Fig. 2 is a schematic structural view showing an example of an air conditioning refrigerant circuit to which the air conditioning operation control method according to the embodiment of the present application is applied.
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 main body of the method of the embodiment of the application can be various processors or controllers with processing capability or computing capability, can be arranged in an air conditioner terminal, such as an outdoor unit, can be used for locally processing data and can be used for integrating data communication with a server, so that when the closing of the PFC module of the air conditioner is detected, the operation pressure of an air conditioner system is optimized through the regulation and control of a refrigerant pipeline, and the probability of shutdown failure of the air conditioner is reduced.
As shown in fig. 3, in step S310, an operating state of the PFC module of the air conditioner is acquired, and the operating state is an on state or an off state.
In one example of an embodiment of the present application, the air conditioner may monitor the operating state of the PFC module in real time during operation. In another example of the embodiment of the present application, since the PFC module generally maintains the original state after the start-up, it is also possible to detect the operating state of the PFC module only when the air conditioner is started up. Specifically, in response to an air conditioner starting instruction, the working state of the PFC module of the air conditioner is obtained, so that the working state of the PFC module is detected only when the air conditioner is started, whether the PFC module is in a starting state or a closing state is recognized, and consumption of processing resources of an air conditioner system can be reduced to a certain extent.
In step S320, when the operating state is the start-up state, a first pipeline control signal is sent, so that the refrigerant fluid is communicated from the compressor of the air conditioner to the radiator of the air conditioner through the first refrigerant pipeline.
In step S330, when the working state is the closed state, a second pipeline control signal is sent to enable 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 PFC module is detected to be in the closed state, the refrigerant pipeline with larger refrigerant contact area can be switched and used, so that the work load of a compressor system can be effectively reduced, and the probability of occurrence of air conditioner shutdown faults is reduced.
Fig. 4 shows a schematic structural 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 PFC module is in the on state, the flow of the refrigerant fluid in the second fluid direction is controlled based on the reversing valve 440 when the first refrigerant pipe having a smaller contact area is required, 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 corresponding to the off state. In addition, when it is detected that the PFC module is in the closed state and a second refrigerant pipe having a larger contact area with the corresponding refrigerant is required, 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 from the compressor of the air conditioner to the radiator through the main refrigerant pipe and each bypass branch, and the contact area between the refrigerant and the heat exchanger is increased when the PFC module is in the closed state.
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 PFC module of the air conditioner is detected to be in a start state, 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 pipe 510. In addition, when the PFC module of the air conditioner is detected to be in a closed state, 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, in the case where it is determined that the PFC module of the air conditioner is in the off state, it is detected whether the air conditioner operation mode is the cooling mode or the heating mode.
In step S620, when it is determined that the air conditioner operation mode is the cooling mode, the outdoor ambient temperature of the air conditioner is compared with a preset temperature threshold.
In step S630, 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 to the radiator through the second refrigerant line.
When the outdoor ambient temperature is too high, for example, exceeds 48 ℃, the difference between the set temperature of the air conditioner and the outdoor ambient temperature is large, and the workload of the air conditioning system is increased. Therefore, when the outdoor environment temperature is overlarge, the pressure of the air conditioning system is overlarge, and the pressure of the air conditioning system is reduced through the control switching of the refrigerant fluid pipeline, so that the air conditioning shutdown fault is avoided when the PFC module is in a closed state.
On the other hand, in step S640, if it is determined that the air conditioner operation mode is the heating mode, a second line control signal is sent, so that the refrigerant fluid is communicated to the radiator through the second refrigerant line. Therefore, when the air conditioner operates in a heating mode, the probability of the occurrence of a radiator frosting working condition due to overlarge temperature difference of the refrigerant of the pipeline is effectively reduced by starting the second refrigerant management with longer pipeline, and the heating effect of the air conditioner can be guaranteed to a certain extent.
In step S650, in case it is determined that the outdoor ambient temperature does not exceed the temperature threshold value, the power supply voltage of the air conditioner is compared with a preset voltage threshold value.
Here, the voltage threshold may be determined from the rated voltage of the utility grid for detecting whether a low voltage condition exists. For example, the rated voltage of the commercial power grid in China is 220V, and the corresponding voltage threshold value can be 170V or other critical point values, so as to realize identification and judgment of the low-voltage operation condition of the air conditioner.
In step S661, when the voltage threshold is greater than the voltage threshold, a first line control signal is sent to enable the refrigerant fluid to be communicated to the radiator through the first refrigerant line.
In step S663, when the voltage threshold does not exceed the voltage threshold, a second line control signal is sent to enable the refrigerant fluid to be communicated to the radiator through the second refrigerant line.
It should be noted that, in some countries and regions, the air conditioner is often in a down-conversion working state under a low voltage due to unstable power supply voltage of the power grid, which also increases the workload of the compressor system to some extent. Therefore, when the outdoor environment temperature is detected to be lower, whether the power supply voltage of the air conditioner is at low voltage is further detected, so that the operation pressure of an air conditioner system is comprehensively identified, and when the system operation pressure is detected to be higher, the multipath flow distribution is started, the system pressure is reduced, and the air conditioner shutdown risk is effectively reduced.
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.
