[0012] Secondly, embodiments of this application provide a humidification control device for controlling an air conditioner to humidify.

It controls the humidification rate of the humidification module and the rotation speed of the indoor fan, ensuring that these parameters match the current heating and humidity requirements. When the heat exchanger's capacity is weak, the humidification rate and the indoor fan speed can be reduced accordingly based on the current indoor humidity difference and the rate of change of indoor humidity. This improves the heat exchanger's capacity as quickly as possible while maintaining humidity comfort, thus ensuring thermal comfort. Conversely, when the heat exchanger's capacity is strong, the humidification rate and the indoor fan speed can be increased accordingly based on the current indoor humidity difference and the rate of change of indoor humidity. This causes the indoor humidity to rise synchronously with the indoor temperature, resulting in a warm and humid indoor environment. This effectively balances thermal and humidity comfort, significantly improving user comfort. Attached Figure Description

The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0033] like Figure 1 As shown, in a first aspect, embodiments of this application provide a humidification control method, which includes steps S10 to S30, for controlling an air conditioner 1 to humidify, which can better balance thermal comfort and humidity comfort, effectively improving user comfort. Here, the air conditioner 1 includes an indoor air duct, an indoor heat exchanger, an indoor fan, and a humidification module, which are respectively disposed in the indoor air duct; the type of air conditioner 1 can be determined according to actual needs, and can be, for example, a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, etc., which is not limited in this embodiment.

[0034] S10: In response to the air conditioner 1 being in heating mode, determine whether the humidification start conditions are met.

[0035] S20: In response to determining that the humidification start-up conditions are met, control the humidification module to start humidification.

[0036] S30: Based on the temperature of the indoor heat exchanger, the current indoor humidity difference, and the rate of change of indoor humidity, control the humidification rate of the humidification module and the speed of the indoor fan.

[0037] Here, the temperature of the indoor heat exchanger can be measured by a temperature sensor installed on the indoor heat exchanger, or determined by other methods of measurement or calculation; when the indoor heat exchanger has heat exchange coils, the temperature of the indoor heat exchanger can be the temperature of the heat exchange coils. The temperature of the indoor heat exchanger can characterize its heat exchange capacity; if the temperature of the indoor heat exchanger is higher, its heat exchange capacity is stronger; if the temperature of the indoor heat exchanger is lower, its heat exchange capacity is weaker.

[0038] The current indoor humidity difference is the difference between the set humidity and the current indoor humidity. It represents the magnitude and distance between the two humidity levels and can be negative, zero, or positive. The sign of the current indoor humidity difference indicates the magnitude of the difference between the two humidity levels, while the absolute value of the difference indicates the distance between them. A negative difference indicates that the current indoor humidity exceeds the set humidity; a zero difference indicates that the current indoor humidity is equal to the set humidity; a positive and small difference indicates that the current indoor humidity is close to the set humidity but has not yet reached it; a positive and large difference indicates that the current indoor humidity is far from the set humidity. The current indoor humidity can be measured in real time by a humidity sensor installed indoors. The humidity setting is the target humidity expected to be achieved in the indoor environment. It can be an input humidity value set by the user through a control terminal such as a remote control, control panel, or smart terminal, or it can be a comfortable humidity value automatically generated by the air conditioner 1 based on operating conditions such as the user's usage habits and current environmental information.

[0039] The rate of change of indoor humidity is used to characterize the current trend and speed of change in indoor humidity. Its value can be negative, zero, or positive. The sign of the rate of change indicates the current trend of indoor humidity change, while the absolute value of the rate of change indicates how quickly the indoor humidity changes. A negative rate of change indicates that the indoor humidity is gradually decreasing; a zero rate of change indicates that the indoor humidity remains constant; a positive and small rate of change indicates that the indoor humidity is slowly increasing; and a positive and large rate of change indicates that the indoor humidity is rapidly increasing.

[0040] Here, the humidification rate of the humidification module refers to the amount of water replenished to the indoor return air in the indoor air duct per unit time. If the humidification rate of the humidification module is high, the amount of water replenished to the indoor return air per unit time is large, and the humidification effect is more significant; conversely, if the humidification rate of the humidification module is low, the amount of water replenished to the indoor return air per unit time is small, and the humidification effect is weaker. The humidification rate of the humidification module is positively correlated with the temperature of the indoor heat exchanger and the current indoor humidity difference, and negatively correlated with the rate of change of indoor humidity. In other words, the humidification rate of the humidification module increases as the temperature of the indoor heat exchanger rises and decreases as the temperature of the indoor heat exchanger falls; the humidification rate of the humidification module increases as the current indoor humidity difference increases and decreases as the current indoor humidity difference decreases; and the humidification rate of the humidification module decreases as the rate of change of indoor humidity increases and increases as the rate of change of indoor humidity decreases.

[0041] In some embodiments, the control effect on the humidification rate of the humidification module can be considered in descending order of priority: the temperature of the indoor heat exchanger, the current indoor humidity difference, and the rate of change of indoor humidity. That is, the temperature of the indoor heat exchanger has the highest priority or the greatest influence on the humidification rate of the humidification module; the current indoor humidity difference has the next lowest priority or the next least influence; and the rate of change of indoor humidity has the next lowest priority or the next least influence. For example, the humidification rate of the humidification module is controlled first based on the temperature of the indoor heat exchanger, then based on the current indoor humidity difference, and finally based on the rate of change of indoor humidity. For example, the humidification rate of the humidification module can be comprehensively controlled by combining weighting coefficients with the temperature of the indoor heat exchanger, the current indoor humidity difference, and the rate of change of indoor humidity. For instance, a weighted calculation model for the humidification rate can be pre-established. This model takes the temperature of the indoor heat exchanger and its weighting coefficient, the current indoor humidity difference and its weighting coefficient, and the rate of change of indoor humidity and its weighting coefficient as inputs, and the humidification rate of the humidification module as the output. Among these, the weighting coefficient of the indoor heat exchanger temperature has the largest value, followed by the weighting coefficient of the indoor humidity difference, and the weighting coefficient of the rate of change of humidity has the smallest value.

[0042] In some examples, multiple inner pipe temperature ranges, sequentially distributed from smallest to largest, can be pre-set in the control system of air conditioner 1. For example, this may include at least three inner pipe temperature ranges: a first inner pipe temperature range greater than or equal to a first inner pipe temperature threshold and less than a second inner pipe temperature threshold; a second inner pipe temperature range greater than or equal to a second inner pipe temperature threshold and less than a third inner pipe temperature threshold; and a third inner pipe temperature range greater than or equal to a third inner pipe temperature threshold. The specific values ​​of the inner pipe temperature thresholds, such as the first, second, and third inner pipe temperature thresholds, can be determined according to actual needs, and this application embodiment does not limit this. For example, the first inner pipe temperature threshold can be 35–38°C, such as 35°C, 36°C, 37°C, or 38°C; the second inner pipe temperature threshold can be 42–45°C, such as 42°C, 43°C, 44°C, or 45°C; and the third inner pipe temperature threshold can be 49–52°C, such as 49°C, 50°C, 51°C, or 52°C. For each inner tube temperature range, multiple humidification rate values ​​can be set. Each humidification rate value corresponds to a current indoor humidity difference and an indoor humidity change rate. Any two humidification rate values ​​correspond to different current indoor humidity differences and / or different indoor humidity change rates. When the temperature of the indoor heat exchanger is within an inner tube temperature range, a specific value can be selected from the multiple humidification rate values ​​corresponding to that inner tube temperature range based on the current indoor humidity difference and indoor humidity change rate, and according to the aforementioned positive and negative correlations, to serve as the humidification rate of the humidification module. Here, the maximum humidification rate value corresponding to the first inner tube temperature range is less than the minimum humidification rate value corresponding to the second inner tube temperature range, the maximum humidification rate value corresponding to the second inner tube temperature range is less than the minimum humidification rate value corresponding to the third inner tube temperature range, and so on, with the maximum humidification rate value corresponding to the i-th inner tube temperature range being less than the minimum humidification rate value corresponding to the (i+1)-th inner tube temperature range.

[0043] Here, the indoor fan speed is positively correlated with the indoor heat exchanger temperature; that is, the indoor fan speed increases as the indoor heat exchanger temperature rises and decreases as the indoor heat exchanger temperature falls. For the control strategy of adjusting the indoor fan speed based on the current indoor humidity difference and the rate of change of indoor humidity, please refer to the following description. In some embodiments, the influence of the indoor fan speed on the control can be considered in descending order of priority: the indoor heat exchanger temperature, the current indoor humidity difference, and the rate of change of indoor humidity. Specifically, the indoor heat exchanger temperature has the highest priority or is the most influential factor on the indoor fan speed; the current indoor humidity difference has the next lowest priority or is the least influential factor; and the rate of change of indoor humidity has the next lowest priority or is the least influential factor. For example, the indoor fan speed is controlled first based on the indoor heat exchanger temperature, then based on the current indoor humidity difference, and finally based on the rate of change of indoor humidity. For example, the indoor fan speed can be comprehensively controlled by combining weighting coefficients with the indoor heat exchanger temperature, the current indoor humidity difference, and the indoor humidity change rate. For instance, a weighted calculation model for the indoor fan speed can be pre-established. This model uses the indoor heat exchanger temperature and its weighting coefficient, the current indoor humidity difference and its weighting coefficient, and the indoor humidity change rate and its weighting coefficient as inputs, and the indoor fan speed as the output. Among these, the indoor heat exchanger temperature weighting coefficient has the largest value, followed by the indoor humidity difference weighting coefficient, and the humidity change rate weighting coefficient has the smallest value.

[0044] In some examples, multiple inner pipe temperature ranges can be pre-set in the control system of air conditioner 1, sequentially distributed from smallest to largest. These ranges may include, for example, the aforementioned first inner pipe temperature range, second inner pipe temperature range, third inner pipe temperature range, etc. For each inner pipe temperature range, multiple indoor fan speed values ​​can be set. Each indoor fan speed value corresponds to a current indoor humidity difference and an indoor humidity change rate. Any two indoor fan speed values ​​correspond to different current indoor humidity differences and / or different indoor humidity change rates. When the temperature of the indoor heat exchanger is within an inner pipe temperature range, a specific value can be selected from the multiple indoor fan speed values ​​corresponding to that inner pipe temperature range based on the current indoor humidity difference and the indoor humidity change rate, to determine the indoor fan speed. Here, the maximum internal fan speed corresponding to the first internal pipe temperature range is less than the minimum internal fan speed corresponding to the second internal pipe temperature range, the maximum internal fan speed corresponding to the second internal pipe temperature range is less than the minimum internal fan speed corresponding to the third internal pipe temperature range, and so on, the maximum internal fan speed corresponding to the i-th internal pipe temperature range is less than the minimum internal fan speed corresponding to the (i+1)-th internal pipe temperature range.

[0045] Compared with related technologies, the humidification control method provided in this application can comprehensively consider the influence factors of the indoor heat exchanger temperature, the current indoor humidity difference, and the rate of change of indoor humidity, and control the humidification rate of the humidification module and the speed of the indoor fan, so that the humidification rate of the humidification module and the speed of the indoor fan can match the current heating demand and the current humidity demand. When the heat exchange capacity of the indoor heat exchanger is weak, the humidification rate of the humidification module and the speed of the indoor fan can be reduced to a corresponding degree according to the current indoor humidity difference and the rate of change of indoor humidity, so as to improve the heat exchange capacity of the indoor heat exchanger as quickly as possible while taking into account humidity comfort, thereby ensuring thermal comfort. When the heat exchange capacity of the indoor heat exchanger is strong, the humidification rate of the humidification module and the speed of the indoor fan can be increased to a corresponding degree according to the current indoor humidity difference and the rate of change of indoor humidity, so that the indoor humidity rises synchronously with the indoor temperature, thereby making the indoor environment warm and humid, and effectively improving the user's comfort by better balancing thermal comfort and humidity comfort.

[0046] like Figure 2 As shown, in some embodiments, S10 may include S11 to S13.

[0047] S11: Determine whether the temperature of the indoor heat exchanger is greater than or equal to the first inner tube temperature threshold and whether the current indoor humidity difference is greater than or equal to the first humidity difference threshold.

[0048] Here, the first inner tube temperature threshold can be referred to the above description, and will not be repeated here. The first humidity difference threshold can be preset in the control system of the air conditioner 1, and used as one of the judgment criteria for humidification start conditions.

[0049] S12: In response to determining that the temperature of the indoor heat exchanger is greater than or equal to the first inner tube temperature threshold and the current indoor humidity difference is greater than or equal to the first humidity difference threshold, determine that the humidification start condition is met.

[0050] When the temperature of the indoor heat exchanger is greater than or equal to the first inner pipe temperature threshold and the current indoor humidity difference is greater than or equal to the first humidity difference threshold, it can be determined that the air conditioner 1 is in heating operation and the temperature of the indoor heat exchanger has gradually increased. However, the current indoor humidity has not yet reached the set humidity and is far from the set humidity, so the indoor environment is prone to becoming dry, and it is necessary to control the humidification module to turn on for humidification. Therefore, it can be determined that the humidification activation conditions are met.

[0051] S13: In response to determining that the temperature of the indoor heat exchanger is less than the first inner tube temperature threshold or the current indoor humidity difference is less than the first humidity difference threshold, determine that the humidification start-up conditions are not met.

[0052] By setting S11 to S13, it is possible to accurately determine whether the humidification activation conditions are met, and then activate the humidification module in a timely manner when the air conditioner 1 is in heating mode, so as to humidify the indoor air in a timely manner, improve the humidity level of the indoor air, and thus improve the user's comfort.

[0053] like Figure 3 As shown, in some embodiments, S30 may include S31 to S33.

[0054] S31: Determine the temperature range of the inner tube within which the temperature of the indoor heat exchanger falls.

[0055] Here, multiple inner pipe temperature ranges, sequentially distributed from smallest to largest, can be pre-set in the control system of air conditioner 1. These ranges may include, for example, the aforementioned first inner pipe temperature range, second inner pipe temperature range, third inner pipe temperature range, etc. For each inner pipe temperature range, a speed control rule and multiple indoor fan speed values ​​can be set accordingly. Each indoor fan speed value corresponds to a current indoor humidity difference and an indoor humidity change rate based on the speed control rule. Any two indoor fan speed values ​​correspond to different current indoor humidity differences and / or different indoor humidity change rates. For example, a first speed control rule is set for the first inner pipe temperature range, a second speed control rule for the second inner pipe temperature range, a third speed control rule for the third inner pipe temperature range, and so on, with the i-th inner pipe temperature range corresponding to the i-th speed control rule.

[0056] S32: Determine the speed control rules for the indoor fan based on the temperature range of the inner tube where the indoor heat exchanger is located.

[0057] After determining the temperature range of the inner tube of the indoor heat exchanger, the speed control rule corresponding to the inner tube temperature range can be determined, and the speed control rule can be used as the speed control rule for the indoor fan.

[0058] S33: Control the speed of the indoor fan based on the current indoor humidity difference, the rate of change of indoor humidity, and the speed control rules of the indoor fan.

[0059] Within the inner pipe temperature range determined by S31, according to the indoor fan speed control rules determined by S32, an indoor fan speed value corresponding to the current indoor humidity difference and the indoor humidity change rate can be determined. Then, the indoor fan speed value is used as the target speed of the indoor fan, and the indoor fan speed is controlled according to the target speed.

[0060] like Figure 4 As shown, in some examples, S32 may include S321 to S323.

[0061] S321: In response to determining that the temperature of the indoor heat exchanger is within the first inner tube temperature range, the speed control rule of the indoor fan is determined to be the first speed control rule.

[0062] Here, the first speed control rule may include: the speed of the indoor fan is positively correlated with the rate of change of indoor humidity, the speed of the indoor fan is within the first speed range, and the speed of the indoor fan first increases and then decreases as the current indoor humidity difference decreases, and the maximum value of the first speed range is less than the standard speed value of the set fan speed of the indoor fan.

[0063] In other words, the multiple indoor fan speed values ​​set corresponding to the first inner pipe temperature range are all within the first speed range, and the maximum value among these multiple indoor fan speed values ​​is less than the standard speed value of the indoor fan's set fan speed setting. Here, the set fan speed setting of the indoor fan can be an input fan speed setting set by the user through a control terminal such as a remote control, control panel, or smart terminal, or it can be an automatic fan speed setting automatically generated by the air conditioner 1 based on operating conditions such as the user's usage habits and current environmental information. The set fan speed setting can be selected from multiple standard fan speed settings preset in the air conditioner 1. The standard fan speed settings can be, for example, the lowest fan speed setting, the second lowest fan speed setting, the medium fan speed setting, the second highest fan speed setting, and the highest fan speed setting. Each standard fan speed setting has a preset standard speed value. When the set fan speed setting is selected from the standard fan speed settings, the indoor fan usually operates at the standard speed value of the selected standard fan speed setting, which is used as the standard speed value of the set fan speed setting. Based on the first speed control rule, the indoor fan speed is controlled to operate at a reduced speed within a first speed range that is lower than the standard speed value of the set wind speed, and the indoor fan speed is controlled to be higher than the standard speed value of the next wind speed adjacent to the set wind speed, while the standard speed value of the next wind speed is lower than the standard speed value of the set wind speed; for example, when the set wind speed is set to medium wind speed, the next wind speed is the second lowest wind speed.

[0064] Meanwhile, when the indoor fan speed is selected within the first speed range, the indoor fan speed increases with the increase of the indoor humidity change rate and decreases with the decrease of the indoor humidity change rate. Furthermore, the indoor fan speed gradually increases to the first intermediate speed as the current indoor humidity difference decreases to, for example, a certain humidity difference or a certain humidity difference range, and gradually decreases from the first intermediate speed as the current indoor humidity difference continues to decrease from that humidity difference or humidity difference range. The first intermediate speed can be less than the standard speed value of the indoor fan's set fan speed.

[0065] S322: In response to determining that the temperature of the indoor heat exchanger is within the second inner tube temperature range, the speed control rule for the indoor fan is determined to be the second speed control rule.

[0066] Here, the second speed control rule may include: the speed of the indoor fan first increases and then decreases as the current indoor humidity difference decreases, and the speed of the indoor fan is within the second speed range. The minimum value of the second speed range is less than the standard speed value of the set fan speed of the indoor fan and greater than the maximum value of the first speed range. The maximum value of the second speed range is greater than the standard speed value of the set fan speed of the indoor fan.

[0067] In other words, the multiple internal fan speed values ​​set for the second internal pipe temperature range are all within the second speed range, and the minimum value among these multiple internal fan speed values ​​is less than the standard speed value of the indoor fan's set wind speed and greater than the maximum value of the first speed range, and the maximum value among these multiple internal fan speed values ​​is greater than the standard speed value of the indoor fan's set wind speed.

[0068] Meanwhile, when the indoor fan speed is selected within the second speed range, the indoor fan speed gradually increases to the second intermediate speed as the current indoor humidity difference decreases to a certain humidity difference or a certain humidity difference range, and gradually decreases from the second intermediate speed to a standard speed value lower than the set fan speed as the current indoor humidity difference continues to decrease from that humidity difference or humidity difference range; wherein, the second intermediate speed can be greater than or equal to the standard speed value of the set fan speed of the indoor fan.

[0069] Based on the second speed control rule, the indoor fan speed can be increased or decreased according to the actual operating conditions, based on the standard speed value of the set fan speed. When the indoor fan speed is increased, it is lower than the standard speed value of the previous fan speed adjacent to the set fan speed. When the fan speed is decreased, it is higher than the standard speed value of the next fan speed adjacent to the set fan speed. The standard speed value of the previous fan speed is greater than the standard speed value of the set fan speed, and the standard speed value of the next fan speed is less than the standard speed value of the set fan speed. For example, when the set fan speed is set to medium, the next fan speed is the second lowest, and the previous fan speed is the second highest.

[0070] S323: In response to determining that the temperature of the indoor heat exchanger is within the third inner tube temperature range, the speed control rule for the indoor fan is determined to be the third speed control rule.

[0071] Here, the third speed control rule may include: the speed of the indoor fan first increases and then decreases as the current indoor humidity difference decreases, and the speed of the indoor fan is within the third speed range, and the minimum value of the third speed range is greater than or equal to the standard speed value of the set fan speed of the indoor fan.

[0072] In other words, the multiple internal fan speed values ​​set for the third internal pipe temperature range are all within the third speed range, and the minimum value among these multiple internal fan speed values ​​is greater than or equal to the standard speed value of the indoor fan's set wind speed.

[0073] Meanwhile, when the indoor fan speed is within the third speed range, the indoor fan speed gradually increases to the third intermediate speed as the current indoor humidity difference decreases to a certain humidity difference or a certain humidity difference range, and gradually decreases from the third intermediate speed as the current indoor humidity difference continues to decrease from that humidity difference or humidity difference range; wherein, the third intermediate speed can be greater than the standard speed value of the indoor fan's set fan speed.

[0074] Based on the third speed control rule, the indoor fan speed can be increased according to the actual working conditions based on the standard speed value of the set wind speed. When the indoor fan speed is increased, it is lower than the standard speed value of the wind speed of the previous wind speed adjacent to the set wind speed, and the standard speed value of the previous wind speed is greater than the standard speed value of the set wind speed. For example, when the set wind speed is set to medium wind speed, the previous wind speed is the second highest wind speed.

[0075] like Figure 5 As shown, for example, the second speed control rule may also include S3221 to S3222.

[0076] S3221: In response to determining that the current indoor humidity difference is within the first humidity difference range, determine that the indoor fan speed is positively correlated with the rate of change of indoor humidity, and that the indoor fan speed is less than or equal to the standard speed value of the indoor fan's set damper.

[0077] Here, multiple humidity difference ranges, sequentially distributed from largest to smallest, can be pre-set in the control system of the air conditioner 1. For example, this may include at least three humidity difference ranges: a first humidity difference range greater than or equal to a first humidity difference threshold, a second humidity difference range less than the first humidity difference threshold but greater than or equal to a second humidity difference threshold, and a third humidity difference range less than the second humidity difference threshold but greater than or equal to a third humidity difference threshold. The specific values ​​of the humidity difference thresholds, such as the first, second, and third humidity difference thresholds, can be determined according to actual needs, and this embodiment does not limit this. For example, the first humidity difference threshold can be 15% to 20%, such as 15%, 16%, 17%, 18%, 19%, or 20%. For example, the second humidity difference threshold can be 0% to 2%, such as 0%, 1%, or 2%. For example, the third humidity difference threshold can be -8% to -5%, such as -8%, -7%, -6%, or -5%.

[0078] Within the first humidity difference range, the second speed control rule may further include: the indoor fan speed is positively correlated with the rate of change of indoor humidity, and the indoor fan speed is less than or equal to the standard speed value of the set fan speed. In other words, the indoor fan speed is controlled to increase as the rate of change of indoor humidity increases and decrease as the rate of change of indoor humidity decreases, and the indoor fan speed is controlled to decelerate based on the standard speed value of the set fan speed. Furthermore, during deceleration, the indoor fan speed is controlled to be higher than the standard speed value of the next fan speed adjacent to the set fan speed, and the standard speed value of the next fan speed is lower than the standard speed value of the set fan speed; for example, when the set fan speed is medium, the next fan speed is the second lowest.

[0079] S3222: In response to determining that the current indoor humidity difference is within the second humidity difference range, determine that the indoor fan speed is negatively correlated with the rate of change of indoor humidity, and that the indoor fan speed is greater than the standard speed value of the indoor fan's set damper.

[0080] Within the second humidity difference range, the second speed control rule may further include: the indoor fan speed is negatively correlated with the rate of change of indoor humidity, and the indoor fan speed is greater than the standard speed value of the set fan speed. In other words, the indoor fan speed is controlled to decrease as the rate of change of indoor humidity increases and increase as the rate of change of indoor humidity decreases, and the indoor fan speed is controlled to increase based on the standard speed value of the set fan speed, and the indoor fan speed is controlled to be lower than the standard speed value of the previous fan speed adjacent to the set fan speed during the increased speed operation, while the standard speed value of the previous fan speed is greater than the standard speed value of the set fan speed; for example, when the set fan speed is medium, the previous fan speed is the second-lowest fan speed.

[0081] S3223: In response to determining that the current indoor humidity difference is in the third humidity difference range, determine that the indoor fan speed is negatively correlated with the rate of change of indoor humidity, and that the indoor fan speed is greater than or equal to the standard speed value of the indoor fan's set damper.

[0082] Within the third humidity difference range, the second speed control rule may further include: the indoor fan speed is negatively correlated with the rate of change of indoor humidity, and the indoor fan speed is greater than or equal to the standard speed value of the set fan speed. In other words, the indoor fan speed is controlled to decrease as the rate of change of indoor humidity increases and increase as the rate of change of indoor humidity decreases, and the indoor fan speed is controlled to remain constant or increase based on the standard speed value of the set fan speed, and the indoor fan speed is controlled to be lower than the standard speed value of the previous fan speed adjacent to the set fan speed when increasing speed, and the standard speed value of the previous fan speed is greater than the standard speed value of the set fan speed; for example, when the set fan speed is medium, the previous fan speed is the second-lowest fan speed.

[0083] By setting S3221 to S3223, the current humidification demand can be accurately predicted within the second inner tube temperature range based on the current indoor humidity difference and the rate of change of indoor humidity. Then, the humidification rate of the humidification module and the speed of the indoor fan can be adjusted in real time according to the current humidification demand, so as to better meet the humidification demand, while taking into account thermal comfort and humidity comfort, and improving the user's comfort.

[0084] like Figure 6 As shown, for example, the third speed control rule may also include S3231 to S3233.

[0085] S3231: In response to determining that the current indoor humidity difference is within the first humidity difference range, determine that the indoor fan speed remains unchanged and that the indoor fan speed is greater than the standard speed value of the indoor fan's set windshield.

[0086] Here, multiple humidity difference intervals that are continuously distributed in ascending order can be preset in the control system of the air conditioner 1. For example, at least three humidity difference intervals can be included, such as the first humidity difference interval, the second humidity difference interval, and the third humidity difference interval.

[0087] Within the first humidity difference range, the third speed control rule may further include: maintaining a constant indoor fan speed, and ensuring the indoor fan speed is greater than the standard speed value of the set fan speed setting. In other words, controlling the indoor fan speed to increase from the standard speed value of the set fan speed setting, and maintaining a constant speed at the increased speed. The increased speed is lower than the standard speed value of the previous fan speed setting adjacent to the set fan speed setting, and the standard speed value of the previous fan speed setting is greater than the standard speed value of the set fan speed setting; for example, when the set fan speed setting is medium, the previous fan speed setting is the second-lowest.

[0088] S3232: In response to determining that the current indoor humidity difference is within the second humidity difference range, determine that the indoor fan speed is negatively correlated with the rate of change of indoor humidity, and that the indoor fan speed is greater than or equal to the standard speed value of the indoor fan's set damper.

[0089] Within the second humidity difference range, the third speed control rule may further include: the indoor fan speed is negatively correlated with the rate of change of indoor humidity, and the indoor fan speed is greater than or equal to the standard speed value of the set fan speed. In other words, the indoor fan speed is controlled to decrease as the rate of change of indoor humidity increases and increase as the rate of change of indoor humidity decreases, and the indoor fan speed is controlled to remain constant or increase based on the standard speed value of the set fan speed, and the indoor fan speed is controlled to be lower than the standard speed value of the previous fan speed adjacent to the set fan speed when increasing speed, and the standard speed value of the previous fan speed is greater than the standard speed value of the set fan speed; for example, when the set fan speed is medium, the previous fan speed is the second-lowest fan speed.

[0090] S3233: In response to determining that the current indoor humidity difference is in the third humidity difference range, determine that the indoor fan speed is negatively correlated with the rate of change of indoor humidity, and that the indoor fan speed is greater than the standard speed value of the indoor fan's set damper.

[0091] Within the third humidity difference range, the third speed control rule may also include: the indoor fan speed is negatively correlated with the rate of change of indoor humidity, and the indoor fan speed is greater than the standard speed value of the set fan speed. In other words, the indoor fan speed is controlled to decrease as the rate of change of indoor humidity increases and increase as the rate of change of indoor humidity decreases, and the indoor fan speed is controlled to increase from the standard speed value of the set fan speed, and the indoor fan speed is controlled to be lower than the standard speed value of the previous fan speed adjacent to the set fan speed during the increased speed operation, while the standard speed value of the previous fan speed is greater than the standard speed value of the set fan speed; for example, when the set fan speed is medium, the previous fan speed is the second-lowest fan speed.

[0092] By setting S3231 to S3233, the current humidification demand can be accurately predicted within the third inner tube temperature range based on the current indoor humidity difference and the rate of change of indoor humidity. Then, the humidification rate of the humidification module and the speed of the indoor fan can be adjusted in real time according to the current humidification demand, so as to better meet the humidification demand, while taking into account thermal comfort and humidity comfort, and improving the user's comfort.

[0093] In some embodiments, the humidification module may include a water supply container, a humidification container, a humidification head, a first water pump, a second water pump, a first water level sensor, and a second water level sensor. The water supply container, the humidification container, and the humidification head are sequentially connected via water channels. The first water pump and the first water level sensor are respectively disposed within the water supply container. The first water pump is used to pump water from the water supply container into the humidification container to replenish the humidification container. The second water pump and the second water level sensor are respectively disposed within the humidification container. The second water pump is used to pump water from the humidification container to the humidification head. The type of humidification head can be determined according to actual needs, and may include microporous humidification nozzles, ultrasonic atomizers, etc. This application embodiment does not limit this type. Figure 7 As shown, the humidification control method may include 41 to S43.

[0094] S41: Obtain the measured water level from the first water level sensor and the measured water level from the second water level sensor.

[0095] S42: Control the operation of the first water pump based on the water level measured by the first water level sensor.

[0096] Here, the maximum water replenishment level, the warning water replenishment level, and the anti-dry-pump level can be preset. The maximum water replenishment level is the maximum water level in the water replenishment container; if the maximum water replenishment level is exceeded, water replenishment to the water replenishment container will stop. The warning water replenishment level is the critical water level that reminds the user to manually replenish the water replenishment container or to control the water replenishment device to automatically replenish the water replenishment container. If the water level is lower than the warning water replenishment level, the user will be reminded to manually replenish the water replenishment container or to control the water replenishment device to automatically replenish the water replenishment container. The anti-dry-pump level is the critical water level at which the water replenishment container supplies water to the humidification container; if the water level is lower than the anti-dry-pump level, the first water pump will stop working, and the water replenishment container will not supply water to the humidification container.

[0097] In this way, when the water level measured by the first water level sensor is lower than the anti-dry-pumping water level, the first water pump can be controlled to stop working, and the user can be reminded to manually replenish the water supply container or to automatically replenish the water supply container by the water supply device; when the water level measured by the first water level sensor is lower than the warning water supply water level, the user can be reminded to manually replenish the water supply container or to automatically replenish the water supply container by the water supply device, and the first water pump can continue to pump water from the water supply container into the humidification container; when the water level measured by the first water level sensor reaches the maximum water supply water level, the user can be reminded to stop replenishing the water supply container or to stop the water supply device from automatically replenishing the water supply container.

[0098] S43: Control the operation of the second water pump based on the water level measured by the second water level sensor.

[0099] Here, the maximum humidification water level, the warning humidification water level, and the water shortage shutdown water level can be preset. The maximum humidification water level is the maximum water level in the humidification container. When the maximum humidification water level is exceeded, the first water pump will stop replenishing water to the humidification container. The warning humidification water level is the critical water level that reminds the user to manually replenish water to the humidification container or controls the first water pump to automatically replenish water to the humidification container. When the water level is below the warning humidification water level, the user will be reminded to manually replenish water to the humidification container or the first water pump will automatically replenish water to the humidification container. The water shortage shutdown water level is the critical water level that the humidification container supplies water to the humidification head. When the water level is below the water shortage shutdown water level, the second water pump will stop working, and the humidification container will not supply water to the humidification head.

[0100] Thus, when the water level measured by the second water level sensor falls below the water shortage shutdown level, the second water pump can be controlled to stop working, and the user can be reminded to manually add water to the humidification container, or the first water pump can be controlled to automatically add water to the humidification container. When the water level measured by the second water level sensor falls below the warning humidification water level, the user can be reminded to manually add water to the humidification container, or the first water pump can be controlled to automatically add water to the humidification container. The second water pump can continue to pump water from the humidification container into the humidification head. If the second water pump is a variable frequency pump, it can be controlled to operate at the lower frequency limit to prolong the time before the water volume in the humidification container decreases. When the water level measured by the second water level sensor reaches the maximum humidification water level, the user can be reminded to stop adding water to the humidification container, or the first water pump can be controlled to stop automatically adding water to the humidification container.

[0101] like Figure 8 As shown, in some embodiments, the humidification control method may include S50.

[0102] S50: In response to the air conditioner 1 being in independent humidification mode, the humidification rate of the humidification module is controlled according to the current indoor humidity difference and the rate of change of indoor humidity.

[0103] When air conditioner 1 is in independent humidification mode, it only provides humidification but not cooling or heating. Here, the humidification rate of the humidification module is positively correlated with the current indoor humidity difference, and negatively correlated with the rate of change of indoor humidity. In other words, the humidification rate of the humidification module increases as the current indoor humidity difference increases and decreases as the current indoor humidity difference decreases, and the speed of the indoor fan decreases as the rate of change of indoor humidity increases and increases as the rate of change of indoor humidity decreases.

[0104] Secondly, embodiments of this application provide a humidification control device for controlling the air conditioner 1 to humidify.

The general-purpose processor can be a microprocessor or any conventional processor, and can be based on x86 architecture or ARM architecture.

The water supply container, the humidification container, and the humidification head are sequentially connected by water channels. The first water pump and the first water level sensor are respectively disposed in the water supply container, and the second water pump and the second water level sensor are respectively disposed in the humidification container. The type of humidification head can be determined according to actual needs, and may include microporous humidification nozzles, ultrasonic atomizers, etc. This application embodiment does not limit this type.

[0109] Fourthly, embodiments of this application provide a computer-readable storage medium having a computer program stored thereon, the computer program being loaded by a processor 10 to execute the steps in the control method of any of the above embodiments.
