Regarding the implementation subject of the method of the embodiment of the present application, it can be a variety of processors or controllers with processing capabilities or computing capabilities, and can be set in an air-conditioning terminal, such as an outdoor unit, through local processing of data, and can also Integrate data communication with the server to control the smooth operation of the air conditioner when the power supply voltage of the air conditioner fluctuates, optimize the air conditioning effect and save the consumption of power resources.

As shown in Figure 3, in step S310, the power supply voltage of the air conditioner is obtained.

In step S320, it is detected whether the power supply voltage of the air conditioner is lower than a preset voltage threshold.

Here, the voltage threshold can be set according to the power supply voltage of the local mains power grid, for example, the mains voltage in China is 220V, and the mains voltage in Japan is 110V. In some embodiments, when the air conditioner receives a power-on command, the air conditioner can detect the power supply voltage to identify whether the power supply voltage is too low, and promptly detect the low-voltage operating condition of the air conditioner.

In step S330, when the power supply voltage is not lower than the voltage threshold, a first control signal is sent to control the refrigerant fluid to be connected from the compressor of the air conditioner to the radiator of the air conditioner through the first refrigerant pipeline.

In step S340, when the power supply voltage is lower than the voltage threshold, a second control signal is sent to control the refrigerant fluid to be connected from the compressor to the radiator through the second refrigerant pipeline or the first refrigerant pipeline, and the first refrigerant pipeline is connected to the radiator. The first refrigerant contact area between the radiators is smaller than the second refrigerant contact area between the second refrigerant pipeline and the radiator.

Combined with the example in FIG. 2 , switching from the first refrigerant pipeline 221 to the second refrigerant pipeline 223 is achieved by generating a valve control signal for the valve 240 .

Through the embodiments of the present application, when it is detected that the power supply voltage of the air conditioner is reduced, the refrigerant pipeline with a larger refrigerant contact area is switched to optimize the air conditioning effect to a certain extent, and under the same external temperature environment or indoor and outdoor temperature difference conditions, it is possible to Effectively reduce the workload of the compressor system and save the power consumed by the air conditioner.

Figure 4 shows a structural block diagram of the first refrigerant pipeline and the second refrigerant pipeline for switching according to an embodiment of the present application.

As shown in Figure 4, the refrigerant circuit of the air conditioner includes a main refrigerant pipeline 410 that connects the radiator and the compressor, bypass branches 420 and 430 connected in parallel with the main refrigerant pipeline 410, the main refrigerant pipeline 410 and the bypass branch. 420 and 430 are used to communicate with the radiator and the compressor respectively, and the reversing valve 440 (for example, a dredge valve can be used) is used to control the refrigerant fluid in the pipeline to flow in the first fluid direction or the second fluid direction. Corresponding one-way valves 421 and 431 are respectively provided on the branch passages 420 and 430 to conduct the first fluid direction (direction of the arrow in Figure 4) and block the second fluid direction (for example, corresponding to the arrow in Figure 4 opposite direction).

Specifically, when it is detected that the mains voltage is normal and it is necessary to use the first refrigerant pipeline with a smaller refrigerant contact area, the refrigerant fluid is controlled to flow in the second fluid direction based on the reversing valve 440 so that the refrigerant fluid can only flow from the air conditioner. The compressor is connected to the radiator through the main refrigerant pipeline 410 and cannot pass through the bypass branches 420 and 430 corresponding to the cut-off state. In addition, when a decrease in the mains voltage is detected and a second refrigerant pipeline corresponding to a larger refrigerant contact area needs to be used, the refrigerant fluid is controlled to flow in the first fluid direction based on the reversing valve 440 so that the refrigerant fluid passes through the compressor of the air conditioner. The main refrigerant pipeline and each bypass branch are connected to the radiator, thereby increasing the refrigerant contact area with the heat exchanger under low-voltage and frequency-limited working conditions.

Figure 5 shows a schematic diagram of the appearance of the refrigerant circuit of the air conditioner outdoor unit according to an embodiment of the present application.

As shown in Figure 5, the refrigerant circuit of the air-conditioning outdoor unit includes a main refrigerant pipeline 510, a dredge valve (not shown) for controlling the flow direction of the refrigerant, and at least one bypass branch 520, which is provided with a useful A one-way valve that conducts refrigerant in a specific fluid direction (arrow direction in Figure 5).

In some embodiments, when it is detected that the power supply voltage value of the air conditioner is normal, the dredge valve is controlled so that the refrigerant flows out of the interface 511 and exchanges heat with the radiator through the main refrigerant pipeline 510 . In addition, when an abnormality in the power supply voltage of the air conditioner is detected, the dredge valve is controlled so that the refrigerant flows out of the interface 513 and exchanges heat with the radiator through the main refrigerant pipeline 510 and the bypass branch 520 .

FIG. 6 shows a flow chart of an example of an air conditioning operation control method according to an embodiment of the present application.

As shown in Figure 6, in step S610, when it is determined that the power supply voltage is lower than the voltage threshold, the outdoor ambient temperature is compared with the preset temperature threshold. The outdoor ambient temperature is the temperature of the environment where the outdoor unit of the air conditioner is located.

In step S621, if it is determined that the outdoor ambient temperature is greater than the temperature threshold, a second pipeline control signal is sent so that the refrigerant fluid is connected from the compressor to the radiator through the second refrigerant pipeline.

In step S623, if it is determined that the outdoor ambient temperature is less than or equal to the temperature threshold, a first pipeline control signal is sent so that the refrigerant fluid is connected from the compressor to the radiator through the first refrigerant pipeline.

It should be noted that when the outdoor ambient temperature is too high, for example, over 48°C, and under low-pressure and high-temperature conditions, the compressor is more likely to enter the frequency-limited working state, resulting in poor cooling effect of the air conditioner and increasing the workload of the compressor system. , resulting in poor air conditioning effect and higher air conditioning electricity bills. Through the embodiments of this application, when it is detected that the power supply voltage of the air conditioner is low, it is identified whether the ambient temperature is too high. When the ambient temperature is too high, the control is switched to a refrigerant pipeline with a higher refrigerant contact area for refrigeration and optimization.

FIG. 7 shows a flow chart of an example of an air conditioning operation control method according to an embodiment of the present application.

In step S710, it is detected whether the power supply voltage of the air conditioner is lower than a preset voltage threshold.

In step S723, when the power supply voltage is lower than the voltage threshold, a second compressor control signal is sent so that the compressor operates at the second initial compressor frequency, so that the refrigerant fluid is connected from the compressor to the air conditioner through the second refrigerant pipeline. radiator, the second initial compressor frequency is greater than the first initial compressor frequency.

In some embodiments, before the air conditioner is started, the power supply voltage and outdoor ambient temperature of the air conditioner are detected, and the corresponding refrigerant pipeline is determined based on the detection results. In addition, matching compressor frequencies are set for different refrigerant pipelines, that is, the second initial compressor frequency is greater than the first initial compressor frequency to ensure normal flow rates of refrigerants in refrigerant pipelines of different lengths.

In step S730, the target temperature increment of the compressor control module is obtained according to the sampling period.

It should be noted that in the current related technology, when the air conditioner operates under high temperature and low voltage conditions, the temperature rise of the compressor control module, such as the Intelligent Power Module (IPM), is relatively high, resulting in a negative impact on the compression. The reliability of machine control operation is reduced.

In step S740, the corresponding target frequency reduction amount is determined according to the target temperature increment and the preset temperature rise frequency relationship. The temperature rise frequency relationship is used to determine the first initial compressor frequency or the second initial compressor frequency when the temperature increases. The target frequency reduction amount.

In some embodiments, the same or different temperature rise frequency relationships may be used for the first refrigerant line (or first initial compressor frequency) and the second refrigerant line (or second initial compressor frequency).

In step S751, the first initial compressor frequency is adjusted according to the target frequency reduction amount corresponding to the first initial compressor frequency to obtain the first corrected compressor frequency, and the first compressor correction signal is sent so that the compressor adjusts to the first corrected frequency. compressor frequency operation.

In step S753, the second initial compressor frequency is adjusted according to the target frequency reduction amount corresponding to the second initial compressor frequency, a second corrected compressor frequency is obtained, and a second compressor correction signal is sent, so that the compressor adjusts to the second corrected frequency. compressor frequency operation.

Through the embodiment of the present application, after the compressor operates at the initial frequency, the frequency of the compressor is updated accordingly according to the temperature rise condition of the IPM, which can effectively ensure the reliability of the frequency control operation of the compressor.

In some examples of embodiments of the present application, the first initial compressor frequency is set with a corresponding first temperature rise frequency relationship, and the second initial compressor frequency is set with a corresponding second temperature rise frequency relationship. On the one hand, when the compressor frequency is determined to be the first initial compressor frequency, the first target frequency reduction amount corresponding to the target temperature increment is determined according to the first temperature rise frequency relationship. On the other hand, when the compressor frequency is determined to be the second initial compressor frequency, a second target frequency reduction amount corresponding to the target temperature increment is determined based on the second temperature rise frequency relationship, and the second target frequency reduction amount is greater than the first target Frequency reduction amount. Therefore, when the same temperature increment is detected, the frequency reduction amount for the second initial compressor frequency is greater than the frequency reduction amount for the first initial compressor frequency, and the frequency reduction amount that matches the computer board temperature can be matched more quickly. Compressor frequency.

Through the embodiments of this application, when the air conditioner is running, the high temperature and low voltage working conditions of the air conditioner are detected, and the corresponding refrigerant pipeline is determined based on the detection results. Each refrigerant pipeline is equipped with an initial compressor frequency corresponding to the current outdoor ambient temperature. , and then detect whether the IPM temperature rise reaches the preset value, and then perform frequency reduction processing based on the preset relationship. Therefore, when an abnormality in the power supply voltage of the air conditioner is detected, the refrigerant shunt mode is updated, and corresponding frequency reduction processing is performed based on temperature changes, which can effectively optimize the air conditioning effect and improve the user experience of the air conditioner.
