Abstract
Description
Technical Field
[0001] This invention relates to the field of control and analysis technology, and more specifically, to a constant temperature and humidity capillary air conditioning system with dual cold source dehumidification for fresh air. Background Technology
[0002] As people's requirements for the comfort and health of their living environment continue to increase, the limitations of traditional air conditioning systems in terms of temperature and humidity control accuracy (only able to achieve ±3℃ temperature fluctuation and ±10% humidity fluctuation, which is difficult to meet the precise requirements of ±2℃ temperature and 40%-60% relative humidity in medical, museum and other scenarios), energy consumption (relying on forced convection heat exchange and a single cold source, with COP values mostly between 2 and 3, resulting in low energy utilization efficiency), and indoor air quality (only simple filtration, which cannot effectively control CO2 concentration and fresh air exchange, easily causing indoor air pollution) are becoming increasingly prominent.
[0003] With the rapid advancement of innovations in radiant heat exchange technology, dual-cold source synergistic control technology, and fresh air pretreatment technology, these technological breakthroughs have made it possible to solve the pain points of traditional systems. Therefore, the industry has begun to explore combining capillary network radiant terminals with fresh air dual-cold source dehumidification systems to create more efficient and precise indoor environmental control solutions. However, due to factors such as differences in building space functional zoning (e.g., bedrooms, living rooms, and kitchens in residences, and open office areas and enclosed meeting rooms in office spaces), different personnel activity densities (e.g., the high density of people in meeting rooms during peak hours leads to a sharp increase in CO2 and humidity, while the parameters in bedrooms are more stable at night due to less personnel activity), and uneven distribution of heat load in the building envelope (e.g., areas near the exterior walls are greatly affected by outdoor temperatures, while the heat load in the core area is more stable), the industry has begun to explore combining capillary network radiant terminals with fresh air dual-cold source dehumidification systems to create more efficient and precise indoor environmental control solutions.
[0004] During the operation and adjustment of the constant temperature and humidity capillary air conditioning fresh air dual cold source dehumidification system, it is usually necessary to collect real-time environmental parameters (such as temperature, humidity, CO2 concentration, etc.) in multiple indoor areas, and then compare these real-time environmental parameters with preset target thresholds to determine whether it is necessary to adjust the system's cold and heat source output, fresh air volume, capillary network supply and return water temperature and other control parameters.
[0005] However, due to significant differences in the functional attributes of different areas within a building space (such as bedrooms and living rooms in residences, and open office areas and meeting rooms in offices), personnel density (such as higher heat and humidity generation in meeting rooms when people are gathered, and more stable parameters when people are sparse in corridors), and heat exchange characteristics of the building envelope (such as areas near the exterior walls being greatly affected by outdoor temperature and humidity, and core areas being less affected by the outside world), the real-time environmental parameters (such as temperature, humidity, and CO2 concentration) corresponding to different areas vary significantly. This further leads to situations where it is impossible to determine which area's parameters should be used as the core benchmark and target threshold for accurate comparative analysis. If only parameters from a single area are selected as a reference, it is easy for parameters in other areas to deviate from the target threshold without being adjusted in time, ultimately affecting the overall comfort and stability of the indoor environment. This cannot meet the high-precision environmental control requirements of various scenarios such as medical operating rooms, museums, and high-end residences. In view of this, we propose a constant temperature and humidity capillary air conditioning fresh air dual cold source dehumidification system. Summary of the Invention
[0006] The purpose of this invention is to solve the problem that in traditional constant temperature and humidity capillary air conditioning dual-source dehumidification systems, when operating and adjusting, the real-time environmental parameters of different areas of the room are significantly different, making it difficult to determine the core benchmark parameters and the target threshold for accurate comparison and analysis. Selecting parameters for only one area can easily lead to other area parameters deviating from the target threshold without being adjusted in time, thus affecting the overall indoor environmental comfort and stability, and failing to meet the high-precision environmental control requirements in multiple scenarios.
[0007] To achieve the above objectives, this invention provides a constant temperature and humidity capillary air conditioning system with dual cold source dehumidification, comprising an initial sampling and multi-region parameter acquisition module, a fusion weight calculation and environmental parameter fusion module, and a sampling frequency dynamic adjustment module, wherein:
[0008] The initial sampling and multi-region parameter acquisition module sets the initial sampling frequency, receives real-time environmental parameters, and constructs a set of multi-point parameters collected in different regions at the same sampling timestamp.
[0009] The fusion weight calculation and environmental parameter fusion module sets a target threshold, calculates the deviation of each real-time environmental parameter from the set target threshold, dynamically sets the fusion weight of real-time environmental parameters in different regions based on the deviation, and uses the fusion weight to weight the real-time environmental parameters to obtain the fused environmental parameters; compares the fused environmental parameters with the target threshold, and outputs the corresponding control signal based on the comparison result;
[0010] The sampling frequency dynamic adjustment module sorts and fuses environmental parameters into a time-series parameter set, analyzes the changing trend of the time-series parameter set, and if the fused environmental parameters in the time-series parameter set show a downward trend, the initial sampling frequency is maintained; if the fused environmental parameters in the time-series parameter set show an upward trend, the initial sampling frequency is reduced to a secondary sampling frequency.
[0011] After the fusion weight calculation and environmental parameter fusion module outputs a control signal, if it is determined again that the time series parameter set is in a downward trend, the secondary sampling frequency is increased to increase the sampling frequency until the increased sampling frequency is the same as the initial sampling frequency in the initial sampling and multi-region parameter acquisition module.
[0012] As a further improvement to this technical solution, the initial sampling and multi-region parameter acquisition module sets an initial sampling frequency and receives real-time environmental parameters from different regions collected by acquisition sensors deployed in key indoor areas. The real-time environmental parameters include temperature parameters and air quality indicators. Then, it constructs a set of multi-point parameters collected in different regions at the same sampling timestamp in a fixed order.
[0013] The beneficial effect of the above-mentioned further solution is that, by setting an initial sampling frequency, core environmental parameters of multiple key indoor areas can be comprehensively collected at a stable and uniform sampling frequency. This ensures that the acquired real-time environmental parameters are synchronous and complete, providing a basic and reliable data source for subsequent accurate analysis of differences in real-time environmental parameters in various areas, judgment of the overall environmental status, and formulation of targeted adjustment strategies. It avoids misjudgment of the indoor environment due to chaotic sampling frequency or missing regional data, thereby ensuring the accuracy and effectiveness of subsequent adjustment of the constant temperature and humidity capillary air conditioning fresh air dual cold source dehumidification system, and helping to maintain the indoor environment in a comfortable and healthy state.
[0014] Based on the above technical solution, the present invention can be further improved as follows: the fusion weight calculation and environmental parameter fusion module includes a fusion weight calculation and environmental parameter fusion subunit and a threshold comparison and control signal output unit; the fusion weight calculation and environmental parameter fusion subunit sets a target threshold, calculates the deviation between the real-time environmental parameters collected in different regions at the same sampling timestamp and the set target threshold, and dynamically sets the fusion weight of the real-time environmental parameters in different regions based on the deviation; the real-time environmental parameters collected in different regions at the same sampling timestamp are weighted and fused to obtain fused environmental parameters; the threshold comparison and control signal output unit is used to compare the target threshold and the fused environmental parameters and output different control commands.
[0015] As a further improvement to this technical solution, the fusion weight calculation and environmental parameter fusion subunit receives a set of multi-point parameters collected from different regions at the same sampling timestamp, sets a target threshold, and subtracts the target threshold from each real-time environmental parameter in the multi-point parameter set in turn to obtain the deviation between the real-time environmental parameter and the target threshold. The absolute value of the deviation is set as the deviation modulus.
[0016] Then, the deviation magnitude of each real-time environmental parameter from the target threshold is added together to obtain the denominator for calculating the fusion weight. The deviation magnitude of each real-time environmental parameter from the target threshold is then used as the denominator and divided by the denominator to obtain the fusion weight of each real-time environmental parameter for each region under the same sampling timestamp.
[0017] As a further improvement to this technical solution, the fusion weight calculation and environmental parameter fusion subunit sequentially multiplies each real-time environmental parameter in the multi-point parameter set by its corresponding fusion weight to obtain multiple fusion products. Then, the multiple fusion products are added together to obtain the fused environmental parameters, which include actual temperature parameters and actual air quality indicators.
[0018] The beneficial effect of the above-mentioned further solution is that the fusion weight calculation and environmental parameter fusion subunit allocates fusion weights by considering the degree of deviation between the real-time environmental parameters of different regions and the target threshold. This allows regions that deviate more significantly from the target threshold to have a greater influence in the calculation of fused environmental parameters, thereby making the obtained fused environmental parameters more accurately reflect the status of regions that need to be focused on and adjusted. This avoids ignoring the environmental problems of key regions due to simple averaging or the dominance of parameters in a single region, and provides a more reliable basis for the subsequent output of targeted control signals by the system. In turn, it improves the accuracy and effectiveness of the constant temperature and humidity capillary air conditioning fresh air dual cold source dehumidification system in controlling the indoor environment, ensuring that the parameters of the indoor environment are more stably close to the target threshold, and meeting the needs of high precision and high comfort of the indoor environment in multiple scenarios.
[0019] Based on the above technical solution, the present invention can be further improved as follows: the threshold comparison and control signal output unit receives the target threshold, including the temperature target and the air target; compares and fuses the environmental parameters with the target threshold, specifically: comparing the actual temperature parameters with the temperature target, and the actual air quality index with the air target;
[0020] During summer cooling, if the actual temperature parameter is greater than the target temperature, a control signal for cooling will be output.
[0021] During winter heating, if the actual temperature parameter is greater than the temperature target, it is determined that the actual temperature parameter meets the temperature target, and no control signal is output.
[0022] If the actual air quality index is greater than the air quality target, the output will include a control signal corresponding to increasing the fresh air replacement frequency.
[0023] The beneficial effects of the above-mentioned further solution are that by comparing and integrating environmental parameters with target thresholds, and then comparing the actual situation of air quality with the target thresholds in different seasons (summer cooling, winter heating), the threshold comparison and control signal output unit accurately and differentially outputs control signals. In summer, timely cooling ensures a cool and comfortable environment; in winter, unnecessary adjustments are avoided to save energy and maintain a warm and suitable temperature; when air quality is substandard, the indoor air quality is improved by increasing the fresh air replacement frequency. Thus, the constant temperature and humidity capillary air conditioning fresh air dual cold source dehumidification system can efficiently and accurately adjust the indoor environment in different scenarios, meeting people's needs for temperature comfort, ensuring healthy indoor air quality, and making reasonable use of energy, avoiding resource waste caused by ineffective adjustments.
[0024] Based on the above technical solution, the present invention can also be improved as follows: the sampling frequency dynamic adjustment module receives the fusion environment parameters in the threshold comparison and control signal output unit, sorts the fusion environment parameters corresponding to different sampling timestamps according to the time sequence to form a time sequence parameter set, analyzes the fusion environment parameters corresponding to different sampling nodes, and adjusts the initial sampling frequency in the initial sampling and multi-region parameter acquisition module.
[0025] After the threshold comparison and control signal output unit outputs the control signal, the sampling frequency dynamic adjustment module first numerically processes the sampling timestamps in the time sequence parameter set, recording the first timestamp as one, the second as two, and so on until the last timestamp; the corresponding fusion environment parameters are recorded sequentially to construct a linear regression model; in the linear regression model, the slope product sampling timestamp is added to the intercept to obtain the fusion environment parameters;
[0026] The slope in the linear regression model is calculated as follows: The numerator is obtained by multiplying the total number of timestamps by the sum of the products of each sampling timestamp and its corresponding fusion environment parameter, and then subtracting the product of the sum of all sampling timestamps and the sum of all fusion environment parameters. The denominator is obtained by multiplying the total number of sampling timestamps by the sum of the squares of each sampling timestamp, and then subtracting the square of the sum of all sampling timestamps. The slope in the linear regression model is obtained by dividing the numerator by the denominator.
[0027] As a further improvement to this technical solution, the sampling frequency dynamic adjustment module sets multiple consecutive sampling timestamps and calculates the difference between adjacent fusion environment parameters within multiple sampling timestamps.
[0028] If the slope is greater than 0 and more than half of the sum of differences is greater than 0, then the fusion environment parameters within the time series parameter set are judged to be on an upward trend; if the slope is less than or equal to 0 and more than half of the sum of differences is less than or equal to 0, then the fusion environment parameters within the time series parameter set are judged to be on a downward trend.
[0029] As a further improvement to this technical solution, when the sampling frequency dynamic adjustment module determines that the fused environmental parameters in the time-series parameter set are showing a downward trend, it keeps the initial sampling frequency in the initial sampling and multi-region parameter acquisition modules unchanged.
[0030] When it is determined that the fused environmental parameters within the time-series parameter set are on an upward trend, the initial sampling frequency is reduced to the secondary sampling frequency based on the threshold comparison and the corresponding slope of the time-series parameter set in the control signal output unit.
[0031] After the threshold comparison and control signal output unit outputs the control signal, if the timing parameter set is judged... When the trend is downward, the secondary sampling frequency is increased according to the slope to increase the sampling frequency, and the secondary sampling frequency is decreased until the sampling frequency is increased to be the same as the initial sampling frequency in the initial sampling and multi-region parameter acquisition module.
[0032] The beneficial effects of the above-mentioned further scheme are that, based on the real-time changing trend of the fused environmental parameters, the sampling frequency is dynamically and accurately adjusted. When the fused environmental parameters show a downward trend, the initial sampling frequency is maintained, which can stably and continuously monitor indoor environmental parameters without consuming additional system resources, providing basic data for subsequent adjustments. When the parameters show an upward trend, the initial sampling frequency is reduced to a secondary sampling frequency, which can effectively avoid excessive energy consumption of the acquisition sensors and redundant burden on the data processing stage caused by an excessively high initial sampling frequency, achieving rational use of resources, while ensuring effective tracking of the convergence process of environmental parameters towards the target threshold; and in the threshold comparison and control... After the control signal output unit outputs the control signal, if the fused environmental parameters show a downward trend, the secondary sampling frequency is increased until it matches the initial sampling frequency. This allows for more sensitive capture of subtle changes in environmental parameters, enabling the threshold comparison and control signal output unit to output the corresponding control signal more promptly. Consequently, the constant temperature and humidity capillary air conditioning fresh air dual-source dehumidification system achieves a balance between energy saving and efficient regulation while ensuring accurate monitoring of the indoor environment. This reduces unnecessary energy waste and allows for rapid response when needed, ensuring that the indoor environment is stably maintained in a comfortable and healthy state. This meets the dual requirements of high precision and low energy consumption for indoor environmental regulation in different scenarios.
[0033] Based on the above technical solution, the present invention can be further improved as follows: In the sampling frequency dynamic adjustment module, the initial sampling frequency is reduced according to the slope to obtain the secondary sampling frequency: the adjustment coefficient of the slope corresponding to the initial sampling frequency is multiplied by the slope, then the corresponding product is subtracted, and then multiplied by the initial sampling frequency again to obtain the secondary sampling frequency.
[0034] To increase the sampling frequency by increasing the slope, the adjustment coefficient corresponding to the second sampling frequency is multiplied by the absolute value of the slope, and then the product is multiplied again by the second sampling frequency to obtain the increased sampling frequency.
[0035] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

Detailed Implementation
[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0040] This technical solution is designed for high-end residences, health and wellness buildings, and other scenarios with stringent requirements for temperature and humidity environments. It proposes a constant temperature and humidity capillary air conditioning and fresh air dual-cold source dehumidification system, which aims to achieve precise control of indoor temperature ±0.5℃ and relative humidity ±5%, while reducing energy consumption by more than 28%. It also ensures indoor air cleanliness through full replacement fresh air, creating an ideal living environment with constant temperature, constant humidity, constant cleanliness, and low noise.
[0041] The working principle of the above-mentioned constant temperature and humidity capillary air conditioning dual-source dehumidification system for fresh air is as follows when operating in different scenarios:
[0042] Summer Cooling: The capillary network air conditioning system uses water as a heat source and cold source, delivering low-temperature water (16-18℃) to a capillary network (2-5mm diameter, 100-200mm spacing) installed in the indoor ceiling or walls. Through ceiling-mounted low-temperature differential heat exchange technology, the low-temperature capillaries primarily use radiation heat exchange (over 70%), supplemented by convection heat exchange, to absorb heat from the indoor air, slowly lowering the indoor temperature to a comfortable range of 24-26℃. Simultaneously, because it avoids the blowing convection of traditional air conditioners, it eliminates the problems of uneven temperature differences and strong drafts, and the operating noise is ≤30dB.
[0043] Winter heating: Switch to 32-35℃ warm water circulation input into the capillary network. The warm water radiates heat outward through the capillary tubes, evenly raising the indoor temperature to 20-22℃. Compared with traditional radiators or air conditioning heating, capillary radiant heat exchange can keep the indoor horizontal temperature difference ≤2℃ and eliminate the feeling of dryness.
[0044] Fresh air purification stage: Outdoor fresh air first passes through a three-stage filtration system (pre-filter G4 + medium-efficiency F8 + high-efficiency H13, the novelty search report mentions "imported filter materials"), with a filtration efficiency of ≥99.97%, which can remove pollutants such as PM2.5, pollen, and dust; at the same time, the system uses "layered airflow organization" to prevent unfiltered air from directly entering the room, laying a clean foundation for subsequent dehumidification and heat exchange.
[0045] Dual-source dehumidification stage: Overcoming the limitation of excessively cold air supply after traditional single-source dehumidification, it adopts a two-stage cold source synergistic dehumidification:
[0046] The first cold source (ethylene glycol solution, temperature 5-7℃): pre-cools and dehumidifies the purified fresh air, quickly removing more than 80% of the latent heat (moisture) in the air, reducing the relative humidity of the fresh air to below 50%.
[0047] The second cold source (capillary system return water, temperature 18-20℃): reheats the dehumidified low-temperature fresh air (about 12-14℃) and adjusts the supply air temperature to 22-24℃ to avoid indoor temperature fluctuations caused by low-temperature fresh air. At the same time, it recovers the waste heat of the capillary system and reduces energy consumption.
[0048] Full replacement circulation stage: The treated clean fresh air is delivered into the room through the ground air supply outlet. Because the density of the fresh air is slightly greater than that of the indoor air, a fresh air lake is formed and it slowly flows upward. At the same time, the polluted air containing CO2 and odors in the room is discharged through the top exhaust outlet, realizing a full replacement circulation of ground supply and top return air. During this process, a slight positive pressure is formed in the room, which can effectively block the infiltration of unfiltered pollutants from the outside, further ensuring air cleanliness.
[0049] To ensure that the constant temperature and humidity capillary air conditioning system with dual cold source dehumidification can output different control signals more accurately during operation, and to ensure that real-time environmental parameters can consistently and rapidly move towards the set target threshold, To approximate and avoid excessive fluctuations in real-time environmental parameters, refer to... Figure 1 As shown, the constant temperature and humidity capillary air conditioning fresh air dual-cold source dehumidification system of the present invention includes an initial sampling and multi-region parameter acquisition module 100, a fusion weight calculation and environmental parameter fusion module 200, and a sampling frequency dynamic control module 300, wherein:
[0050] The initial sampling and multi-region parameter acquisition module 100 sets the initial sampling frequency. (such as sampling frequency) =1 time / minute), and receives real-time environmental parameters corresponding to different areas by sensors deployed in key indoor areas (such as living room and bedroom), and then constructs different areas at the same sampling timestamp. The following is a collection of parameters from multiple points:
[0051] ;
[0052] in For the first Each region corresponds to a sensor that collects data at the sampling timestamp. Real-time environmental parameters collected in real time. ,in For temperature parameters, For air quality indicators;
[0053] Specific data acquisition sensors include, but are not limited to, temperature and humidity sensors and CO2 sensors.
[0054] This invention takes into account the real-time environmental parameters of different areas in actual indoor environmental control scenarios. (For example, temperature, humidity, etc.) often differ, so in order to obtain real-time environmental parameters from different regions... This makes the fusion environment parameters after fusion... It can more accurately reflect the current real-time environmental parameters, and then output different control signals based on the current real-time environmental parameters. Therefore, the fusion weight calculation and environmental parameter fusion module 200 includes a fusion weight calculation and environmental parameter fusion subunit 210 and a threshold comparison and control signal output unit 220, wherein the fusion weight calculation and environmental parameter fusion subunit 210 is used to set the target threshold. Calculate the sampling timestamps of different regions. Real-time environmental parameters collected below With set target threshold The deviation is used to dynamically set real-time environmental parameters for different areas. The fusion weights are then used to weight and fuse different regions at the same sampling timestamp. Real-time environmental parameters collected below , obtain fusion environment parameters ;
[0055] The threshold comparison and control signal output unit 220 is used to compare the target threshold. and integration of environmental parameters Output different control commands;
[0056] Specifically:
[0057] The fusion weight calculation and environmental parameter fusion subunit 210 receives data from different regions at the same sampling timestamp. Multi-point parameter set collected below Set target threshold Calculate real-time environmental parameters With target threshold deviation Deviation modulus The larger the value, the more likely it is to indicate the first... Real-time environmental parameters of each region Deviation from target threshold The more significant the deviation, the more directly it will affect the usability of the area (for example, if the temperature in a residential area deviates from the comfortable range, people will feel uncomfortable; if the humidity in a storage area deviates from the appropriate range, items will be damaged). Real-time environmental parameters of each region The more important it is, the more attention and adjustment are needed.
[0058] Therefore, the fusion weight calculation and environmental parameter fusion subunit 210 are based on the deviation vector magnitude. The size is a real-time environmental parameter Assign corresponding fusion weights ;
[0059] And through fusion weights Deviate from the target threshold The more severely affected areas wield greater influence during the integration process;
[0060] Then, a fusion weighting method is adopted. Weighted fusion of multi-point parameter sets collected from various regions , obtain fusion environment parameters ;
[0061] For example, in winter heating, the first... Real-time temperature parameters of each area Distance from temperature target The farther away, the higher the real-time temperature parameter. The greater the deviation from the desired comfortable heating temperature, the colder the people in the area will feel (which does not meet the requirement of ensuring warmth and comfort in winter heating). In this case, the fusion weight is calculated and analyzed by the fusion weight subunit 210 of the environmental parameters. , fusion temperature parameter set Obtain actual temperature parameters Compare with actual temperature parameters With temperature target The threshold comparison and control signal output unit 220 determines whether a control signal needs to be output. If the threshold comparison and control signal output unit 220 outputs a control signal, it is used to increase the water supply temperature. This is because when the water supply temperature increases, the capillary network can transfer more heat to the room through heat exchange, thereby increasing the actual temperature parameter. To meet the heating needs in winter;
[0062] Meanwhile, because the heat exchange in the capillary network is relatively uniform and continuous, heat can be transferred and distributed relatively stably in all areas of the room. Therefore, during the heat exchange process, the actual temperature parameter in a certain area will not change. In cases of significant differences, ensure overall indoor temperature balance.
[0063] The target threshold in the fusion weight calculation and environmental parameter fusion subunit 210 Specifically, the fusion environment parameters in the fusion weight calculation and environmental parameter fusion subunit 210 can be viewed remotely via mobile device. Then set the target threshold. .
[0064] Threshold comparison and control signal output unit 220 receives the target threshold. This includes temperature targets. air targets Comparison and fusion of environmental parameters With target threshold Specifically:
[0065] Integrating environmental parameters Including actual temperature parameters Actual air quality indicators Compare the actual temperature parameters one by one. and temperature target Actual air quality indicators and air targets ;
[0066] When cooling in summer, if the actual temperature parameters >Temperature Target The output includes control signals related to cooling, such as increasing the cold water flow rate of the capillary system or decreasing the supply water temperature.
[0067] During winter heating, if the actual temperature parameters >Temperature Target Then determine the actual temperature parameters. Meets temperature target No control signal is output;
[0068] If the actual air quality index >Air targets The output includes control signals corresponding to increasing the fresh air replacement frequency to ensure indoor air quality.
[0069] The sampling frequency dynamic adjustment module 300 receives the threshold comparison and control signal output unit 220, which contains the fusion environment parameters. And sort the different sampling timestamps according to the time series. Corresponding fusion environment parameters Forming a set of timing parameters ,in ;

[0071] After the threshold comparison and control signal output unit 220 outputs the control signal, the sampling frequency dynamic adjustment module 300 is used to analyze the time series parameter set. Trends in the set of numerical time series parameters Sampling timestamp ,in Sampling timestamp The corresponding fusion environment parameters are: Constructing a linear regression model:

The difference and If the slope >0 and The difference and If >0, then determine the set of timing parameters. Internal fusion environment parameters It shows an upward trend; if the slope ≤0 and The difference and If ≤0, then determine the set of timing parameters. Internal fusion environment parameters It shows a downward trend;
[0075] Timing parameter set Internal fusion environment parameters When the trend is downward, it indicates that the environmental parameters are being integrated. Instead of being effectively regulated, it gradually moved away from the target threshold. Therefore, the initial sampling frequency in the multi-region parameter acquisition module 100 is maintained. No adjustments will be made;
[0076] Timing parameter set Internal fusion environment parameters When the threshold comparison and control signal output unit 220 are on the constant temperature and humidity capillary air conditioning fresh air dual cold source dehumidification system, the system's adjustment mechanism (such as heat exchange in the capillary network, ventilation of the fresh air system, etc.) begins to function, thus addressing deviations from the target threshold. The region was effectively adjusted to improve the parameters of the fusion environment after fusion. It can continuously and stably move towards the target threshold. Convergence reflects that the adjustment strategy and implementation process are effective and can gradually improve the indoor environment, making it closer to the comfortable and suitable state that people expect;
[0077] Timing parameter set When the trend is upward, the environmental parameters are integrated. Heading toward the target threshold Sustained and stable convergence, to avoid initial sampling frequency Excessive power consumption leads to unnecessary energy consumption by the acquisition sensors and redundant data processing in the fusion weight calculation and environmental parameter fusion subunit 210, resulting in resource waste. Therefore, based on the threshold comparison and control signal output unit 220, the timing parameter set is used to determine the optimal power consumption. The corresponding slope Reduce initial sampling frequency Secondary sampling frequency ,in slope Corresponding initial sampling frequency Adjustment coefficient, slope A set of timing parameters Linear regression model when the trend is upward Mid-slope reflects the parameters of the fusion environment. The rate of increase over time;
[0078] By reducing the initial sampling frequency Secondary sampling frequency This ensures that environmental parameters can be effectively tracked and integrated. To target threshold Under the premise of convergence, unnecessary resource consumption is reduced, enabling the system to operate in a more energy-efficient and efficient manner, while also avoiding problems such as reduced data processing efficiency caused by excessive data generated due to excessive sampling frequency;
[0079] After the threshold comparison and control signal output unit 220 outputs the control signal, if the timing parameter set is judged... When the trend is downward, it indicates that the system's adjustment mechanism is not functioning effectively, and the integrated environmental parameters are gradually moving away from the target threshold. At this point, in order to more sensitively monitor changes in environmental parameters and ensure that the threshold comparison and control signal output unit 220 can output the corresponding control signal in a timely manner, the slope is used to determine the appropriate control signal. Increase the second sampling frequency To increase the sampling frequency ,in slope Corresponding secondary sampling frequency The adjustment coefficient, A set of timing parameters Linear regression model when the trend is downward Medium slope, slope absolute value Reflecting integrated environmental parameters The magnitude of the rate of decrease over time; reducing the secondary sampling frequency. Until the sampling frequency is increased The initial sampling frequency in the initial sampling and multi-region parameter acquisition module 100 This consistency allows the data acquisition sensor to collect real-time environmental parameters corresponding to different areas at a reasonable sampling frequency. The changes allow the subsequent timely threshold comparison and control signal output unit 220 to adjust the control signal and improve real-time environmental parameters. Provide reliable data support.
