Description

Technical Field

[0001] The present invention belongs to the field of air conditioning and dehumidification, and relates to an adaptive control technology for a rotary dehumidifier using electric heating, steam heating and high-temperature heat pump condensation heat heating regeneration, and specifically is an adaptive control system and method for a rotary dehumidifier. Background Art

[0002] With the improvement of industrial production and quality of life, the demand for air humidity control is increasing. Especially in the fields of precision manufacturing, medicine, food processing, and electronics, precise control of humidity is crucial to product quality and production efficiency. Traditional rotary dehumidifiers usually adopt a fixed operating mode and cannot be dynamically adjusted according to changes in the environment and the inside of the equipment. This fixed mode still operates at high power when the humidity requirement is not high or the ambient humidity is low, resulting in high energy consumption; when environmental conditions change, the fixed mode is difficult to ensure a stable dehumidification effect, resulting in unstable dehumidification effect; long-term high-load operation may cause increased equipment wear and shorten service life, resulting in the problem of shortened equipment life. Therefore, users have put forward higher requirements for the automation and intelligence level of dehumidification equipment.

[0003] At present, most adaptive control systems used for rotary dehumidifiers find it difficult to adaptively dehumidify according to the ambient humidity during dehumidification. When the ambient humidity changes, the control system with fixed parameters cannot be adjusted in time, which may lead to over-dehumidification or under-dehumidification. At the same time, most adaptive control systems used for rotary dehumidifiers ignore the fact that the rotation speed of the dehumidification wheel and the heating of the heating device have a superimposed drying effect. For example, if both increase at the same time, the heating effect will be greater than the required effect, which may cause the burning of the wheel material or energy loss. If both decrease at the same time, the heating effect will be less than the required effect. At this time, the drying of the dehumidification wheel may not meet the requirements, resulting in a reduction in the dehumidification effect of the room.

[0004] Therefore, the present invention discloses an adaptive control system and method for a rotary dehumidifier, which are used to solve the above technical problems. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 2 , the first aspect of the present invention provides an adaptive control system for a rotary dehumidifier, comprising: a rotary control module, and a data collection module, an auxiliary device control module and a database connected thereto; Data collection module: used to obtain target data through distributed monitoring equipment, and analyze the target data to obtain characteristic values ​​of the target data; wherein the target data includes indoor humidity, the wheel humidity of the primary dehumidification wheel and the secondary dehumidification wheel; the wheel humidity is the wheel humidity of the dehumidification zone, and the characteristic values ​​of the target data include indoor characteristic humidity, the first characteristic humidity of the primary dehumidification wheel and the second characteristic humidity of the secondary dehumidification wheel; Wheel control module: dynamically adjusts the speed of the secondary dehumidification wheel based on the indoor characteristic humidity, and dynamically adjusts the speed of the primary dehumidification wheel based on the first characteristic humidity and the second characteristic humidity; Auxiliary device control module: based on the steering device, the dry air passing through the dehumidification zone of the secondary dehumidification wheel is diverted into dry air one and dry air two; based on the dry air one information, the second characteristic humidity and the rotation speed of the secondary dehumidification wheel, the heating power of the secondary heating device is dynamically adjusted, and the heating power of the preliminary heating device is adjusted based on the dry air three information and the rotation speed of the preliminary dehumidification wheel; based on the aggregation device, the indoor air and the outdoor air passing through the dehumidification zone of the preliminary dehumidification wheel are aggregated and cooled; wherein, dry air three is obtained by dry air one through the secondary dehumidification wheel, the dry air one information includes the flow rate and humidity of dry air one, and the dry air three information includes the flow rate and humidity of dry air three; the steering device is used to divert the dry air passing through the secondary dehumidification wheel into dry air one and dry air two.

[0023] See also Figure 4 The dehumidification zone and regeneration zone of the rotary dehumidifier are separated by a partition. The outdoor air is first dehumidified by the dehumidification zone of the primary dehumidification wheel, and then polymerized and cooled with the indoor air at the polymerization device. The polymerized air is then dehumidified by the dehumidification zone of the secondary dehumidification wheel and then diverted into dry air one and dry air two through the steering device. Dry air two is sent into the room, and dry air one is sent to the secondary heating device for heating and then used to dry the hygroscopic material in the regeneration zone of the secondary dehumidification wheel. Then dry air three is obtained. Dry air three is heated by the primary heating device and then used to dry the hygroscopic material in the regeneration zone of the primary dehumidification wheel and then discharged outdoors.

[0024] It should be noted that the steering device is used to divert the dry air passing through the secondary dehumidification wheel into dry air one and dry air two.

[0025] It should be noted that the polymerization device is a device for polymerizing the outdoor air and indoor air that have passed through the preliminary dehumidification wheel and cooling the polymerized air.

[0026] In this application, target data is obtained through distributed monitoring devices, including: The humidity in the room is obtained by means of humidity sensors distributedly installed in the room to be dehumidified, and the humidity is marked as indoor humidity; the wheel humidity of the primary dehumidification wheel is obtained by means of a humidity sensor installed on the primary dehumidification wheel, and the wheel humidity of the secondary dehumidification wheel is obtained by means of a humidity sensor installed on the secondary dehumidification wheel; the indoor humidity, the wheel humidity of the primary dehumidification wheel and the wheel humidity of the secondary dehumidification wheel are integrated to obtain target data; wherein, the wheel humidity is the wheel humidity of the dehumidification zone.

[0027] It should be noted that the primary dehumidification wheel and the secondary dehumidification wheel rotate during the process of dehumidifying the air, so the wheel humidity obtained is the wheel humidity actively emitted when the current humidity sensor rotates to the dehumidification area.

[0028] In this application, the target data is analyzed to obtain characteristic values ​​of the target data, including: Integrate the indoor humidity into the A1 humidity group, integrate the wheel humidity of the primary dehumidification wheel into the A2 humidity group, integrate the wheel humidity of the secondary dehumidification wheel into the A3 humidity group, and set a number for each humidity group; Extract each humidity group based on the number of the humidity group, mark the extracted humidity group as the humidity group to be analyzed, obtain the variance of the humidity group to be analyzed, and judge whether the variance of the humidity group to be analyzed is greater than the variance critical value corresponding to the humidity group to be analyzed; if yes, remove the humidity data with the largest difference from the humidity data mode in the humidity group to be analyzed, and re-judge the variance until the variance of the humidity group to be analyzed is not greater than the variance critical value corresponding to the humidity group to be analyzed, and retain the remaining humidity data of the current humidity group to be analyzed; if no, retain the humidity data of the current humidity group to be analyzed; wherein the variance critical value is obtained by manual setting; The mode DZ, percentile BW and mean PJ of the humidity data retained by the humidity group to be analyzed are extracted, and the characteristic value TZn corresponding to the humidity group to be analyzed is obtained based on the formula TZn=(δ1×DZ+δ2×BW+PJ) / 2; wherein δ1 and δ2 are both proportional adjustment coefficients greater than 0, and δ1+δ2=1, δ1≥δ2; n is the number of the humidity group, which is 1, 2 or 3; the percentile of the percentile BW is obtained by manual setting; The characteristic value TZ1 of the humidity group to be analyzed corresponding to the A1 humidity group is marked as the indoor characteristic humidity, the characteristic value TZ1 of the humidity group to be analyzed corresponding to the A2 humidity group is marked as the first characteristic humidity of the preliminary dehumidification wheel, and the characteristic value TZ1 of the humidity group to be analyzed corresponding to the A3 humidity group is marked as the second characteristic humidity of the secondary dehumidification wheel.

[0029] It is worth noting that the present invention uses percentiles when calculating eigenvalues. The added percentiles can make the acquired eigenvalues ​​adapt to the degree of bias of the data field in which the current data is located. For example, in the dehumidification field, the acquired humidity eigenvalue should be at a larger position than the data size in the data group, which can better ensure the dehumidification effect. Taking percentiles into consideration when obtaining eigenvalues ​​can improve the system's adaptability to data analysis.

[0030] It should be noted that, among the eigenvalues ​​TZn of the humidity group to be analyzed, when n=1, it indicates that the eigenvalue TZ1 is the eigenvalue corresponding to the A1 humidity group; when n=2, it indicates that the eigenvalue TZ2 is the eigenvalue corresponding to the A2 humidity group; when n=3, it indicates that the eigenvalue TZ3 is the eigenvalue corresponding to the A3 humidity group.

[0031] It should be noted that the percentile BW is the value at a specific percentile set manually; for example, if the data in the humidity group to be analyzed are sorted in ascending order, if the manually set percentile is 80%, then the data at the 80% position of the humidity group to be analyzed is the percentile of the group. If there is no data at the 80% position of the group, the data closest to the 80% position will be used as the percentile of the group.

[0032] In this application, the rotation speed of the secondary dehumidification wheel is dynamically adjusted based on the indoor characteristic humidity, including: B1: Extract the indoor characteristic humidity NTD and determine whether the indoor characteristic humidity NTD is greater than the indoor humidity threshold NYZ; if yes, adjust the speed of the secondary dehumidification wheel to the maximum value of the speed suitable range; if no, jump to B2; the indoor humidity threshold is obtained through experience setting, and the speed suitable range is obtained through manual setting; B2: Based on the formula ZS2=ZR+ZR×(β / exp((α×NYZ-NTD) / (α×NYZ))-1), the speed ZS2 of the secondary dehumidification wheel is obtained; wherein α is the manually set proportional adjustment coefficient, and the value range of α is (0,1]; β is the amplitude adjustment coefficient of the exp() function, and the value range of β is (0,2); ZR is the middle value of the appropriate speed range; B3: Determine whether the rotation speed ZS2 of the secondary dehumidification wheel is greater than the maximum value of the suitable speed range; if yes, update the value of the rotation speed ZS2 of the secondary dehumidification wheel with the maximum value of the suitable speed range; if no, jump to B4; B4: Determine whether the rotation speed ZS2 of the secondary dehumidification wheel is less than the minimum value of the suitable speed range; if yes, update the value of the rotation speed ZS2 of the secondary dehumidification wheel with the minimum value of the suitable speed range; if no, do nothing.

[0033] It is worth noting that the speed of the secondary dehumidification wheel is dynamically adjusted according to the indoor characteristic humidity. This allows the dehumidification performance of the rotary dehumidifier to change with the change of humidity in the environment, avoiding high-performance operation in a low-humidity environment and reducing energy consumption and mechanical wear. At the same time, 1 / exp() is a nonlinear function with a downward amplitude. Through this nonlinear function, the speed ZS2 of the secondary dehumidification wheel can increase with the increase of the indoor characteristic humidity NTD, and decrease with the decrease of the indoor characteristic humidity NTD. This enables the rotary dehumidifier to better adapt to the changes in different humidity environments and ensure that the dehumidification effect and energy consumption are always in the best state.

[0034] It should be noted that the suitable speed range is a defined interval used to keep the wheel within a reasonable speed range.

[0035] In this embodiment, the indoor characteristic humidity NTD=50%RH, and the indoor humidity threshold NYZ=60%RH; because the indoor characteristic humidity NTD is greater than the indoor humidity threshold NYZ, based on the formula ZS2=ZR+ZR×(β / exp((α×NYZ-NTD) / (α×NYZ))-1)=10+10×(0.98 / exp((0.9×60%RH-50%RH) / (0.9×60%RH))-1)=9.1 rpm, the speed of the secondary dehumidification wheel ZS2=9.1 rpm is obtained; wherein, in this embodiment, the proportional adjustment coefficient α is taken as 0.9, the amplitude adjustment coefficient β is taken as 0.98, and the middle value ZR of the suitable speed range is 10 rpm.

[0036] In the present application, dynamically adjusting the rotation speed of the preliminary dehumidification wheel based on the first characteristic humidity and the second characteristic humidity includes: C1: Extract the first characteristic humidity YD of the primary dehumidification wheel and the second characteristic humidity RD of the secondary dehumidification wheel, and determine whether the first characteristic humidity YD or the second characteristic humidity RD is greater than the wheel humidity threshold ZSD; if yes, adjust the speed of the primary dehumidification wheel to the maximum value of the speed suitable range; if no, jump to C2; wherein the wheel humidity threshold is obtained through experience; C2: Extract the middle value ZR of the suitable speed range, and obtain the initial dehumidification wheel speed ZS1 based on the formula ZS1=ZR×μ×exp(-|((γ1×YD+γ2×RD)-(LT×ZSD)) / (LT×ZSD)|); where γ1 and γ2 are both proportional adjustment coefficients greater than 0, and γ1+γ2=1; LT is the manually set proportional adjustment coefficient, and the value range of LT is (0,1]; μ is the amplitude adjustment coefficient of the exp() function, and the value range of μ is (0,2); C3: Determine whether the rotation speed ZS1 of the preliminary dehumidification wheel is greater than the maximum value of the suitable speed range; if yes, update the value of the rotation speed ZS1 of the preliminary dehumidification wheel with the maximum value of the suitable speed range; if no, jump to C4; C4: Determine whether the rotation speed ZS1 of the preliminary dehumidification wheel is less than the minimum value of the suitable speed range; if yes, update the value of the rotation speed ZS1 of the preliminary dehumidification wheel with the minimum value of the suitable speed range; if no, do nothing.

[0037] It is worth noting that the speed of the dehumidification wheel in this system can not only directly adjust the rotation of the dehumidification wheel to improve the dehumidification effect, but also affect the heating power of the heating device in the subsequent analysis, so as to make the dehumidification effect brought by the combined rotation of the dehumidification wheel and the heating of the heating device meet the expected range, avoiding poor dehumidification caused by too low heating effect, and burning of hygroscopic materials and increased energy consumption caused by too high heating effect, thereby improving the system's adaptability to dehumidification.

[0038] It should be noted that, when judging whether the first characteristic humidity YD or the second characteristic humidity RD is greater than the wheel humidity threshold ZSD, when one of the first characteristic humidity YD and the second characteristic humidity RD is greater than the wheel humidity threshold ZSD, the speed of the preliminary dehumidification wheel is adjusted to the maximum value of the appropriate speed range; when neither the first characteristic humidity YD nor the second characteristic humidity RD is greater than the wheel humidity threshold ZSD, jump to C2.

[0039] In this embodiment, the first characteristic humidity YD of the primary dehumidification wheel is 60%RH, the second characteristic humidity RD of the secondary dehumidification wheel is 50%RH, and the wheel humidity threshold ZSD is 70%RH; because the first characteristic humidity YD and the second characteristic humidity RD are not greater than the wheel humidity threshold ZSD, based on the formula: ZS1=ZR×μ×exp(-|((γ1×YD+γ2×RD)-(LT×ZSD)) / (LT×ZSD)|)=10×0.9×exp(-|((0.6×60%RH+0.4×50%RH)-(0.8×70%RH)) / (0.8×70%RH)|)=9 rpm, and the initial dehumidification wheel speed ZS1=9 rpm is obtained; wherein, in this embodiment, the value of the proportional adjustment coefficient γ1 is 0.6, the value of the proportional adjustment coefficient γ2 is 0.4, the value of the proportional adjustment coefficient LT is 0.8, and the value of the amplitude adjustment coefficient μ is 0.9; the middle value ZR of the suitable speed range is 10 rpm.

[0040] In this application, the dry air passing through the dehumidification zone of the secondary dehumidification wheel is divided into dry air 1 and dry air 2 based on the steering device, including: The manually set dry air flow rate of the second air is extracted from the database, and based on the dry air flow rate of the second air, the dry air in the dehumidification zone of the secondary dehumidification wheel is diverted into dry air one and dry air two through a steering device; the dry air two is transported to the room, and the dry air one is transported to the secondary heating device; wherein, the secondary heating device is a device for drying the secondary dehumidification wheel.

[0041] It should be noted that based on the size of the dry air two flow rate, the dry air in the dehumidification zone of the secondary dehumidification wheel is diverted into dry air one and dry air two through a steering device. This means that the remaining dry air is diverted into dry air one while ensuring that the dry air two flow rate meets the set value.

[0042] See also Figure 3 In this application, the heating power of the secondary heating device is dynamically adjusted based on the dry wind information, the second characteristic humidity and the rotation speed of the secondary dehumidification wheel, including: E1: Get the flow rate Q1 of dry air one in the dry air one information, and determine whether the flow rate Q1 is less than the dry air flow threshold; if yes, adjust the heating power of the secondary heating device to the maximum value of the power suitable range; if no, get the humidity SD1 of dry air one in the dry air one information, and get the required drying factor ZY1 of dry air one based on the formula ZY1=σ1×ln((Q1×SD1-BQ1×BSD1) / (BQ1×BSD1)+1), and jump to E2; wherein, the dry air flow threshold is obtained through experience, and the power suitable range is obtained through manual setting; σ1 is the amplitude adjustment coefficient of the ln() function, and the value range of σ1 is (0,2); BQ1 is the standard flow rate of dry air one set by experience, and BSD1 is the standard humidity of dry air one set by experience; the dry air one information includes the flow rate and humidity of dry air one; E2: extract the second characteristic humidity RD of the secondary dehumidification wheel, and determine whether the second characteristic humidity RD is greater than the wheel humidity threshold ZSD; if yes, control the heating power of the secondary heating device to adjust to the maximum value of the appropriate power range; if no, jump to E3; E3: Extract the speed ZS2 of the secondary dehumidification wheel and the middle value ZR of the suitable speed range, and obtain the heating power RP2 of the secondary heating device based on the formula RP2=(σ2×ln(θ1×RD / (LT×ZSD)+θ2×ZR / ZS2+1)+ZY1)×BP, and adjust the secondary heating device according to the heating power RP2; wherein BP is the manually set standard heating power, σ2 is the amplitude adjustment coefficient of the ln() function, and the value range of σ2 is (0,2); θ1 and θ2 are both proportional adjustment coefficients greater than 0, and θ1+θ2=1.

[0043] It is worth noting that if you want to analyze the effect of drying an area, you can analyze it from the flow rate of dry air and the heat carried; the flow rate can be indirectly understood as wind speed. When other conditions are fixed, the higher the wind speed, the better the drying effect of the area. Similarly, the heat carried can be indirectly understood as dry air temperature. When other conditions are fixed, the higher the dry air temperature, the better the drying effect of the area. When the dry wind has a certain amount of heat after passing through the secondary heating device, this heat is combined with the wind speed to dry the secondary dehumidification wheel. In the process of the dry wind passing through the secondary heating device to heat the dry wind, the present invention takes into account the situation where the flow rate of the dry wind and the heat carried have a superimposed drying effect. For example, when the conditions in the area to be dried remain unchanged, when the flow rate of the dry wind and the heat carried become higher, it may cause the drying effect to be "one plus one is greater than two". At this time, the hygroscopic material of the secondary dehumidification wheel may be burned. Because the dry wind is formed at the turning device, this causes the dry wind to have flow first and then have heat after passing through the secondary heating device. Therefore, when the present invention adjusts the comprehensive drying effect between the flow rate of the dry wind and the heat carried, the heat obtained by heating the secondary heating device is calculated according to the change in the flow rate of the dry wind. In this way, the drying effect on the secondary dehumidification wheel will not exceed the safety range, thereby reducing the internal loss and fire risk of the dehumidifier equipment.

[0044] It is worth noting that, because the function of dry air 1 is to dry the secondary dehumidification wheel, the heating of dry air 1 by the secondary heating device needs to take into account not only the flow rate of the heated dry air but also the humidity of the dry air. The humidity of dry air 1 will also affect the heating effect. The present invention conducts a comprehensive analysis of the flow rate and humidity of dry air 1 to obtain a characteristic factor that can indirectly express the amount of heating required by the dry air 1 itself, which is used for subsequent adjustment of the heating power of the secondary heating device.

[0045] It is worth noting that the drying and dehumidification wheel can control the dehumidification effect by adjusting the rotational speed of the dehumidification wheel or the heating power of the heating device, but when the two are adjusted at the same time, it may cause superimposed changes in the heating effect. For example, if the two are increased at the same time, the heating effect caused is greater than the required effect, which may cause the burning of the wheel material or energy loss, or if the two are reduced at the same time, the heating effect caused is less than the required effect, which may cause the drying of the dehumidification wheel to fail to meet the requirements, resulting in a reduction in the dehumidification effect of the room. When heating the dehumidification wheel, the present invention takes into account the situation that the rotational speed of the dehumidification wheel and the heating of the heating device have a superimposed drying effect. Therefore, the present invention conducts a linkage analysis on the rotational speed of the dehumidification wheel and the heating power of the heating device, and dynamically adjusts the heating power of the heating device according to the rotational speed of the dehumidification wheel, so that the superimposed effect caused by the rotational speed of the dehumidification wheel and the heating of the heating device and the required drying effect reach a delicate balance, thereby reducing the heating energy consumption while improving the accuracy of the heating effect.

[0046] It should be noted that the flow rate of dry air one can be detected by an air flow detector, and can also be calculated by splitting the dry air in the dehumidification zone of the secondary dehumidification wheel into dry air one and dry air two; the humidity of dry air one is detected by a humidity monitor.

[0047] In this embodiment, if the flow rate Q1 of the dry wind 1 is 600 cubic meters / hour, the humidity SD1 of the dry wind 1 is 40%RH, and the flow rate Q1 is not less than the dry wind flow rate threshold, the humidity SD1 of the dry wind 1 is obtained, and the required drying factor ZY1 of the dry wind 1 is obtained based on the formula ZY1=σ1×ln((Q1×SD1-BQ1×BSD1) / (BQ1×BSD1)+1)=1×ln((600×40%RH-700×30%RH) / (700×30%RH)+1)=0.134; wherein, in this embodiment, the value of the amplitude adjustment coefficient σ1 is 1, the standard flow rate BQ1 of the dry wind 1 is 700 cubic meters / hour, the standard humidity BSD1 of the dry wind 1 is 30%RH, and the dry wind flow rate threshold is 400 cubic meters / hour; The second characteristic humidity RD = 50%RH of the secondary dehumidification wheel is extracted. Since the second characteristic humidity RD is not greater than the wheel humidity threshold ZSD = 70%RH, the speed ZS2 = 9.1 of the secondary dehumidification wheel is extracted, and the middle value of the suitable speed range ZR = 10 is extracted. Based on the formula RP2 = (σ2 × ln (θ1 × RD / (LT × ZSD) + θ2 × ZR / ZS2 + 1) + ZY1) × BP = (0.98 × ln (0.6 × 50%RH / (0.8 × 7 0%RH)+0.4×10 / 9.1+1)+0.134)×1000=801W, and the heating power RP2=801W of the secondary heating device is obtained. The secondary heating device is adjusted according to the heating power RP2=801W; wherein, in this embodiment, the amplitude adjustment coefficient σ2 is 0.98, the proportional adjustment coefficient LT is 0.8, the proportional adjustment coefficient θ1 is 0.6, the proportional adjustment coefficient θ2 is 0.4, and the standard heating power BP=1000W.

[0048] In the present application, the heating power of the preliminary heating device is adjusted based on the three pieces of dry wind information and the rotation speed of the preliminary dehumidification wheel, including: F1: Get the flow rate Q3 of dry air three in the dry air three information, and determine whether the flow rate Q3 is less than the dry air flow threshold; if yes, adjust the heating power of the preliminary heating device to the maximum value of the appropriate power range; if no, get the humidity SD3 of dry air three in the dry air three information, and get the required drying factor ZY3 of dry air three based on the formula ZY3=σ3×ln((Q3×SD3-BQ3×BSD3) / (BQ3×BSD3)+1), and jump to F2; where σ3 is the amplitude adjustment coefficient of the ln() function, and the value range of σ3 is (0,2); BQ3 is the standard flow rate of dry air three set by experience, and BSD3 is the standard humidity of dry air three set by experience; the dry air three information includes the flow rate and humidity of dry air three; F2: Extract the speed ZS1 of the preliminary heating device and the middle value ZR of the suitable speed range, obtain the heating power RP1 of the preliminary heating device based on the formula RP1=(σ4×ln(θ3×ZR / ZS1+1)+ZY3)×BP, and adjust the preliminary heating device according to the heating power RP1; wherein, σ4 is the amplitude adjustment coefficient of the ln() function, and the value range of σ4 is (0,2); θ3 is the manually set proportional adjustment coefficient, and the value range of θ3 is (0,1].

[0049] It should be noted that when analyzing the heating power of the preliminary dehumidification wheel, the first characteristic humidity YD of the preliminary dehumidification wheel is not directly substituted into the formula for calculation. This is because the present invention has taken the first characteristic humidity YD into consideration when calculating the rotational speed of the preliminary dehumidification wheel. At this time, if the first characteristic humidity YD is substituted into the formula for calculation when analyzing the heating power of the preliminary dehumidification wheel, the first characteristic humidity YD will not only directly cause a change in the rotational speed of the preliminary dehumidification wheel, but also directly cause a change in the heating power of the preliminary heating device. This will cause the first characteristic humidity YD to bring two drying effects, resulting in errors caused by repeated considerations.

[0050] In this embodiment, the flow rate Q3 of dry air three is 506 cubic meters / hour. Since the flow rate Q3 is not less than the dry air flow threshold, the humidity SD3 of dry air three is obtained to be 25%RH. Based on the formula ZY3=σ3×ln((Q3×SD3-BQ3×BSD3) / (BQ3×BSD3)+1)=1×ln((506×25%RH-600×20%RH) / (600×20%RH)+1)=0.052, the required drying factor ZY3 of dry air three is obtained to be 0.052; wherein, in this embodiment, the amplitude adjustment coefficient σ3 is taken as 1, the standard flow rate BQ3 of dry air three is taken as 600 cubic meters / hour, and the humidity of dry air three is The standard humidity BSD3 = 20% RH; the rotation speed ZS1 = 9 rpm of the preliminary heating device and the middle value of the suitable rotation speed range ZR = 10 rpm are extracted; based on the formula RP1 = (σ4 × ln (θ3 × ZR / ZS1 + 1) + ZY3) × BP = (0.96 × ln (1 × 10 / 9 + 1) + 0.052) × 1000 = 769 W, the heating power RP1 = 769 W of the preliminary heating device is obtained; the preliminary heating device is adjusted according to the heating power RP1 = 769 W; wherein, in this embodiment, the amplitude adjustment coefficient σ4 is taken as 0.96, the proportional adjustment coefficient θ3 is taken as 1, and the standard heating power BP = 1000 W.

[0051] In this application, the indoor air and the outdoor air in the dehumidification zone of the preliminary dehumidification wheel are aggregated and cooled based on the aggregation device, including: The air obtained by polymerizing the indoor air and the outdoor air in the dehumidification zone of the preliminary dehumidification wheel by the polymerization device is marked as polymerized air, and the polymerized air is cooled to an expected temperature by a cooling surface cooler in the polymerization device; wherein the expected temperature is obtained by manual setting.

[0052] It should be noted that in a rotary dehumidifier, the main function of cooling the air is to promote the condensation of water vapor in the air by lowering the air temperature, thereby improving the dehumidification efficiency.

[0053] A second aspect of the present invention provides an adaptive control method for a rotary dehumidifier, comprising the following steps: S1: Obtain target data through distributed monitoring equipment, and analyze the target data to obtain characteristic values ​​of the target data; S2: dynamically adjusting the speed of the secondary dehumidification wheel based on the indoor characteristic humidity, and dynamically adjusting the speed of the primary dehumidification wheel based on the first characteristic humidity and the second characteristic humidity; S3: Based on the steering device, the dry air passing through the dehumidification zone of the secondary dehumidification wheel is diverted into dry air one and dry air two; based on the dry air one information, the second characteristic humidity and the rotation speed of the secondary dehumidification wheel, the heating power of the secondary heating device is dynamically adjusted; based on the dry air three information and the rotation speed of the preliminary dehumidification wheel, the heating power of the preliminary heating device is adjusted; based on the aggregation device, the indoor air and the outdoor air passing through the dehumidification zone of the preliminary dehumidification wheel are aggregated and cooled.

[0054] Part of the data in the above formula is calculated by removing the dimension and taking its numerical value. The formula is a formula closest to the actual situation obtained by software simulation of a large amount of collected data; the preset parameters and preset thresholds in the formula are set by technical personnel in this field according to actual conditions or obtained through simulation of a large amount of data.

[0055] Working principle of the present invention: The target data is obtained through distributed monitoring equipment, and the target data is analyzed to obtain the characteristic value of the target data; the speed of the secondary dehumidification wheel is dynamically adjusted based on the indoor characteristic humidity. In this step, the speed of the secondary dehumidification wheel is dynamically adjusted according to the indoor characteristic humidity. This can make the dehumidification performance of the rotary dehumidifier change with the change of humidity in the environment, avoiding high-performance operation in a low-humidity environment; the speed of the preliminary dehumidification wheel is dynamically adjusted based on the first characteristic humidity and the second characteristic humidity; the dry air passing through the dehumidification zone of the secondary dehumidification wheel is divided into dry air one and dry air two based on the steering device; the heating power of the secondary heating device is dynamically adjusted based on the dry air one information, the second characteristic humidity and the speed of the secondary dehumidification wheel, and the heating power of the preliminary heating device is adjusted based on the dry air three information and the speed of the preliminary dehumidification wheel. This step can achieve a delicate balance between the superposition effect caused by the speed of the dehumidification wheel and the heating of the heating device and the required drying effect, thereby reducing the heating energy consumption while improving the accuracy of the heating effect; the indoor air and the outdoor air passing through the dehumidification zone of the preliminary dehumidification wheel are aggregated and cooled based on the aggregation device.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
