[0001] The present application relates to the technical field of air conditioning control, and in particular to an air conditioning control method, device, air conditioner and computer-readable storage medium. Background Art

[0002] During the operation of the air conditioner, due to the differences in the external environment and components, as well as long-term operation, the two devices become dirty and blocked, which can easily cause the heat exchange between the two devices to decay and the air conditioner's operating status to exceed its reliability requirements. As time accumulates, it will cause the air conditioner to malfunction or be damaged, thereby affecting the normal use of the air conditioner.

[0003] At present, the status of air conditioners is often judged by parameters such as exhaust or external disk temperature. However, due to the single detection method, there are problems such as inaccurate detection results and poor reliability. Summary of the Invention

[0036] The air conditioning control method provided in the embodiment of the present application can determine that the outer disk is too high if the difference between the outer disk temperature and the outdoor ambient temperature is greater than or equal to a preset first cooling threshold value. Therefore, it can be further determined based on the first cooling high temperature difference current and the second cooling high temperature difference current whether the air conditioner is in a normal state, an abnormal compressor state, a dirty and blocked condenser state, or a liquid-deficient state, thereby accurately judging the air conditioner state when the outer disk temperature is high.

[0057] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0058] Figure 1 For a block diagram of the air conditioner 10 provided in the embodiment of the present application, see Figure 1 , the air conditioner includes an outdoor unit 100 and an indoor unit 110 .

[0059] Optionally, the outdoor unit 100 is provided with a controller, which is used to execute a computer program to implement the air conditioning control method provided in the embodiment of the present application.

[0060] Optionally, the air conditioner 10 may be provided with a temperature acquisition device, such as a temperature sensor, for acquiring outdoor ambient temperature, inner disk temperature, outer disk temperature, etc., and sending the acquired temperatures to the controller.

[0061] Next, the above Figure 1 The air conditioner 10 in the embodiment is the execution subject, and the air conditioning control method provided by the embodiment of the present application is exemplarily introduced in combination with the flow chart. Specifically, Figure 2 A flow chart of the air conditioning control method provided in the embodiment of the present application is shown in FIG. Figure 2 , the method comprising:

[0062] Step S20, when the air conditioner is running, obtaining the outdoor ambient temperature, the compressor current, and the coil temperature corresponding to the current operating mode;

[0063] Optionally, the air conditioner can obtain the outdoor ambient temperature, compressor current and coil temperature corresponding to the current operating mode in real time during operation, or it can obtain the outdoor ambient temperature, compressor current and coil temperature corresponding to the current operating mode once every preset time period.

[0064] It can be understood that in this embodiment, the coil temperatures that need to be obtained are different when the air conditioner is in different operating modes.

[0065] Step S21 , determining the current operating state of the air conditioner according to the current operating mode, coil temperature, outdoor ambient temperature, and compressor current.

[0066] Optionally, the air conditioner may comprehensively determine the current operating state of the air conditioner according to the current operating mode, coil temperature, outdoor ambient temperature, and compressor current.

[0067] Optionally, the current operating state may include a normal operating state or an abnormal operating state.

[0068] Optionally, in order to ensure that the user can be informed and dealt with in a timely manner when the current operating status of the air conditioner is abnormal, the air conditioner can notify the user when it is determined that the current operating status of the air conditioner is abnormal, such as prompting the user through an abnormal warning light, or prompting the user on the terminal device through the air conditioner control software. This application does not impose too many restrictions on the prompt method.

[0069] The air conditioning control method provided in the embodiment of the present application is that after obtaining the outdoor ambient temperature, the compressor current and the coil temperature corresponding to the current operating mode, the air conditioner can determine the current operating status of the air conditioner based on the current operating mode, the corresponding coil temperature, the outdoor ambient temperature and the compressor current, and a combination of multiple reference factors. Therefore, the detection results can be guaranteed to be more accurate and the reliability of the detection can be improved.

[0070] Optionally, for the air conditioner, its operating mode includes a cooling mode and a heating mode. In one possible implementation, the corresponding coil temperature in the heating mode may be the inner coil temperature, and the corresponding coil temperature in the cooling mode may be the outer coil temperature.

[0071] Next, we will introduce the heating mode with the help of the flow chart. Figure 2 On the basis of Figure 3 For another flow chart of the air conditioning control method provided in the embodiment of the present application, please refer to Figure 3 , the above step S21 can also be implemented by the following steps:

[0072] Step S21-1: In heating mode, if the difference between the internal disk temperature and the outdoor ambient temperature is greater than or equal to a preset first heating threshold, the current operating state of the air conditioner is determined based on the compressor current and the heating high temperature difference current.

[0073] Optionally, if the difference between the inner disk temperature and the outdoor ambient temperature is greater than or equal to the preset first heating threshold, it can be determined that the inner disk temperature is too high at this time, and the air conditioner may be in an abnormal operating state. Therefore, the compressor current and the preset heating high temperature difference current can be combined to further determine the current operating state of the air conditioner.

[0074] Step S21-2: If the difference between the internal disk temperature and the outdoor ambient temperature is less than or equal to the preset second heating threshold, the current operating state of the air conditioner is determined according to the compressor current and the heating low temperature difference current.

[0075] Optionally, if the difference between the inner disk temperature and the outdoor ambient temperature is less than or equal to the preset second heating threshold, it can be determined that the inner disk temperature is low at this time, and the air conditioner may also be in an abnormal operating state. Therefore, the compressor current and the preset heating low temperature difference current can be combined to further determine the current operating state of the air conditioner.

[0076] In step S21 - 3 , if the difference between the internal disk temperature and the outdoor ambient temperature is greater than the preset second heating threshold and less than the preset first heating threshold, it is determined that the current operating state of the air conditioner is normal.

[0077] Optionally, if the difference between the internal disk temperature and the outdoor ambient temperature is greater than the preset second heating threshold and less than the preset first heating threshold, it can be determined that the internal disk temperature is in a relatively suitable temperature range, and therefore the current operating state of the air conditioner can be determined to be normal.

[0078] Optionally, considering that there is a certain linear relationship between the inner disk temperature and the outdoor ambient temperature, that is, the higher the outdoor ambient temperature, the higher the inner disk temperature, the first heating threshold and the second heating threshold can be determined according to the outdoor ambient temperature.

[0079] In a possible implementation, a heating outdoor environment temperature threshold may be set to determine the first heating threshold and the second heating threshold.

[0080] Optionally, the heating outdoor environment temperature threshold may be determined according to actual application conditions. For example, the heating outdoor environment temperature threshold may be set to 15°C.

[0081] Optionally, if the outdoor ambient temperature is less than the heating ambient temperature threshold, it can be determined that the outdoor ambient temperature is low, and therefore the first heating threshold and the second heating threshold can be set relatively low. For example, when the outdoor ambient temperature is less than the heating ambient temperature threshold, the first heating threshold has a value range of 35°C to 50°C, and the second heating threshold has a value range of 20°C to 45°C. Then, the corresponding first heating threshold and second heating threshold can be determined in advance within the corresponding value range based on actual conditions, for example, the first heating threshold is set to 35°C and the second heating threshold is set to 25°C.

[0082] Optionally, if the outdoor ambient temperature is greater than or equal to the heating ambient temperature threshold, it can be determined that the outdoor ambient temperature is high, and therefore the first heating threshold and the second heating threshold can be set relatively high. For example, when the outdoor ambient temperature is greater than or equal to the heating ambient temperature threshold, the first heating threshold has a value range of 35°C to 55°C, and the second heating threshold has a value range of 20°C to 45°C. The corresponding first heating threshold and second heating threshold can be determined in advance within the corresponding value range based on actual conditions, for example, the first heating threshold is set to 40°C and the second heating threshold is set to 30°C.

[0083] It can be understood that the first heating threshold when the outdoor ambient temperature is high should be greater than the first heating threshold when the outdoor ambient temperature is low; the second heating threshold when the outdoor ambient temperature is high should be greater than the second heating threshold when the outdoor ambient temperature is low.

[0084] In addition, considering that there is a certain linear relationship between the compressor current and the outdoor ambient temperature, that is, the higher the outdoor ambient temperature, the higher the compressor current, the corresponding heating high temperature difference current and heating low temperature difference current can also be determined according to the outdoor ambient temperature.

[0085] Similarly, if the outdoor ambient temperature is lower than the heating ambient temperature threshold, it can be determined that the outdoor ambient temperature is relatively low, so the heating high temperature difference current and the heating low temperature difference current can be set relatively low; if the outdoor ambient temperature is greater than or equal to the heating ambient temperature threshold, it can be determined that the outdoor ambient temperature is relatively high, so the heating high temperature difference current and the heating low temperature difference current can be set relatively high.

[0086] In one possible implementation, after obtaining the outdoor ambient temperature, the air conditioner can first determine whether the outdoor ambient temperature is lower than the preset heating outdoor ambient temperature threshold. If it is lower than the heating outdoor ambient temperature threshold, it is determined that the outdoor ambient temperature is low at this time. Therefore, the first heating threshold and the second heating threshold that should be used as the basis for judgment can be determined to be the thresholds set for the case where the outdoor ambient temperature is low, and the heating high temperature difference current and the heating low temperature difference current are determined to be the current values ​​set for the case where the outdoor ambient temperature is low; if it is greater than or equal to the heating outdoor ambient temperature threshold, it is determined that the outdoor ambient temperature is high at this time. Therefore, the first heating threshold and the second heating threshold that should be used as the basis for judgment can be determined to be the thresholds set for the case where the outdoor ambient temperature is high, and the heating high temperature difference current and the heating low temperature difference current are determined to be the current values ​​set for the case where the outdoor ambient temperature is high.

[0087] Optionally, the heating high temperature difference current may include a first heating high temperature difference current and a second heating high temperature difference current. It can be understood that the first heating high temperature difference current when the outdoor ambient temperature is relatively high should be greater than the first heating high temperature difference current when the outdoor ambient temperature is relatively low; the second heating high temperature difference current when the outdoor ambient temperature is relatively high should be greater than the second heating high temperature difference current when the outdoor ambient temperature is relatively low.

[0088] Optionally, if the outdoor ambient temperature is low, the value range of the first heating high temperature difference current can be 1°C to 1.2°C, and the value range of the second heating high temperature difference current can be 0.7°C to 1.1°C. The corresponding first heating high temperature difference current and second heating high temperature difference current can be determined in advance within the corresponding value range according to actual conditions, for example, the first heating high temperature difference current is set to 1.15°C and the second heating high temperature difference current is set to 0.88°C.

[0089] Optionally, if the outdoor ambient temperature is high, the value range of the first heating high temperature differential current can be 1.1°C to 1.3°C, and the value range of the second heating high temperature differential current can be 0.8°C to 1.2°C. The corresponding first heating high temperature differential current and second heating high temperature differential current can be determined in advance within the corresponding value range according to actual conditions. For example, the first heating high temperature differential current is set to 1.2°C and the second heating high temperature differential current is set to 0.91°C.

[0090] In this embodiment, the air conditioner can determine the current operating state of the air conditioner specifically according to the compressor current, the first heating high temperature difference current, and the second heating high temperature difference current.

[0091] Specifically, determining the current operating state of the air conditioner according to the compressor current and the heating high temperature difference current in step S21-1 can be achieved by the following steps:

[0092] If the compressor current is greater than or equal to the first heating high temperature difference current, it is determined that the air conditioner is in an abnormal compressor state or the evaporator is dirty and blocked; if the compressor current is less than or equal to the second heating high temperature difference current, it is determined that the air conditioner is in a liquid shortage state; if the compressor current is greater than the second heating high temperature difference current and less than the first heating high temperature difference current, it is determined that the air conditioner is in a normal state.

[0093] Optionally, if the compressor current is greater than or equal to the first heating high temperature difference current, it can be determined that the air conditioner has abnormal heat dissipation, and the quality and flow of the refrigerant liquid are relatively large, so there may be an abnormal compressor condition or the evaporator is dirty and blocked.

[0094] Optionally, the air conditioner may notify the user that the air conditioner may be in an abnormal compressor state or a dirty evaporator blockage state when the compressor current is greater than or equal to the first heating high temperature difference current.

[0095] Optionally, if the compressor current is less than or equal to the second heating high temperature difference current, it can be determined that the refrigerant liquid flow in the air conditioner is small at this time, and therefore there may be a liquid shortage condition.

[0096] Optionally, the air conditioner may notify the user that the air conditioner may be in a liquid shortage state when the compressor current is less than or equal to the second heating high temperature difference current.

[0097] Optionally, if the compressor current is greater than the second heating high temperature difference current and less than the first heating high temperature difference current, it can be determined that the air conditioner is operating normally at this time.

[0098] Optionally, the heating low-temperature difference current may include a first heating low-temperature difference current and a second heating low-temperature difference current. It can be understood that the first heating low-temperature difference current when the outdoor ambient temperature is relatively high should be greater than the first heating low-temperature difference current when the outdoor ambient temperature is relatively low; the second heating low-temperature difference current when the outdoor ambient temperature is relatively high should be greater than the second heating low-temperature difference current when the outdoor ambient temperature is relatively low.

[0099] Optionally, if the outdoor ambient temperature is low, the value range of the first heating low temperature difference current can be 1.1℃~1.3℃, and the value range of the second heating low temperature difference current can be 0.8℃~1.1℃. The corresponding first heating low temperature difference current and second heating low temperature difference current can be determined in advance within the corresponding value range according to actual conditions, for example, the first heating low temperature difference current is set to 1.15℃ and the second heating low temperature difference current is set to 0.9℃.

[0100] Optionally, if the outdoor ambient temperature is high, the value range of the first heating low temperature difference current can be 1.2°C to 1.4°C, and the value range of the second heating low temperature difference current can be 0.9°C to 1.3°C. The corresponding first heating low temperature difference current and second heating low temperature difference current can be determined in advance within the corresponding value range according to actual conditions, for example, the first heating low temperature difference current is set to 1.2°C and the second heating low temperature difference current is set to 1°C.

[0101] In this embodiment, the air conditioner can determine the current operating state of the air conditioner specifically according to the compressor current, the first heating low temperature difference current, and the second heating low temperature difference current.

[0102] Specifically, determining the current operating state of the air conditioner according to the compressor current and the heating high temperature difference current in step S21-1 can be achieved by the following steps:

[0103] If the compressor current is greater than or equal to the first heating low-temperature difference current, it is determined that the air conditioner is in an abnormal compressor state; if the compressor current is less than or equal to the second heating low-temperature difference current, it is determined that the air conditioner is in a condenser dirty and blocked state or a liquid-deficient state; if the compressor current is greater than the second heating low-temperature difference current and less than or equal to the first heating low-temperature difference current, it is determined that the air conditioner is in a normal state.

[0104] Optionally, if the compressor current is greater than or equal to the first heating low temperature difference current, it can be determined that the air conditioner has abnormal heat dissipation, and the quality and flow of the refrigerant liquid are relatively large. However, since the inner disk temperature is relatively low at this time, the air conditioner may have an abnormal compressor.

[0105] Optionally, the air conditioner may notify the user that the air conditioner may be in an abnormal compressor state when the compressor current is greater than or equal to the first heating low temperature difference current.

[0106] Optionally, if the compressor current is less than or equal to the second heating low temperature difference current, it can be determined that the refrigerant liquid flow in the air conditioner is small, or the heat exchange of the outdoor unit is poor, so there may be a lack of liquid or the condenser is dirty and blocked.

[0107] Optionally, when the compressor current is less than or equal to the second heating low temperature difference current, the air conditioner may notify the user that the air conditioner may be in a liquid shortage state or the condenser may be dirty and blocked.

[0108] Optionally, if the compressor current is greater than the second heating low temperature difference current and less than the first heating low temperature difference current, it can be determined that the air conditioner is operating normally at this time.

[0109] Next, we will introduce the cooling mode with the help of the flow chart. Figure 2 On the basis of Figure 4 For another flow chart of the air conditioning control method provided in the embodiment of the present application, please refer to Figure 4 , the above step S21 can also be implemented by the following steps:

[0110] Step S21-4, in cooling mode, if the difference between the external disk temperature and the outdoor ambient temperature is greater than or equal to a preset first cooling threshold, determining the current operating state of the air conditioner based on the compressor current and the cooling high temperature difference current;

[0111] Optionally, if the difference between the external disk temperature and the outdoor ambient temperature is greater than or equal to a preset first cooling threshold, it can be determined that the external disk temperature is too high at this time, and the air conditioner may be in an abnormal operating state. Therefore, the compressor current and the preset cooling high temperature difference current can be combined to further determine the current operating state of the air conditioner.

[0112] Step S21-5: If the difference between the external disk temperature and the outdoor ambient temperature is less than or equal to a preset second cooling threshold, the current operating state of the air conditioner is determined based on the compressor current and the cooling low temperature difference current;

[0113] Optionally, if the difference between the external disk temperature and the outdoor ambient temperature is less than or equal to a preset second cooling threshold, it can be determined that the external disk temperature is low at this time, and the air conditioner may be in an abnormal operating state. Therefore, the compressor current and the preset cooling low temperature difference current can be combined to further determine the current operating state of the air conditioner.

[0114] Step S21-6: If the difference between the external disk temperature and the outdoor ambient temperature is greater than the preset second cooling threshold and less than the preset first cooling threshold, it is determined that the current operating state of the air conditioner is normal.

[0115] Optionally, if the difference between the external disk temperature and the outdoor ambient temperature is greater than the preset second cooling threshold and less than the preset first cooling threshold, it can be determined that the external disk temperature is in a relatively suitable temperature range at this time, and therefore it can be determined that the current operating state of the air conditioner is normal.

[0116] Optionally, considering that there is a certain linear relationship between the external disk temperature and the outdoor ambient temperature, that is, the higher the outdoor ambient temperature, the higher the external disk temperature, the first cooling threshold and the second cooling threshold can be determined according to the outdoor ambient temperature.

[0117] In a possible implementation, a cooling outdoor ambient temperature threshold may be set to determine the first cooling threshold and the second cooling threshold.

[0118] Optionally, the refrigeration outdoor environment temperature threshold may be determined according to actual application conditions. For example, the refrigeration outdoor environment temperature threshold may be set to 35°C.

[0119] Optionally, if the outdoor ambient temperature is less than the cooling ambient temperature threshold, it can be determined that the outdoor ambient temperature is low, and therefore the first cooling threshold and the second cooling threshold can be set relatively low. For example, when the outdoor ambient temperature is less than the cooling ambient temperature threshold, the value range of the first cooling threshold is 10°C to 15°C, and the range of the second cooling threshold is 0°C to 15°C. Then, the corresponding first cooling threshold and second cooling threshold can be determined in advance within the corresponding value range based on actual conditions, for example, the first cooling threshold is set to 10°C and the second cooling threshold is set to 2°C.

[0120] Optionally, if the outdoor ambient temperature is greater than or equal to the cooling ambient temperature threshold, it can be determined that the outdoor ambient temperature is high, and therefore the first cooling threshold and the second cooling threshold can be set relatively high. For example, when the outdoor ambient temperature is greater than or equal to the cooling ambient temperature threshold, the value range of the first cooling threshold is 10°C to 25°C, and the range of the second cooling threshold is 0°C to 15°C. Then, the corresponding first cooling threshold and second cooling threshold can be determined in advance within the corresponding value range based on actual conditions, for example, setting the first cooling threshold to 15°C and the second cooling threshold to 5°C.

[0121] It can be understood that the first cooling threshold when the outdoor ambient temperature is high should be greater than the first cooling threshold when the outdoor ambient temperature is low; the second cooling threshold when the outdoor ambient temperature is high should be greater than the second cooling threshold when the outdoor ambient temperature is low.

[0122] In addition, there is a certain linear relationship between the compressor current and the outdoor ambient temperature, that is, the higher the outdoor ambient temperature, the higher the compressor current. At the same time, since the external disk temperature can reflect the operating load condition of the air conditioner to a certain extent, the corresponding high cooling current difference and low cooling current difference can be determined comprehensively based on the outdoor ambient temperature and the external disk temperature.

[0123] Similarly, if the outdoor ambient temperature is lower than the cooling ambient temperature threshold, it can be determined that the outdoor ambient temperature is relatively low, so the cooling high temperature difference current and the cooling low temperature difference current can be set relatively low; if the outdoor ambient temperature is greater than or equal to the cooling ambient temperature threshold, it can be determined that the outdoor ambient temperature is relatively high, so the cooling high temperature difference current and the cooling low temperature difference current can be set relatively high.

[0124] In addition, since the operating load of the air conditioner is lower when the outside disk temperature is lower, the current value of the compressor will be larger than the current value when the outside disk temperature is higher. Therefore, the cooling high temperature difference current can be set relatively low when the outside disk temperature is higher, and the cooling low temperature difference current can be set relatively high when the outside disk temperature is lower.

[0125] In one possible implementation, after obtaining the outdoor ambient temperature, the air conditioner can first determine whether the outdoor ambient temperature is lower than a preset cooling outdoor ambient temperature threshold. If it is lower than the cooling outdoor ambient temperature threshold, it is determined that the outdoor ambient temperature is low at this time. Therefore, the first cooling threshold and the second cooling threshold that should be used as the basis for judgment can be determined to be thresholds set for the case where the outdoor ambient temperature is low, and the cooling high temperature difference current and the cooling low temperature difference current are determined to be current values ​​set for the case where the outdoor ambient temperature is low; if it is greater than or equal to the cooling outdoor ambient temperature threshold, it is determined that the outdoor ambient temperature is high at this time. Therefore, the first cooling threshold and the second cooling threshold that should be used as the basis for judgment can be determined to be thresholds set for the case where the outdoor ambient temperature is high, and the cooling high temperature difference current and the cooling low temperature difference current are determined to be current values ​​set for the case where the outdoor ambient temperature is high.

[0126] Optionally, the cooling high temperature difference current may include a first cooling high temperature difference current and a second cooling high temperature difference current. It can be understood that the first cooling high temperature difference current when the outdoor ambient temperature is relatively high should be greater than the first cooling high temperature difference current when the outdoor ambient temperature is relatively low; the second cooling high temperature difference current when the outdoor ambient temperature is relatively high should be greater than the second cooling high temperature difference current when the outdoor ambient temperature is relatively low.

[0127] Optionally, if the outdoor ambient temperature is low, the value range of the first refrigeration high temperature differential current can be 1°C to 1.15°C, and the value range of the second refrigeration high temperature differential current can be 0.7°C to 1.1°C. The corresponding first refrigeration high temperature differential current and second refrigeration high temperature differential current can be determined in advance within the corresponding value range according to actual conditions, for example, the first refrigeration high temperature differential current is set to 1.1°C and the second refrigeration high temperature differential current is set to 0.85°C.

[0128] Optionally, if the outdoor ambient temperature is high, the value range of the first refrigeration high temperature differential current can be 1.1°C to 1.3°C, and the value range of the second refrigeration high temperature differential current can be 0.8°C to 1.2°C. The corresponding first refrigeration high temperature differential current and second refrigeration high temperature differential current can be determined in advance within the corresponding value range according to actual conditions, for example, the first refrigeration high temperature differential current is set to 1.2°C and the second refrigeration high temperature differential current is set to 0.9°C.

[0129] In this embodiment, the air conditioner can determine the current operating state of the air conditioner specifically according to the compressor current, the first cooling high temperature difference current, and the second cooling high temperature difference current.

[0130] Specifically, determining the current operating state of the air conditioner according to the compressor current and the cooling high temperature difference current in step S21-4 can be achieved by the following steps:

[0131] If the compressor current is greater than or equal to the first refrigeration high temperature difference current, it is determined that the air conditioner is in an abnormal compressor state or a dirty and blocked condenser state; if the compressor current is less than or equal to the second refrigeration high temperature difference current, it is determined that the air conditioner is in a liquid shortage state; if the compressor current is greater than the second refrigeration high temperature difference current and less than the first refrigeration high temperature difference current, it is determined that the air conditioner is in a normal state.

[0132] Optionally, if the compressor current is greater than or equal to the first refrigeration high temperature difference current, it can be determined that the air conditioner has abnormal heat dissipation, and the quality and flow of the refrigerant liquid are relatively large, so there may be an abnormal compressor condition or a dirty condenser condition.

[0133] Optionally, the air conditioner may notify the user that the air conditioner may be in an abnormal compressor state or a dirty condenser blockage state when the compressor current is greater than or equal to the first cooling high temperature difference current.

[0134] Optionally, if the compressor current is less than or equal to the second cooling high temperature difference current, it can be determined that the refrigerant liquid flow in the air conditioner is small at this time, and therefore there may be a liquid shortage condition.

[0135] Optionally, the air conditioner may notify the user that the air conditioner may be in a liquid shortage state when the compressor current is less than or equal to the second cooling high temperature difference current.

[0136] Optionally, if the compressor current is greater than the second cooling high temperature difference current and less than the first cooling high temperature difference current, it can be determined that the air conditioner is operating normally at this time.

[0137] Optionally, the refrigeration low-temperature differential current may include a first refrigeration low-temperature differential current and a second refrigeration low-temperature differential current. It can be understood that the first refrigeration low-temperature differential current when the outdoor ambient temperature is relatively high should be greater than the first refrigeration low-temperature differential current when the outdoor ambient temperature is relatively low; the second refrigeration low-temperature differential current when the outdoor ambient temperature is relatively high should be greater than the second refrigeration low-temperature differential current when the outdoor ambient temperature is relatively low.

[0138] Optionally, if the outdoor ambient temperature is low, the value range of the first refrigeration low temperature differential current can be 1.1°C to 1.3°C, and the value range of the second refrigeration low temperature differential current can be 0.8°C to 1.1°C. The corresponding first refrigeration low temperature differential current and second refrigeration low temperature differential current can be determined in advance within the corresponding value range according to actual conditions, for example, the first refrigeration low temperature differential current is set to 1.2°C and the second refrigeration low temperature differential current is set to 0.95°C.

[0139] Optionally, if the outdoor ambient temperature is high, the value range of the first refrigeration low temperature differential current can be 1.2°C to 1.4°C, and the value range of the second refrigeration low temperature differential current can be 0.9°C to 1.2°C. The corresponding first refrigeration low temperature differential current and second refrigeration low temperature differential current can be determined in advance within the corresponding value range according to actual conditions, for example, the first refrigeration low temperature differential current is set to 1.3°C and the second refrigeration low temperature differential current is set to 1°C.

[0140] In this embodiment, the air conditioner can determine the current operating state of the air conditioner specifically according to the compressor current, the first refrigeration low temperature difference current, and the second refrigeration low temperature difference current.

[0141] Specifically, determining the current operating state of the air conditioner according to the compressor current and the cooling low temperature difference current in step S21-5 can be achieved by the following steps:

[0142] If the compressor current is greater than or equal to the first refrigeration low temperature difference current, it is determined that the air conditioner is in an abnormal compressor state; if the compressor current is less than or equal to the second refrigeration low temperature difference current, it is determined that the air conditioner is in an evaporator dirty and blocked state; if the compressor current is greater than the second refrigeration low temperature difference current and less than the first refrigeration low temperature difference current, it is determined that the air conditioner is in a normal state.

[0143] Optionally, if the compressor current is greater than or equal to the first refrigeration low temperature difference current, it can be determined that the air conditioner has abnormal heat dissipation at this time, and the quality and flow rate of the refrigerant liquid are relatively large, but because the external disk temperature is relatively low at this time, the air conditioner may have an abnormal compressor.

[0144] Optionally, the air conditioner may notify the user that the air conditioner may be in an abnormal compressor state when the compressor current is greater than or equal to the first refrigeration low temperature difference current.

[0145] Optionally, if the compressor current is less than or equal to the second cooling low temperature difference current, it can be determined that the heat exchange of the indoor unit of the air conditioner is poor at this time, and therefore the evaporator may be dirty and blocked.

[0146] Optionally, the air conditioner may notify the user that the air conditioner may be in an evaporator dirty and blocked state when the compressor current is less than or equal to the second refrigeration low temperature difference current.

[0147] Optionally, if the compressor current is greater than the second refrigeration low temperature difference current and less than the first refrigeration low temperature difference current, it can be determined that the air conditioner is operating normally at this time.

[0148] In this embodiment, since the operating load of the air conditioner is lower when the outer disk temperature is relatively low, the current value of the compressor will accordingly be larger than the current value when the outer disk temperature is relatively high. Therefore, the first refrigeration low temperature difference current should be greater than the first refrigeration high temperature difference current, and the second refrigeration low temperature difference current should be greater than the second refrigeration high temperature difference current.
