As shown in fig. 2, the air conditioner includes a radiator 210, a first refrigerant pipeline 221, a second refrigerant pipeline 223, a compressor 230 and a valve 240, wherein the valve 240 controls the refrigerant fluid to switch between the first refrigerant pipeline 221 and the second refrigerant pipeline 223 to use the refrigerant pipeline, and the refrigerant fluid enters the radiator 210 from the compressor 230 through the first refrigerant pipeline 221 or the second refrigerant pipeline 223 to exchange heat.
Fig. 3 is a flowchart showing an example of an air conditioner operation control method according to an embodiment of the present application. The implementation subject of the method of the embodiment of the application can be various processors or controllers with processing capability or computing capability, and can be arranged in an air conditioner terminal, such as an outdoor unit, through data local processing, and can also be combined with data communication between a server, so as to realize the control of the smooth running of the air conditioner when the power supply voltage of the air conditioner floats, optimize the air conditioner effect and save the consumption of electric power resources.
As shown in fig. 3, in step S310, a power supply voltage of an air conditioner is acquired.
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 may be set according to a locally specified supply voltage of the utility grid, for example 220V for chinese utility and 110V for japan. In some embodiments, when the air conditioner receives a start-up instruction, the air conditioner can detect the power supply voltage to identify whether the power supply voltage is too low or not, and timely detect the low-voltage operation 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 communicated 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 communicated from the compressor to the radiator through the second refrigerant pipeline or the first refrigerant pipeline, wherein the first refrigerant contact area between the first refrigerant pipeline and the radiator is smaller than the second refrigerant contact area between the second refrigerant pipeline and the radiator.
In connection with the example of fig. 2, switching from the first refrigerant line 221 to the second refrigerant line 223 is accomplished by generating a valve control signal to the valve 240.
According to the embodiment of the application, when the reduction of the power supply voltage of the air conditioner is detected, the refrigerant pipeline with larger refrigerant contact area is switched to be used, so that the air conditioner effect is optimized to a certain extent, and the workload of the compressor system can be effectively reduced under the same external temperature environment or indoor and outdoor temperature difference condition, and the electric quantity consumed by the air conditioner is saved.
Fig. 4 shows a block diagram of a first refrigerant line and a second refrigerant line for switching according to an embodiment of the present application.
As shown in fig. 4, the refrigerant circuit of the air conditioner includes a main refrigerant pipe 410 for connecting the radiator and the compressor, bypass branches 420 and 430 connected in parallel to the main refrigerant pipe 410, the main refrigerant pipe 410 and the bypass branches 420 and 430 are respectively used for connecting the radiator and the compressor, a reversing valve 440 (for example, a dredging valve may be used) is used for controlling the refrigerant fluid in the pipe to flow in a first fluid direction or a second fluid direction, and corresponding one-way conducting valves 421 and 431 are respectively arranged on the bypass branches 420 and 430 to conduct the first fluid direction (as the arrow direction in fig. 4) and cut off the second fluid direction (for example, the direction opposite to the arrow direction in fig. 4).
Specifically, when it is detected that the mains voltage is normal and a first refrigerant pipe with a smaller contact area is required to be used, the flow of the refrigerant fluid in the second fluid direction is controlled based on the reversing valve 440, so that the refrigerant fluid can only be communicated from the compressor of the air conditioner to the radiator through the main refrigerant pipe 410, but cannot pass through the bypass branches 420 and 430 in the corresponding cut-off state. In addition, when it is detected that the mains voltage is reduced and a second refrigerant pipeline with a larger corresponding refrigerant contact area is required to be used, the flow of the refrigerant fluid in the first fluid direction is controlled based on the reversing valve 440, so that the refrigerant fluid is communicated to the radiator from the compressor of the air conditioner through the main refrigerant pipeline and each bypass branch, and the refrigerant contact area between the refrigerant fluid and the heat exchanger in the low-pressure frequency-limiting working state is increased.
Fig. 5 is a schematic exterior view illustrating a refrigerant circuit of an outdoor unit of an air conditioner according to an embodiment of the application.
As shown in fig. 5, the refrigerant circuit of the outdoor unit of the air conditioner comprises a main refrigerant pipe 510, a dredging valve (not shown) for controlling the flow direction of the refrigerant, and at least one bypass branch 520, wherein the bypass branch 520 is provided with a one-way conduction valve for conducting the refrigerant in a specific fluid direction (such as the arrow direction in fig. 5).
In some embodiments, when the power supply voltage value of the air conditioner is detected to be normal, the refrigerant flows out from the interface 511 through the regulation and control of the dredging valve, and exchanges heat with the radiator through the main refrigerant pipeline 510. In addition, when the abnormal supply voltage value of the air conditioner is detected, the refrigerant flows out from the interface 513 through the regulation and control of the dredging valve, and exchanges heat with the radiator through the main refrigerant pipeline 510 and the bypass branch 520.
Fig. 6 illustrates a flowchart of an example of an air conditioner operation control method according to an embodiment of the present application.
As shown in fig. 6, in step S610, if it is determined that the supply voltage is lower than the voltage threshold, the outdoor environment temperature is compared with a preset temperature threshold, and the outdoor environment temperature is the temperature of the environment in which 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 line control signal is sent so that the refrigerant fluid is communicated from the compressor to the radiator through the second refrigerant line.
In step S623, if it is determined that the outdoor ambient temperature is less than or equal to the temperature threshold, a first line control signal is sent such that the refrigerant fluid is communicated from the compressor to the radiator via the first refrigerant line.
It should be noted that, when the outdoor environment temperature is too high, for example, exceeds 48 ℃, the compressor is more likely to enter the frequency-limiting working state under the low-pressure and high-temperature working condition, so that the refrigeration effect of the air conditioner is poor, the workload of the compressor system is increased, and the poor air conditioning effect and the high air conditioning electricity charge are caused. According to the embodiment of the application, when the lower power supply voltage of the air conditioner is detected, whether the ambient temperature is too high is identified, and under the condition that the ambient temperature is too high, the control is switched to the refrigerant pipeline with the higher refrigerant contact area for refrigerating, so that the air conditioner effect is optimized, and the workload of a compressor system is reduced.
Fig. 7 is a flowchart showing an example of an air conditioner 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 S721, when the power supply voltage is not lower than the voltage threshold, a first compressor control signal is transmitted so that the compressor operates at a first initial compressor frequency, such that refrigerant fluid is communicated from the compressor to a radiator of the air conditioner through a first refrigerant line.
In step S723, when the supply voltage is below the voltage threshold, a second compressor control signal is sent such that the compressor operates at a second initial compressor frequency such that refrigerant fluid is communicated from the compressor to a radiator of the air conditioner via a second refrigerant line, the second initial compressor frequency being greater than the first initial compressor frequency.
In some embodiments, before the air conditioner is started, the power supply voltage and the outdoor environment temperature of the air conditioner are detected, and the adoption of the corresponding refrigerant pipeline is judged according to the detection result. In addition, the matched compressor frequency is respectively arranged for different refrigerant pipelines, namely the second initial compressor frequency is larger than the first initial compressor frequency, so that the normal flow velocity of the refrigerant in the refrigerant pipelines with different lengths is ensured.
In step S730, a target temperature increase of the compressor control module is obtained according to the sampling period.
It should be noted that, in the related art, when the air conditioner is operated under the high-temperature low-voltage condition, the temperature rise of the compressor control module, such as the intelligent power module (Intelligent Power Module, IPM), is relatively high, resulting in a decrease in reliability of the compressor control operation.
In step S740, a corresponding target frequency reduction is determined according to the target temperature increase and a preset temperature rise frequency relationship, where the temperature rise frequency relationship is used to determine the target frequency reduction of the first or second initial compressor frequency at the temperature increase.
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 a first corrected compressor frequency, and a first compressor correction signal is transmitted so that the compressor operates at the first corrected compressor frequency.
In step S753, the second initial compressor frequency is adjusted according to the target frequency reduction amount corresponding to the second initial compressor frequency to obtain a second corrected compressor frequency, and the second compressor correction signal is transmitted so that the compressor operates at the second corrected compressor frequency.
According to the embodiment of the application, after the compressor operates according to the initial frequency, the frequency of the compressor is correspondingly updated according to the temperature rise condition of the IPM, so that the reliability of the frequency regulation operation of the compressor can be effectively ensured.
In some examples of embodiments of the application, the first initial compressor frequency is provided with a corresponding first temperature rise frequency relationship and the second initial compressor frequency is provided with a corresponding second temperature rise frequency relationship. In one aspect, when the compressor frequency is determined to be the first initial compressor frequency, a first target frequency reduction amount corresponding to the target temperature increase is determined according to the first temperature increase 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 increase amount is determined according to the second temperature increase frequency relationship, the second target frequency reduction amount being larger than the first target frequency reduction amount. Thus, when the same temperature increment is detected, the frequency reduction amount for the second initial compressor frequency is larger than that for the first initial compressor frequency, and the compressor frequency matched with the computer board temperature can be matched more quickly.
According to the embodiment of the application, when the air conditioner is in operation, the high-temperature low-voltage working condition of the air conditioner is detected, the corresponding refrigerant pipelines are determined according to the detection result, each refrigerant pipeline is provided with the initial compressor frequency aiming at the current outdoor environment temperature, and then whether the temperature rise of the IPM reaches a preset value or not is detected, and then the frequency is reduced according to the preset relation. Therefore, when the abnormal power supply voltage of the air conditioner is detected, the refrigerant diversion mode is updated, corresponding frequency reduction processing is carried out based on temperature change, the air conditioner effect can be effectively optimized, and the user experience of the air conditioner is improved.
The air conditioner operation control device provided by the application is described below, and the air conditioner operation control device described below and the air conditioner operation control method described above can be referred to correspondingly.
