TECHNICAL FIELD

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

[0002] The rotary dehumidifier belongs to an important branch of the air conditioning field and is a typical representative of temperature-increasing dehumidification. At present, for a double-rotary dehumidifier, in order to save the energy consumption of the rotary dehumidifier, one of the front regenerative heating coil and the rear regenerative heating coil is randomly selected for valve opening degree control and temperature control. This control method is random and has a control blind area, resulting in that the energy consumption saving is not obvious.

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

[0004] In view of the above problems, the embodiments of the present application provide a control method and device of a rotary dehumidifier and a storage medium, which can alleviate the problem that the energy consumption saving is not obvious caused by randomly selecting one of the front regenerative heating coil and the rear regenerative heating coil for valve opening degree control and temperature control.

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

[0006] obtaining a first environmental parameter for representing the dew point of mixed air, and obtaining a second environmental parameter for representing the dew point of supply air, the mixed air being the gas after the air flowing out of the front rotary wheel of the rotary dehumidifier is mixed with the supply air, and the supply air being the air transported by the rotary dehumidifier to the space where the rotary dehumidifier is applied;

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

[0008] The present application realizes the synchronous adjustment of the valve opening degrees of the front regenerative coil and the rear regenerative coil, improves the precision of the coil control, realizes the stable operation of the front regenerative coil and the rear regenerative coil, reduces the fluctuation, and thus reduces the efficiency of the rotary dehumidifier. At the same time, based on the above precise control of the valve opening degrees of the front regenerative coil and the rear regenerative coil, the temperature range of the front regenerative coil and the rear regenerative coil is cancelled, the temperature control of the front regenerative coil and the rear regenerative coil is realized in the process of valve opening degree control, the temperature of the front regenerative coil and the rear regenerative coil automatically changes with different regions, different seasons and other external factors, and finally the automatic adjustment of the coil temperature is realized.

[0009] In some embodiments, the first environment parameter for representing the dew point of the mixed air is obtained, including:

[0010] a plurality of environment parameters for representing the dew point of the mixed air in a preset historical time period are obtained;

[0011] a parameter mean of the plurality of environment parameters is calculated;

[0012] the parameter mean is taken as the first environment parameter.

[0013] Taking the parameter mean of the plurality of environment parameters as the first environment parameter helps to keep the rear wheel stable operation, and further helps to save the energy consumption of the wheel dehumidifier.

[0014] In some embodiments, the second environment parameter for representing the dew point of the supply air is obtained, including:

[0015] the space environment parameter for representing the dew point of the air in the space and the supply environment parameter for representing the dew point of the air flowing out from the rear supply fan of the wheel dehumidifier are collected;

[0016] the second environment parameter is determined based on the space environment parameter, the supply environment parameter and a preset environment parameter.

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

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

[0019] selecting an environment parameter with the largest parameter value from the space environment parameter, the supply environment parameter and the preset environment parameter;

[0020] taking the environment parameter with the largest parameter value as the second environment parameter.

[0021] Selecting the environment parameter with the largest parameter value from the space environment parameter, the supply environment parameter and the preset environment parameter, i.e. the environment parameter with the least ideal dew point, helps to make the three environment parameters meet the space humidity generation requirement.

[0022] In some embodiments, further comprising:

[0023] obtaining a target function relationship and collecting the current temperature of the space, the target function relationship being used to reflect the change rule of the space temperature of the space with the change of the operating frequency of the rear supply fan of the wheel dehumidifier;

[0024] inputting the current temperature into the target function relationship to obtain a current operating frequency of the return air blower;

[0025] controlling the return air blower to operate at the current operating frequency.

[0026] The target function relationship reflecting the change rule of the space temperature of the space changing with the operating frequency of the return air blower of the rotary dehumidifier is set, and the current operating frequency adapted to the current temperature of the space can be calculated by using the function relationship in combination with the current temperature of the space, and the return air blower is controlled to operate at the current operating frequency, so that the variable air volume operation of the return air blower is realized, which is helpful to save the energy consumption of the rotary dehumidifier.

[0027] In some embodiments, obtaining the target function relationship comprises:

[0028] collecting a first space temperature of the space when the return air blower operates at a minimum operating frequency, and collecting a second space temperature of the space when the return air blower operates at a maximum operating frequency;

[0029] obtaining the target function relationship based on the minimum operating frequency, the first space temperature, the maximum operating frequency and the second space temperature.

[0030] The target function relationship is obtained based on the first space temperature collected when the return air blower operates at the minimum operating frequency and the second space temperature collected when the return air blower operates at the maximum operating frequency, the scheme is simple and easy to implement, and the minimum operating frequency and the maximum operating frequency are the frequencies allowed for normal operation of the return air blower, so the return air blower will not be damaged.

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

[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] adjusting a slope of the target linear function relationship based on an operating parameter of the rotary dehumidifier 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 parameter 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 relatively high actual reference value.

[0035] In a second aspect, the application provides a control device of a rotary dehumidifier, comprising:

[0036] an acquisition module, configured to acquire a first environment parameter for characterizing a dew point of mixed air, and acquire a second environment parameter for characterizing a dew point of supply air, the mixed air being air after the supply air is mixed with air outflowed from a front runner of the rotary dehumidifier, the supply air being air delivered by the rotary dehumidifier to a space where the rotary dehumidifier is applied;

The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs; the terms used herein are only for the purpose of describing specific embodiments of the present application, and are not intended to limit the present application; the terms "include" and "have" and any variations thereof in the specification and claims of the present application and the above description of drawings are intended to cover non-exclusive inclusion.

The appearance of this phrase in various places in the specification does not necessarily mean the same embodiment, nor is it an independent or alternative embodiment to other embodiments.

In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0054] The rotary dehumidifier belongs to an important branch of the air conditioning field and is a typical representative of the temperature-increasing dehumidification. The core component of the rotary dehumidifier is a dehumidification rotor, and a honeycomb-shaped desiccant is arranged on the dehumidification rotor, including a regeneration zone and a treatment zone. When dehumidifying, after the indoor humid air (treatment air) is cooled and dehumidified by a surface cooler, the humid air enters the treatment zone of the dehumidification rotor, and the water vapor of the humid air is adsorbed by the desiccant of the dehumidification rotor. The dry air after dehumidification is sent to the indoor to complete the dehumidification process. Then, the dehumidification rotor slowly rotates to make the desiccant adsorbing water vapor enter the regeneration zone. The regeneration zone is connected with a regeneration heating coil, and the high-temperature gas (regeneration air) in the regeneration heating coil dries the desiccant in the regeneration zone, so that the water vapor in the desiccant is separated from the desiccant and discharged to the outdoor, thereby the dehumidification rotor restores the dehumidification function to complete the regeneration process. With the continuous rotation of the dehumidification rotor, the above 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 a front rotor and a rear rotor. In the working process 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 air blower and the middle surface cooler, and the second-stage dehumidification is completed at the rear rotor. The air after the second-stage dehumidification flows into the indoor through the rear surface cooler and the rear air blower.

[0056] In order to realize the regeneration of the desiccant in the regeneration zone of the front rotor and the regeneration zone of the rear rotor, the double-rotor dehumidifier further has a front regeneration heating coil connected with the front rotor and a rear regeneration heating coil connected with the rear rotor. The front regeneration heating coil passes through the regeneration zone of the front rotor, 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 the front rotor restores the dehumidification function to complete the regeneration process. The rear regeneration heating coil passes through the regeneration zone of the rear rotor, 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 the rear rotor restores the dehumidification function to complete 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 degree control and temperature control are usually performed on the front regeneration heating coil or the rear regeneration heating coil. Specifically, the opening degree of the valve of the front regeneration heating coil or the rear regeneration heating coil is controlled within a set temperature range. By adjusting the opening degree of the valve in the front regeneration heating coil or the rear regeneration heating coil, the flow rate of the high-temperature gas flowing in the front regeneration heating coil or the rear regeneration 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, and achieving the effect of saving energy consumption.

[0058] In the related art, one of the front regenerative heating coil or the rear regenerative heating coil is randomly selected for valve opening degree control and temperature control. When temperature control is performed, the temperature range of the front regenerative heating coil or the rear regenerative heating coil needs to be manually set according to the season. The manual setting of the temperature range often has an experience error, which ultimately affects the energy saving of the double-rotor dehumidifier. In addition, the control mode of randomly selecting one of the front regenerative heating coil and the rear regenerative heating coil for control has great randomness and exists a control blind area, which also leads to an insignificant energy saving of the rotor dehumidifier.

[0059] To alleviate the problems in the related art, the embodiments of the present application provide a control method, device and storage medium of a rotor dehumidifier. The method comprises obtaining a first environmental parameter for representing the dew point of mixed air, and obtaining a second environmental parameter for representing the dew point of supply air, the mixed air being air mixed after the front rotor of the rotor dehumidifier flows out and the supply air being air transported by the rotor dehumidifier to a space where the rotor dehumidifier is applied; adjusting the valve opening degree of the front regenerative heating coil of the rotor dehumidifier based on the first environmental parameter, and adjusting the valve opening degree of the rear regenerative heating coil of the rotor dehumidifier based on the second environmental parameter. The scheme of the present application realizes the synchronous adjustment of the valve opening degrees of the front regenerative coil and the rear regenerative coil, improves the precision of the coil control, realizes the stable operation of the front regenerative coil and the rear regenerative coil, reduces the fluctuation, and thus reduces the efficiency of the rotor dehumidifier. At the same time, based on the above-mentioned precise control of the valve opening degrees of the front regenerative coil and the rear regenerative coil, the setting of the temperature range of the front regenerative coil and the rear regenerative coil is cancelled, the temperature control of the front regenerative coil and the rear regenerative coil is realized in the process of valve opening degree control, the temperature of the front regenerative coil and the rear regenerative coil automatically changes with different regions, different seasons and other external factors, and finally the automatic adjustment of the coil temperature is realized.

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

[0061] As shown in Figure 1 The control method of the rotor dehumidifier can comprise the following steps:

[0062] Step 101, obtaining a first environmental parameter for representing the dew point of mixed air, and obtaining a second environmental parameter for representing the dew point of supply air, the mixed air being air mixed after the front rotor of the rotor dehumidifier flows out and the supply air being air transported by the rotor dehumidifier to a space where the rotor dehumidifier is applied;

[0063] Step 102, adjusting the valve opening degree of the front regenerative heating coil of the rotary dehumidifier based on the first environmental parameter, and adjusting the valve opening degree 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. The dew point refers to the temperature at which the gaseous water contained in the air reaches saturation and condenses 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 the same type of parameter or different types of parameters.

[0065] In practical applications, the humidity of the supply air is usually low, so in order to improve the dehumidification efficiency of the rotary dehumidifier, the supply air is delivered as return air to the mixing point between the front rotary dehumidifier and the front air supply fan, and the mixing of the air flowing out of the front rotary dehumidifier and the return air is completed at the mixing point, which helps to reduce the dehumidification amount of the rear rotary dehumidifier and quickly obtain air that meets the indoor humidity requirements. Therefore, the first environmental parameter of the mixing point can accurately reflect the dehumidification effect of the front rotary dehumidifier, and adjusting the valve opening degree of the front regenerative heating coil using the first environmental parameter helps to 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 rotary dehumidifier and the dehumidification efficiency of the rear rotary dehumidifier. The target humidity is used to indicate the desired humidity of the space. It should be understood that in the case where the humidity of the mixing point collected differs greatly from the target humidity, even if the rear rotary dehumidifier operates at the highest efficiency, the humidity of the space may still not reach the target humidity, so in this case, it is expected that the front rotary dehumidifier has a better dehumidification efficiency, and the mixed air at the mixing point has a lower dew point. On the contrary, in the case where the humidity of the mixing point collected is similar to the target humidity, further dehumidification of the rear rotary dehumidifier can make the humidity of the air delivered to the space reach the target humidity, so in this case, in order to save energy, the mixed air at the mixing point can be set to have a suitable dew point, and the supply air can also be set to have a suitable dew point.

[0067] In one example, the first environmental parameter is expressed by a first humidity, and the second environmental parameter is expressed by a second humidity. When determining the first humidity and the second humidity based on the target humidity, the dehumidification efficiency of the front rotary dehumidifier and the dehumidification efficiency of the rear rotary dehumidifier, the calculation formula of the first humidity and the second humidity is as follows:

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

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

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

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

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

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

[0074] It should be understood that in actual application, the first environment parameter and the second environment parameter can also be empirical values, i.e., 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 the environment parameters and the valve opening degree, so after obtaining the first environment parameter and the second environment parameter, the first environment parameter and the second environment parameter are used to query the mapping relationship respectively, to obtain the first valve opening degree corresponding to the first environment parameter and the second valve opening degree corresponding to the second environment parameter. In actual application, when adjusting the valve opening degree of the front regenerative heating coil or the valve opening degree of the rear regenerative heating coil, in order to improve the control precision, PID control can be used.

[0076] In the technical scheme provided in this embodiment, the first environment parameter representing the dew point of the mixed air and the second environment parameter representing the dew point of the supply air are obtained, and the first environment parameter is used to adjust the opening degree of the front regenerative heating coil, and the second environment parameter is used to adjust the opening degree of the rear regenerative heating coil. The use of the scheme of the present application realizes the synchronous adjustment of the valve opening degrees of the front regenerative coil and the rear regenerative coil, improves the precision of the coil control, realizes the stable operation of the front regenerative coil and the rear regenerative coil, reduces the fluctuation, and thus reduces the efficiency of the rotating dehumidifier. At the same time, based on the above-mentioned precise control of the valve opening degrees of the front regenerative coil and the rear regenerative coil, the temperature range of the front regenerative coil and the rear regenerative coil is cancelled, and the temperature control of the front regenerative coil and the rear regenerative coil is realized in the process of valve opening degree control, so that the temperature of the front regenerative coil and the rear regenerative coil automatically changes with different regions, different seasons and other external factors, and finally the automatic adjustment of the coil temperature is realized.

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

[0078] In one or more embodiments of the present application, the first environmental parameter used to represent the dew point of the mixed air can comprise:

[0079] Obtaining a plurality of environmental parameters used to represent the dew point of the mixed air in a preset historical time period;

[0080] Calculating a parameter mean of the plurality of environmental parameters;

[0081] Taking the parameter mean as the first environmental parameter.

[0082] In the present embodiment, the preset historical time period includes but is not limited to a historical time period covering different seasons or different weather conditions. In the application, the historical time period can be set artificially according to experience or according to the requirements of the working condition. For example, the historical time period can be set as a whole year.

[0083] In the application, a sensor can be arranged at the mixing point to collect the environmental parameter used to represent the dew point of the mixed air at different time points in the preset historical time period.

[0084] It should be understood that the front runner regenerative load comes from fresh air and return air, and the state parameters of the fresh air change over time, while the state parameters of the return air are basically unchanged, so the temperature and humidity of the front runner regenerative load will change with time and season. When the first environmental parameter is set as the parameter mean of the plurality of environmental parameters, since the parameter mean of the plurality of environmental parameters is basically a constant value, taking the parameter mean as the first environmental parameter can make the air humidity treated by the rear runner basically maintain a constant value, which helps the rear runner to run smoothly, and further helps to save the energy consumption of the runner dehumidifier.

[0085] In the scheme provided in the present embodiment, taking the parameter mean of the plurality of environmental parameters as the first environmental parameter helps the rear runner to run smoothly, and further helps to save the energy consumption of the runner dehumidifier.

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

[0087] In one or more embodiments of the present application, the second environmental parameter used to represent the dew point of the supply air can comprise:

[0088] Collecting a space environmental parameter and detecting a supply environmental parameter, the space environmental parameter being used to represent the dew point of the air in the space, and the supply environmental parameter being used to represent the dew point of the air flowing out from the rear blower of the runner dehumidifier;

[0089] The second environment parameter is determined based on the space environment parameter, the supply air environment parameter and the preset environment parameter.

[0090] It should be understood that the space to which the rotary dehumidifier is applied includes, but is not limited to, a workshop of a factory, a laboratory and the like. In the application, a temperature sensor or a humidity sensor can be arranged in the space to collect the space environment parameter. Similarly, a temperature sensor or a humidity sensor can be arranged at the air outlet of the post-supply air fan to detect the supply air environment parameter.

[0091] In this embodiment, the preset environment parameter is an environment parameter of air in the space desired by a user. The preset environment parameter can be set by the user according to actual needs. In actual application, one of the space environment parameter, the supply air environment parameter and the preset environment parameter can be randomly selected as the second environment parameter. Of course, the space environment parameter, the supply air environment parameter and the preset environment parameter can also be weighted to obtain the second environment parameter. In the process of weighting, the weights of the environment parameters in the space environment parameter, the supply air environment parameter and the preset environment parameter can be set artificially according to experience.

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

[0093] Similarly, a mapping relationship between the weighted environment parameter and the valve opening degree can also be set, so that in the case that the space environment parameter, the supply air environment parameter and the preset environment parameter are weighted to obtain the second environment parameter, the valve opening degree corresponding to the second environment parameter can be found. In order to simplify the setting of the mapping relationship, the environment parameters in the mapping relationship can also be represented in intervals in this case.

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

[0095] The above description of each embodiment tends to emphasize the differences between the embodiments, and the same or similar parts can be referred to each other. For the sake of brevity, the same or similar parts will not be described herein.

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

[0097] selecting an environment parameter with the largest parameter value from the space environment parameter, the supply air environment parameter and the preset environment parameter;

[0098] taking the environment parameter with the largest parameter value as the second environment parameter.

[0099] Taking the space environment parameter, the supply air environment parameter and the preset environment parameter as the dew point temperature for example, assuming that the preset dew point temperature is -30℃, the space dew point temperature is -29℃ and the supply air dew point temperature is -32℃, the dew point temperature with the largest value is -29℃, and thus the dew point temperature represented by the second environment parameter is -29℃.

[0100] In the technical solution provided in the present embodiment, the environment parameter with the largest parameter value is selected from the space environment parameter, the supply air environment parameter and the preset environment parameter, which is the environment parameter with the least ideal dew point, and thus it is helpful to make the three environment parameters meet the space humidity generation requirement.

[0101] The above description of each embodiment tends to emphasize the differences between each embodiment, and the same or similar parts can be referred to each other, and for the sake of brevity, the same or similar parts will not be described herein.

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

[0103] obtaining a target function relationship and a current temperature of the collection space, the target function relationship being used to reflect the change rule of the space temperature of the space changing with the operating frequency of the rear supply air fan of the rotary dehumidifier;

[0104] inputting the current temperature into the target function relationship to obtain the current operating frequency of the rear supply air fan;

[0105] controlling the rear supply air fan to operate at the current operating frequency.

[0106] In the present embodiment, the target function relationship can be a linear function relationship of the space temperature changing with the operating frequency of the rear supply air fan. In the linear function relationship, the slope of the linear function relationship can be set artificially according to the need or according to the operating condition of the rotary dehumidifier.

[0107] In the related art, the operation frequency of the rear blower of the rotary dehumidifier is adjustable, but the rear blower has no automatic frequency conversion function and cannot change the operation frequency with the change of the temperature and humidity of the workshop, so the variable air volume operation of the rear blower cannot be realized. In the technical solution provided in the embodiment, a target function relationship reflecting the change rule of the space temperature of the space with the operation frequency of the rear blower of the rotary dehumidifier is set. By using the function relationship and combining the current temperature of the space, the current operation frequency matched with the current temperature of the space can be calculated, and the rear blower is controlled to operate at the current operation frequency, so that the variable air volume operation of the rear blower is realized, which helps to save the energy consumption of the rotary dehumidifier.

[0108] The above description of each embodiment tends to emphasize the differences between each embodiment, and the same or similar parts can be referred to each other, and for the sake of brevity, the same or similar parts will not be described herein.

[0109] In one or more embodiments of the present application, the target function relationship is obtained, comprising:

[0110] The first space temperature of the space when the rear blower operates at the minimum operation frequency is collected, and the second space temperature of the space when the rear blower operates at the maximum operation frequency is collected;

[0111] The target function relationship is obtained based on the minimum operation frequency, the first space temperature, the maximum operation frequency and the second space temperature.

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

[0113] In order to improve the accuracy of the obtained first space temperature and second space temperature, the first space temperature and the second space temperature can each be the average of the space temperatures collected within a period of time. That is, the first space temperature is the average of all space temperatures collected when the rear blower operates at the minimum operation frequency for a period of time, and the second space temperature is the average of all space temperatures collected when the rear blower operates at the maximum operation frequency for a period of time.

[0114] In the embodiment, the slope can be calculated directly based on the minimum operation frequency, the first space temperature, the maximum operation frequency and the second space temperature, and the linear function relationship can be obtained based on the slope, so that the linear function relationship is taken as the target function relationship.

[0115] Wherein, the slope = (the maximum operation frequency - the minimum operation frequency) / (the second space temperature - the first space temperature)

[0116] The linear function relationship can be Y=KX, where K is a slope.

[0117] In the scheme provided by the embodiment, the target function relationship is obtained based on the first space temperature collected when the return air fan operates at the minimum operating frequency and the second space temperature collected when the return air fan operates at the maximum operating frequency. The scheme is simple and easy to implement, and the minimum operating frequency and the maximum operating frequency are the frequencies allowed for normal operation of the return air fan, so the return air fan will not be damaged.

[0118] The above description of each embodiment tends to emphasize the differences between each embodiment, and the same or similar parts can be referred to each other. For brevity, the same or similar parts will not be described again.

[0119] In one or more embodiments of the application, the target function relationship is obtained based on the minimum operating frequency, the first space temperature, the maximum operating frequency, and the second space temperature, which can include:

[0120] The target linear function relationship is calculated based on the minimum operating frequency, the first space temperature, the maximum operating frequency, and the second space temperature.

[0121] The slope of the target linear function relationship is adjusted based on the operating parameter of the rotary dehumidifier to obtain the target function relationship.

[0122] In the embodiment, the operating parameter of the rotary dehumidifier is used to reflect the energy consumption of the rotary dehumidifier. In the case where the energy consumption reflected by the operating parameter exceeds the set energy consumption interval, the slope of the target linear function relationship can be increased or decreased. In the case where the energy consumption reflected by the operating parameter does not exceed the set energy consumption interval, the slope of the target linear function relationship can not be adjusted, i.e. in this case, the target linear function relationship is the target function relationship.

[0123] It should be understood that the energy consumption exceeding the set energy consumption interval includes the energy consumption being greater than the maximum value in the energy consumption interval or being less than the minimum value in the energy consumption interval. In the case where the energy consumption is greater than the maximum value in the energy consumption interval, the slope of the target linear function relationship can be decreased. In the case where the energy consumption is less than the minimum value in the energy consumption interval, the slope of the target linear function relationship can be increased.

[0124] In the application, the operating parameter of the rotary dehumidifier can also be displayed to the user through a human-computer interaction interface supported by an electronic device. The user can adjust the slope of the target linear function relationship according to experience or actual needs and in reference to the operating parameter.

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

[0126] The above description of various embodiments tends to emphasize differences between various embodiments, and the same or similar parts can be referred to each other, which will not be described herein for the sake of brevity.

[0127] For the technical solutions given in the above embodiments, a specific embodiment is used to comprehensively describe the scheme of the present application. Taking a workshop as an example in which a rotary dehumidifier is applied, Figure 2 A specific implementation flowchart of a control method of a rotary dehumidifier according to an exemplary embodiment of the present application is shown, which includes the following steps:

[0128] Step 201, obtaining a plurality of dew point temperatures of a mixing point in a rotary dehumidifier in the last year.

[0129] Among them, the last year refers to the last year of the current year. For example, if the current year is 2023, then the last year refers to 2022.

[0130] Among them, the plurality of dew point temperatures include but are not limited to the dew point temperatures collected as collection units per day, per week, per month or per quarter, etc.

[0131] Step 202, calculating the temperature mean of the plurality of dew point temperatures.

[0132] It should be understood that if the plurality of dew point temperatures are collected as collection units per day, then the temperature mean refers to the sum of the plurality of dew point temperatures divided by the total number of collection days. If the plurality of dew point temperatures are collected as collection units per week, then the temperature mean refers to the sum of the plurality of dew point temperatures divided by the total number of weeks. In turn, the temperature mean of the dew point temperatures collected per month or per quarter can be calculated.

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

[0134] Among them, the temperature mean obtained can be used to query the pre-set mapping relationship between the mean value and the valve opening to obtain the valve opening of the front regeneration coil.

[0135] Step 204, obtaining the workshop dew point temperature, the supply air dew point temperature and the pre-set expected dew point temperature of the air in the workshop.

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

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

[0138] It should be understood that the present embodiment does not limit the execution sequence between step 201-step 203 and step 204-step 206, i.e., step 201-step 203 can be executed before step 204-step 206, or after step 204-step 206, or even synchronously.
