[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0027] The embodiments of the present application provide a control method, device, air conditioner, electronic device and storage medium for an air conditioner, so that when a temperature sensor fails, the air conditioner can obtain an alternative temperature of the temperature sensor, and maintain the air conditioner to continue to operate based on the alternative temperature, thereby improving the user experience. The following is an explanation with reference to the accompanying drawings.

[0028] See also Figure 1 , Figure 1 A first flow chart of the air conditioner control method provided in an embodiment of the present application.

[0029] The embodiment of the present application provides a control method for an air conditioner, which is applied to an air conditioner. The air conditioner includes an outdoor unit and a first indoor unit, and the outdoor unit is connected to the first indoor unit.

[0030] The air conditioner provided in the embodiment of the present application can be a multi-split air conditioner, that is, one outdoor unit is connected to multiple indoor units, or it can be a single-split air conditioner, that is, one outdoor unit is connected to one indoor unit.

[0031] The first indoor unit includes a first heat exchanger, a first temperature sensor and a second temperature sensor. The first temperature sensor is used to detect the outlet temperature of the first heat exchanger, and the second temperature sensor is used to detect the outlet temperature of the first heat exchanger.

[0032] The first indoor unit may further include a throttling expansion valve, which is connected to the first heat exchanger via a pipeline, in which a refrigerant is arranged, and the throttling expansion valve can control the flow of the refrigerant. Generally, the larger the opening of the throttling expansion valve, the larger the flow of the refrigerant in the pipeline, and the heat exchange capacity of the first heat exchanger is enhanced accordingly, and the smaller the opening of the throttling expansion valve, the smaller the flow of the refrigerant flowing through, and the heat exchange capacity of the first heat exchanger is reduced accordingly.

[0033] The first heat exchanger can be an evaporator. The refrigeration principle of the evaporator is to use the characteristics of liquid low-temperature refrigerant (refrigerant) to easily absorb heat and transform into gas under low pressure, and then the refrigerant absorbs the heat of the cooled medium to achieve the purpose of refrigeration.

[0034] The first temperature sensor can be arranged on the refrigerant inlet pipe of the first heat exchanger to detect the temperature of the refrigerant at the inlet of the first heat exchanger. The second temperature sensor can be arranged on the refrigerant outlet pipe of the first heat exchanger to detect the temperature of the refrigerant at the outlet of the first heat exchanger.

[0035] The air conditioner control method includes the following steps.

[0036] S20: When it is detected that the first temperature sensor and / or the second temperature sensor fails, the failed temperature sensor is set as a target temperature sensor.

[0037] Fault detection of the temperature sensor may be obtained through direct error reporting of the first temperature sensor and / or the second temperature sensor, or may be obtained through data measured by the first temperature sensor and / or the second temperature sensor.

[0038] In the embodiment of the present application, the status of the first temperature sensor and the second temperature sensor can be monitored simultaneously. The types of failure of the first temperature sensor and / or the second temperature sensor can be: the first temperature sensor and / or the second temperature sensor are not electrically connected, for example, not electrically connected to the processor (control terminal); the first temperature sensor and / or the second temperature sensor are damaged; the installation position of the first temperature sensor and / or the second temperature sensor is unreasonable; the first temperature sensor and / or the second temperature sensor are installed in a misplaced position or the wiring terminal is plugged in reverse.

[0039] The target temperature sensor may be only the first temperature sensor or the second temperature sensor, or may be both the first temperature sensor and the second temperature sensor.

[0040] S40: Obtain a replacement temperature of the target temperature sensor.

[0041] In some cases, when the air conditioner is a multi-split air conditioner, the replacement temperature may be a temperature detected by a temperature sensor of a similar structure in other indoor units, or a temperature detected by other temperature sensors in the first indoor unit.

[0042] In other cases, when the air conditioner is a single-split air conditioner, the replacement temperature may be a temperature detected by other temperature sensors in the first indoor unit.

[0043] S60: Control the air conditioner to continue operating according to the replacement temperature.

[0044] Since it is detected that the first temperature sensor and / or the second temperature sensor on the first heat exchanger is in a faulty state, in order not to affect the continued operation of the air conditioner, an alternative temperature matching the current working mode is obtained, and the alternative temperature is used to replace the temperature detected by the temperature sensor. The air conditioner is then controlled to continue operating according to the alternative temperature and the temperatures detected by other temperature sensors that have not failed, thereby avoiding shutdown of the air conditioner due to failure of the temperature sensor, realizing the self-repair function, maintaining the continued operation of the air conditioner, and improving the user experience.

[0045] In some embodiments, see Figure 2 , Figure 2 A second flow chart of the air conditioner control method provided in an embodiment of the present application. In the step of detecting that the first temperature sensor and / or the second temperature sensor is faulty, the air conditioner control method includes: S11, when the first temperature sensor and / or the second temperature sensor cannot detect the temperature, it is determined that the first temperature sensor and / or the second temperature sensor is faulty.

[0046] When the first temperature sensor and / or the second temperature sensor are not connected to the processor (control terminal), or the first temperature sensor and / or the second temperature sensor are damaged, the air conditioner will generally display a fault prompt after power-on. Therefore, in some cases, when the air conditioner displays a corresponding fault prompt or cannot receive information from the first temperature sensor and / or the second temperature sensor and cannot operate, it can be determined that the first temperature sensor and / or the second temperature sensor are not electrically connected, for example, are not electrically connected to the processor (control terminal), or the first temperature sensor and / or the second temperature sensor is damaged.

[0047] In some embodiments, see Figure 3 , Figure 3 A third flow chart of the air conditioner control method provided in an embodiment of the present application. In the step of detecting that the first temperature sensor and / or the second temperature sensor is faulty, the air conditioner control method includes: S12, if the temperature detected by the first temperature sensor and / or the second temperature sensor does not decrease as the air conditioner working time increases, it is determined that the first temperature sensor and / or the second temperature sensor is faulty.

[0048] Under normal circumstances, as the air conditioner is turned on, the actual inlet / outlet pipe temperature will decrease, the heat exchanger temperature will become lower and lower, and the opening of the throttling expansion valve will become lower and lower. When the installation position of the first temperature sensor and / or the second temperature sensor is unreasonable, the inlet / outlet pipe temperature detected by the first temperature sensor and / or the second temperature sensor is inconsistent with the actual inlet / outlet pipe temperature. The variation range of the inlet / outlet pipe temperature detected by the first temperature sensor and / or the second temperature sensor is small or even unchanged, so it is judged that the installation position of the indoor inlet / outlet pipe sensor is unreasonable.

[0049] In some embodiments, see Figure 4 , Figure 4 A fourth flow chart of the air conditioner control method provided in an embodiment of the present application. In the step of detecting that the first temperature sensor and / or the second temperature sensor is faulty, the air conditioner control method includes: S13, when the temperature detected by the first temperature sensor is greater than the temperature detected by the second temperature sensor, it is determined that both the first temperature sensor and the second temperature sensor are faulty.

[0050] Under normal circumstances, the refrigerant flows from the refrigerant inlet pipe of the first heat exchanger through the refrigerant outlet pipe, and the inlet temperature is often lower than the outlet temperature. When the first temperature sensor and / or the second temperature sensor are plugged in reverse (connected misplaced), the detected inlet temperature will remain higher than the outlet temperature, which will cause the throttling expansion valve of the first indoor unit to remain very low or even maintained at the minimum opening, affecting the cooling effect of the first indoor unit. If the inlet temperature of other indoor units is lower than the outlet temperature, it can be judged that the first temperature sensor and / or the second temperature sensor of the first indoor unit are both faulty, that is, the installation is misplaced or the wiring terminals are plugged in reverse.

[0051] In the above, the first indoor unit is taken as an example in the embodiment of the present application to illustrate various situations in which the temperature sensor of the air conditioner fails.

[0052] In an embodiment of the present application, when a fault is detected in the first temperature sensor and / or the second temperature sensor, the air conditioner will remind the user that this fault will affect the use of related functions and that the air conditioner should be reported for repair as soon as possible. At this time, the entire machine cannot be shut down for processing. The temperature detected by the target temperature sensor can be replaced by finding a replacement inlet / outlet pipe temperature to self-repair the first temperature sensor and / or the second temperature sensor, thereby avoiding shutdown due to a fault in the first temperature sensor and / or the second temperature sensor, and ensuring that the air conditioner continues to operate in a short period of time without affecting the user experience.

[0053] In some cases, when the temperature detected by the first temperature sensor is greater than the temperature detected by the second temperature sensor, that is, the first temperature sensor and / or the second temperature sensor are installed misplaced or the wiring terminals are plugged in reverse, based on obtaining the replacement temperature of the target temperature sensor, the control method of the air conditioner includes: the replacement temperature of the first temperature sensor is the temperature detected by the second temperature sensor, and the replacement temperature of the second temperature sensor is the temperature detected by the first temperature sensor, that is, the inlet / outlet pipe temperatures are swapped.

[0054] In some scenarios, in the first indoor unit, when the temperature detected by the first temperature sensor is continuously greater than the temperature detected by the second temperature sensor, the throttling expansion valve will remain very low or even maintained at the minimum opening, making the air conditioning cooling effect unobvious. For example, if the temperature detected by the first temperature sensor is greater than the temperature detected by the second temperature sensor within 10 to 20 minutes, it can be determined that the first temperature sensor and the second temperature sensor are installed in a misaligned position or the wiring terminals are plugged in reverse. At this time, the outlet / pipe temperatures are swapped, that is, the replacement temperature of the first temperature sensor is the temperature detected by the second temperature sensor, and the replacement temperature of the second temperature sensor is the temperature detected by the first temperature sensor, to ensure that the air conditioner continues to run in a short period of time without affecting the user experience.

[0055] For further judgment, when the air conditioner is a multi-split air conditioner, the difference between the inlet pipe temperature and the outlet pipe temperature of the second indoor unit can also be detected. If the inlet pipe temperature of the second indoor unit is lower than the outlet pipe temperature, it further proves that the first temperature sensor and the second temperature sensor of the first indoor unit are misaligned or the wiring terminals are plugged in reverse.

[0056] In other cases, the air conditioner further includes a second indoor unit, the second indoor unit is connected to the outdoor unit, the second indoor unit includes a second heat exchanger and a plurality of third temperature sensors, the plurality of third temperature sensors are used to detect the inlet pipe temperature and the outlet pipe temperature of the second heat exchanger. When the target temperature sensor is the first temperature sensor, the replacement temperature is the inlet pipe temperature detected by the third temperature sensor, and when the target temperature sensor is the second temperature sensor, the replacement temperature is the outlet pipe temperature detected by the third temperature sensor.

[0057] It is understandable that the first indoor unit and the second indoor unit should have the same refrigeration principle, and the first indoor unit and the second indoor unit can both be in a refrigeration state. When the second indoor unit is in good working condition, the first temperature sensor and / or the second temperature sensor in the first indoor unit can find corresponding temperature sensors in the second indoor unit. For example, the first temperature sensor corresponds to the third temperature sensor in the second indoor unit that detects the inlet temperature of the second heat exchanger, and the second temperature sensor corresponds to the third temperature sensor in the second indoor unit that detects the outlet temperature of the second heat exchanger. If the first temperature sensor and / or the second temperature sensor is damaged, the temperature detected by the temperature sensor corresponding to the second indoor unit can be selected.

[0058] In other cases, the first indoor unit further includes a fourth temperature sensor, which is used to detect the middle tube temperature of the first heat exchanger. The replacement temperature is the middle tube temperature detected by the fourth sensor. In particular, when the first temperature sensor or the second temperature sensor fails, the temperature detected by the fourth temperature sensor can be used to replace the temperature detected by the failed temperature sensor. For example, when the first temperature sensor fails, the middle tube temperature detected by the fourth temperature sensor replaces the temperature detected by the first temperature sensor, and the air conditioner continues to operate according to the temperatures detected by the fourth temperature sensor and the second temperature sensor.

[0059] In some cases, see Figure 5 , Figure 5 A fifth flow chart of the control method of the air conditioner provided in the embodiment of the present application. In the control method in the embodiment of the present application, it is determined that the operating mode of the air conditioner is the cooling mode. If not, the process is terminated; if so, in the cooling mode, it is determined whether the first temperature sensor and / or the second temperature sensor are not electrically connected, or the first temperature sensor and / or the second temperature sensor are damaged. If so, the user is prompted that the first temperature sensor and / or the second temperature sensor are damaged, not connected or damaged; if not, the inlet / outlet pipe temperature will continue to be detected. By comparing the inlet / outlet pipe temperature before startup and the inlet / outlet pipe temperature after startup once or more, the temperature change of the inlet / outlet pipe temperature is determined. If the temperature change is small or almost non-existent, it is determined that the installation position of the inlet / outlet pipe sensor is unreasonable. If the temperature difference has a normal change and the amount of refrigerant is normal, it is determined whether the inlet pipe temperature is always greater than the outlet pipe temperature. If so, it is determined that the first temperature sensor and / or the second temperature sensor are installed in a misplaced position or the wiring terminal is plugged in the opposite direction. Subsequently, return to the initial step for detection to monitor the situation of the first temperature sensor and / or the second temperature sensor at any time.

[0060] See also Figure 6 , Figure 6A sixth flow chart of the control method of the air conditioner provided in the embodiment of the present application. When it is determined that the first temperature sensor and / or the second temperature sensor are installed in a misplaced position or the wiring terminal is plugged in reverse, the inlet / outlet pipe temperature can be swapped. When the first temperature sensor and / or the second temperature sensor are not electrically connected, or the first temperature sensor and / or the second temperature sensor are damaged, or the installation position of the inlet / outlet pipe sensor is unreasonable, it is determined whether the number of indoor units of the air conditioner is greater than the preset number of indoor units, such as the preset number 1. If the number of indoor units is 1, the indoor unit of the air conditioner is only the first indoor unit. At this time, the first temperature sensor or the second temperature sensor can be replaced by the fourth temperature sensor, and the air conditioner is controlled to continue to operate according to the middle pipe temperature detected by the fourth temperature sensor. If the number of indoor units is greater than 1, a normal target indoor unit, such as the second indoor unit, is determined from other indoor units, and the inlet / outlet pipe temperatures of other indoor units are collected, and the collected inlet / outlet pipe temperatures of the second indoor unit are replaced with the inlet / outlet pipe temperatures of the first indoor unit.

[0061] When the target temperature sensor is the first temperature sensor, the replacement temperature is the inlet pipe temperature detected by the third temperature sensor; when the target temperature sensor is the second temperature sensor, the replacement temperature is the outlet pipe temperature detected by the third temperature sensor.

[0062] In the above scenario, when the number of indoor units is greater than 1, other indoor units may not be used, and the fourth temperature sensor may be used to replace the first temperature sensor or the second temperature sensor to control the air conditioner to continue operating according to the temperature detected by the fourth temperature sensor.
