Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a control method for an air conditioner, an air conditioner, an electronic device, and a storage medium. Background Technology

[0002] In air conditioners with related technologies, the compressor's exhaust pipe is usually equipped with a temperature sensor, which has functions such as controlling the opening of the expansion valve, speed, and overheat protection of the exhaust temperature. When the temperature sensor wiring harness is touched, pulled, or during logistics transportation or when the outdoor unit is dropped, the temperature sensor may become loose or the temperature sensing device may fail.

[0003] Specifically, when the temperature sensor becomes detached, it cannot accurately sense the temperature, leading to a decrease in the opening of the electronic expansion valve and an increase in the exhaust temperature. This triggers the compressor's top cover thermostat, causing frequent compressor starts and stops, severely impacting the compressor's reliability. Furthermore, detached temperature sensors or malfunctioning temperature-sensing devices often go undetected. If the system experiences leaks or other severe conditions, it may be unable to implement exhaust temperature frequency limiting or shutdown protection, making the compressor prone to high-temperature demagnetization. Additionally, similar situations can occur if the compressor fails to draw or discharge air after the air conditioner starts, easily leading to misdiagnosis. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a control method for an air conditioner, which can troubleshoot air conditioner malfunctions and improve the reliability of the air conditioner.

[0005] The present invention also proposes an air conditioner that performs the above-described control method for an air conditioner.

[0006] The present invention also proposes an electronic device.

[0007] The present invention also proposes a computer-readable storage medium.

[0008] According to a first aspect of the present invention, a control method for an air conditioner includes the following steps: detecting the real-time temperature of the compressor's exhaust pipe; calculating the temperature change parameters of the exhaust pipe over a first preset time period; and determining the operating state of the air conditioner based on the temperature change parameters of the exhaust pipe.

[0009] According to the air conditioner control method of the present invention, by detecting the real-time temperature of the compressor's exhaust pipe and determining the air conditioner's operating status based on the temperature change parameters of the exhaust pipe, it is possible to quickly identify whether the air conditioner is operating normally and perform subsequent control steps based on the operating status, which is beneficial to improving the reliability of the air conditioner.

[0010] According to some embodiments of the present invention, determining the operating state of the air conditioner based on the temperature change parameter of the exhaust pipe includes: determining that the air conditioner is operating normally when the temperature change parameter of the exhaust pipe is greater than or equal to a first threshold; and determining the intake and exhaust state of the compressor when the temperature change parameter of the exhaust pipe is less than the first threshold.

[0011] In some embodiments, determining the suction and discharge state of the compressor includes: detecting the real-time temperature of the condenser coil; calculating the temperature change parameters of the condenser coil within a second preset time period; and determining the suction and discharge state of the compressor based on the temperature change parameters of the condenser coil.

[0012] In some examples, determining the compressor's intake and exhaust status based on the temperature change parameters of the condenser coil includes: determining that the compressor has no intake or exhaust when the temperature change parameters of the condenser coil are less than or equal to a second threshold; and determining that the compressor has intake and exhaust when the temperature change parameters of the condenser coil are greater than the second threshold.

[0013] In some embodiments, after determining that the compressor has no intake or exhaust, the air conditioner is controlled to issue a first alert signal.

[0014] In some embodiments, after determining that the compressor has intake and exhaust, the usage status of the first temperature sensor on the exhaust pipe is determined.

[0015] In some examples, determining the usage status of the first temperature sensor on the exhaust pipe includes: calculating the difference between the real-time temperature of the exhaust pipe and the real-time temperature of the condenser coil, and determining the usage status of the first temperature sensor based on the difference between the real-time temperature of the exhaust pipe and the real-time temperature of the condenser coil.

[0016] In some examples, determining the operating status of the first temperature sensor based on the difference between the real-time temperature of the exhaust pipe and the real-time temperature of the condenser coil includes: determining that the air conditioner is operating normally when the difference between the real-time temperature of the exhaust pipe and the real-time temperature of the condenser coil is greater than or equal to a third threshold; and determining that the operating status of the first temperature sensor is abnormal when the difference between the real-time temperature of the exhaust pipe and the real-time temperature of the condenser coil is less than the third threshold.

[0017] In some specific examples, after determining that the first temperature sensor is in an abnormal state, the method further includes: detecting the operating parameters of the first temperature sensor, and determining whether the first temperature sensor is damaged based on the operating parameters of the first temperature sensor.

[0018] Specifically, after determining that the first temperature sensor is damaged, the air conditioner is controlled to issue a second warning signal.

[0019] In some examples, determining whether the first temperature sensor is damaged based on its operating parameters includes: determining that the first temperature sensor is damaged if its operating parameters do not meet a fourth threshold; and calculating the difference between the top temperature of the compressor and the real-time temperature of the exhaust pipe if the operating parameters of the first temperature sensor meet the fourth threshold, and controlling the operating state of the air conditioner based on the difference between the top temperature of the compressor and the real-time temperature of the exhaust pipe.

[0020] In some specific examples, controlling the operating state of the air conditioner based on the difference between the top temperature of the compressor and the real-time temperature of the exhaust pipe includes: controlling the air conditioner to stop operating when the difference between the top temperature of the compressor and the real-time temperature of the exhaust pipe is greater than a fifth threshold; and controlling the air conditioner to operate normally when the difference between the top temperature of the compressor and the real-time temperature of the exhaust pipe is less than or equal to the fifth threshold.

[0021] In some specific examples, if the difference between the top temperature of the compressor and the real-time temperature of the exhaust pipe is greater than a fifth threshold, the air conditioner is also controlled to issue a third alert signal.

[0022] According to a second aspect embodiment of the present invention, the air conditioner performs the air conditioner control method as described in the above embodiments.

[0040] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0041] The following is for reference. Figures 1-9 A control method for an air conditioner according to an embodiment of the first aspect of the present invention is described.

[0042] like Figure 1 As shown, the air conditioner according to an embodiment of the present invention includes a compressor 501, an evaporator 503, a condenser 502, and an expansion valve 504. The compressor 501 is connected to the evaporator 503 and the condenser 502, and the expansion valve 504 is connected between the evaporator 503 and the condenser 502. Specifically, the suction pipe of the compressor 501 is connected to the evaporator 503, and the discharge pipe 5011 of the compressor 501 is connected to the condenser 502.

[0043] In an embodiment where the air conditioner includes an indoor unit and an outdoor unit, the compressor 501 and condenser 502 are located on the outdoor side, and the evaporator 503 and expansion valve 504 are located on the indoor side; in an embodiment where the air conditioner is a complete unit, the compressor 501, evaporator 503, condenser 502 and expansion valve 504 can all be located in the same space.

[0044] The control method for an air conditioner includes the following steps:

[0045] S1: Detect the real-time temperature of the exhaust pipe; wherein, in this embodiment, a first temperature sensor can be installed on the exhaust pipe to detect the exhaust temperature of the compressor, that is, to detect the real-time temperature of the exhaust pipe.

[0046] S2: Calculate the temperature change parameters of the exhaust pipe within the first preset time period;

[0047] Specifically, after the air conditioner has been running for a first time t1, the temperature T1 of the exhaust pipe 5011 detected by the first temperature sensor 11 on the exhaust pipe 5011 can be collected. After the air conditioner has been running for a second time t2, the temperature T2 of the exhaust pipe 5011 detected by the first temperature sensor 11 on the exhaust pipe 5011 can be collected again.

[0048] The temperature change parameter can be either the amount of temperature change or the rate of temperature change. For example, the amount of temperature change ΔT1 within a first preset time Δt1 (from the first time t1 to the second time t2) can be calculated as T2-T1, or the rate of temperature change ΔT1 / Δt1 within the first preset time can be calculated. The first time t1 can be between 1 min and 4 min.

[0049] S3: Determine the operating status of the air conditioner based on the temperature change parameters of the exhaust pipe.

[0050] According to the air conditioner control method of the present invention, by detecting the real-time temperature of the compressor's exhaust pipe and determining the air conditioner's operating status based on the temperature change parameters of the exhaust pipe, it is possible to quickly identify whether the air conditioner is operating normally and perform subsequent control steps based on the operating status, which is beneficial to improving the reliability of the air conditioner.

[0051] Specifically, such as Figure 1 and Figure 2 As shown, when the temperature change parameter is greater than or equal to the first threshold, the air conditioner is determined to be operating normally; when the temperature change parameter is less than the first threshold, the compressor's intake and exhaust status is determined.

[0052] In other words, after the air conditioner is turned on, if the temperature rise of the exhaust pipe 5011 reaches a certain value, it can be determined that the air conditioner is in normal operation. If the temperature rise of the exhaust pipe 5011 does not reach a certain value, the air conditioner may be in normal operation, or the compressor 501 may be malfunctioning or abnormal. Therefore, subsequent steps are required to further determine the intake and exhaust status of the compressor 501, that is, to determine whether the compressor 501 is working normally, so as to ensure the reliability of the compressor 501.

[0053] For ease of understanding, the temperature change parameter can be described as the amount of temperature change. Correspondingly, the first threshold can be 0℃-2℃, for example, the first threshold can be 1℃, 1.5℃, 2℃, etc. Taking a first threshold of 1℃ as an example, if the calculated temperature change of the exhaust pipe 5011 is greater than or equal to 1℃, then the air conditioner is determined to be operating normally. If the calculated temperature change of the exhaust pipe 5011 is less than 1℃, then subsequent steps are required to determine the intake and exhaust status of the compressor 501.

[0054] Among them, such as Figure 3 As shown, step S3 includes:

[0055] S31: Detect the real-time temperature of the condenser coil; wherein, a second temperature sensor can be installed on the condenser coil to detect the real-time temperature of the condenser coil.

[0056] S32: Calculate the temperature change parameters of the condenser coil within the second preset time period;

[0057] S33: Determine the compressor's suction and discharge status based on the temperature change parameters of the condenser coil.

[0058] By determining the operating status of compressor 501 based on the temperature change parameters of condenser 502 coil within a second preset time, it is possible to quickly identify whether compressor 501 is operating normally and to perform subsequent control steps based on the operating status of compressor 501. If compressor 501 does not perform suction and discharge, it proves that compressor 501 is working normally, and it is necessary to stop the compressor 501 and perform maintenance. If compressor 501 can perform suction and discharge normally, it is necessary to further check whether other components are faulty. This can avoid frequent start and stop of compressor 501 and improve the reliability of compressor 501.

[0059] Specifically, step S22 includes: determining that the compressor has no suction or discharge when the temperature change parameter is less than or equal to the second threshold; and determining that the compressor has suction or discharge when the temperature change parameter is greater than the second threshold.

[0060] In other words, after starting the air conditioner, if the temperature rise of the condenser coil 502 reaches a certain value, it can be determined that the compressor 501 can normally draw in and discharge gas. At this time, the compressor 501 is in normal operation. Further investigation is needed to check whether other components have malfunctioned. This can avoid frequent start-stop of the compressor 501 and help improve the reliability of the compressor 501. If the temperature rise of the condenser coil 502 does not reach a certain value, that is, the temperature of the condenser coil 502 does not rise significantly, it proves that the compressor 501 has not compressed the refrigerant into a high-temperature and high-pressure gas. At this time, the compressor 501 may be abnormal or malfunctioning, and it is necessary to stop the machine and repair the compressor 501.

[0061] Specifically, after the air conditioner has been running for a third time t3, the temperature T3 detected by the second temperature sensor on the condenser coil can be collected. After the air conditioner has been running for a fourth time t4, the temperature T4 detected by the second temperature sensor on the condenser coil can be collected again.

[0062] The temperature change parameter can be either the amount of temperature change or the rate of temperature change. For example, the amount of temperature change ΔT3 within the second preset time Δt2 (from the third time t3 to the fourth time t4) can be calculated as T4-T3, or the rate of temperature change ΔT3 / Δt2 within the second preset time can be calculated.

[0063] For ease of understanding, the temperature change parameter can be described as a temperature change amount. Correspondingly, the second threshold can be 5℃-10℃. Specifically, the second threshold can be 6℃, 8℃, 10℃, etc. Taking a second threshold of 6℃ as an example, if the calculated temperature change parameter of the condenser 502 coil within the second preset time is less than or equal to 6℃, it is determined that the compressor 501 is not normally drawing or discharging gas, that is, the compressor 501 has an abnormality or malfunction. If the calculated temperature change parameter of the condenser 502 coil within the second preset time is greater than 6℃, it is determined that the compressor 501 is normally drawing and discharging gas, and the compressor 501 has no abnormality or malfunction.

[0064] In some embodiments, if the compressor has no intake or exhaust, the air conditioner can then be controlled to issue a first warning signal, for example, to remind the user that the machine needs to be stopped and the compressor needs to be repaired. The user can obtain the fault type through the air conditioner's warning, which facilitates after-sales service and troubleshooting.

[0065] like Figure 4As shown, in some embodiments, in step S3: if it is determined that the compressor has suction and exhaust, the control method of the air conditioner further includes step S4: determining the usage status of the first temperature sensor on the exhaust pipe.

[0066] In other words, after the system finds that the compressor 501 has no abnormalities or faults, it needs to determine the usage status of the first temperature sensor 11 on the exhaust pipe 5011 in order to check whether the first temperature sensor 11 on the exhaust pipe 5011 is damaged or loose.

[0067] In checking the usage status of the first temperature sensor 11 on the exhaust pipe 5011, the usage status of the first temperature sensor 11 can be determined by calculating the difference between the real-time temperature of the exhaust pipe 5011 and the real-time temperature of the condenser coil 502. The usage status of the first temperature sensor 11 can be determined based on the difference between the real-time temperature of the exhaust pipe 5011 detected by the first temperature sensor 11 and the real-time temperature of the condenser coil 502 detected by the second temperature sensor 12.

[0068] like Figure 4 and Figure 5 As shown, in some specific examples, step S4 includes:

[0069] If the difference is greater than or equal to a third threshold, the air conditioner is controlled to operate normally, wherein the third threshold can be 2℃-6℃; if the difference is less than the third threshold, the first temperature sensor is determined to be in an abnormal state.

[0070] Specifically, after the air conditioner is turned on, if the difference between the real-time temperature of the exhaust pipe 5011 detected by the first temperature sensor 11 and the real-time temperature of the condenser coil 502 detected by the second temperature sensor 12 reaches a certain value, it can be determined that the air conditioner is in normal operation. If the difference between the real-time temperature of the exhaust pipe 5011 detected by the first temperature sensor 11 and the real-time temperature of the condenser coil 502 detected by the second temperature sensor 12 does not reach a certain value, it is determined that the first temperature sensor 11 on the exhaust pipe 5011 is abnormal. For example, the electrical components of the first temperature sensor 11 may be damaged, or the first temperature sensor 11 may be loose, causing the first temperature sensor 11 to be unable to accurately detect the real-time temperature of the exhaust pipe 5011.

[0071] In other words, if the temperature of the exhaust pipe 5011 detected by the first temperature sensor 11 is lower than the temperature of the coil of the condenser 502 when the temperature of the condenser 502 is normal, it indicates that there is an abnormality in the first temperature sensor 11 on the exhaust pipe 5011. It may be that it is loose and cannot accurately sense the temperature, or it may be that the temperature sensing element of the first temperature sensor 11 has failed. Further troubleshooting is required.

[0072] Specifically, the third threshold can be 3℃, 4℃, 6℃, etc. Taking a third threshold of 4℃ as an example, if the difference between the real-time temperature of the exhaust pipe 5011 and the real-time temperature of the condenser coil 502 is greater than or equal to 4℃, the air conditioner is determined to be in normal operation. If the difference between the real-time temperature of the exhaust pipe 5011 and the real-time temperature of the condenser coil 502 is less than 4℃, the first temperature sensor 11 is determined to be abnormal.

[0073] In step S4, if the first temperature sensor 11 is damaged, the air conditioner will be controlled to issue a second prompt signal. For example, the user can be reminded to stop the machine and replace or repair the first temperature sensor 11. The user can get the fault type through the prompt of the air conditioner, which is convenient for after-sales service and fault diagnosis.

[0074] like Figure 6 As shown, in some embodiments, if the first temperature sensor is in an abnormal state in step S4, step S5 is further included: detecting the operating parameters of the first temperature sensor and determining whether the first temperature sensor is damaged based on the operating parameters of the first temperature sensor.

[0075] The operating parameters can be either the voltage or resistance value of the first temperature sensor 11. By detecting the operating parameters of the first temperature sensor 11, the operating status of the first temperature sensor 11 can be further determined, thereby enabling fault diagnosis and improving the reliability of the air conditioner.

[0076] like Figure 6 and Figure 7 As shown, in some examples, step S5 includes:

[0077] If the operating parameters do not meet the fourth threshold, it is determined that the first temperature sensor 11 is damaged. The operating parameters can be the voltage of the first temperature sensor 11 or the resistance of the first temperature sensor 11. When the operating parameters are resistance, the fourth threshold can be 1.5V-2.5V.

[0078] If the operating parameters meet the fourth threshold, calculate the difference between the top temperature of the compressor and the real-time temperature of the exhaust pipe, and determine the operating status of the air conditioner based on the difference between the top temperature of the compressor and the real-time temperature of the exhaust pipe.

[0079] It should be noted that if the first temperature sensor 11 on the exhaust pipe 5011 is damaged, its resistance value will be 0 or infinite, and the voltage value of the first temperature sensor 11 will inevitably exceed the normal range.

[0080] Taking the voltage value of the first temperature sensor 11 as an example, the fourth threshold can be 1.5V-2.5V, or it can be 2V or 2.5V. With the fourth threshold of 2V, if the detected voltage value of the first temperature sensor 11 exceeds 2V, it is determined that the first temperature sensor 11 on the exhaust pipe 5011 is faulty. If the detected voltage value of the first temperature sensor 11 is less than 2V, the first temperature sensor 11 may be loose or detached.

[0081] When the first temperature sensor 11 becomes loose, it cannot accurately sense the temperature, which will cause the opening of the air conditioner's expansion valve 504 to decrease and the exhaust temperature to rise. This will trigger the operation of the thermostat on the compressor 501, causing the compressor 501 to start and stop frequently. This application detects that the first temperature sensor 11 may become loose or fall off through the above method. The subsequent steps further determine the operating status of the air conditioner, avoiding frequent starts of the compressor 501 and helping to ensure the reliability of the compressor 501.

[0082] Specifically, if the difference is greater than a fifth threshold (which can be between 15℃ and 70℃), the air conditioner will stop operating; if the difference is less than or equal to the fifth threshold, the air conditioner will operate normally.

[0083] Specifically, the fifth threshold can be 20℃, 30℃, 60℃, 70℃, etc. Taking a fifth threshold of 30℃ as an example, if the difference between the top temperature of the compressor 501 and the real-time temperature of the exhaust pipe 5011 is less than or equal to 30℃, the air conditioner can operate normally. If the difference between the top temperature of the compressor 501 and the real-time temperature of the exhaust pipe 5011 is greater than 30℃, the unit must be shut down immediately.

[0084] It should be noted that when the system experiences extreme conditions such as leakage, ice blockage, or valve failure, the motor of compressor 501 will continue to heat up. Due to the lack of refrigerant heat transfer, the temperature difference between the exhaust pipe 5011 and the casing of compressor 501 will increase. If the first temperature sensor 11 on the exhaust pipe 5011 fails, the first temperature sensor 11 cannot accurately control the opening of the expansion valve 504 or perform high-temperature frequency limiting of the exhaust. Therefore, the system must be shut down immediately for protection.

[0085] If the difference is greater than the fifth threshold, the air conditioner is also controlled to issue a third prompt signal, which allows the user to obtain the fault type through the air conditioner's prompt, facilitating after-sales service.

[0086] The following is combined Figures 1-9 An air conditioner according to an embodiment of the second aspect of the present invention is described.

[0087] According to an embodiment of the present invention, the air conditioner performs the control method of the air conditioner as described in the above embodiment.

[0088] Since the control method of the air conditioner according to the embodiment of the present invention has the above-mentioned beneficial technical effects, the air conditioner according to the embodiment of the present invention also has the above-mentioned technical effects. By detecting the real-time temperature of the exhaust pipe 5011 of the compressor 501, the operating status of the air conditioner is determined according to the temperature change parameter of the exhaust pipe 5011. That is, it is possible to quickly identify whether the air conditioner is operating normally, and to perform subsequent control steps according to the operating status, which is beneficial to improving the reliability of the air conditioner.

[0089] like Figure 8 As shown, in some embodiments, the air conditioner includes a compressor 501, an evaporator 503, a condenser 502, and an expansion valve 504. The compressor 501 is connected to the evaporator 503 and the condenser 502, the expansion valve 504 is connected between the evaporator 503 and the condenser 502, the suction pipe of the compressor 501 is connected to the evaporator 503, and the discharge pipe 5011 of the compressor 501 is connected to the condenser 502.

[0090] In this embodiment, a first temperature sensor 11 is provided on the exhaust pipe 5011 to detect the exhaust temperature of the compressor 501, that is, to detect the real-time temperature of the exhaust pipe 5011.

[0091] like Figure 9 As shown, according to some embodiments of the present invention, the air conditioner includes a detection module 10, a calculation module 20, and a control module 30. The detection module 10 includes a first temperature sensor 11, which is disposed on the exhaust pipe 5011 of the compressor 501 and is used to detect the real-time temperature of the exhaust pipe 5011. The calculation module 20 communicates with the first temperature sensor 11 on the exhaust pipe 5011 and the control module 30. The calculation module 20 is used to calculate the temperature change parameters of the exhaust pipe 5011 within a first preset time. The control module 30 can determine the operating status of the air conditioner based on the temperature change parameters of the exhaust pipe 5011 within the first preset time calculated by the calculation module 20.

[0092] According to the embodiment of the present invention, the air conditioner uses a first temperature sensor 11 to detect the real-time temperature of the exhaust pipe 5011 of the compressor 501, and a calculation module 20 to calculate the temperature change parameters of the exhaust pipe 5011 within a first preset time. The control module 30 can determine the operating status of the air conditioner based on the calculation results of the calculation module 20. That is, it can quickly identify whether the air conditioner is operating normally and perform subsequent control steps based on the operating status, which is beneficial to improving the reliability of the air conditioner.

[0093] In some embodiments, when the temperature change parameter of the exhaust pipe 5011 calculated by the calculation module 20 is greater than or equal to the first threshold, the control module 30 determines that the air conditioner is operating normally, thereby controlling the air conditioner to continue operating; when the temperature change parameter of the exhaust pipe 5011 calculated by the calculation module 20 is less than the first threshold, the control module 30 determines the intake and exhaust state of the compressor 501.

[0094] In other words, after the air conditioner is started, if the temperature rise of the exhaust pipe 5011 calculated by the calculation module 20 reaches a certain value, the control module 30 can determine that the air conditioner is in normal operation. Therefore, the air conditioner does not need to be stopped. If the temperature rise of the exhaust pipe 5011 calculated by the calculation module 20 does not reach a certain value, the air conditioner may be in normal operation, or the compressor 501 may be malfunctioning or abnormal. Therefore, subsequent steps are required to further determine the intake and exhaust status of the compressor 501, that is, to determine whether the compressor 501 is working normally, so as to ensure the reliability of the compressor 501.

[0095] In some embodiments, the detection module 10 further includes a second temperature sensor 12, which communicates with the calculation module 20 and the control module 30. The calculation module 20 is also used to calculate the temperature change parameters of the condenser 502 coil within a second preset time. The control module 30 determines the suction and discharge state of the compressor 501 based on the calculation results of the calculation module 20.

[0096] The control module 30 determines the operating status of the compressor 501 based on the temperature change parameters of the condenser 502 coil within a second preset time. This allows for quick identification of whether the compressor 501 is operating normally. Based on the operating status of the compressor 501, subsequent control steps are performed. If the compressor 501 is not drawing or discharging, it indicates that the compressor 501 is operating normally, and it needs to be stopped and repaired. If the compressor 501 can draw and discharge normally, further investigation is needed to check whether other components are malfunctioning. This avoids frequent start-stop of the compressor 501 and improves the reliability of the compressor 501.

[0097] Specifically, if the temperature rise of the condenser 502 coil reaches a certain value, the control module 30 can determine that the compressor 501 can normally draw and discharge gas. At this time, the compressor 501 is in normal operation. Further investigation is needed to check whether other components have malfunctioned. This can avoid frequent start-stop of the compressor 501 and improve the reliability of the compressor 501. If the temperature rise of the condenser 502 coil does not reach a certain value, that is, the temperature of the condenser 502 coil does not rise significantly, it proves that the compressor 501 has not compressed the refrigerant into a high-temperature and high-pressure gas. At this time, the compressor 501 may be abnormal or malfunctioning. It is necessary to stop the compressor 501 and repair it.

[0098] In some embodiments, the air conditioner further includes a first prompt module 41, which communicates with the control module 30. After determining that the compressor 501 has no exhaust, the control module 30 controls the first prompt module 41 to issue a first prompt signal, which can remind the user to stop the machine and repair the compressor 501. The user can obtain the fault type through the prompt of the air conditioner, which is convenient for after-sales service and fault diagnosis.

[0099] According to some embodiments of the present invention, after the control module 30 determines that the compressor 501 has suction and discharge, the calculation module 20 calculates the difference between the real-time temperature of the exhaust pipe 5011 and the real-time temperature of the condenser coil 502. If the difference between the two is greater than or equal to a third threshold, the control module 30 determines that the air conditioner is operating normally. If the difference between the two is less than the third threshold, the control module 30 determines that the first temperature sensor 11 is in an abnormal state.

[0100] In other words, if the temperature of the exhaust pipe 5011 detected by the first temperature sensor 11 is lower than the temperature of the coil of the condenser 502 when the temperature of the condenser 502 is normal, it indicates that there is an abnormality in the first temperature sensor 11 on the exhaust pipe 5011. It may be that it is loose and cannot accurately sense the temperature, or it may be that the temperature sensing element of the first temperature sensor 11 has failed. Further troubleshooting is required.

[0101] In some embodiments, the air conditioner further includes a second prompt module 42, which communicates with the control module 30. After determining that the first temperature sensor 11 is damaged, the control module 30 controls the second prompt module 42 to issue a second prompt signal. The user can be reminded to stop the air conditioner and replace or repair the first temperature sensor 11. The user can obtain the fault type through the prompt of the air conditioner, which is convenient for after-sales service and fault diagnosis.

[0102] According to some embodiments of the present invention, after the control module 30 determines that the first temperature sensor 11 is in an abnormal state, the detection module 10 detects the operating parameters of the first temperature sensor 11. If the operating parameters do not meet the fourth threshold, the control module 30 determines that the first temperature sensor 11 is damaged. If the operating parameters meet the fourth threshold, the control module 30 determines that the first temperature sensor 11 is abnormal.

[0103] It should be noted that if the first temperature sensor 11 on the exhaust pipe 5011 is damaged, its resistance will be 0 or infinite, and the voltage value of the first temperature sensor 11 will inevitably exceed the normal range. Therefore, the operating parameter can be either the voltage value or the resistance value of the first temperature sensor 11.

[0104] After the first temperature sensor 11 malfunctions, the calculation module 20 also calculates the difference between the top temperature of the compressor 501 and the real-time temperature of the exhaust pipe 5011. If the difference is greater than the fifth threshold, the control module 30 controls the air conditioner to stop running. If the difference is less than or equal to the fifth threshold, the control module 30 controls the air conditioner to run normally.

[0105] In some embodiments, the air conditioner further includes a third prompt module 43, which communicates with the control module 30. When the difference between the top temperature of the compressor 501 and the real-time temperature of the exhaust pipe 5011 is greater than a fifth threshold, the control module 30 controls the third prompt module 43 to issue a third prompt signal. The user can obtain the fault type through the prompt of the air conditioner, which is convenient for after-sales service.
