[0049] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0050] In the description of the present disclosure, the terms used, such as "first", "second", etc., are used to distinguish similar objects and do not have to be understood as a specific order or sequence. In addition, in the description with reference to the accompanying drawings, the same symbols in different drawings represent the same elements unless otherwise stated.

[0051] Although operations or steps are described in a specific order in the drawings in the embodiments of the present disclosure, it should not be understood that it is required to perform these operations or steps in the specific order shown or in a serial order, or to perform all the operations or steps shown to obtain the desired results. In the embodiments of the present disclosure, these operations or steps can be performed in series; these operations or steps can also be performed in parallel; or some of these operations or steps can be performed.

[0052] At present, during the operation of air conditioners, when the indoor temperature reaches the set temperature, the operating parameters of the air conditioner usually tend to stabilize. At this time, if there is no abnormal change in the load, the room temperature will be controlled near the set temperature. Therefore, if the room temperature suddenly rises under cooling conditions, or if the room temperature suddenly drops under heating conditions, it is very likely that the user has opened the doors and windows, causing outdoor air to enter and increase the load. At this time, closed-loop regulation is required, such as PID control (proportional-integral-derivative control) or fuzzy control. However, the frequency increase of closed-loop regulation usually requires a certain reaction time, resulting in large fluctuations in the room temperature and a long recovery time for the room temperature.

[0053] Figure 1 is a flow chart of a method for controlling an air conditioner according to an exemplary embodiment. Figure 1 As shown, the air conditioner control method is used in the air conditioner and includes the following steps.

[0054] In step S110, it is determined that the environment in which the air conditioner is located meets a first preset condition, and a first temperature change difference of the air conditioner within a first time period is obtained.

[0055] In the embodiment of the present disclosure, before the air conditioner reaches the temperature, the frequency of the compressor is basically in a high-frequency operation state, and the capacity compensation is small; after the air conditioner reaches the temperature, the frequency tends to be reduced to a temperature frequency, so that the capacity output is equivalent to the indoor load, so as to achieve the effect of temperature control. In this case, the output capacity of the air conditioner remains unchanged, and the outdoor ambient temperature has not changed suddenly. If the indoor temperature suddenly rises or falls, it means that the air conditioner has generated additional load, and the additional load is most likely caused by the user opening the doors and windows for ventilation, or entering and exiting the room. Therefore, in order to avoid room temperature fluctuations caused by the user suddenly opening the doors and windows, the embodiment of the present disclosure can first determine whether the environment in which the air conditioner is located meets the first preset condition.

[0056] As an optional method, when it is determined that the environment in which the air conditioner is located meets the first preset condition, the embodiment of the present disclosure can obtain a first temperature change difference of the air conditioner within the first time period. The first temperature change difference can be a change difference of the indoor ambient temperature. Here, the first preset condition can be that the output capacity of the air conditioner remains unchanged and the outdoor ambient temperature does not change suddenly.

[0057] In some embodiments, the first temperature change difference within the first time period may be a change difference of the indoor ambient temperature within the first time period. Exemplarily, when it is determined that the environment in which the air conditioner is located satisfies the first preset condition, monitor whether the change of the indoor ambient temperature within 1 minute exceeds the first preset value. If it is determined that the first temperature change difference exceeds the first preset value, the frequency correction value of the compressor in the air conditioner is obtained based on the first temperature change difference, that is, enter step S120.

[0058] As a specific implementation, the air conditioner is currently in different modes, and the corresponding method of obtaining the first temperature change difference is also different. Specifically, when the air conditioner is in cooling mode, the first temperature change difference can be the indoor ambient temperature at the current moment minus the indoor ambient temperature before the preset time. For example, the first temperature change difference can be the indoor ambient temperature at the current moment minus the indoor ambient temperature 1 minute ago. When the air conditioner is in heating mode, the first temperature change difference can be the indoor ambient temperature before the preset time minus the indoor ambient temperature at the current moment. For example, the first temperature change difference can be the indoor ambient temperature 1 minute ago minus the indoor ambient temperature at the current moment.

[0059] As an example, when the air conditioner is in heating mode, the indoor ambient temperature obtained 1 minute ago is 26°C, and the current indoor ambient temperature is 24°C. At this time, the first temperature change difference is 26°C-24°C=2°C.

[0060] As another example, when the air conditioner is in cooling mode, the current indoor ambient temperature is 29°C, and the indoor ambient temperature obtained 1 minute ago is 26°C. At this time, the first temperature change difference is 29°C-26°C=3°C.

[0061] In step S120, it is determined that the first temperature change difference is greater than a first preset value, and a frequency correction value of the compressor in the air conditioner is obtained based on the first temperature change difference.

[0062] As an optional method, after obtaining the first temperature change difference, the embodiment of the present disclosure can determine whether the first temperature change difference is greater than a first preset value. If it is determined that the first temperature change difference is greater than the first preset value, a frequency correction value of the compressor in the air conditioner is obtained based on the first temperature change difference. Here, the first preset value can be represented by b, such as the first preset value can be 0.5°C.

[0063] Specifically, the disclosed embodiment can obtain the indoor ambient temperature change of the air conditioner in the first time period according to the first temperature change difference. Here, the indoor ambient temperature change can be the ratio between the first temperature change difference and the first time period. For example, if the first temperature change difference is 3°C and the first time period is 1 minute, the indoor ambient temperature change is 3°C / 1min=3.

[0064] On this basis, the embodiment of the present disclosure can obtain the frequency correction value of the compressor based on the outdoor ambient temperature, indoor ambient temperature and indoor ambient temperature change of the air conditioner. Specifically, the calculation formula of the frequency correction value of the compressor can be: △F=k*|T1-T2|*(△T2 / t).

[0065] Among them, △F is the increase value of the compressor operating frequency, k is the frequency correction coefficient, which can be related to the size of the compressor, T1 is the outdoor ambient temperature, T2 is the indoor ambient temperature, △T2 / t is the change in indoor ambient temperature, and the change in indoor ambient temperature can be obtained based on the first temperature change difference and the first time period, that is, △T2 / t can be the change in indoor ambient temperature within the first time period.

[0066] In a specific implementation, in the process of obtaining the frequency correction value of the compressor based on the outdoor ambient temperature, indoor ambient temperature and indoor ambient temperature change of the air conditioner, the air conditioner can first obtain a frequency correction coefficient, which has a certain corresponding relationship with the size of the compressor.

[0067] Specifically, when obtaining the frequency correction coefficient, the embodiment of the present disclosure may first obtain the size of the compressor, and on this basis, obtain the frequency correction coefficient corresponding to the size of the compressor. Here, the size of the compressor and the frequency correction coefficient may be inversely proportional, that is, the larger the compressor, the smaller the corresponding frequency correction coefficient may be. Conversely, the smaller the compressor, the larger the corresponding frequency correction coefficient may be.

[0068] Optionally, the frequency correction coefficient can also be determined according to the size of the door and window. Specifically, when obtaining the frequency correction coefficient, the embodiment of the present disclosure can first obtain the size of the door and window. On this basis, the frequency correction coefficient corresponding to the size of the door and window is obtained. Here, the size of the door and window can be manually input by the user, that is, the air conditioner can be bound to a specified application on the electronic device, and the user can input the size of the door and window through the specified application.

[0069] Optionally, the size of doors and windows can also be determined by the change difference of indoor ambient temperature and the temperature difference between indoor ambient temperature and outdoor ambient temperature, that is, the corresponding size of doors and windows is determined by monitoring the change difference of indoor ambient temperature and the temperature difference between indoor ambient temperature and outdoor ambient temperature.

[0070] Optionally, the size of the door and window can also be obtained by an infrared sensor, where the infrared sensor can be a millimeter wave or a radar. After the infrared sensor obtains the size of the door and window, the infrared sensor can send the size of the door and window to the air conditioner, and on this basis, the air conditioner can obtain the frequency correction coefficient corresponding to the size of the door and window.

[0071] It should be noted that the disclosed embodiment can use any one of the above methods to obtain the door and window size, or can combine at least one of the above methods to obtain the door and window size. The specific method of obtaining the door and window size is not explicitly limited here and can be selected according to actual conditions.

[0072] It should be noted that the size of the door and window can be the size of the window in the room where the air conditioner is located, or the size of the door in the room where the air conditioner is located, or the size of the door and window in the room where the air conditioner is located. The embodiment of the present disclosure mainly focuses on the size of the window. In addition, the size of the door and window can be the actual size of the door and window, or the size of the door and window actually opened when the user opens the door and window.

[0073] In step S130, a target frequency for the operation of the compressor is determined according to the frequency correction value, and the compressor is controlled to operate at the target frequency.

[0074] As an optional method, after identifying that the doors and windows are open, in order to reduce the fluctuation of indoor temperature, the compensation capacity of the air conditioner is equivalent to the load to stabilize the temperature more quickly. Therefore, the embodiment of the present disclosure analyzes the load introduced by the opening of doors and windows. This part of the load is mainly caused by the heat exchange and replacement of indoor and outdoor air. The air conditioner can match the load with the work done by the compressor to derive an adaptive compensation frequency, which can be used as a frequency correction value.

[0075] Optionally, after the frequency correction value is obtained, the embodiment of the present disclosure can determine the target frequency of the compressor operation according to the frequency correction value, and on this basis, control the compressor to operate at the target frequency.

[0076] As an optional method, when the environment in which the air conditioner is located meets the first preset condition, the frequency of the compressor tends to be stable, that is, the frequency of the compressor is basically unchanged, and the frequency of the compressor can be used as the first frequency. When the target frequency of the compressor operation is determined according to the frequency correction value, the target frequency can be the sum of the frequency correction value and the first frequency.

[0077] As an example, the target frequency F = F 运行频率 +△F 频率修正值 Among them, F 运行频率 It can be the first frequency mentioned above, △F 频率修正值 It can be a door and window load correction.

[0078] When it is determined that the environment in which the air conditioner is located satisfies a first preset condition and that the change difference of the indoor ambient temperature is greater than the first preset difference, the present invention obtains a frequency correction value of the compressor in the air conditioner based on the first temperature change difference, and on this basis, determines the target frequency of the compressor operation according to the frequency correction value, and controls the compressor to operate at the target frequency, so as to quickly respond to room temperature fluctuations, thereby reducing temperature fluctuations to ensure the user experience.

[0079] Figure 2 is a flow chart of a method for controlling an air conditioner according to an exemplary embodiment. Figure 2 As shown, the air conditioner control method is used in the air conditioner and includes the following steps.

[0080] In step S210, the indoor environment temperature corresponding to the air conditioner is obtained.

[0081] As an optional method, after the air conditioner is turned on, the embodiment of the present disclosure can obtain the indoor ambient temperature corresponding to the air conditioner, and on this basis, determine whether the indoor ambient temperature is less than or equal to the set temperature, that is, enter step S220.

[0082] In step S220, based on the working mode of the air conditioner, it is determined whether the indoor ambient temperature corresponding to the air conditioner and the set temperature meet the second preset condition, and at least one of the frequency of the compressor, the speed of the internal fan and the speed of the external fan in the second time period is monitored.

[0083] In the embodiment of the present disclosure, whether the indoor ambient temperature corresponding to the air conditioner satisfies the second preset condition with the set temperature is determined based on the working mode of the air conditioner, mainly to determine whether the indoor ambient temperature reaches the set temperature. Different working modes of the air conditioner correspond to different ways of determining whether the indoor ambient temperature reaches the set temperature, that is, in the embodiment of the present disclosure, whether the indoor ambient temperature corresponding to the air conditioner satisfies the second preset condition with the set temperature can be determined based on the working mode of the air conditioner.

[0084] Specifically, when it is determined that the working mode of the air conditioner is the cooling mode, if it is determined that the indoor ambient temperature is less than or equal to the set temperature, the embodiment of the present disclosure can determine that the indoor ambient temperature and the set temperature meet the second preset condition. At this time, the air conditioner can monitor at least one of the frequency of the compressor, the speed of the internal fan, and the speed of the external fan in the second time period.

[0085] In addition, when it is determined that the working mode of the air conditioner is the heating mode, if it is determined that the indoor ambient temperature is greater than or equal to the set temperature, the embodiment of the present disclosure can determine that the indoor ambient temperature and the set temperature meet the second preset condition. At this time, the air conditioner can monitor at least one of the frequency of the compressor, the speed of the internal fan, and the speed of the external fan in the second time period.

[0086] Optionally, in the process of determining whether the indoor ambient temperature corresponding to the air conditioner and the set temperature meet the second preset condition based on the working mode of the air conditioner, the embodiment of the present disclosure can obtain a first temperature difference, which can be the difference between the indoor temperature and the set temperature. When the working mode of the air conditioner is the cooling mode, the first temperature difference can be the indoor ambient temperature minus the set temperature; when the working mode of the air conditioner is the heating mode, the first temperature difference can be the set temperature minus the indoor ambient temperature. Here, the set temperature can be a temperature input by the user according to personal needs.

[0087] On this basis, it is determined whether the first temperature difference is less than or equal to the temperature threshold. If it is determined that the first temperature difference is less than or equal to the temperature threshold, it means that the indoor ambient temperature reaches the set temperature. At this time, the air conditioner can monitor at least one of the frequency of the compressor, the speed of the internal fan, and the speed of the external fan. Here, the temperature threshold can be 0°C.

[0088] During the cooling or heating operation of the air conditioner, after the room temperature reaches the set temperature input by the user, if the user suddenly opens the doors and windows, the room temperature will fluctuate. This scenario can be called a preset scenario. In order to solve this problem, the embodiment of the present disclosure can obtain the frequency correction value of the air conditioner compressor based on the temperature change difference, and obtain the target frequency of the compressor operation based on the frequency correction value. The compressor can respond quickly to room temperature fluctuations when it runs at the target frequency, thereby reducing the impact of the fluctuations on the user.

[0089] In order to more accurately determine whether the scene in which the air conditioner is located is a preset scene, the embodiment of the present disclosure can determine whether the indoor ambient temperature corresponding to the air conditioner and the set temperature meet a second preset condition based on the working mode of the air conditioner. If it is determined that the second preset condition is met, the air conditioner can monitor at least one of the frequency of the compressor, the speed of the internal fan, and the speed of the external fan within the second time period.

[0090] In step S230, when at least one of the frequency of the compressor, the speed of the internal fan and the speed of the external fan remains unchanged, it is determined that the environment in which the air conditioner is located meets the first preset condition, and the first temperature change difference of the air conditioner in the first time period is obtained.

[0091] As an optional manner, in the process of monitoring at least one of the frequency of the compressor, the rotation speed of the inner fan, and the rotation speed of the outer fan in the second time period, the air conditioner can determine whether at least one of the frequency of the compressor, the rotation speed of the inner fan, and the rotation speed of the outer fan in the second time period remains unchanged. If it is determined that at least one of the frequency of the compressor, the rotation speed of the inner fan, and the rotation speed of the outer fan remains unchanged in the second time period, the embodiment of the present disclosure can determine that the environment in which the air conditioner is located meets the first preset condition.

[0092] Specifically, when it is determined that the frequency of the compressor remains unchanged during the second time period, it is determined that the environment in which the air conditioner is located meets the first preset condition; when it is determined that the speed of the fan remains unchanged during the second time period, it is determined that the environment in which the air conditioner is located meets the first preset condition; when it is determined that the speed of the fan remains unchanged during the second time period, it is determined that the environment in which the air conditioner is located meets the first preset condition.

[0093] Optionally, when it is determined that the frequency of the compressor and the speed of the internal fan remain unchanged during the second time period, it is determined that the environment in which the air conditioner is located meets the first preset condition; when it is determined that the speed of the fan and the speed of the external fan remain unchanged during the second time period, it is determined that the environment in which the air conditioner is located meets the first preset condition; when it is determined that the speed of the internal and external fans and the frequency of the compressor remain unchanged during the second time period, it is determined that the environment in which the air conditioner is located meets the first preset condition.

[0094] Optionally, when it is determined that the frequency of the compressor, the rotation speed of the inner fan and the rotation speed of the outer fan remain unchanged during the second time period, it is determined that the environment in which the air conditioner is located meets the first preset condition.

[0095] As another optional method, when determining that at least one of the frequency of the compressor, the speed of the internal fan, and the speed of the external fan remains unchanged, the embodiment of the present disclosure can also obtain a second temperature change difference of the air conditioner in the second time period, wherein the second temperature change difference can be a change difference of the outdoor ambient temperature. Here, the second time period can be represented by c, such as the second time period can be 10 minutes.

[0096] On this basis, it is determined whether the second temperature change difference is less than the second preset value. If it is determined that the second temperature change difference is less than the second preset value, it is determined that the environment where the air conditioner is located meets the first preset condition. Here, the second preset value can be represented by a, such as the second preset value can be 1°C.

[0097] In addition, the second temperature change difference may be the difference between the maximum outdoor ambient temperature and the minimum outdoor ambient temperature in the second time period. For example, if the maximum outdoor ambient temperature is 37°C and the minimum outdoor ambient temperature is 36.5°C within 10 minutes, the second temperature change difference is 37°C-36.5°C=0.5°C.

[0098] It should be noted that step S210 to step S230 may be executed simultaneously or sequentially, and the present disclosure does not limit the execution order of the steps.

[0099] In step S240, it is determined that the first temperature change difference is greater than a first preset value, and a frequency correction value of the compressor in the air conditioner is obtained based on the first temperature change difference.

[0100] In step S250, a target frequency for the compressor to operate is determined according to the frequency correction value, and the compressor is controlled to operate at the target frequency.

[0101] The specific implementation of step S240 to step S250 has been described in detail in the above embodiment, and will not be repeated here.

[0102] In some embodiments, after controlling the compressor to operate at the target frequency, the embodiment of the present disclosure may also reacquire the first temperature change difference. On this basis, if it is determined that the first temperature change difference is greater than or equal to the temperature threshold, the target frequency is acquired again until the first temperature change difference is less than the temperature threshold. Optionally, when it is determined that the first temperature change difference is less than the temperature threshold, the embodiment of the present disclosure may control the compressor to operate at the first frequency. Here, the first frequency may be the frequency of the compressor that remains unchanged.

[0103] As a specific implementation method, in order to better illustrate the control process of the air conditioning temperature, the present disclosure embodiment provides the following Figure 3 The example diagram shown is Figure 3 It is known that after the air conditioner is turned on and operated, the operating frequency of the compressor can be controlled normally. At this time, if it is determined that the first temperature difference △T is less than or equal to 0°C, it is further determined whether the frequency, the speed of the internal extension, and the speed of the external extension have not changed in the second time period. If it is determined that the frequency, the speed of the internal extension, and the speed of the external extension have not changed in the second time period, the embodiment of the present disclosure can obtain the second temperature change difference △T 外环 , the second temperature change difference △T 外环 It can be the maximum outdoor ambient temperature max(T in the second time period) 外环 ) and the minimum outdoor ambient temperature min(C time T 外环 )

[0104] On this basis, if the second temperature change difference △T is determined 外环 If it is less than a, then continue to determine the first temperature change difference △T 内环 Is it greater than b? If the first temperature change difference △T is determined 内环 If it is greater than b, the frequency correction value △F of the compressor is obtained. 开门窗负荷修正 , and based on this frequency correction value △F 开门窗负荷修正 and the first frequency F 运行频率 The target frequency F is calculated.
