[0002] With the improvement of people's living standards, air conditioning equipment has been gradually widely used in various occasions. When the air conditioner cools, if the ambient humidity is large, the hot and humid air near the air outlet deflector will condense and produce condensation, mainly manifested in panel dripping, wall dampness and air outlet dripping phenomenon; and the greater the air humidity and temperature difference, the more serious the condensation.

[0003] The existing anti-condensation control measures trigger the cut-off of the radiation surface cold source when the temperature condition reaches the condensation condition. In this way, even if the cold source is cut off, due to the response of the system and the increase of the indoor radiation surface temperature, it takes a certain time and cannot effectively reduce the condensation risk, and the condensation phenomenon is still more likely to occur.

[0043] The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts are within the scope of the present application.

[0044] In the description of the present application, it needs to be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified.

[0045] In this application, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any implementation described as "exemplary" in this application is not necessarily to be construed as preferred or advantageous over other implementations. The following description is presented to enable any person skilled in the art to make and use the application. In the following description, for purposes of explanation, specific details are set forth. It will be apparent to those skilled in the art that the present application can be practiced without the specific details presented. In other instances, well-known structures and processes are not shown in detail in order to avoid obscuring the present application. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features presented herein.

[0046] The embodiments of the present application provide an air conditioner anti-condensation control method and device, a storage medium and an air conditioner, which are described in detail as follows.

[0047] There is a type of air conditioner without a humidity sensor installed to obtain air humidity in real time, so this type of air conditioner cannot perform anti-condensation control according to real-time humidity of the environment. The present application mainly aims at this type of air conditioner that cannot obtain air humidity in real time.

[0048] The relative humidity refers to the percentage of water vapor pressure in the air to the saturated water vapor pressure at the same temperature, and the greater the value, the higher the humidity, that is, the air humidity value in the present application. In the embodiments of the present application, the humidity value is expressed in percentage.

[0049] In the embodiments of the present application, the air humidity prediction value provided by the weather forecast can be obtained, and the air humidity prediction value is taken as the actual air humidity value to perform anti-condensation control. For example, the air humidity prediction value provided by the weather forecast can be taken as the actual air humidity value to perform anti-condensation control. Figure 1The diagram shown is a schematic representation of an embodiment of humidity variation over time provided in this application. Figure 1 As can be clearly seen, air humidity changes constantly over time, with different humidity values ​​at different times. Furthermore, in actual weather forecasts, the humidity prediction value provided is usually the humidity value at a specific moment, rather than the humidity value for a specific time period. For example... Figure 1 The value in the middle represents the predicted air humidity for each hour.

[0050] It should be noted that, in the embodiments of this application, the obtained predicted air humidity value can be the air humidity value corresponding to different times within a period of time, and the duration of any two adjacent times is the same. Figure 1 For example, the predicted air humidity value corresponds to each hour. Different times correspond to a different humidity prediction value, and there is an hour interval between any two adjacent times.

[0051] Meanwhile, in the embodiments of this application, the air humidity forecast value provided by the weather forecast can be directly... Figure 1 The data is presented in chart form; alternatively, you can directly obtain the predicted air humidity value for each moment.

[0052] like Figure 2 The diagram shown is a flowchart of an embodiment of the air conditioning anti-condensation control method in this application. The air conditioning anti-condensation control method includes:

[0053] 21. Obtain a set of predicted air humidity values ​​for anti-condensation control during the target time period.

[0054] In this embodiment of the application, the set of predicted air humidity values ​​obtained is the predicted air humidity values ​​at multiple different times within a certain period of time. Therefore, the set of predicted air humidity values ​​actually includes multiple predicted air humidity values, and multiple predicted air humidity values ​​correspond to multiple times, with the same duration between any two adjacent times.

[0055] Meanwhile, in the embodiments of this application, any two adjacent moments include a certain time period, and the air conditioner may turn on to cool at any time; regardless of when the air conditioner turns on to cool, the moment when the air conditioner turns on to cool corresponds to a time period, namely the target time period in the embodiments of this application.

[0056] In the embodiments of the present application, the local weather forecast can be directly obtained by the Internet of Things module which can be connected to the network, so as to obtain the air humidity prediction value set within the preset time period. In the actual weather forecast, the air humidity is usually time-periodic, that is, the air humidity at different time points is different. Therefore, the air humidity prediction value set obtained by the Internet of Things module includes a plurality of different air humidity prediction values, and different air humidity prediction values correspond to different time points.

[0057] In the embodiments of the present application, the air humidity prediction value can be obtained by using other methods or devices, which are not limited here.

[0058] In a specific embodiment of the present application, the air humidity prediction value set within 24 hours in the future of a certain region can be obtained, and 24 hours is divided into 12 time points with 2 hours as the time difference, and each time point corresponds to an air humidity prediction value. A total of 12 air humidity prediction values form the air humidity prediction value set within 24 hours. The preset time period can be 24 hours from 9:00 am of the current day to 9:00 am of the next day.

[0059] In some other embodiments of the present application, historical humidity data within a preset time period can also be obtained as air humidity prediction values. Specifically, historical humidity data of the same period within the past five years can be obtained, and the average value or the median value of the historical data corresponding to different time points is determined as the air humidity prediction value.

[0060] In the above embodiments, historical humidity data within a longer time period can also be obtained as air humidity prediction values. The more historical humidity data obtained, the more accurate the air humidity prediction values.

[0061] It should be noted that in the embodiments of the present application, if the air humidity prediction value set is obtained by using the weather forecast, the air humidity prediction value set obtained in different time periods can be different. In the actual air conditioner operation process, the air humidity prediction value set can be updated at a fixed frequency to obtain more accurate air humidity prediction values.

[0062] 22, detecting the working state of the air conditioner at the current time point.

[0063] In the embodiments of the present application, the working state of the air conditioner usually includes shutdown and non-working, or startup and cooling. In the embodiments of the present application, detecting the working state of the air conditioner at the current time point can include: detecting whether the air conditioner is powered on for the first time to cool at the current time point; or powered on after continuous shutdown for a first time period; or has been continuously running for a second time period.

[0064] The first time length can be the air balance time length of indoor and outdoor air after the air conditioner is turned off, that is, the time length required for the indoor and outdoor air humidity to reach balance after the air conditioner is turned off, and can usually be 0.5-1 hour, that is, the indoor and outdoor air humidity will reach a balance state within 0.5-1 hours after the air conditioner is turned off.

[0065] The second time length can be the air humidity update period in an open scene where indoor and outdoor air is frequently exchanged, such as a household living room or a shopping mall, a public place, and the like, that is, the air humidity update period under normal circumstances, and can usually be 1-2 hours, that is, as time elapses, the air humidity is updated once every 1-2 hours as the actual weather condition changes.

[0066] It should be noted that in the embodiments of the present application, the air humidity is updated as the actual weather state changes, and therefore the air humidity prediction value provided by the weather forecast is also variable. In actual situations, the air humidity is updated once every 1-2 hours, and therefore the air humidity prediction value provided by the weather forecast can also be updated once every 1-2 hours accordingly. That is, in the embodiments of the present application, the air humidity prediction value set can also be updated as time changes, and in the embodiments of the present application, the update period of the air humidity prediction value set can be the same as the air humidity update period of the open scene of the second time length. Specifically, both can be 1-2 hours.

[0067] 23. Controlling the air conditioner for anti-condensation according to the working state of the air conditioner and the air humidity prediction value set in the target time period.

[0068] In the embodiments of the present application, for this type of air conditioner that cannot obtain the air humidity in real time, the air humidity prediction value set is used to determine the environmental humidity value. Since the air has an impact on the current environmental humidity value when cooling or heating, the working state of the air conditioner also needs to be combined to control the air conditioner for anti-condensation.

[0069] The air conditioner anti-condensation control method provided in the embodiments of the present application judges the working state of the air conditioner and obtains an air humidity prediction value set for anti-condensation control in a target time period, and judges whether the air conditioner needs to be controlled for anti-condensation according to the working state of the air conditioner and the air humidity prediction value. In the case where the environmental humidity cannot be obtained in real time, the prediction value of the air humidity is used as the actual air humidity value, so that the control of the air conditioner for anti-condensation is more accurate, and the problem of anti-condensation error or non-entry in the case of hot and humid or dry weather is avoided.

[0070] In the above embodiments, different ambient humidity can cause the air conditioner to change its working state to adjust the ambient humidity to create a more comfortable environment; but this can also cause the air conditioner to produce condensation, affecting the operation of the air conditioner. Therefore, the air conditioner needs to be controlled to prevent condensation to avoid the problem of condensation prevention or not in humid and hot or dry weather conditions.

[0071] And according to the working state of the air conditioner and the set of air humidity prediction values, the air conditioner is controlled to prevent condensation in the target time period, which can include: determining the target ambient humidity value at the current time according to the working state of the air conditioner and the set of air humidity prediction values; and controlling the air conditioner to prevent condensation in the target time period according to the target ambient humidity value.

[0072] That is, the target ambient temperature value at the current time can be determined according to the working state of the air conditioner and the set of air humidity prediction values; and whether the air conditioner needs to prevent condensation in the next time period is determined according to the target ambient temperature value.

[0073] As shown in Figure 3 An embodiment process diagram for determining the target ambient humidity value provided by the embodiments of the present application can include:

[0074] 31、If the air conditioner is powered on for the first time to cool at the current time, or is powered on after being turned off for the first time length, or has been continuously running for the second time length, the last time adjacent to the current time is determined.

[0075] 32、In the set of air humidity prediction values, the air humidity prediction value corresponding to the last time is determined as the target ambient humidity value.

[0076] Specifically, if the air conditioner is powered on for the first time to cool at the current time, or is powered on after being turned off for the first time length, or has been continuously running for the second time length, it means that the air humidity has reached a balanced state and the air humidity will not fluctuate greatly.

[0077] At this time, the last time adjacent to the current time can be determined, and in the obtained set of air humidity prediction values, the air humidity prediction value corresponding to the last time is determined as the target ambient humidity value corresponding to the current time.

[0078] 33、If the air conditioner is not powered on for the first time to cool at the current time, or is powered on after being turned off for the first time length, or has been continuously running for the second time length, the humidity value of the air conditioner at the current time is kept unchanged.

[0079] Specifically, in the embodiments of the present application, the air conditioner will correspond to an air humidity value at any time. If the air conditioner is not powered on for the first time to refrigerate, but the continuous shutdown time of the air conditioner does not reach the first time length, or the continuous refrigeration time does not reach the second time length, it indicates that the change of the air humidity value of the air conditioner at this time has not been reflected in the weather forecast. At this time, the humidity value corresponding to the air conditioner remains unchanged.

[0080] In a specific embodiment of the present application, the air conditioner is powered on for the first time to refrigerate at 9:30. At this time, the air conditioner satisfies the first power-on refrigeration, and the air humidity value corresponding to the refrigeration at this moment needs to be updated to the air humidity prediction value corresponding to the last time in the air humidity prediction value set. Figure 1 Taking the air humidity prediction value set shown in the figure as an example, in the air humidity prediction value set obtained at 9:00, different air humidity prediction value sets are air humidity prediction values corresponding to integral point times, and the time length between any two adjacent times is one hour.

[0081] When the air conditioner is powered on for the first time to refrigerate at 9:30, the target environment humidity value at this time is the air humidity prediction value corresponding to 9:00. Taking the second time length as two hours and the humidity update period of the open scene as two hours as an example, as time changes, at 11:00, the humidity of the open scene has been updated, and a new air humidity prediction value set will be obtained. At 11:00, the air conditioner has been continuously refrigerating for one and a half hours, but has not reached the requirement of two hours of continuous refrigeration. At this time, the air humidity value remains unchanged, that is, the air humidity value at 9:00 is maintained as the target environment humidity value at 11:00.

[0082] In another specific embodiment of the present application, if the air conditioner is powered on for the first time to refrigerate at 9:30, the target environment humidity value at this time is the air humidity prediction value corresponding to 9:00. As time changes, at 10:00, the air conditioner has been continuously refrigerating for half an hour, and has not reached the requirement of two hours of continuous refrigeration. Therefore, the air humidity value at 10:00 is the air humidity value at 9:00. When the air conditioner is shut down at 10:00 and restarted to refrigerate at 10:30, the air conditioner has been continuously shut down for 0.5 hours. Taking one hour as the first time length as a reference, the continuous shutdown time of the air conditioner does not meet the standard of one hour of continuous shutdown. At this time, the air humidity value remains unchanged, that is, the air humidity value at 10:00 remains unchanged. Since the air humidity value at 10:00 is the air humidity value at 9:00, the target environment humidity value at 10:30 is the air humidity prediction value corresponding to 9:00.

[0083] That is, in the embodiment of the present application, the air conditioner corresponds to an initial humidity value after the first power-on refrigeration, and since the air conditioner is powered on for the first time, the initial humidity value at this time is the air humidity value at the last time corresponding to the time when the air conditioner is powered on for the first time. The target environment humidity value corresponding to the first power-on refrigeration of the air conditioner. With the change of time, the air conditioner may be restarted after continuous shutdown for the first time, or continuously run for the second time, at which time the target environment humidity value will change, but the initial humidity value corresponding to the first power-on refrigeration of the air conditioner and the time corresponding to the first power-on refrigeration of the air conditioner will change.

[0084] It should be noted that in the embodiment of the present application, the actual humidity value in the air will change with the change of time, so the air humidity prediction value given by the weather forecast will also change. Therefore, the obtained air humidity prediction value set can also be updated to obtain more accurate air humidity prediction values. At the same time, in the embodiment of the present application, since the humidity update period of the open scene is generally 1-2 hours, the air humidity prediction value set update period can also be 1-2 hours.

[0085] In the above embodiment, after determining the target environment humidity value, the air conditioner needs to be controlled for anti-condensation in the target time period according to the target environment humidity. As shown in Figure 4 The embodiment provided by the present application can include the following steps:

[0086] 41, obtaining a first humidity threshold and a second humidity threshold.

[0087] In the embodiment of the present application, whether to perform anti-condensation control is determined according to the humidity value; and determining whether to perform anti-condensation control according to the humidity value is actually determining the size relationship between the actual environment humidity and different humidity thresholds.

[0088] Specifically, the first humidity threshold range and the second humidity threshold range can be obtained; and the maximum humidity value in the first humidity threshold range is less than the minimum humidity value in the second humidity threshold range. Since the air humidity of each region is different in different time periods, the actual first humidity threshold and the second humidity threshold can be adjusted, that is, the first humidity threshold and the second humidity threshold are not fixed. In the embodiment of the present application, the first humidity threshold is actually determined in the first humidity threshold range according to the actual weather condition, and the second humidity threshold is determined in the second humidity threshold range.

[0089] In one specific embodiment of this application, the first humidity threshold range can be 65%-75%, and the second humidity threshold range can be 90-100%. The minimum humidity value in the second humidity threshold range is 90%, which is greater than the maximum humidity value of 75% in the first humidity threshold range. In this case, the first humidity threshold can be 70%, and the second humidity threshold can be 95%. At the same time, the actual values ​​of the first and second humidity thresholds can be changed under different weather conditions.

[0090] 42. Based on the target ambient humidity value, the first humidity threshold, and the second humidity threshold, determine whether the target ambient humidity value meets the preset anti-condensation conditions.

[0091] After obtaining the first humidity threshold and the second humidity threshold, the target ambient humidity value can be compared with the first threshold and the second threshold to determine whether the preset anti-condensation control conditions are met.

[0092] 43. If the conditions are met, then the air conditioner should be controlled to prevent condensation.

[0093] If the current target ambient humidity value meets the preset anti-condensation control conditions, then it means that the air conditioner needs to be controlled to prevent condensation.

[0094] like Figure 5 The diagram shown is a flowchart illustrating an embodiment of this application for determining whether anti-condensation control is required. In the above embodiment, determining whether preset anti-condensation control conditions are met based on the target ambient humidity value, a first humidity threshold, and a second humidity threshold may include:

[0095] 51. Determine whether the target ambient humidity value is greater than the first humidity threshold.

[0096] It should be noted that in the embodiments of this application, as the humidity level in the air increases, the air conditioner will perform cooling and other processes to reduce the humidity level. During the air conditioning cooling process, water vapor in the air will condense, so anti-condensation treatment is required. The prerequisite for water vapor in the air to condense is that the water vapor content in the air reaches a certain range, that is, the target ambient humidity level is greater than the first humidity threshold in the embodiments of this application.

[0097] 52. If the target ambient humidity value is greater than the first humidity threshold, then determine whether the target ambient humidity value is greater than the second humidity threshold.

[0098] If the target environment humidity value is greater than the first humidity threshold value, it indicates that the current target environment humidity value is already at a high level, and condensation will be generated during the use of the air conditioner, and the air conditioner needs to be controlled to prevent condensation. However, the specific operation of the air conditioner to prevent condensation is different when the target environment humidity value is in different ranges. Therefore, under the premise that the target environment humidity value is greater than the first humidity threshold value, it is also necessary to determine whether the target environment humidity value is greater than the second humidity threshold value.

[0099] 53、If the target environment humidity value is greater than the second humidity threshold value, the target environment humidity value meets the preset condensation prevention condition.

[0100] If the target environment humidity value is not only greater than the first humidity threshold value, but also greater than the second humidity threshold value, it indicates that the air humidity value is already very high at this time, and a large amount of condensation will be generated after the air conditioner works, and condensation prevention control is needed.

[0101] Specifically, in the embodiments of the present application, when the target environment humidity value is greater than the second humidity threshold value, the temperature difference at the air outlet of the air conditioner can be reduced by limiting the frequency of the air conditioner compressor, adjusting the angle of the air conditioner air deflector, and other means, so as to control the generation of condensation.

[0102] On the basis of the above-mentioned embodiments, if the target environment humidity value is less than the second humidity threshold value, it is also necessary to determine whether the target environment humidity value is less than the ideal humidity value after the air conditioner works for a third time length. If the target environment humidity value is not less than the ideal humidity value after the air conditioner works for a third time length, the target environment humidity value meets the preset condensation prevention judgment condition.

[0103] Specifically, in the embodiments of the present application, the judgment of the target environment humidity value, the first humidity threshold value and the second humidity threshold value is made on the premise that the air conditioner is powered on for the first time to refrigerate, or is continuously powered off for a first time length, or is continuously worked for a second time length. Therefore, the air conditioner is in a working state at this time, and the air conditioner in a working state will affect the environment humidity. At this time, the target environment humidity value is actually a predicted value obtained according to the weather forecast, so it is also necessary to compare the target environment humidity value with the ideal humidity value after the air conditioner works for a third time length.

[0104] In the embodiments of this application, after the air conditioner has been operating for three hours, the air humidity should theoretically drop to an ideal humidity level. If the actual air humidity has dropped to the ideal humidity level, then anti-condensation control is not required. However, the actual air humidity at this point is the aforementioned target ambient humidity level. Therefore, it is necessary to compare the target ambient humidity level with the ideal humidity level to determine whether the target ambient humidity level is lower than the ideal humidity level. If it is lower, it indicates that the air humidity is already at a low level, and anti-condensation control is not required. If the target ambient humidity level is still not lower than the ideal humidity level, it indicates that the air conditioner has not reduced the air humidity to a low level after operating for three hours, and anti-condensation control is still required.

[0105] It should be noted that in the embodiments of this application, the unit of the third operating time of the air conditioner is hours, and if the third operating time exceeds four hours, it is still calculated as four hours. That is, in the embodiments of this application, an air conditioner with an operating time of four hours or more will no longer affect the air humidity.

[0106] In one specific embodiment of this application, the ideal humidity value after the air conditioner has been operating for three hours can be: a*T1+RH1. Where a is usually the cooling humidity reduction coefficient, which can be determined experimentally, and a is usually 0.02-0.05.

[0107] RH1 is the first humidity threshold determined in this embodiment; T1 is the third operating time T1 of the air conditioner. It can be understood that a*T1 is the theoretically expected decrease in air humidity after the air conditioner has been operating for T1 hours, while a*T1+RH1 is the actual humidity value at this time, i.e., the ideal humidity value.

[0108] In the above embodiments, if the target ambient humidity is not less than the ideal humidity value after the air conditioner has been operating for three hours, then anti-condensation control is required. Since the ambient humidity at this time is greater than the first humidity threshold, and the air humidity has not decreased to the ideal humidity value after the air conditioner has been operating for T1 hours, this indicates that the air humidity is high, and the air conditioner is very prone to condensation during operation.

[0109] At this time, indoor and outdoor ambient temperatures can be obtained, and parameters such as the air conditioner's operating deflector can be used to determine whether the dew point temperature condition is met; if so, anti-condensation control can be achieved by reducing the air conditioner compressor frequency and adjusting the air conditioner deflector angle.

[0110] Dew point temperature refers to the temperature at which air reaches saturation under the premise that the water vapor content in the air remains constant and the air pressure is kept constant. It is the temperature at which water vapor and water reach equilibrium.

[0111] If the temperature has reached the dew point, which is the temperature at which water vapor turns into condensation, based on parameters such as indoor and outdoor air conditioning temperatures and the air conditioner's operating fan speed, and the air humidity is also at a high level, the water vapor in the air is very likely to turn into condensation. At this time, anti-condensation control must be implemented to prevent condensation from affecting the operation of the air conditioner.

[0112] like Figure 6 The diagram shown is a flowchart illustrating an embodiment of the air conditioning anti-condensation control method provided in this application. Figure 6 First, weather forecasts can be directly obtained through IoT modules and other devices to obtain humidity predictions for a preset time period; at this time, the air conditioner starts cooling. After the air conditioner starts, it needs to determine whether it is the first time it has been powered on for cooling, or whether it has been turned on after being shut down for a first period of time, or whether it has been running continuously for a second period of time; if not, the current humidity value remains unchanged; otherwise, the humidity value corresponding to this air conditioner operation needs to be updated. Figure 6 In the embodiment shown, the humidity value at this time is updated to the humidity value corresponding to the previous time in the weather forecast that is adjacent to the current time, and this humidity value is used as the target environmental humidity value at this time.

[0113] After determining the target ambient humidity value, it is necessary to determine whether to implement anti-condensation control. Specifically, a first humidity threshold and a second humidity threshold can be obtained, where the first humidity threshold is less than the second humidity threshold. It should be noted that, in the embodiments of this application, the humidity threshold is actually a range of the first humidity threshold and a range of the second humidity threshold; the maximum humidity value in the first humidity threshold range is less than the minimum humidity threshold in the second humidity threshold. For different weather conditions, the first humidity threshold is determined within the first humidity threshold range, and the second humidity threshold is determined within the second humidity threshold range before the final determination is made.

[0114] After determining the target ambient humidity value, the first humidity threshold, and the second humidity threshold, it can be determined whether anti-condensation control is needed based on the actual target ambient humidity value and humidity thresholds. Specifically, first determine if the target ambient humidity value is less than the first humidity threshold. If it is less, it indicates that the ambient humidity is at a low level, and anti-condensation control is not required. If the target ambient humidity value is greater than the first humidity threshold, it is also necessary to determine if the target ambient humidity value is less than the second humidity threshold.

[0115] If the target ambient humidity threshold is not less than the second humidity threshold, it indicates that the target ambient humidity is at a high level and anti-condensation control is required. Specifically, this can be achieved by limiting the air conditioner compressor frequency and adjusting the angle of the air conditioner deflector.

[0116] If the target environment humidity threshold is greater than the first humidity threshold and less than the second humidity threshold, the target environment humidity threshold also needs to be judged with the ideal humidity value. The ideal humidity value refers to a theoretical value of the air humidity reduction after the air conditioner runs for a third time length; specifically, it can be a*T1+RH1. Wherein, a is the cooling humidity reduction coefficient of the air conditioner, which can be determined by experiment; and T1 is the running time of the air conditioner, and more than four hours is calculated according to four hours; and RH1 is the first humidity threshold.

[0117] If the target environment humidity value is less than the theoretical humidity value, it means that the air humidity at this time is at a low level, and the air conditioner only performs ordinary cooling without condensation control. If the target environment humidity value is greater than the theoretical humidity value, it means that the air conditioner running does not reduce the air humidity value to the ideal level, and the air humidity value is still at a high level. At this time, the indoor and outdoor environment temperature, air conditioner running wind block and other conditions need to be obtained to determine whether the temperature at this time meets the dew point temperature; that is, whether the water vapor in the air is easy to condense into condensation. If it is satisfied, it means that the water vapor is easy to convert into condensation, and condensation control is needed; specifically, it can be prevented by limiting the frequency of the air conditioner compressor, adjusting the angle of the air deflector and other means.
