Description

Technical Field

[0001] The present application relates to the field of environmental monitoring, and specifically, to a dehumidifier control method and device, a dehumidifier, and a storage medium. Background Art

[0002] The dehumidifier in the related art uses a desiccant coated on a rotating wheel to physically absorb moisture in the air, and through its own slow rotation, a heater heats and vaporizes the moisture, so that the desiccant is dehydrated, regenerated, and reused.

[0003] However, the dehumidifier in the related art has a delay when adjusting the indoor humidity, resulting in large fluctuations in the indoor humidity. Summary of the invention

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

[0005] In a first aspect, the present application provides a dehumidifier control method, wherein the dehumidifier includes a fresh air outlet and a heater, and the dehumidifier control method includes: obtaining the supply air humidity of the fresh air sent out of 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 the related art, in the dehumidifier control method provided in the embodiment of the present application, the humidity of the fresh air delivered from the fresh air outlet of the dehumidifier is obtained 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 play a role in adjusting the supply air humidity. After adjusting the supply air humidity of the fresh air, the humidity in the dehumidification space such as workshops, warehouses, and greenhouses where fresh air is delivered will be adjusted. Compared with the related art in which the humidity is adjusted only when the humidity in the dehumidification space exceeds a threshold value, in the embodiment of the present application, the heating power of the heater is adjusted in advance according to whether the supply air humidity of the fresh air exceeds the preset supply air humidity range. Therefore, the humidity in the dehumidification space can be adjusted more timely, thereby reducing the humidity fluctuation in the dehumidification space.

[0007] In an optional embodiment, the preset supply air humidity range is greater than the first preset humidity and less than the second preset humidity; if the supply air humidity exceeds the preset supply air humidity range, adjusting the heating power of the heater includes: if the supply air humidity is less than or equal to the first preset humidity, reducing the heating power of the heater; if the supply air humidity is greater than or equal to the second preset humidity, increasing the heating power of the heater. 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 space humidity; when the supply air humidity is greater than or equal to the second preset humidity, increasing the heating power of the heater can reduce the humidity of the fresh air, thereby reducing the supply air humidity and the space humidity.

[0008] In an optional embodiment, the dehumidifier control method further includes: obtaining the space humidity of the dehumidified space; determining whether the space humidity exceeds the preset space humidity range; if the space humidity exceeds the preset space humidity range, adjusting the heating power of the heater. By determining whether the space humidity of the dehumidified space exceeds the preset space humidity range and adjusting the heating power of the heater, dual control of the humidity of the dehumidified space is achieved, thereby achieving a more precise humidity control effect.

[0009] In an optional embodiment, the preset air supply humidity range is completely the same as the preset space humidity range, so that the synchronization of the air supply humidity and the heating power of the space humidity regulating heater can be improved.

[0010] In an optional embodiment, the preset supply air humidity range is greater than the first preset humidity and less than the second preset humidity, the preset space humidity range is greater than the third preset humidity and less than the fourth preset humidity, the first preset humidity is greater than the third preset humidity, and the second preset humidity is less than the fourth preset humidity. In this way, the minimum supply air humidity can 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, and reduce the possibility that the humidity in the dehumidified space drops below the third preset humidity. 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 heating power of the heater is adjusted to reduce the humidity of the fresh air, and reduce the possibility that the humidity in the dehumidified space rises above the fourth preset humidity, thereby reducing the fluctuation of the humidity in the dehumidified space.

[0011] In an optional embodiment, the preset air supply humidity range is greater than the first preset humidity and less than the second preset humidity, the preset space humidity range is greater than the third preset humidity and less than the fourth preset humidity, the first preset humidity is less than the third preset humidity, and the second preset humidity is greater than the fourth preset humidity. In this way, when the humidity in the dehumidified space fluctuates greatly, the air supply humidity can be made lower than the third preset humidity or higher than the fourth preset humidity, so that the large humidity fluctuation in the dehumidified space can be adjusted more quickly.

[0012] In an optional embodiment, the dehumidifier control method further includes: obtaining an input humidity range input by a user; and updating the preset air supply humidity range and / or the preset space humidity range according to the input humidity range. By updating the preset air supply humidity range and / or the preset space humidity range according to the input humidity range input by the user, changes can be made according to different production and living conditions to improve the applicability of the dehumidifier.

[0013] In a second aspect, the present application provides a dehumidifier, a fresh air inlet and a fresh air outlet, and a first rotor and a blower arranged between the fresh air inlet and the fresh air outlet, wherein a desiccant is arranged in the first rotor, the first rotor includes a first drying zone and a first regeneration zone, the first drying zone is arranged between the fresh air inlet and the fresh air outlet, and the air outlet direction of the blower is toward the first drying zone; a first humidity sensor, the first humidity sensor is arranged at the fresh air outlet, and is used to measure the supply air humidity of the fresh air sent out of the fresh air outlet; a regeneration air inlet and a regeneration air outlet, and a first heater arranged between the regeneration air inlet and the regeneration air outlet, the first regeneration zone is arranged between the first heater and the regeneration air outlet; a control device, the control device is used to obtain the supply air humidity, determine whether the supply air humidity exceeds a preset supply air humidity range, and adjust the heating power of the first heater when the supply air humidity exceeds the preset supply air humidity range.

[0014] Compared with the related art, in the dehumidifier provided in the embodiment of the present application, 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 better dehydration effect can better absorb the moisture in the fresh air when it is transferred to the first drying zone, thereby reducing the supply air humidity of the fresh air. Reducing the heating power of the first heater can reduce the dehydration effect of the desiccant in the first regeneration zone. The desiccant with worse dehydration effect can absorb less moisture in the fresh air when it is transferred to the first drying zone, thereby increasing the supply air humidity of the fresh air. After adjusting the supply air humidity of the fresh air, the humidity in the dehumidification space such as the warehouse and greenhouse into which the fresh air is delivered will be adjusted. Compared with the related art in which the humidity in the dehumidification space is adjusted only when the humidity exceeds the threshold value, in the embodiment of the present application, the heating power of the heater is adjusted in advance according to whether the supply air humidity of the fresh air exceeds the preset supply air humidity range, so that the humidity in the dehumidification space can be adjusted more timely, thereby reducing the humidity fluctuation in the dehumidification space.

[0015] In an optional embodiment, the dehumidifier further includes: a second humidity sensor, which is disposed in the dehumidification space and is used to measure the spatial humidity of the dehumidification space; the control device is also used to obtain the spatial humidity, determine whether the spatial humidity exceeds the preset spatial humidity range, and adjust the heating power of the first heater when the spatial humidity exceeds the preset spatial humidity range. The control device adjusts the heating power of the heater by determining whether the spatial humidity of the dehumidification space exceeds the preset spatial humidity range, thereby achieving dual control of the humidity of the dehumidification space and achieving a more accurate humidity control effect.

[0016] In an optional embodiment, the dehumidifier further includes: a second rotor, the second rotor including a second drying zone and a second regeneration zone, the second drying zone is arranged between the fresh air inlet and the first drying zone, and the second regeneration zone is arranged between the first regeneration zone and the regeneration air outlet; a return air inlet and a return air outlet, the return air inlet is connected to the dehumidified space, and the return air outlet is arranged between the second rotor and the first rotor; a second heater, the second heater is arranged between the first regeneration zone and the second regeneration zone; the control device is also used 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 the return air outlet are arranged to extract air from the dehumidified space, form a circulating airflow in the dehumidified space, and improve the control efficiency of the humidity in the dehumidified space. The second rotor can dry the fresh air and reduce the humidity of a small amount of fresh air entering the dehumidified space from the return air outlet and the return air inlet. By adjusting the heating power of the first heater and the second heater, the supply air humidity can be better adjusted, thereby improving the adjustment effect of the humidity in the dehumidified space and reducing the humidity fluctuation in the dehumidified space.

[0017] In a third aspect, the present application provides a dehumidifier control device, wherein the dehumidifier comprises a fresh air outlet and a heater, and the dehumidifier control device comprises: a communication module, wherein the communication module is used to obtain the supply air humidity of the fresh air sent out of the fresh air outlet; a judgment module, wherein the judgment module is used to judge whether the supply air humidity exceeds a preset supply air humidity range; and a control module, wherein the control module adjusts the heating power of the heater when the supply air humidity exceeds the preset supply air humidity range.

The control module adjusts the heating power of the heater to play a role in adjusting the supply air humidity. After adjusting the supply air humidity of the fresh air, the humidity in the dehumidification space such as the warehouse and greenhouse where the fresh air is delivered will be adjusted. Compared with the related art in which the humidity is adjusted only when the humidity in the dehumidification space exceeds the threshold, the control module in the embodiment of the present application adjusts the heating power of the heater in advance according to whether the supply air humidity of the fresh air exceeds the preset supply air humidity range, so that the humidity in the dehumidification space can be adjusted more timely, thereby reducing the humidity fluctuation in the dehumidification space.

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

[0031] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] A dehumidifier is a device used to reduce the humidity in a space. It is widely used in industrial and agricultural production, medicine, electronics, food industry production and other departments and industries that have strict requirements on environmental humidity. There are many different types of dehumidifiers, such as Figure 1 The figure shows a schematic diagram of the structure of a rotary dehumidifier provided by an embodiment of the present application, including: a fresh air inlet 10 and a fresh air outlet 20, the fresh air inlet 10 and the fresh air outlet 20 are connected via a pipeline, a rotor 30 and a blower 40 are arranged between the fresh air inlet 10 and the fresh air outlet 20, the fresh air inlet 10 is arranged outdoors, and the fresh air outlet 20 is arranged in a dehumidification space such as a workshop, a warehouse, and a greenhouse, and a desiccant is arranged in the rotor 30. After the blower 40 is started, it will inhale air from the fresh air inlet 10 to form fresh air, and the fresh air will be dried by the desiccant in the rotor 30 and then enter the dehumidification space through the fresh air outlet 20. The dry fresh air with reduced humidity entering the dehumidification space can effectively reduce the ambient humidity in the dehumidification space, thereby achieving a dehumidification effect. In addition, the rotary dehumidifier can also realize the reuse of desiccant, such as Figure 1 As shown, the rotary dehumidifier further includes a regeneration air inlet 50 and a regeneration air outlet 60, and the regeneration air inlet 50 and the regeneration air outlet 60 can also be connected via a pipeline. In different types of rotary dehumidifiers, the regeneration air inlet 50 can be as follows Figure 1 The connection is shown between the fresh air inlet 10 and the fresh air outlet 20, or it can be connected outdoors. The specific setting can be based on the actual usage scenario and the model of the rotary dehumidifier. Figure 1After starting, the blower 40 can also form an airflow in the pipe between the regeneration air inlet 50 and the regeneration air outlet 60, that is, the regeneration air. The rotor 30 is also connected between the regeneration air inlet 50 and the regeneration air outlet 60. When the regeneration air passes through the rotor 30, it can take away the moisture in the desiccant in the rotor 30, so that the desiccant can be reused. In order to isolate the fresh air and the regeneration air, the rotor 30 can be divided into a first drying area 31 and a first regeneration area 32. The first drying area 31 is set between the fresh air inlet 10 and the fresh air outlet 20, and the first regeneration area 32 is set between the regeneration air inlet 50 and the regeneration air outlet 60. When the fresh air passes through the first drying zone 31, the desiccant in the first drying zone 31 absorbs moisture in the fresh air, and the moisture content of the desiccant increases. As the wheel 30 rotates, the desiccant with increased moisture content rotates to the first regeneration zone 32. When the regeneration air passes through the first regeneration zone 32, it takes away the moisture in the desiccant, causing the moisture content of the desiccant to decrease. As the wheel 30 rotates, the desiccant with decreased moisture content rotates to the first drying zone 31 to absorb moisture in the fresh air again. This cycle achieves the dehumidification effect of the dehumidified space. In addition, Figure 1 As shown, a first heater 70 may be provided between the regeneration air inlet 50 and the first regeneration zone 32 . The first heater 70 may heat the regeneration air. Increasing the temperature of the regeneration air may enhance the dehydration effect of the regeneration air on the desiccant in the first regeneration zone 32 .

[0033] The heating power of the first heater 70 can be adjusted to adjust the dehumidification effect of the rotary dehumidifier. For example, when the humidity in a dehumidified space such as a workshop, a warehouse, or a greenhouse is too high, the heating power of the first heater 70 can be increased to reduce the humidity in the dehumidified space. Increasing the heating power of the first heater 70 can increase the temperature of the regeneration wind. When the temperature of the regeneration wind rises, the regeneration wind 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 is reduced. After the desiccant with reduced water content is rotated to the first drying zone 31, it has a better drying effect on the fresh air, which reduces the humidity of the fresh air. The humidity of the fresh air blown into the dehumidified space can be reduced to reduce the humidity in the dehumidified space. Conversely, when the humidity in a dehumidified space such as a workshop, a warehouse, or a greenhouse is too low, the heating power of the first heater 70 can be reduced to increase the humidity in the dehumidified space. Reducing the heating power of the first heater 70 can reduce the temperature of the regeneration air. When the temperature of the regeneration air decreases, the dehydration effect of the regeneration 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. After the desiccant with increased water content rotates to the first drying zone 31, the drying effect of the fresh air is reduced, which increases the humidity of the fresh air. The increase in the humidity of the fresh air blown into the dehumidification space can increase the humidity in the dehumidification space.

[0034] However, blowing fresh air into the dehumidified space to reduce / increase the humidity of the dehumidified space is a continuous process, and this process will cause humidity fluctuations in the dehumidified space. Taking the dew point (also known as the dew point temperature, which 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. The higher the air humidity, the higher the temperature at which the gaseous water contained in the air reaches saturation and condenses into liquid water under a fixed air pressure, and the higher the dew point temperature; the lower the air humidity, the lower the temperature at which the gaseous water contained in the air reaches saturation and condenses into liquid water under a fixed air pressure, and the lower the dew point temperature) as an example to characterize humidity, it is necessary to maintain the dew point in the dehumidified space between 10°C and 30°C. When the dew point in the dehumidified space drops below 10°C, the heating power of the first heater 70 is gradually reduced, and the fresh air supply is increased. The dew point gradually rises, and the dew point in the dehumidified space gradually rises. Due to the high dew point of the fresh air, it takes a while for the dew point in the dehumidified space to rise. When the dew point of the fresh air supply has risen to 30°C, the dew point in the dehumidified space has not yet reached 30°C. When the dew point in the dehumidified space rises to exceed 30°C, the dew point of the fresh air supply has risen to above 30°C. At this time, the heating power of the first heater 70 is increased to reduce the dew point of the fresh air supply. During the period when the dew point of the fresh air is reduced to 30°C, the fresh air with a dew point higher than 30°C continues to increase the dew point in the dehumidified space, causing the dew point in the dehumidified space to exceed the dew point upper limit of 30°C, and the dew point in the dehumidified space fluctuates greatly. In order to solve this technical problem, the first embodiment of the present application provides a dehumidifier control method, which can adjust the humidity more timely and reduce humidity fluctuations.

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

[0036] Please refer to Figure 2 , Embodiment 1 of the present application provides a dehumidifier control method for Figure 1 The rotary dehumidifier shown is controlled, and the dehumidifier control method includes:

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

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

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

[0040] Among them, Figure 1 As shown, the fresh air outlet is the outlet for the fresh air sent into the dehumidification space. The fresh air enters the dehumidification space through the fresh air outlet to achieve the effect of regulating the air humidity in the dehumidification space.

[0041] To obtain the supply air humidity of the fresh air, for example, the humidity of the fresh air can be measured at the fresh air outlet. Taking the fresh air outlet as a pipe outlet as an example, a sensor such as a dew point sensor, an absolute humidity (referring to the mass of water vapor contained in each cubic meter of wet air) sensor, a relative humidity (referring to the percentage of water vapor pressure in the air to the saturated water vapor pressure at the same temperature) sensor, etc. can be set at a position near the fresh air outlet in the pipe to measure the humidity of the fresh air at the fresh air outlet to obtain the fresh air humidity; or a sensor can be set at a position near the fresh air outlet outside the pipe to measure the humidity of the fresh air at the fresh air outlet to obtain the fresh air humidity.

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

[0043] Compared with the related art, in the dehumidifier control method provided in the first embodiment of the present application, the humidity of the fresh air delivered from the fresh air outlet of the dehumidifier is obtained 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 play a role in adjusting the supply air humidity. After adjusting the supply air humidity of the fresh air, the humidity in the dehumidification space such as workshops, warehouses, and greenhouses where fresh air is delivered will be adjusted. Compared with the related art in which the humidity is adjusted only when the humidity in the dehumidification space exceeds a threshold value, in the embodiment of the present application, the heating power of the heater is adjusted in advance according to whether the supply air humidity of the fresh air exceeds the preset supply air humidity range. Therefore, the humidity in the dehumidification space can be adjusted more timely, thereby reducing the humidity fluctuation in the dehumidification space.

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

[0045] The first preset humidity and the second preset humidity can be flexibly set according to different usage scenarios and different sensor types. For example, when the sensor for measuring the humidity of the supply air is a dew point sensor, the first preset humidity and the second preset humidity are preset dew point values, when the sensor for measuring the humidity of the supply air is an absolute humidity sensor, the first preset humidity and the second preset humidity are preset absolute humidity values, and when the sensor for measuring the humidity of the supply air is a relative humidity sensor, the first preset humidity and the second preset humidity are 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 space humidity. When the supply air humidity is greater than or equal to the second preset humidity, increasing the heating power of the heater can reduce the humidity of the fresh air, thereby reducing the supply air humidity and the space humidity.

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

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

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

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

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

[0052] In the embodiments of the present application, Figure 3 Steps S201 to S203 shown in FIG. Figure 2 Steps S101 to S103 shown can be executed in parallel without limiting the order.

[0053] The dehumidification space is the space where the dehumidifier needs to adjust the air humidity. In different application scenarios, the dehumidification space may be different. For example, in the application scenario of battery production, the dehumidification space may be a battery production workshop, a battery storage warehouse, etc.; in the application scenario of automobile production, the dehumidification space may be an automobile production workshop, an automobile storage warehouse, etc.; in the application scenario of agricultural production, the dehumidification space may be an agricultural greenhouse, an agricultural product storage warehouse, etc.

[0054] To obtain the spatial humidity of the dehumidification space, for example, a humidity sensor such as a dew point sensor, an absolute humidity sensor, a relative humidity sensor, etc. is provided in the dehumidification space to measure the air humidity in the dehumidification space, and the measurement result is used as the spatial humidity.

[0055] Specifically, in some embodiments of the present application, sensors may be respectively 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 may be used as the space humidity.

[0056] By judging whether the humidity of the dehumidified space exceeds the preset humidity range, the heating power of the heater is adjusted to realize dual control of the humidity of the humid space and achieve a more precise humidity control effect.

[0057] In some embodiments of the present 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 supply air humidity range are completely consistent.

[0058] The third preset humidity and the fourth preset humidity can also be flexibly set according to different usage scenarios and different sensor types. For example, when the sensor for measuring the humidity of the space is a dew point sensor, the third preset humidity and the fourth preset humidity are preset dew point values, when the sensor for measuring the humidity of the space is an absolute humidity sensor, the third preset humidity and the fourth preset humidity are preset absolute humidity values, and when the sensor for measuring the humidity of the space is a relative humidity sensor, the third preset humidity and the fourth preset humidity are 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, that is, the preset space humidity range and the preset supply air humidity range are the same, and the upper and lower limits of the supply air humidity and space humidity that need to be regulated can be controlled synchronously, thereby improving the synchronization of adjusting the heating power of the heater when adjusting the supply air humidity and the space humidity.

[0060] In some embodiments of the present 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 the present application, the humidity is characterized by the dew point, and 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. The first preset humidity is set to be greater than the third preset humidity, and the second preset humidity is set to be less than the fourth preset humidity, that is, the preset space humidity range includes the preset supply air humidity range, so that the minimum value of the supply air humidity can be higher than the minimum value of the 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, and reduce the possibility that the humidity in the dehumidified space drops below the third preset humidity. The maximum value of the supply air humidity is lower than the maximum value of the space humidity. When the supply air humidity is higher than the second preset humidity, the heating power of the heater is adjusted to reduce the humidity of the fresh air, and reduce the possibility that the humidity in the dehumidified space rises above the fourth preset humidity, and reduce the humidity fluctuation in the dehumidified space.

[0062] In some embodiments of the present 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 the present application, the 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.

[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, that is, the preset space humidity range is within the preset supply air humidity range. When the humidity in the dehumidification space fluctuates greatly, the supply air humidity can be made 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 the present application, the dehumidifier control method may further include: obtaining an input humidity range input by a user; and updating a preset air supply humidity range and / or a preset space humidity range according to the input humidity range.

[0065] Specifically, a human-computer interaction interface may be provided on the dehumidifier, and the user may input a humidity range on the human-computer interaction interface. The dehumidifier receives the humidity range input by the user as the input humidity range, and updates the preset air supply humidity range and / or the preset space humidity range according to the input humidity range. For example, the user may determine on the human-computer interaction interface that the input humidity range corresponds to the preset air supply humidity range or the preset space humidity range. When the input humidity range corresponds to the preset air supply humidity range, the preset air supply humidity range may be replaced with the input humidity range. When the input humidity range corresponds to the preset space humidity range, the preset space humidity range may be replaced with the input humidity range.

[0066] The preset air supply humidity range and / or the preset space humidity range is updated according to the input humidity range input by the user. The preset air supply humidity range and / or the 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 the present application provides a dehumidifier for reducing the air humidity in a dehumidified space 200, the dehumidifier comprising: a fresh air inlet 10 and a fresh air outlet 20, the fresh air outlet 20 being connected to the dehumidified space 200, a first rotor 30 and a blower 40 arranged between the fresh air inlet 10 and the fresh air outlet 20, a desiccant being arranged in the first rotor 30, the first rotor 30 comprising a first drying zone 31 and a first regeneration zone 32, the first drying zone 31 being arranged between the fresh air inlet 10 and the fresh air outlet 20, 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, which is arranged at the fresh air outlet 20, and is used to measure the supply air humidity of the fresh air sent out by the fresh air outlet 20; a regeneration air inlet 50 and a regeneration air outlet 60, a first heater 70 arranged between the regeneration air inlet 50 and the regeneration air outlet 60, and a first regeneration zone 32 is arranged between the first heater 70 and the regeneration air outlet 60; a control device 90, which is used to obtain the supply air humidity, determine whether the supply air humidity exceeds the preset supply air humidity range, and when the supply air humidity exceeds the preset supply air humidity range, adjust the heating power of the first heater 70.

[0068] Among them, the first humidity sensor 80 can be different types of humidity sensors. For example, in some embodiments of the present 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 the present application, the first humidity sensor 80 can also include a communication component, and the first humidity sensor 80 is connected to the control device 90 via the communication component. After detecting the supply air humidity of the fresh air, the first humidity sensor 80 can transmit the supply air humidity to the control device 90 via the communication component.

[0069] In addition, in some embodiments of the present application, the first heater 70 may also include a communication component, and the first heater 70 is communicated with the control device 90 via the communication component. When the supply air humidity exceeds a preset supply air humidity range, the control device 90 may control and adjust the heating power of the first heater 70 through the communication component of the first heater 70.

[0070] In addition, in the dehumidifier provided in the embodiment, the fresh air inlet 10, the fresh air outlet 20, the first rotor 30, the blower 40, the regeneration air inlet 50, the regeneration air outlet 60 and other components can be specifically referred to Figure 1 Dehumidifiers shown in the specific instructions.

[0071] Compared with the related art, in the dehumidifier provided in the second embodiment of the present 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, and when the supply air humidity exceeds the preset supply air humidity range, adjusts the heating power of the first heater 70. 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 better dehydration effect can better absorb the moisture in the fresh air when it is transferred to the first drying zone 31, thereby reducing the supply air humidity of the fresh air. Reducing 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 worse dehydration effect can absorb less moisture in the fresh air when it is transferred to the first drying zone 31, thereby increasing the supply air humidity of the fresh air. After adjusting the supply air humidity of the fresh air, the humidity in the dehumidification space 200 such as the warehouse and greenhouse into which the fresh air is sent will be adjusted. Compared with the related art in which the humidity in the dehumidification space 200 is adjusted only when the humidity exceeds the threshold, the heating power of the first heater 70 is adjusted in advance according to whether the supply air humidity of the fresh air exceeds the preset supply air humidity range in the embodiment of the present application, so that the humidity in the dehumidification space can be adjusted more timely, thereby reducing the humidity fluctuation in the dehumidification space.

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

[0073] Among them, the first humidity sensor 80 can be different types of humidity sensors. For example, in some embodiments of the present 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 the present application, the second humidity sensor 100 can also include a communication component, and the second humidity sensor 100 is connected to the control device 90 via the communication component. After detecting the supply air humidity of the fresh air, 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 the present application, the number of the second humidity sensors 100 can be multiple, and the multiple second humidity sensors 100 are respectively arranged at different positions of the dehumidification space 200. Each second humidity sensor 100 respectively measures the humidity at different positions of the dehumidification space 200. The control device 90 can use the mean / median / maximum / minimum value of the humidity at each different position as the spatial humidity of the dehumidification space 200.

[0075] The control device 90 adjusts the heating power of the first heater 70 by determining whether the space humidity of the dehumidification space 200 exceeds a preset space humidity range, thereby realizing 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 the present application, the dehumidifier may further include: a second rotor 110, the second rotor 110 includes a second drying zone 111 and a second regeneration zone 112, the second drying zone 111 is arranged between the fresh air inlet 10 and the first drying zone 31, and the second regeneration zone 112 is arranged between the first regeneration zone 32 and the regeneration air outlet 60; a return air inlet 120 and a return air outlet 130, the return air inlet 120 is arranged in the dehumidification space 200, and the return air outlet 130 is arranged between the first rotor 30 and the second rotor 110, after the blower 40 is started, air can be extracted from the dehumidification space 200 to form return air. A second heater 140, the second heater 140 is arranged 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 the preset supply air humidity range, or the space humidity exceeds the preset space humidity range.

[0077] Among them, a desiccant is also arranged in the second rotor 110. The second drying zone 111 of the second rotor 110 is arranged between the fresh air inlet 10 and the first drying zone 31, which can perform a round of drying on the fresh air. The dried fresh air is sent into the second rotor 30 for further drying, thereby improving the drying effect of the fresh air.

[0078] In addition, in some embodiments of the present application, the second heater 140 may also include a communication component, and the second heater 140 is communicated with 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] The return air inlet 120 and the return air outlet 130 are provided to extract air from the dehumidification space 200, form a circulating airflow in the dehumidification space 200, and improve the control efficiency of the humidity in the dehumidification space 200. The second rotor 110 is provided to dry the fresh air, thereby 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 supply air humidity can be better adjusted, thereby improving the adjustment effect of the humidity in the dehumidification space and reducing the humidity fluctuation in the dehumidification space.

[0080] In addition, in some other embodiments of the present application, Figure 5 As shown, the dehumidifier may further include a plurality of surface coolers 150 disposed between the fresh air inlet 10 and the fresh air outlet 20. The surface coolers 150 may further improve the drying effect of the fresh air. A blower 160 disposed between the first rotor 30 and the second rotor 110 may increase the wind speed of the regeneration wind and improve the dehydration effect of the desiccant in the first regeneration zone 32 and the second regeneration zone 112.

[0082] Compared with the related art, in the dehumidifier control device provided in the third embodiment of the present 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, when the judgment module 602 determines that the supply air humidity exceeds the preset supply air humidity range, the control module 603 adjusts the heating power of the heater. The control module 603 adjusts the heating power of the heater to play a role in adjusting the supply air humidity. After adjusting the supply air humidity of the fresh air, the humidity in the dehumidification space such as the warehouse and greenhouse where the fresh air is delivered will be adjusted. Compared with the related art in which the humidity is adjusted only when the humidity in the dehumidification space exceeds the threshold, the control module 603 in the embodiment of the present application adjusts the heating power of the heater in advance according to whether the supply air humidity of the fresh air exceeds the preset supply air humidity range, so that the humidity in the dehumidification space can be adjusted more timely, thereby reducing the humidity fluctuation in the dehumidification space.
