Technical Field

[0001] This application belongs to the field of smart home appliance technology, specifically relating to an air conditioning control optimization method, device, air conditioner, and storage medium. Background Technology

[0002] When an air conditioner is first used, in order to quickly lower or raise the indoor temperature, the initial operating frequency and outdoor fan speed are relatively high. Once the indoor temperature reaches a suitable range, if it continues to operate at the initial operating frequency and outdoor fan speed, the indoor temperature will be too high or too low, affecting the user experience and consuming more energy.

[0003] To address the aforementioned issues, existing technologies typically employ the following approach: once the indoor temperature reaches a suitable range, the user manually adjusts the air conditioner's operating frequency to ensure a positive user experience and reduce energy consumption.

[0004] However, the above methods rely on manual adjustment, which cannot accurately control the operating frequency and speed of the air conditioner and the outdoor fan, thus reducing the user experience and having limited applicability. Summary of the Invention

[0029] The opening degree of the air conditioning flow control valve is reduced according to the opening degree adjustment value.

[0030] Secondly, this application also provides an air conditioning control optimization control device, comprising: a frequency adjustment module, a speed adjustment module, and a determination module, wherein:

The preset relationship is used to indicate the correspondence between the recommended outdoor fan speed and the current inner ring temperature, the current indoor unit air outlet temperature and the current outdoor coil sensor temperature.

[0046] A prompt message is sent to the user. If feedback is received from the user within a preset time, the air conditioner is controlled to adjust the speed of the outdoor fan to the recommended outdoor fan speed. The prompt message is used to determine whether the user has controlled the air conditioner to operate at the recommended outdoor fan speed.

[0047] In one possible implementation, the speed adjustment module is further configured to:

[0066] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0067] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

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

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

[0070] To quickly adjust the indoor temperature to a comfortable range using air conditioning, it operates at a higher frequency and higher outdoor fan speed when first turned on. However, maintaining this operating frequency and outdoor fan speed continuously can cause the ambient temperature to become too high or too low, affecting the user experience and increasing energy consumption.

[0071] Current technology requires users to manually adjust the operating frequency and outdoor fan speed based on their own experience. However, this manual adjustment method cannot precisely control the air conditioner's operating frequency and outdoor fan speed, reducing the user experience and limiting its applicability.

[0072] This application provides an air conditioning control optimization method. When the air conditioner's operating frequency rises to its initial frequency, the method controls the air conditioner to reduce its frequency based on the indoor ambient temperature and the indoor unit's air outlet temperature. Simultaneously, it determines the minimum speed of the outdoor fan based on the throttle valve opening. The method then determines whether to stop frequency reduction based on the outdoor fan speed and the minimum outdoor fan speed during the frequency reduction process. Through this method, the air conditioner automatically reduces its operating frequency after running for a period of time, while maintaining the outdoor fan speed and not affecting the user experience, thereby reducing the air conditioner's energy consumption.

[0073] Next, the technical solutions shown in this application will be described in detail through specific embodiments. It should be noted that the following embodiments may exist alone or in combination with each other, and the same or similar content will not be described again in different embodiments.

[0074] Figure 1 A flowchart illustrating an air conditioning control optimization method provided in this application embodiment. Figure 1 .like Figure 1 As shown, the method includes:

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

[0076] In this step, the initial frequency is determined based on the ambient temperature of the outdoor unit of the air conditioner.

[0077] When an air conditioner is first turned on, it starts running at a higher initial frequency to quickly adjust the inner ambient temperature to a suitable range. However, if the air conditioner continues to run at the initial frequency when the inner ambient temperature is close to or has already reached the suitable range, the inner ambient temperature will be too high or too low, affecting the user experience. Therefore, after running at the initial frequency for a first preset time, the air conditioner is controlled to reduce its frequency. The first preset time can be 10-20 minutes, or it can be determined according to the actual environment.

[0078] Furthermore, to ensure that reducing the air conditioner's operating frequency does not affect the user's experience—that is, to maintain the indoor temperature within a suitable range—the frequency reduction rate needs to be determined based on the difference between the air outlet temperature and the indoor temperature. The specific process is as follows:

[0079] The temperature difference between the air outlet temperature and the internal ambient temperature is obtained;

[0080] The frequency reduction rate is obtained based on 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. Obtain the current opening degree of the throttle valve, and obtain the speed change threshold based on the current opening degree and the opening degree threshold.

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

[0083] The speed of the air conditioner's outdoor fan is affected by factors such as the opening of the throttle valve and the air conditioner's operating frequency. Therefore, when the air conditioner operates at a reduced frequency, the outdoor fan speed will also decrease. To avoid affecting the air delivery capacity of the outdoor fan, the air conditioner's operating frequency is reduced when necessary, allowing the outdoor fan speed to return to the target speed. Therefore, this embodiment adjusts the opening of the throttle valve to restore the air conditioner's outdoor fan speed to its initial target speed.

[0084] Specifically, the difference between the opening threshold and the current opening is obtained, and the speed change threshold is obtained based on the opening difference and the change in external fan speed per unit opening. This embodiment does not limit how the change in external fan speed per unit opening of the air conditioning flow control valve is obtained.

[0085] S103. Control the air conditioner to reduce its operating frequency according to the frequency reduction rate, and continuously acquire the current outdoor fan speed. Based on the current outdoor fan speed and the speed change threshold, determine whether to control the air conditioner to stop reducing the frequency.

[0086] In this step, after obtaining the frequency reduction rate and the speed change threshold, the air conditioner is controlled to reduce its operating frequency according to the frequency reduction rate, and the current outdoor fan speed is continuously obtained. When the current outdoor 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 stops reducing its frequency, in order not to affect the air delivery capacity of the fan, it is necessary to adjust the opening of the throttle valve to restore the outdoor fan speed to the target speed.

[0088] Specifically, the opening degree of the air conditioning adjustment throttle valve is controlled to the opening degree threshold.

[0089] This application provides an air conditioning control optimization method. When the air conditioner's operating frequency rises to its initial frequency, the method controls the air conditioner to reduce its frequency based on the indoor ambient temperature and the indoor unit's air outlet temperature. Simultaneously, it determines the minimum speed of the outdoor fan based on the throttle valve opening. The method then determines whether to stop frequency reduction based on the outdoor fan speed and the minimum outdoor fan speed during the frequency reduction process. Through this method, the air conditioner automatically reduces its operating frequency after running for a period of time, while maintaining the outdoor fan speed and not affecting the user experience, thereby reducing the air conditioner's energy consumption.

[0090] Figure 2 A flowchart illustrating an air conditioning control optimization method provided in this application embodiment. Figure 2This application provides a detailed explanation of the steps for determining whether to control the air conditioner to stop reducing its frequency based on the outdoor fan speed and a speed change threshold. For example... Figure 2 As shown, the method includes:

[0091] S201. Obtain the target rotational speed and the current operating frequency, wherein the target rotational speed is determined based on pre-stored noise requirements.

[0092] In this step, the target frequency is the speed at 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's operating frequency should not be lower than the frequency threshold. Therefore, in order to prevent the air conditioner's operating frequency from dropping too much, it is necessary to observe the relationship between the current operating frequency and the frequency threshold during the frequency reduction process.

[0094] Specifically, the target speed and current operating frequency of the air conditioner are obtained. This embodiment does not impose any limitations on the method by which the target speed and current operating frequency of the air conditioner are obtained.

[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, then it is determined to control the air conditioner to stop reducing the frequency.

[0096] In this step, when the outdoor fan speed is reduced to the lowest possible value, 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 at which the outdoor fan speed can be reduced is obtained based on the difference between the target speed and the speed change threshold. The current outdoor fan speed is continuously obtained during the process of the air conditioner reducing its operating frequency. When the current outdoor fan speed is equal to the minimum speed value, the air conditioner is controlled to stop reducing its frequency.

[0098] For example, the target speed of the air conditioner is 45, and the speed change threshold is 5. The outdoor fan speed is reduced to the lowest possible value of 45-5=40. When the current outdoor fan speed equals the minimum value of 40, the air conditioner is controlled to stop reducing its frequency.

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

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

[0101] This application provides an air conditioning control optimization method. Based on the magnitude of the current operating frequency and a frequency threshold, as well as the difference between the current outdoor fan speed and the target speed and a speed change threshold, it determines whether to control the air conditioner to stop reducing its frequency. This method reduces the air conditioner's operating frequency without affecting the outdoor fan's air delivery capacity.

[0102] Figure 3 A flowchart illustrating an air conditioning control optimization method provided in this application embodiment. Figure 3 This application provides a detailed explanation of the steps for determining whether to control the air conditioner to stop reducing its frequency based on the outdoor fan speed and a speed change threshold. For example... Figure 3 As shown, the method includes:

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

[0104] In this step, the target speed is the maximum permissible outdoor fan speed obtained based on noise requirements. However, in addition to noise requirements, outdoor fan speed also affects the user experience. Therefore, to further improve the user experience, the recommended outdoor fan speed can be obtained based on the air conditioner's operating parameters 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 outdoor coil sensor temperature. Therefore, in this embodiment, the recommended outdoor fan speed is obtained based on the inner ring temperature, indoor unit air outlet temperature, and outdoor coil sensor temperature.

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

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

[0108] In this step, the preset relationship is used to indicate the correspondence 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 system obtains the inner ring temperature range to which the current inner ring temperature belongs; the indoor unit outlet temperature range to which it belongs; and the outdoor coil temperature range to which it belongs, based on the current outdoor coil sensor temperature. The system then uses preset relationships to obtain the inner ring temperature range, indoor unit outlet temperature range, and outdoor coil temperature range to determine the corresponding recommended outdoor fan speed.

[0110] S303. Send a prompt message to the user terminal. If feedback is received from the user within a preset time, control the air conditioner to adjust the speed of the outdoor fan to the recommended outdoor fan speed.

[0111] In this step, the prompt information is used to determine whether the user wants the air conditioner to operate at the recommended outdoor fan speed.

[0112] Specifically, once the recommended outdoor fan speed is obtained, a prompt message is generated based on the recommended outdoor fan speed and sent to the user's terminal. If user feedback is received within a preset time, the outdoor fan speed is adjusted according to the recommended outdoor fan speed. If no user feedback is received within the preset time, the outdoor fan is controlled to rotate at the target speed.

[0113] Furthermore, there are multiple ways to adjust the outdoor fan speed. Since the air conditioner's operating frequency has already been reduced, it's best to avoid adjusting the outdoor fan speed by changing the air conditioner's operating frequency. Also, the throttle valve is currently at its threshold opening. If it's necessary to reduce the outdoor fan speed, the throttle valve opening can be reduced. When it's necessary to increase the outdoor fan speed, the air conditioner's operating frequency can be increased, thereby increasing the outdoor fan speed.

[0114] Therefore, it is necessary to obtain the relationship between the recommended outdoor fan speed and the target speed, and then adjust the outdoor fan speed accordingly based on this relationship. The specific operation is as follows:

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

[0116] Specifically, once it is determined that the recommended outdoor fan speed is lower than the target speed, the opening adjustment value is obtained based on the difference between the target speed and the recommended outdoor fan speed. Then, the throttle valve is controlled to reduce its opening based on the opening adjustment value. The specific operation is as follows:

[0117] Obtain the difference between the target speed and the recommended external fan speed, and obtain the ratio of the difference to the speed change threshold;

[0118] Obtain the product of the difference between the opening threshold and the current opening and the ratio, and obtain the opening adjustment value based on the product;

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

[0120] For example, the target speed is 35, and the recommended outdoor 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 outdoor fan speed is 35 - 30 = 5. The ratio is the difference of 5 and the speed change threshold of 10, i.e., 5 / 10 = 0.5. The difference in opening is the difference between the opening threshold of 80 and the current opening of 60, i.e., 80 - 60 = 20. The final calculated opening adjustment value is 0.5 * 20 = 10, which controls the air conditioning flow control valve opening to decrease by 10.

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

[0122] This application provides an air conditioning control optimization method. After the air conditioner stops reducing the frequency of the outdoor fan and the speed recovers to the target speed for a period of time, a recommended outdoor fan speed is obtained based on the current inner loop temperature, the current indoor unit air outlet temperature, and the current outdoor coil sensor temperature. Upon receiving user feedback, the air conditioner is controlled to adjust the outdoor fan speed to the recommended speed. This method improves user comfort and increases user willingness to use the system.

[0123] Figure 4 This is a schematic diagram of the structure of an air conditioning control optimization device provided in an embodiment of this 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 to obtain the air outlet temperature and indoor ambient 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 to obtain the frequency reduction rate based on the air outlet temperature and the indoor ambient temperature, wherein the initial frequency is determined based on the outdoor ambient temperature of the air conditioner outdoor unit.

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

[0126] The determining module 403 is used to control the air conditioner to reduce its operating frequency according to the frequency reduction rate, and continuously acquire the current outdoor fan speed. Based on the current outdoor fan speed and the speed change threshold, it determines whether to control the air conditioner to stop reducing the frequency.

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

[0128] The target rotational speed and the current operating frequency are obtained, wherein the target rotational speed is determined based on a pre-stored noise requirement;

[0129] 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, then it is determined that the air conditioner will stop reducing its frequency.

[0130] If the current operating frequency is equal to the frequency threshold, then the air conditioner is controlled to stop reducing its frequency.

[0131] In one possible implementation, the frequency adjustment module 401 is further configured to:

[0132] The temperature difference between the air outlet temperature and the internal ambient temperature is obtained;

[0133] The frequency reduction rate is obtained based on 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 one possible implementation, the frequency adjustment module 401 is further configured to:

[0135] Control the opening degree of the air conditioner adjustment throttle valve to the opening degree threshold.

[0136] In one possible implementation, 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 outdoor coil sensor temperature of the air conditioner are obtained.

[0138] The recommended outdoor fan speed is obtained according to the preset relationship, which corresponds to the current inner ring temperature, the current indoor unit air outlet temperature and the current outdoor coil sensor temperature. The preset relationship is used to indicate the correspondence between the recommended outdoor fan speed and the current inner ring temperature, the current indoor unit air outlet temperature and the current outdoor coil sensor temperature.

[0139] A prompt message is sent to the user. If feedback is received from the user within a preset time, the air conditioner is controlled to adjust the speed of the outdoor fan to the recommended outdoor fan speed. The prompt message is used to determine whether the user has controlled the air conditioner to operate at the recommended outdoor fan speed.

[0140] In one possible implementation, the speed adjustment module 402 is further configured to:

[0141] If the recommended outdoor fan speed is less than the target speed, then control the opening of the air conditioner's adjusting throttle valve to adjust the outdoor fan speed to the recommended outdoor fan speed;

[0142] If the recommended outdoor fan speed is greater than the target speed, the air conditioner is controlled to increase its operating frequency to adjust the outdoor fan speed to the recommended outdoor fan speed.
