Description

Technical Field

[0001] The present application relates to the field of dehumidifiers, and in particular to a control method, device and storage medium for a rotary dehumidifier. Background Art

[0002] Rotary dehumidifier is an important branch of air conditioning field and a typical representative of heating dehumidification. At present, for dual-rotor dehumidifier, in order to save the energy consumption of the rotary dehumidifier, a heating coil is usually randomly selected from the front regeneration heating coil and the rear regeneration heating coil for valve opening control and temperature control. This control method is very arbitrary and has a control blind spot, resulting in insignificant energy saving of the rotary dehumidifier.

[0003] The above statements are only used to provide background information related to the present application and do not necessarily constitute prior art. Summary of the invention

[0005] In a first aspect, the present application provides a control method for a rotary dehumidifier, comprising:

[0006] Acquiring a first environmental parameter for characterizing the dew point of mixed air, and acquiring a second environmental parameter for characterizing the dew point of supply air, wherein the mixed air is a gas obtained by mixing the air flowing out of the front wheel of the rotary dehumidifier and the supply air, and the supply air is the air delivered by the rotary dehumidifier to the space where the rotary dehumidifier is applied;

[0007] The valve opening of the front regenerative heating coil of the rotary dehumidifier is adjusted based on the first environmental parameter, and the valve opening of the rear regenerative heating coil of the rotary dehumidifier is adjusted based on the second environmental parameter.

[0008] The solution of the present application realizes synchronous adjustment of the valve opening of the front regeneration coil and the rear regeneration coil, improves the accuracy of coil control, realizes the smooth operation of the front regeneration coil and the rear regeneration coil, reduces fluctuations, and thus reduces the efficiency of the rotary dehumidifier. At the same time, based on the above-mentioned precise control of the valve opening of the front regeneration coil and the rear regeneration coil, the setting of the temperature range of the front regeneration coil and the rear regeneration coil is cancelled, and the temperature of the front regeneration coil and the rear regeneration coil is controlled during the valve opening control process, so that the temperature of the front regeneration coil and the rear regeneration coil automatically changes with external factors such as different regions and different seasons, and finally realizes automatic adjustment of the coil temperature.

[0009] In some embodiments, obtaining a first environmental parameter for characterizing a dew point of mixed air includes:

[0010] Acquire a plurality of environmental parameters for characterizing the dew point of the mixed air within a preset historical time period;

[0011] Calculating parameter means of the multiple environmental parameters;

[0012] The parameter mean is used as the first environmental parameter.

[0013] Using the parameter mean of multiple environmental parameters as the first environmental parameter helps the rear wheel to maintain stable operation, and further helps to save energy consumption of the rotary dehumidifier.

[0014] In some embodiments, obtaining a second environmental parameter for characterizing a dew point of supply air includes:

[0015] Collecting space environment parameters and detecting air supply environment parameters, wherein the space environment parameters are used to characterize the dew point of the air in the space, and the air supply environment parameters are used to characterize the dew point of the air flowing out of the rear air blower of the rotary dehumidifier;

[0016] The second environmental parameter is determined based on the space environmental parameter, the air supply environmental parameter and the preset environmental parameter.

[0017] Determining the second environmental parameter based on the space environmental parameter, the air supply environmental parameter and the preset environmental parameter helps to maintain the stability of the dew point of the space air.

[0018] In some embodiments, determining the second environmental parameter based on the space environmental parameter, the air supply environmental parameter and the preset environmental parameter includes:

[0024] Inputting the current temperature into the objective function relationship to obtain the current operating frequency of the rear supply fan;

[0025] The rear supply fan is controlled to operate at the current operating frequency.

[0026] An objective function relationship is set up to reflect the changing law of the space temperature as the operating frequency of the rear-supply fan of the rotary dehumidifier changes. By using this function relationship and combining it with the current temperature of the space, the current operating frequency adapted to the current temperature of the space can be calculated, and the rear-supply fan can be controlled to operate at the current operating frequency, thereby realizing the variable air volume operation of the rear-supply fan, which helps to save the energy consumption of the rotary dehumidifier.

[0027] In some embodiments, obtaining the objective function relationship includes:

[0028] collecting a first space temperature of the space when the rear supply fan operates at the lowest operating frequency, and collecting a second space temperature of the space when the rear supply fan operates at the highest operating frequency;

[0029] The objective function relationship is obtained based on the lowest operating frequency, the first space temperature, the highest operating frequency, and the second space temperature.

[0030] Based on the first space temperature collected when the rear-supply fan runs at the lowest operating frequency and the second space temperature collected when the rear-supply fan runs at the highest operating frequency, the objective function relationship is obtained. The scheme is simple and easy to implement, and the lowest operating frequency and the highest operating frequency are the frequencies allowed for the normal operation of the rear-supply fan, so the rear-supply fan will not be damaged.

[0031] In some embodiments, obtaining the objective function relationship based on the minimum operating frequency, the first space temperature, the maximum operating frequency, and the second space temperature includes:

[0032] Calculating a target linear function relationship based on the minimum operating frequency, the first space temperature, the maximum operating frequency, and the second space temperature;

[0033] Based on the operating parameters of the rotary dehumidifier, the slope of the target linear function relationship is adjusted to obtain the target function relationship.

[0034] After obtaining the target linear function relationship, the slope of the target linear function relationship is adjusted with reference to the operating parameters of the rotary dehumidifier, so that the target function relationship obtained is more consistent with the actual operation of the rotary dehumidifier and has a relatively high actual reference value.

[0054] Rotary dehumidifier is an important branch in the field of air conditioning and is a typical representative of heating dehumidification. The core component of the rotary dehumidifier is a dehumidification wheel, on which a desiccant is arranged, including a regeneration area and a treatment area. During dehumidification, when the indoor humid air (treatment air) enters the treatment area of ​​the wheel after being frozen and dehumidified by the surface cooler, the water vapor of the humid air is adsorbed by the desiccant of the dehumidification wheel, and the dry air after dehumidification is sent to the room to complete the dehumidification process; then the dehumidification wheel slowly rotates so that the desiccant adsorbing water vapor enters the regeneration area; the regeneration area is connected to the regeneration heating coil, and the high-temperature gas (regeneration air) in the regeneration heating coil dries the desiccant in the regeneration area, so that the water vapor in the desiccant is separated from the desiccant and discharged outdoors, thereby restoring the dehumidification function of the dehumidification wheel and completing the regeneration process. With the continuous rotation of the dehumidification wheel, the above-mentioned dehumidification process and regeneration process are repeated, thereby ensuring the continuous and stable dehumidification state of the dehumidifier.

[0055] The double-rotor dehumidifier has two rotors, namely the front rotor and the rear rotor. During the operation of the double-rotor dehumidifier, the fresh air flows into the front rotor after passing through the front surface cooler, and the first-stage dehumidification is completed at the front rotor. The air after the first-stage dehumidification flows into the rear rotor through the front supply fan and the middle surface cooler, and the second-stage dehumidification is completed at the rear rotor. The air after the second-stage dehumidification passes through the rear surface cooler and the rear supply fan and flows into the room.

[0056] In order to achieve the regeneration of the desiccant in the front wheel regeneration zone and the rear wheel regeneration zone, the dual wheel dehumidifier also has a front regeneration heating coil connected to the front wheel and a rear regeneration heating coil connected to the rear wheel. The front regeneration heating coil passes through the regeneration zone of the front wheel, and the high-temperature gas in the front regeneration heating coil dries the desiccant in the regeneration zone, so that the water vapor in the desiccant is separated from the desiccant, thereby restoring the desiccant function of the front wheel and completing the regeneration process. The rear regeneration heating coil passes through the regeneration zone of the rear wheel, and the high-temperature gas in the rear regeneration heating coil dries the desiccant in the regeneration zone, so that the water vapor in the desiccant is separated from the desiccant, thereby restoring the desiccant function of the rear wheel and completing the regeneration process.

[0057] On the basis of meeting the indoor dehumidification requirements, in order to reduce the energy consumption of the double-rotor dehumidifier, the valve opening control and temperature control are usually performed in the front regenerative heating coil or the rear regenerative heating coil. Specifically, the valve opening of the front regenerative heating coil or the rear regenerative heating coil is controlled within the set temperature range. By adjusting the valve opening in the front regenerative heating coil or the rear regenerative heating coil, the flow rate of the high-temperature gas flowing in the front regenerative heating coil or the rear regenerative heating coil can be changed, thereby changing the regeneration efficiency of the regeneration zone of the front rotor or the regeneration zone of the rear rotor, achieving the effect of saving energy consumption.

[0058] In the related art, a regenerative heating coil is randomly selected from the front regenerative heating coil or the rear regenerative heating coil for valve opening control and temperature control. And when performing temperature control, it is necessary to manually set the temperature range of the front regenerative heating coil or the rear regenerative heating coil according to the season. There are often empirical errors in the artificial setting of the temperature range, and this empirical error will eventually affect the energy saving of the dual-rotor dehumidifier. In addition, the control method of randomly selecting a regenerative heating coil from the front regenerative heating coil and the rear regenerative heating coil for control is very arbitrary, and there are control blind spots, which will also lead to unclear energy saving of the rotary dehumidifier.

[0059] In order to alleviate the problems existing in the related art, the embodiment of the present application provides a control method, device and storage medium for a rotary dehumidifier. The method includes obtaining a first environmental parameter for characterizing the dew point of mixed air, and obtaining a second environmental parameter for characterizing the dew point of supply air, wherein the mixed air is the gas after the air flowing out of the front wheel of the rotary dehumidifier is mixed with the supply air, and the supply air is the air delivered by the rotary dehumidifier to the space where the rotary dehumidifier is applied; adjusting the valve opening of the front regenerative heating coil of the rotary dehumidifier based on the first environmental parameter, and adjusting the valve opening of the rear regenerative heating coil of the rotary dehumidifier based on the second environmental parameter. The scheme of the present application is adopted to realize the synchronous adjustment of the valve opening of the front regenerative coil and the rear regenerative coil, improve the accuracy of the coil control, realize the smooth operation of the front regenerative coil and the rear regenerative coil, reduce fluctuations, and thus reduce the efficiency of the rotary dehumidifier. At the same time, based on the above-mentioned precise control of the valve opening of the front regeneration coil and the rear regeneration coil, the setting of the temperature range of the front regeneration coil and the rear regeneration coil is cancelled, and the temperature of the front regeneration coil and the rear regeneration coil is controlled during the valve opening control process, so that the temperature of the front regeneration coil and the rear regeneration coil automatically changes with external factors such as different regions and seasons, and finally the coil temperature is automatically adjusted.

[0060] The control method of the rotary dehumidifier in the embodiment of the present application can be applied to an electronic device, which may be a terminal or a server. The terminal includes but is not limited to a rotary dehumidifier, a computer device communicating with the rotary dehumidifier, etc., and the server includes but is not limited to a cloud server, a server cluster, etc.

[0061] like Figure 1 As shown, the control method of the rotary dehumidifier may include the following steps:

[0062] Step 101, obtaining a first environmental parameter for characterizing the dew point of mixed air, and obtaining a second environmental parameter for characterizing the dew point of supply air, wherein the mixed air is a gas obtained by mixing the air flowing out of the front wheel of the rotary dehumidifier and the supply air, and the supply air is the air delivered by the rotary dehumidifier to the space where the rotary dehumidifier is applied;

[0063] Step 102: adjusting the valve opening of the front regenerative heating coil of the rotary dehumidifier based on the first environmental parameter, and adjusting the valve opening of the rear regenerative heating coil of the rotary dehumidifier based on the second environmental parameter.

[0064] In this embodiment, the first environmental parameter includes but is not limited to a temperature parameter, a relative humidity parameter or a moisture content parameter. Wherein, the dew point refers to the temperature to which the gaseous water contained in the air needs to be reduced to reach saturation and condense into liquid water under a fixed air pressure. It should be understood that after obtaining the first environmental parameter, the first environmental parameter can be directly converted to obtain the dew point of the air. Accordingly, the second environmental parameter includes but is not limited to a temperature parameter, a relative humidity parameter or a moisture content parameter. It should be understood that the first environmental parameter and the second environmental parameter can be parameters of the same type or parameters of different types.

[0065] In actual applications, the humidity of the supply air is usually low. Therefore, in order to improve the dehumidification efficiency of the rotary dehumidifier, the supply air will be transported as return air to the mixing point between the front rotor and the front supply fan, and the air flowing out of the front rotor and the return air will be mixed at the mixing point, which will help reduce the dehumidification amount of the rear rotor and obtain air that meets the indoor humidity requirements as soon as possible. Therefore, the first environmental parameter at the mixing point can more accurately reflect the dehumidification effect of the front rotor, and using the first environmental parameter to adjust the valve opening of the front regenerative heating coil will help improve the accuracy of the control of the front regenerative heating coil.

[0066] In this embodiment, the first environmental parameter and the second environmental parameter can be determined based on the target humidity of the space where the rotary dehumidifier is applied, the dehumidification efficiency of the front wheel, and the dehumidification efficiency of the rear wheel. Among them, the target humidity is used to indicate the desired humidity of the space. It should be understood that when the humidity at the mixing point collected is quite different from the target humidity, even if the rear wheel operates at the highest efficiency, it may still not be possible to make the humidity of the space reach the target humidity. Therefore, in this case, it is expected that the front wheel has a better dehumidification efficiency and the mixed air at the mixing point has a lower dew point. On the contrary, when the humidity at the mixing point collected is not much different from the target humidity, further dehumidification of the rear wheel can make the humidity of the air delivered to the space reach the target humidity. In this case, in order to save energy consumption, it can be set so that the mixed air at the mixing point has a suitable dew point, and the supply air has a suitable dew point at the same time.

[0067] In an example, the first environmental parameter is represented by the first humidity, and the second environmental parameter is represented by the second humidity. When the first humidity and the second humidity are determined based on the target humidity, the dehumidification efficiency of the front wheel, and the dehumidification efficiency of the rear wheel, the calculation formulas of the first humidity and the second humidity are as follows:

[0068] First humidity = dehumidification efficiency of the front wheel / (dehumidification efficiency of the front wheel + dehumidification efficiency of the rear wheel)

[0069] Second humidity = dehumidification efficiency of the rear wheel / (dehumidification efficiency of the front wheel + dehumidification efficiency of the rear wheel)

[0070] As an example, assuming the target humidity is 30%, the dehumidification efficiency of the front wheel is 20%, and the dehumidification efficiency of the rear wheel is 10%, then:

[0071] First humidity = 20% / (10%+20%)*30% = 20%

[0072] Second humidity = 10% / (10%+20%)*30% = 10%

[0073] It should be understood that the target humidity may be different in different regions and seasons.

[0074] It should be understood that in actual applications, the first environmental parameter and the second environmental parameter may also be empirical values, that is, values ​​set by the user according to actual experience or working conditions.

[0075] In this embodiment, the electronic device is pre-configured with a mapping relationship between environmental parameters and valve openings. Therefore, after obtaining the first environmental parameter and the second environmental parameter, the mapping relationship is queried using the first environmental parameter and the second environmental parameter, respectively, to obtain a first valve opening corresponding to the first environmental parameter and a second valve opening corresponding to the second environmental parameter. In practical applications, when adjusting the valve opening of the front regenerative heating coil or the valve opening of the rear regenerative heating coil, PID control can be used to improve control accuracy.

[0076] In the technical solution provided by this embodiment, a first environmental parameter characterizing the dew point of the mixed air and a second environmental parameter characterizing the dew point of the supply air are obtained, and the first environmental parameter is used to adjust the opening of the front regeneration heating coil, and the second environmental parameter is used to adjust the opening of the rear regeneration heating coil. The solution of this application is used to achieve synchronous adjustment of the valve opening of the front regeneration coil and the rear regeneration coil, improve the accuracy of coil control, achieve smooth operation of the front regeneration coil and the rear regeneration coil, reduce fluctuations, and thus reduce the efficiency of the rotary dehumidifier. At the same time, based on the above-mentioned precise control of the valve opening of the front regeneration coil and the rear regeneration coil, the setting of the temperature range of the front regeneration coil and the rear regeneration coil is cancelled, and the temperature of the front regeneration coil and the rear regeneration coil is controlled during the valve opening control process, so that the temperature of the front regeneration coil and the rear regeneration coil automatically changes with external factors such as different regions and seasons, and finally the coil temperature is automatically adjusted.

[0077] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0078] In one or more embodiments of the present application, obtaining a first environmental parameter for characterizing the dew point of the mixed air may include:

[0079] Acquire multiple environmental parameters for characterizing the dew point of mixed air within a preset historical time period;

[0080] Calculate parameter means of multiple environmental parameters;

[0081] The parameter mean is taken as the first environmental parameter.

[0082] In this embodiment, the preset historical time period includes but is not limited to historical time periods covering different seasons or different weather conditions. In the application, the historical time period can be set manually based on experience or according to working conditions. For example, the historical time period can be set to a whole year.

[0083] In applications, a sensor may be provided at the mixing point to collect environmental parameters representing the dew point of the mixed air at different time points within a preset historical time period.

[0084] It should be understood that the regeneration load of the front wheel comes from the fresh air and the return air. The state parameters of the fresh air are constantly changing over time, while the state parameters of the return air are basically unchanged. Therefore, the temperature and humidity of the regeneration load of the front wheel will change with time and seasons. When the first environmental parameter is set with the parameter mean of multiple environmental parameters, since the parameter mean of multiple environmental parameters is basically a certain value, the parameter mean is used as the first environmental parameter, so that the humidity content of the air processed by the rear wheel can be basically maintained at a constant value, which helps the rear wheel to maintain stable operation and further helps to save energy consumption of the rotary dehumidifier.

[0085] In the solution provided in this embodiment, the parameter average of multiple environmental parameters is used as the first environmental parameter, which helps the rear wheel to maintain stable operation and further helps to save energy consumption of the rotary dehumidifier.

[0086] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0087] In one or more embodiments of the present application, obtaining a second environmental parameter for characterizing the dew point of the supply air may include:

[0088] Collect space environment parameters and detect air supply environment parameters. The space environment parameters are used to characterize the dew point of the air in the space, and the air supply environment parameters are used to characterize the dew point of the air flowing out of the rear air blower of the rotary dehumidifier;

[0089] Based on the space environment parameters, the air supply environment parameters and the preset environment parameters, the second environment parameters are determined.

[0090] It should be understood that the space where the rotary dehumidifier is applied includes but is not limited to the workshop, laboratory, etc. of the factory. In the application, a temperature sensor or a humidity sensor can be arranged in the space to collect the space environment parameters. Similarly, a temperature sensor or a humidity sensor can be arranged at the air outlet of the rear blower to detect the air supply environment parameters.

[0091] In this embodiment, the preset environmental parameters are the environmental parameters of the air in the space desired by the user. The preset environmental parameters can be set by the user according to actual needs. In practical applications, an environmental parameter can be randomly selected from the space environmental parameters, the air supply environmental parameters and the preset environmental parameters as the second environmental parameter. Of course, the space environmental parameters, the air supply environmental parameters and the preset environmental parameters can also be weighted to obtain the second environmental parameter. In the weighted calculation process, the weights of the space environmental parameters, the air supply environmental parameters and the preset environmental parameters can be set manually based on experience.

[0092] It should be understood that the mapping relationship between the space environment parameter, the air supply environment parameter and the preset environment parameter and the valve opening of the post-regeneration heating coil can be set in advance, so that when a random environment parameter is randomly selected from the space environment parameter, the air supply environment parameter and the preset environment parameter as the second environment parameter, the mapping relationship matching the randomly selected environment parameter can be found for query. The environment parameters in the mapping relationship in the application can be expressed as intervals, that is, in the mapping relationship, one valve opening corresponds to one environment parameter interval, which helps to simplify the setting of the mapping relationship and reduce the amount of data processing.

[0093] Similarly, a mapping relationship between weighted environmental parameters and valve openings can also be set so that a weighted operation is performed on the space environmental parameters, the air supply environmental parameters, and the preset environmental parameters, and when a second environmental parameter is obtained, the valve opening corresponding to the second environmental parameter can be found. In order to simplify the setting of the mapping relationship, in this case, the environmental parameters in the mapping relationship can also be expressed as intervals.

[0094] In the solution provided in this embodiment, the second environmental parameter is determined based on the space environmental parameter, the air supply environmental parameter and the preset environmental parameter, which helps to maintain the stability of the dew point of the air in the space.

[0095] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0096] In one or more embodiments of the present application, determining the second environmental parameter based on the space environmental parameter, the air supply environmental parameter and the preset environmental parameter may include:

[0097] From the space environment parameters, air supply environment parameters and preset environment parameters, select the environment parameter with the largest value;

[0098] The environment parameter with the largest value is taken as the second environment parameter.

[0099] Taking the dew point temperature as an example to represent the space environment parameters, air supply environment parameters and preset environment parameters, assuming that the preset dew point temperature is -30°C, the space dew point temperature is -29°C, and the air supply dew point temperature is -32°C, then the dew point temperature with the largest value is -29°C, so the dew point temperature represented by the second environment parameter is -29°C.

[0100] In the technical solution provided in this embodiment, the environmental parameter with the largest parameter value is selected from the space environmental parameters, the air supply environmental parameters and the preset environmental parameters, that is, the environmental parameter representing the most undesirable dew point, which helps to make the three environmental parameters meet the space's requirements for humidity generation.

[0101] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0102] In one or more embodiments of the present application, the method may further include:

[0103] Obtaining the objective function relationship and the current temperature of the acquisition space, the objective function relationship is used to reflect the change law of the space temperature of the space with the change of the operating frequency of the rear supply fan of the rotary dehumidifier;

[0104] Input the current temperature into the objective function relationship to obtain the current operating frequency of the rear supply fan;

[0105] Control the rear supply fan to run at the current operating frequency.

[0106] In this embodiment, the objective function relationship may be a linear function relationship in which the space temperature changes with the operating frequency of the blower. In the linear function relationship, the slope of the linear function relationship may be set manually according to needs or according to the operating conditions of the rotary dehumidifier.

[0107] In the related art, the operating frequency of the rear-supply fan of the rotary dehumidifier supports adjustable operation, but the rear-supply fan has no automatic frequency conversion function, and will not change the operating frequency as the temperature and humidity in the workshop change, and the variable air volume operation of the rear-supply fan cannot be realized. In the technical solution provided in this embodiment, an objective function relationship is set to reflect the change law of the space temperature of the space as the operating frequency of the rear-supply fan of the rotary dehumidifier changes. By using this function relationship and combining it with the current temperature of the space, the current operating frequency adapted to the current temperature of the space can be calculated, and the rear-supply fan can be controlled to operate at the current operating frequency, thus realizing the variable air volume operation of the rear-supply fan, which helps to save the energy consumption of the rotary dehumidifier.

[0108] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0109] In one or more embodiments of the present application, obtaining the objective function relationship includes:

[0110] A first space temperature of the space when the rear air supply fan is running at the lowest operating frequency is collected, and a second space temperature of the space when the rear air supply fan is running at the highest operating frequency is collected;

[0111] Based on the lowest operating frequency, the first space temperature, the highest operating frequency, and the second space temperature, an objective function relationship is obtained.

[0112] It should be understood that the minimum operating frequency and the maximum operating frequency of the rear-supply fan are marked in the working parameters of the rear-supply fan. In actual applications, the electronic device can obtain the minimum operating frequency and the maximum operating frequency of the rear-supply fan from the working parameters, and control the rear-supply fan to operate at the minimum operating frequency and the maximum operating frequency for a period of time, so as to collect the first space temperature and the second space temperature.

[0113] In order to improve the accuracy of the first space temperature and the second space temperature, the first space temperature and the second space temperature can be the average of the space temperatures collected over a period of time. That is, the first space temperature is the average of all space temperatures collected when the rear supply fan runs at the lowest operating frequency for a period of time. Similarly, the second space temperature is the average of all space temperatures collected when the rear supply fan runs at the highest operating frequency for a period of time.

[0114] In this embodiment, the slope can be directly calculated based on the lowest operating frequency, the first space temperature, the highest operating frequency and the second space temperature, and a linear function relationship can be obtained based on the slope, so that the linear function relationship is used as the target function relationship.

[0115] Wherein, slope = (highest operating frequency - lowest operating frequency) / (second space temperature - first space temperature)

[0116] The linear function relationship can be: Y=KX; K is the slope.

[0117] In the solution provided in this embodiment, the objective function relationship is obtained based on the first space temperature collected when the rear-supply fan is running at the lowest operating frequency and the second space temperature collected when the rear-supply fan is running at the highest operating frequency. The solution is simple and easy to implement, and the lowest operating frequency and the highest operating frequency are the frequencies allowed for the normal operation of the rear-supply fan, so the rear-supply fan will not be damaged.

[0118] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0119] In one or more embodiments of the present application, obtaining the objective function relationship based on the lowest operating frequency, the first space temperature, the highest operating frequency, and the second space temperature may include:

[0120] Based on the lowest operating frequency, the first space temperature, the highest operating frequency, and the second space temperature, a target linear function relationship is calculated;

[0121] Based on the operating parameters of the rotary dehumidifier, the slope of the target linear function relationship is adjusted to obtain the target function relationship.

[0122] In this embodiment, the operating parameters of the rotary dehumidifier are used to reflect the energy consumption of the rotary dehumidifier. When the energy consumption reflected by the operating parameters exceeds the set energy consumption range, the slope of the target linear function relationship can be increased or decreased. When the energy consumption reflected by the operating parameters does not exceed the set energy consumption range, the slope of the target linear function relationship may not be adjusted. In this case, the target linear function relationship is the target function relationship.

[0123] It should be understood that energy consumption exceeding the set energy consumption interval includes energy consumption greater than the maximum value within the energy consumption interval or less than the minimum value within the energy consumption interval. Wherein, when the energy consumption is greater than the maximum value within the energy consumption interval, the slope of the target linear function relationship can be reduced. Where the energy consumption is less than the minimum value within the energy consumption interval, the slope of the target linear function relationship can be increased.

[0124] In the application, the operating parameters of the rotary dehumidifier can also be displayed to the user through the human-computer interaction interface supported by the electronic device, and the user can adjust the slope of the target linear function relationship based on experience or actual needs and referring to the operating parameters.

[0125] The technical solution provided in this embodiment, after obtaining the target linear function relationship, adjusts the slope of the target linear function relationship with reference to the operating parameters of the rotary dehumidifier, so that the target function relationship obtained is more in line with the actual operation of the rotary dehumidifier and has a relatively high actual reference value.

[0126] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0127] In view of the technical solutions given in the above embodiments, the present application scheme is fully described below with a specific embodiment. Taking the space where the rotary dehumidifier is applied as a workshop as an example, Figure 2 This is a specific implementation flow chart of a control method for a rotary dehumidifier shown in accordance with an exemplary embodiment of the present application, comprising the following steps:

[0128] Step 201, obtaining multiple dew point temperatures of the mixing point in the rotary dehumidifier in the previous year.

[0129] The previous year refers to the year before the current year. For example, if the current year is 2023, the previous year refers to 2022.

[0130] The multiple dew point temperatures include but are not limited to dew point temperatures collected on a daily, weekly, monthly or quarterly basis.

[0131] Step 202: Calculate the temperature average of multiple dew point temperatures.

[0132] It should be understood that if multiple dew point temperatures are collected per day, the temperature average refers to the sum of the multiple dew point temperatures divided by the total number of days collected. If multiple dew point temperatures are collected per week, the temperature average refers to the total number of weeks in which the sum of the multiple dew point temperatures falls. By analogy, the temperature average of dew point temperatures collected monthly or quarterly can be calculated.

[0133] Step 203: Determine the valve opening of the front regeneration coil based on the temperature mean, and adjust the steam valve of the front regeneration heating coil according to the valve opening.

[0134] The obtained temperature average value may be used to query the mapping relationship between the preset average value and the valve opening, so as to obtain the valve opening of the front regeneration coil.

[0135] Step 204: Obtain the workshop dew point temperature, supply air dew point temperature, and preset expected dew point temperature of the air in the workshop.

[0136] Step 205: Select the target dew point temperature with the largest value from the dew point temperature in the workshop, the supply air dew point temperature and the expected dew point temperature.

[0137] Step 206: Determine the valve opening of the rear regeneration coil based on the target dew point temperature.

[0138] It should be understood that this embodiment does not limit the execution order between steps 201 to 203 and steps 204 to 206, that is, steps 201 to 203 may be executed before steps 204 to 206, or after steps 204 to 206, and of course, may be executed synchronously.
