When the following description refers to accompanying drawings, unless otherwise specified, the same numbers in different drawings represent the same or similar elements. The implementations described in the following example embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0048] It should be noted that all actions of obtaining signals, information or data in the present disclosure are performed in compliance with the corresponding data protection regulations and policies of the country where the device is located, and with the authorization given by the owner of the corresponding device.

[0049] Figure 1 FIG. 1 is a flowchart illustrating a method for modifying the bandwidth of a current loop according to an example embodiment. As shown in FIG. 1, the method includes the following steps. Figure 1

[0050] Step S110, obtaining the high-pressure side pressure of the refrigerant system at the current time, and obtaining the outer ring temperature of the compressor at the current time.

[0051] The outer ring temperature can also be referred to as the outdoor ambient temperature, but is not limited thereto.

[0052] In some embodiments, the method can be applied in an air conditioner.

[0053] ​Wherein, corresponding to different modes of the air conditioner, such as a refrigeration mode and a heating mode, the refrigerant flow directions are different; in the refrigeration mode, the discharge pipeline of the compressor is connected to the high-pressure side of the refrigerant system; in the heating mode, the suction pipeline of the compressor is connected to the high-pressure side of the refrigerant system.

[0054] In some embodiments, the high-pressure side pressure of the refrigerant system is determined according to the mode of the air conditioner, the pipeline of the compressor corresponding to the high-pressure side of the refrigerant system is obtained, and the refrigerant pressure corresponding to the pipeline is obtained to determine the high-pressure side pressure of the refrigerant system; or in some embodiments, the refrigerant pressures corresponding to the discharge pipeline and the suction pipeline of the compressor are obtained respectively, and the high-pressure side pressure of the refrigerant system is determined according to the pressure value of the one corresponding to which is higher.

[0055] It should be noted that in the embodiments of the present disclosure, the specific manner of obtaining the high-pressure side pressure of the refrigerant system and obtaining the outer ring temperature of the compressor is not limited; for example, a pressure sensor can be used for sampling to obtain the high-pressure side pressure of the refrigerant system, and a temperature sensor can be used for sampling to obtain the outer ring temperature of the compressor.

[0056] In some embodiments, the high-pressure side pressure of the refrigerant system and the outer ring temperature of the compressor are obtained every preset time interval and recorded; in some embodiments, the preset time interval can be 1 min.

[0057] Step S120, in response to the outer ring temperature being greater than or equal to a preset outer ring temperature threshold, determining the load state of the compressor at the current time according to the high-pressure side pressure.

[0058] In some embodiments, the load state of the compressor represents the load condition of the compressor, for example, it can represent that the load is too high, the load is high, the load is moderate, or the load fluctuation is small, etc.

[0059] In some embodiments, the outer ring temperature threshold can be 50℃ or greater than 50℃; or in some embodiments, the outer ring temperature threshold can be 53℃ or greater than 53℃.

[0060] Step S130, correcting the current loop bandwidth of the compressor at the current time according to the load state.

[0061] Wherein, the current loop bandwidth is corrected according to different load states of the compressor.

[0062] Among them, the current loop, also known as the current feedback system, generally refers to the way of connecting the output current to the processing link in the form of positive feedback or negative feedback, to improve the stability of the current and improve the performance of the system; the current loop bandwidth is a driving control parameter, which represents the maximum sinusoidal signal frequency that the current loop can respond to. In the driving control of the compressor and the air conditioner, the larger the current loop bandwidth, the faster the current loop responds to the corresponding command. Under different load states and load change states of the compressor, the current loop bandwidth may have different adaptive parameter values.

[0063] The current loop bandwidth correction method provided by the embodiments of the present disclosure includes: obtaining the high-pressure side pressure of the refrigerant system at the current moment, and obtaining the outer ring temperature of the compressor at the current moment; in response to the outer ring temperature being greater than or equal to a preset outer ring temperature threshold, determining the load state of the compressor at the current moment according to the high-pressure side pressure; and correcting the current loop bandwidth of the compressor at the current moment according to the load state. Therefore, the load state of the compressor is determined according to the outer ring temperature and the high-pressure side pressure of the refrigerant system, and the current loop bandwidth of the compressor is corrected according to the load state, so that the current loop bandwidth is adapted to the running state of the compressor. Compared with the related art, which lacks dynamic calculation and correction of the current loop bandwidth, the scheme of the embodiments of the present disclosure can dynamically determine the adaptive current loop bandwidth corresponding to different load states, realize accurate control of the current loop bandwidth, improve the reliability of the compressor operation, and ensure the operation effect.

[0064] Figure 2 is a flow chart of another current loop bandwidth correction method according to an exemplary embodiment. As shown in Figure 2 , the method includes the following steps.

[0065] Step S210, obtaining the high-pressure side pressure of the refrigerant system at the current moment, and obtaining the outer ring temperature of the compressor at the current moment.

[0066] Step S220, in response to the outer ring temperature being greater than or equal to a preset outer ring temperature threshold, determining the load state of the compressor at the current moment according to the high-pressure side pressure.

[0067] Step S231, determining the correction value corresponding to the current loop bandwidth at the current moment according to the load state.

[0068] Step S232, correcting the current loop bandwidth according to the correction value.

[0069] Among them, the corresponding correction value is determined according to the different load states of the compressor, and the current loop bandwidth is corrected according to the determined correction value; the correction value can also be referred to as a correction threshold, which is not limited thereto.

[0070] In some embodiments, the target current loop bandwidth is determined according to the current loop bandwidth of the compressor at the current moment and the correction value, so as to correct the current loop bandwidth of the compressor at the current moment; in some embodiments, the target current loop bandwidth is determined according to the sum of the current loop bandwidth of the compressor at the current moment and the correction value.

[0071] Therefore, based on the scheme of the embodiments of the present disclosure, the load state of the compressor can be determined according to the outer ring temperature and the high-pressure side pressure of the refrigerant system, and the corresponding correction value is determined according to the load state, so as to dynamically correct the current loop bandwidth of the compressor, so that the current loop bandwidth is adapted to the current operating state of the compressor, the precise control of the current loop bandwidth is realized, the reliability of the compressor operation is improved, and the operation effect is ensured.

[0072] Figure 3 An implementation method flowchart of step S231 in the embodiments of the present disclosure is shown in FIG. 8. The method is based on the method shown in FIG. 7, and the method shown in FIG. 8 is an optional implementation scheme of the method shown in FIG. 7; as shown in FIG. 8, step S231 includes: Figure 2 Figure 3 As shown in FIG. 8, step S231 includes:

[0073] Step S2311, in response to the load state being the first preset state, determining that the correction value is a preset first bandwidth correction value.

[0074] Step S2312, in response to the load state being the second preset state, determining that the correction value is a preset second bandwidth correction value.

[0075] In the embodiments of the present disclosure, the second bandwidth correction value is less than the first bandwidth correction value.

[0076] In the embodiments of the present disclosure, the corresponding correction value is determined according to different load states; the bandwidth correction value can also be referred to as a bandwidth correction threshold, which is not limited thereto.

[0077] Figure 4 An implementation method flowchart of step S220 in the embodiments of the present disclosure is shown in FIG. 6. As shown in FIG. 6, step S220 includes: Figure 4

[0078] Step S221, in response to the high-pressure side pressure being greater than or equal to a preset first pressure threshold, determining that the load state is a first preset state.

[0079] In some embodiments, the first preset state represents that the load of the compressor is too high or relatively high.

[0080] In some embodiments, the first pressure threshold can be 4.4 MPa or greater than 4.4 MPa; in some embodiments, the first bandwidth correction value can be 600 or greater than 600. ​​

[0081] In some embodiments, as shown in FIG. 2, the step S220 of determining the load state of the compressor at the current time according to the high-pressure side pressure comprises: Figure 4

[0082] The step S222 determines the load state as a second preset state in response to the high-pressure side pressure being less than a first preset pressure threshold and greater than or equal to a second preset pressure threshold.

[0083] The second pressure threshold is less than the first pressure threshold.

[0084] In some embodiments, the first preset state represents an over-high load of the compressor, the second preset state represents a high load of the compressor, and the second bandwidth correction value is less than the first bandwidth correction value.

[0085] In some embodiments, the second pressure threshold can be 4.0 MPa or greater than 4.0 MPa, and the second bandwidth correction value can be 250 or greater than 250.

[0086] In some embodiments, the step S220 of determining the load state of the compressor at the current time according to the high-pressure side pressure comprises: determining the load state as a third preset state in response to the high-pressure side pressure being less than the second pressure threshold, and determining no correction of the current loop bandwidth or determining the correction value as zero in response to the load state being the third preset state.

[0087] It can be understood that the above embodiments can also be applied to the step S120 and other steps and embodiments associated therewith.

[0088] Therefore, based on the scheme of the embodiments of the present disclosure, the current load state of the compressor can be determined according to the high-pressure side pressure of the refrigerant system, the corresponding correction value is determined for different load states, and the current loop bandwidth of the compressor is dynamically corrected.

[0089] Figure 5 FIG. 3 is a flowchart of another method for correcting the current loop bandwidth according to an exemplary embodiment. As shown in FIG. 3, the method comprises the following steps. Figure 5

[0090] The step S311 acquires a high-pressure side pressure signal of the refrigerant system and acquires an outer ring temperature signal of the compressor.

[0091] It should be noted that in the embodiments of the present disclosure, the specific manner of acquiring the outer ring temperature signal and the high-pressure side pressure signal is not limited; for example, the sampling signals transmitted back by the temperature sensor and the pressure sensor based on the sampling of the mainboard of the outdoor unit of the air conditioner can be received to acquire the outer ring temperature signal and the high-pressure side pressure signal.

[0092] ​​Step S312, filtering and analog-digital conversion are performed on the high-pressure side pressure signal and the outer ring temperature signal to obtain the high-pressure side pressure and the outer ring temperature.

[0093] The high-pressure side pressure and the outer ring temperature are obtained by processing the high-pressure side pressure signal and the outer ring temperature signal, respectively; in some embodiments, filtering is performed by sampling and averaging the two signals for multiple times, for example, by sampling and averaging the two signals for 32 times.

[0094] Step S320, in response to the outer ring temperature being greater than or equal to a preset outer ring temperature threshold, determining the load state of the compressor at the current time according to the high-pressure side pressure.

[0095] Step S330, correcting the current loop bandwidth of the compressor at the current time according to the load state.

[0096] Figure 6 An implementation method flowchart of step S120 in the embodiments of the present disclosure is shown in FIG. 12. Figure 6 As shown in FIG. 12, before the step of determining the load state of the compressor at the current time according to the high-pressure side pressure in step S120, the following steps are included:

[0097] Step S123, obtaining the running time of the compressor.

[0098] It should be noted that the specific manner of obtaining the running time of the compressor is not limited in the embodiments of the present disclosure; for example, the running time of the compressor can be obtained based on a timer.

[0099] In step S120, the step of determining the load state of the compressor at the current time according to the high-pressure side pressure includes:

[0100] Step S124, in response to the running time being greater than or equal to a preset running time threshold, determining the load state according to the high-pressure side pressure.

[0101] The running time being greater than or equal to the preset running time threshold indicates that the compressor is in a stable running phase, and the overall load of the system tends to be stable, so the load state can be determined according to the high-pressure side pressure to control the current loop bandwidth of the compressor.

[0102] In some embodiments, the running time threshold can be 10 minutes or greater than 10 minutes; or in some embodiments, the running time threshold can be 12 minutes or greater than 12 minutes.

[0103] It can be understood that the above-mentioned implementation manners can also be applied to step S220, step S320, and other steps associated with the above-mentioned steps and embodiments.

[0104] Thus, based on the running time of the compressor, the current loop bandwidth of the compressor is dynamically corrected after the compressor is stably running, thereby ensuring the reliability and stability of the current loop bandwidth correction.

[0105] The correction method of the current loop bandwidth provided by the present disclosure is described below in combination with actual applications.

[0106] Figure 7 is a flowchart of still another correction method of the current loop bandwidth according to an exemplary embodiment. As shown in the figure, the method comprises the following steps. Figure 7

[0107] In step S411, a high-pressure side pressure signal of the refrigerant system is acquired, and an outer ring temperature signal of the compressor is acquired.

[0108] In step S412, the high-pressure side pressure signal and the outer ring temperature signal are subjected to filtering processing and analog-to-digital conversion, thereby obtaining the high-pressure side pressure and the outer ring temperature.

[0109] In the above steps, the high-pressure side pressure is acquired and recorded every preset time interval. Exemplarily, the preset time interval is 1 min, i.e., the interval between the current time and the previous time is 1 min.

[0110] In step S413, the running time of the compressor is acquired.

[0111] In step S414, it is determined whether the outer ring temperature is greater than or equal to a preset outer ring temperature threshold value and whether the running time is greater than or equal to a preset running time threshold value.

[0112] Exemplarily, the outer ring temperature threshold value is 53℃, and the running time threshold value is 12 min.

[0113] In step S414, if the outer ring temperature is greater than or equal to the outer ring temperature threshold value and the running time is greater than or equal to the running time threshold value, step S421 is executed; if the outer ring temperature is less than the outer ring temperature threshold value or the running time is less than the running time threshold value, the current current loop bandwidth is maintained unchanged, step S412 is continuously executed, and the high-pressure side pressure of the refrigerant system is acquired and recorded at the next time, the outer ring temperature of the compressor is acquired, and the running time of the compressor acquired before is updated.

[0114] In step S421, it is determined whether the high-pressure side pressure is greater than or equal to a preset first pressure threshold value.

[0115] Exemplarily, the first pressure threshold value is 4.4 MPa.

[0116] In step S421, if the high-pressure side pressure is greater than or equal to the first pressure threshold value, step S4311a is executed; if the high-pressure side pressure is less than the first pressure threshold value, step S422 is executed.​

[0117] In step S4311a, the correction value is determined as a preset first bandwidth correction value.

[0118] For example, the first bandwidth correction value is 600.

[0119] In step S4312a, the current loop bandwidth is corrected according to the correction value.

[0120] In step S422, it is determined whether the high-pressure side pressure is greater than or equal to a preset second pressure threshold value.

[0121] In step S422, if the high-pressure side pressure is greater than or equal to the second pressure threshold value, step S4311b is executed; if the high-pressure side pressure is less than the second pressure threshold value, the current current loop bandwidth is maintained unchanged, and step S412 is continued to be executed, waiting until the next time, obtaining and recording the high-pressure side pressure of the refrigerant system, obtaining the outer ring temperature of the compressor, and updating the running time of the compressor obtained before.

[0122] In step S4311b, the correction value is determined as a preset second bandwidth correction value.

[0123] For example, the second bandwidth correction value is 250.

[0124] In step S4312b, the current loop bandwidth is corrected according to the correction value.
