[0063] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0064] To make the objectives, technical solutions, and advantages of this application clearer, exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description relating to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatus and implementations consistent with some aspects of this application as detailed in the appended claims. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0065] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, including a series of units, systems, products, or devices is not necessarily limited to those explicitly listed, but may include units not explicitly listed or inherent to those products or devices.

[0066] With the development of dehumidification equipment technology, dehumidifiers have become increasingly important in conventional household, commercial, and industrial applications. Whether household, commercial, or industrial, dehumidifiers are designed to address human comfort or suitability for industrial equipment, typically maintaining a relative humidity range of 40% to 60%. This is why many household, commercial, and industrial dehumidifiers control their operation based on the relative humidity of the environment being dehumidified.

[0067] However, while conventional dehumidifiers have a dehumidification range of 40% to 60%, this dehumidifier only has a dehumidification range of about 20%. Therefore, the dehumidifier was not designed to take into account dehumidification in environments with high dry-bulb temperature and low relative humidity. The main low-temperature surface temperature for dehumidification is close to the dry-bulb temperature of the environment being dehumidified, which causes conventional dehumidifiers to fail in environments with high dry-bulb temperature and low relative humidity.

[0068] Therefore, based on the above analysis, it can be concluded that, among the relevant dehumidification technologies, there is at least one problem: they cannot effectively dehumidify in many different scenarios.

[0069] The dehumidification control method provided in this application controls the start-up of the dehumidification device based on the humidity environment and / or the ambient dew point temperature. Taking the ambient dew point temperature into account when starting dehumidification helps the dehumidification device achieve stronger dehumidification capabilities, thus effectively dehumidifying multiple different scenarios. Furthermore, by determining the target operating state of the dehumidification device and the target operating state of the fan, and performing dehumidification according to the corresponding target operating state, this application can also enhance the dehumidification capability of the dehumidification device, effectively and accurately dehumidifying in various different environmental scenarios, thus solving the technical problem of how to effectively dehumidify in multiple different scenarios.

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

[0071] In one exemplary embodiment, Figure 1 This is a schematic diagram of a scenario for the dehumidification control method provided in this application, such as... Figure 1 As shown, this application can apply the dehumidification control method to a dehumidification system, which includes:

[0072] Cooling fan 110, condenser 111, expansion valve 112, drip tray 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, evaporator 121, expansion valve 112 and compressor 122 are connected in sequence to form a closed mechanical dehumidification system.

[0074] Condenser 111 and evaporator 121 share the same cooling fan 110. The air outlet of evaporator 121 corresponds to part of the air inlet of condenser 111. Heater 120 is located directly in front of evaporator 121. Cooling fan 110 is located above condenser 111, with the air outlet direction diagonally upward. Temperature and humidity sensor 118 maintains the air inlet side of evaporator 121. Drain tray 113 is located below evaporator 121. During dehumidification mode, condensation will form on the surface of evaporator 121 and slide down into the drain tray. The water receiving tray 113 has a certain angle at the bottom and a water outlet at the lowest point. The water outlet is connected to the check valve 114 and the drain pipe 117. The middle part of the drain pipe 117 is suspended on the hook at the bottom of the water receiving tray 113. The drain pipe 117 has a water return bend structure design. The outlet of the drain pipe 117 is connected to the drain outlet on the dehumidifier casing. The bottom of the water return bend of the drain pipe 117 is wrapped with a drain pipe heating wire 115, and the top of the water return bend of the drain pipe 117 is equipped with a drain pipe temperature sensor 116.

[0075] The heater 120 is used for defrosting and defrosting heating of the evaporator 121. Its control method is as follows: when the dehumidification mode is on, when the temperature value obtained by the evaporation temperature sensor 119 is lower than the defrosting set temperature, the dehumidification mode is exited and the heater 120 is turned on; when the heater 120 is on, when the temperature value obtained by the evaporation temperature sensor 119 is greater than the defrosting set temperature + ℃ or the defrosting duration is greater than the set defrosting off time, the defrosting mode of the heater 120 is exited.

[0076] The function of the drain pipe heating wire 115 is to defrost the return water bend of the drain pipe 117, so as to prevent the drain pipe 117 from freezing and affecting condensation drainage. The control method is as follows: when the temperature detected by the drain pipe temperature sensor 116 is less than -℃, the drain pipe heating wire 115 is turned on; when the drain pipe heating wire 115 is turned on, if the temperature detected by the drain pipe temperature sensor 116 is greater than ℃, the drain pipe heating wire 115 is turned off.

[0077] The function of the drain pipe 117 is to prevent the internal environment from connecting with the outside, causing the outside humid air to backflow through the drain pipe 117. The function of the check valve 114 is to prevent the water accumulated in the drain pipe from being blown back into the dehumidifier when there is strong airflow disturbance outside.

[0078] The dehumidification system provided in this application embodiment has the option of automatic dehumidification level selection and dehumidification self-matching adaptation during dehumidification control. In the automatic dehumidification level 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 of the actual dry bulb temperature from the actual dew point temperature and the deviation of the actual dew point temperature from the dehumidification start setting dew point.

[0079] Optionally, the dehumidification system provided in this application embodiment further includes a control device, which in... Figure 2 Not shown in the image.

[0080] In one exemplary embodiment, Figure 1 Flowchart of the dehumidification control method provided in this application Figure 2 ,like Figure 1 As shown, taking the application of this method to a control device in a dehumidification system as an example, the method includes steps S201 to S202, wherein:

[0081] S201. When the current ambient humidity and / or ambient dew point temperature meet the dehumidification conditions, 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 start-up dew point temperature.

[0082] The start-up dew point temperature is used to indicate when the dehumidifier is turned on.

[0083] It is understandable that the wind turbine here could refer to... Figure 1 The cooling fan in the dehumidification system can be used to change the airflow velocity or to generate airflow disturbance. The dehumidification device may include... Figure 3 Equipment such as condensers, evaporators, and compressors in a refrigerator can achieve dehumidification through refrigeration when they have an evaporator.

[0084] The current environment can refer to the environment in which the dehumidification system is currently located, or the environment in which dehumidification is required. For example, the current environment could be the indoor environment of a home when the dehumidification system is used as a household appliance. The dehumidification conditions can be the start-up conditions set for humidity and / or dew point temperature; the start-up conditions refer to the conditions under which the dehumidification system is activated.

[0085] Ambient humidity can refer to the humidity of the current environment, which can be detected by a humidity sensor. Ambient dew point temperature can refer to the dew point temperature of the current environment, which can be determined based on ambient humidity and ambient temperature. Dry bulb temperature refers to the value read from a dry bulb thermometer exposed to air but not directly exposed to sunlight; it is the temperature measured by the thermometer in ordinary air, i.e., the ambient temperature. Start-up dew point temperature can be a temperature set for start-up conditions.

[0086] It is understandable that dry bulb temperature and ambient dew point temperature refer to dynamic temperatures that change with the environment, while the start-up dew point temperature refers to static temperatures that can be preset and do not change with the environment.

[0087] The target operating state refers to the device operating in a specific state to achieve dehumidification. The target operating state can be different in different cycles, and can be determined according to the embodiments provided in this application. By determining the target operating state, effective dehumidification can be achieved in various different scenarios.

[0088] For example, the control device can acquire ambient humidity, dry-bulb temperature, and other detection data of the current environment through the temperature and humidity sensor 118. For instance, 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 them back to the control device in real time. Furthermore, the control device can calculate and determine the ambient dew point temperature of the current environment based on the ambient humidity and dry-bulb temperature.

[0089] If the current ambient humidity meets the dehumidification requirements, the control equipment can determine the operating state of the dehumidification device based on the dry bulb temperature, ambient dew point temperature, and preset start-up dew point temperature; that is, determine the target operating state of the dehumidification device; and determine the operating state of the fan; that is, determine the target operating state of the fan.

[0090] Alternatively, if the ambient dew point temperature meets the dehumidification requirements, the control equipment can determine the target operating state of the dehumidification device and the target operating state of the fan based on the dry bulb temperature, the ambient dew point temperature, and the preset start-up dew point temperature.

[0091] Alternatively, if the current ambient humidity and dew point temperature meet the dehumidification requirements, the control equipment 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 the preset start-up dew point temperature.

[0092] Thus, by using the above possible judgment conditions, it is possible to effectively determine whether dehumidification is needed in various dehumidification environments, thereby enriching the dehumidification function of the dehumidification system, improving the system's capabilities, effectively dehumidifying various scenarios, and enhancing the dehumidification effect.

[0093] S202. Control the dehumidification device and the fan to operate at their respective target operating states.

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

[0095] For example, the operating status of the dehumidifier and the operating status of the fan correspond to different dehumidification levels. The control equipment can determine the dehumidification level that the dehumidification system should operate at, and then determine the target operating status of the dehumidifier and the target operating status of the fan based on the operating status in the dehumidification level.

[0096] For example, the control equipment can control the dehumidifier and the fan to start. When the dehumidifier and the fan start, the operating status of the dehumidifier and the fan can be adjusted according to the dry bulb temperature, the ambient dew point temperature and the start-up dew point temperature, so that the dehumidifier and the fan can reach their corresponding target operating status.

[0097] It's understandable that the target operating state can be a setting such as speed or power. For example, the target operating state of a dehumidifier could refer to its operating speed or power. Similarly, the target operating state of a fan could refer to its operating speed or power. As an example, the target operating state of a dehumidifier is its operating power, while the target operating state of a fan could be its speed. The target operating state characterizes the operating parameters of a device during operation.

[0098] In this embodiment, the dehumidification control method provided by this application controls the start-up of the dehumidification device based on the humidity environment and / or the ambient dew point temperature. For example, if the current ambient humidity and / or ambient dew point temperature 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. In this way, this application can effectively dehumidify multiple different scenarios by using multiple environmental factors for judgment. Furthermore, by determining the target operating state of the dehumidification device and the target operating state of the fan, this application can effectively and accurately dehumidify multiple different environmental scenarios. Thus, through the above control method, this application can achieve the effect of effective dehumidification in multiple different scenario environments.

[0099] In one exemplary embodiment, the dehumidification conditions include an ambient humidity greater than a preset start-up humidity and an ambient dew point temperature greater than the start-up dew point temperature. Thus, the dehumidification conditions provided in this application not only consider conventional ambient humidity as a start-up condition but also dew point temperature as a dehumidification condition, making it more suitable for dehumidification in various scenarios and enhancing the dehumidification effect of the dehumidification system.

[0100] In one exemplary embodiment, the method further includes:

[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 fan will be shut down.

[0102] Among them, the shutdown humidity refers to the humidity set when the dehumidification system is turned off, and the shutdown dew point temperature refers to the dew point temperature set when the dehumidification system is turned off.

[0103] For example, under the above shutdown conditions, it is proven that the humidity of the environment meets the humidity requirements, and the dehumidification system can be turned off, thereby ensuring the correctness of dehumidification. Furthermore, dehumidification can be turned off based on the above shutdown conditions, which can be used in various scenarios that require dehumidification, further enhancing the dehumidification effect in various different scenarios.

[0104] Optionally, the method further includes:

[0105] If the dehumidifier and fan operate for a longer period than the preset dehumidification shutdown time, then the dehumidifier and fan will be shut down.

[0106] For example, the dehumidification mode can be turned off when the dehumidification duration exceeds the set dehumidification off time. The dehumidification off time condition is a supplement and improvement to the dehumidification off logic condition, which can prevent the dehumidifier from dehumidifying ineffectively for a long time in extreme conditions or when the temperature and humidity sensor 118 values ​​are incorrect.

[0107] In one exemplary embodiment, Figure 2 Flowchart of the dehumidification control method provided in this application Figure 3 ,like Figure 4 As shown, in this embodiment... Figure 3 Based on the embodiments, the steps of S201 are described by example. In step S201, the target operating state of the dehumidifier and the target operating state of the fan are determined according to the dry bulb temperature, the ambient dew point temperature, and the preset start-up dew point temperature. Specifically, this may include S301 and S302, wherein:

[0108] S301. Obtain the first temperature deviation between the dry bulb temperature and the ambient dew point temperature, and the second temperature deviation between the ambient dew point temperature and the start-up dew point temperature.

[0109] S302. Based on the first temperature deviation and the second temperature deviation, determine the target operating state of the dehumidification device and the target operating state of the fan.

[0110] The first temperature deviation refers to the difference between the dry-bulb temperature and the ambient dew point temperature. This first temperature deviation can be a signed or unsigned number. The second temperature deviation refers to the difference between the ambient dew point temperature and the start-up dew point temperature. Similarly, the second temperature deviation can be a signed or 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, generally, when the dehumidification system is turned on, the dry-bulb temperature is higher than the ambient dew point temperature, while the ambient dew point temperature may be higher than the start-up dew point temperature, or it may be lower than the start-up dew point temperature.

[0111] For example, the control device can determine a first temperature deviation by comparing the dry-bulb temperature with the ambient dew point temperature, and can also determine the ambient dew point temperature and the start-up dew point temperature by comparing the ambient dew point temperature with the start-up dew point temperature. Furthermore, the control device can be based on...

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

[0113] For example, the control equipment can determine the target operating state of the fan based on the first temperature deviation, and determine the target operating state of the dehumidification device based on the second temperature deviation.

[0114] In this embodiment, a first temperature deviation is determined by comparing the dry bulb temperature with the ambient dew point temperature, and a second temperature deviation is determined by comparing the ambient dew point temperature with the start-up dew point temperature. By using the first and second temperature deviations, the target operating state of the dehumidifier and the target operating state of the fan can be effectively and accurately determined, thereby enhancing the dehumidification effect of the dehumidification system for different environmental scenarios.

[0115] In one exemplary embodiment, Figure 4 Flowchart of the dehumidification control method provided in this application Figure 3 ,like Figure 5 As shown, in this embodiment... Figure 4 Based on the embodiments, step S302 is described by example. In step S302, the target operating state of the dehumidifier and the target operating state of the fan are determined based on the first temperature deviation and the second temperature deviation. Specifically, this may include steps S401 to S404, wherein:

[0116] S401. Based on the first temperature deviation and the second temperature deviation, determine the target operating level from multiple preset operating levels; each preset operating level corresponds to a different operating state of the dehumidification device and the operating state of the fan.

[0117] The target operating state of the dehumidifier is the operating state of the dehumidifier corresponding to the target operating level.

[0118] The preset operating level can be a dehumidification level that has been pre-set for the dehumidification system, for example, a level that is set at the factory. The target operating level refers to the dehumidification level at which the dehumidification system needs to operate, at which the dehumidification requirements of the current environment can be met. For each preset operating level, there is a corresponding operating status of the dehumidification device and the fan.

[0119] For example, the control device can determine the target operating level of the dehumidification system based on a first temperature deviation and a second temperature deviation, and can start the dehumidification system at the target operating level for dehumidification. In this way, the target operating state of the dehumidification device is also the target operating state of the dehumidification device, thereby effectively determining the target operating state of the dehumidification device.

[0120] In this embodiment, based on the first temperature deviation and the second temperature deviation, the target operating level is determined from multiple preset operating levels. This can effectively and accurately determine the target operating state of the dehumidifier within the preset operating state, thereby meeting the dehumidification needs of the current environment. This enhances the dehumidification effect in multiple different environmental scenarios, effectively dehumidifies different environmental scenarios, and expands the dehumidification capacity for different environments.

[0121] S402, when the ambient dew point temperature, which is characterized by the second temperature deviation, is greater than the start-up dew point temperature, the dehumidifier is controlled to operate in the first operating state of the dehumidifier; wherein, the first operating state is used to indicate that the dehumidifier operates at a preset maximum speed.

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

[0123] For example, if the control device detects that the ambient dew point temperature is higher than the start-up dew point temperature, the control device can control the dehumidifier to operate in the first operating state of the dehumidifier, that is, control the dehumidifier to operate at the preset maximum speed, so as to ensure effective dehumidification when the ambient dew point temperature is higher than the start-up dew point temperature.

[0124] In this embodiment, when the ambient dew point temperature is greater than the start-up dew point temperature, the dehumidification device is controlled to operate in the first operating state of the dehumidification device by the second temperature deviation characterizing the ambient dew point temperature. This can enhance the dehumidification capability of the dehumidification system in different scenarios, so that it can effectively dehumidify in different scenarios.

[0125] S403, when the ambient dew point temperature, which is characterized by the second temperature deviation, is lower than the start-up dew point temperature, the dehumidifier is controlled to operate in the second operating state of the dehumidifier; wherein, the second operating state is used to indicate that the dehumidifier operates at a speed lower than the preset maximum speed.

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

[0127] For example, if the control device detects that the ambient dew point temperature is lower than the start-up dew point temperature, the control device can control the dehumidifier to operate in the second operating state of the dehumidifier, that is, control the dehumidifier to operate at a speed lower than the preset maximum speed, so as to ensure effective dehumidification when the ambient dew point temperature is lower than the start-up dew point temperature.

[0128] In this embodiment, when the ambient dew point temperature is lower than the start-up dew point temperature, the dehumidification device is controlled to operate in the second operating state of the dehumidification device by the second temperature deviation characterizing the ambient dew point temperature. This can enhance the dehumidification capacity of the dehumidification system in different scenarios, so that it can effectively dehumidify in different scenarios.

[0129] S404. Determine the target deviation range corresponding to the first temperature deviation; where different deviation ranges correspond to different fan operating states.

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

[0131] The target deviation range can refer to the range in which the value of the first temperature deviation falls, and the target deviation range can be a pre-set range.

[0132] For example, the target operating state of the fan can be determined based on the different operating states of the fan corresponding to different preset deviation ranges. The control device can determine the target operating state of the fan by identifying the target deviation range in which the first temperature deviation lies, and thus determining that the target operating state of the fan is the operating state of the fan corresponding to that target deviation range.

[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 operate at its maximum speed; when the difference is between 10°C and 15°C, the fan can operate at a medium speed; and when the difference is greater than 15°C, the fan can operate at a low speed. The maximum, medium, and low speeds can all be preset speeds, and these three can be relative speeds.

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

[0135] In some specific embodiments, Figure 5 Flowchart of the dehumidification control method provided in this application Figure 2 ,like Dehumidification mode selection determination combination As shown, in this embodiment... Dry-bulb temperature - dew-point temperature < 10°C Based on the embodiments, the dehumidification control method is described by way of example. The method may specifically include: S501 to S509, wherein:

[0136] S501, Obtain the current value of the temperature and humidity sensor 118; wherein, when the dehumidification system is powered on, the ambient humidity and the dry bulb temperature that can characterize the ambient temperature are obtained.

[0137] S502. Calculate the current ambient dew point temperature; wherein, the ambient dew point temperature is calculated by obtaining the ambient humidity and dry bulb temperature.

[0138] S503, the ambient humidity is greater than the humidity when the machine is turned on; in dehumidification off mode, the dehumidification mode can be turned on if the above conditions are met.

[0139] S504. The ambient dew point temperature is greater than the start-up dew point temperature. In dehumidification off mode, the dehumidification mode can be turned on if the above conditions are met.

[0141] S506. Calculate the first deviation and the second deviation; wherein, calculate the first deviation between the dry bulb temperature and the ambient dew point temperature, and calculate the second deviation between the ambient dew point temperature and the start-up dew point temperature;

[0142] S507, Dehumidifier Mode Selection; After the dehumidifier is turned on, the dehumidification mode is automatically selected; for example, the dehumidification modes include:

[0143] Mode 1: When the difference between the dry bulb temperature and the dew point temperature of the environment to be dehumidified is <10℃ and the dew point temperature is > the start-up dew point temperature, the compressor runs at 100% full speed and the circulating fan runs at 100% speed.

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

[0145] Mode 3: 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 greater than the start-up dew point temperature, the compressor runs at 100% full speed and the circulating fan runs at 60% speed.

[0146] Mode 4: When the difference between the dry bulb temperature of the dehumidified environment and the ambient dew point temperature is <10℃, and the dew point temperature is < the start-up dew point temperature, the compressor runs at 70% full speed and the circulating fan runs at 80% speed.

[0147] Mode 5: When the difference between the dry bulb temperature of the dehumidified environment and the ambient dew point temperature is 10℃~15℃, and the dew point temperature is < the start-up dew point temperature, the compressor runs at 70% full speed and the circulating fan runs at 60% 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 start-up dew point temperature, the compressor runs at 70% full speed and the circulating fan runs at 40% speed.

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

[0150] The specific forms of dehumidification modes are shown in Table 1 and Table 2.

[0155] S508. Does the dehumidification shutdown condition meet?

[0156] S509, Exit dehumidification mode.

[0157] During dehumidification operation, the dehumidification shutdown conditions are constantly checked. These conditions include both logical and time-based checks. The logical dehumidification shutdown condition is as follows: when the ambient humidity is lower than the dehumidification shutdown set humidity (shutdown humidity) and the ambient dew point temperature is higher than the dehumidification shutdown set dew point temperature (shutdown dew point temperature), the dehumidification mode is shut down. The time-based dehumidification shutdown condition is as follows: when the dehumidification duration is detected to be longer than the set dehumidification shutdown time, the dehumidification mode is shut down. This time-based dehumidification shutdown condition is a supplement to the logical dehumidification shutdown condition and is designed to prevent the dehumidifier from dehumidifying ineffectively for extended periods in extreme conditions or when the temperature and humidity sensor 118 readings are incorrect.

[0158] In this embodiment, the above-described control method can solve the condensation problem on surfaces with constant dew point temperatures; it can achieve lower dehumidification surface temperatures, ensuring dehumidification capacity in environments with high dry-bulb temperatures and low relative humidity, and achieving dehumidification under conditions of large dry-bulb dew point temperature differences; it can achieve 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, and can reduce humidity fluctuations in the dehumidified environment. By combining rapid dehumidification with slow dehumidification, it avoids fluctuations in the relative humidity of the dehumidified environment caused by the start and stop of the dehumidifier.

[0159] In one exemplary embodiment, Figure 6 Flowchart of the dehumidification control method provided in this application Figure 2 ,like Figure 7 As shown, in this embodiment... Figure 6 Based on the embodiments, the steps of S201 are described by way of example. In step S201, the target operating state of the dehumidifier and the target operating state of the fan are determined according to the dry bulb temperature, the ambient dew point temperature and the preset start-up dew point temperature. Specifically, this may include steps S601 to S604, wherein:

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

[0161] S602. When the dehumidifier and fan are running, determine the first temperature deviation between the dry bulb temperature and the ambient dew point temperature, and the second temperature deviation between the ambient dew point temperature and the start-up dew point temperature.

[0162] S603. Based on the first temperature deviation, determine the target operating state of the fan.

[0163] S604. Based on the second temperature deviation, determine the target operating state of the dehumidifier.

[0164] The initial running state can refer to the state when the program is started, and the initial running state can be a preset start state.

[0165] For example, when the ambient humidity and / or ambient dew point temperature meet the dehumidification conditions, the control device can control the dehumidification device and the fan to operate in a corresponding preset initial operating state. After the device is turned on, a first temperature deviation between the dry-bulb temperature and the ambient dew point temperature can be determined, and based on this first temperature deviation, a target operating state for the fan can be determined, and the fan can be controlled to operate in the target state. The control device can also determine a second temperature deviation between the ambient dew point temperature and the start-up dew point temperature, and based on this second temperature deviation, a target operating state for the dehumidification device can be determined.

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

[0167] In this embodiment, by means 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, thereby enabling the dehumidification system to enhance the dehumidification effect in different environmental scenarios.

[0168] Optionally, in step S201, determining the target operating state of the dehumidifier based on the dry-bulb temperature, ambient dew point temperature, and preset start-up dew point temperature may further include:

[0169] Control the dehumidifier to operate in the preset initial operating state, and control the fan to operate in the preset initial operating state.

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

[0171] The target operating state of the dehumidifier is determined based on the humidity deviation.

[0172] The start-up humidity setting refers to the humidity level set when the dehumidification system is turned on. Humidity deviation refers to the difference between the ambient humidity and the start-up humidity. Humidity deviation can be either signed or unsigned data.

[0173] For example, when 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 the corresponding preset initial operating state. After the 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 start-up humidity, so as to better control the operating state of the dehumidification device, thereby better controlling the dehumidification device and thus better dehumidifying the current environment, thereby achieving better dehumidification effect for different environmental scenarios.

[0174] In some specific embodiments, Figure 7 Flowchart of the dehumidification control method provided in this application Figure 2 ,like Figure 1 As shown, in this embodiment... Figure 1 Based on the embodiments, the dehumidification control method is described by way of example. The method may specifically include: S701 to S713, wherein:

[0175] S701, Obtain the current value of temperature and humidity sensor 118.

[0176] S702. Calculate the current ambient dew point temperature.

[0177] S703, relative humidity is higher than the dehumidification start setting humidity.

[0178] S704, the dew point temperature is greater than the dew point set when dehumidification is turned on.

[0179] S705, turn on dehumidification mode.

[0180] The steps S701 to S705 can be referred to the steps S501 to S505 above.

[0181] S706, Dehumidifier operates at 60% speed. Specifically, after dehumidification is activated, the dehumidifier operates at 60% speed.

[0182] S707, Dehumidifier PID Control Deviation Detection. Specifically, the dehumidifier performs PID control deviation detection and issues a speed command for the dehumidifier in the next cycle.

[0183] S708, Dehumidifier Frequency Increase. The dehumidifier uses PID positive control to adjust its speed based on a second temperature deviation between the ambient dew point temperature and the start-up dew point temperature. When the second temperature deviation indicates that the ambient dew point temperature is higher than the start-up dew point temperature, or the ambient humidity is higher than the start-up humidity, the dehumidifier will increase its frequency, with a speed adjustment range of 50%~100%. The default dew point temperature of the dehumidifier is 18℃. The dehumidifier speed control PID is a position incremental PID. For example, if the current fan speed is 80% and the current actual ambient dew point temperature is 19℃, the dehumidifier speed in the next cycle will be 80% + increment.

[0184] S709, Circulating fan speed is 100%. Specifically, after dehumidification is turned on, the circulating fan runs at 100% speed.

[0185] S710, Fan PID Control Deviation Detection. Specifically, the circulating fan performs PID control deviation detection and issues a speed command for the circulating fan in the next cycle.

[0186] S711, Fan Speed ​​Reduction. The circulating fan uses PID negative control to adjust its speed based on the first temperature deviation between the actual dry-bulb temperature and the ambient dew point temperature. When the first temperature deviation exceeds a preset temperature difference threshold, the dehumidifying circulating fan will reduce its speed by 50% to 100%. The default temperature difference threshold is set to 10℃. The fan speed control PID is a position incremental PID. For example, if the current fan speed is 70% and the current first temperature deviation is 9℃, the fan speed in the next cycle will be 70% + increment.

[0187] S712, Does the dehumidification shutdown condition meet?

[0188] S713, Exit dehumidification mode.

[0189] The steps in S712 to S713 are the same as those in S508 to S509 described above.

[0190] In this embodiment, the above-described control method can solve the condensation problem on surfaces with constant dew point temperatures; it can achieve lower dehumidification surface temperatures, ensuring dehumidification capacity in environments with high dry-bulb temperatures and low relative humidity, and achieving dehumidification under conditions of large dry-bulb dew point temperature differences; it can achieve 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, and can reduce humidity fluctuations in the dehumidified environment. By combining rapid dehumidification with slow dehumidification, it avoids fluctuations in the relative humidity of the dehumidified environment caused by the start and stop of the dehumidifier.

[0191] In one exemplary embodiment, the dehumidification system further includes a heating device; the method further includes:

[0192] When the dehumidifier is running, obtain the current ambient evaporation temperature and / or drain pipe temperature;

[0193] If the evaporation temperature and / or the drain pipe temperature are lower than the preset heating temperature, the dehumidification device will be shut down and the heating device will be turned on.

[0194] Among them, the heating device can refer to... Figure 1 The drain pipe uses a heating wire 115 or a heater. The evaporation temperature can be controlled by... Figure 8 The temperature can be detected by the evaporation temperature sensor 119, and the drain pipe temperature can be obtained through... Figure 8 The temperature is detected by the drain pipe temperature sensor 116. The temperature to be heated refers to the temperature at which heating is required. If it is lower than the temperature to be heated, it means that the temperature is too low and heating is needed.

[0195] Optionally, Figure 2 A flowchart illustrating the heating defrosting steps provided in this application is shown below. Figure 9 As shown, in this embodiment... Figure 9 Based on the embodiments, the dehumidification control method is described by way of example. The method may further include a defrosting step, specifically including: S801 to S806, wherein:

[0196] S801, Dehumidification Status Detection; wherein, the control device can perform dehumidification status detection at any time when the dehumidifier is powered on.

[0197] S802, Is dehumidification on? If the control device detects that dehumidification is on, proceed to the next step.

[0198] S803, Is the evaporation temperature sensor 119 < -2℃? The control device obtains the value of the evaporation temperature sensor 119 and determines whether the current value of the evaporation temperature sensor 119 is less than the defrost start setting temperature. If so, the next step is executed.

[0199] S804. Exit dehumidification and start heating; wherein, the control device can exit the dehumidification mode and start the heater.

[0200] S805. Does the heating shutdown condition meet? Wherein, when the heating is on, it is determined whether the heating shutdown condition is met. If the heating shutdown condition is met, a heating shutdown command is issued. The heating shutdown condition includes the evaporation temperature sensor value being greater than the defrost start setting temperature plus 15°C hysteresis or a heater circuit fault alarm.

[0201] S806. Turn off heating. The control device can control the exit from heating mode.

[0202] Optionally, Figure 2 The flowchart illustrating the de-icing process of the drainage pipe provided in this application is as follows: Figure 10As shown, in this embodiment... Figure 10 Based on the embodiments, the dehumidification control method is described by way of example. The method may also include a step of de-icing the drain pipe, specifically including: S901 to S906, wherein:

[0203] S901, Dehumidification Status Detection; wherein, the control device can perform dehumidification status detection at any time when the dehumidifier is powered on.

[0204] S902, Is dehumidification on? If the control device detects that dehumidification is on, proceed to the next step.

[0205] S903, whether the drain pipe temperature sensor 116 is < -2℃; wherein, the control device obtains the value of the evaporation temperature sensor 119, determines whether the current value of the evaporation temperature sensor 119 is < the defrost start setting temperature, if so, then continue to the next step.

[0206] S904. Exit dehumidification and turn on heating; wherein, the control device can exit the dehumidification mode and turn on the heating element.

[0207] S905. Does the heating shutdown condition meet? Wherein, when the heating is on, it is determined whether the heating shutdown condition is met. If the heating shutdown condition is met, a heating shutdown command is issued. The heating shutdown condition includes the evaporation temperature sensor 119 value being greater than the defrost start setting temperature plus 15°C hysteresis or a heater circuit fault alarm.

[0208] S906. Turn off heating. The control device can control the exit from heating mode.

[0209] In this embodiment, by obtaining the current ambient evaporation temperature and / or drain pipe temperature during the operation of the dehumidifier, and controlling heating based on the fact that the evaporation temperature and / or drain pipe temperature are lower than the preset heating temperature and the required heating temperature, the effects of frost and / or ice on dehumidification can be avoided. For example, the drain pipe can be prevented from freezing and affecting condensation drainage, thereby ensuring enhanced dehumidification effect and ensuring the correctness of dehumidification.
