[0043] The objectives, features, and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0044] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Currently, when adjusting the fan speed of air conditioning equipment, if an automatic fan control scheme is used, the air conditioning equipment will always operate at a high fan speed because the temperature has not been reached; if a user-set control scheme is used, the ambient temperature in the working space of the air conditioning equipment will not be maintained because the fan speed set by the user is unreasonable.

[0046] Therefore, it can be seen that the existing control schemes for air conditioning equipment are prone to situations where the fan speed is too high or the temperature cannot be maintained when adjusting the fan speed, thus affecting the energy efficiency and comfort of the air conditioning equipment.

[0047] Based on this, the present invention proposes an automatic control method for an air conditioning device according to a first embodiment, please refer to... Figure 1 The automatic control method for the air conditioning equipment includes:

[0048] Step S10: Periodically acquire the change in the temperature difference between the ambient temperature and the target temperature within the working space of the air conditioning equipment;

[0049] In this embodiment, the air conditioning equipment can be the main body executing the automatic control method of the air conditioning equipment. The air conditioning equipment refers to the equipment that processes the air in the work space to maintain the set temperature and humidity in the work space and control the dust and harmful gas content in the work space. The air conditioning equipment can be an air conditioner, an air dehumidifier, an air humidifier, etc., and this embodiment does not make specific limitations on it.

[0050] It should be noted that the target temperature refers to the desired ambient temperature set by the air conditioning equipment. The change in temperature difference is the difference between the ambient temperature and the target temperature obtained in the current cycle and the difference between the ambient temperature and the target temperature obtained in the previous cycle. The temperature difference between the ambient temperature and the target temperature is the absolute value of the difference between the two temperatures. In this embodiment, the change in temperature difference is a parameter carrying a positive or negative sign. For example, if the temperature difference between the ambient temperature and the target temperature obtained in the current cycle is 3, and the temperature difference between the ambient temperature and the target temperature obtained in the previous cycle is 5, then the change in temperature difference is -2.

[0051] When periodically acquiring the change in temperature difference between the ambient temperature and the target temperature within the working space of the air conditioning equipment, the time interval between each acquisition can be a default time interval, or the time interval can be adjusted adaptively according to actual needs. This embodiment does not impose specific limitations on this.

[0052] Step S20: Determine the target fan speed of the air conditioning equipment at the current moment based on the change in temperature difference;

[0053] It should be noted that the target fan speed is the speed that the internal fan of the air conditioning equipment needs to be adjusted to at the current moment.

[0054] Air conditioning equipment may limit the minimum fan speed. Therefore, in the process of determining the target fan speed of the air conditioning equipment at the current moment based on the change in temperature difference, if the initially determined target fan speed is less than the preset minimum fan speed, then the minimum fan speed needs to be used as the final target fan speed.

[0055] In a first feasible implementation, step S20 may specifically include:

[0056] Step S201: Based on the preset relationship between the change in temperature difference and the wind speed adjustment, determine the wind speed adjustment corresponding to the change in temperature difference, and obtain the current fan speed of the air conditioning equipment.

[0057] It should be noted that a single temperature difference change can correspond to a single wind speed adjustment, or multiple temperature differences can correspond to a single wind speed adjustment; this embodiment does not impose a specific limitation on this. The wind speed adjustment amount refers to the magnitude by which the fan speed is increased or decreased.

[0058] Additionally, it should be noted that the wind speed adjustment amount in this embodiment can be a parameter with a positive or negative sign, or a parameter without a positive or negative sign. This embodiment does not impose any specific limitations on this. If the wind speed adjustment amount is a parameter with a positive or negative sign, the value range of the wind speed adjustment amount is [-100, 100]; if the wind speed adjustment amount is a parameter without a positive or negative sign, the value range of the wind speed adjustment amount is [0, 100].

[0059] For example, if the wind speed adjustment is a parameter with a positive or negative sign, the change in temperature difference is positively correlated with the wind speed adjustment; if the wind speed adjustment is a parameter without a positive or negative sign, the change in temperature difference is positively correlated with the wind speed adjustment when the change in temperature difference is greater than zero, and negatively correlated when the change in temperature difference is less than zero.

[0060] A wind speed adjustment relationship table can be set up to record the changes in temperature differences and the corresponding wind speed adjustments. Therefore, step S201 can specifically include: finding the wind speed adjustment corresponding to the changes in temperature differences in the preset wind speed adjustment relationship table.

[0061] Step S202: Calculate the target fan speed of the air conditioning equipment at the current moment based on the fan speed at the current moment and the fan speed adjustment amount corresponding to the change in temperature difference.

[0062] As an example, if the wind speed adjustment amount is a parameter carrying a positive or negative sign, then step S202 may specifically include: calculating the sum of the wind speed adjustment amounts corresponding to the change in the fan wind speed and the temperature difference at the current moment, to obtain the target fan wind speed of the air conditioning equipment at the current moment.

[0063] As another example, if the wind speed adjustment is a parameter without a positive or negative sign, step S202 may specifically include: when the change in temperature difference is greater than zero, calculating the sum of the current fan speed and the wind speed adjustment corresponding to the change in temperature difference to obtain the target fan speed of the air conditioning equipment at the current moment; when the change in temperature difference is less than zero, calculating the difference between the current fan speed and the wind speed adjustment corresponding to the change in temperature difference to obtain the target fan speed of the air conditioning equipment at the current moment.

[0064] This embodiment determines the corresponding wind speed adjustment amount based on a preset relationship between the change in temperature difference and the wind speed adjustment amount. This determined wind speed adjustment amount is then used to adjust the current fan speed of the air conditioning equipment, resulting in the target fan speed for that moment. Consequently, by operating the air conditioning equipment according to this target fan speed, the fan speed can adaptively adjust to the changing trend of the temperature difference between the ambient and target temperatures. This avoids situations where the air conditioning equipment operates at excessively high wind speeds and fails to maintain the temperature, thus improving the energy efficiency and comfort of the air conditioning system.

[0065] In a second feasible implementation, step S20 may specifically include:

[0066] Step S203: Based on the preset relationship between the change in temperature difference and the fan speed, determine the fan speed corresponding to the change in temperature difference, and use it as the target fan speed of the air conditioning equipment at the current moment.

[0067] It should be noted that a single temperature difference change can correspond to a single fan speed, or multiple temperature differences can correspond to a single fan speed; this embodiment does not impose a specific limitation on this. Generally, the larger the temperature difference change, the higher the corresponding fan speed.

[0068] A wind speed relationship table can be set up to record the changes in temperature differences and the corresponding fan speeds. Therefore, step S203 can specifically include: finding the fan speed corresponding to the changes in temperature differences in the preset wind speed relationship table.

[0069] This embodiment determines the fan speed corresponding to the pre-defined relationship between the change in temperature difference and the fan speed, and directly uses this fan speed as the target fan speed for the air conditioning equipment at the current moment. Therefore, by operating the air conditioning equipment according to this target fan speed, the fan speed can be adaptively adjusted to follow the changing trend of the temperature difference between the ambient temperature and the target temperature. This avoids situations where the air conditioning equipment operates at excessively high fan speeds and cannot maintain the temperature, thereby improving the energy efficiency and comfort of the air conditioning equipment.

[0070] In a third feasible implementation, step S20 may specifically include:

[0071] Step S204: Obtain the current fan speed of the air conditioning device;

[0072] Step S205: When the change in temperature difference is greater than zero, the target fan speed of the air conditioning equipment at the current moment is calculated based on the fan speed at the current moment and the preset increase in fan speed.

[0073] It is understandable that when the change in temperature difference is greater than zero, it means that the temperature difference between the ambient temperature and the target temperature is gradually increasing. If the current fan speed of the air conditioning equipment is too low, then in order to reduce the temperature difference between the ambient temperature and the target temperature and to prevent the temperature difference from continuing to increase, it is necessary to increase the fan speed of the air conditioning equipment to ensure the stability of the ambient temperature and to ensure that the ambient temperature can reach the target temperature.

[0074] As an example, step S205 may specifically include: calculating the sum of the current fan speed and the preset increase in fan speed to obtain the target fan speed of the air conditioning equipment at the current moment.

[0075] Step S206: When the change in temperature difference is less than zero, the target fan speed of the air conditioning equipment at the current moment is calculated based on the fan speed at the current moment and the preset reduction in fan speed.

[0076] It should be noted that the increase in wind speed and the decrease in wind speed may be equal or unequal, and this embodiment does not impose any specific limitation on this.

[0077] It is understandable that when the change in temperature difference is less than zero, it means that the temperature difference between the ambient temperature and the target temperature is gradually decreasing, and the current fan speed of the air conditioning equipment is too high. At this time, the fan speed of the air conditioning equipment can be appropriately reduced to avoid unnecessary energy consumption caused by excessive fan speed, so as to improve the energy efficiency of the air conditioning equipment.

[0078] As an example, step S206 may specifically include: calculating the difference between the current fan speed and the preset reduction in fan speed to obtain the target fan speed of the air conditioning equipment at the current moment.

[0079] In this embodiment, when the temperature difference change is greater than zero, the fan speed of the air conditioning equipment is increased by a preset increase in fan speed to avoid the air conditioning equipment being unable to maintain the temperature, thereby improving the comfort of using the air conditioning equipment; when the temperature difference change is less than zero, the fan speed of the air conditioning equipment is decreased by a preset decrease in fan speed to avoid the air conditioning equipment having an excessively high fan speed, thereby improving the energy efficiency and comfort of using the air conditioning equipment.

[0080] The above are only three feasible implementations of step S20 provided in this embodiment. This embodiment does not specifically limit the specific implementation of step S20. For example, in other implementations of step S20, the rate of change of temperature difference can be determined first by the amount of change of temperature difference, and then the target fan speed of the air conditioning equipment at the current moment can be determined by the rate of change of temperature difference.

[0081] Step S30: Control the air conditioning equipment to operate according to the target fan speed.

[0082] This embodiment provides an automatic control method for an air conditioning device. First, it periodically acquires the change in the temperature difference between the ambient temperature and the target temperature within the working space of the air conditioning device. Then, based on this temperature difference change, it determines the target fan speed of the air conditioning device at the current moment. Next, it controls the air conditioning device to operate at the target fan speed. Since the change in the temperature difference between the ambient and target temperatures reflects the trend of this temperature difference, and this trend reflects whether the fan speed of the air conditioning device is reasonable at the current moment, this embodiment uses the trend of the temperature difference between the ambient and target temperatures as a basis to achieve adaptive adjustment of the fan speed of the air conditioning device. This allows the fan speed to be adjusted reasonably according to the trend of the temperature difference between the ambient and target temperatures, thereby avoiding situations where the air conditioning device has excessively high fan speeds or cannot maintain the temperature, thus improving the energy efficiency and comfort of the air conditioning device.

[0083] In one feasible implementation, step S20 may include:

[0084] Step S21: Calculate the rate of change of temperature difference based on the amount of change of temperature difference and the acquisition period of the amount of change of temperature difference;

[0085] It should be noted that the rate of change of temperature difference refers to the rate of change of temperature difference per unit time.

[0086] As an example, step S21 may specifically include: calculating the ratio of the change in temperature difference to the acquisition period of the change in temperature difference, and obtaining the rate of change in temperature difference.

[0087] Step S22: Determine the target fan speed of the air conditioning equipment at the current moment based on the temperature difference change rate.

[0088] As an example, step S22 may specifically include:

[0089] Step S221: Based on the preset relationship between the temperature difference change rate and the wind speed adjustment amount, determine the wind speed adjustment amount corresponding to the temperature difference change rate, and obtain the current fan speed of the air conditioning equipment.

[0090] It should be noted that there can be one temperature difference change rate corresponding to one wind speed adjustment, or multiple temperature difference change rates corresponding to one wind speed adjustment; this embodiment does not impose a specific limitation on this. In this embodiment, the temperature difference change rate is a parameter carrying a positive or negative sign.

[0091] For example, if the wind speed adjustment is a parameter with a positive or negative sign, the rate of change of temperature difference is positively correlated with the wind speed adjustment; if the wind speed adjustment is a parameter without a positive or negative sign, the rate of change of temperature difference is positively correlated with the wind speed adjustment when the change of temperature difference is greater than zero, and negatively correlated when the change of temperature difference is less than zero.

[0092] A wind speed adjustment relationship table can be set up to record the rate of change of each temperature difference and the wind speed adjustment corresponding to each rate of change of temperature difference. Therefore, step S221 may specifically include: finding the wind speed adjustment corresponding to the rate of change of temperature difference in the preset wind speed adjustment relationship table.

[0093] Step S222: Calculate the target fan speed of the air conditioning equipment at the current moment based on the fan speed at the current moment and the speed adjustment amount corresponding to the temperature difference change rate.

[0094] As an example, if the wind speed adjustment amount is a parameter carrying a positive or negative sign, then step S222 may specifically include: calculating the sum of the wind speed adjustment amount corresponding to the current fan wind speed and the rate of change of temperature difference, to obtain the target fan wind speed of the air conditioning equipment at the current moment.

[0095] As another example, if the wind speed adjustment is a parameter without a positive or negative sign, then step S222 may specifically include: when the change in temperature difference is greater than zero, calculating the sum of the current fan speed and the wind speed adjustment corresponding to the rate of change of temperature difference to obtain the target fan speed of the air conditioning equipment at the current moment; when the change in temperature difference is less than zero, calculating the difference between the current fan speed and the wind speed adjustment corresponding to the rate of change of temperature difference to obtain the target fan speed of the air conditioning equipment at the current moment.

[0096] This example determines the corresponding wind speed adjustment amount based on the preset relationship between the rate of change of temperature difference and the wind speed adjustment amount. This determined wind speed adjustment amount is then used to adjust the current fan speed of the air conditioning equipment, resulting in the target fan speed for that moment. Subsequently, by operating the air conditioning equipment according to this target fan speed, the fan speed can be adaptively adjusted to follow the changing trend of the temperature difference between the ambient and target temperatures. This avoids situations where the air conditioning equipment operates at excessively high wind speeds and fails to maintain the temperature, thus improving the energy efficiency and comfort of the air conditioning system.

[0097] As another example, step S22 may specifically include:

[0098] Step S223: Based on the preset relationship between the temperature difference change rate and the fan speed, determine the fan speed corresponding to the temperature difference change rate as the target fan speed of the air conditioning equipment at the current moment.

[0099] It should be noted that one temperature difference change rate can correspond to one fan speed, or multiple temperature difference change rates can correspond to one fan speed; this embodiment does not impose a specific limitation on this. Generally, the larger the temperature difference change rate, the higher the corresponding fan speed.

[0100] A wind speed relationship table can be set up to record the rate of change of each temperature difference and the fan speed that corresponds to each rate of change of temperature difference. Therefore, step S223 may specifically include: finding the fan speed corresponding to the rate of change of temperature difference in the preset wind speed relationship table.

[0101] This example determines the fan speed corresponding to the pre-defined relationship between the rate of change of temperature difference and the fan speed. This fan speed, corresponding to the change in temperature difference, is then directly used as the target fan speed for the air conditioning unit at the current moment. Therefore, by operating the air conditioning unit according to this target fan speed, the fan speed can be adaptively adjusted to follow the changing trend of the temperature difference between the ambient and target temperatures. This avoids situations where the air conditioning unit operates at excessively high fan speeds and fails to maintain the temperature, thus improving the energy efficiency and comfort of the air conditioning system.

[0102] Based on the first embodiment of the present invention, in the second embodiment of the present invention, the same or similar content as in the first embodiment can be referred to the above description, and will not be repeated hereafter. Furthermore, the automatic control method for the air conditioning equipment further includes:

[0103] Step S01: When the AI-managed operation time of the air conditioning equipment reaches the preset time, the change in the temperature difference between the ambient temperature and the target temperature in the working space of the air conditioning equipment is periodically acquired until the AI-managed operation is turned off.

[0104] Currently, automatic fan control schemes can adjust the fan speed of air conditioning equipment based on the temperature difference between the ambient temperature and the target temperature within the air conditioning unit's working space. Specifically, the fan speed decreases as the temperature difference decreases. While this method prevents excessively high fan speeds, it can affect the rate at which the air conditioning unit reaches the desired temperature. Furthermore, if the working space is large, it may even fail to reach the required temperature, thus impacting the comfort of using the air conditioning equipment.

[0105] It should be noted that AI (Artificial Intelligence) management is a function of automated control. The preset duration can be a default value or a value that can be flexibly changed according to the actual situation; this embodiment does not impose a specific limitation on it.

[0106] Understandably, after an air conditioning unit starts using its AI-managed function, it typically needs to run for a certain period to reach the target temperature. During this time, the air conditioning unit usually needs to maintain a high fan speed to ensure that the ambient temperature within the air conditioning unit's working space reaches the target temperature quickly. Therefore, this embodiment limits the subsequent fan speed adjustment to follow the temperature difference between the ambient and target temperatures only after the AI-managed operation has reached a preset duration. This improves the energy efficiency and comfort of the air conditioning unit without affecting its temperature-reaching rate.

[0107] Furthermore, as the subsequent fan speed adaptively adjusts according to the changing trend of the temperature difference between the ambient temperature and the target temperature, the fan speed of the air conditioning equipment can be increased in a timely manner when the temperature difference shows a gradually decreasing trend, so as to avoid the air conditioning equipment failing to reach the desired temperature, thereby further improving the comfort of using the air conditioning equipment.

[0108] For example, to facilitate understanding of the implementation flow of the automatic control method for the air conditioning equipment combined with the first embodiment described above, please refer to... Figure 2 , specifically:

[0109] When the AI-managed operation time of the air conditioning equipment reaches the preset duration, the temperature difference ΔTn between the ambient temperature and the target temperature in the air conditioning equipment's working space for the current period is periodically obtained. The difference between this temperature difference ΔTn and the temperature difference ΔTn-1 between the ambient temperature and the target temperature in the air conditioning equipment's working space for the previous period is calculated to obtain the change in temperature difference ΔT. If the change in temperature difference ΔT is greater than zero, it indicates that the temperature difference between the ambient temperature and the target temperature is gradually increasing, so the fan speed of the air conditioning equipment needs to be increased, and the air conditioning equipment is controlled to operate at the increased fan speed. If the change in temperature difference ΔT is less than zero, it indicates that the temperature difference between the ambient temperature and the target temperature is gradually decreasing, so the fan speed of the air conditioning equipment needs to be decreased, and the air conditioning equipment is controlled to operate at the decreased fan speed. If the change in temperature difference ΔT is equal to zero, the fan speed of the air conditioning equipment does not need to be adjusted, and the air conditioning equipment continues to operate at the current fan speed.

[0110] To better understand the implementation process of the automatic control method for the air conditioning equipment in this example, taking a preset duration of 50 minutes and a data acquisition cycle of 10 minutes as an example, please refer to... Figure 3 During the first 50 minutes of AI-managed operation of the air conditioning equipment, the air conditioning equipment is maintained at a relatively high fan speed. After the air conditioning equipment has been running under AI management for 50 minutes, the fan speed begins to adaptively adjust according to changes in temperature difference. Specifically:

[0111] At the 50th minute, the target temperature was 25℃, the ambient temperature was 24℃, and the temperature difference was 1℃.

[0112] At the 60th minute, the target temperature is 25℃, the ambient temperature is 24.5℃, and the temperature difference is 0.5℃. Compared with the 50th minute, the temperature difference has decreased by 0.5℃, that is, the change in temperature difference is -0.5℃. Therefore, the fan speed is reduced to 40.

[0113] At the 70th minute, the target temperature is 25℃, the ambient temperature is 24℃, and the temperature difference is 1℃. Compared with the 60th minute, the temperature difference increases by 0.5℃, that is, the change in temperature difference is +0.5℃. Therefore, the fan speed is increased to 60.

[0114] At the 80th minute, the target temperature is 25℃, the ambient temperature is 24.5℃, and the temperature difference is 0.5℃. Compared with the 70th minute, the temperature difference has decreased by 0.5℃, that is, the change in temperature difference is -0.5℃. Therefore, the fan speed is reduced to 40.

[0115] It should be noted that this example is only for the purpose of assisting in understanding the present invention and does not constitute a limitation on the automatic control method of the air conditioning equipment of the present invention. Any simple modifications based on this technical concept are within the protection scope of the present invention.

[0116] This invention also provides an automatic control device for an air conditioning equipment; please refer to... Figure 4 The automatic control device of the air conditioning equipment includes:

[0117] The acquisition module 10 is used to periodically acquire the change in the temperature difference between the ambient temperature and the target temperature within the working space of the air conditioning equipment.

[0118] The determining module 20 is used to determine the target fan speed of the air conditioning equipment at the current moment based on the change in the temperature difference;
