These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0067] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0068] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein, for example.

[0069] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0070] In order to adjust the indoor ambient temperature to the appropriate temperature range as quickly as possible through the air conditioner, it runs at a higher operating frequency and a higher external fan speed when it is just turned on. However, if this operating frequency and external fan speed are maintained all the time, the ambient temperature will be too high or too low, affecting the user experience and increasing energy consumption.

[0071] The existing technology is that users manually adjust the operating frequency and the speed of the external fan according to their own feelings. However, the manual control method cannot accurately control the operating frequency and speed of the external fan of the air conditioner, which reduces the user experience and has low applicability.

[0072] The present application provides an air conditioning control optimization method. When the air conditioning startup frequency rises to the initial frequency, the air conditioning frequency is controlled to be reduced according to the internal environment temperature and the internal unit outlet temperature. At the same time, the minimum speed of the external fan is determined according to the throttle valve opening. Whether to stop the frequency reduction is determined according to the external fan speed and the minimum speed of the external fan during the frequency reduction process. Through the above method, after the air conditioner is turned on and operated for a period of time, the operating frequency is automatically reduced while ensuring the speed of the external fan and not affecting the user experience, thereby reducing the energy consumption of the air conditioner.

[0073] Next, the technical solution shown in the present application is described in detail through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other, and the same or similar contents will not be described repeatedly in different embodiments.

[0074] Figure 1 A schematic diagram of a process of an air conditioning control optimization method provided in an embodiment of the present application Figure 1 .like Figure 1 As shown, the method includes:

[0075] S101. When the air conditioner is turned on and the operating frequency reaches an initial frequency, an air outlet temperature and an internal ambient temperature of an indoor unit of the air conditioner are obtained after a first preset time, and a frequency reduction rate is obtained according to the air outlet temperature and the internal ambient temperature.

[0076] In this step, the initial frequency is determined according to the external environment temperature of the air conditioner outdoor unit.

[0077] When the air conditioner is just turned on, in order to adjust the inner ring temperature to the appropriate temperature range as quickly as possible, the air conditioner will start running at a higher initial frequency. However, when the inner ring temperature is close to or has reached the appropriate temperature range, if the air conditioner is still running at the initial frequency, the inner ring temperature will be too high or too low, affecting the user experience. Therefore, after the air conditioner runs at the initial frequency for the first preset time, the air conditioner is controlled to run at a lower frequency. The first preset time can be 10-20 minutes, or it can be determined according to the actual environment.

[0078] Furthermore, in order to ensure that reducing the operating frequency of the air conditioner does not affect the user's experience, that is, to make the internal environment temperature still change towards the appropriate temperature range, it is necessary to determine the frequency reduction rate according to the difference between the outlet temperature and the internal environment temperature. The specific process is:

[0079] Obtaining a temperature difference between the air outlet temperature and the internal environment temperature;

[0080] The frequency reduction rate is acquired according to the absolute value of the temperature difference, wherein the frequency reduction rate is inversely proportional to the absolute value of the temperature difference.

[0081] S102: Acquire the current opening of the throttle valve, and acquire a rotation speed change threshold value according to the current opening and the opening threshold value.

[0082] In this step, the speed change threshold is the maximum speed at which the air conditioner outdoor fan speed can be increased by adjusting the throttle valve opening.

[0083] The speed of the air conditioner's outdoor fan is affected by the throttle valve opening and the air conditioner's operating frequency, so when the air conditioner is running at a reduced frequency, the speed of the outdoor fan will also decrease. In order not to affect the air supply capacity of the outdoor fan speed, the air conditioner's operating frequency is reduced when necessary, and the outdoor fan speed can be restored to the target speed. Therefore, this embodiment restores the air conditioner's outdoor fan speed to the initial target speed by adjusting the throttle valve opening.

[0084] Specifically, the opening difference between the opening threshold and the current opening is obtained, and the speed change threshold is obtained according to the opening difference and the fan speed change value outside the unit opening. This embodiment does not limit how to obtain the fan speed change value outside the unit opening of the air conditioner throttle valve.

[0085] S103, controlling the air conditioner to reduce the operating frequency according to the frequency reduction rate, and continuously obtaining the current external fan speed, and determining whether to control the air conditioner to stop frequency reduction according to the current external fan speed and the speed change threshold.

[0086] In this step, after obtaining the frequency reduction rate and the speed change threshold, the air conditioner is controlled to reduce the operating frequency according to the frequency reduction rate, and the current external fan speed is continuously obtained. When the current external fan speed is the difference between the target speed and the speed change threshold, the air conditioner is controlled to stop reducing the frequency.

[0087] Furthermore, after the air conditioner is controlled to stop reducing the frequency, in order not to affect the air supply capacity of the fan, it is necessary to adjust the opening of the throttle valve to restore the speed of the outdoor fan to the target speed.

[0088] Specifically, the air conditioner is controlled to adjust the opening of the throttle valve to the opening threshold.

[0089] The present application provides an air conditioning control optimization method. When the air conditioning startup frequency rises to the initial frequency, the air conditioning frequency is controlled to be reduced according to the internal environment temperature and the internal unit outlet temperature. At the same time, the minimum speed of the external fan is determined according to the throttle valve opening. Whether to stop the frequency reduction is determined according to the external fan speed and the minimum speed of the external fan during the frequency reduction process. Through the above method, after the air conditioner is turned on and operated for a period of time, the operating frequency is automatically reduced while ensuring the speed of the external fan and not affecting the user experience, thereby reducing the energy consumption of the air conditioner.

[0090] Figure 2 A schematic diagram of a process of an air conditioning control optimization method provided in an embodiment of the present application Figure 2The embodiment of the present application provides a detailed description of how to determine whether to control the air conditioner to stop reducing the frequency according to the external fan speed and the speed change threshold. Figure 2 As shown, the method includes:

[0091] S201. Obtain a target rotation speed and a current operating frequency, wherein the target rotation speed is determined according to a pre-stored noise requirement.

[0092] In this step, the target frequency is the speed to which the external fan speed needs to be restored.

[0093] Furthermore, in order to ensure the cooling or heating effect of the air conditioner, the air conditioner operating frequency is not lower than the frequency threshold. Therefore, in order to prevent the air conditioner operating frequency from dropping too much, it is necessary to observe the relationship between the current operating frequency of the air conditioner and the frequency threshold during the frequency reduction.

[0094] Specifically, the target rotation speed and the current operating frequency of the air conditioner are obtained. This embodiment does not limit how to obtain the target rotation speed and the current operating frequency of the air conditioner.

[0095] S202: If the current operating frequency is greater than the frequency threshold, and the current external fan speed is equal to the difference between the target speed and the speed change threshold, determine to control the air conditioner to stop reducing the frequency.

[0096] In this step, when the speed of the external fan is reduced to the lowest value that can be reduced, and the current operating frequency of the air conditioner is greater than the frequency threshold, the air conditioner can be directly controlled to stop reducing the frequency.

[0097] Specifically, the minimum speed value to which the external fan speed can be reduced is obtained based on the difference between the target speed and the speed change threshold, and the current external fan speed is continuously obtained during the process of reducing the operating frequency of the air conditioner. When the current external fan speed is equal to the minimum speed value, the air conditioner is controlled to stop reducing the frequency.

[0098] For example, the target speed of the air conditioner is 45, and the speed change threshold is 5. The speed of the external fan is reduced to a minimum value of 45-5=40. When the current speed of the external fan is equal to the minimum value 40, the air conditioner is controlled to stop reducing the speed.

[0099] S203: If the current operating frequency is equal to the frequency threshold, determine to control the air conditioner to stop reducing the frequency.

[0100] In this step, when the air conditioner operating frequency is reduced to the frequency threshold, if the air conditioner continues to reduce the operating frequency at the frequency reduction rate, it will affect the cooling or heating effect of the air conditioner. Therefore, when the air conditioner operating frequency is reduced to the frequency threshold, the air conditioner is directly controlled to stop reducing the frequency.

[0101] The present application provides an air conditioning control optimization method, which determines whether to control the air conditioner to stop reducing the frequency according to the magnitude of the current operating frequency and the frequency threshold, and the magnitude of the difference between the current external fan speed and the target speed and the speed change threshold. Through the above method, the operating frequency of the air conditioner is reduced without affecting the air supply capacity of the external fan.

[0102] Figure 3 A schematic diagram of a process of an air conditioning control optimization method provided in an embodiment of the present application Figure 3 The embodiment of the present application provides a detailed description of how to determine whether to control the air conditioner to stop reducing the frequency according to the external fan speed and the speed change threshold. Figure 3 As shown, the method includes:

[0103] S301. After a second preset time, obtain the current inner ring temperature, the current indoor unit air outlet temperature and the current external coil sensor temperature of the air conditioner.

[0104] In this step, the target speed is the maximum allowable external fan speed obtained based on the noise requirement. However, in addition to the noise requirement, the external fan speed will also affect the user experience. Therefore, in order to further improve the user experience, the recommended external fan speed of the air conditioner can be obtained based on the operating parameters of the air conditioner at this time.

[0105] Furthermore, among the air conditioning parameters, the parameters that have the greatest impact on air conditioning adjustment and user experience are: inner ring temperature, indoor unit air outlet temperature and external coil sensor temperature. Therefore, this embodiment obtains the recommended external fan speed based on the inner ring temperature, indoor unit air outlet temperature and external coil sensor temperature.

[0106] Specifically, when the air conditioner adjusts the throttle valve opening to the opening threshold and runs for the second preset time, the current inner ring temperature, the current indoor unit outlet temperature and the current external coil sensor temperature of the air conditioner are obtained. All three temperatures can be obtained through the temperature sensor.

[0107] S302: Obtain the recommended external fan speed corresponding to the current inner ring temperature, the current indoor unit air outlet temperature, and the current external coil sensor temperature according to a preset relationship.

[0108] In this step, the preset relationship is used to indicate the corresponding relationship between the recommended external fan speed and the current inner ring temperature, the current indoor unit air outlet temperature and the current external coil sensor temperature.

[0109] Specifically, the inner ring temperature range to which the current inner ring temperature belongs is obtained; the inner unit outlet temperature range to which the current inner unit outlet temperature belongs is obtained; and the outer coil temperature range to which the current outer coil sensor temperature belongs is obtained. The inner ring temperature range, the inner unit outlet temperature range, and the outer coil temperature range are obtained according to the preset relationship to obtain the corresponding recommended outer fan speed.

[0110] S303, sending a prompt message to the user end, and if receiving the user's feedback within the preset time, controlling the air conditioner to adjust the speed of the external fan to the recommended external fan speed.

[0111] In this step, the prompt information is used to determine whether the user controls the air conditioner to run according to the recommended external fan speed.

[0112] Specifically, after obtaining the recommended external fan speed, a prompt message is generated according to the recommended external fan speed and sent to the user end. If the user's feedback is received within the preset time, the speed of the air conditioner's external fan is adjusted according to the recommended external fan speed. If the user's feedback is not received within the preset time, the air conditioner's external fan is controlled to rotate at the target speed.

[0113] Furthermore, there are multiple ways to adjust the speed of the external fan. Since the air conditioner operating frequency has been reduced before, it is best not to adjust the speed of the external fan by adjusting the air conditioner operating frequency. At this time, the opening of the throttle valve is at the opening threshold. If the speed of the external fan needs to be reduced, the opening of the throttle valve can be reduced. When the speed of the external fan needs to be increased, the speed of the external fan can be increased by increasing the air conditioner operating frequency.

[0114] Therefore, it is necessary to obtain the size relationship between the recommended external fan speed and the target speed, and select the corresponding method to adjust the external fan speed according to the size relationship. The specific operations are as follows:

[0115] If the recommended external fan speed is less than the target speed, the air conditioner is controlled to adjust the throttle valve opening to adjust the speed of the external fan to the recommended external fan speed.

[0116] Specifically, when it is determined that the recommended external fan speed is less than the target speed, the opening adjustment value is obtained according to the difference between the target speed and the recommended external fan speed, and then the throttle valve is controlled to reduce the opening according to the opening adjustment value. The specific operation is:

[0117] Obtaining a difference between the target speed and the recommended external fan speed, and obtaining a ratio of the difference to the speed change threshold;

[0118] Obtaining the product of the difference between the opening threshold and the current opening and the ratio, and obtaining the opening adjustment value according to the product;

[0119] The opening of the air conditioning throttle valve is reduced according to the opening adjustment value.

[0120] For example, the target speed is 35, and the recommended external fan speed is 30. The speed change threshold is 10, the current opening is 60, and the opening threshold is 80. The difference between the target speed and the recommended external fan speed is: 35-30=5, the ratio is the ratio of the difference 5 and the speed change threshold 10, that is: 5 / 10=0.5, and the difference in opening is: the difference between the opening threshold 80 and the current opening 60, that is: 80-60=20. The final calculated opening adjustment value is 0.5*20=10, and the air conditioning throttle valve opening is controlled to decrease by 10.

[0121] Furthermore, if the recommended external fan speed is greater than the target speed, the air conditioner is controlled to increase the operating frequency to adjust the external fan speed to the recommended external fan speed.

[0122] The present application provides an air conditioning control optimization method. After the air conditioner stops reducing the frequency and the external fan speed returns to the target speed for a period of time, the recommended external fan speed is obtained according to the current inner ring temperature, the current internal unit air outlet temperature and the current external coil sensor temperature, and the air conditioner is controlled to adjust the external fan speed to the recommended external fan speed after receiving user feedback. In this way, the user experience can be made more comfortable and the user's willingness to use can be improved.

[0123] Figure 4 This is a schematic diagram of the structure of an air conditioning control optimization control device provided in an embodiment of the present application. Figure 4 As shown, the device includes: a frequency adjustment module 401, a speed adjustment module 402 and a determination module 403, wherein:

[0124] The frequency adjustment module 401 is used for obtaining the air outlet temperature and the internal environment temperature of the air conditioner indoor unit after a first preset time when the air conditioner is turned on and the operating frequency reaches the initial frequency, and obtaining the frequency reduction rate according to the air outlet temperature and the internal environment temperature, wherein the initial frequency is determined according to the external environment temperature of the air conditioner outdoor unit;

[0125] The speed adjustment module 402 is used to obtain the current opening of the throttle valve, and obtain the speed change threshold value according to the current opening and the opening threshold value, wherein the speed change threshold value is the maximum speed at which the speed of the air conditioner outdoor fan can be increased by adjusting the throttle valve opening;

[0126] The determination module 403 is used to control the air conditioner to reduce the operating frequency according to the frequency reduction rate, and continuously obtain the current external fan speed, and determine whether to control the air conditioner to stop frequency reduction according to the current external fan speed and the speed change threshold.

[0127] In a possible implementation manner, the determining module 403 is further configured to:

[0128] Obtaining a target speed and a current operating frequency, wherein the target speed is determined according to a pre-stored noise requirement;

[0132] Obtaining a temperature difference between the air outlet temperature and the internal environment temperature;

[0133] The frequency reduction rate is acquired according to the absolute value of the temperature difference, wherein the frequency reduction rate is inversely proportional to the absolute value of the temperature difference.

[0134] In a possible implementation manner, the frequency adjustment module 401 is further configured to:

[0135] The air conditioner is controlled to adjust the opening of the throttle valve to the opening threshold.

[0136] In a possible implementation manner, the speed adjustment module 402 is further configured to:

[0137] After the second preset time, the current inner ring temperature, the current indoor unit air outlet temperature and the current external coil sensor temperature of the air conditioner are obtained;

[0138] Obtaining the recommended external fan speed corresponding to the current inner ring temperature, the current indoor unit air outlet temperature and the current external coil sensor temperature according to a preset relationship, wherein the preset relationship is used to indicate the corresponding relationship between the recommended external fan speed and the current inner ring temperature, the current indoor unit air outlet temperature and the current external coil sensor temperature;
