[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0027] The embodiments of the present application provide a control method and device of an air conditioner, an air conditioner, an electronic device and a storage medium, so that the air conditioner can obtain a substitute temperature of a temperature sensor when the temperature sensor fails, and continue to run based on the substitute temperature, thereby improving user experience. The following will be described with reference to the drawings.

[0028] Please refer to Figure 1 , Figure 1 A first flowchart of a control method of an air conditioner provided in an embodiment of the present application is provided.

[0029] The embodiments of the present application provide a control method of 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 with the first indoor unit.

[0030] The air conditioner provided in the embodiments of the present application can be a multi-split air conditioner, that is, one outdoor unit is connected with multiple indoor units, or a single-split air conditioner, that is, one outdoor unit is connected with 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 can further include a throttling expansion valve connected to the first heat exchanger through a pipeline in which refrigerant is arranged, and capable of controlling the flow of the refrigerant. Generally, the greater the opening degree of the throttling expansion valve, the greater the flow of refrigerant in the pipeline, and the greater the heat exchange capacity of the first heat exchanger. The smaller the opening degree of the throttling expansion valve, the smaller the flow of refrigerant, and the smaller the heat exchange capacity of the first heat exchanger.

[0033] The first heat exchanger can be an evaporator, and the principle of refrigeration of the evaporator is to use the characteristic that liquid low-temperature refrigerant (refrigerant) is easy to absorb heat to change into a gaseous state at 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 control method of the air conditioner includes the following steps.

[0036] S20, when it is detected that the first temperature sensor and / or the second temperature sensor fails, setting the temperature sensor that fails as a target temperature sensor.

[0037] The fault detection of the temperature sensor can be obtained directly by the first temperature sensor and / or the second temperature sensor reporting an error, or can be obtained by the data measured by the first temperature sensor and / or the second temperature sensor.

[0038] In the embodiments of the present application, the states of the first temperature sensor and the second temperature sensor can be monitored at the same time. The types of failure of the first temperature sensor and / or the second temperature sensor can be that the first temperature sensor and / or the second temperature sensor is not electrically connected, for example, is not electrically connected to the processor (control terminal); the first temperature sensor and / or the second temperature sensor is 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 is installed in a wrong position or the wiring terminal is inserted in reverse.

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

[0040] S40, obtaining 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 can be a temperature detected by a temperature sensor of similar structure in another indoor unit, or a temperature detected by another temperature sensor in the first indoor unit.

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

[0043] S60, continue to operate the air conditioner 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 has been in a fault state, in order not to affect the continued operation of the air conditioner, a replacement temperature matching the current working mode is obtained, the temperature detected by the temperature sensor is replaced by the replacement temperature, and then the air conditioner is controlled to continue to operate according to the replacement temperature and the temperature detected by the other temperature sensor that has not failed, thereby avoiding the shutdown of the air conditioner caused by the failure of the temperature sensor, realizing the self-repairing function, maintaining the continued operation of the air conditioner, and improving the user experience.

[0045] In some embodiments, please refer to Figure 2 , Figure 2 A second flowchart of the control method of the air conditioner provided in the embodiments of the present application is shown. In the step of detecting that the first temperature sensor and / or the second temperature sensor has failed, the control method of the air conditioner comprises: 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 has failed.

[0046] In the case that the first temperature sensor and / or the second temperature sensor is not connected to the processor (control terminal) or the first temperature sensor and / or the second temperature sensor is damaged, the air conditioner will generally appear a fault prompt after power-on, so in some cases, when the air conditioner appears a corresponding fault prompt or cannot operate due to the failure to receive information of the first temperature sensor and / or the second temperature sensor, it can be determined that the first temperature sensor and / or the second temperature sensor is not electrically connected, for example, is 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, please refer to Figure 3 , Figure 3 A third flowchart of the control method of the air conditioner provided in the embodiments of the present application is shown. In the step of detecting that the first temperature sensor and / or the second temperature sensor has failed, the control method of the air conditioner comprises: S12, when the temperature detected by the first temperature sensor and / or the second temperature sensor does not decrease with the extension of the working time of the air conditioner, it is determined that the first temperature sensor and / or the second temperature sensor has failed.

[0048] In normal cases, with the air conditioner being turned on, the actual inlet / outlet pipe temperature will decrease, the heat exchanger temperature will become lower and lower, and the opening degree of the throttling expansion valve will also become lower and lower. When the first temperature sensor and / or the second temperature sensor is installed at an unreasonable position, 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 change range of the inlet / outlet pipe temperature detected by the first temperature sensor and / or the second temperature sensor is small or even unchanged, and thus it is determined that the installation position of the indoor inlet / outlet pipe sensor is unreasonable.

[0049] In some embodiments, referring to Figure 4 , Figure 4 A fourth flowchart of the control method of the air conditioner provided in the embodiments of the present application is shown. In the step of detecting that the first temperature sensor and / or the second temperature sensor fails, the control method of the air conditioner comprises: 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 the first temperature sensor and the second temperature sensor both fail.

[0050] In normal cases, the refrigerant flows from the refrigerant inlet pipe of the first heat exchanger to the refrigerant outlet pipe, and the inlet pipe temperature is often lower than the outlet pipe temperature. When the first temperature sensor and / or the second temperature sensor is inserted reversely (the connection is in wrong position), the detected inlet pipe temperature will be maintained to be greater than the outlet pipe temperature, which causes the throttling expansion valve of the first indoor unit to be maintained at a very low opening degree or even at the minimum opening degree, thereby affecting the refrigeration effect of the first indoor unit. If the inlet pipe temperature of other indoor units is lower than the outlet pipe temperature, it can be determined that the first temperature sensor and / or the second temperature sensor of the first indoor unit both fail, i.e., the installation is in wrong position or the connection terminal is inserted reversely.

[0051] In the above, the first indoor unit is taken as an example to illustrate various cases of the temperature sensor failure of the air conditioner in the embodiments of the present application.

[0052] In the embodiments of the present application, when it is detected that the first temperature sensor and / or the second temperature sensor fails, the air conditioner will remind the user that the failure will affect the use of related functions and should be repaired as soon as possible. At this time, the whole machine cannot be stopped for processing, and the temperature detected by the target temperature sensor can be replaced by finding a replacement inlet / outlet pipe temperature to repair the first temperature sensor and / or the second temperature sensor, so as to avoid the stoppage due to the failure of the first temperature sensor and / or the second temperature sensor, and ensure that the air conditioner continues to operate in a short time and does not affect 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, i.e., the first temperature sensor and / or the second temperature sensor is installed incorrectly or the wiring terminal is inserted reversely, according to the replacement temperature of the target temperature sensor, the control method of the air conditioner comprises: 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, i.e., the inlet / outlet pipe temperature is reversed.

[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 maintain the minimum opening degree, so that the air conditioning cooling effect is not obvious. For example, if the temperature detected by the first temperature sensor is greater than the temperature detected by the second temperature sensor for 10 to 20 minutes, it can be determined that the first temperature sensor and the second temperature sensor are installed incorrectly or the wiring terminal is inserted reversely. At this time, the inlet / outlet pipe temperature is reversed, i.e., 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, so as to ensure that the air conditioner continues to run in a short time and does not affect the user experience.

[0055] In order to further determine, 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 less than the outlet pipe temperature, it is more evidence that the first temperature sensor and the second temperature sensor of the first indoor unit are installed incorrectly or the wiring terminal is inserted reversely.

[0056] In other cases, the air conditioner further comprises a second indoor unit connected with the outdoor unit, the second indoor unit comprising a second heat exchanger and a plurality of third temperature sensors for detecting 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 can be understood 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 be in the refrigeration state. In the case that the working state of the second indoor unit is good, the first temperature sensor and / or the second temperature sensor in the first indoor unit find the corresponding temperature sensor in the second indoor unit, for example, the first temperature sensor corresponds to the third temperature sensor in the second indoor unit for detecting the inlet pipe temperature of the second heat exchanger, and the second temperature sensor corresponds to the third temperature sensor in the second indoor unit for detecting the outlet pipe temperature of the second heat exchanger. If the first temperature sensor and / or the second temperature sensor is damaged, the temperature detected by the corresponding temperature sensor of the second indoor unit can be selected.

[0058] In other cases, the first indoor unit further comprises a fourth temperature sensor for detecting the middle pipe temperature of the first heat exchanger. The replacement temperature is the middle pipe temperature detected by the fourth sensor. Especially 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 pipe temperature detected by the fourth temperature sensor replaces the temperature detected by the first temperature sensor, and then the air conditioner continues to run according to the temperatures detected by the fourth temperature sensor and the second temperature sensor.

[0059] In some scenarios, please refer to Figure 5 , Figure 5 The fifth flowchart of the control method of the air conditioner provided by the embodiment of the application is provided. In the control method in the embodiment of the application, it is judged that the running mode of the air conditioner is the refrigeration mode. If not, the flow is ended; if yes, in the refrigeration mode, it is judged whether the first temperature sensor and / or the second temperature sensor appears the fault of being not electrically connected or the first temperature sensor and / or the second temperature sensor is damaged. If yes, the user is prompted to appear the fault of the first temperature sensor and / or the second temperature sensor being damaged, not connected or damaged; if not, the inlet / outlet pipe temperature will be continuously detected. By comparing the inlet / outlet pipe temperature before starting and the inlet / outlet pipe temperature after starting once or multiple times, the temperature change of the inlet / outlet pipe temperature is determined, if the temperature change is very small or almost none, it is determined that the installation position of the inlet / outlet pipe sensor is unreasonable. If the temperature difference exists normal change, and the refrigerant amount is normal, it is judged whether the inlet pipe temperature is always greater than the outlet pipe temperature, if yes, it is determined that the first temperature sensor and / or the second temperature sensor appears the fault of being installed in wrong position or the wiring terminal being inserted reversely. Subsequently, the detection is returned to the initial step to monitor the condition of the first temperature sensor and / or the second temperature sensor at any time.

[0060] Please refer to Figure 6 , Figure 6The sixth flowchart of the control method of the air conditioner provided in the embodiments of the present application is shown in FIG. 6. When it is determined that the first temperature sensor and / or the second temperature sensor is installed in a wrong position or the terminal is inserted reversely, the inlet / outlet pipe temperature can be adjusted. When the first temperature sensor and / or the second temperature sensor is not electrically connected, or the first temperature sensor and / or the second temperature sensor is damaged, or the installation position of the inlet / outlet pipe sensor is unreasonable, it is determined whether the number of the indoor units of the air conditioner is greater than a preset number of indoor units, such as 1. If the number of the indoor units is 1, the indoor unit is only the first indoor unit, and the fourth temperature sensor can be used to replace the first temperature sensor or the second temperature sensor, and the air conditioner continues to operate according to the inlet pipe temperature detected by the fourth temperature sensor. If the number of the indoor units is greater than 1, a normal target indoor unit, such as the second indoor unit, is determined from the other indoor units, and the inlet / outlet pipe temperature of the second indoor unit is collected to replace the inlet / outlet pipe temperature 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, 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.

[0062] In the above scenario, when the number of the indoor units is greater than 1, the fourth temperature sensor can be used to replace the first temperature sensor or the second temperature sensor, and the air conditioner continues to operate according to the temperature detected by the fourth temperature sensor.
