Description

Technical Field

[0001] This application relates to the field of environmental monitoring, and more specifically, to a dehumidifier control method and device, a dehumidifier, and a storage medium. Background Technology

[0002] Dehumidifiers in related technologies use desiccant coated on a rotating wheel to physically adsorb moisture in the air. The desiccant is then heated and vaporized by a heater as it slowly rotates, allowing it to be dehydrated, regenerated, and reused.

[0003] However, dehumidifiers in related technologies have a delay in adjusting indoor humidity, resulting in large fluctuations in indoor humidity. Summary of the Invention

[0004] The purpose of this application is to provide a dehumidifier control method, a dehumidifier, a dehumidifier control device, and a computer-readable storage medium, which can adjust humidity more promptly and reduce humidity fluctuations.

[0005] In a first aspect, this application provides a dehumidifier control method, the dehumidifier including a fresh air outlet and a heater, the dehumidifier control method including: obtaining the supply air humidity of the fresh air supplied from the fresh air outlet; determining whether the supply air humidity exceeds a preset supply air humidity range; if the supply air humidity exceeds the preset supply air humidity range, adjusting the heating power of the heater.

[0006] Compared with related technologies, the dehumidifier control method provided in this application embodiment obtains the humidity of the fresh air delivered from the fresh air outlet of the dehumidifier as the supply air humidity. When the supply air humidity exceeds the preset supply air humidity range, the heating power of the heater is adjusted. Adjusting the heating power of the heater can regulate the supply air humidity. After adjusting the supply air humidity, the humidity in the dehumidification space such as the workshop, warehouse, and greenhouse that receives the fresh air will be regulated. Compared with related technologies, which only adjust humidity when the humidity in the dehumidification space exceeds a threshold, this application embodiment adjusts the heating power of the heater in advance based on whether the supply air humidity exceeds the preset supply air humidity range, which can regulate the humidity in the dehumidification space more promptly and reduce humidity fluctuations in the dehumidification space.

[0007] In an optional implementation, the preset supply air humidity range is greater than a first preset humidity and less than a second preset humidity. Adjusting the heating power of the heater if the supply air humidity exceeds the preset supply air humidity range includes: reducing the heating power of the heater if the supply air humidity is less than or equal to the first preset humidity, and increasing the heating power of the heater if the supply air humidity is greater than or equal to the second preset humidity. Reducing the heating power of the heater when the supply air humidity is less than or equal to the first preset humidity can increase the humidity of the fresh air, thereby increasing both the supply air humidity and the ambient humidity. Increasing the heating power of the heater when the supply air humidity is greater than or equal to the second preset humidity can reduce the humidity of the fresh air, thereby reducing both the supply air humidity and the ambient humidity.

[0008] In an optional embodiment, the dehumidifier control method further includes: acquiring the ambient humidity of the dehumidification space; determining whether the ambient humidity exceeds a preset ambient humidity range; and if the ambient humidity exceeds the preset ambient humidity range, adjusting the heating power of the heater. By adjusting the heating power of the heater based on whether the ambient humidity of the dehumidification space exceeds the preset ambient humidity range, dual control of the humidity in the dehumidification space is achieved, resulting in more precise humidity control.

[0009] In an optional implementation, the preset supply air humidity range is exactly the same as the preset space humidity range. This improves the synchronization of the heating power of the supply air humidity and space humidity regulating heaters.

[0010] In an optional implementation, the preset supply air humidity range is greater than a first preset humidity and less than a second preset humidity, and the preset space humidity range is greater than a third preset humidity and less than a fourth preset humidity, wherein the first preset humidity is greater than the third preset humidity, and the second preset humidity is less than the fourth preset humidity. This ensures that the minimum supply air humidity is higher than the minimum space humidity. When the supply air humidity is lower than the first preset humidity, the heater's heating power is adjusted to increase the humidity of the fresh air, reducing the possibility that the humidity in the dehumidified space will drop below the third preset humidity. Conversely, the maximum supply air humidity is lower than the maximum space humidity. When the supply air humidity is higher than the second preset humidity, the heater's heating power is adjusted to decrease the humidity of the fresh air, reducing the possibility that the humidity in the dehumidified space will rise above the fourth preset humidity, thus reducing humidity fluctuations in the dehumidified space.

[0011] In an optional implementation, the preset supply air humidity range is greater than a first preset humidity and less than a second preset humidity, and the preset space humidity range is greater than a third preset humidity and less than a fourth preset humidity, wherein the first preset humidity is less than the third preset humidity, and the second preset humidity is greater than the fourth preset humidity. Thus, when there are large fluctuations in humidity within the dehumidification space, the supply air humidity can be lower than the third preset humidity or higher than the fourth preset humidity, allowing for faster adjustment of large humidity fluctuations within the dehumidification space.

[0012] In an optional implementation, the dehumidifier control method further includes: acquiring an input humidity range input by the user; and updating the preset supply air humidity range and / or the preset space humidity range based on the input humidity range. Updating the preset supply air humidity range and / or the preset space humidity range based on the user-input humidity range allows for adjustments based on different production and living conditions, improving the dehumidifier's applicability.

[0013] Secondly, this application provides a dehumidifier, a fresh air inlet and a fresh air outlet, a first impeller and a blower disposed between the fresh air inlet and the fresh air outlet, the first impeller containing a desiccant, the first impeller including a first drying zone and a first regeneration zone, the first drying zone being disposed between the fresh air inlet and the fresh air outlet, and the blower's air outlet direction facing the first drying zone; a first humidity sensor disposed at the fresh air outlet for measuring the supply air humidity of the fresh air delivered from the fresh air outlet; a regeneration air inlet and a regeneration air outlet, and a first heater disposed between the regeneration air inlet and the regeneration air outlet, the first regeneration zone being disposed between the first heater and the regeneration air outlet; and a control device for acquiring the supply air humidity, determining whether the supply air humidity exceeds a preset supply air humidity range, and adjusting the heating power of the first heater when the supply air humidity exceeds the preset supply air humidity range.

[0014] Compared with related technologies, in the dehumidifier provided in this application embodiment, the control device obtains the humidity of the fresh air delivered from the fresh air outlet of the dehumidifier as the supply air humidity. When the supply air humidity exceeds the preset supply air humidity range, the heating power of the first heater is adjusted. Increasing the heating power of the first heater can improve the dehydration effect of the desiccant in the first regeneration zone. The desiccant with a better dehydration effect can better absorb the moisture in the fresh air when it moves to the first drying zone, thus reducing the supply air humidity. Decreasing the heating power of the first heater can reduce the dehydration effect of the desiccant in the first regeneration zone. The desiccant with a worse dehydration effect can absorb less moisture in the fresh air when it moves to the first drying zone, thus increasing the supply air humidity. After adjusting the supply air humidity, the humidity in the dehumidification space such as the warehouse or greenhouse that receives the fresh air will be adjusted. Compared with related technologies, which adjust humidity only when the humidity in the dehumidification space exceeds a threshold, this application embodiment adjusts the heating power of the heater in advance according to whether the supply air humidity exceeds the preset supply air humidity range, which can adjust the humidity in the dehumidification space more promptly and reduce humidity fluctuations in the dehumidification space.

[0015] In an optional embodiment, the dehumidifier further includes a second humidity sensor, which is disposed within the dehumidification space and used to measure the humidity of the dehumidification space. The control device is also used to acquire the humidity of the space, determine whether the humidity exceeds a preset humidity range, and adjust the heating power of the first heater when the humidity exceeds the preset humidity range. By adjusting the heating power of the heater based on whether the humidity of the dehumidification space exceeds the preset humidity range, the control device achieves dual control of the humidity of the dehumidification space, resulting in more precise humidity control.

[0016] In an optional embodiment, the dehumidifier further includes: a second impeller, the second impeller comprising a second drying zone and a second regeneration zone, the second drying zone being disposed between the fresh air inlet and the first drying zone, and the second regeneration zone being disposed between the first regeneration zone and the regeneration air outlet; a return air inlet and a return air outlet, the return air inlet communicating with the dehumidification space, and the return air outlet being disposed between the second impeller and the first impeller; and a second heater, the second heater being disposed between the first regeneration zone and the second regeneration zone. The control device is further configured to adjust the heating power of the second heater when the supply air humidity exceeds the preset supply air humidity range or the space humidity exceeds the preset space humidity range. The return air inlet and return air outlet allow for the extraction of air from the dehumidification space, forming a circulating airflow within the dehumidification space, thus improving the humidity control efficiency within the dehumidification space. The second impeller dries the fresh air, reducing the humidity of a small amount of fresh air entering the dehumidification space through the return air outlet and return air inlet. By adjusting the heating power of the first heater and the second heater, the supply air humidity can be better regulated, thereby improving the humidity regulation effect within the dehumidification space and reducing humidity fluctuations within the dehumidification space.

[0017] Thirdly, this application provides a dehumidifier control device, the dehumidifier including a fresh air outlet and a heater, the dehumidifier control device including: a communication module, the communication module being used to acquire the supply air humidity of the fresh air supplied from the fresh air outlet; a judgment module, the judgment module being used to determine whether the supply air humidity exceeds a preset supply air humidity range; and a control module, the control module being used to adjust the heating power of the heater when the supply air humidity exceeds the preset supply air humidity range.

[0018] Compared with related technologies, in the dehumidifier control device provided in this application embodiment, after the communication module obtains the humidity of the fresh air delivered from the fresh air outlet of the dehumidifier as the supply air humidity, the judgment module determines that the supply air humidity exceeds the preset supply air humidity range, and the control module adjusts the heating power of the heater. The control module's adjustment of the heater's heating power can regulate the supply air humidity. After the supply air humidity is adjusted, the humidity in the dehumidification space such as the warehouse and greenhouse that receives the fresh air will be regulated. Compared with related technologies, which only adjust humidity when the humidity in the dehumidification space exceeds the threshold, in this application embodiment, the control module adjusts the heater's heating power in advance based on whether the supply air humidity exceeds the preset supply air humidity range, which can more timely regulate the humidity in the dehumidification space and reduce humidity fluctuations in the dehumidification space.

[0019] Fourthly, this application provides a computer-readable storage medium storing a computer program, which is executed by a processor to implement the dehumidifier control method described in any of the foregoing embodiments.

[0020] Compared with related technologies, the computer program stored in the computer-readable storage medium provided in the embodiments of this application is executed by a processor to implement the dehumidifier control method as described above, and therefore has the same technical effect as the dehumidifier control method described above.

[0032] A dehumidifier is a device used to reduce the humidity of a space. It is widely used in industries and sectors with strict humidity requirements, such as industrial and agricultural production, pharmaceuticals, electronics, and food processing. There are several different types of dehumidifiers, such as... Figure 1 The diagram shows a schematic of a rotary dehumidifier according to an embodiment of this application. It includes a fresh air inlet 10 and a fresh air outlet 20, connected by a pipe. A rotary wheel 30 and a blower 40 are disposed between the fresh air inlet 10 and the fresh air outlet 20. The fresh air inlet 10 is located outdoors, and the fresh air outlet 20 is located in a dehumidification space such as a workshop, warehouse, or greenhouse. A desiccant is placed inside the rotary wheel 30. When the blower 40 is started, it draws in air from the fresh air inlet 10 to form fresh air. The fresh air is dried by the desiccant inside the rotary wheel 30 and then enters the dehumidification space through the fresh air outlet 20. The dried fresh air, with reduced humidity, effectively reduces the ambient humidity in the dehumidification space, thereby achieving dehumidification. Furthermore, the rotary dehumidifier can also reuse the desiccant, such as… Figure 1 As shown, the rotary dehumidifier also includes a regeneration air inlet 50 and a regeneration air outlet 60. The regeneration air inlet 50 and the regeneration air outlet 60 can also be connected via ducts. In different types of rotary dehumidifiers, the regeneration air inlet 50 can be as follows: Figure 1 The connection shown is between the fresh air inlet 10 and the fresh air outlet 20. It can also be connected outdoors; the specific configuration depends on the actual usage scenario and the model of the rotary dehumidifier. Please refer to... Figure 1After the blower 40 starts, it can also form an airflow, i.e., regenerated air, in the duct between the regenerated air inlet 50 and the regenerated air outlet 60. The impeller 30 is also connected between the regenerated air inlet 50 and the regenerated air outlet 60. When the regenerated air passes through the impeller 30, it can carry away the moisture in the desiccant in the impeller 30, so that the desiccant can be reused. In order to isolate the fresh air and the regenerated air, the impeller 30 can be divided into a first drying zone 31 and a first regeneration zone 32. The first drying zone 31 is located between the fresh air inlet 10 and the fresh air outlet 20, and the first regeneration zone 32 is located between the regenerated air inlet 50 and the regenerated air outlet 60. When fresh air passes through the first drying zone 31, the desiccant in the first drying zone 31 absorbs moisture from the fresh air, causing the moisture content of the desiccant to rise. As the rotor 30 rotates, the desiccant with increased moisture content rotates to the first regeneration zone 32. Regenerated air passing through the first regeneration zone 32 carries away moisture from the desiccant, causing its moisture content to decrease. As the rotor 30 rotates, the desiccant with decreased moisture content rotates back to the first drying zone 31 to absorb moisture from the fresh air again. This cycle repeats, achieving the dehumidification effect of the space. Furthermore, as... Figure 1 As shown, a first heater 70 can also be installed between the regeneration air inlet 50 and the first regeneration zone 32. The first heater 70 can heat the regeneration air, and increasing the temperature of the regeneration air can improve the dehydration effect of the regeneration air on the desiccant in the first regeneration zone 32.

[0033] The dehumidification effect of the rotary dehumidifier can be adjusted by regulating the heating power of the first heater 70. For example, when the humidity in dehumidification spaces such as workshops, warehouses, and greenhouses is too high, the heating power of the first heater 70 can be increased to reduce the humidity in the dehumidification space. Increasing the heating power of the first heater 70 can raise the temperature of the regeneration air. With a higher regeneration air temperature, the regeneration air has a better dehydration effect on the desiccant in the first regeneration zone 32. The water content of the desiccant in the first regeneration zone 32 decreases. The desiccant with lower water content, after rotating to the first drying zone 31, has a better drying effect on the fresh air, thus reducing the humidity of the fresh air. This lower humidity in the fresh air blown into the dehumidification space reduces the overall humidity. Conversely, when the humidity in dehumidification spaces such as workshops, warehouses, and greenhouses is too low, the heating power of the first heater 70 can be decreased to increase the humidity in the dehumidification space. Reducing the heating power of the first heater 70 can lower the temperature of the regenerated air. As the temperature of the regenerated air decreases, the dehydration effect of the regenerated air on the desiccant in the first regeneration zone 32 decreases, and the water content of the desiccant in the first regeneration zone 32 increases. When the desiccant with increased water content rotates to the first drying zone 31, its drying effect on the fresh air decreases, thus increasing the humidity of the fresh air. The increased humidity of the fresh air blown into the dehumidification space can increase the humidity in the dehumidification space.

[0034] However, the process of introducing fresh air into the dehumidification space to lower / raise the humidity is continuous, which leads to humidity fluctuations within the space. Using dew point (also known as dew point temperature, which refers to the temperature at which the gaseous water in the air must condense into liquid water at a constant pressure to reach saturation) as an example, humidity needs to be maintained between 10°C and 30°C in the dehumidification space. When the dew point drops below 10°C, the heating power of the first heater 70 is gradually reduced, and the fresh air supply... As the dew point gradually increases, the dew point within the dehumidification space also gradually rises. Because the fresh air has a high dew point, it takes time for the dew point within the dehumidification space to rise. When the supply dew point of the fresh air has already reached 30°C, the dew point within the dehumidification space has not yet reached 30°C. When the dew point within the dehumidification space rises above 30°C, the supply dew point of the fresh air has already exceeded 30°C. At this point, if the heating power of the first heater 70 is increased to lower the supply dew point of the fresh air, the fresh air with a dew point higher than 30°C continues to raise the dew point within the dehumidification space during this period, causing the dew point within the dehumidification space to exceed the 30°C upper limit, resulting in significant dew point fluctuations. To solve this technical problem, Embodiment 1 of this application provides a dehumidifier control method that can adjust humidity more promptly and reduce humidity fluctuations.

[0035] The dehumidifier control method provided in this application can be applied to a variety of different scenarios. For example, in the application scenario of battery production, the dehumidifier controlled by the dehumidifier control method can be a dehumidifier in a battery production workshop or battery storage warehouse; in the application scenario of automobile production, the dehumidifier controlled by the dehumidifier control method can be a dehumidifier in an automobile production workshop or automobile storage warehouse; in the application scenario of agricultural production, the dehumidifier controlled by the dehumidifier control method can be a dehumidifier in an agricultural greenhouse or agricultural product storage warehouse.

[0036] Please refer to Figure 2 Embodiment 1 of this application provides a dehumidifier control method for controlling, such as Figure 1 The rotary dehumidifier shown is controlled by the following methods:

[0037] Step S101: Obtain the supply air humidity of the fresh air delivered from the fresh air outlet.

[0038] Step S102: Determine whether the supply air humidity exceeds the preset supply air humidity range.

[0039] Step S103: If the supply air humidity exceeds the preset supply air humidity range, adjust the heating power of the heater.

[0040] Among them, such as Figure 1 As shown, the fresh air outlet is the outlet for the fresh air supplied to the dehumidification space. The fresh air enters the dehumidification space through the fresh air outlet, thereby achieving the effect of regulating the air humidity in the dehumidification space.

[0041] To obtain the humidity of fresh air supply, one can measure the humidity at the fresh air outlet. Taking a duct outlet as an example, sensors such as dew point sensors, absolute humidity (the mass of water vapor in one cubic meter of moist air), and relative humidity (the percentage of water vapor pressure in the air to the saturated water vapor pressure at the same temperature) can be installed inside the duct near the outlet to measure the humidity of the fresh air at the outlet. Alternatively, sensors can be installed outside the duct near the outlet to measure the humidity of the fresh air at the outlet.

[0042] When the sensor is installed outside the duct, the maximum distance between the sensor and the fresh air outlet can be set according to the fresh air volume to improve the accuracy of the supply air humidity. When the fresh air volume is large, the maximum distance between the sensor and the fresh air outlet can be increased accordingly, and conversely, when the fresh air volume is small, the maximum distance between the sensor and the fresh air outlet should be decreased accordingly.

[0043] Compared with related technologies, the dehumidifier control method provided in Embodiment 1 of this application obtains the humidity of the fresh air delivered from the fresh air outlet of the dehumidifier as the supply air humidity. When the supply air humidity exceeds the preset supply air humidity range, the heating power of the heater is adjusted. Adjusting the heating power of the heater can regulate the supply air humidity. After adjusting the supply air humidity, the humidity in the dehumidification space such as the workshop, warehouse, and greenhouse that receives the fresh air will be regulated. Compared with related technologies, which only adjust humidity when the humidity in the dehumidification space exceeds a threshold, this embodiment adjusts the heating power of the heater in advance based on whether the supply air humidity exceeds the preset supply air humidity range, which can regulate the humidity in the dehumidification space more promptly and reduce humidity fluctuations in the dehumidification space.

[0044] In some embodiments of this application, the preset air supply humidity range can be greater than a first preset humidity and less than a second preset humidity; if the air supply humidity exceeds the preset air supply humidity range, the heating power of the heater is adjusted, including: if the air supply humidity is less than or equal to the first preset humidity, the heating power of the heater is reduced; if the air supply humidity is greater than or equal to the second preset humidity, the heating power of the heater is increased.

[0045] The first and second preset humidity settings can be flexibly configured according to different usage scenarios and sensor types. For example, when the sensor used to measure the supply air humidity is a dew point sensor, the first and second preset humidity settings are the preset dew point values; when the sensor used to measure the supply air humidity is an absolute humidity sensor, the first and second preset humidity settings are the preset absolute humidity values; and when the sensor used to measure the supply air humidity is a relative humidity sensor, the first and second preset humidity settings are the preset relative humidity values.

[0046] When the supply air humidity is less than or equal to the first preset humidity, reducing the heating power of the heater can increase the humidity of the fresh air, thereby increasing the supply air humidity and the ambient humidity. When the supply air humidity is greater than or equal to the second preset humidity, increasing the heating power of the heater can decrease the humidity of the fresh air, thereby decreasing the supply air humidity and the ambient humidity.

[0047] In some embodiments of this application, humidity is characterized by dew point, and the first preset humidity can be, for example, -40°C, and the second preset humidity can be, for example, -28°C, etc.

[0048] Please refer to Figure 3 In other embodiments of this application, in addition to including as Figure 2 In addition to the steps shown, the dehumidifier control method may also include:

[0049] Step S201: Obtain the humidity of the dehumidified space.

[0050] Step S202: Determine whether the ambient humidity exceeds the preset ambient humidity range.

[0051] Step S203: If the ambient humidity exceeds the preset ambient humidity range, adjust the heating power of the heater.

[0052] In the embodiments of this application, Figure 3 Steps S201 to S203 shown are Figure 2 The steps S101 to S103 shown can be executed in parallel, and there is no restriction on the order of execution.

[0053] The dehumidification space refers to the area where the dehumidifier needs to regulate the air humidity. This space can vary depending on the application. For example, in battery production, the dehumidification space could be a battery production workshop or battery storage warehouse; in automobile production, it could be an automobile production workshop or automobile storage warehouse; and in agricultural production, it could be an agricultural greenhouse or agricultural product storage warehouse.

[0054] To obtain the humidity of a dehumidified space, one can install humidity sensors, such as dew point sensors, absolute humidity sensors, or relative humidity sensors, within the dehumidified space to measure the air humidity and use the measurement results as the space humidity.

[0055] Specifically, in some embodiments of this application, sensors can be set at multiple different locations in the dehumidification space to measure multiple air humidity levels, and then the mean / median of the multiple air humidity levels can be used as the space humidity.

[0056] By adjusting the heating power of the heater based on whether the humidity of the dehumidified space exceeds the preset humidity range, dual control of the humidity in the humid space can be achieved, resulting in more precise humidity control.

[0057] In some embodiments of this application, the preset space humidity range is greater than the third preset humidity and less than the fourth preset humidity, the first preset humidity is equal to the third preset humidity, and the second preset humidity is equal to the fourth preset humidity, that is, the preset space humidity range and the preset air supply humidity range are completely consistent.

[0058] The third and fourth preset humidity settings can also be flexibly configured according to different usage scenarios and sensor types. For example, when the sensor used to measure ambient humidity is a dew point sensor, the third and fourth preset humidity settings are the preset dew point values; when the sensor used to measure ambient humidity is an absolute humidity sensor, the third and fourth preset humidity settings are the preset absolute humidity values; and when the sensor used to measure ambient humidity is a relative humidity sensor, the third and fourth preset humidity settings are the preset relative humidity values.

[0059] The first preset humidity is set to be equal to the third preset humidity, and the second preset humidity is equal to the fourth preset humidity. This means that the preset space humidity range and the preset air supply humidity range are the same. The upper and lower limits of the air supply humidity and space humidity that need to be regulated can be controlled synchronously, improving the synchronicity of adjusting the heating power of the heater when adjusting the air supply humidity and space humidity.

[0060] In some embodiments of this application, the first preset humidity is greater than the third preset humidity, and the second preset humidity is less than the fourth preset humidity.

[0061] In some embodiments of this application, humidity is characterized by dew point. The first preset humidity can be, for example, -40°C, the second preset humidity can be, for example, -28°C, the third preset humidity can be, for example, -45°C, and the fourth preset humidity can be, for example, -20°C, etc. Setting the first preset humidity to be greater than the third preset humidity and the second preset humidity to be less than the fourth preset humidity means that the preset space humidity range includes the preset supply air humidity range. This allows the minimum supply air humidity to be higher than the minimum space humidity. When the supply air humidity is lower than the first preset humidity, the heating power of the heater is adjusted to increase the humidity of the fresh air, reducing the possibility that the humidity in the dehumidified space will drop below the third preset humidity. Similarly, setting the maximum supply air humidity to be lower than the maximum space humidity means that when the supply air humidity is higher than the second preset humidity, the heating power of the heater is adjusted to decrease the humidity of the fresh air, reducing the possibility that the humidity in the dehumidified space will rise above the fourth preset humidity, thus reducing humidity fluctuations in the dehumidified space.

[0062] In some embodiments of this application, the first preset humidity is less than the third preset humidity, and the second preset humidity is greater than the fourth preset humidity. In some embodiments of this application, humidity is characterized by dew point, and the first preset humidity may be, for example, -40°C, the second preset humidity may be, for example, -28°C, the third preset humidity may be, for example, -35°C, and the fourth preset humidity may be, for example, -30°C, etc.

[0063] The first preset humidity is set to be lower than the third preset humidity, and the second preset humidity is set to be higher than the fourth preset humidity. This means that the preset humidity range of the space is within the preset supply air humidity range. When there are large fluctuations in the humidity in the dehumidification space, the supply air humidity can be set to be lower than the third preset humidity or higher than the fourth preset humidity, so as to adjust the large humidity fluctuations in the dehumidification space more quickly.

[0064] In some embodiments of this application, the dehumidifier control method may further include: obtaining an input humidity range input by a user; and updating a preset supply air humidity range and / or a preset space humidity range based on the input humidity range.

[0065] Specifically, a human-machine interface could be provided on the dehumidifier, allowing users to input a humidity range. The dehumidifier receives this input as the initial humidity range and updates the preset supply air humidity range and / or preset room humidity range accordingly. For example, users can specify on the interface whether the input humidity range corresponds to a preset supply air humidity range or a preset room humidity range. When the input humidity range corresponds to the preset supply air humidity range, it can be replaced with the input humidity range; when it corresponds to the preset room humidity range, it can be replaced with the input humidity range.

[0066] The preset air supply humidity range and / or preset space humidity range are updated based on the user's input humidity range. The preset air supply humidity range and / or preset space humidity range can be changed according to different production and living conditions to improve the applicability of the dehumidifier.

[0067] Please refer to Figure 4 Embodiment 2 of this application provides a dehumidifier for reducing the air humidity in a dehumidification space 200. The dehumidifier includes: a fresh air inlet 10 and a fresh air outlet 20, the fresh air outlet 20 being connected to the dehumidification space 200; a first impeller 30 and a blower 40 disposed between the fresh air inlet 10 and the fresh air outlet 20; a desiccant disposed in the first impeller 30; the first impeller 30 including a first drying zone 31 and a first regeneration zone 32; the first drying zone 31 being disposed between the fresh air inlet 10 and the fresh air outlet 20; and the blower 40 being connected to the first drying zone 31 and supplying air into the first drying zone 31. A first humidity sensor 80 is installed at the fresh air outlet 20 to measure the humidity of the fresh air supplied from the fresh air outlet 20; a regeneration air inlet 50 and a regeneration air outlet 60 are installed between the regeneration air inlet 50 and the regeneration air outlet 60; a first heater 70 is installed between the first heater 70 and the regeneration air outlet 60; a first regeneration zone 32 is installed between the first heater 70 and the regeneration air outlet 60; and a control device 90 is used to acquire the supply air humidity, determine whether the supply air humidity exceeds the preset supply air humidity range, and adjust the heating power of the first heater 70 when the supply air humidity exceeds the preset supply air humidity range.

[0068] The first humidity sensor 80 can be of different types. For example, in some embodiments of this application, the first humidity sensor 80 can be a dew point sensor, an absolute humidity sensor, a relative humidity sensor, etc., and can be flexibly selected. In some embodiments of this application, the first humidity sensor 80 may also include a communication component. The first humidity sensor 80 is communicatively connected to the control device 90 via the communication component. After detecting the humidity of the fresh air supply, the first humidity sensor 80 can transmit the supply air humidity to the control device 90 via the communication component.

[0069] Furthermore, in some embodiments of this application, the first heater 70 may also include a communication component, and the first heater 70 is connected to the control device 90 via the communication component. When the supply air humidity exceeds the preset supply air humidity range, the control device 90 can control and adjust the heating power of the first heater 70 through the communication component of the first heater 70.

[0070] Furthermore, in the dehumidifier provided in the embodiment, the components such as the fresh air inlet 10, fresh air outlet 20, first impeller 30, blower 40, regenerated air inlet 50, and regenerated air outlet 60 can be specifically referred to. Figure 1 The dehumidifier shown is described in detail.

[0071] Compared with related technologies, in the dehumidifier provided in Embodiment 2 of this application, the control device 90 obtains the humidity of the fresh air delivered from the fresh air outlet 20 of the dehumidifier as the supply air humidity. When the supply air humidity exceeds the preset supply air humidity range, the heating power of the first heater 70 is adjusted. Increasing the heating power of the first heater 70 can improve the dehydration effect of the desiccant in the first regeneration zone 32. The desiccant with a better dehydration effect can better absorb the moisture in the fresh air when it moves to the first drying zone 31, thereby reducing the supply air humidity. Decreasing the heating power of the first heater 70 can reduce the dehydration effect of the desiccant in the first regeneration zone 32. The desiccant with a poorer water-absorbing effect can absorb less moisture from the fresh air when it is transferred to the first drying zone 31, thereby increasing the humidity of the fresh air supply. After the humidity of the fresh air supply is adjusted, the humidity in the dehumidification space 200, such as the warehouse or greenhouse, will be regulated. Compared with related technologies, which only adjust the humidity when the humidity in the dehumidification space 200 exceeds the threshold, this embodiment adjusts the heating power of the first heater 70 in advance according to whether the humidity of the fresh air supply exceeds the preset humidity range. This allows for more timely adjustment of the humidity in the dehumidification space and reduces humidity fluctuations.

[0072] Please refer to Figure 5 In some other embodiments of this application, the dehumidifier may further include: a second humidity sensor 100, which is disposed in the dehumidification space 200 and is used to measure the humidity of the dehumidification space 200; the control device 90 is also used to acquire the humidity of the space, determine whether the humidity of the space exceeds a preset humidity range, and adjust the heating power of the first heater 70 when the humidity of the space exceeds the preset humidity range.

[0073] The first humidity sensor 80 can be of different types. For example, in some embodiments of this application, the second humidity sensor 100 can be a dew point sensor, an absolute humidity sensor, a relative humidity sensor, etc., and can be flexibly selected. In some embodiments of this application, the second humidity sensor 100 may also include a communication component. The second humidity sensor 100 is communicatively connected to the control device 90 via the communication component. After detecting the humidity of the fresh air supply, the second humidity sensor 100 can transmit the supply air humidity to the control device 90 via the communication component.

[0074] Furthermore, in some embodiments of this application, the number of second humidity sensors 100 can be multiple, and the multiple second humidity sensors 100 are respectively disposed at different positions in the dehumidification space 200. Each second humidity sensor 100 measures the humidity at different positions in the dehumidification space 200, and the control device 90 can use the mean / median / maximum / minimum value of the humidity at each different position as the space humidity of the dehumidification space 200.

[0075] The control device 90 adjusts the heating power of the first heater 70 by determining whether the humidity of the dehumidification space 200 exceeds the preset humidity range, thereby achieving dual control of the humidity of the dehumidification space and achieving a more precise humidity control effect.

[0076] Please continue to refer to Figure 5 In some other embodiments of this application, the dehumidifier may further include: a second impeller 110, which includes a second drying zone 111 and a second regeneration zone 112. The second drying zone 111 is disposed between the fresh air inlet 10 and the first drying zone 31, and the second regeneration zone 112 is disposed between the first regeneration zone 32 and the regeneration air outlet 60; a return air inlet 120 and a return air outlet 130, wherein the return air inlet 120 is disposed within the dehumidification space 200, and the return air outlet 130 is disposed between the first impeller 30 and the second impeller 110. After the blower 40 is started, it can draw air from the dehumidification space 200 to form return air. A second heater 140 is disposed between the first regeneration zone 32 and the second regeneration zone 112. The control device 90 is used to adjust the heating power of the second heater 140 when the supply air humidity exceeds a preset supply air humidity range or the space humidity exceeds a preset space humidity range.

[0077] The second rotor 110 is also equipped with a desiccant. The second drying zone 111 of the second rotor 110 is located between the fresh air inlet 10 and the first drying zone 31, which can dry the fresh air in one round. The dried fresh air is sent into the second rotor 30 for further drying, thereby improving the drying effect of the fresh air.

[0078] Furthermore, in some embodiments of this application, the second heater 140 may also include a communication component. The second heater 140 is connected to the control device 90 via the communication component. When the supply air humidity exceeds the preset supply air humidity range or the space humidity exceeds the preset space humidity range, the control device 90 can control and adjust the heating power of the first heater 70 through the communication component of the second heater 140.

[0079] By setting up a return air inlet 120 and a return air outlet 130, air can be drawn from the dehumidification space 200 to form a circulating airflow within the dehumidification space 200, thereby improving the humidity control efficiency within the dehumidification space 200. The second rotor 110 can dry the fresh air, reducing the humidity of a small amount of fresh air entering the dehumidification space through the return air outlet 130 and the return air inlet 120. By adjusting the heating power of the first heater 70 and the second heater 140, the humidity of the supplied air can be better regulated, thereby improving the humidity regulation effect within the dehumidification space and reducing humidity fluctuations within the dehumidification space.

[0080] Furthermore, in some other embodiments of this application, such as Figure 5 As shown, the dehumidifier may also include multiple surface coolers 150 disposed between the fresh air inlet 10 and the fresh air outlet 20, which can further enhance the drying effect on the fresh air. A blower 160 disposed between the first impeller 30 and the second impeller 110 can increase the wind speed of the regenerated air and improve the dehydration effect on the desiccant in the first regeneration zone 32 and the second regeneration zone 112.

[0081] Please refer to Figure 6 Embodiment 3 of this application provides a dehumidifier control device, including: a communication module 601 for acquiring the supply air humidity of the fresh air delivered from the fresh air outlet; a judgment module 602 for judging whether the supply air humidity exceeds a preset supply air humidity range; and a control module 603 for adjusting the heating power of the heater when the supply air humidity exceeds the preset supply air humidity range.

[0082] Compared with related technologies, in the dehumidifier control device provided in Embodiment 3 of this application, after the communication module 601 obtains the humidity of the fresh air delivered from the fresh air outlet of the dehumidifier as the supply air humidity, the judgment module 602 determines that the supply air humidity exceeds the preset supply air humidity range, and the control module 603 adjusts the heating power of the heater. The control module 603's adjustment of the heater's heating power can regulate the supply air humidity. After the supply air humidity is adjusted, the humidity in the dehumidification space such as the warehouse and greenhouse that receives the fresh air will be regulated. Compared with related technologies, which only adjust humidity when the humidity in the dehumidification space exceeds the threshold, in this embodiment, the control module 603 adjusts the heater's heating power in advance according to whether the supply air humidity exceeds the preset supply air humidity range, which can more timely regulate the humidity in the dehumidification space and reduce humidity fluctuations in the dehumidification space.

[0083] In some embodiments of this application, the communication module 601 may also be used to acquire the humidity of the dehumidified space; the judgment module 602 may also be used to determine whether the humidity of the space exceeds a preset humidity range; and the control module 603 may also be used to adjust the heating power of the heater when the judgment module 602 determines that the humidity of the space exceeds the preset humidity range.

[0084] In some embodiments of this application, the communication module 601 may also be used to obtain the input humidity range input by the user, and the judgment module 602 may also update the preset air supply humidity range and / or the preset space humidity range according to the input humidity range.
