[0032] In this application, the word "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0033] like Figure 1 As shown, in the first aspect, the embodiment of the present application provides a humidification control method, which includes S10 to S30, and is used to control the air conditioner 1 to humidify, which can better take into account thermal comfort and humidity comfort, and effectively improve the user's comfort. Here, the air conditioner 1 includes an indoor air duct, an indoor heat exchanger, an indoor fan and a humidification module, and the indoor heat exchanger, the indoor fan and the humidification module are respectively arranged in the indoor air duct; the type of the air conditioner 1 can be determined according to actual needs, and can adopt types such as wall-mounted air conditioners, cabinet air conditioners, window air conditioners, etc., and the embodiment of the present application does not limit this.

[0034] S10: In response to the air conditioner 1 being in the heating mode, determining whether a humidification on condition is satisfied.

[0035] S20: In response to determining that the humidification start condition is met, controlling the humidification module to start humidification.

[0036] S30: Controlling the humidification rate of the humidification module and the rotation speed of the indoor fan according to the temperature of the indoor heat exchanger, the current indoor humidity difference and the indoor humidity change rate.

[0037] Here, the temperature of the indoor heat exchanger can be measured by a temperature sensor disposed on the indoor heat exchanger, or can be measured or calculated in other ways; when the indoor heat exchanger has a heat exchange coil, the temperature of the indoor heat exchanger can be the temperature of the heat exchange coil. The temperature of the indoor heat exchanger can represent the heat exchange capacity of the indoor heat exchanger; if the temperature of the indoor heat exchanger is high, the heat exchange capacity of the indoor heat exchanger is strong; if the temperature of the indoor heat exchanger is low, the heat exchange capacity of the indoor heat exchanger is weak.

[0038] The current indoor humidity difference is the difference between the set humidity and the current indoor humidity, which is used to characterize the magnitude relationship and distance between the current indoor humidity and the set humidity. Its value can be negative, zero or positive; the sign of the current indoor humidity difference characterizes the magnitude relationship between the current indoor humidity and the set humidity, and the absolute value of the current indoor humidity difference characterizes the distance between the current indoor humidity and the set humidity. If the current indoor humidity difference is a negative value, it indicates that the current indoor humidity has exceeded the set humidity; if the current indoor humidity difference is zero, it indicates that the current indoor humidity is equal to the set humidity; if the current indoor humidity difference is a positive value and the value is small, it indicates that the current indoor humidity is closer to the set humidity but has not yet reached the set humidity; if the current indoor humidity difference is a positive value and the value is large, it indicates that the current indoor humidity has not yet reached the set humidity and is far from the set humidity. Here, the current indoor humidity can be measured in real time by a humidity sensor set on the indoor side. The set humidity 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, a control panel, or a 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, current environmental information, etc.

[0039] The indoor humidity change rate is used to characterize the current trend and speed of change of indoor humidity. Its value can be negative, zero or positive. The sign of the indoor humidity change rate characterizes the current trend of change of indoor humidity, and the absolute value of the indoor humidity change rate characterizes the speed of change of indoor humidity. If the indoor humidity change rate is negative, it indicates that the current indoor humidity is gradually decreasing; if the indoor humidity change rate is zero, it indicates that the current indoor humidity remains unchanged; if the indoor humidity change rate is positive and the value is small, it indicates that the current indoor humidity is slowly rising; if the indoor humidity change rate is positive and the value is large, it indicates that the current indoor humidity is rising rapidly.

[0040] Here, the humidification rate of the humidification module refers to the amount of water replenished by the humidification module to the indoor return air in the indoor air duct per unit time. If the humidification rate of the humidification module is large, the amount of water replenished by 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 small, the amount of water replenished by the indoor return air per unit time is small, and the humidification effect is relatively weak. 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 indoor humidity change rate; in other words, the humidification rate of the humidification module is controlled to increase with the increase of the temperature of the indoor heat exchanger and decrease with the decrease of the temperature of the indoor heat exchanger, the humidification rate of the humidification module is controlled to increase with the increase of the current indoor humidity difference and decrease with the decrease of the current indoor humidity difference, and the humidification rate of the humidification module is controlled to decrease with the increase of the indoor humidity change rate and increase with the decrease of the indoor humidity change rate.

[0041] In some embodiments, the control influence on the humidification rate of the humidification module can be considered in descending order of priority of the temperature of the indoor heat exchanger, the current indoor humidity difference, and the indoor humidity change rate, that is, the influence of the temperature of the indoor heat exchanger on the humidification rate of the humidification module has the highest priority or the largest influencing factor, the influence of the current indoor humidity difference on the humidification rate of the humidification module has the second highest priority or the second largest influencing factor, and the influence of the indoor humidity change rate on the humidification rate of the humidification module has the third highest priority or the third largest influencing factor. Exemplarily, the humidification rate of the humidification module is controlled first according to the temperature of the indoor heat exchanger, secondly according to the current indoor humidity difference, and thirdly according to the indoor humidity change rate. As another example, the humidification rate of the humidification module can be comprehensively controlled in combination with the weight coefficient and the temperature of the indoor heat exchanger, the current indoor humidity difference and the indoor humidity change rate. For example, a humidification rate weighted calculation model is established in advance. The humidification rate weighted calculation model takes the temperature of the indoor heat exchanger and the indoor heat exchanger temperature weight coefficient, the current indoor humidity difference and the indoor humidity difference weight coefficient, the indoor humidity change rate and the humidity change rate weight coefficient as input, and takes the humidification rate of the humidification module as the output result; among them, the indoor heat exchanger temperature weight coefficient has the largest value, the indoor humidity difference weight coefficient is the second, and the humidity change rate weight coefficient is the smallest.

[0042] In some examples, a plurality of inner tube temperature intervals which are continuously distributed from small to large can be pre-set in the control system of the air conditioner 1, for example, a first inner tube temperature interval which is greater than or equal to the first inner tube temperature threshold and less than the second inner tube temperature threshold, a second inner tube temperature interval which is greater than or equal to the second inner tube temperature threshold and less than the third inner tube temperature threshold, and a third inner tube temperature interval which is greater than or equal to the third inner tube temperature threshold, etc., at least three inner tube temperature intervals. The specific values ​​of the inner tube temperature thresholds such as the first inner tube temperature threshold, the second inner tube temperature threshold and the third inner tube temperature threshold can be determined according to actual needs, and the embodiment of the present application does not limit this; for example, the first inner tube temperature threshold can be 35-38°C, for example, different values ​​such as 35°C, 36°C, 37°C or 38°C; for example, the second inner tube temperature threshold can be 42-45°C, for example, different values ​​such as 42°C, 43°C, 44°C or 45°C; for example, the third inner tube temperature threshold can be 49-52°C, for example, different values ​​such as 49°C, 50°C, 51°C or 52°C. For each inner tube temperature interval, multiple humidification rate values ​​can be set accordingly, each humidification rate value corresponds to a current indoor humidity difference and an indoor humidity change rate, and 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 interval, a specific value can be selected from the multiple humidification rate values ​​corresponding to the inner tube temperature interval based on the current indoor humidity difference and the indoor humidity change rate, and based on the above-mentioned positive correlation and negative correlation, as the humidification rate of the humidification module. Here, the maximum humidification rate value corresponding to the first inner tube temperature interval is less than the minimum humidification rate value corresponding to the second inner tube temperature interval, and the maximum humidification rate value corresponding to the second inner tube temperature interval is less than the minimum humidification rate value corresponding to the third inner tube temperature interval; and so on, the maximum humidification rate value corresponding to the i-th inner tube temperature interval is less than the minimum humidification rate value corresponding to the i+1-th inner tube temperature interval.

[0043] Here, the speed of the indoor fan is positively correlated with the temperature of the indoor heat exchanger, that is, the speed of the indoor fan is controlled to increase as the temperature of the indoor heat exchanger rises, and decreases as the temperature of the indoor heat exchanger decreases. As for the control strategy of the speed of the indoor fan following the current indoor humidity difference and the indoor humidity change rate, please refer to the following introduction. In some embodiments, the control influence on the speed of the indoor fan can be considered in order of decreasing priority of the temperature of the indoor heat exchanger, the current indoor humidity difference and the indoor humidity change rate, that is, the influence of the temperature of the indoor heat exchanger on the speed of the indoor fan has the highest priority or the largest influencing factor, the influence of the current indoor humidity difference on the speed of the indoor fan has the second highest priority or the second highest influencing factor, and the influence of the indoor humidity change rate on the speed of the indoor fan has the second highest priority or the second highest influencing factor. Exemplarily, the speed of the indoor fan is controlled first according to the temperature of the indoor heat exchanger, secondly according to the current indoor humidity difference, and thirdly according to the indoor humidity change rate. The speed of the indoor fan is controlled. As another example, the speed of the indoor fan can be comprehensively controlled in combination with the weight coefficient and the temperature of the indoor heat exchanger, the current indoor humidity difference and the indoor humidity change rate. For example, a weighted calculation model for the indoor fan speed is established in advance. The weighted calculation model for the indoor fan speed takes the temperature of the indoor heat exchanger and the indoor heat exchanger temperature weight coefficient, the current indoor humidity difference and the indoor humidity difference weight coefficient, the indoor humidity change rate and the humidity change rate weight coefficient as input, and takes the speed of the indoor fan as output; among them, the value of the indoor heat exchanger temperature weight coefficient is the largest, the value of the indoor humidity difference weight coefficient is the second, and the value of the humidity change rate weight coefficient is the smallest.

[0044] In some examples, a plurality of inner tube temperature intervals which are continuously distributed from small to large can be pre-set in the control system of the air conditioner 1, for example, the first inner tube temperature interval, the second inner tube temperature interval, the third inner tube temperature interval and the like can be included. For each inner tube temperature interval, a plurality of inner fan speed values ​​can be set correspondingly, each inner fan speed value corresponds to a current indoor humidity difference and an indoor humidity change rate, and the current indoor humidity difference and / or the indoor humidity change rate corresponding to any two inner fan speed values ​​are different; when the temperature of the indoor heat exchanger is within an inner tube temperature interval, a specific value can be selected from the plurality of inner fan speed values ​​corresponding to the inner tube temperature interval according to the current indoor humidity difference and the indoor humidity change rate, as the speed of the indoor fan. Here, the maximum inner fan speed value corresponding to the first inner tube temperature interval is less than the minimum inner fan speed value corresponding to the second inner tube temperature interval, and the maximum inner fan speed value corresponding to the second inner tube temperature interval is less than the minimum inner fan speed value corresponding to the third inner tube temperature interval; and so on, the maximum inner fan speed value corresponding to the i-th inner tube temperature interval is less than the minimum inner fan speed value corresponding to the i+1-th inner tube temperature interval.

[0045] Compared with the related art, the humidification control method provided in the embodiment of the present application can comprehensively consider the influencing factors of the temperature of the indoor heat exchanger, the current indoor humidity difference and the indoor humidity change rate, 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 controlled to be reduced to a corresponding extent according to the current indoor humidity difference and the indoor humidity change rate, so as to improve the heat exchange capacity of the indoor heat exchanger as soon as possible while taking into account the 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 controlled to be increased to a corresponding extent according to the current indoor humidity difference and the indoor humidity change rate, so that the indoor humidity rises synchronously with the indoor temperature, thereby making the indoor environment warm and humid, better taking into account thermal comfort and humidity comfort, and effectively improving the user's comfort.

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

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

[0048] Here, the first inner tube temperature threshold can refer to the above introduction, which will not be repeated here. The first humidity difference threshold can be pre-set in the control system of the air conditioner 1 and used as one of the judgment marks for the humidification start condition.

[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, determining that the humidification start condition is met.

[0050] When it is determined 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, it can be determined that the air conditioner 1 is in the heating operation process and the temperature of the indoor heat exchanger has gradually increased, and 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 become dry, and the humidification module needs to be controlled to turn on for humidification. Therefore, it can be determined that the humidification turn-on condition is 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, determining that the humidification start condition is not satisfied.

[0052] By setting S11 to S13, it is possible to more accurately determine whether the humidification start-up conditions are met, and then promptly turn on the humidification module when the air conditioner 1 is in heating operation, so as to humidify the indoor air in time, improve the humidity of the indoor air, and thus improve the user's comfort.

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

[0054] S31: Determine the inner tube temperature range in which the temperature of the indoor heat exchanger is located.

[0055] Here, a plurality of inner tube temperature intervals which are continuously distributed from small to large can be pre-set in the control system of the air conditioner 1, for example, the first inner tube temperature interval, the second inner tube temperature interval, the third inner tube temperature interval and the like can be included. For each inner tube temperature interval, a speed control rule and a plurality of inner fan speed values ​​can be set accordingly, and each inner fan speed value corresponds to a current indoor humidity difference and an indoor humidity change rate based on the speed control rule, and the current indoor humidity difference corresponding to any two inner fan speed values ​​is different and / or the indoor humidity change rate is different. For example, the first inner tube temperature interval corresponds to the setting of the first speed control rule, the second inner tube temperature interval corresponds to the setting of the second speed control rule, and the third inner tube temperature interval corresponds to the setting of the third speed control rule; and so on, the i-th inner tube temperature interval corresponds to the setting of the i-th speed control rule.

[0056] S32: Determine a speed control rule of the indoor fan according to the inner tube temperature range in which the temperature of the indoor heat exchanger is located.

[0057] After determining the inner tube temperature interval in which the temperature of the indoor heat exchanger is located, a speed control rule corresponding to the inner tube temperature interval can be determined according to the inner tube temperature interval, and the speed control rule is used as the speed control rule of the indoor fan.

[0058] S33: Controlling the speed of the indoor fan according to the current indoor humidity difference, the indoor humidity change rate and the speed control rule of the indoor fan.

[0059] Within the inner tube temperature range determined by S31, according to the indoor fan speed control rule determined by S32, an indoor fan speed value corresponding to the current indoor humidity difference and the indoor humidity change rate can be determined, and then the indoor fan speed value is used as the target speed of the indoor fan, so as to control the speed of the indoor fan 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 in the first inner tube temperature range, determining that the speed control rule of the indoor fan is 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 a 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 wind speed of the indoor fan.

[0063] In other words, the multiple internal fan speed values ​​corresponding to the first internal tube temperature interval are all within the first speed range, and the maximum value of the multiple internal fan speed values ​​is less than the standard speed value of the set wind speed of the indoor fan. Here, the set wind speed of the indoor fan can be an input wind speed set by the user through a control terminal such as a remote control, a control panel, an intelligent terminal, or an automatic wind speed automatically generated by the air conditioner 1 according to operating conditions such as the user's usage habits and current environmental information; the set wind speed can be selected from a plurality of standard wind speeds pre-set in the air conditioner 1, and the standard wind speed can be, for example, the lowest wind speed, the second lowest wind speed, the middle wind speed, the second highest wind speed and the highest wind speed, and each standard wind speed is pre-set with a standard speed value; when the set wind speed is selected from the standard wind speed, the indoor fan usually operates according to the standard speed value of the selected standard wind speed, which is used as the standard speed value of the set wind speed. Based on the first speed control rule, that is, the speed of the indoor fan is controlled to be reduced within a first speed range that is lower than the standard speed value of the set wind speed, and the speed of the indoor fan is controlled to be higher than the standard speed value of the next wind speed adjacent to the set wind speed, and the standard speed value of the next wind speed is less than the standard speed value of the set wind speed; for example, when the set wind speed is the medium wind speed, the next wind speed is the second lowest wind speed.

[0064] At the same time, when the speed of the indoor fan is taken within the first speed range, the speed of the indoor fan increases with the increase of the indoor humidity change rate, and decreases with the decrease of the indoor humidity change rate, and the speed of the indoor fan gradually increases to a first intermediate speed in the process of the current indoor humidity difference decreasing to, for example, a certain humidity difference or a certain humidity difference interval, and gradually decreases from the first intermediate speed in the process of the current indoor humidity difference continuing to decrease from the humidity difference or the humidity difference interval; wherein, the first intermediate speed may be less than the standard speed value of the set wind speed of the indoor fan.

[0065] S322: In response to determining that the temperature of the indoor heat exchanger is in the second inner tube temperature range, determining that the speed control rule of the indoor fan is 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 a second speed range, the minimum value of the second speed range is less than the standard speed value of the set wind speed of the indoor fan and greater than the maximum value of the first speed range, and the maximum value of the second speed range is greater than the standard speed value of the set wind speed of the indoor fan.

[0067] In other words, the multiple internal fan speed values ​​corresponding to the second internal tube temperature interval are all within the second speed range, and the minimum value of the multiple internal fan speed values ​​is less than the standard speed value of the set wind speed of the indoor fan and greater than the maximum value of the first speed range, and the maximum value of the multiple internal fan speed values ​​is greater than the standard speed value of the set wind speed of the indoor fan.

[0068] At the same time, when the speed of the indoor fan is taken within the second speed range, the speed of the indoor fan gradually increases to the second intermediate speed in the process of the current indoor humidity difference decreasing to a certain humidity difference or a certain humidity difference interval, and gradually decreases from the second intermediate speed to a standard speed value less than the set wind speed in the process of the current indoor humidity difference continuing to decrease from the humidity difference or the humidity difference interval; wherein the second intermediate speed may be greater than or equal to the standard speed value of the set wind speed of the indoor fan.

[0069] Based on the second speed control rule, the speed of the indoor fan can be increased or decreased according to the actual working conditions based on the standard speed value of the set wind speed, and the speed of the indoor fan is controlled to be lower than the standard speed value of the previous wind speed adjacent to the set wind speed when increasing the speed, and higher than the standard speed value of the next wind speed adjacent to the set wind speed when decreasing the speed, the standard speed value of the previous wind speed is greater than the standard speed value of the set wind speed, and the standard speed value of the next wind speed is less than the standard speed value of the set wind speed; for example, when the set wind speed is the medium wind speed, the next wind speed is the second lowest wind speed, and the previous wind speed is the second highest wind speed.

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

[0072] In other words, the multiple internal fan speed values ​​corresponding to the third internal tube temperature interval are all within the third speed range, and the minimum value of the multiple internal fan speed values ​​is greater than or equal to the standard speed value of the set wind speed of the indoor fan.

[0073] At the same time, when the speed of the indoor fan is taken within the third speed range, the speed of the indoor fan gradually increases to a third intermediate speed in the process of the current indoor humidity difference decreasing to a certain humidity difference or a certain humidity difference interval, and gradually decreases from the third intermediate speed in the process of the current indoor humidity difference continuing to decrease from the humidity difference or the humidity difference interval; wherein the third intermediate speed may be greater than the standard speed value of the set wind speed of the indoor fan.

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

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

[0076] S3221: In response to determining that the current indoor humidity difference is in the first humidity difference interval, determine that the rotation speed of the indoor fan is positively correlated with the rate of change of the indoor humidity, and the rotation speed of the indoor fan is less than or equal to a standard rotation speed value of the set windshield of the indoor fan.

[0077] Here, a plurality of humidity difference intervals which are continuously distributed from large to small can be pre-set in the control system of the air conditioner 1, for example, a first humidity difference interval which is greater than or equal to a first humidity difference threshold, a second humidity difference interval which is less than the first humidity difference threshold and greater than or equal to a second humidity difference threshold, a third humidity difference interval which is less than the second humidity difference threshold and greater than or equal to a third humidity difference threshold, and at least three humidity difference intervals. The specific values ​​of the humidity difference thresholds such as the first humidity difference threshold, the second humidity difference threshold, and the third humidity difference threshold can be determined according to actual needs, and the embodiment of the present application does not limit this; for example, the first humidity difference threshold can be 15% to 20%, for example, 15%, 16%, 17%, 18%, 19% or 20%; for example, the second humidity difference threshold can be 0 to 2%, for example, 0, 1% or 2%; for example, the third humidity difference threshold can be -8% to -5%, for example, -8%, -7%, -6% or -5%.

[0078] In the first humidity difference interval, the second speed control rule may also include: the speed of the indoor fan is positively correlated with the indoor humidity change rate, and the speed of the indoor fan is less than or equal to the standard speed value of the set windshield of the indoor fan. In other words, the speed of the indoor fan is controlled to increase with the increase of the indoor humidity change rate and decrease with the decrease of the indoor humidity change rate, and the speed of the indoor fan is controlled to decelerate on the basis of the standard speed value of the set windshield, and the speed of the indoor fan is controlled to be higher than the standard speed value of the next windshield adjacent to the set windshield when the speed is reduced, and the standard speed value of the next windshield is less than the standard speed value of the set windshield; for example, when the set windshield is set to the middle windshield, the next windshield is the second lowest windshield.

[0079] S3222: In response to determining that the current indoor humidity difference is in the second humidity difference interval, determine that the rotation speed of the indoor fan is negatively correlated with the rate of change of the indoor humidity, and the rotation speed of the indoor fan is greater than the standard rotation speed value of the set windshield of the indoor fan.

[0080] In the second humidity difference interval, the second speed control rule may also include: the speed of the indoor fan is negatively correlated with the indoor humidity change rate, and the speed of the indoor fan is greater than the standard speed value of the set windshield of the indoor fan. In other words, the speed of the indoor fan is controlled to decrease as the indoor humidity change rate increases, and to increase as the indoor humidity change rate decreases, and the speed of the indoor fan is controlled to increase speed based on the standard speed value of the set windshield, and the speed of the indoor fan is controlled to be lower than the standard speed value of the previous windshield adjacent to the set windshield when the speed is increased, and the standard speed value of the previous windshield is greater than the standard speed value of the set windshield; for example, when the set windshield is set to the middle windshield, the previous windshield is the second highest windshield.

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

[0082] In the third humidity difference interval, the second speed control rule may also include: the speed of the indoor fan is negatively correlated with the indoor humidity change rate, and the speed of the indoor fan is greater than or equal to the standard speed value of the set windshield of the indoor fan. In other words, the speed of the indoor fan is controlled to decrease as the indoor humidity change rate increases, and to increase as the indoor humidity change rate decreases, and the speed of the indoor fan is controlled to remain unchanged or increase speed based on the standard speed value of the set windshield, and the speed of the indoor fan is controlled to be lower than the standard speed value of the previous windshield adjacent to the set windshield when the speed is increased, and the standard speed value of the previous windshield is greater than the standard speed value of the set windshield; for example, when the set windshield is set to the middle windshield, the previous windshield is the second highest windshield.

[0083] By setting S3221~S3223, the current humidification demand can be accurately predicted according to the current indoor humidity difference and the indoor humidity change rate within the second inner tube temperature range, and 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, take into account thermal comfort and humidity comfort, and improve the user's comfort.

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

[0085] S3231: In response to determining that the current indoor humidity difference is in the first humidity difference interval, determining that the rotation speed of the indoor fan remains unchanged, and the rotation speed of the indoor fan is greater than a standard rotation speed value of a set windshield of the indoor fan.

[0086] Here, a plurality of humidity difference intervals continuously distributed from small to large may be pre-set in the control system of the air conditioner 1, for example, at least three humidity difference intervals may be included, including the first humidity difference interval, the second humidity difference interval, the third humidity difference interval, and the like.

[0087] In the first humidity difference interval, the third speed control rule may also include: the speed of the indoor fan remains unchanged, and the speed of the indoor fan is greater than the standard speed value of the set windshield of the indoor fan. In other words, the speed of the indoor fan is controlled to increase on the basis of the standard speed value of the set windshield, and to maintain a uniform speed at the increased speed. Among them, the increased speed is lower than the standard speed value of the previous windshield adjacent to the set windshield, and the standard speed value of the previous windshield is greater than the standard speed value of the set windshield; for example, when the set windshield is set to the middle windshield, the previous windshield is the second highest windshield.

[0088] S3232: In response to determining that the current indoor humidity difference is in the second humidity difference interval, determine that the rotation speed of the indoor fan is negatively correlated with the rate of change of the indoor humidity, and the rotation speed of the indoor fan is greater than or equal to a standard rotation speed value of the set windshield of the indoor fan.

[0089] In the second humidity difference interval, the third speed control rule may also include: the speed of the indoor fan is negatively correlated with the indoor humidity change rate, and the speed of the indoor fan is greater than or equal to the standard speed value of the set windshield of the indoor fan. In other words, the speed of the indoor fan is controlled to decrease as the indoor humidity change rate increases, and to increase as the indoor humidity change rate decreases, and the speed of the indoor fan is controlled to remain unchanged or increase speed based on the standard speed value of the set windshield, and the speed of the indoor fan is controlled to be lower than the standard speed value of the previous windshield adjacent to the set windshield when the speed is increased, and the standard speed value of the previous windshield is greater than the standard speed value of the set windshield; for example, when the set windshield is set to the middle windshield, the previous windshield is the second highest windshield.

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

[0091] In the third humidity difference interval, the third speed control rule may also include: the speed of the indoor fan is negatively correlated with the indoor humidity change rate, and the speed of the indoor fan is greater than the standard speed value of the set windshield of the indoor fan. In other words, the speed of the indoor fan is controlled to decrease as the indoor humidity change rate increases, and to increase as the indoor humidity change rate decreases, and the speed of the indoor fan is controlled to increase speed based on the standard speed value of the set windshield, and the speed of the indoor fan is controlled to be lower than the standard speed value of the previous windshield adjacent to the set windshield when the speed is increased, and the standard speed value of the previous windshield is greater than the standard speed value of the set windshield; for example, when the set windshield is set to the middle windshield, the previous windshield is the second highest windshield.

[0092] By setting S3231~S3233, the current humidification demand can be accurately predicted according to the current indoor humidity difference and the indoor humidity change rate within the third inner tube temperature range, and 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, take into account both thermal comfort and humidity comfort, and improve the user's comfort.

[0093] In some embodiments, the humidification module may include a water replenishment 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 replenishment container, the humidification container, and the humidification head are connected in sequence by water channels, the first water pump and the first water level sensor are respectively arranged in the water replenishment container, and the first water pump is used to pump the water in the water replenishment container into the humidification container to replenish the humidification container; the second water pump and the second water level sensor are respectively arranged in the humidification container, and the second water pump is used to pump the water in the humidification container to the humidification head. The type of humidification head can be determined according to actual needs, and a microporous humidification nozzle, an ultrasonic atomizer, etc. can be used, which is not limited in the embodiments of the present application. Figure 7 As shown, the humidification control method may include S41 to S43.

[0094] S41: Acquire the water level measured by the first water level sensor and the water level measured by the second water level sensor.

[0095] S42: Controlling the operating state of the first water pump according to the water level measured by the first water level sensor.

[0096] Here, the maximum water replenishment level value, the warning water replenishment level value and the anti-dry pumping level value can be preset. The maximum water replenishment level value is the maximum water level value of the water replenishment container. When the maximum water replenishment level value is exceeded, the water replenishment of the water replenishment container is stopped; the warning water replenishment level value is a critical water level value for reminding the user to manually replenish the water replenishment container, or controlling the water replenishment device to automatically replenish the water replenishment container. When the value is lower than the warning water replenishment level value, the user is reminded to manually replenish the water replenishment container, or controlling the water replenishment device to automatically replenish the water replenishment container; the anti-dry pumping level value is a critical water level value for the water replenishment container to supply water to the humidification container. When the value is lower than the anti-dry pumping level value, the first water pump stops working, and the water replenishment container does 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 value, the first water pump can be controlled to stop working, and the user can be reminded to manually replenish water to the water replenishment container, or the water replenishment device can be controlled to automatically replenish water to the water replenishment container; when the water level measured by the first water level sensor is lower than the warning water replenishment water level value, the user can be reminded to manually replenish water to the water replenishment container, or the water replenishment device can be controlled to automatically replenish water to the water replenishment container, and the first water pump can continue to pump the water in the water replenishment container into the humidification container; when the water level measured by the first water level sensor reaches the maximum water replenishment water level value, the user can be reminded to stop replenishing water to the water replenishment container, or the water replenishment device can be controlled to stop automatically replenishing water to the water replenishment container.

[0098] S43: Controlling the operating state of the second water pump according to the water level measured by the second water level sensor.

[0099] Here, the maximum humidification water level value, the warning humidification water level value and the water shortage shutdown water level value can be preset. The maximum humidification water level value is the maximum water level value of the humidification container. When the maximum humidification water level value is exceeded, the first water pump is controlled to stop replenishing water to the humidification container; the warning humidification water level value is a critical water level value for reminding the user to manually replenish water to the humidification container, or controlling the first water pump to automatically replenish water to the humidification container. When it is lower than the warning humidification water level value, the user is reminded to manually replenish water to the humidification container, or the first water pump is controlled to automatically replenish water to the humidification container; the water shortage shutdown water level value is the critical water level value for the humidification container to supply water to the humidification head. When it is lower than the water shortage shutdown water level value, the second water pump stops working, and the humidification container does not supply water to the humidification head.

[0100] In this way, when the water level measured by the second water level sensor is lower than the water shortage shutdown water level value, 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 is lower than the warning humidification water level value, 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, and the second water pump can continue to pump the water in the humidification container into the humidification head; when the second water pump is a variable frequency pump, the second water pump can be controlled to reduce the frequency to the lower limit to extend the time for the water volume in the humidification container to decrease. When the water level measured by the second water level sensor reaches the maximum humidification water level value, 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 the independent humidification mode, controlling the humidification rate of the humidification module according to the current indoor humidity difference and the indoor humidity change rate.

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