[0063] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0064] In order to make the purpose, technical solutions and advantages of the present application clearer, exemplary embodiments will be described in detail here, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with the present application. On the contrary, they are merely examples of devices and implementation methods consistent with some aspects of the present application as detailed in the attached claims. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0065] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein, for example, can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a series of units, systems, products or devices are not necessarily limited to those units clearly listed, but may include units that are not clearly listed or inherent to these products or devices.

[0066] With the development of dehumidification equipment technology, dehumidifiers have important uses in conventional household, commercial or industrial fields. Whether household, commercial or industrial dehumidifiers, they all focus on human comfort or industrial equipment applicability, and their relative humidity range is generally controlled at 40%~60%. This is also the reason why many household, commercial and industrial dehumidifiers are mainly started and stopped according to the relative humidity of the environment of the dehumidified object.

[0067] However, when the dehumidification range of a conventional dehumidifier is 40% to 60%, its dehumidification range is only about 20%. Therefore, the dehumidification in a high dry-bulb temperature and low relative humidity environment is not taken into consideration when the dehumidifier is designed. The main low-temperature surface temperature of the dehumidified environment is smaller than the dry-bulb temperature of the dehumidified environment, resulting in the failure of the conventional dehumidifier to dehumidify in a high dry-bulb temperature and low relative humidity environment.

[0068] Therefore, combined with the above analysis, it can be seen that the relevant dehumidification technology has at least the problem of not being able to effectively dehumidify in a variety of different scenarios.

[0069] The dehumidification control method provided in the present application controls the start-up of the dehumidification device by judging based on the humidity environment and / or the ambient dew point temperature, and considers the ambient dew point temperature to start dehumidification, which is beneficial for the dehumidification device to achieve a stronger dehumidification capacity, so that dehumidification can be effectively performed in multiple different scenarios. In addition, the present application determines the target operating state of the dehumidification device and the target operating state of the fan, and dehumidifies in the corresponding target operating state, which can also enhance the dehumidification capacity of the dehumidification device, and can effectively and accurately dehumidify in a variety of different environmental scenarios, thereby solving the technical problem of how to effectively dehumidify in a variety of different scenarios.

[0070] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0071] In an exemplary embodiment, Figure 1 A schematic diagram of a dehumidification control method provided in this application, such as Figure 1 As shown, the present application can apply the dehumidification control method to a dehumidification system, which includes:

[0072] Cooling fan 110 , condenser 111 , expansion valve 112 , water collecting pan 113 , check valve 114 , drain pipe heating wire 115 , drain pipe temperature sensor 116 , drain pipe 117 , temperature and humidity sensor 118 , evaporation temperature sensor 119 , heater 120 , evaporator 121 , compressor 122 .

[0073] The condenser 111, the evaporator 121, the expansion valve 112 and the compressor 122 are sequentially connected to form a closed mechanical dehumidification system.

[0074] The condenser 111 and the evaporator 121 share the same cooling fan 110, and the air outlet of the evaporator 121 corresponds to the air inlet of the condenser 111; the heater 120 is located directly in front of the evaporator 121; the cooling fan 110 is located above the condenser 111, and the air outlet direction is obliquely upward; the temperature and humidity sensor 118 protects the air inlet side of the evaporator 121; the water receiving tray 113 is below the evaporator 121, and when the dehumidifier is in dehumidification mode, condensed water will be generated on the surface of the evaporator 121 and slide to the water receiving tray The bottom of the water receiving pan 113 has a certain inclination angle, and a water outlet is provided at the lowest point. The outside of the water outlet is connected with a check valve 114 and a drain pipe 117. The middle part of the drain pipe 117 is suspended on a hook at the bottom of the water receiving pan 113. The drain pipe 117 is designed with a return water bend structure, and the outlet of the drain pipe 117 is connected to the drain outlet on the dehumidifier casing; a drain pipe heating wire 115 is wound around the bottom of the return water bend of the drain pipe 117, and a drain pipe temperature sensor 116 is provided at the top of the return water bend of the drain pipe 117.

[0075] The function of the heater 120 is to heat the evaporator 121 for defrosting and thawing. The control method is that when the dehumidification mode is turned on, when the temperature value obtained by the evaporation temperature sensor 119 is lower than the defrost setting temperature, the dehumidification mode is exited and the heater 120 is turned on; when the temperature value obtained by the evaporation temperature sensor 119 is greater than the defrost setting temperature + °C or the defrost duration is greater than the set defrost off time, the heater 120 defrost mode is exited;

[0076] The function of the drain pipe heating wire 115 is to thaw the return bend of the drain pipe 117 to prevent the drain pipe 117 from freezing and affecting condensation drainage. The control method is that when the temperature obtained by the drain pipe temperature sensor 116 is less than -°C, the drain pipe heating wire 115 is turned on; when the drain pipe heating wire 115 is turned on, the drain pipe temperature sensor 116 detects a temperature greater than °C, and the drain pipe heating wire 115 is turned off;

[0077] The function of the water return bend of the drainage pipe 117 is to prevent the internal environment from being connected to the outside, causing the external humid air to flow back through the drainage pipe 117. The function of the check valve 114 is to prevent the water accumulated in the water return bend from being blown back into the dehumidifier when there is a strong air flow disturbance in the outside.

[0078] The dehumidification system provided in the embodiment of the present application has optional automatic dehumidification gear selection and dehumidification self-matching adaptation during dehumidification control. In the automatic dehumidification gear selection mode, it has six combination modes; in the dehumidification self-matching adaptation mode, the cooling fan 110 and the compressor 122 will perform PID control adjustment according to the deviation degree of the difference between the actual dry-bulb temperature and the actual dew point temperature and the deviation degree of the difference between the actual dew point temperature and the dew point set for dehumidification start-up.

[0079] Optionally, the dehumidification system provided in the embodiment of the present application further includes a control device. Figure 1 Not shown in FIG.

[0080] In an exemplary embodiment, Figure 2 Schematic diagram of the dehumidification control method provided in this application Figure 1 ,like Figure 2 As shown, the method is applied to a control device of a dehumidification system as an example for explanation. The method includes S201 to S202, wherein:

[0081] S201. When the ambient humidity and / or ambient dew point temperature of the current environment meet the dehumidification conditions, determine the target operating state of the dehumidification device and the target operating state of the fan according to the dry bulb temperature, the ambient dew point temperature and the preset startup dew point temperature.

[0082] Among them, the startup dew point temperature is used to indicate the startup of the dehumidification device.

[0083] It can be understood that the fan here can refer to Figure 1 The heat dissipation fan in the dehumidification system can be used to change the air flow rate in the dehumidification system, or can be used to achieve the effect of generating air flow disturbance. The dehumidification device may include Figure 1 The condenser, evaporator, compressor and other equipment in the room can achieve dehumidification effect by refrigeration and dehumidification when there is an evaporator.

[0084] The current environment may be the environment in which the dehumidification system is currently located, and may be the environment in which dehumidification is required. For example, the current environment may be the environment in a home when the dehumidification system is used as a household device. The dehumidification condition may be a startup condition set for humidity and / or dew point temperature, and the startup condition may refer to a condition for starting the dehumidification system.

[0085] Ambient humidity may refer to the humidity of the current environment, which may be the humidity detected by the humidity sensor. Ambient dew point temperature may refer to the dew point temperature of the current environment, which may be determined based on the ambient humidity and ambient temperature. Dry bulb temperature may refer to the value read on a dry bulb thermometer exposed to the air but not directly exposed to the sun, which is the temperature measured by the thermometer in ordinary air, that is, the temperature in the environment. The power-on dew point temperature may be a temperature set for power-on conditions.

[0086] It can be understood that the dry-bulb temperature and the ambient dew-point temperature may refer to dynamic temperatures that change with the environment, while the power-on dew-point temperature may refer to a static temperature that may be preset and will not change with the environment.

[0087] The target operating state may refer to the device operating in a certain target state to achieve the purpose of dehumidification. The target operating state may be different in different cycles, which may be determined according to the embodiments provided in the present application. By determining the target operating state, the effect of effective dehumidification in a variety of different scene environments can be achieved.

[0088] Exemplarily, the control device can obtain detection data such as ambient humidity and dry bulb temperature of the current environment through the temperature and humidity sensor 118. For example, after the dehumidification system is powered on, the temperature and humidity sensor 118 can detect the ambient humidity, dry bulb temperature and other data of the current environment in real time, and feed back to the control device in real time. And the control device can calculate and determine the ambient dew point temperature of the current environment through the ambient humidity and dry bulb temperature.

[0089] If the ambient humidity of the current environment meets the dehumidification conditions, the control device can determine the operating state of the dehumidification device based on the dry-bulb temperature, ambient dew point temperature and the preset power-on dew point temperature, that is, determine the target operating state of the dehumidification device; and determine the state in which the fan needs to operate, that is, determine the target operating state of the fan.

[0090] Alternatively, if the ambient dew point temperature of the current environment meets the dehumidification conditions, the control device can determine the target operating state of the dehumidification device and the target operating state of the fan according to the dry bulb temperature, the ambient dew point temperature and the preset startup dew point temperature.

[0091] Alternatively, if the current ambient humidity and ambient dew point temperature meet the dehumidification conditions, the control device can determine the target operating state of the dehumidification device and the target operating state of the fan based on the dry bulb temperature, ambient dew point temperature and preset startup dew point temperature.

[0092] In this way, through the above possible judgment conditions, it is possible to effectively judge whether dehumidification is needed in the dehumidification environment in various different scenarios, thereby enriching the dehumidification function of the dehumidification system, and then improving the capacity of the dehumidification system, effectively dehumidifying a variety of scenes, and enhancing the dehumidification effect.

[0093] S202: Control the dehumidification device and the fan to operate at a target operating state of the dehumidification device and a target operating state of the fan, respectively.

[0094] For example, the control device may control the dehumidification device to operate in the target operating state of the dehumidification device determined in S201. The control device may also control the fan to operate in the target operating state of the fan determined in S201.

[0095] For example, the operating state of the dehumidification device and the operating state of the fan correspond to different dehumidification gears. The control device can determine the dehumidification gear at which the dehumidification system should operate, and then determine the target operating state of the dehumidification device and the target operating state of the fan based on the operating state in the dehumidification gear.

[0096] For another example, the control device can control the start-up of the dehumidification device and the fan. When the dehumidification device and the fan are started, the operating state of the dehumidification device and the fan are adjusted according to the dry bulb temperature, the ambient dew point temperature and the start-up dew point temperature, so that both the dehumidification device and the fan can reach their corresponding target operating states.

[0097] It is understood that the target operating state may be a state setting such as speed, power, etc. For example, the target operating state of a dehumidifier may refer to the operating speed, operating power, etc. of the dehumidifier. The target operating state of a fan may refer to the operating speed, operating power, etc. of the fan. As an example, the target operating state of a dehumidifier is the operating power of the dehumidifier, while the target operating state of a fan may be the speed of the fan. The target operating state represents an operating parameter during the operation of a device.

[0098] In this embodiment, the dehumidification control method provided by the present application controls the start-up of the dehumidification device by making judgments based on the humidity environment and / or the ambient dew point temperature. For example, if the ambient humidity and / or the ambient dew point temperature of the current environment meet the dehumidification conditions, the target operating state of the dehumidification device and the target operating state of the fan can be determined, and the dehumidification device and the fan can be controlled to operate in the corresponding target operating states respectively. In this way, the present application utilizes multiple environmental factors for judgment and can effectively dehumidify multiple different scenes. Moreover, the present application can effectively and accurately dehumidify in multiple different environmental scenes by determining the target operating state of the dehumidification device and the target operating state of the fan. Therefore, the present application can achieve the effect of effective dehumidification in multiple different scene environments through the above-mentioned control method.

[0099] In an exemplary embodiment, the dehumidification condition includes that the ambient humidity is greater than the preset startup humidity and the ambient dew point temperature is greater than the startup dew point temperature. In this way, the dehumidification condition provided by the present application not only considers the conventional ambient humidity as the startup condition, but also considers the dew point temperature as the dehumidification condition, which is more suitable for dehumidification in a variety of different scenarios and enhances the dehumidification effect of the dehumidification system.

[0100] In an exemplary embodiment, the method further comprises:

[0101] When the ambient humidity is lower than the preset shutdown humidity and the ambient dew point temperature is higher than the preset shutdown dew point temperature, the dehumidification device and the fan are controlled to shut down.

[0102] The shutdown humidity refers to the humidity set for shutting down the dehumidification system, and the shutdown dew point temperature refers to the dew point temperature set for shutting down the dehumidification system.

[0103] For example, under the above-mentioned shutdown conditions, if it is proved that the humidity of the environment meets the humidity requirements, the dehumidification system can be shut down, thereby ensuring the correctness of the dehumidification. In addition, shutting down the dehumidification based on the above-mentioned shutdown conditions can be used in a variety of scenarios requiring dehumidification, further enhancing the dehumidification effect in a variety of different scenarios.

[0104] Optionally, the method further comprises:

[0105] If the operation duration of the dehumidification device and the fan is greater than the preset dehumidification shutdown time, the dehumidification device and the fan are controlled to shut down.

[0106] For example, when the dehumidification duration is greater than the set dehumidification shutdown time, the dehumidification mode can be turned off. The dehumidification shutdown time condition is a supplement to the dehumidification shutdown logic condition. It can prevent the dehumidifier from being ineffective for a long time in extremely harsh situations or when the temperature and humidity sensor 118 obtains incorrect values.

[0107] In an exemplary embodiment, Figure 3 Schematic diagram of the dehumidification control method provided in this application Figure 2 ,like Figure 3 As shown, in this embodiment Figure 2 Based on the embodiment, the step S201 is exemplarily described. In the step S201, the target operating state of the dehumidification device and the target operating state of the fan are determined according to the dry bulb temperature, the ambient dew point temperature and the preset startup dew point temperature, which may specifically include S301 and S302, wherein:

[0108] S301, obtaining a first temperature deviation between a dry-bulb temperature and an ambient dew-point temperature, and a second temperature deviation between the ambient dew-point temperature and a startup dew-point temperature;

[0109] S302: Determine a target operating state of the dehumidification device and a target operating state of the fan based on the first temperature deviation and the second temperature deviation.

[0110] Among them, the first temperature deviation may refer to the difference between the dry-bulb temperature and the ambient dew-point temperature. The first temperature deviation may be a signed number or an unsigned number. The second temperature deviation may refer to the difference between the ambient dew-point temperature and the power-on dew-point temperature. Similarly, the second temperature deviation may be a signed number or an unsigned number. As an example, the first temperature deviation is an unsigned number, and the second temperature deviation is a signed number. That is to say, under normal circumstances, when the dehumidification system is turned on, the dry-bulb temperature is greater than the ambient dew-point temperature, and the ambient dew-point temperature may be greater than the power-on dew-point temperature, and the ambient dew-point temperature may also be less than the power-on dew-point temperature.

[0111] For example, the control device may determine the first temperature deviation by comparing the dry bulb temperature with the ambient dew point temperature, and may also determine the ambient dew point temperature and the startup dew point temperature by comparing the ambient dew point temperature with the startup dew point temperature.

[0112] For example, the control device can determine the dehumidification gear that needs to be turned on for the dehumidification system based on the first temperature deviation and the second temperature deviation, and determine the corresponding target operating state of the dehumidification device and the target operating state of the fan according to the dehumidification gear.

[0113] For another example, the control device may determine the target operating state of the fan according to the first temperature deviation, and determine the target operating state of the dehumidification device according to the second temperature deviation.

[0114] In this embodiment, the first temperature deviation is determined by the dry-bulb temperature and the ambient dew-point temperature, and the second temperature deviation is determined by the ambient dew-point temperature and the power-on dew-point temperature. The target operating state of the dehumidification device and the target operating state of the fan can be effectively and accurately determined through the first temperature deviation and the second temperature deviation, so that the dehumidification system can enhance the dehumidification effect in different environmental scenarios.

[0115] In an exemplary embodiment, Figure 4 Schematic diagram of the dehumidification control method provided in this application Figure 3 ,like Figure 4 As shown, in this embodiment Figure 3 Based on the embodiment, the step S302 is exemplarily described. In the step S302, based on the first temperature deviation and the second temperature deviation, the target operating state of the dehumidification device and the target operating state of the fan are determined, which may specifically include: S401 to S404, wherein:

[0116] S401. Determine a target operating gear from a plurality of preset operating gears according to a first temperature deviation and a second temperature deviation; each preset operating gear corresponds to a different operating state of the dehumidifier and an operating state of the fan.

[0117] Among them, the target operating state of the dehumidification device is: the operating state of the dehumidification device corresponding to the target operating gear.

[0118] The preset operating gear may be a pre-set dehumidification gear for the dehumidification system, for example, it may be a gear set when the dehumidification system leaves the factory. The target operating gear may refer to the dehumidification gear that the dehumidification system needs to operate at, and under the target operating gear, the dehumidification demand under the current environment can be met. For each preset operating gear, the preset operating gear corresponds to the operating status of the dehumidification device and the operating status of the fan.

[0119] For example, the control device can determine the target operating gear at which the dehumidification system should operate based on the first temperature deviation and the second temperature deviation, and can start the dehumidification system at the target operating gear to perform dehumidification. In this way, the target operating state of the dehumidification device is also the target operating state of the dehumidification device, so that the target operating state of the dehumidification device can be effectively determined.

[0120] In this embodiment, the target operating gear is determined from multiple preset operating gears based on the first temperature deviation and the second temperature deviation, and the target operating state of the dehumidification device can be effectively and accurately determined in the preset operating state, which can meet the dehumidification needs in the current environment, thereby enhancing the dehumidification effect of multiple different environmental scenes, effectively dehumidifying different environmental scenes, and expanding the dehumidification capacity for different environments.

[0121] S402. When the second temperature deviation indicates that the ambient dew point temperature is greater than the startup dew point temperature, control the dehumidification device to operate in the first operating state of the dehumidification device; wherein the first operating state is used to indicate that the dehumidification device operates at a preset maximum speed.

[0122] The first operating state of the dehumidifier may refer to one of the operating states of the dehumidifier. The preset maximum speed may be a maximum speed preset for the dehumidifier, for example, the preset maximum speed may be 100% speed.

[0123] Exemplarily, if the control device detects that the ambient dew point temperature is greater than the startup dew point temperature, the control device can control the dehumidification device to operate in the first operating state of the dehumidification device, that is, control the dehumidification device to operate at a preset maximum speed, thereby ensuring that dehumidification is effectively performed when the ambient dew point temperature is greater than the startup dew point temperature.

[0124] In this embodiment, when the ambient dew point temperature represented by the second temperature deviation is greater than the startup dew point temperature, the dehumidification device is controlled to operate in the first operating state of the dehumidification device, which can enhance the dehumidification capacity of the dehumidification system in different scenarios, so that dehumidification can be effectively performed in different scenarios.

[0125] S403. When the second temperature deviation indicates that the ambient dew point temperature is less than the power-on dew point temperature, control the dehumidification device to operate in the second operating state of the dehumidification device; wherein the second operating state is used to indicate that the dehumidification device operates at a speed lower than a preset maximum speed.

[0126] The second operating state of the dehumidifier may refer to one of the operating states of the dehumidifier. The second operating state may be a state of operation lower than a preset maximum speed. For example, when the preset maximum speed is 100%, the second operating state may be 80% speed, or 70% speed, etc.

[0127] Exemplarily, if the control device detects that the ambient dew point temperature is lower than the power-on dew point temperature, the control device may control the dehumidification device to operate in the second operating state of the dehumidification device, that is, control the dehumidification device to operate at a speed lower than the preset maximum speed, thereby ensuring that dehumidification is effectively performed when the ambient dew point temperature is lower than the power-on dew point temperature.

[0128] In this embodiment, when the ambient dew point temperature represented by the second temperature deviation is less than the startup dew point temperature, the dehumidification device is controlled to operate in the second operating state of the dehumidification device, which can enhance the dehumidification capacity of the dehumidification system in different scenarios, so that dehumidification can be effectively performed in different scenarios.

[0129] S404, determining a target deviation interval corresponding to the first temperature deviation; wherein different deviation intervals correspond to different operating states of the fan.

[0130] The target operating state of the fan is the operating state of the fan within the target deviation range.

[0131] The target deviation interval may refer to an interval in which the value of the first temperature deviation is located, and the target deviation interval may be a preset interval.

[0132] Exemplarily, the target operating state of the fan can be determined based on the fact that different pre-set deviation intervals correspond to different operating states of the fan. The control device can determine that the target operating state of the fan is the operating state of the fan corresponding to the target deviation interval in which the first temperature deviation is located.

[0133] For example, when the difference between the dry bulb temperature and the ambient dew point temperature is less than 10°C, the fan can run at the maximum speed; when the difference between the dry bulb temperature and the ambient dew point temperature is between 10°C and 15°C, the fan can run at a medium speed; when the difference between the dry bulb temperature and the ambient dew point temperature is greater than 15°C, the fan can run at a low speed. Among them, the maximum speed, medium speed and low speed can all be pre-set speeds, and the above three can be relative speeds.

[0134] In this embodiment, by determining the target deviation interval corresponding to the first temperature deviation, the target operating state of the fan can be effectively and accurately determined, thereby ensuring the dehumidification effect in different environmental scenarios.

[0135] In some specific embodiments, Figure 5 Schematic diagram of the dehumidification control method provided in this application Figure 4 ,like Figure 5 As shown, in this embodiment Figure 2 Based on the embodiment, the dehumidification control method is exemplarily described, and the method may specifically include: S501 to S509, wherein:

[0142] S507, dehumidifier mode selection: After the dehumidifier is turned on, it automatically enters the dehumidification mode selection; for example, the dehumidification mode includes:

[0143] Mode 1: When the difference between the dry bulb temperature and the dew point temperature of the dehumidified environment is less than 10°C, and the dew point temperature is greater than the startup dew point temperature, the compressor runs at 100% full speed and the circulation fan runs at 100% speed.

[0144] Mode 2: When the difference between the dry bulb temperature of the dehumidified environment and the dew point temperature of the environment is 10℃~15℃, and the dew point temperature is greater than the startup dew point temperature, the compressor runs at 100% full speed and the circulation fan runs at 80% speed;

[0145] Mode 3: When the difference between the dry bulb temperature of the dehumidified environment and the dew point temperature of the environment is greater than 15°C, and the dew point temperature is greater than the startup dew point temperature, the compressor runs at 100% full speed and the circulation fan runs at 60% speed;

[0146] Mode 4: When the difference between the dry bulb temperature of the dehumidified environment and the dew point temperature is less than 10°C, and the dew point temperature is less than the startup dew point temperature, the compressor runs at 70% of the full speed and the circulation fan runs at 80% of the speed;

[0147] Mode 5: When the difference between the dry bulb temperature of the dehumidified environment and the dew point temperature of the environment is 10℃~15℃, and the dew point temperature is less than the startup dew point temperature, the compressor runs at 70% of the full speed and the circulation fan runs at 60% of the speed;

[0148] Mode 6: When the difference between the dry bulb temperature of the dehumidified environment and the ambient dew point temperature is greater than 15°C and the dew point temperature is less than the startup dew point temperature, the compressor runs at 70% of the full speed and the circulation fan runs at 40% of the speed.

[0149] It should be noted that the dehumidification mode can also be called the dehumidification gear.

[0150] Among them, the specific forms of the dehumidification mode can be shown in Table 1 and Table 2.

[0155] S508: Whether the dehumidification shut-off condition is met.

[0156] S509, exit the dehumidification mode.

[0157] Among them, during the dehumidification startup process, the dehumidification shutdown conditions are confirmed at any time. The dehumidification shutdown conditions include logical condition judgment and time condition judgment. The dehumidification shutdown logical condition is: in the dehumidification startup mode, when the ambient humidity is less than the dehumidification shutdown set humidity (shutdown humidity) and the ambient dew point temperature is greater than the dehumidification shutdown set dew point (shutdown dew point temperature), the dehumidification mode is turned off; the dehumidification shutdown time condition is: in the dehumidification startup mode, it is detected that the dehumidification duration is greater than the set dehumidification shutdown time, and the dehumidification mode is turned off; the dehumidification shutdown time condition is a supplement to the dehumidification shutdown logical condition, which is for extreme conditions or when the value of the temperature and humidity sensor 118 is wrong, to avoid the dehumidifier from being ineffective for a long time.

[0158] In this embodiment, the condensation problem on a surface with a constant dew point temperature can be solved through the above-mentioned control method; a lower dehumidification surface temperature can be obtained to ensure the dehumidification capacity in a high dry-bulb temperature and low relative humidity environment, and to achieve dehumidification under extremely large dry-bulb dew point temperature difference; the optimal combination of the difference between the dehumidification surface temperature and the dew point temperature of the dehumidified air and the circulating air volume can be achieved, and the humidity fluctuation of the dehumidified environment can be reduced. By combining rapid dehumidification with slow dehumidification, fluctuations in the relative humidity of the dehumidified environment caused by the start and stop of the dehumidifier can be avoided.

[0159] In an exemplary embodiment, Figure 6 Schematic diagram of the dehumidification control method provided in this application Figure 5 ,like Figure 6 As shown, in this embodiment Figure 2 Based on the embodiment, the step S201 is exemplarily described. In the step S201, the target operating state of the dehumidification device and the target operating state of the fan are determined according to the dry bulb temperature, the ambient dew point temperature and the preset startup dew point temperature. Specifically, it may include S601 to S604, wherein:

[0160] S601, control the dehumidification device to operate in a preset initial operating state of the dehumidification device, and control the fan to operate in a preset initial operating state of the fan.

[0161] S602: When the dehumidification device and the fan are running, determine a first temperature deviation between the dry-bulb temperature and the ambient humidity, and a second temperature deviation between the ambient dew point temperature and the startup dew point temperature.

[0162] S603: Determine a target operating state of the fan based on the first temperature deviation.

[0163] S604: Determine a target operating state of the dehumidification device based on the second temperature deviation.

[0164] The initial operation state may refer to a state when the operation is started, and the initial operation state may be a preset start state.

[0165] Exemplarily, when it is determined that the ambient humidity and / or ambient dew point temperature of the current environment meet the dehumidification conditions, the control device can control the dehumidification device and the fan to operate in a corresponding preset initial operating state, and after the above-mentioned device is turned on, the first temperature deviation between the dry bulb temperature and the ambient humidity can be determined, and the target operating state of the fan can be determined based on the first temperature deviation, and the fan can be controlled to the target operating state of the fan. The control device can also determine the second temperature deviation between the ambient dew point temperature and the startup dew point temperature, and the target operating state of the dehumidification device can be determined based on the second temperature deviation.

[0166] It can be understood that the target operating state can also be the initial operating state, that is, the operating states of the above two devices do not need to be changed at this time. If the target operating state is not the initial operating state, it means that the operating states of the two devices have changed.

[0167] In this embodiment, through the method of S601 to S604, the target operating state of the fan and the target operating state of the dehumidification device can be effectively and accurately determined, so that the dehumidification effect of the dehumidification system in different environmental scenarios can be enhanced.

[0168] Optionally, in step S201, determining the target operating state of the dehumidification device according to the dry-bulb temperature, the ambient dew point temperature and the preset startup dew point temperature may further include:

[0170] When the dehumidifier and the fan are running, determine the humidity deviation between the ambient humidity and the preset start-up humidity;

[0171] Based on the humidity deviation, a target operating state of the dehumidification device is determined.

[0172] The startup humidity can be the humidity set for the dehumidification system when it is started. The humidity deviation refers to the difference between the ambient humidity and the startup humidity. The humidity deviation can be signed data or unsigned data.

[0173] Exemplarily, when it is determined that the ambient humidity and / or ambient dew point temperature of the current environment meet the dehumidification conditions, the control device can control the dehumidification device and the fan to operate in a corresponding preset initial operating state, and after the above-mentioned device is turned on, the control device can also determine the target operating state of the dehumidification device based on the humidity deviation between the ambient humidity and the startup humidity, so as to achieve better control of the operating state of the dehumidification device, thereby better controlling the dehumidification device, and further facilitating better dehumidification of the current environment, thereby better achieving the dehumidification effect for different environmental scenarios.

The dehumidification device performs PID forward control adjustment according to the second temperature deviation between the ambient dew point temperature and the startup dew point temperature. When the second temperature deviation indicates that the ambient dew point temperature is higher than the startup dew point temperature, or the ambient humidity is higher than the startup humidity, the dehumidification device will perform frequency increase adjustment, and its speed adjustment range is 50%~100%. The default dehumidification card dew point temperature is 18℃, and the dehumidification device speed control PID control is position incremental PID. For example, if the current fan speed is 80%, and the current actual dew point temperature of the environment is 19℃, the dehumidification device speed in the next cycle will be 80%+increment.

[0184] S709, the circulation fan speed is turned on at 100%. After dehumidification is turned on, the circulation fan is turned on at 100% speed.

[0186] S711, fan speed reduction. The circulating fan is PID negatively controlled and adjusted according to the first temperature deviation between the actual dry-bulb temperature and the ambient dew point temperature. When the first temperature deviation is greater than the preset temperature difference threshold, the dehumidification circulating fan will be adjusted to reduce the speed, and the speed adjustment range is 50%~100%. The default temperature difference threshold is set to 10°C, and the fan speed control PID is position incremental PID. For example, if the current fan speed is 70% and the current first temperature deviation is 9°C, the fan speed in the next cycle will be 70%+increment.
