Description

Technical Field

[0001] The present disclosure relates to the field of refrigerant technology, and in particular to a refrigerant charging method, device, storage medium and computer program product. Background Art

[0002] Refrigerant, also known as refrigerant, is a working fluid used to transfer heat energy and produce a refrigeration effect in an air-conditioning system. It achieves heat transfer through heat absorption and evaporation and heat release and condensation. For example, the refrigerant absorbs heat from the indoor air and evaporates. The refrigerant changes from liquid to gas, causing the indoor air temperature to drop, achieving the effect of cooling the room. The high-temperature and high-pressure gaseous refrigerant in the room flows into the outdoor unit, and the refrigerant condenses from gas to liquid, releasing heat to the outdoor air, achieving the effect of warming the room.

[0003] In the related art, in the field of refrigerant, refrigerant is filled into the outdoor unit of the air conditioner.

[0048] The technical solution provided by the embodiments of the present disclosure may have the following beneficial effects:

[0049] Since there may be refrigerant leakage and refrigerant residue in the process of charging the refrigerant by the charging machine, there will be a deviation between the first charging amount provided by the charging machine to the air-conditioning outdoor unit and the actual second charging amount. Therefore, the charging machine can be controlled to increase the refrigerant charging amount for the air-conditioning outdoor unit from the first charging amount to the third charging amount next time. After eliminating the deviation caused by refrigerant leakage or refrigerant residue on the basis of the third charging amount, the charging machine will still provide the air-conditioning outdoor unit with a refrigerant charging amount close to the first charging amount, thereby realizing automatic calibration of the refrigerant charging amount actually charged to the air-conditioning outdoor unit to the first charging amount.

[0050] Firstly, it does not require manual calibration, and the charging machine can dynamically adjust the third charging amount charged into the air conditioner according to the deviation, thereby avoiding the defects of low efficiency and low precision brought by manual calibration; secondly, for the same type of air-conditioning outdoor units, the charging amount will be adaptively adjusted to the third charging amount according to the deviation, even if there is refrigerant leakage or refrigerant residue, the final amount of refrigerant charged into the air-conditioning outdoor unit will be close to the first charging amount, so that the refrigerant amount in each air-conditioning outdoor unit of the same type tends to be consistent, thereby ensuring the consistency of the performance of each air-conditioning outdoor unit of the same type.

[0066] 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.

[0067] The implementations described in some of the following embodiments of the present disclosure do not represent all implementations 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 attached claims. It should be noted that all actions of obtaining signals, information or data in the present disclosure are carried out in compliance with the corresponding data protection laws and policies of the country of residence and with the authorization given by the owner of the corresponding device.

[0068] Figure 1 is a flow chart of a refrigerant charging method according to an exemplary embodiment. Figure 1 As shown, the refrigerant charging method can be used in a charging machine, including the following steps.

[0069] In step S10, a first charge amount is obtained. The first charge amount is the refrigerant charge amount provided by the charge machine to the air conditioner outdoor unit. Different types of air conditioner outdoor units have different first charge amounts. The charge machine can scan the identification code of the air conditioner outdoor unit and query the first charge amount corresponding to the identification code, thereby providing different first charge amounts for different types of air conditioner outdoor units. The identification code can be the product serial number (SN) of the air conditioner outdoor unit, which is used to uniquely identify the air conditioner outdoor unit.

[0070] The charging machine is a device that charges the refrigerant into the outdoor unit of the air conditioner. The charging machine will first recover the refrigerant, then purify the refrigerant to remove impurities in the refrigerant; then vacuum the refrigerant to extract the air in the refrigerant to ensure that there is no air in the refrigerant; finally, the refrigerant will be charged into the outdoor unit of the air conditioner.

[0071] When cooling or heating the room, an air conditioning system is needed to cool or heat the room. The air conditioning system includes an indoor unit and an outdoor unit. The indoor unit can also be called an indoor unit, which is usually installed indoors. It is responsible for the circulation and temperature regulation of indoor air. The evaporator of the indoor unit absorbs indoor heat, causing the refrigerant to evaporate, thereby reducing the indoor temperature. The outdoor unit is also called an outdoor unit, which is usually installed outdoors. It is responsible for releasing the heat absorbed by the indoor unit and compressing the refrigerant. The condenser of the outdoor unit condenses the gaseous refrigerant into liquid and releases heat to the outdoors. The outdoor unit also includes a compressor, which is used to compress the refrigerant, increase the pressure and temperature of the refrigerant, and provide power for the circulation of the refrigerant.

[0072] The refrigerant may be at least one of ammonia (NH3), freons (CFCs), hydrocarbons (HCFCs) and hydrofluorocarbons (HFCs).

[0073] In step S20, a second charge amount is obtained. The second charge amount is the actual refrigerant charge amount that the charge machine charges into the air conditioner outdoor unit. Although the charge machine provides the air conditioner outdoor unit with the first charge amount of refrigerant, the charge machine may leak refrigerant during the process of charging the refrigerant into the air conditioner outdoor unit, and some refrigerant may be leaked and adhere to the delivery pipeline of the charge machine, resulting in the second charge amount actually charged by the charge machine to the air conditioner outdoor unit being less than the first charge amount provided by the charge machine.

[0074] For example, taking the first filling amount as 700g and the second filling amount as 695g, after the charging machine scans the identification code of the air-conditioning outdoor unit, it determines that the refrigerant filling amount required by the air-conditioning outdoor unit is 700g, and it will provide 700g of refrigerant filling amount for the air-conditioning outdoor unit; however, in the process of charging the refrigerant, there may be refrigerant leakage or refrigerant residue, resulting in the actual refrigerant filling amount of 695g charged to the air-conditioning outdoor unit by the charging machine.

[0075] In step S30, if there is a deviation between the first filling amount and the second filling amount, the first filling amount is adjusted to a third filling amount according to the deviation. Optionally, if there is a deviation between the first filling amount and the second filling amount, or the deviation is greater than a preset deviation, the first filling amount is adjusted to the third filling amount according to the deviation.

[0076] The third charge amount is greater than the first charge amount, the first charge amount is greater than the second charge amount, and the deviation between the third charge amount and the first charge amount is equal to the deviation between the first charge amount and the second charge amount. It can be understood that the deviation between the third charge amount and the first charge amount, and the deviation between the first charge amount and the second charge amount are both the refrigerant charge amounts leaked or remaining in the charging machine during the process of the charging machine charging the refrigerant into the air conditioner outdoor unit.

[0077] For example, the air conditioner outdoor unit requires a first filling amount of 700g, and the charging machine provides the first filling amount of 700g for the air conditioner outdoor unit; however, during the process of charging the refrigerant, there may be refrigerant leakage or refrigerant residue, resulting in the second filling amount actually filled by the charging machine into the air conditioner outdoor unit being 695g, then there will be a refrigerant amount deviation of 5g between the first filling amount and the second filling amount; the next time the charging machine provides refrigerant to the same type of air conditioner outdoor unit, it will provide the air conditioner outdoor unit with a third filling amount of 705g based on the 5g deviation, even if there is a refrigerant leakage or refrigerant residue of 5g, the refrigerant filling amount actually filled by the charging machine for the air conditioner outdoor unit will reach 700g, thereby meeting the refrigerant amount requirement of the air conditioner outdoor unit.

[0078] It is understandable that for each air conditioner, the charging machine will determine the deviation between the first charging amount and the second charging amount charged to the previous air conditioner by the charging machine, and then according to the deviation, the charging amount provided to the next air conditioner will be increased from the first charging amount to the third charging amount. In this way, the refrigerant charging amount charged to the next air conditioner can be adaptively adjusted according to the refrigerant charging deviation to the previous air conditioner.

[0079] In the related art, when there is a deviation between the amount of refrigerant provided by the charging machine to the air-conditioning outdoor unit and the amount of refrigerant actually charged into the air-conditioning outdoor unit by the charging machine, the staff will control the amount of refrigerant provided by the charging machine to the air-conditioning outdoor unit next time based on experience. This manual calibration method is not only inefficient, but also there will be accuracy deviations in controlling the amount of refrigerant provided by the charging machine based on manual experience. The accuracy of manual calibration is usually between 0.3% and 0.5%, and the accuracy of calibration cannot be guaranteed at every calibration.

[0080] In the embodiment of the present disclosure, when there is a deviation between the first filling amount provided by the charging machine to the air conditioner outdoor unit and the second filling amount actually charged into the air conditioner outdoor unit by the charging machine, the first filling amount will be increased to the third filling amount according to the deviation.

[0081] During this process, due to refrigerant leakage and refrigerant residue during the charging process of the charging machine, there is a deviation between the first charging amount provided by the charging machine to the air-conditioning outdoor unit and the actual second charging amount. Therefore, the charging machine can be controlled to increase the refrigerant charging amount for the air-conditioning outdoor unit from the first charging amount to the third charging amount next time. After eliminating the deviation caused by refrigerant leakage or refrigerant residue on the basis of the third charging amount, the charging machine will still provide the air-conditioning outdoor unit with a refrigerant charging amount close to the first charging amount.

[0082] Firstly, it does not require manual calibration, and the charging machine can dynamically adjust the third charging amount charged into the air conditioner according to the deviation, thereby avoiding the defects of low efficiency and low precision brought by manual calibration; secondly, for the same type of air-conditioning outdoor units, the charging amount will be adaptively adjusted to the third charging amount according to the deviation, even if there is refrigerant leakage or refrigerant residue, the final amount of refrigerant charged into the air-conditioning outdoor unit will be close to the first charging amount, so that the refrigerant amount in each air-conditioning outdoor unit of the same type tends to be consistent, thereby ensuring the consistency of the performance of each air-conditioning outdoor unit of the same type.

[0083] Figure 3 The present disclosure relates to a schematic diagram of obtaining an actual second filling amount filled by a filling machine into an air conditioner outdoor unit, which includes the following steps:

[0084] In step S40, a first weight of the air-conditioning outdoor unit before being charged with the first charging amount and a second weight of the air-conditioning outdoor unit after being charged with the first charging amount are obtained.

[0085] See also Figure 2 As shown, the production line for producing the air-conditioning outdoor unit includes an import conveyor belt and an export conveyor belt. The air-conditioning outdoor unit enters the production line through the import conveyor belt and is then output from the production line through two export conveyor belts. When the air-conditioning outdoor unit passes through the first weighing station, the amount of refrigerant in the refrigerant tank of the air-conditioning outdoor unit is weighed for the first time at the first weighing station. The amount of refrigerant weighed at the first weighing station is the first weight; the air-conditioning outdoor unit is then transferred from the first weighing station to the cache position upstream of the export conveyor belt. The upstream cache position is used to temporarily store the air-conditioning outdoor unit. The baffle blocks the air-conditioning outdoor unit at the upstream cache position. After the air-conditioning outdoor unit at the filling position is fully filled, the baffle releases the air-conditioning outdoor unit at the upstream cache position and transfers it to the filling position; when the air-conditioning outdoor unit passes through the first weighing station, the baffle releases the air-conditioning outdoor unit at the upstream cache position and transfers it to the filling position. When the outdoor unit is transferred to the filling position, the filling machines on each filling position fill the refrigerant into the refrigerant tank of the air-conditioning outdoor unit through the filling gun; there is still a baffle between the filling position and the downstream buffer position, and the baffle will release the air-conditioning outdoor unit on the filling position only after the air-conditioning outdoor unit on the filling position is completely filled, and the air-conditioning outdoor unit will be transferred to the downstream buffer position; the air-conditioning outdoor unit will then reach the second weighing station through the downstream buffer position, and the amount of refrigerant in the refrigerant tank of the air-conditioning outdoor unit will be weighed for the second time at the second weighing station, and the amount of refrigerant weighed at the second weighing station is the second weight.

[0086] Among them, at the first weighing station and the second weighing station, the refrigerant tank of the air-conditioning outdoor unit can be weighed by an electronic scale. The weighing accuracy of the electronic scale can reach 0.1g and the measuring range is 30Kg.

[0087] Among them, at the filling position, when the sensor on the filling machine detects that the filling machine is filling refrigerant into the refrigerant tank of the air-conditioning outdoor unit, the barcode scanning gun on the filling machine will bind the air-conditioning outdoor unit with the filling machine, instructing the filling machine to continue filling refrigerant into the air-conditioning outdoor unit.

[0088] The first weight is the weight of the refrigerant tank itself when the air-conditioning outdoor unit is weighed on the first weighing station before the refrigerant is injected into the refrigerant tank of the air-conditioning outdoor unit; the second weight is the weight of the refrigerant tank plus the refrigerant when the air-conditioning outdoor unit is weighed on the second weighing station after the refrigerant is injected into the refrigerant tank of the air-conditioning outdoor unit.

[0089] In step S50, the second filling amount is obtained according to the first weight and the second weight.

[0090] The first weight may be subtracted from the second weight to obtain a second filling amount actually filled into the air conditioner outdoor unit by the filling machine.

[0091] Through the above technical scheme, the first weight of the refrigerant tank before the air-conditioning outdoor unit is charged with the first filling amount and the second weight of the refrigerant tank after the air-conditioning outdoor unit is charged with the first filling amount can be calculated; subtracting the first weight from the second weight can obtain the actual second filling amount that the filling machine charges into the air-conditioning outdoor unit, which realizes the automatic calculation of the second filling amount.

[0092] Figure 4 is an exemplary solution involved in the above step S30, which is used to explain an exemplary solution for adjusting the first filling amount to the third filling amount, and includes the following steps:

[0093] In step S31 , when there is a deviation between the first filling amount and the second filling amount, a deviation value between the first filling amount and the second filling amount is determined.

[0094] The difference between the first filling amount and the second filling amount may be taken as the deviation value between the first filling amount and the second filling amount.

[0095] For example, if the first filling amount is 700 g and the second filling amount is 695 g, then the deviation between the first filling amount and the second filling amount is 5 g.

[0096] In step S32, the third filling amount is obtained according to the first filling amount and the deviation value.

[0097] A deviation value may be superimposed on the first filling amount to obtain a third filling amount, and the third filling amount is obtained on the basis of the first filling amount by taking into account the deviation value caused by factors such as refrigerant leakage and refrigerant residue.

[0098] In step S33, the first filling amount is adjusted to the third filling amount.

[0099] Optionally, if the charging machine provided the first charging amount to the air-conditioning outdoor unit last time, it will provide the third charging amount to the air-conditioning outdoor unit next time.

[0100] For example, the charging machine provided 700g of refrigerant to the air-conditioning outdoor unit A last time, and will provide 705g of refrigerant to the air-conditioning outdoor unit B next time. The air-conditioning outdoor unit A and the air-conditioning outdoor unit B are the same type of air-conditioning outdoor units.

[0101] Through the above technical scheme, the third filling amount can be obtained by adding the deviation value caused by factors such as refrigerant leakage and refrigerant residue during the previous filling of the filling machine on the basis of the first filling amount, so that the filling machine can provide the third filling amount of refrigerant to the air-conditioning outdoor unit next time. Even if there is a deviation value caused by refrigerant leakage and refrigerant residue, after subtracting the deviation value from the third filling amount, the filling machine will actually charge the air-conditioning outdoor unit with the first filling amount of refrigerant. In this way, except for the deviation of the refrigerant amount charged into the air-conditioning outdoor unit by the filling machine for the first time, the subsequent amount of refrigerant charged into the air-conditioning outdoor unit will be balanced around the first filling amount, thereby achieving the consistency of the refrigerant amount in each air-conditioning outdoor unit, and thus ensuring the consistency of the performance of each air-conditioning outdoor unit.

[0102] Figure 5 Another exemplary solution for correcting the first filling amount proposed by an exemplary embodiment of the present disclosure includes:

[0103] In the event of a deviation between the first filling amount and the second filling amount, the second filling amount is corrected to the first filling amount.

[0104] For example, if the first charging amount provided by the charging machine for the air-conditioning outdoor unit is 700g, but the second charging amount actually charged into the air-conditioning outdoor unit by the charging machine is 695g, it may mean that the charging flow of the charging machine is too large and the delivery pipe of the air-conditioning outdoor unit is too small, and the refrigerant provided by the charging machine is sprayed out from the interface of the air-conditioning outdoor unit, resulting in a 5g refrigerant leakage. At this time, the operating parameters of the charging machine itself can be corrected so that the first charging amount provided by the subsequent charging machine to the air-conditioning outdoor unit is equal to the second charging amount actually charged into the air-conditioning outdoor unit by the charging machine, thereby correcting the second charging amount to the first charging amount.

[0105] Optionally, see Figure 5 As shown, correcting the second filling amount to the first filling amount includes the following sub-steps:

[0106] Sub-step A1: when there is a deviation between the first filling amount and the second filling amount, determining abnormal operating parameters of the filling machine.

[0107] The operating parameters of the charging machine are the equipment parameters when the charging machine is running and / or the environmental parameters of the charging machine.

[0108] See also Figure 7As shown, the parameters of the charging machine include maintenance factors, charging machine parameters, environmental parameters, product parameters and process time series data. Among them, the maintenance factors include the sensor maintenance time on the charging machine, the charging machine maintenance time, the refrigerant arrival time of the refrigerant to the air conditioner outdoor unit, and the refrigerant model; the charging machine parameters include the charging time, the charging machine start time, the refrigerant density, the refrigerant temperature and the vacuum degree; the environmental parameters include the ambient temperature and atmospheric pressure of the charging machine; the product parameters include the refrigerant pipe volume (the thickness of the refrigerant pipe), the expansion valve opening, the refrigerant pipe shape and the product model; the process time series data includes the charging flow, the charging pressure curve, the charging speed curve and the valve opening curve during the charging process of the charging machine charging the refrigerant to the air conditioner outdoor unit.

[0109] Among the parameters of the above-mentioned charging machine, the sensor maintenance time (the sensor is a sensor on the charging machine used to sense whether the charging machine is charging refrigerant for the air conditioner outdoor unit), the charging machine maintenance time, the refrigerant arrival time of the refrigerant to the air conditioner outdoor unit, the refrigerant model, the charging machine start time, the atmospheric pressure and the refrigerant pipe volume are operating parameters that have no effect on the charging accuracy; the refrigerant density, the expansion valve opening, the refrigerant pipe shape and the valve opening curve are operating parameters that cannot be monitored; the charging time, the refrigerant temperature, the vacuum degree, the ambient temperature, the charging flow rate, the charging pressure curve and the charging speed curve are operating parameters that have an effect on the charging accuracy and can be monitored. Therefore, the embodiments of the present disclosure can monitor these operating parameters that have an effect on the charging accuracy and can be detected, and when these operating parameters are abnormal, these operating parameters are used as abnormal operating parameters.

[0110] Among them, the field is the operating parameters of "can", which means that this part of the operating parameters are the parameters that the charging machine can adjust by itself, and the field is the operating parameters of "TPM", which means that this part of the operating parameters are the parameters that need to be adjusted manually.

[0111] It is understandable that when there is a deviation between the first filling amount provided by the charging machine and the second filling amount actually filled into the air-conditioning outdoor unit, it means that the charging machine itself may have a fault. Therefore, each of the multiple operating parameters of the charging machine can be self-checked to determine whether each operating parameter is abnormal, so as to check the abnormal operating parameters and correct the abnormal operating parameters to normal operating parameters. After the operating parameters of the charging machine are normal, the second filling amount actually filled into the air-conditioning outdoor unit by the charging machine can reach the first filling amount required by the air-conditioning outdoor unit.

[0112] There are two ways to determine whether the operating parameters are abnormal:

[0113] In a first solution, when a deviation between the operating parameter of the filling machine and the historical operating parameter of the filling machine is greater than a first preset value, the operating parameter of the filling machine is used as the abnormal operating parameter.

[0114] The historical operating parameter of the charging machine may be an average value of a plurality of historical operating parameters of the charging machine.

[0115] When the deviation between the operating parameters of the filling machine and the historical operating parameters of the filling machine is greater than the first preset value, it means that the operating parameters of the filling machine are abnormal and do not conform to the changing pattern of the previous operating parameters. Therefore, the current operating parameters of the filling machine can be regarded as abnormal operating parameters.

[0116] For example, taking the filling flow rate as an example, when the filling flow rate of the filling machine is significantly lower or higher than the previous historical filling flow rate of the filling machine, it means that the current filling flow rate abnormality of the filling machine has caused a deviation between the first filling amount and the second filling amount. Therefore, the current filling flow rate of the filling machine can be regarded as an abnormal filling flow rate, so that the abnormal filling flow rate can be corrected in the subsequent process.

[0117] In the second scheme, when the deviation value between the operating parameters of the charging machine and the operating parameters of the target charging machine is greater than a second preset value, the operating parameters of the charging machine are used as the abnormal operating parameters, and the target charging machine is a charging machine of the same type as the charging machine.

[0118] The operating parameter of the target charging machine may be an average value of the operating parameters of a plurality of target charging machines.

[0119] When the deviation value between the operating parameters of the filling machine and the operating parameters of the target filling machine is greater than the second preset value, it means that the operating parameters of the filling machine are abnormal, and the changing pattern of the operating parameters is different from that of other target filling machines. Therefore, the current operating parameters of the filling machine can be regarded as abnormal operating parameters.

[0120] For example, taking the filling flow rate as an example of the operating parameter of the filling machine, when the filling flow rate of the filling machine is significantly lower or higher than the filling flow rates of other target filling machines, it means that the current filling flow rate abnormality has caused a deviation between the first filling amount and the second filling amount. Therefore, the current filling flow rate of the filling machine can be regarded as an abnormal filling flow rate, so that the abnormal filling flow rate can be corrected in the subsequent process.

[0121] Sub-step A2: correcting the abnormal operating parameters to normal operating parameters, so as to correct the second filling amount to the first filling amount.

[0122] Optionally, the historical operating parameters of the filling machine may be used as the current normal operating parameters of the filling machine, and the abnormal operating parameters of the filling machine may be replaced with the normal operating parameters.

[0123] Optionally, the operating parameters of the target charging machine may be used as normal operating parameters, and the abnormal operating parameters of the charging machine may be replaced with the normal operating parameters.

[0124] In some scenarios, when there is a deviation between the first charging amount provided by the charging machine to the air conditioner outdoor unit and the second charging amount actually charged by the charging machine to the air conditioner outdoor unit, multiple operating parameters of the charging machine can be self-checked, such as checking whether the refrigerant temperature, the vacuum degree of the charging machine, the charging time of the charging machine, the charging speed curve of the charging machine, the charging pressure curve of the charging machine, the charging flow of the charging machine, the ambient temperature and other operating parameters are abnormal. Among these operating parameters, if the charging time is less than the normal charging time, it may cause the charging machine to charge too little refrigerant to the air conditioner outdoor unit, thereby making the second charging amount less than the first charging amount. Therefore, the charging time can be adaptively controlled to increase to the normal charging time, so that the refrigerant amount charged by the charging machine to the air conditioner outdoor unit reaches the first charging amount.

[0125] In other scenarios, when there is a deviation between the first charging amount provided by the charging machine to the air conditioner outdoor unit and the second charging amount actually charged by the charging machine to the air conditioner outdoor unit, multiple operating parameters of the charging machine can be self-checked, such as checking whether the refrigerant temperature, the vacuum degree of the charging machine, the charging time of the charging machine, the charging speed curve of the charging machine, the charging pressure curve of the charging machine, the charging flow of the charging machine, the ambient temperature and other operating parameters are abnormal. Among these parameters, if the charging flow is greater than the normal charging flow, the charging machine will charge the refrigerant to the air conditioner outdoor unit too fast, and the refrigerant will be ejected from the pipe interface of the air conditioner outdoor unit. Therefore, the abnormal charging flow can be corrected to the normal charging flow to ensure that the charging machine operates at the normal charging flow and avoid the refrigerant leakage caused by excessive charging flow. On the one hand, it reduces the waste of refrigerant, and on the other hand, it can avoid the phenomenon of less refrigerant in the air conditioner outdoor unit caused by refrigerant leakage.

[0126] Optionally, see Figure 8 As shown, the embodiments of the present disclosure propose an automatic calibration model and a parameter optimization model.

[0127] When the preset parameters cannot be obtained, the following scheme is executed through the automatic calibration model: the first weight and the second weight are obtained, and the second filling amount actually filled by the charging machine into the air conditioner outdoor unit is obtained based on the first weight and the second weight; finally, when there is a deviation between the first filling amount provided by the charging machine and the second filling amount actually filled by the charging machine, the first filling amount is adjusted to the third filling amount according to the deviation.

[0128] When the preset parameters can be obtained, the following scheme is executed through the parameter optimization model: when there is a deviation between the first filling amount and the second filling amount, the abnormal operating parameters are corrected to the normal operating parameters to correct the second filling amount to the first filling amount.

[0129] The preset parameters are configuration parameters built into the third party. The third party may be the manufacturer that provides the charging machine. Then the preset parameters may be the operating parameters of the charging machine. If the third party opens the preset parameters, the parameter optimization model is used to obtain the operating parameters of the charging machine itself, and the abnormal operating parameters of the charging machine are corrected to the normal operating parameters, so that the second charging amount actually charged by the charging machine to the air-conditioning outdoor unit is corrected to the first charging amount required by the air-conditioning outdoor unit; if the third party does not open the preset parameters, the automatic calibration model is used to increase the charging amount provided by the charging machine to the air-conditioning outdoor unit from the first charging amount to the third charging amount. In this way, even if the amount of refrigerant corresponding to the deviation value is leaked on the basis of the third charging amount, the actual amount of refrigerant charged to the air-conditioning outdoor unit is close to the first charging amount.

[0130] Among them, see Figure 8 As shown, the intelligent diagnosis model of the charging machine can be used to determine whether the configuration parameters are open to a third party.

[0131] Among them, see Figure 8 As shown, no matter increasing the first filling amount to the third filling amount or correcting the second filling amount to the first filling amount, it is necessary for the filling machine to fill the refrigerant into the air-conditioning outdoor unit, and it is also necessary to weigh and test the weight of the refrigerant tank before and after the filling of the air-conditioning outdoor unit, and it is also necessary to conduct a commercial inspection test on the performance of the air-conditioning outdoor unit; finally, the data obtained from the weighing test and the commercial inspection test are transmitted to the abnormal recognition model, and the abnormal recognition model monitors these data in real time.

[0132] Through the above technical scheme, when there is a deviation between the first filling amount and the second filling amount, the first method can be adopted to eliminate the influence of the deviation by controlling the first filling amount to increase to the third filling amount, so that the actual filling amount of the air-conditioning outdoor unit reaches the first filling amount; the second method can also be adopted to correct the abnormal operating parameters of the charging machine to normal operating parameters to ensure that the charging machine operates in a normal operating state, thereby correcting the second filling amount to the first filling amount.

[0133] Through the first method, it is not necessary to calculate and monitor the operating parameters of the complex charging machine, so the calculation amount and processing amount are both small. It can eliminate the influence of the deviation between the first charging amount and the second charging amount on the basis of simplifying the calculation amount and processing amount, so that the actual charging amount of the charging machine to the air conditioner outdoor unit reaches the first charging amount; through the second method, although the calculation amount is more complicated, it will not increase the first charging amount to the third charging amount. It directly corrects the operating parameters of the charging machine itself to achieve the purpose of correcting the second charging amount to the first charging amount, thereby reducing the waste of refrigerant. The first method and the second method can be executed simultaneously or separately, and the present disclosure does not limit this.

[0134] Figure 6 The present disclosure relates to an overall framework diagram and a step flow chart for self-checking the operating parameters of a filling machine, which includes the following steps:

[0135] In step S60, when there is a deviation between a first charging amount provided by the charging machine to the air conditioner outdoor unit and a second charging amount actually charged by the charging machine to the air conditioner outdoor unit, it is determined whether the charging machine has a first type of abnormality.

[0136] The first type of abnormality is a diagnostic abnormality, which means that the charging machine can correct the abnormality by self-diagnosis.

[0137] A second type of abnormality is also included. The second type of abnormality is a notification type abnormality. The notification type abnormality means that the abnormality cannot be corrected by the self-diagnosis of the charging machine and needs to be repaired manually.

[0138] For example, if the operating parameters of the charging machine are abnormal, it is a first type of abnormality, and the second charging amount can be corrected to the first charging amount by correcting the abnormal operating parameters during the reorganization season; if the parts of the charging machine are damaged and the failure of the parts cannot be changed by adjusting the operating parameters, it is a second type of abnormality, and it is necessary to manually repair or replace the parts of the charging machine to correct the second charging amount to the first charging amount.

[0139] Optionally, when the charging machine has the second type of abnormality, a third prompt message will also be output, the third prompt message being used to indicate that a component of the charging machine is faulty and that the charging machine provides too little or too much charging for the air conditioner outdoor unit.

[0140] In step S70, when the first type of abnormality exists in the charging machine, it is determined whether abnormal operating parameters of the charging machine can be identified.

[0141] When the filling machine has the first type of abnormality, it indicates that there may be problems with the operating parameters inside the filling machine. In order to further locate whether the filling machine has abnormal operating parameters, it is also possible to determine whether it is possible to identify whether there are abnormal operating parameters among the multiple operating parameters of the filling machine.

[0142] Each of the multiple operating parameters of the charging machine may be checked, and each operating parameter may be compared with a normal operating parameter, thereby locating an abnormal operating parameter among the multiple operating parameters.

[0143] In step S80, when the abnormal operating parameters of the charging machine can be identified, it is determined whether the deviation between the abnormal operating parameters and the normal operating parameters of the charging machine is greater than a third preset value.

[0144] When the abnormal operating parameters of the filling machine can be identified, it indicates that the deviation between the first filling amount and the second filling amount is caused by the abnormal operating parameters of the filling machine. Therefore, it can be further determined whether the deviation value between the abnormal operating parameters and the normal operating parameters of the filling machine is less than the third preset value.

[0145] Among them, when identifying abnormal operating parameters of the filling machine, the operating parameters of the filling machine can be regarded as abnormal operating parameters when the deviation value between the operating parameters of the filling machine and the historical operating parameters of the filling machine is greater than a first preset value; or, when the deviation value between the operating parameters of the filling machine and the operating parameters of the target filling machine is greater than a second preset value, the operating parameters of the filling machine can be regarded as abnormal operating parameters.

[0146] Optionally, when there are no abnormal operating parameters among the multiple operating parameters of the charging machine, that is, when the abnormal operating parameters cannot be identified, it means that the deviation between the first filling amount and the second filling amount is not caused by the operating parameters of the charging machine, and a first prompt message can be output. The first prompt message is used to prompt that the charging machine has a fault, but it is not caused by the abnormal operating parameters of the charging machine.

[0147] In step S90, when the deviation value between the abnormal operation parameter and the normal operation parameter is less than the third preset value, the abnormal operation parameter is corrected to the normal operation parameter.

[0148] When the deviation value between the abnormal operating parameters and the normal operating parameters is less than the third preset value, it means that the deviation value between the abnormal operating parameters and the normal operating parameters of the charging machine is small, and the deviation value is within a reasonable range. Even if the abnormal operating parameters are corrected to normal operating parameters, the charging machine operates according to the normal operating parameters and it will not have a major impact on the charging machine or the air-conditioning outdoor unit. Therefore, the charging machine can be allowed to correct the abnormal operating parameters to normal operating parameters.

[0149] Optionally, when the deviation value between the abnormal operating parameter and the normal operating parameter is greater than or equal to a third preset value, a second prompt information is output; the second prompt information includes the normal operating parameter.

[0150] When the deviation value between the abnormal operating parameters and the normal operating parameters is greater than or equal to the third preset value, it means that the deviation value between the abnormal operating parameters and the normal operating parameters of the charging machine is large, and the deviation value is not within a reasonable range. The abnormal operating parameters are corrected to normal operating parameters. After the charging machine operates according to the normal operating parameters with large changes, it may have a greater impact on the charging machine or the air-conditioning outdoor unit, thereby greatly changing the amount of refrigerant filled into the air-conditioning outdoor unit. Therefore, the second prompt information can be output to show the recommended normal operating parameters to the staff, who will manually judge whether to control the charging machine to operate with the normal operating parameters with large changes.

[0151] For example, taking the filling flow rate as an operating parameter, when the difference between the current abnormal filling flow rate of the filling machine and the normal operating flow rate is 100g / sec, it means that the deviation between the abnormal filling flow rate and the normal filling flow rate is large. At this time, if the abnormal filling flow rate is increased to the normal filling flow rate, the filling speed of the filling machine to the air-conditioning outdoor unit will be greatly increased. If the normal filling flow rate is inaccurate data, it will cause a large-scale leakage of refrigerant at the interface of the air-conditioning outdoor unit. Therefore, a second prompt message can be output. The second prompt message recommends the normal operating flow rate, so that the staff can judge again whether the normal operating flow rate is reasonable data.

[0152] See also Fig. 9 As shown, the architecture diagram to which the refrigerant charging method is applied includes an application process architecture, a model data layer, and an assembly layer.

[0153] The application process architecture includes an interactive flow chart of anomaly recognition model, anomaly diagnosis model, parameter optimization model and self-calibration model.

[0154] The abnormality recognition model is used to identify whether the filling machine has a first type of abnormality or a second type of abnormality, and when the filling machine has a first type of abnormality, the first type of abnormality is sent to the abnormality diagnosis model; when the filling machine has a second type of abnormality, a third prompt message is output to indicate a component failure of the filling machine.

[0155] The abnormal diagnosis model determines whether the abnormal operating parameters of the filling machine can be identified in response to the first type of abnormality, and if the abnormal operating parameters of the filling machine can be identified, the abnormal operating parameters of the filling machine are sent to the parameter optimization model. If the abnormal operating parameters of the filling machine cannot be identified, the first prompt information is output to indicate that the filling machine is faulty and is not caused by abnormal operating parameters.

[0156] The parameter optimization model determines whether the deviation value between the abnormal operating parameters and the normal operating parameters is less than a third preset value based on the abnormal operating parameters. When the deviation value is less than the third preset value, the abnormal operating parameters are corrected to normal operating parameters. When the deviation value is greater than or equal to the third preset value, a second prompt message is output to indicate the normal operating parameters.

[0157] The self-calibration model is used to send the second filling amount of the filling machine to the filling machine after the abnormal diagnosis model identifies the abnormal operating parameters of the filling machine, so that the second filling amount can be corrected to the first filling amount later.

[0158] It is understandable that after receiving the first prompt information, the second prompt information and the third prompt information, the staff will re-modify the operating parameters of the filling machine or repair the filling machine. When the filling machine operates normally, the second filling amount can also be adjusted to the first filling amount.

[0159] The model data layer includes anomaly recognition model, association analysis model, anomaly diagnosis model, quality prediction model and parameter optimization model.

[0160] Among them, in addition to identifying the abnormal type of the charging machine, the abnormal identification model can also be used to obtain the identification code of the air-conditioning outdoor unit, and monitor and obtain the first charging amount required by the air-conditioning outdoor unit corresponding to the identification code, the operating parameters of the charging machine itself, etc. The abnormal identification model includes a CPK monitoring and early warning module, an element monitoring module and an abnormal detection module. The monitoring and early warning module is used to monitor the performance of the charging machine, the element monitoring module is used to monitor the operating parameters of the charging machine, and the abnormal detection is used to detect whether the abnormal type of the charging machine is the first type or the second type.

[0161] The association analysis model is used to compare and analyze the commercial inspection data of multiple air-conditioning outdoor units, analyze the air-conditioning outdoor units with poor performance, and can also be used to analyze the operating parameters of multiple charging machines, or analyze the correlation between the operating parameters of the charging machine and the historical operating parameters, so as to determine whether the operating parameters of the charging machine are abnormal operating parameters. For example, the association analysis model can analyze the correlation between the current charging speed curve of the charging machine and the normal charging speed curve, so as to determine whether the current charging speed curve of the charging machine is abnormal; the quality prediction model is used to compare the operating parameters of the air-conditioning outdoor unit with the normal operating parameters, so as to determine whether there are problems with the air-conditioning quality. The association analysis model includes a causal inference module, a cluster analysis module, and a variance analysis module. These three modules are combined to analyze the correlation between the operating parameters of the charging machine and the normal operating parameters.

[0162] The abnormal diagnosis model is used to determine whether an abnormal operating parameter can be determined from multiple operating parameters. The abnormal diagnosis module includes a knowledge graph module, a Markov decision module and a rule engine module. These three modules are combined to analyze whether an operating parameter is an abnormal operating parameter.

[0163] The quality prediction model is used to predict the quality of the air conditioner outdoor unit and the charging machine. The quality prediction model includes a machine learning module, a deep learning module, and a transfer learning module. These three modules are combined to establish a mapping relationship between the air conditioner outdoor unit and the air conditioner quality, and a mapping relationship between the charging machine and the charging machine quality.

[0164] The parameter optimization model is used to correct abnormal operating parameters to normal operating parameters. The parameter optimization module includes an evolutionary algorithm module, a heuristic optimization module, and a reinforcement learning module. These three modules are combined to correct abnormal operating parameters to normal operating parameters.

[0165] The equipment layer includes commodity inspection and charging machine. The charging machine is the equipment that charges the refrigerant into the air conditioner outdoor unit, and the commodity inspection is used to test the performance of the air conditioner outdoor unit.

[0166] Through the above technical scheme, on the first hand, when the abnormal type of the charging machine is the first type, and the abnormal operating parameters among the multiple operating parameters of the charging machine can be identified, and the deviation value between the abnormal operating parameters and the normal operating parameters is less than the third preset value, the abnormal operating parameters are corrected to the normal operating parameters. It can also be understood that when it is determined that the charging machine can determine the abnormal operating parameters and the charging machine changes the abnormal operating parameters to the normal operating parameters without causing a significant impact on the charging process, the charging machine automatically changes the abnormal operating parameters to the normal operating parameters. After the operating parameters of the charging machine become the normal operating parameters, the charging machine will charge the refrigerant into the air-conditioning outdoor unit with the normal operating parameters to avoid refrigerant leakage, insufficient refrigerant in the air-conditioning outdoor unit, etc.; on the second hand, when the deviation value between the abnormal operating parameters and the normal operating parameters is greater than or equal to the third preset value, the normal operating parameters are displayed to the staff, and it is manually decided whether to change the abnormal operating parameters to the normal operating parameters to avoid a substantial decrease or increase in the amount of refrigerant after the charging machine runs with normal operating parameters with large deviations.
