[0002] At present, when users use air conditioners, they lack the means to monitor refrigerant leakage and cannot intervene in advance. As a result, when the refrigerant leakage is large and affects the cooling or cooling effect of the air conditioner, it is not until the insufficient refrigerant of the air conditioner is discovered and remedial measures are taken, which causes complaints from users.

[0003] Related technology discloses a method for determining air conditioner refrigerant leakage, including: obtaining the detection concentration of a first gas sensor to obtain a first detection concentration, obtaining the detection concentration of a second gas sensor to obtain a second detection concentration; when the first detection concentration is greater than the second detection concentration and the second detection concentration is greater than a concentration threshold, issuing a first alarm message, the first alarm message being a prompt message indicating that the air conditioner has a refrigerant leakage.

[0037] In the embodiments of the present disclosure, smart home appliances refer to home appliances that are formed by introducing microprocessors, sensor technology, and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent perception, and intelligent application. The operation process of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage the smart home appliances.

[0038] In the disclosed embodiments, the terminal device refers to an electronic device with a wireless connection function. The terminal device can communicate with the above-mentioned smart home appliances by connecting to the Internet, or can communicate with the above-mentioned smart home appliances directly through Bluetooth, WiFi, etc. In some embodiments, the terminal device is, for example, a mobile device, a computer, or a vehicle-mounted device built into a hover car, or any combination thereof. Mobile devices may include, for example, mobile phones, smart home devices, wearable devices, smart mobile devices, virtual reality devices, etc., or any combination thereof, wherein wearable devices include, for example: smart watches, smart bracelets, pedometers, etc.

[0039] At present, when users use air conditioners, they lack monitoring means for refrigerant leakage and cannot intervene in refrigerant leakage in advance. Only when the refrigerant leakage is large and affects the refrigeration or cooling effect of the air conditioner, can the insufficient refrigerant of the air conditioner be discovered and remedial measures be taken, causing user complaints. The related art discloses a method for determining refrigerant leakage of an air conditioner, including: obtaining the detection concentration of a first gas sensor to obtain a first detection concentration, obtaining the detection concentration of a second gas sensor to obtain a second detection concentration; when the first detection concentration is greater than the second detection concentration and the second detection concentration is greater than the concentration threshold, a first alarm message is issued, and the first alarm message is a prompt message indicating that the air conditioner has a refrigerant leakage. The situation where the detection concentration exceeds the concentration threshold due to the use of floral water or spraying alcohol disinfectant indoors is excluded, false alarms are avoided, and the problem of poor reliability of refrigerant leakage detection in the prior art of air conditioners is solved. Although the use of related technologies enhances the accuracy of refrigerant leakage detection, an early warning is only issued after the refrigerant leaks to a higher concentration. However, if a warning is issued after the refrigerant leaks to a higher concentration, intervention in the air conditioner refrigerant leak will be too late, and remedial measures cannot be taken in time, so that the cooling or heating effect of the air conditioner has been affected by insufficient refrigerant when the warning is issued, affecting the user experience.

[0040] The disclosed embodiment of the present invention discloses an air conditioner, including a communication module, a gas detection sensor and a processor. The communication module is used to send early warning information to a service center, so that the service center can dispatch orders to after-sales service to maintain the user's air conditioner according to the early warning information. The gas detection sensor is used to detect the leakage of the refrigerant and upload it to the processor for data processing. The processor is used to obtain the detection value of the gas sensor and process it, and communicate with the big data center to store the data in the big data center, or obtain data related to refrigerant leakage from the big data center for processing. The processor is also electrically connected to the above-mentioned electrical components, and is used to control the above-mentioned electrical components to perform actions.

[0041] Combination Figure 1 As shown, the embodiment of the present disclosure provides a method for controlling an air conditioner, comprising:

[0042] S01, the processor obtains the real-time value of refrigerant leakage.

[0043] S02: When the instantaneous value of refrigerant leakage is greater than a first threshold, the processor sends an early warning message to the service center.

[0044] Among them, the instantaneous value of refrigerant leakage refers to the amount of refrigerant leakage of the air conditioner within the set time. Since the instantaneous value of refrigerant leakage of the air conditioner varies under different operating parameters, using the amount of refrigerant leakage within the set time as the instantaneous value of refrigerant leakage can enhance the reliability of the data, thereby making the judgment based on the instantaneous value more accurate. The set time can be determined according to the operating parameters of the air conditioner, can be determined according to user settings, and can also be measured through experiments. The operating parameters include any one or a combination of multiple parameters of the air conditioner operation, such as the operating frequency of the compressor, the fan speed, the opening of the expansion valve, the operating frequency of the compressor and the fan speed, etc.

[0045] The warning information includes "The user's air conditioner has abnormal refrigerant leakage and needs maintenance" or "The user's air conditioner has refrigerant leakage and needs repair". The warning information can use any other words with the same meaning. After receiving the warning information, the service center sends an order to the after-sales service to maintain the user's air conditioner and eliminate the risk of leakage. After the after-sales service, the service center closes the information loop, the cumulative value of refrigerant leakage is cleared, and the statistics are restarted.

[0046] The method for controlling an air conditioner provided by the embodiment of the present disclosure is used to obtain an instantaneous value of refrigerant leakage, and when the instantaneous value of refrigerant leakage is greater than a first threshold value, an early warning message is sent to a service center. By monitoring the instantaneous leakage amount of the air conditioner's refrigerant in a relatively short period of time, the leakage rate of the air conditioner's refrigerant can be determined, thereby determining whether the current refrigerant leakage rate will affect the subsequent normal operation of the air conditioner. When the instantaneous value is greater than the first threshold value, it indicates that the refrigerant leakage is relatively fast at this time. If no remedial measures are taken, the refrigerant circulation amount of the air conditioner will soon be insufficient, thereby affecting the subsequent operation of the air conditioner. Therefore, the processor issues an early warning, thereby intervening in the leakage of the air conditioner's refrigerant in advance, so that after-sales personnel can take timely remedial measures for situations where the amount of air conditioner refrigerant may be insufficient, thereby ensuring the cooling or heating effect of the air conditioner.

[0047] Optionally, the processor determines the first threshold value according to the following method: the processor obtains an operating parameter of the air conditioner; the processor determines the first threshold value corresponding to the operating parameter of the air conditioner according to the first relationship.

[0048] The first relationship can be determined by looking up a table, by setting, or by experimental measurement. The operating parameters include any one or a combination of multiple parameters of the air conditioner operation, such as the operating frequency of the compressor, the fan speed, the opening of the expansion valve, the operating frequency of the compressor, and the fan speed.

[0049] In this way, since the refrigerant leakage conditions under different operating parameters may be different, for example, the refrigerant leakage rates under cooling operation and heating operation of the air conditioner may be different. Therefore, the processor obtains the operating parameters of the air conditioner, and determines the first threshold value corresponding to the operating parameters of the air conditioner according to the first relationship, so that the first threshold value matches the current operating parameters of the air conditioner, thereby improving the accuracy of the first threshold value.

[0050] Combination Figure 2 As shown, the embodiment of the present disclosure provides a method for controlling an air conditioner, comprising:

[0051] S01, the processor obtains the real-time value of refrigerant leakage.

[0052] S02: When the instantaneous value of refrigerant leakage is greater than a first threshold, the processor sends an early warning message to the service center.

[0053] S21, the processor clears the accumulated value of refrigerant leakage.

[0054] The cumulative value of refrigerant leakage refers to the total amount of refrigerant leakage from the initial statistical time or the last clearing time to the current time.

[0055] When the instantaneous value of refrigerant leakage is greater than the first threshold value, the processor sends an early warning message to the service center, and the service center dispatches an order to the after-sales personnel to maintain the user's air conditioner to eliminate the risk of leakage. In order to avoid continuous early warning, the cumulative value of refrigerant leakage needs to be cleared and the cumulative value of refrigerant leakage needs to be recalculated.

[0056] Combination Figure 3 As shown, the embodiment of the present disclosure provides a method for controlling an air conditioner, comprising:

[0057] S01, the processor obtains the real-time value of refrigerant leakage.

[0058] S02: When the instantaneous value of refrigerant leakage is greater than a first threshold, the processor sends an early warning message to the service center.

[0059] S31, when the instantaneous value of the refrigerant leakage is less than or equal to the first threshold, the processor counts the instantaneous value of the refrigerant leakage into the cumulative value of the refrigerant leakage.

[0060] When the instantaneous value of the refrigerant leakage is less than or equal to the first threshold value, it indicates that the refrigerant leakage rate of the air conditioner is relatively slow, and basically will not affect the refrigerant circulation of the air conditioner in a short time. However, as time accumulates, the total amount of refrigerant leakage will increase, which will still reduce the total amount of refrigerant in the air conditioner, which may affect the operation of the air conditioner. Therefore, the processor counts the instantaneous value of the refrigerant leakage into the cumulative value of the refrigerant leakage, and judges whether to intervene in the refrigerant leakage in advance from the dimension of the total amount of leakage through the cumulative value.

[0061] Combination Figure 4 As shown, the embodiment of the present disclosure provides a method for controlling an air conditioner, comprising:

[0062] S01, the processor obtains the real-time value of refrigerant leakage.

[0063] S02: When the instantaneous value of refrigerant leakage is greater than a first threshold, the processor sends an early warning message to the service center.

[0064] S41, the processor obtains the cumulative value of refrigerant leakage;

[0065] S42: When the cumulative value of refrigerant leakage is greater than a second threshold, the processor sends an early warning message to the service center.

[0066] According to the method for controlling an air conditioner provided by the embodiment of the present disclosure, when the instantaneous value of the refrigerant leakage is less than or equal to the first threshold value, it indicates that the refrigerant leakage rate of the air conditioner is relatively slow at this time, and basically will not affect the refrigerant circulation of the air conditioner in a short time. However, as time accumulates, the total amount of refrigerant leakage will increase, which will still reduce the total amount of refrigerant in the air conditioner, thereby possibly affecting the operation of the air conditioner. Therefore, not only the instantaneous value of the refrigerant leakage is used to determine whether to intervene in the refrigerant leakage, but also the cumulative value of the refrigerant leakage is used to determine whether to intervene in the refrigerant leakage. The processor obtains the cumulative value of the refrigerant leakage. When the cumulative value of the refrigerant leakage is greater than the second threshold value, it indicates that the total amount of refrigerant leakage of the air conditioner is already large, thereby affecting the total amount of refrigerant circulating in the air conditioner, and reducing the cooling or heating effect of the air conditioner, so the processor sends an early warning message to the service center. By monitoring the instantaneous value and cumulative value of the refrigerant leakage, it is determined whether to intervene in the refrigerant leakage in advance from the two dimensions of the refrigerant leakage rate and the total amount of leakage, thereby improving the accuracy of the remedial measures taken by the after-sales personnel and improving the user experience.

[0067] Optionally, the processor determines the second threshold value according to the following method: the processor obtains the total amount of refrigerant of the air conditioner; the processor determines the second threshold value corresponding to the total amount of refrigerant of the air conditioner according to the second relationship.

[0068] The second relationship may be determined by looking up a table, may be determined by setting, or may be measured by experiment.

[0069] In this way, since the measurement standards for refrigerant leakage under different total amounts of refrigerant may be different, for example, when the total amount of refrigerant is large, the same amount of refrigerant leakage will be less affected than when the total amount of refrigerant is small. Therefore, the processor obtains the total amount of refrigerant of the air conditioner, and determines the second threshold value corresponding to the total amount of refrigerant of the air conditioner according to the second relationship, so that the second threshold value matches the total amount of refrigerant of the air conditioner, thereby improving the accuracy of the second threshold value.

[0070] Optionally, when the cumulative value of the refrigerant leakage is greater than a second threshold, the method further includes: the processor clearing the cumulative value of the refrigerant leakage to zero.

[0071] In this way, when the cumulative value of refrigerant leakage is greater than the second threshold, the processor sends an early warning message to the service center, and the service center will send an order to the after-sales personnel to maintain the user's air conditioner to eliminate the risk of leakage. In order to avoid continuous early warning, the cumulative value of refrigerant leakage needs to be reset to zero and the cumulative value of refrigerant leakage needs to be recalculated.
