[0002] With the wide application of humidification technology, people's demand for humidification is also increasing. For example, when the room is relatively dry, the air in the room needs to be humidified to make the human body more comfortable. For example, the low air humidity in the machine room can cause damage to the electronic components of the electronic equipment, so the air in the machine room needs to be humidified in time.

[0003] In the related art, the air is mainly humidified by a wet membrane humidifier. The wet membrane humidifier includes a fan and a wet membrane core. The fan generates dry air at a fixed rotating speed.

[0050] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0051] It should be understood that the "multiple" mentioned in the present application refers to two or more than two. In the description of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B; "and / or" in the present application is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent three cases of A alone, A and B together, and B alone. In addition, in order to clearly describe the technical solutions of the present application, the same items or similar items with basically the same functions and roles are distinguished by using "first", "second", etc. The skilled in the art can understand that "first", "second", etc. do not limit the quantity and execution order, and "first", "second", etc. also do not necessarily mean different.

[0052] The phrase "one embodiment" or "some embodiments" appearing in the present application means that the specific features, structures or characteristics described in the embodiment are included in one or more embodiments of the present application. Therefore, the phrases "in one embodiment", "in some embodiments", "in other some embodiments", "in further some embodiments" appearing in the present application do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized. In addition, the terms "include", "contain", "have" and their variants mean "include but not limited to", unless otherwise specifically emphasized.

[0053] Before the embodiments of the present application are explained in detail, the application scenarios of the embodiments of the present application are described.

[0054] With the wide application of humidification technology, people's demand for humidification is also increasing. For example, when the room is relatively dry, the air in the room needs to be humidified to make the human body more comfortable. For example, the air humidity in the computer room is low, which will cause the electronic components of the electronic equipment to be damaged, so the air in the computer room needs to be humidified in time when the air humidity in the computer room is low.

[0055] In the related art, the humidification device generally uses the cold evaporation method for humidification. The humidification device includes a fan and a wet membrane core body. The water content of the wet membrane core body is controlled, and the fan generates dry air at a fixed speed to pass through the wet membrane core body, so that the water in the wet membrane core body is evaporated and brought into the air, achieving the effect of humidifying the air. However, in this humidification method, the fan humidifies the air at a fixed speed, so it cannot control the humidification amount of the air, the humidification flexibility is poor, and the humidification effect is affected.

[0056] Therefore, the embodiment of the present application provides a fan speed adjustment method. The target evaporation efficiency of the wet membrane core body is determined according to the current air humidity of the environment and the preset air humidity to be reached, and then the speed of the fan is adjusted according to the target evaporation efficiency, so that the wet membrane core body humidifies the air at the target evaporation efficiency. In this way, the speed of the fan is adjusted flexibly according to the humidification demand of the environment to humidify the air, thereby improving the humidification flexibility and ensuring the humidification effect.

[0057] The humidification process of the humidification device related to the embodiment of the present application is exemplarily described below. It can be understood that the structure and humidification process of the humidification device described below are only an example and do not limit the embodiment of the present application. In actual application, the structure and humidification process of the humidification device can also be realized by other components or methods, and the embodiment of the present application does not limit this.

[0058] An example of the humidification process of the humidification device is shown in the following table. Figure 1 is a structural schematic diagram of a humidification device provided by the embodiment of the present application. The humidification device is a device for humidifying air. Referring to Figure 1 , the humidification device can include a fan, a water tank, a water distributor, a wet membrane core body, etc.

[0059] The fan provides a wind source for evaporating water. The water tank provides a water source for humidification. The water distributor is used to uniformly distribute the water in the water tank to the wet membrane core body. The wet membrane core body is used to absorb water and form a uniform water film.

[0060] The humidifying device works, the water in the water tank is sprinkled on the top end of the wet membrane core body, the water penetrates downward along the surface of the wet membrane core body under the action of gravity, so that the wet membrane core body fully absorbs the moisture and forms a uniform water film. Then, the fan outputs dry air to evaporate the moisture of the wet membrane core body, when the dry air passes through the wet membrane core body, it will have a large area of contact with the moisture on the surface of the wet membrane core body, so that the moisture can fully absorb the heat in the air and vaporize into gas and be transported into the air, thereby achieving the purpose of humidifying the air.

[0061] The humidifying efficiency of the humidifying device depends on the evaporation efficiency of the wet membrane core body, the greater the evaporation efficiency of the wet membrane core body, the faster the air humidification speed, and the higher the humidifying efficiency. The evaporation efficiency of the wet membrane core body is affected by the speed of the fan, the higher the speed of the fan, the greater the air speed through the wet membrane core body, the greater the influence on the evaporation efficiency of the wet membrane core body. Therefore, the humidifying efficiency of the humidifying device will be affected by the speed of the fan.

[0062] Therefore, the fan speed adjustment method provided by the embodiments of the present application can determine the most suitable target evaporation efficiency of the wet membrane core body in the current environment according to the humidification demand of the current environment, and adjust the speed of the fan accordingly, so that the humidifying device can humidify according to the humidification demand of the current environment with flexible humidifying efficiency, and ensure the humidifying effect.

[0063] The fan speed adjustment method provided by the embodiments of the present application will be explained in detail below.

[0064] Figure 2 is a flow chart of a fan speed adjustment method provided by an embodiment of the present application. The method is applied to a humidifying device, and exemplarily, the humidifying device can be a wet membrane humidifier. Referring to Figure 2 , the method comprises the following steps:

[0065] Step 201: The humidifying device obtains a first humidity value, which is the air humidity value of the environment where the humidifying device is located.

[0066] Optionally, a humidity sensor can be arranged on the outer surface of the humidifying device, which can detect the air humidity value of the environment where it is located. For example, the humidity sensor can be a thermal energy humidity sensor. The humidifying device can detect the first humidity value through the humidity sensor, so that an accurate first humidity value can be obtained.

[0067] Step 202: The humidifying device determines a humidification demand value according to the first humidity value and a preset humidity value to be reached, which is used to indicate the degree of demand for air humidification.

[0068] Before the humidifying device starts to humidify, a preset humidity value can be set, which is a humidity value that needs to be reached. In this way, after the first humidity value is detected, the humidifying requirement value can be determined according to the difference between the first humidity value and the preset humidity value, and the humidifying requirement value can reflect whether the air needs to be humidified. The preset humidity value can be set in advance, for example, it can be set before the humidifying device is shipped, or it can be set by the user during the use of the humidifying device, and the embodiments of the present application do not limit this.

[0069] The humidifying requirement value is positively correlated with the degree of requirement for humidifying the air. The higher the humidifying requirement value, the higher the degree of requirement for humidifying the air; the lower the humidifying requirement value, the lower the degree of requirement for humidifying the air. It should be noted that when the humidifying requirement value is greater than 0, it means that there is a humidifying requirement. When the humidifying requirement value is less than or equal to 0, it means that there is no humidifying requirement, and the air does not need to be humidified.

[0070] Optionally, the operation of determining the humidifying requirement value according to the first humidity value and the preset humidity value that needs to be reached by the humidifying device can be: determining the humidifying requirement value according to the first humidity value and the preset humidity value by the formula CFHu=H s -H1-H β -H1-H α .

[0071] H β is the humidity fluctuation value. Since the air humidity of the environment cannot be avoided when measuring, in the embodiments of the present application, H β is used to eliminate the measurement error of the first humidity value caused by the fluctuation of the air humidity, so that the determined humidifying requirement value is more accurate. H β can be set in advance, for example, it can be set in advance by the technician according to experience.

[0072] H α is the humidity control interval value, which is the maximum difference between the air humidity value of the environment and the preset humidity value that can be reached under normal circumstances. H α can be set in advance, for example, it can be set in advance by the technician according to experience.

[0073] Since H α is the maximum difference between the air humidity value of the environment and the preset humidity value that can be reached under normal circumstances, and H s -H1-H β is the difference between the current air humidity value of the environment and the preset humidity value, so H s -H1-H β is divided by H αA humidification demand value reflecting a current degree of demand for air humidification can be obtained.

[0074] Step 203: If the humidification demand value is greater than 0, the humidification device determines a target evaporation efficiency according to the humidification demand value, the target evaporation efficiency being an evaporation efficiency required to be reached by the wet membrane core of the humidification device.

[0075] If the humidification demand value is greater than 0, it indicates that there is a demand for humidification, and the humidification device needs to humidify. To enable the humidification device to meet the current environmental demand for humidification, the most suitable evaporation efficiency (i.e., the target evaporation efficiency) of the wet membrane core in the current environment can be determined according to the humidification demand value.

[0076] Optionally, the operation of determining the target evaporation efficiency according to the humidification demand value can be: obtaining a first temperature value, a second temperature value, and a second humidity value, the first temperature value being a temperature of a windward surface of the wet membrane core, the second temperature value being a temperature of a leeward surface of the wet membrane core, and the second humidity value being a humidity of the windward surface of the wet membrane core; determining a maximum evaporation efficiency that can be reached by the wet membrane core in the current environment according to the first temperature value, the second temperature value, and the second humidity value; and determining the target evaporation efficiency according to the humidification demand value and the maximum evaporation efficiency.

[0077] The maximum evaporation efficiency represents the maximum evaporation efficiency that can be reached by the wet membrane core in the environment of the first temperature value, the second temperature value, and the second humidity value. In this case, the most suitable target evaporation efficiency of the wet membrane core in the current environment can be determined according to the humidification demand value of the current environment and by referring to the maximum evaporation efficiency.

[0078] Optionally, a temperature sensor and a humidity sensor can be arranged on the windward surface of the wet membrane core, and a temperature sensor can be arranged on the leeward surface of the wet membrane core. For example, the temperature sensor can be an infrared temperature sensor, and the humidity sensor can be a thermal energy humidity sensor. In this way, the humidification device can detect the second humidity value through the humidity sensor on the windward surface of the wet membrane core, detect the first temperature value through the temperature sensor on the windward surface of the wet membrane core, and detect the second temperature value through the temperature sensor on the leeward surface of the wet membrane core, so as to obtain accurate first temperature value, second temperature value, and second humidity value.

[0079] The first temperature value, the second temperature value, and the second humidity value can reflect the surrounding environment state of the wet membrane core, which will affect the evaporation efficiency of the wet membrane core, and thus the maximum evaporation efficiency that can be reached by the wet membrane core in the current environment can be determined through the first temperature value, the second temperature value, and the second humidity value.

[0080] Optionally, the operation of determining the maximum evaporation efficiency of the wet membrane core in the current environment according to the first temperature value, the second temperature value and the second humidity value can be: dividing the difference between the first temperature value and the second temperature value by the difference between the first temperature value and the second humidity value to obtain the maximum evaporation efficiency.

[0081] The process of determining the maximum evaporation efficiency can be represented by the formula , wherein η represents the maximum evaporation efficiency, t1 is the first temperature value, t2 is the second temperature value, and t s is the second humidity value.

[0082] Optionally, the operation of determining the target evaporation efficiency according to the humidification demand value and the maximum evaporation efficiency can be: if the humidification demand value is greater than or equal to the humidification demand threshold, determining the maximum evaporation efficiency as the target evaporation efficiency; if the humidification demand value is greater than 0 and less than the humidification demand threshold, determining the target evaporation efficiency according to the minimum evaporation efficiency required by the wet membrane core, the maximum evaporation efficiency and the humidification demand value.

[0083] If the humidification demand value is greater than or equal to the humidification demand threshold, it means that the current demand for air humidification is high, so the maximum evaporation efficiency can be determined as the target evaporation efficiency, so that the wet membrane core humidifies at the maximum evaporation efficiency, thereby quickly increasing the air humidity and quickly meeting the humidification demand.

[0084] If the humidification demand value is greater than 0 and less than the humidification demand threshold, it means that the current demand for air humidification is low. In this case, if the wet membrane core still humidifies at the maximum evaporation efficiency, it may result in over-humidification, so the target evaporation efficiency can be determined according to the minimum evaporation efficiency required by the wet membrane core, the maximum evaporation efficiency and the humidification demand value, to improve the control accuracy of humidification and avoid over-humidification, thereby ensuring the stability of humidification.

[0085] Optionally, the humidification demand threshold can be set in advance, for example, it can be set in advance according to the environment that needs to be humidified. For example, the humidification demand threshold of an A-level machine room can be set to 65%, the humidification demand threshold of a B-level machine room can be set to 70%, and the humidification demand threshold of a C-level machine room can be set to 80%. A, B and C are used to represent the importance level of the machine room, A is the highest level, and C is the lowest level.

[0086] The minimum evaporation efficiency represents the minimum evaporation efficiency required by the wet membrane core when the humidification device is working, and the minimum evaporation efficiency can be set in advance.

[0087] Optionally, the operation of determining the target evaporation efficiency of the wet membrane core according to the minimum evaporation efficiency required to be reached by the wet membrane core, the maximum evaporation efficiency and the humidification demand value can be: determining the target evaporation efficiency according to the minimum evaporation efficiency, the maximum evaporation efficiency and the humidification demand value by the formula η z =(η-η s )×CFHu+η s , wherein η z is the target evaporation efficiency, η s is the maximum evaporation efficiency, η e is the minimum evaporation efficiency, and CFHu is the humidification demand value.

[0088] η-η e indicates how much the wet membrane core needs to increase from the minimum evaporation efficiency to reach the maximum evaporation efficiency, and thus (η-η s )×CFHu is the evaporation efficiency required to be increased by the wet membrane core at the demand degree indicated by the humidification demand value, and then (η-η s )×CFHu is added to η s to obtain the target evaporation efficiency required to be reached by the wet membrane core at the demand degree indicated by the humidification demand value.

[0089] As the air humidity continuously increases, the demand degree of air humidification continuously decreases. To avoid over-humidification, the target evaporation efficiency can be determined according to the minimum evaporation efficiency, the maximum evaporation efficiency and the humidification demand value in a linear interpolation manner shown in the above formula. In this way, as the humidification demand value continuously decreases, the determined target evaporation efficiency also continuously decreases, thereby realizing fine control of the evaporation efficiency of the wet membrane core by the humidification device, and further improving the control accuracy of humidification and ensuring the stability of humidification.

[0090] The embodiments of the present application can quickly humidify when the humidification demand is large, and can fine humidify when the humidification demand is small, thereby flexibly meeting the current environmental humidification demand and improving the humidification effect.

[0091] Further, after the humidification device determines the humidification demand value in step 202, if the humidification demand value is less than or equal to 0, the rotation speed of the fan is controlled to 0 to stop humidification.

[0092] If the humidification demand value is less than or equal to 0, it indicates that there is no current humidification demand, and thus the rotation speed of the fan can be adjusted to 0 to stop humidification.

[0093] Step 204: The humidification device adjusts the rotation speed of the fan of the humidification device according to the target evaporation efficiency.

[0094] The target evaporation efficiency is the most suitable evaporation efficiency of the wet membrane core in the current environment determined by the humidifying device, so that the rotation speed of the fan of the humidifying device can be adjusted according to the target evaporation efficiency, so that the evaporation efficiency of the wet membrane core is the target evaporation efficiency.

[0095] Optionally, the operation of adjusting the rotation speed of the fan of the humidifying device according to the target evaporation efficiency can be: determining a target wind speed according to the target evaporation efficiency by the following formula; and adjusting the rotation speed of the fan according to the target wind speed.

[0096]

[0097] v is the target wind speed. K1 and K2 are constants, which can be set in advance. t1 is the first temperature value, t2 is the second temperature value, t s is the second humidity value, and η z is the target evaporation efficiency. A is a constant, which can be set in advance. d is the inlet humidity content of the wet membrane core.

[0098] Optionally, the formula for determining the target wind speed according to the target evaporation efficiency can be obtained by the technician through experimental testing. For example, the technician can obtain a plurality of sets of evaporation efficiency and wind speed through experimental testing, and then fit the plurality of sets of evaporation efficiency and wind speed to obtain the formula.

[0099] The target wind speed is the wind speed that can make the evaporation efficiency of the wet membrane core reach the target evaporation efficiency. Adjusting the rotation speed of the fan according to the target wind speed can make the wind speed of the wind generated by the fan be the target wind speed, so that the evaporation efficiency of the wet membrane core can be the target evaporation efficiency.

[0100] Optionally, the operation of adjusting the rotation speed of the fan of the humidifying device according to the target wind speed can be: determining a target rotation speed according to the target wind speed by the formula r=K3υ 2 +K4υ+K5, and adjusting the rotation speed of the fan to the target rotation speed. Wherein, r is the target rotation speed, υ is the target wind speed, K3, K4 and K5 are constants, which can be set in advance. The target rotation speed is the rotation speed that can make the wind generated by the fan be the target wind speed.

[0101] Optionally, the formula for determining the target rotation speed according to the target wind speed can be obtained by the technician through experimental testing. For example, the technician can obtain a plurality of sets of wind speed and fan rotation speed through experimental testing, and then fit the plurality of sets of wind speed and fan rotation speed to obtain the formula.

[0102] It should be noted that steps 201 to 204 can be continuously performed by the humidification device during the humidification process, for example, the humidification device can execute steps 201 to 204 periodically (e.g., every 1 second, every 2 seconds, etc.). In this way, the humidification requirement value can be determined according to the current air humidity value and the preset humidity value throughout the humidification process, and the speed of the fan can be adjusted accordingly, so that the humidification device can accurately and stably humidify.

[0103] For ease of understanding, the above fan speed adjustment method is exemplified as follows.

[0104] As an example, an enterprise usually sets up electronic devices such as servers in a machine room to maintain the operation of daily business, but these electronic devices will continuously generate heat during operation, causing the air humidity to continuously decrease. When the air humidity decreases to a certain extent, static electricity will appear between the electronic components of the electronic devices, causing damage to the electronic devices. To avoid this situation, a humidification device is usually installed to humidify the air in the machine room.

[0105] Before the humidification device starts to work, the preset humidity value and the humidification requirement threshold value are set. Then, the humidification device is started to humidify the machine room, and the humidification device starts to periodically detect the air humidity of the environment, i.e., the first humidity value.

[0106] Since the air humidity of the environment is small at the beginning, the difference between the detected first humidity value and the preset humidity value is relatively large, so the humidification requirement value is greater than or equal to the humidification requirement threshold value. In this case, the target evaporation efficiency determined by the humidification device is the maximum evaporation efficiency that the wet membrane core can achieve in the current environment, and the speed of the fan is adjusted accordingly so that the wet membrane core can humidify the air at the maximum evaporation efficiency. In this way, the air can be quickly humidified in the initial period of humidification of the humidification device, so that the air humidity can be quickly increased.

[0107] As the humidification proceeds, the air humidity of the environment gradually increases, and the difference between the detected first humidity value and the preset humidity value gradually decreases, so the humidification requirement value gradually decreases until the humidification requirement value is greater than 0 and less than the humidification requirement threshold value. In this case, the humidification device can determine the target evaporation efficiency between the maximum evaporation efficiency and the minimum evaporation efficiency that the wet membrane core can achieve in the current environment according to the humidification requirement value in a linear interpolation manner, and adjust the speed of the fan accordingly so that the wet membrane core can humidify the air at the target evaporation efficiency. In this way, after the humidification device has been humidified for a period of time, the humidification device can finely humidify according to the current environmental humidification requirement, avoiding over-humidification. In this way, the control accuracy of humidification is improved, and the stability of humidification is ensured.

[0108] With the continuous humidification, the air humidity of the environment continues to increase until the detected first humidity value is the preset humidity value, at which time the humidification demand value is less than or equal to 0. In this case, the humidification device can control the speed of the fan to be 0 to stop humidification, so that the air humidity value of the current environment is maintained at the preset humidity value. In this way, through flexible adjustment of the speed of the fan during the entire humidification process of the humidification device, better humidification effect can be ensured.

[0109] In the embodiments of the present application, the air humidity value of the environment where the humidification device is located, i.e., the first humidity value, is obtained. Then, the humidification demand value is determined according to the first humidity value and the preset humidity value to be reached. If the humidification demand value is greater than 0, the target evaporation efficiency is determined according to the humidification demand value, and finally the speed of the fan of the humidification device is adjusted according to the target evaporation efficiency, so that the wet membrane core body humidifies the air at the target evaporation efficiency. In this way, the speed of the fan is flexibly adjusted according to the humidification demand of the environment to perform humidification, thereby improving the humidification flexibility and ensuring the humidification effect.
