underground garage.

[0078] Through intelligent dehumidification control and regular equipment maintenance, the operating 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 It is the overall flow chart of the present invention. DETAILED DESCRIPTION

[0080] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

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

[0082] Step 1: Conduct preliminary assessment, environmental assessment and equipment selection;

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

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

[0085] Step 4: Regular maintenance and management, monitor the status of the underground garage, and carry out maintenance and management.

[0086] Furthermore, the environmental assessment process of step one is as follows:

[0087] S1: Conduct temperature and humidity monitoring, use temperature and humidity monitoring instruments, and set up monitoring points at different locations in the underground garage (such as entrances, exits, central areas, corners, etc.);

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

[0089] S2: Ventilation condition assessment, collect the number of vents, exhaust vents, air inlet location and size of the underground garage, and evaluate the effectiveness of the ventilation system;

[0090] S3: Use an anemometer to measure the wind speed at the vent to determine whether the ventilation is smooth;

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

[0092] S4: 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] S5: Analyze the moisture absorption and air permeability of building materials to determine whether additional moisture-proofing treatment is required;

[0094] When the hygroscopicity and air permeability of building materials are poor, additional moisture-proofing is required. When the hygroscopicity and air permeability of building materials are good, additional moisture-proofing is not required.

[0095] S6: Groundwater level monitoring: set up groundwater level monitoring points around or at the bottom of the underground garage to measure the groundwater level regularly;

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

[0097] In the above process, by setting up temperature and humidity monitoring points at different locations in the underground garage and continuously recording 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 decision-making more accurate and effective.

[0098] Evaluating ventilation conditions, including the number of vents, the number of exhaust vents, the location and size of air inlets, etc., helps identify bottlenecks and potential problems in the ventilation system. Measuring the wind speed at the vents with an anemometer can intuitively determine whether the ventilation is smooth, providing a basis for optimizing 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., can help make full use of natural resources and reduce energy consumption. By properly designing the natural ventilation system, it can replace mechanical ventilation to a certain extent and reduce operating costs.

[0100] Building structural analysis can promptly detect cracks and leaks in walls, floors, ceilings, etc., which are often the main cause 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 moisture absorption and air permeability of building materials can help determine whether additional moisture-proofing treatment is needed. For building materials with poor moisture absorption and air permeability, taking appropriate moisture-proofing measures can significantly improve the dehumidification effect and extend the service life of the materials.

[0102] Monitoring the groundwater level, especially the changes during and after the rainy season, can help assess the impact of the groundwater level on garage humidity. By properly controlling the groundwater level, the contribution of groundwater to garage humidity can be reduced, making dehumidification easier.

[0103] The specific process of evaluating the effectiveness of the ventilation system is as follows: extracting the number of vents, the number of exhaust vents, and the position and size of the air inlet of the underground garage;

[0104] Importing it into a preset model library, and retrieving standard underground garage information closest to the current underground garage from the preset model library;

[0105] Standard underground garage information includes the number of standard vents, the number of standard exhaust vents, the location of standard air inlets, and the size of standard air inlets;

[0106] Analyze the same items as the number of vents, number of exhaust vents, location and size of air inlets in the underground garage and the standard number of vents, number of exhaust vents, location and size of air inlets in the standard underground garage information;

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

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

[0109] Calculate the position deviation between the air inlet position and the standard air inlet position to obtain a third difference value;

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

[0111] When any three or more of the first difference being greater than a preset value, the second difference being greater than a preset value, the third difference being less than a preset value, and the fourth difference being less than a preset value appear at the same time, the effectiveness of the ventilation system is excellent;

[0112] When only three or less of the first difference is greater than the preset value, the second difference is greater than the preset value, the third difference is less than the preset value, and the fourth difference is less than the preset value appear, 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 by presetting the standard underground garage information in the model library. This standardized evaluation method ensures the consistency and fairness of the evaluation, so that the ventilation systems of different underground garages can be compared based on the same standards.

[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 quantitative analysis method makes the evaluation results more intuitive and accurate, and helps to find problems in the ventilation system and the direction of optimization.

[0115] The evaluation process covers multiple dimensions, including the number of vents, the number of exhaust vents, the location and size of the air inlets, etc., taking into account 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 a single-dimensional evaluation.

[0116] According to the comparison results of the first difference, the second difference, the third difference and the fourth difference with the preset value, the effectiveness of the ventilation system is flexibly judged. This judgment method takes into account both the actual performance of the ventilation system and the differences between different underground garages, so that the evaluation result is more in line with the actual situation.

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

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

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

[0120] The process of determining whether the ventilation is smooth is as follows: at least three anemometers are arranged at different positions in the ventilation opening, wherein one anemometer is arranged at a distance a1 from the ventilation opening, one anemometer is arranged at a distance a2 from the ventilation opening, and another anemometer is arranged at a distance a3 from the ventilation opening;

[0121] a3 distance>a2 distance>a3 distance;

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

[0123] When any of the three anemometer evaluation values ​​is less than the preset value, it means that the ventilation is poor;

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

[0125] In the above process, at least three anemometers are set at different locations in the vent to capture the slight changes in wind speed inside the vent. Since there may be uneven airflow distribution inside the vent, multi-point monitoring can more comprehensively reflect the overall wind speed of the vent, thereby improving the accuracy of the assessment.

[0126] Distance gradient setting reflects airflow changes: By setting anemometers at different distances (a1, a2, a3, and a3 distance>a2 distance>a1 distance, note that the original description of a3 distance>a2 distance>a3 distance should be a typo, it should be a3 distance>a2 distance>a1 distance), the change process of airflow from the vent outlet to the distance can be captured. This distance gradient setting helps to analyze the diffusion and attenuation of airflow near the vent, and provides a basis for optimizing ventilation design.

[0127] The anemometer at each location collects wind speed information at least x times and then calculates the average value. This multiple collection method can reduce the random error of a single measurement and improve the stability and reliability of the evaluation value.

[0128] Preset value judgment, simplified operation: By setting a preset value as the judgment standard for whether the ventilation is smooth or not, the evaluation process is simplified. When the evaluation values ​​of the three anemometers are greater than or equal to the preset value, it can be judged that the ventilation is smooth; when any one is less than the preset value, it can be judged that the ventilation is not smooth. This intuitive judgment method makes it easy to draw conclusions quickly and improves work efficiency.

[0129] The judgment results can provide guidance for the optimization of the ventilation system. If the ventilation is not smooth, the problem can be found out based on the monitoring data of the anemometer, such as unreasonable vent design, air flow obstruction, etc., so as to take corresponding optimization measures. By optimizing the ventilation system, the ventilation efficiency can be improved and the environmental quality of the underground garage can be improved.

[0130] The above-mentioned process of determining whether ventilation is smooth or not provides a scientific and accurate method for evaluating the performance of the ventilation system through the benefits of multi-point monitoring, distance gradient setting, multiple collections, preset value determination, and guided optimization, which helps to improve ventilation efficiency and the environmental quality of underground garages.

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

[0132] Collect the equipment rooms in the underground garage and the areas with an area smaller than the preset value, and put desiccant in the equipment rooms in the underground garage and the areas with an area smaller 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 choosing a dehumidifier

[0136] Accurate selection based on 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 accurately. This ensures that the dehumidification capacity of the dehumidifier can match the actual situation of the garage, avoiding the problem of insufficient or excessive dehumidification.

[0137] Automatic adjustment function improves energy efficiency: Choose a dehumidifier with automatic adjustment function, which can automatically adjust the working state according to the humidity changes in the garage to avoid energy waste. This helps to improve the energy efficiency of the dehumidifier and reduce operating costs.

[0138] Protect the garage environment: The use of a dehumidifier can effectively reduce the humidity in the garage, prevent moisture and mold from forming on the walls, floors and vehicles. At the same time, it can also reduce condensation, prevent the ground from icing and the vehicle from slipping, and provide a dry and comfortable parking environment for car owners.

[0139] The benefits of desiccant placement

[0140] For small areas and special areas: Desiccant can be placed in the equipment room of the underground garage and in areas with an area smaller than the preset value to prevent moisture in these special areas. These areas are often susceptible to moisture due to their small size or poor ventilation, and the use of desiccant can effectively alleviate this problem.

[0141] Economical: Desiccant is relatively cheap, has a long service life, and can continuously maintain the humidity level inside the garage, achieving a good moisture-proof effect. This is an economical choice for garages that require long-term moisture-proof protection.

[0142] Benefits of air curtain machine setting

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

[0144] Improve air quality: The air curtain machine can also effectively reduce noise, dust and odor inside and outside the garage, thereby improving the air quality inside the garage. This is of great significance to improving the parking experience of car owners.

[0145] The benefits of choosing a mobile dehumidifier

[0146] Flexible response to moisture problems: Selecting the corresponding number of mobile dehumidifiers according to actual needs can flexibly deal with moisture problems in different areas of the garage. Mobile dehumidifiers are portable and can be easily moved to the area that needs dehumidification to work.

[0147] Lower initial investment cost: Compared with fixed dehumidifiers, mobile dehumidifiers have lower initial investment costs. Car owners can flexibly choose the number and model of mobile dehumidifiers according to the actual situation and budget of the garage.

[0148] In summary, the specific process of equipment selection takes into account various factors of underground garages and selects corresponding equipment in a targeted manner. The benefits of this process are mainly reflected in improving dehumidification efficiency, reducing operating costs, protecting the garage environment, being economical, blocking moisture intrusion, improving air quality, and flexibly coping with moisture problems. These benefits together provide car owners with a dry, comfortable and safe parking environment.

[0149] The specific process of monitoring temperature and humidity and analyzing the monitoring data is as follows:

[0150] SS1: Set the temperature and humidity monitoring points:

[0151] Selection of location for monitoring points in basement: Select different areas of the basement to set monitoring points, including entrances, deep areas, corners, and areas where important equipment or items are stored;

[0152] Quantity and distribution: Determine the quantity and distribution of monitoring points based on the size and layout of the basement;

[0153] Monitoring equipment: Select temperature and humidity sensors equipped with data recording function to record data in real time;

[0154] SS2: Selection of outdoor monitoring point locations: Select representative outdoor areas to set up monitoring points, including open areas and around buildings;

[0155] SS3: Data collection and real-time recording. The monitoring equipment can record temperature and humidity data in real time and automatically upload them to the data management system.

[0156] Data analysis trend analysis: Analyze the changing trend of temperature and humidity by comparing historical data and real-time monitoring data;

[0157] SS4: Abnormal detection, set temperature and humidity thresholds. When the data exceeds the threshold, an alarm is automatically triggered, and relevant personnel are notified to handle it or control the operation of relevant dehumidification equipment for dehumidification;

[0158] Rationality of setting temperature and humidity monitoring points

[0159] Comprehensive coverage: Monitoring points are set up in different areas of the basement, including the entrance, deep inside, corners, and areas where important equipment or items are stored. This can fully reflect the temperature and humidity conditions in the basement and ensure the accuracy and representativeness of the monitoring data.

[0160] Highly targeted: The selection of outdoor monitoring points also takes into account representative areas, such as open areas and surrounding areas of buildings, which helps to analyze the impact of the outdoor environment on the temperature and humidity of underground garages and provide a basis for further optimizing the garage environment.

[0161] Reasonable quantity and distribution: The number and distribution of monitoring points are determined according to the size and layout of the basement, which not only ensures the comprehensiveness of monitoring but also avoids waste of resources.

[0162] Convenience of data collection and real-time recording

[0163] 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.

[0164] High data accuracy: Real-time monitoring data can accurately reflect the temperature and humidity conditions of the basement and outdoor environment, providing a reliable basis for subsequent data analysis.

[0165] In-depth data analysis and trend analysis

[0166] Comparison of historical data and real-time monitoring data: By comparing historical data and real-time monitoring data, we can analyze the changing trends of temperature and humidity, help discover potential environmental problems, and provide a basis for formulating response measures.

[0167] Abnormal detection and alarm: Set the temperature and humidity threshold. When the data exceeds the threshold, the alarm is automatically triggered and the relevant personnel are notified to handle it or control the operation of the relevant dehumidification equipment for dehumidification. This abnormal detection mechanism can respond to environmental changes in a timely manner to ensure the stability and safety of the garage environment.

[0168] Optimize decision-making and resource utilization efficiency

[0169] Optimization decision 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.

[0170] Energy saving and emission reduction: Through real-time monitoring and data analysis, abnormal temperature and humidity problems can be discovered and resolved in a timely manner, avoiding unnecessary energy waste and environmental pollution, and achieving the goal of energy saving and emission reduction.

[0171] In summary, the specific process of monitoring temperature and humidity and analyzing the monitoring data provides a scientific and efficient method for the management of temperature and humidity in underground garages and outdoor environments through reasonable setting of monitoring points, real-time data collection, in-depth analysis of trends and anomaly 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.

[0172] When abnormalities are found in the monitoring data analysis, the specific process of performing dehumidification prompts and dehumidification control is as follows:

[0173] Collecting humidity information outside and inside the underground garage;

[0174] 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 air curtain machines at the entrance and exit of the underground garage;

[0175] 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 dehumidification equipment in the underground garage to operate the dehumidification operation;

[0176] 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 duct of the ventilation equipment of the underground garage to ventilate and dehumidify;

[0177] 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 the humidity inside, the intelligent control system will immediately generate control information and 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 high-humidity air from entering the garage, thereby maintaining the stability of the humidity inside the garage.

[0178] When the humidity inside and outside the underground garage exceeds the preset value, the control system will immediately generate control information and start the dehumidification equipment to perform 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.

[0179] It also achieves high efficiency and energy saving, optimizes resource utilization, and intelligently selects ventilation and dehumidification. When the humidity outside the underground garage is detected to be less than the preset value, and the humidity inside is greater than the preset value, the control system will choose to start the blower and film duct of the ventilation equipment for ventilation and dehumidification. This strategy can use the low-humidity air outside to reduce the humidity inside the garage, while avoiding unnecessary operation of the dehumidification equipment, thereby achieving high efficiency and energy saving.

[0180] Through the intelligent control system, the operation time and intensity of the dehumidification equipment can be accurately controlled to avoid energy waste and equipment loss caused by excessive dehumidification. This helps to reduce operating costs and improve resource utilization efficiency.

[0181] Improve garage environment, ensure safety, and improve garage air quality: The ventilation and dehumidification process not only helps reduce the humidity inside the garage, but also improves air quality and reduces the growth of harmful substances such as mold and bacteria. This helps provide a healthier and more comfortable parking environment.

[0182] Ensure the safety of equipment and items: Underground garages may store important equipment and items, such as vehicles and electrical equipment. Excessive humidity can damage these equipment and items. Through the intelligent dehumidification control system, abnormal humidity problems can be discovered and handled in a timely manner, thereby ensuring the safety of equipment and items.

[0183] When abnormalities are found in the monitoring data analysis, the specific process of dehumidification prompts and dehumidification control is carried out. Through intelligent response, efficient energy saving and optimized resource utilization, the environmental quality of the underground garage is effectively improved, the safety of equipment and items is guaranteed, and the resource utilization efficiency is also improved. This process is of great significance to improving the management level and user experience of underground garages.

[0191] Check the water level in the water collection well regularly to ensure that it does not exceed the warning line and clean up the debris and silt in the water collection well;

[0192] 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 whether the joints of the waterproof layer are firm; check the aging of the waterproof layer material;

[0193] 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 based on the monitoring data;

[0194] Regularly conduct on-site inspections of the basement to observe whether there is moisture and mildew;

[0195] Check the operating status of dehumidification equipment and ventilation equipment to ensure they are working properly;

[0196] Adjust dehumidification control strategies based on assessment results and on-site inspections, including increasing the number of dehumidifiers and adjusting ventilation frequency;

[0197] Regularly review and optimize the dehumidification control strategy to ensure it meets the actual needs of the basement;

[0198] The above process extends the life of the equipment. Regular cleaning, inspection and maintenance of dehumidifiers and ventilation equipment can promptly detect and deal with potential faults and extend the service life of the equipment.

[0199] Improve equipment efficiency: Well-maintained equipment can maintain efficient operation, reduce energy consumption, and improve dehumidification and ventilation effects.
