Description

TECHNICAL FIELD

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

[0002] The dehumidifier in the related art is to use the hygroscopic agent coated on the rotating wheel to physically adsorb the moisture in the air, and through the slow rotation of the rotating wheel, the moisture is heated and vaporized by the heater to make the hygroscopic agent dehydrate and regenerate, and then the hygroscopic agent is reused.

[0003] Some dehumidifiers can not only dehumidify but also adjust the indoor temperature, and the dehumidifier in the related art has a large power consumption when adjusting the indoor temperature. SUMMARY

[0004] The purpose of the present application is to provide a dehumidifier control method and device, a dehumidifier and a computer readable storage medium, which can reduce the power consumption of the dehumidifier when adjusting the indoor temperature.

[0005] In a first aspect, the embodiments of the present application provide a dehumidifier control method, the dehumidifier comprising a processing fan, the dehumidifier control method comprising: obtaining a space temperature of a target space; determining whether the space temperature exceeds a first set temperature range for a set time length; and adjusting a fan frequency of the processing fan if the space temperature exceeds the first set temperature range for the set time length.

[0006] Compared with the related art, in the dehumidifier control method provided by the embodiments of the present application, the fan frequency of the processing fan is adjusted when the space temperature exceeds the first set temperature range for the set time length, and the change of the fan frequency can change the wind speed of the dehumidifier sending fresh air into the target space, which has an adjusting effect on the temperature in the target space. By setting the set time length, the fan frequency of the processing fan can be reduced from being changed frequently due to temperature fluctuations. Since the sudden change of the fan frequency can generate a large induced current, which can cause the energy consumption to increase, reducing the fan frequency of the processing fan from being changed frequently due to temperature fluctuations can effectively reduce the energy consumption in the temperature adjusting process.

[0007] In an optional embodiment, the first set temperature range is greater than the first set temperature; and the adjusting the fan frequency of the treatment fan, if the space temperature is out of the first set temperature range for the set time length, comprises: reducing the fan frequency of the treatment fan, if the space temperature is less than or equal to the first set temperature for the set time length. If the space temperature is less than or equal to the first set temperature for the set time length, it indicates that the space temperature in the target space is maintained at a lower state for a long time, and at this time, reducing the fan frequency of the treatment fan can reduce the air speed of the dehumidifier sending new air into the target space, reducing the possibility of further reducing the space temperature in the target space; in addition, reducing the fan frequency of the treatment fan can also effectively reduce the power of the dehumidifier and reduce the energy consumption of the dehumidifier.

[0008] In an optional embodiment, the first set temperature range is less than the second set temperature; and the adjusting the fan frequency of the treatment fan, if the space temperature is out of the first set temperature range for the set time length, comprises: increasing the fan frequency of the treatment fan, if the space temperature is greater than or equal to the second set temperature for the set time length. If the space temperature is greater than or equal to the second set temperature for the set time length, it indicates that the space temperature in the target space is maintained at a higher state for a long time, and at this time, increasing the fan frequency of the treatment fan can increase the air speed of the dehumidifier sending new air into the target space, and the space temperature in the target space can be cooled faster.

[0009] In an optional embodiment, the dehumidifier comprises a surface cooler, and the dehumidifier control method further comprises: determining whether the space temperature is out of a second set temperature range, the second set temperature range being different from the first set temperature range; and adjusting the electric proportional valve opening degree of the surface cooler, if the space temperature is out of the second set temperature range. Adjusting the electric proportional valve opening degree of the surface cooler when the space temperature is out of the second set temperature range can also play a role in adjusting the space temperature, and in combination with the adjustment of the fan frequency according to the first set temperature range, the space temperature in the target space can be better adjusted.

[0010] In an optional embodiment, the second set temperature range is greater than a third set temperature, and the first set temperature range is greater than a first set temperature; the third set temperature is less than the first set temperature, and a difference between the third set temperature and the first set temperature is greater than or equal to 0.3℃ and less than or equal to 0.7℃. Setting the third set temperature to be less than the first set temperature can reduce the possibility of the space temperature falling below the third set temperature and reduce the energy consumption of the dehumidifier when the space temperature is maintained around the third set temperature for a long time by adjusting the frequency of the fan. Setting the difference between the third set temperature and the first set temperature to be greater than or equal to 0.3℃ can reduce the problem that the adjustment of the frequency of the fan is difficult to trigger due to the too small difference, and setting the difference between the third set temperature and the first set temperature to be less than or equal to 0.7℃ can reduce the problem that the adjustment of the frequency of the fan is frequently triggered due to the too large difference.

[0011] In an optional embodiment, the second set temperature range is less than a fourth set temperature, and the first set temperature range is less than a second set temperature; the fourth set temperature is greater than the second set temperature, and a difference between the fourth set temperature and the second set temperature is greater than or equal to 0.3℃ and less than or equal to 0.7℃. Setting the fourth set temperature to be greater than the second set temperature can reduce the possibility of the space temperature rising above the fourth set temperature and reduce the energy consumption of the dehumidifier when the space temperature is maintained around the fourth set temperature for a long time by adjusting the frequency of the fan. Setting the difference between the fourth set temperature and the second set temperature to be greater than or equal to 0.3℃ can reduce the problem that the adjustment of the frequency of the fan is difficult to trigger due to the too small difference, and setting the difference between the fourth set temperature and the second set temperature to be less than or equal to 0.7℃ can reduce the problem that the adjustment of the frequency of the fan is frequently triggered due to the too large difference.

[0012] In an optional embodiment, the dehumidifier control method further comprises: displaying the frequency of the processing fan in real time. Displaying the frequency of the processing fan in real time can facilitate the staff to determine whether the processing fan fails when the indoor temperature is abnormal.

[0013] In a second aspect, the embodiments of the present application provide a dehumidifier, comprising: a fresh air inlet and a fresh air outlet, and a rotary wheel and a treatment fan arranged between the fresh air inlet and the fresh air outlet, the rotary wheel being provided with a desiccant, the rotary wheel comprising a drying zone and a regeneration zone, the drying zone being arranged between the fresh air inlet and the fresh air outlet, and the treatment fan being arranged to direct air to the drying zone; a temperature sensor arranged in a target space to measure a space temperature of the target space; and a control device configured to acquire the space temperature, determine whether the space temperature is out of a first set temperature range for a set time length, and adjust a fan frequency of the treatment fan when the space temperature is out of the first set temperature range for the set time length.

[0014] Compared with the related art, in the dehumidifier provided by the embodiments of the present application, the control device controls and adjusts the fan frequency of the treatment fan when determining that the space temperature is out of the first set temperature range for the set time length, the change of the fan frequency can change the air speed of the dehumidifier to send fresh air into the target space, and thus adjust the temperature in the target space, and the set time length can reduce the frequent change of the fan frequency of the treatment fan due to temperature fluctuation, and the sudden change of the fan frequency can generate a large induced current and cause high energy consumption, and reducing the frequent change of the fan frequency of the treatment fan due to temperature fluctuation can effectively reduce the energy consumption in the temperature adjustment process.

[0015] In an optional embodiment, the dehumidifier further comprises: a surface cooler arranged between the fresh air inlet and the fresh air outlet; and the control device is further configured to determine whether the space temperature is out of a second set temperature range, the second set temperature range being different from the first set temperature range, and adjust an electric proportional valve opening degree of the surface cooler when the space temperature is out of the second set temperature range. The control device controls and adjusts the electric proportional valve opening degree of the surface cooler when determining that the space temperature is out of the second set temperature range, which can also adjust the space temperature, and in combination with the adjustment of the fan frequency according to the first set temperature range, the space temperature of the target space can be better adjusted.

[0016] In an optional embodiment, the dehumidifier further comprises: a return air inlet and a return air outlet, the return air inlet being communicated with the target space, and the return air outlet being arranged between the treatment fan and the fresh air inlet. The return air inlet is communicated with the target space, and the return air outlet is arranged between the treatment fan and the fresh air inlet, and adjusting the fan frequency of the treatment fan can adjust the air volume of the treatment fan drawn from the target space, so as to better adjust the space temperature of the target space.

[0017] In a third aspect, an embodiment of the present application provides a dehumidifier control device, the dehumidifier comprising a processing fan, the dehumidifier control device comprising: a communication module configured to obtain a space temperature of a target space; a judgment module configured to determine whether the space temperature is maintained within a first set temperature range for a set time length; and a control module configured to adjust a fan frequency of the processing fan when the space temperature is maintained within the first set temperature range for the set time length.

[0018] Compared with the related art, in the dehumidifier control device provided by the embodiment of the present application, when the judgment module determines that the space temperature exceeds the first set temperature range for the set time length, the control module controls and adjusts the fan frequency of the processing fan. The change of the fan frequency can change the air speed of the new air sent into the target space by the dehumidifier, so as to adjust the temperature in the target space. By setting the set time length, the fan frequency of the processing fan can be reduced from being frequently changed due to the temperature fluctuation. Since the sudden change of the fan frequency can generate a large induced current, the energy consumption is increased. Reducing the fan frequency of the processing fan from being frequently changed due to the temperature fluctuation can effectively reduce the energy consumption in the temperature adjustment process.

[0035] The dehumidifier is a device for reducing the humidity of a space, which is widely used in industrial and agricultural production, medicine, electronics, food industry production and other departments and industries with strict requirements on environmental humidity. There are many different types of dehumidifiers, such as Figure 1 As shown in the structure schematic diagram of a rotary dehumidifier provided by the embodiment of the present application, it comprises 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 rotary wheel 30 and a treatment fan 40 are arranged between the fresh air inlet 10 and the fresh air outlet 20, the fresh air inlet 10 is arranged outdoors, the fresh air outlet 20 is arranged in a target space such as a workshop, a warehouse or a greenhouse, the rotary wheel 30 is provided with a desiccant, and the treatment fan 40 forms fresh air by sucking air from the fresh air inlet 10 after being started, the fresh air is dried by the desiccant in the rotary wheel 30 and then enters the target space through the fresh air outlet 20, the dry fresh air after humidity reduction can effectively reduce the environmental humidity in the target space, thereby achieving the effect of dehumidification. In addition, the dehumidifier can also realize the reuse of the desiccant, as shown in Figure 1 The dehumidifier further comprises 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 a pipeline, in different types of dehumidifiers, the regeneration air inlet 50 can be connected between the fresh air inlet 10 and the fresh air outlet 20 as shown in Figure 1 It can also be connected outdoors, and the specific connection can be set according to the actual use scene and the type of the dehumidifier. Please refer to Figure 1 The treatment fan 40 can also form an air flow, i.e. regeneration air, in the pipeline between the regeneration air inlet 50 and the regeneration air outlet 60 after being started, and the rotary wheel 30 is also connected between the regeneration air inlet 50 and the regeneration air outlet 60, the regeneration air can take away the water in the desiccant in the rotary wheel 30 when passing through the rotary wheel 30, so that the desiccant can be reused. In order to isolate the fresh air and the regeneration air, the rotary wheel 30 can be divided into a drying area 31 and a regeneration area 32, the drying area 31 is arranged between the fresh air inlet 10 and the fresh air outlet 20, and the regeneration area 32 is arranged between the regeneration air inlet 50 and the regeneration air outlet 60. When the fresh air passes through the drying area 31, the desiccant in the drying area 31 absorbs the water in the fresh air, the water content of the desiccant increases, and with the rotation of the rotary wheel 30, the desiccant with increased water content rotates to the regeneration area 32, the regeneration air takes away the water in the desiccant when passing through the regeneration area 32, so that the water content of the desiccant decreases, and with the rotation of the rotary wheel 30, the desiccant with decreased water content rotates to the drying area 31 to absorb the water in the fresh air again, thereby realizing the dehumidification effect of the target space. In addition, as shown in Figure 1As shown, a heater 70 can also be arranged between the regenerative air inlet 50 and the regeneration zone 32, and the heater 70 can heat the regenerative air, so that the temperature of the regenerative air is increased, and the dehydrating effect of the regenerative air on the desiccant in the regeneration zone 32 is improved.

[0036] Since the dehumidifier needs to blow fresh air into the target space during the dehumidification process, by controlling the variables such as the air speed and temperature of the fresh air, the dehumidifier can not only adjust the humidity of the target space, but also adjust the temperature of the target space during the operation. The embodiments of the present application provide a dehumidifier control method, device, and computer readable storage medium, which can better adjust the temperature of the target space.

[0037] The dehumidifier control method provided by the embodiments of the present application can be applied in various different scenarios, for example, in the application scenario of battery production, the dehumidifier controlled by the dehumidifier control method can be the dehumidifier of a battery production workshop or a battery storage warehouse; in the application scenario of automobile production, the dehumidifier controlled by the dehumidifier control method can be the dehumidifier of an automobile production workshop or an automobile storage warehouse; in the application scenario of agricultural production, the dehumidifier controlled by the dehumidifier control method can be the dehumidifier of an agricultural greenhouse or a farm product storage warehouse.

[0038] Please refer to Figure 2 The embodiments of the present application provide a dehumidifier control method, as shown in Figure 2 The dehumidifier control method comprises:

[0039] Step S101: Obtain the space temperature of the target space.

[0040] Step S102: Determine whether the space temperature exceeds the first set temperature range for a set time length.

[0041] Step S103: Adjust the frequency of the fan of the processing fan when the space temperature exceeds the first set temperature range for a set time length.

[0042] The target space is the space in which the dehumidifier needs to adjust the air humidity and temperature, and the target space can also be different in different application scenarios. For example, in the application scenario of battery production, the target space can be a battery production workshop, a battery storage warehouse, etc.; in the application scenario of automobile production, the target space can be an automobile production workshop, an automobile storage warehouse, etc.; in the application scenario of agricultural production, the target space can be an agricultural greenhouse, a farm product storage warehouse, etc.

[0043] The space temperature of the target space can be obtained by, for example, arranging a temperature sensor in the target space to measure the air temperature in the target space, and taking the measurement result of the temperature sensor as the space temperature.

[0044] Specifically, in different embodiments of the present application, for example, a single temperature sensor can be arranged at a set position of the target space, and the measurement result of the temperature sensor is directly taken as the space temperature. Alternatively, multiple temperature sensors can be arranged at multiple different positions of the target space to measure multiple air temperatures, and then the mean / median value of the multiple air temperatures is taken as the space temperature.

[0045] The first set temperature range can be a temperature range set in advance before the dehumidifier starts running, or a temperature range set during the running of the dehumidifier. For example, a man-machine interaction system can be arranged in the dehumidifier, and the user can set or modify the first set temperature range during the running of the dehumidifier through the man-machine interaction system.

[0046] The set time length can also be a time length set in advance before the dehumidifier starts running, or a time length set during the running of the dehumidifier. For example, the user can also set or modify the set time length during the running of the dehumidifier through the man-machine interaction system.

[0047] In some embodiments of the present application, the fan frequency refers to the rate of rotation of the fan, which is usually expressed in revolutions per minute (RPM). In industrial applications, the frequency of the fan is usually controlled by the rotation rate of the motor. Therefore, the fan frequency can also be expressed as the frequency of the motor.

[0048] Further, determining whether the space temperature exceeds the first set temperature range for the set time length can specifically be, for example, starting timing when the space temperature exceeds the first set temperature range, and determining that the space temperature exceeds the first set temperature range for the set time length when the timing time length reaches the set time length, and determining that the space temperature exceeds the first set temperature range for less than the set time length when the timing time length does not reach the set time length and the space temperature changes to not exceed the first set temperature range, and resetting the timing time length, and starting timing again when the space temperature exceeds the first set temperature range next time.

[0049] Compared with the related art, in the dehumidifier control method provided in the embodiments of the present application, the fan frequency of the processing fan is adjusted when the space temperature exceeds the first set temperature range for the set time length. The change of the fan frequency can change the air speed of the new air sent into the target space by the dehumidifier, and has a regulating effect on the temperature in the target space. By setting the set time length, the fan frequency of the processing fan can be reduced from being frequently changed due to temperature fluctuations. Since the sudden change of the fan frequency can generate a large induced current, causing the energy consumption to increase, reducing the fan frequency of the processing fan from being frequently changed due to temperature fluctuations can effectively reduce the energy consumption in the temperature regulating process.

[0050] In some embodiments of the present application, the first set temperature range can be greater than the first set temperature; if the space temperature exceeds the first set temperature range for a set time, the fan frequency of the treatment fan is adjusted, including: if the space temperature is less than or equal to the first set temperature for a set time, the fan frequency of the treatment fan is reduced.

[0051] The first set temperature can be flexibly set according to the actual application scenario. The first set temperature can also be a temperature set in advance before the dehumidifier starts running, or a temperature set or modified by the user during the running of the dehumidifier through the man-machine interaction system.

[0052] If the space temperature is less than or equal to the first set temperature for a set time, it means that the space temperature in the target space has been maintained at a low state for a long time. Corresponding to the actual application scenario, it can be that the heat dissipation of the heat source equipment in the target space is reduced, for example, when the target space is a battery production workshop, the battery production equipment in the workshop can be suspended, and the heat dissipation is reduced. At this time, reducing the fan frequency of the treatment fan can reduce the wind speed of the dehumidifier into the target space, reducing the possibility of further reducing the space temperature in the target space. In addition, reducing the fan frequency of the treatment fan can also effectively reduce the power of the dehumidifier and reduce the energy consumption of the dehumidifier.

[0053] In some embodiments of the present application, the first set temperature range is less than the second set temperature; if the space temperature exceeds the first set temperature range for a set time, the fan frequency of the treatment fan is adjusted, including: if the space temperature is greater than or equal to the second set temperature for a set time, the fan frequency of the treatment fan is increased.

[0054] The second set temperature can be flexibly set according to the actual application scenario. The second set temperature can also be a temperature set in advance before the dehumidifier starts running, or a temperature set or modified by the user during the running of the dehumidifier through the man-machine interaction system.

[0055] If the space temperature is greater than or equal to the second set temperature for a set time, it means that the space temperature in the target space has been maintained at a high state for a long time. Corresponding to the actual application scenario, it can be that the heat dissipation of the heat source equipment in the target space is increased, for example, when the target space is a battery production workshop, the power of the battery production equipment in the workshop can be increased, and the heat dissipation is increased. At this time, increasing the fan frequency of the treatment fan can increase the wind speed of the dehumidifier into the target space, and cool the space temperature in the target space faster.

[0056] In some other embodiments of the present application, please refer to Figure 3 , Figure 4 , Figure 3 The structure diagram of the dehumidifier provided by some other embodiments of the present application is shown.Figure 4 Fig. 1 shows a flowchart of a dehumidifier control method provided by some other embodiments of the present application, as shown in Figure 3 As shown, the dehumidifier can also include a surface cooler 70, which is arranged between the fresh air inlet 10 and the fresh air outlet 20. For example, as shown in Figure 3 As shown in Fig. 1, the dehumidifier can further include a surface cooler 70, which is arranged between the fresh air inlet 10 and the fresh air outlet 20. For example, as shown in Figure 4 As shown, the dehumidifier control method can further include:

[0057] Step S104: determining whether the space temperature is out of a second set temperature range, the second set temperature range being different from the first set temperature range.

[0058] Step S105: adjusting the electric proportional valve opening degree of the surface cooler when the space temperature is out of the second set temperature range.

[0059] The surface cooler 70 is a device for cooling air, and when applied to the dehumidifier, the surface cooler 70 can cool the fresh air when the fresh air passes through, so that the water vapor in the fresh air condenses in the surface cooler 70, thereby reducing the humidity of the fresh air. In some embodiments of the present application, by adjusting the electric proportional valve opening degree of the surface cooler 70, not only the humidity of the fresh air can be adjusted, but also the temperature of the fresh air can be adjusted, thereby achieving the effect of adjusting the temperature of the target space.

[0060] The second set temperature range can also be a temperature range set in advance before the dehumidifier starts running, or a temperature range set during the operation of the dehumidifier. For example, a human-computer interaction system can be arranged in the dehumidifier, and the user can set or modify the second set temperature range during the operation of the dehumidifier through the human-computer interaction system.

[0061] Adjusting the electric proportional valve opening degree of the surface cooler when the space temperature is out of the second set temperature range can also play a role in adjusting the space temperature of the target space, and in combination with the adjustment of the fan frequency according to the first set temperature range, a better adjustment effect on the space temperature of the target space can be achieved.

[0062] In some embodiments of the present application, the second set temperature range is greater than a third set temperature, and the third set temperature is less than the first set temperature, and the difference between the third set temperature and the first set temperature is greater than or equal to 0.3℃ and less than or equal to 0.7℃.

[0063] Specifically, the difference between the third set temperature and the first set temperature can be 0.4℃, 0.5℃, etc., and can be flexibly set according to actual needs.

[0064] When the space temperature is between the first set temperature and the third set temperature, the space temperature is more likely to drop below the third set temperature with fluctuations in the space temperature, resulting in frequent adjustment of the electric proportional valve opening of the surface cooler and greater energy consumption. Setting the third set temperature to be less than the first set temperature can reduce the likelihood of the space temperature dropping below the third set temperature when the space temperature is maintained near the third set temperature for a long time, and reduce the energy consumption of the dehumidifier by adjusting the fan frequency. Setting the difference between the third set temperature and the first set temperature to be greater than or equal to 0.3°C can reduce the problem that the space temperature frequently changes above and below the first set temperature due to too small a difference, and the adjustment of the fan frequency is difficult to trigger, and setting the difference between the third set temperature and the first set temperature to be less than or equal to 0.7°C can reduce the problem that the space temperature is below the first set temperature for a long time due to too large a difference, and the adjustment of the fan frequency is frequently triggered.

[0065] In some embodiments of the present application, the second set temperature range is less than the fourth set temperature; the fourth set temperature is greater than the second set temperature, and the difference between the fourth set temperature and the second set temperature is greater than or equal to 0.3°C and less than or equal to 0.7°C.

[0066] Specifically, the difference between the fourth set temperature and the second set temperature may, for example, be 0.4°C, 0.5°C, etc., and can be flexibly set according to actual needs.

[0067] When the space temperature is near the fourth set temperature, the space temperature is more likely to rise above the fourth set temperature with fluctuations in the space temperature, resulting in frequent adjustment of the electric proportional valve opening of the surface cooler and greater energy consumption. Setting the fourth set temperature to be greater than the second set temperature can reduce the likelihood of the space temperature rising above the fourth set temperature when the space temperature is maintained near the fourth set temperature for a long time, and reduce the energy consumption of the dehumidifier by adjusting the fan frequency. Setting the difference between the fourth set temperature and the second set temperature to be greater than or equal to 0.3°C can reduce the problem that the space temperature frequently changes above and below the second set temperature due to too small a difference, and the adjustment of the fan frequency is difficult to trigger, and setting the difference between the fourth set temperature and the second set temperature to be less than or equal to 0.7°C can reduce the problem that the space temperature is above the second set temperature for a long time due to too large a difference, and the adjustment of the fan frequency is frequently triggered.

[0068] In addition, in some embodiments of the present application, the dehumidifier control method can further include: displaying the fan frequency of the fan in real time.

[0069] Specifically, for example, a display can be provided in the dehumidifier, and the fan frequency of the treatment fan can be displayed on the display in real time. Alternatively, the fan frequency of the treatment fan can be sent to an external display device such as a worker's mobile phone, computer, etc., and the fan frequency of the treatment fan can be displayed on the external display device in real time.

[0070] Real-time display of the fan frequency of the treatment fan can facilitate the worker to determine whether the treatment fan fails when the indoor temperature is abnormal.

[0071] Please refer to Figure 5 In another embodiment, the dehumidifier is used to adjust the air humidity and air temperature in the target space 200. The dehumidifier comprises a fresh air inlet 10 and a fresh air outlet 20, a regeneration air inlet 50 and a regeneration air outlet 60, and a rotary wheel 30 and a treatment fan 40 arranged between the fresh air inlet 10 and the fresh air outlet 20, the rotary wheel 30 is provided with a desiccant, and the rotary wheel 30 comprises a drying area 31 and a regeneration area 32, the drying area 31 is arranged between the fresh air inlet 10 and the fresh air outlet 20, and the treatment fan 40 is arranged in the drying area 21; a temperature sensor 80 arranged in the target space 200 for measuring the space temperature of the target space 200; a control device 90 for obtaining the space temperature, determining whether the space temperature exceeds the first set temperature range for a set time, and adjusting the fan frequency of the treatment fan 40 when the space temperature exceeds the first set temperature range for a set time.

[0072] The number of temperature sensors 50 can be one or more. When the number of temperature sensors 80 is more than one, the multiple temperature sensors 80 can be arranged at multiple different positions in the target space 200, and each temperature sensor 80 measures the air temperature at the corresponding position. The control device obtains the average, minimum, maximum, median, etc. of the multiple air temperatures measured by all temperature sensors 80 as the space temperature of the target space 200.

[0073] The control device 90 can be a control chip in the dehumidifier or a whole structure including the control chip. The control device 90 can be in communication connection with the temperature sensor 80 and the treatment fan 40, for example, through a bus, radio, etc. to realize the communication connection, and to obtain the space temperature from the temperature sensor 80 through the established communication channel, and to control the adjustment of the fan frequency of the treatment fan 40.

[0074] Compared with the related art, in the dehumidifier provided in the embodiments of the present application, when it is determined that the space temperature exceeds the first set temperature range for a set time length, the control device 90 controls and adjusts the fan frequency of the treatment fan 40. The change of the fan frequency can change the air speed of the new air sent into the target space by the dehumidifier, and has an adjusting effect on the temperature in the target space 200. By setting the set time length, the fan frequency of the treatment fan 40 can be reduced from being frequently changed due to temperature fluctuation. Since the sudden change of the fan frequency can generate a large induced current, causing the energy consumption to increase, reducing the fan frequency of the treatment fan 40 from being frequently changed due to temperature fluctuation can effectively reduce the energy consumption in the temperature adjusting process.

[0075] In addition, in some embodiments of the present application, as shown in Figure 5 the dehumidifier can further include an air cooler 70. The air cooler 70 is arranged between the new air inlet 10 and the new air outlet 20. The control device 90 is further configured to determine whether the space temperature exceeds a second set temperature range, the second set temperature range being different from the first set temperature range. When the space temperature exceeds the second set temperature range, the electric proportional valve opening degree of the air cooler 70 is adjusted.

[0076] The control device 90 can be in communication connection with the air cooler 70, for example, the communication connection can be achieved through a bus, radio, etc., and the established communication channel is used to control and adjust the electric proportional valve opening degree of the air cooler 70.

[0077] When the control device 60 determines that the space temperature exceeds the second set temperature range, the electric proportional valve opening degree of the air cooler 70 is controlled and adjusted, which can also have an adjusting effect on the space temperature. In combination with the adjustment of the fan frequency according to the first set temperature range, the space temperature in the target space can be better adjusted.

[0078] In addition, in some embodiments of the present application, as shown in Figure 5 the dehumidifier can further include a return air inlet 80 and a return air outlet 90. The return air inlet 80 is communicated with the target space 200, and the return air outlet 90 is arranged between the treatment fan 40 and the new air inlet 10.

[0079] The return air inlet 80 is communicated with the target space 200, and the return air outlet 90 is arranged between the treatment fan 40 and the new air inlet 10. When the treatment fan 40 is running, air can be extracted from the target space 200 through the return air inlet 80, and return air is formed between the return air inlet 80 and the return air outlet 90. The dehumidifier sends new air into the target space 200 through the new air outlet 20, extracts air from the target space 200 through the return air inlet 80, forms return air, and forms a circulating air flow in the target space 200.

[0080] Adjusting the fan frequency of the treatment fan 40 can adjust the air volume of the return air drawn out of the target space by the treatment fan 40, so as to better regulate the space temperature of the target space 200.

[0081] Please refer to Figure 6 The embodiment of the application further provides a dehumidifier control device, which comprises: a communication module 601, the communication module 601 being configured to acquire a space temperature of a target space; a judgment module 602, the judgment module 602 being configured to judge whether the space temperature is kept within a first set temperature range for a set time length; and a control module 603, the control module 603 being configured to adjust a fan frequency of a treatment fan when the space temperature is kept within the first set temperature range for the set time length.

[0082] Compared with the related art, in the dehumidifier control device provided by the embodiment of the application, when the judgment module 602 judges that the space temperature exceeds the first set temperature range for the set time length, the control module 603 controls and adjusts the fan frequency of the treatment fan, the change of the fan frequency can change the air speed of the fresh air sent into the target space by the dehumidifier, and has a regulating effect on the temperature in the target space. By setting the set time length, the fan frequency of the treatment fan can be reduced from being frequently changed due to temperature fluctuation. Since a sudden change of the fan frequency can generate a large induced current, the energy consumption is increased. Reducing the fan frequency of the treatment fan from being frequently changed due to temperature fluctuation can effectively reduce the energy consumption in the temperature regulating process.

[0083] In addition, in other embodiments of the application, the judgment module 602 can be further configured to judge whether the space temperature exceeds a second set temperature range, the second set temperature range being different from the first set temperature range; and the control module 603 can be further configured to adjust an electric proportional valve opening degree of the cooling coil when the space temperature exceeds the second set temperature range.

[0084] In addition, in some other embodiments of the application, the communication module 601 can be further configured to send the fan frequency of the treatment fan to a display device for real-time display.
