[0042] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiment of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0044] The control method, control device and air conditioner of the air conditioner proposed in the present invention are described below with reference to the accompanying drawings. Among them, before the embodiment of the present invention is described in detail, the entire application scenario is described first. The control method, control device, electronic device and computer-readable storage medium of the air conditioner of the embodiment of the present invention can be applied to the air conditioner locally, and can also be applied to the cloud platform in the Internet field, or other types of cloud platforms in the Internet field, or can also be applied to third-party devices. Among them, the third-party device may include many different types such as mobile phones, tablet computers, notebooks, car computers and other smart terminals.

[0045] The following description only takes the control method applicable to air conditioners as an example. It should be understood that the control method of the embodiment of the present invention can also be applied to cloud platforms and third-party devices.

[0046] It should also be noted that the air conditioner control method proposed in the present invention is universal, that is, the method is applicable to the air conditioner for cooling or heating in a low-temperature environment or a high-temperature environment.

[0047] like Figure 1 As shown, a method for controlling an air conditioner according to a first aspect of the present invention includes:

[0048] Step S1, obtaining the current change of the compressor of the air conditioner;

[0049] Step S2, determining that the current change of the compressor meets the current mutation condition, and then executing the priority control logic on the electronic expansion valve of the air conditioner, wherein the priority control logic includes: adjusting the opening of the electronic expansion valve according to the current change condition.

[0050] According to the control method of the air conditioner according to an embodiment of the present invention, its specific working process is as follows: during the operation of the air conditioner, the controller first obtains the current change of the compressor, wherein the above-mentioned current change refers to the current change of the air conditioner compressor within the set time, which can represent the load change of the compressor within the set time.

[0051] After obtaining the current change of the compressor, the controller further analyzes the current change. By judging whether the current change meets the current mutation condition, it can be judged whether the load of the compressor has a sudden change. Specifically, when the current change condition meets the current mutation condition, it indicates that the load demand of the compressor has a sudden change. At this time, if the original electronic expansion valve opening control logic (that is, the conventional control logic of adjusting the opening according to the superheat) is still followed, since the opening of the electronic expansion valve changes slowly, the refrigerant changes slowly, and the amount of refrigerant cannot meet the working requirements of the compressor. Therefore, in order to match the current sudden load condition of the compressor (that is, the current condition), this method adjusts the opening of the electronic expansion valve based on the priority control logic, that is, directly adjusts the opening of the electronic expansion valve according to the current change condition, so that the opening change of the electronic expansion valve can adapt to the current sudden current condition, ensuring the normal and stable operation of the compressor.

[0052] In the related art, for air-conditioning systems that control superheat through an electronic expansion valve, when the load of the air-conditioning system fluctuates greatly, such as when starting, shutting down, or when the terminal load changes suddenly, the system refrigerant demand circulation volume will change dramatically, but at this time the electronic expansion valve is still adjusting slowly and gradually according to the pressure and temperature. The above-mentioned opening adjustment method can easily cause the refrigerant circulation volume to fail to keep up with the load demand of the compressor, resulting in insufficient refrigerant supply reporting low pressure, excessive refrigerant supply causing compressor liquid shock, or the system requiring too long to stabilize.

[0053] In summary, in order to solve the technical defects existing in the above-mentioned related technologies, the present invention provides a control method for an air conditioner, which obtains the current change of the compressor and controls the opening of the electronic expansion valve with priority control logic when the current change meets the current mutation condition. That is, the opening of the electronic expansion valve is quickly adjusted according to the current change condition, so that the opening change of the electronic expansion valve can adapt to the current mutation current condition, and then the system refrigerant amount can match the current mutation load demand of the compressor, thereby improving the system control stability and reducing the response time.

[0054] According to some embodiments of the present invention, in the step of executing the priority control logic on the electronic expansion valve of the air conditioner after determining that the current change condition of the compressor meets the current mutation condition, the current mutation condition includes:

[0055] The current change value of the compressor within the set monitoring time is greater than the set maximum change value, or the current change proportion of the compressor within the set monitoring time is greater than the set maximum proportion.

[0056] Among them, the current mutation situation refers to the sudden change of current within the set monitoring time. Among them, the current change value within the set monitoring time is greater than the set maximum change value, or the current change proportion within the set monitoring time is greater than the set maximum proportion, which can prove that the current has suddenly occurred, that is, the current change situation meets the above-mentioned current mutation situation.

[0057] It should be explained that the above-mentioned current change ratio refers to the ratio between the current change value after the set monitoring time and the initial value of the current before the set monitoring time. Compared with the current change value, the current change ratio can better reflect whether the current has undergone a sudden change.

[0058] In addition, the above-mentioned set monitoring time, set maximum change value and set maximum proportion are all preset values. The above-mentioned preset values ​​can be specifically selected according to different actual usage scenarios and user needs. The present invention does not make any specific limitations on the specific selected values ​​for setting the monitoring time, setting the maximum change value and setting the maximum proportion.

[0059] According to some embodiments of the present invention, the step of determining that the current change of the compressor meets the current mutation condition and then executing the priority control logic on the electronic expansion valve of the air conditioner specifically includes:

[0060] Determine that the current change ratio of the compressor within the set monitoring time is greater than the set maximum ratio;

[0061] The opening adjustment value of the electronic expansion valve is calculated based on the current change ratio;

[0062] Control the electronic expansion valve to change the opening adjustment value based on the current opening.

[0063] In this embodiment, since the current change proportion can more accurately reflect the sudden change of current than the current change value, in order to obtain a more accurate opening adjustment value, the controller will calculate the opening adjustment value of the electronic expansion valve according to the current change proportion, and then adjust the opening of the electronic expansion valve based on the original opening of the electronic expansion valve, and the adjustment value is the changed opening adjustment value obtained in the above steps. In this way, the opening change of the electronic expansion valve can adapt to the current sudden current situation, so that the system refrigerant amount can match the current sudden load demand of the compressor, thereby improving the system control stability and reducing the response time.

[0064] Further, the step of calculating the opening adjustment value of the electronic expansion valve according to the current change ratio specifically includes:

[0065] Obtain the calculation coefficient and the current opening of the electronic expansion valve;

[0066] The opening adjustment value is calculated based on the product of the current opening, the current change ratio and the calculation coefficient.

[0067] It can be understood that the opening adjustment value is the product of the current opening of the electronic expansion valve, the current change ratio and the calculation coefficient. In this way, after a sudden change in the current, the electronic expansion valve reduces or increases the opening adjustment value that is positively correlated with the current change ratio on the basis of the original opening, so that the changed opening of the electronic expansion valve adapts to the current situation after the sudden change, thereby ensuring the normal operation of the compressor.

[0068] For example, the current opening is marked as m, the current change ratio is marked as x, and the calculation coefficient is marked as p. When the current change ratio of the compressor within the set monitoring time is greater than or equal to the set maximum ratio, the current changes suddenly, and the opening adjustment value a=m×x×p is calculated at this time. At this time, the electronic expansion valve is controlled to obtain an opening adjustment value a that changes immediately based on the current opening m, and switches to normal control logic after maintaining for a certain period of time.

[0069] According to some embodiments of the present invention, after the step of obtaining the current change of the compressor, the air conditioner control method further includes:

[0070] If it is determined that the current change of the compressor does not meet the current mutation condition, then the conventional control logic is executed on the electronic expansion valve of the air conditioner.

[0071] Among them, the conventional control logic includes:

[0072] Obtain the target superheat and actual superheat of the compressor;

[0073] Adjust the opening of the electronic expansion valve according to the target superheat and the actual superheat.

[0074] In this way, when the current change of the compressor does not meet the current mutation condition, that is, the current change value within the set monitoring period is less than the set maximum change value, or the current change proportion within the set monitoring period is less than the set maximum proportion, it can be proved that the current has not mutated, that is, the current change does not meet the above-mentioned current mutation condition.

[0075] When the current conversion situation does not meet the current mutation situation, the opening of the electronic expansion valve is adjusted through conventional control logic, that is, the electronic expansion valve is adjusted according to the superheat, so as to achieve a match between the refrigerant amount and the compressor load and ensure the normal operation of the compressor.

[0076] In some specific embodiments of the present invention, the step of adjusting the opening of the electronic expansion valve according to the target superheat and the actual superheat specifically includes:

[0077] If it is determined that the actual superheat is less than the target superheat, the opening of the electronic expansion valve is controlled to increase;

[0078] If it is determined that the actual superheat is equal to the target superheat, the current opening of the electronic expansion valve is maintained;

[0079] If it is determined that the actual superheat is greater than the target superheat, the opening of the electronic expansion valve is controlled to decrease.

[0080] It can be understood that when the actual superheat is less than the target superheat, it means that the refrigerant circulation volume in the system is insufficient to meet the refrigerant demand of the compressor, so it is necessary to control the opening of the electronic expansion valve to increase in order to increase the refrigerant circulation volume in the system; when the actual superheat is greater than the target superheat, it means that the refrigerant circulation volume in the system is more than the refrigerant demand of the compressor, so it is necessary to control the opening of the electronic expansion valve to decrease in order to reduce the refrigerant circulation volume in the system; when the actual superheat is equal to the target superheat, it means that the refrigerant circulation volume in the system just matches the refrigerant demand of the compressor, so there is no need to adjust the opening of the electronic expansion valve, and it is only necessary to control the electronic expansion valve to maintain the current opening for operation.

[0081] It should be pointed out that the above-mentioned target superheat is a preset value. The above-mentioned preset value can be specifically selected as different values ​​according to the actual usage scenarios and user needs. The present invention does not make any specific limitation on the specific selected value of the target superheat.

[0082] According to some embodiments of the present invention, after determining that the current change of the compressor meets the current mutation condition, the control method further includes:

[0083] Control the electronic expansion valve to operate continuously at the changed opening degree for at least the set opening time;

[0084] After the set start time ends, the subsequent current change of the compressor is obtained;

[0085] According to the subsequent current changes, the priority control logic or the conventional control logic is selected to control the opening of the electronic expansion valve.

[0086] It can be understood that after the priority control logic is executed, the compressor may still experience a sudden current change. Therefore, it is necessary to continue to obtain the subsequent current changes of the compressor, and based on the subsequent current changes, determine the control logic that needs to be selected in the subsequent control and control the opening of the electronic expansion valve. Among them, the control logic includes priority control logic and conventional control logic.

[0087] In this way, it can be ensured that the compressor can achieve a match between the amount of refrigerant and the load demand during the entire operation process, thereby ensuring the service life of the compressor.

[0088] In some specific embodiments of the present invention, the step of selecting a priority control logic or a conventional control logic to control the opening of the electronic expansion valve according to subsequent current changes specifically includes:

[0089] If the subsequent current changes meet the current mutation condition, the opening of the electronic expansion valve is controlled according to the priority control logic;

[0090] Alternatively, if the subsequent current change does not satisfy the current mutation condition, the opening of the electronic expansion valve is controlled according to conventional control logic.

[0091] For example, after the set opening time ends, if the current change value within the set monitoring time is greater than or equal to the set maximum change value, or the current change proportion within the set monitoring time is greater than or equal to the set maximum proportion, the opening of the electronic expansion valve is controlled according to the priority control logic, that is, the opening adjustment value is calculated according to the product of the current opening, the current change proportion and the calculation coefficient, and the electronic expansion valve is controlled to change the opening adjustment value based on the current opening.

[0092] After the set opening time ends, if the current change value within the set monitoring time is less than the set maximum change value, or the current change proportion within the set monitoring time is less than the set maximum proportion, the opening of the electronic expansion valve is controlled according to the conventional control logic, that is, the opening of the electronic expansion valve is adjusted according to the target superheat and the actual superheat.
