Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically to a compressor frequency adjustment method, device, air conditioning equipment, and storage medium. Background Technology

[0002] Air conditioners primarily use a compressor to supply refrigerant pressure, causing the refrigerant to circulate within the system for heat exchange, thus achieving temperature regulation. During operation, the compressor's frequency is limited by frequency thresholds, such as upper and lower frequency limits. These thresholds are typically preset at the factory and limit the compressor's frequency during operation. However, as the compressor ages, wear occurs in internal rotating parts and other areas. If the compressor operates at excessively high frequencies, this wear will further exacerbate the wear, leading to compressor malfunction and significantly shortening its lifespan.

The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0055] This application provides a compressor frequency adjustment method, apparatus, air conditioning equipment, and storage medium, which will be described in detail below.

[0056] The compressor frequency adjustment method in this embodiment of the invention is applied to a compressor frequency adjustment device, which is installed in an air conditioning unit. The air conditioning unit is provided with one or more processors, a memory, and one or more application programs, wherein one or more application programs are stored in the memory and configured to be executed by the processor to implement the compressor frequency adjustment method. The air conditioning unit can be an air conditioner or a compressor control device.

[0057] In practical applications, the compressor frequency adjustment method can also be applied to servers. For example, the server obtains the ambient temperature corresponding to the compressor and the abrasive data of the abrasive particles in the compressor lubricating oil, wherein the abrasive data includes abrasive particle size and / or abrasive particle concentration; according to the inclusion relationship between the abrasive data and a preset data range, the frequency adjustment parameter corresponding to the abrasive data is obtained; according to the ambient temperature, the frequency threshold of the compressor is determined, and the frequency threshold is adjusted according to the frequency adjustment parameter.

[0058] like Figure 1 As shown, Figure 1 This is a schematic diagram of a compressor frequency adjustment method according to an embodiment of this application. The compressor frequency adjustment scenario in this embodiment includes an air conditioning device 100 (the air conditioning device 100 integrates a compressor frequency adjustment device). The air conditioning device 100 runs a computer-readable storage medium corresponding to compressor frequency adjustment to perform the compressor frequency adjustment steps.

[0059] Understandable, Figure 1The air conditioning equipment in the scenario of the compressor frequency adjustment method shown, or the devices included in the air conditioning equipment, do not constitute a limitation on the embodiments of the present invention. That is, the number or type of equipment included in the scenario of the compressor frequency adjustment method, or the number or type of devices included in each equipment, do not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be considered as equivalent substitutions or derivatives of the technical solutions claimed in the embodiments of the present invention.

[0060] In this embodiment of the invention, the air conditioning device 100 is mainly used for: obtaining the ambient temperature corresponding to the compressor, and abrasive data of abrasive particles in the compressor lubricating oil, wherein the abrasive data includes abrasive particle size and / or abrasive particle concentration; obtaining frequency adjustment parameters corresponding to the abrasive data based on the inclusion relationship between the abrasive data and a preset data range; determining the frequency threshold of the compressor based on the ambient temperature, and adjusting the frequency threshold based on the frequency adjustment parameters.

[0061] Those skilled in the art will understand that Figure 1 The application environment shown is merely one application scenario of the solution in this application and does not constitute a limitation on the application scenario of the solution in this application. Other application environments may include those that are more specific to this application. Figure 1 The number of more or fewer air conditioning units shown, or the network connection relationship of the air conditioning units, for example Figure 1 Only one air conditioning device is shown in the diagram. It is understood that the scenario of the compressor frequency adjustment method may also include one or more other air conditioning devices, which are not specifically limited here. The air conditioning device 100 may also include a memory for storing data, such as storing image information acquired by shooting.

[0062] Furthermore, in the scenario of the compressor frequency adjustment method of this application, the air conditioning device 100 can be equipped with a display device, or the air conditioning device 100 can be connected to an external display device 200 without a display device. The display device 200 is used to output the result of the compressor frequency adjustment method executed in the air conditioning device. The air conditioning device 100 can access the background database 300 (the background database can be in the local storage of the air conditioning device, or it can be located in the cloud). The background database 300 stores information related to compressor frequency adjustment, such as compressor frequency thresholds or pre-set mapping tables.

[0063] It should be noted that, Figure 1 The schematic diagram of the compressor frequency adjustment method shown is merely an example. The scenario of the compressor frequency adjustment method described in this embodiment of the invention is intended to more clearly illustrate the technical solution of this embodiment and does not constitute a limitation on the technical solution provided by this embodiment of the invention.

[0064] Based on the scenario described above regarding the compressor frequency adjustment method, an embodiment of the compressor frequency adjustment method is proposed.

[0065] like Figure 2 As shown, Figure 2 This is a schematic flowchart of an embodiment of the compressor frequency adjustment method in this application, which includes steps S201-S203:

[0066] S201. Obtain the ambient temperature corresponding to the compressor and the abrasive data of the abrasive particles in the compressor lubricating oil, wherein the abrasive data includes abrasive particle size and / or abrasive particle concentration.

[0067] The ambient temperature corresponding to the compressor, that is, the ambient temperature corresponding to the compressor's operating condition, can be understood to be the outdoor ambient temperature, the temperature difference between the indoor and outdoor ambient temperatures, the compressor refrigerant temperature, etc., and can be designed according to different usage scenarios of the compressor.

[0068] Specifically, in this embodiment of the application, the ambient temperature is the outdoor ambient temperature. It can be understood that the ambient temperature can be collected by a temperature sensor. In this embodiment of the application, the outdoor ambient temperature is collected by at least one temperature sensor installed in the environment corresponding to the compressor installation environment, and the ambient temperature data collected by the temperature sensor is sent to the air conditioning equipment.

[0069] The abrasive particles, specifically those generated by compressor wear, are important information carriers of the wear condition of rotating components. Most of them are present in the compressor lubricating oil. The abrasive particle size refers to the size data of the abrasive particles in the compressor lubricating oil, which can specifically include abrasive particle diameter, abrasive particle radius, abrasive particle surface area, etc., but this application does not impose specific limitations on these parameters. The abrasive particle concentration refers to the concentration data of the abrasive particles in the compressor lubricating oil corresponding to the concentration of the lubricating oil.

[0070] It is understandable that the wear data can be collected using a capacitive sensor. Capacitive sensors are frequently used in oil monitoring due to their simple structure, high integration, and high sensitivity. Online monitoring of wear particles in oil (compressor lubricating oil) not only allows for understanding the health status of the oil system but also enables the diagnosis and evaluation of the wear condition of rotating components through which the oil flows.

[0071] Specifically, in the embodiments of this application, the compressor frequency adjustment method is applied to an air conditioning device. When the air conditioning device detects that the compressor is working, it obtains the ambient temperature corresponding to the compressor installation environment, which is generally the outdoor ambient temperature, and obtains the abrasive data of the abrasive particles in the compressor lubricating oil according to the capacitive sensor.

[0072] S202. Based on the inclusion relationship between the abrasive data and the preset data range, obtain the frequency adjustment parameter corresponding to the abrasive data.

[0073] The inclusion relationship between the abrasive data and the preset data interval refers to the relationship that the abrasive data is included in any corresponding preset data interval. In other words, it can be understood that the preset data interval may correspond to different frequency adjustment parameters with different preset level intervals. It can also be understood that the preset data interval can be divided into different level intervals according to the parameter span of the frequency adjustment parameters corresponding to different abrasive data. For example, if the parameter difference between frequency adjustment parameter 1 corresponding to abrasive data 1 and frequency adjustment parameter 2 corresponding to abrasive data 2 is relatively large, then abrasive data 1 can be used as a node of preset data interval 1, and abrasive data 2 can be used as a node of preset data interval 2.

[0074] Specifically, there are many ways to implement the scheme for determining the frequency adjustment parameters, and this application does not impose any specific limitations. For example:

[0075] One feasible implementation scheme is that the abrasive data includes abrasive size, the preset data range includes at least one preset abrasive size range, and if the abrasive size belongs to one of the target preset abrasive size ranges, then the frequency adjustment parameter corresponding to the target preset abrasive size range is obtained.

[0076] In the second feasible implementation scheme, the abrasive data includes abrasive concentration, and the preset data range includes at least one preset abrasive concentration range. If the abrasive size belongs to one of the target preset abrasive concentration ranges, then the frequency adjustment parameter corresponding to the target preset abrasive concentration range is obtained.

[0077] In the feasible implementation scheme 3, the abrasive data includes abrasive size and abrasive concentration, the preset data range includes at least one preset abrasive size range and at least one preset abrasive concentration range, and the corresponding frequency adjustment parameters are determined according to the preset target preset abrasive concentration range to which the abrasive size belongs and the target preset abrasive size range to which the abrasive size belongs.

[0078] S203. Determine the frequency threshold of the compressor based on the ambient temperature, and adjust the frequency threshold according to the frequency adjustment parameters.

[0079] The compressor frequency threshold is a preset frequency threshold for different ambient temperatures. For example, it can be understood that the frequency threshold can be obtained by looking up a preset mapping table based on the ambient temperature of the compressor.

[0080] Specifically, in the implementation scheme of this application, adjusting the frequency threshold specifically includes the following steps:

[0081] (1) Find the frequency threshold corresponding to the ambient temperature according to the preset mapping table of ambient temperature and frequency;

[0082] (2) The frequency adjustment parameter is fused with the frequency threshold to obtain the adjusted frequency threshold.

[0083] (3) Monitor the frequency of the compressor according to the adjusted frequency threshold.

[0084] In this embodiment of the application, the frequency threshold is the upper limit of the compressor frequency. After obtaining the compressor frequency threshold, the air conditioning device merges the frequency adjustment parameter with the frequency threshold to obtain the merged and adjusted frequency threshold, and limits the compressor's working frequency based on the adjusted frequency threshold.

[0085] It is understood that fusing the frequency adjustment parameter with the frequency threshold can be achieved by subtracting the frequency adjustment parameter from the frequency threshold, or by multiplying the frequency adjustment parameter with the frequency threshold if the frequency adjustment parameter is an adjustment coefficient. The specific fusion scheme can be designed according to the design type of the frequency adjustment parameter, and this application does not impose any specific limitations.

[0086] Specifically, in the implementation scheme of this application, when the capacitive sensor detects a large number of abrasive particles in the oil and the abrasive particles have a large diameter, it is determined that the compressor is severely worn, thereby limiting the upper limit frequency of compressor operation, reducing the number of revolutions the compressor makes in the same operating time, and increasing the service life of the air conditioner.

[0087] Further, see Figure 3 , Figure 3 This is a flowchart illustrating one embodiment of the compressor frequency adjustment method for determining frequency adjustment parameters in this application, including steps S301-S302:

[0088] S301. If the abrasive grain size is within a preset abrasive grain size range, then obtain the preset abrasive grain concentration range corresponding to the preset abrasive grain size range.

[0089] Specifically, in the embodiments of this application, the abrasive data includes abrasive size and abrasive concentration. After obtaining the abrasive concentration and abrasive size data, the air conditioning device obtains a preset abrasive size range corresponding to the abrasive size, and performs data matching between the abrasive size and each preset abrasive size range to determine a first preset abrasive size range corresponding to the abrasive size. If the abrasive size is within the first preset abrasive size range, then a first preset abrasive concentration range corresponding to the first abrasive size range is determined. It can be understood that the first abrasive size range can be associated with and stored with the first preset abrasive concentration range.

[0090] S302. If the abrasive concentration is included in the preset abrasive concentration range, then obtain the frequency adjustment parameter corresponding to the preset abrasive size range.

[0091] Furthermore, after obtaining the first preset abrasive particle concentration range corresponding to the first abrasive particle size range, the air conditioning device performs data matching between the abrasive particle concentration and the first preset abrasive particle concentration range to determine whether the abrasive particle concentration belongs to the first preset abrasive particle concentration range. Then, based on the preset correlation or mapping relationship, it determines the frequency adjustment parameter corresponding to the first preset abrasive particle size range.

[0092] It is understood that in some other embodiments of this application, the frequency adjustment parameter may also be associated with and stored in relation to the first preset abrasive particle concentration range. That is, the air conditioning device determines the frequency adjustment parameter corresponding to the first preset abrasive particle concentration range according to the preset association or mapping relationship.

[0093] Furthermore, in some other embodiments of this application, after obtaining the abrasive concentration and abrasive size data, the air conditioning device may first obtain the preset abrasive concentration range corresponding to the abrasive concentration, and match the abrasive concentration with each preset abrasive concentration range to determine the first preset abrasive concentration range corresponding to the abrasive concentration. If the abrasive concentration is within the first preset abrasive concentration range, then the first preset abrasive size range corresponding to the first abrasive concentration is determined. Specifically, this application does not specifically limit the comparison method of abrasive concentration and abrasive size.

[0094] In other embodiments of this application, after obtaining the first preset abrasive particle concentration range corresponding to the first abrasive particle size range, the air conditioning device performs data matching between the abrasive particle concentration and the first preset abrasive particle concentration range to determine whether the abrasive particle concentration belongs to the first preset abrasive particle concentration range. If the abrasive particle concentration is not included in the first preset abrasive particle concentration range, the size relationship between the abrasive particle concentration and the endpoints of the first preset abrasive particle concentration range is determined. It can be understood that the endpoints of the range include a first endpoint and a second endpoint greater than the first endpoint. Between the first endpoint and the second endpoint, the data of the first endpoint and the second endpoint form an interval. If the abrasive particle concentration is less than the abrasive particle concentration threshold corresponding to the first endpoint, the second preset abrasive particle concentration range corresponding to the abrasive particle concentration is determined. If the second endpoint of the second preset abrasive particle concentration range is less than the first endpoint corresponding to the first preset abrasive particle concentration range, the second preset abrasive particle size range corresponding to the second preset abrasive particle concentration range is obtained, and the frequency adjustment parameter corresponding to the second preset abrasive particle size range is determined. If the first endpoint of the second preset abrasive concentration range is greater than the second endpoint of the first preset abrasive concentration range, then obtain the frequency adjustment parameter correction value (greater than 1) corresponding to the second preset abrasive concentration range, and correct the frequency adjustment parameter corresponding to the first preset abrasive size range according to the correction value.

[0095] Further, see Figure 4 , Figure 4 This is a flowchart illustrating another embodiment of the compressor frequency adjustment method of this application, including steps S401-S405:

[0096] S401. Obtain the ambient temperature corresponding to the compressor and the abrasive data of the abrasive particles in the compressor lubricating oil, wherein the abrasive data includes abrasive particle size and / or abrasive particle concentration;

[0097] S402. Based on the inclusion relationship between the abrasive data and the preset data range, obtain the frequency adjustment parameter corresponding to the abrasive data;

[0098] S403. Determine the frequency threshold of the compressor based on the ambient temperature, and adjust the frequency threshold according to the frequency adjustment parameters.

[0099] The implementation schemes for steps S401-S403 are described in any of the implementation schemes corresponding to S301-S303 above.

[0100] S404. If the ambient temperature is greater than the preset temperature threshold, the flow adjustment parameters of the compressor are determined based on the data difference between the abrasive data and the corresponding preset abrasive data threshold.

[0101] The flow adjustment parameters, namely the flow adjustment parameters that adjust the flow rate of the compressor, include, for example, the opening degree of the electronic expansion valve, the frequency of compressor rise and fall, etc.

[0102] It is understood that the ambient temperature is a real-time monitored value. Specifically, after acquiring the ambient temperature, the air conditioning equipment compares the ambient temperature with a preset temperature threshold. If the ambient temperature is greater than the preset temperature threshold, the difference between the abrasive data and the corresponding preset abrasive data threshold is calculated. Specifically, this can be calculating the difference between the abrasive size and a preset abrasive size threshold, or calculating the difference between the abrasive concentration and a preset abrasive concentration threshold. Alternatively, both the difference between the abrasive size and a preset abrasive size threshold and the difference between the abrasive concentration and a preset abrasive concentration threshold can be calculated simultaneously. That is, it is understood that the data difference can include a concentration difference and / or a size difference.

[0103] Furthermore, the air conditioning equipment determines the compressor adjustment parameters based on the difference data. Specifically, for example, the adjustment parameters are determined according to a preset mapping table corresponding to the difference and the adjustment parameters.

[0104] Specifically, in the embodiments of this application, the implementation scheme for determining the compressor flow adjustment parameters based on ambient temperature includes:

[0105] (1) If the ambient temperature is greater than the preset temperature threshold, calculate the concentration difference between the abrasive concentration and the preset abrasive concentration threshold.

[0106] (2) The concentration difference and the expansion valve parameters of the compressor are combined to obtain the expansion valve opening degree corresponding to the compressor, wherein the expansion valve opening degree is the flow adjustment parameter.

[0107] It is understood that the expansion valve parameters of the compressor are the current opening degree of the compressor's expansion valve.

[0108] Specifically, in the embodiments of this application, the concentration difference value and the expansion valve parameter of the compressor are fused together. For example, the concentration difference value and the expansion valve parameter of the compressor are added together, or the expansion valve adjustment coefficient corresponding to the concentration difference value is determined, and the adjustment coefficient and the expansion valve parameter of the compressor are multiplied together, etc.

[0109] S405. Adjust the compressor flow rate according to the flow rate adjustment parameters.

[0110] It is understandable that increased temperature leads to accelerated wear. If the ambient temperature exceeds a preset temperature threshold, further adjusting the compressor's flow parameters while simultaneously adjusting the upper limit frequency can reduce compressor wear. After setting the flow adjustment parameters, the air conditioning unit adjusts the compressor flow rate, i.e., adjusts the opening of the electronic expansion valve, based on these parameters.

[0111] Further, see Figure 5 , Figure 5 This is a flowchart illustrating one embodiment of the compressor frequency adjustment method for determining frequency adjustment parameters, as described in this application, including steps S501-S504:

[0112] S501. Obtain the ambient temperature corresponding to the compressor, as well as the initial abrasive particle size and initial abrasive particle concentration in the compressor lubricating oil.

[0113] The initial abrasive temperature and initial abrasive size refer to the abrasive temperature and abrasive size detected by the capacitive sensor.

[0114] S502. Based on the preset mapping table corresponding to temperature and abrasive parameters, determine the abrasive size compensation amount and abrasive concentration compensation amount corresponding to the ambient temperature.

[0115] The abrasive size compensation amount refers to the abrasive size data that corrects the initial abrasive size, such as the abrasive size to be corrected, the abrasive size coefficient for correcting the abrasive size, etc.

[0116] The abrasive concentration compensation amount refers to the abrasive concentration data that corrects the initial abrasive concentration, such as the abrasive concentration to be corrected, the abrasive concentration coefficient for correcting the abrasive concentration, etc.

[0117] It is understandable that the preset mapping table corresponding to temperature and abrasive parameters can be set according to the implementation data to establish the corresponding mapping relationship.

[0118] S503. Determine the abrasive size of the abrasive particles in the compressor lubricating oil based on the abrasive size compensation amount and the initial abrasive size.

[0119] It is understood that the compensation based on the abrasive size can be determined according to the nature of different abrasive size compensation amounts. This application does not make specific limitations. For example, when the abrasive size compensation amount is the abrasive size to be corrected, the abrasive size compensation amount is added to or subtracted from the initial abrasive size to determine the abrasive size of the abrasive particles in the compressor lubricating oil.

[0120] S504. Determine the abrasive concentration in the compressor lubricating oil based on the abrasive concentration compensation amount and the initial abrasive concentration.

[0121] It is understood that the compensation based on the abrasive concentration can be determined according to the nature of different abrasive concentration compensation amounts. This application does not make specific limitations. For example, when the abrasive concentration compensation amount is the abrasive concentration to be corrected, the abrasive concentration compensation amount is added to or subtracted from the initial abrasive concentration to determine the abrasive concentration of the abrasive particles in the compressor lubricating oil.

[0122] Understandably, for each type of compressor, the ambient temperature will affect the capacity of its built-in capacitance sensor. That is, different ambient temperatures will affect the detection accuracy of the capacitance sensor. In order to eliminate the influence of temperature on the capacitance measured by the capacitance sensor, a corresponding capacitance sensor temperature compensation method is designed. That is, by determining the abrasive size compensation amount and abrasive concentration compensation amount corresponding to the ambient temperature, the detected abrasive size and abrasive concentration are compensated to ensure the accuracy of abrasive data.

[0123] Specifically, in some other embodiments of this application, after determining the abrasive size compensation amount and the abrasive concentration compensation amount corresponding to the ambient temperature based on a preset mapping table corresponding to temperature and abrasive parameters, the method includes:

[0124] (1) Statistically measure the total working time of the detection device for detecting the initial abrasive particle size and initial abrasive particle concentration.

[0125] (2) Based on the preset mapping table corresponding to the duration and correction coefficient, determine the abrasive size correction coefficient and abrasive concentration correction coefficient corresponding to the total working time.

[0126] (3) The abrasive size compensation amount is corrected according to the abrasive size correction coefficient, and the abrasive concentration compensation amount is corrected according to the abrasive concentration correction coefficient.

[0127] (4) Determine the abrasive size of the abrasive particles in the compressor lubricating oil based on the corrected abrasive size compensation amount and the initial abrasive size.

[0128] (5) Determine the abrasive concentration in the compressor lubricating oil based on the corrected abrasive concentration compensation amount and the initial abrasive concentration.

[0129] In the embodiments of this application, the abrasive size correction coefficient and the abrasive concentration correction coefficient are used to correct the abrasive size compensation amount and the abrasive concentration compensation amount, or to compensate for the increase or decrease.

[0130] It is understandable that the sensitivity of the sensor used to detect the initial abrasive size and initial abrasive concentration will decrease as the usage time increases. By determining the abrasive size correction coefficient and the abrasive concentration correction coefficient based on the total working time of the detection device, the abrasive concentration compensation amount and the abrasive size compensation amount can be further corrected to ensure the accuracy of the final abrasive size and abrasive concentration, thereby improving the compressor frequency adjustment accuracy.

[0131] Further, see Figure 6 , Figure 6 This is a flowchart illustrating one embodiment of the compressor frequency adjustment method for determining frequency adjustment parameters, as described in this application, including steps S601-S606:

[0132] S601. Obtain the ambient temperature corresponding to the compressor and the abrasive data of the abrasive particles in the compressor lubricating oil, wherein the abrasive data includes abrasive particle size and / or abrasive particle concentration.

[0133] S602. Based on the inclusion relationship between the abrasive data and the preset data range, obtain the frequency adjustment parameter corresponding to the abrasive data.

[0134] The implementation schemes for steps S601-S602 can be found in any of the above implementation schemes.

[0135] S603. Query historical frequency adjustment records. For each historical frequency adjustment record, calculate the frequency difference between the adjusted frequency threshold and the original frequency threshold.

[0136] Specifically, after adjusting the frequency threshold according to the frequency adjustment parameters, the air conditioning equipment acquires a preset number of historical frequency adjustment records, such as five historical frequency adjustment records or twenty historical frequency adjustment records. That is, the historical frequency adjustment records include at least one set of historical frequency adjustment data, and one set of historical frequency adjustment data includes the frequency threshold before adjustment and the frequency threshold after adjustment. It can be understood that the historical frequency adjustment records are historical frequency adjustment techniques similar to the ambient temperature and the abrasive data. Similarity means that the error does not exceed a preset threshold (which can be designed according to accuracy requirements). Further, the frequency difference between the adjusted frequency threshold and the frequency threshold before adjustment is calculated, and the frequency difference is compared with a preset frequency difference threshold.

[0137] S604. If the frequency difference is greater than the preset threshold more than half the time, then the preset mapping table corresponding to temperature and frequency is updated according to the adjusted frequency threshold.

[0138] Furthermore, after comparing multiple frequency differences with a preset frequency difference threshold, if the frequency difference is greater than the preset frequency difference threshold, it indicates that the frequency threshold adjustment difference is large. If the number of frequency differences greater than the preset threshold exceeds half of the total number of frequency differences, the preset mapping table corresponding to temperature and frequency is updated. Specifically, the average value of the adjusted frequency thresholds in the historical frequency adjustment records can be calculated, and the averaged frequency thresholds can be updated to the compressor ambient temperature and the corresponding frequency thresholds in the preset mapping table for use when the preset mapping table is adjusted for frequency thresholds in the future.

[0139] S605. According to the preset mapping table of temperature and frequency, find the frequency threshold corresponding to the ambient temperature.

[0140] S606. The frequency adjustment parameter is fused with the frequency threshold to obtain the adjusted frequency threshold.

[0141] The implementation schemes for steps S605-S606 can be found in any of the above implementation schemes.

By monitoring the abrasive data of abrasive particles in the compressor lubricating oil and adjusting the compressor wear information fed back by the abrasive data, the compressor frequency threshold is adjusted at different ambient temperatures. This allows the compressor frequency threshold to be adaptively adjusted to correspond to compressor wear information and different operating conditions, thereby avoiding unreasonable compressor frequency thresholds, reducing compressor wear, significantly extending compressor lifespan, and ultimately extending the lifespan of the air conditioner.
