Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and specifically provides an operation monitoring method and medium for an air conditioning. Background Art

[0002] With the development of technology, some new types of refrigerants are used in air conditioners, especially in commercial multi-split air conditioning systems. These new types of refrigerants are usually explosive and toxic substances. Therefore, it is necessary to focus on preventing refrigerant leakage. The sudden power failure of the air conditioner power supply is a scenario that easily leads to refrigerant leakage. Specifically, if the valve in the refrigerant pipeline (such as an electronic expansion valve) is in an open state when the power supply fails, the valve will remain in the position before the power failure after the power supply fails, resulting in the risk of refrigerant leakage.

[0003] In the prior art, a backup power supply is usually configured for the air conditioner, and the backup power supply can supply power to the air conditioner in the event of a power failure, thereby controlling the above-mentioned valve to close and switching the refrigerant pipeline to a non-circulating state. However, the backup power supply may not be able to support the refrigerant pipeline to switch to a non-circulating state in some situations (such as insufficient power, failure, etc.). Therefore, even if a backup power supply is configured, there may still be a risk of refrigerant leakage.

[0004] Accordingly, the art needs to provide a new technical solution to solve the above problems. Summary of the invention

[0005] In order to at least partially overcome the above-mentioned defects, the present invention is proposed. Specifically, the present invention provides an air conditioner operation monitoring method and medium that can at least partially solve the technical problem that there is still a risk of refrigerant leakage when a backup power supply is configured.

[0006] A first aspect of the present invention provides an operation monitoring method for an air conditioner, wherein the air conditioner comprises a power supply and a backup power supply, wherein when the power supply is in a power-off state, the backup power supply can release electric energy so that: the refrigerant pipeline of the air conditioner can be switched to a non-circulating state with the aid of the electric energy, and the method comprises: obtaining operating parameters of the backup power supply and the state of the power supply; if the power supply is in a powered-on state, determining the state of the backup power supply according to the operating parameters.

[0007] It can be seen that in this embodiment, when the power supply is energized (that is, when the power supply is charging the backup power supply), the state of the backup power supply is determined according to the operating parameters. Thus, the user can more accurately grasp the state of the backup power supply, such as whether the backup power supply is fully charged, whether the backup power supply has failed, etc., and therefore can promptly handle abnormal conditions in the backup power supply, thereby avoiding the situation where the power supply is cut off and the backup power supply cannot supply power normally, resulting in the refrigerant pipeline being unable to switch to a non-circulating state, thereby reducing the risk of refrigerant leakage in the air conditioner.

[0008] In a technical solution of the above method, the operating parameter includes the voltage of the backup power supply.

[0009] With such a configuration, a possible way of monitoring the status of the backup power supply is provided.

[0010] In a technical solution of the above method, when the power supply is in a powered state, the power supply can charge the backup power supply, and the operating parameters include a charging time for the power supply to charge the backup power supply.

[0011] This configuration provides another possible way to monitor the state of the backup power supply. Combining the charging time with the voltage of the backup power supply to jointly determine the state of the backup power supply can seek to more accurately determine the state of the backup power supply.

[0012] In a technical solution of the above method, the state of the backup power supply includes a first state. In the step of "determining the state of the backup power supply according to the operating parameters", if the charging time is greater than the set time and the voltage of the backup power supply is less than or equal to a first set value, the state of the backup power supply is determined to be the first state.

[0013] Through such a configuration, a method for determining the state of the backup power supply according to the voltage of the backup power supply and the charging time is provided. The first state here may include a fault state such as a leakage state, and determining the first state of the backup power supply helps to prompt the user when the backup power supply fails, thereby reducing the risk of refrigerant leakage.

[0014] In a technical solution of the above method, the state of the backup power supply includes a second state. In the step of "determining the state of the backup power supply according to the operating parameters", if the charging time is greater than the set time and the voltage of the backup power supply is greater than the first set value and less than or equal to the second set value, the state of the backup power supply is determined to be the second state.

[0015] Through such a configuration, another method of determining the state of the backup power supply according to the voltage of the backup power supply and the charging time is provided. The second state here may include a state related to the service life of the backup power supply, such as expiration of life. Determining the second state of the backup power supply helps to promptly remind the user when the service life of the backup power supply expires, thereby reducing the risk of refrigerant leakage.

[0016] In a technical solution of the above method, the state of the backup power supply includes a third state. In the step of "determining the state of the backup power supply according to the operating parameters", if the charging time is greater than the set time and the voltage of the backup power supply is greater than a second set value, the state of the backup power supply is determined to be the third state.

[0017] This configuration provides another method for determining the state of the backup power supply based on the voltage of the backup power supply and the charging time. The third state may include a state in which the backup power supply is fully charged, or a state in which the power of the backup power supply is sufficient to support the refrigerant pipeline to switch to a non-circulating state.

[0018] In a technical solution of the above method, the method includes: according to the state of the backup power supply, outputting prompt information corresponding to the state.

[0019] This configuration enables the user to better monitor the status of the backup power supply.

[0020] In a technical solution of the above method, the method includes: if the power supply is powered off and is in a power-off state, determining whether the backup power supply can support the refrigerant pipeline to switch to a non-circulation state based on the operating parameters; if the backup power supply cannot support the refrigerant pipeline to switch to a non-circulation state, outputting a prompt message that the refrigerant pipeline cannot be switched to a non-circulation state.

[0021] It can be seen that in this embodiment, when the power supply is cut off, it is determined whether the backup power supply can switch the refrigerant pipeline to the non-circulating state, and when the power of the backup power supply cannot switch the refrigerant pipeline to the non-circulating state, a prompt message is output so that the user can handle it in time.

[0022] In a technical solution of the above method, the method includes: in the step of "determining whether the backup power supply can support the refrigerant pipeline to switch to a non-circulation state based on the operating parameters", if the backup power supply can switch the refrigerant pipeline to a non-circulation state, then at least determining the circulation state of the refrigerant pipeline based on the operating parameters.

[0023] Through such a structure, the user can timely understand the flow status of the refrigerant pipeline, so that when an unexpected situation occurs when the refrigerant pipeline is switched to a non-circulating state (such as a stuck valve, etc.), timely processing can be carried out to avoid refrigerant leakage.

[0024] A second aspect of an embodiment of the present invention provides a computer-readable storage medium, which is suitable for storing a plurality of program codes, and the program codes are suitable for being loaded and run by a processor to execute the air conditioner operation monitoring method as described in any one of the above items.

[0025] A third aspect of an embodiment of the present invention provides a computer device, comprising a memory and a processor, wherein the memory is suitable for storing a plurality of program codes, and when the program codes are executed by the processor, the air conditioning operation monitoring method as described in any one of the above items can be implemented.

[0026] It can be understood that the computer-readable storage medium and the computer device have all the technical effects of the air conditioning operation monitoring method described in any of the above items, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The disclosure of the present invention will become more easily understood with reference to the accompanying drawings. It is easy for those skilled in the art to understand that these drawings are only for illustrative purposes and are not intended to limit the scope of protection of the present invention. In addition, similar numbers in the figures are used to represent similar components, among which:

[0028] Figure 1 is a schematic diagram of the circuit structure of an air conditioner targeted by a method according to an embodiment of the present invention;

[0029] Figure 2 is a flow chart of a method according to an embodiment of the present invention. DETAILED DESCRIPTION

[0030] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0031] The embodiment of the present invention first provides an operation monitoring method of an air conditioner. The air conditioner may include a power supply and a backup power supply. When the power supply fails, the backup power supply can release electric energy so that the refrigerant pipeline of the air conditioner can be switched to a non-circulating state with the help of the electric energy.

[0032] Figure 1The circuit structure diagram of an air conditioner targeted by the air conditioner operation monitoring method of an embodiment is shown. The air conditioner can be a household air conditioner, such as a household wall-mounted air conditioner, a household cabinet air conditioner, a household duct air conditioner, etc., or a commercial multi-split air conditioning system, etc., or other air conditioning systems, etc.

[0033] In the illustrated embodiment, the power supply 1 and the backup power supply 2 are connected to the main controller 3 and the valve driver 4 of the air conditioner to supply power to them. The main controller 3 may include one or more processors, and the valve driver 4 may be a driving device such as a PWM driver that can drive the valve to move, which can drive the valve M to move, thereby changing the flow state of the refrigerant pipeline of the air conditioner. The valve M here may include but is not limited to the electronic expansion valve in the refrigerant pipeline of the air conditioner, etc., which can change the flow state of the refrigerant pipeline, and there is no limitation on this. In the case where the air conditioner is a multi-split air conditioning system, the power supply 1 may be the total power supply of the air conditioning system, or the power supply of one or a group of air conditioners in the air conditioning system. Similarly, the backup power supply 2 may be a backup power supply 2 shared by the air conditioning system, or a backup power supply 2 dedicated to one or a group of air conditioners in the air conditioning system.

[0034] The main controller 3 can output a control signal to the valve driver 4, so that the valve driver 4 controls the valve M in the refrigerant circuit of the air conditioner to operate. Similarly, in the case where the air conditioner is a multi-split air conditioner system, the main controller 3 can refer to a controller that can control all air conditioners in the air conditioner system, or can refer to a controller that can control one or a group of air conditioners in the air conditioner system, and the same is true for the valve driver 4.

[0035] The power supply 1 can be connected to the power grid and output 12V DC with the help of the transformer 5, so as to power the main controller 3, the valve driver 4, etc. Obviously, the output of the transformer 5 is not limited to 12V DC, and those skilled in the art can reasonably set the output of the transformer 5 according to the actual power demand. The power failure of the power supply 1 means that the power supply 1 cannot work normally due to power failure, power loss, or the quality of electricity does not meet the requirements. The opposite is true when the power supply 1 is powered on.

[0036] The backup power supply 2 may include one or more charging capacitors. The advantage of using capacitors as the backup power supply 2 is that the charging speed of the capacitors is extremely fast, which can ensure that the backup power supply 2 is quickly charged when the power supply 1 is powered, thereby avoiding as much as possible that the backup power supply 2 is in an undercharged state when the power supply 1 is powered off. In this case, the rated voltage of the backup power supply 2 should be greater than or equal to the voltage required to power the main controller 3 and the valve driver 4. For example, assuming that the main controller 3 and the valve driver 4 require 12V DC, the rated voltage of the backup power supply 2 should be greater than or equal to 12V, such as 15V, 16V, etc. Obviously, those skilled in the art can also choose to use other structural forms of the backup power supply 2 according to actual use requirements, such as selecting a rechargeable battery (such as a lithium battery, etc.) as the backup power supply 2.

[0037] In a possible implementation, when the power supply 1 is powered, the power supply 1 can charge the backup power supply 2 .

[0038] As an example, the power supply 1 may be connected to the relay coil 6, and a normally closed contact 7 may be provided on the path connecting the backup power supply 2 with the main controller 3 and the valve driver 4. The normally closed contact 7 is connected to the relay coil 6. When the power supply 1 loses power, the relay coil 6 is powered off and the normally closed contact 7 is closed, so that the backup power supply 2 supplies power to the main controller 3 and the valve driver 4. When the power supply 2 is powered on, the relay coil 6 is powered on and the normally closed contact 7 is opened, so that the power supply 1 charges the backup power supply 2.

[0039] In the case of adopting this connection mode, the power supply 1 can automatically charge the backup power supply 2 when it is powered on, and at the same time, the backup power supply 2 can automatically release the electric energy when the power supply 1 is powered off. Obviously, the connection mode of the power supply 1 and the backup power supply 2 is not limited to this. For example, the backup power supply 2 can also be connected to the power supply 1 through a diode structure to achieve the above functions. Those skilled in the art can make a choice according to actual use requirements.

[0040] Furthermore, the normally closed contacts 7 may include at least two, wherein at least one normally closed contact 7 is used to connect the backup power supply 2 to the circuit where the main controller 3, the valve driver 4 and other components are located, and at least one normally closed contact 7 is connected in parallel with the charging resistor 8, and the charging resistor 8 is connected in series with the backup power supply 2. When the backup power supply 2 is used for power supply, the normally closed contact 7 is closed, so that the charging resistor 8 is short-circuited, thereby avoiding the loss of the power of the backup power supply 2. When the backup power supply 2 is charged, the normally closed contact 7 is disconnected, so that the charging resistor 8 is connected to the circuit, to prevent the capacitor of the backup power supply 2 from being broken down due to inrush current during the charging process.

[0041] Furthermore, a voltage detection circuit 9 may be provided at both ends of the backup power supply 2 , and the voltage detection circuit 9 may be used to monitor the voltage of the backup power supply 2 . A device for measuring voltage, such as a voltmeter, may be provided in the voltage detection circuit 9 .

[0042] Furthermore, the circuit structure may also include a prompting device 10, which may be a device with a prompting function such as a display screen, an alarm, an indicator light, etc. In the case where the air conditioner is a commercial multi-split air-conditioning system, the prompting device 10 may be set at the host computer of the air-conditioning system.

[0043] The following will mainly focus on Figure 1 The circuit structure shown in FIG. 1 is used as an example to describe the operation monitoring method of the air conditioner of the embodiment of the present invention. However, those skilled in the art can understand that the method provided by the embodiment of the present invention can be applied to any air conditioner equipped with a backup power supply.

[0044] Figure 2 A flowchart showing a method according to an embodiment of the present invention is shown. Figure 2 , the method of the embodiment of the present invention includes:

[0045] Step S201: Acquire the operating parameters of the backup power supply and the status of the power supply.

[0046] Step S202: If the power supply is in a powered state, the state of the backup power supply is determined according to the operating parameters.

[0047] It can be seen that in this embodiment, the status of the backup power supply is determined when the power supply is energized (that is, when the power supply is charging the backup power supply), so that the user can more accurately grasp the status of the backup power supply, such as whether the backup power supply is fully charged, whether the backup power supply has failed, etc., and therefore can promptly handle abnormal conditions in the backup power supply (repair or replace the backup power supply 2, etc.), thereby avoiding the situation where the power supply is powered off and the backup power supply cannot supply power normally, thereby further reducing the risk of refrigerant leakage.

[0048] Specifically, in this embodiment, the state of the power supply 1 can be determined according to the state of the normally closed contact 7 described above, or the state of the power supply 1 can be determined according to the voltage across the power supply 1, etc., without limitation.

[0049] The operating parameters of the backup power supply 2 may include, for example, the voltage and current of the backup power supply 2 and other parameters related to the operating state of the backup power supply 2. These operating parameters can be obtained by setting a detection structure (such as the voltage detection loop 9 mentioned above) in the circuit structure of the air conditioner. When the power supply is powered, the state of the backup power supply 2 can be determined according to the above operating parameters. The "state" here may include the power of the backup power supply 2, the health of the backup power supply 2 (such as capacity, life, etc.), the fault condition of the backup power supply 2, etc. Those skilled in the art can determine the specific operating parameters that need to be obtained in the actual application process according to the actual structure and operation mode of the backup power supply 2, as well as the specific method of determining the state of the backup power supply 2 according to these operating parameters.

[0050] In an optional embodiment, obtaining the operating parameters of the backup power supply in step S201 may include obtaining the operating parameters of the backup power supply 2 in real time, and in step S202, if the power supply 1 is in a powered state, the state of the backup power supply 2 can be determined in real time based on the operating parameters obtained in real time, so as to monitor the state of the backup power supply 2 in real time.

[0051] Obviously, those skilled in the art may also choose to perform the above steps once at a certain interval. In this case, the time interval may be fixed or not. For example, when the power supply 2 has not yet been fully charged, the above steps may be performed at relatively short time intervals. When the power supply 2 is fully charged, the above steps may be performed at relatively long time intervals.

[0052] In a possible implementation, the operating parameter may include the voltage of the backup power supply. Through such a configuration, an optional operating parameter is provided. As described above, the backup power supply 2 may include one or more capacitors, and the voltage of the capacitor is positively correlated with the amount of electricity stored therein, so the voltage of the backup power supply 2 can better reflect the state of the backup power supply 2. For example, if the voltage of the backup power supply 2 is increasing, it can be determined that the state of the backup power supply 2 is charging. If the voltage of the backup power supply 2 is stabilized near the rated voltage, or the voltage of the backup power supply 2 reaches a value greater than the power supply voltage, it can be determined that the state of the backup power supply 2 is charging completed. If the voltage of the backup power supply 2 shows a downward trend (when the power supply 1 is powered), it can be determined that the state of the backup power supply 2 is a fault state. Obviously, those skilled in the art can understand that in the case where the backup power supply 2 adopts other structures, the state of the backup power supply 2 can also be determined according to the voltage of the backup power supply 2.

[0053] In a possible implementation, as described above, when the power supply 1 is powered, the power supply 1 can charge the backup power supply 2. In this case, the operating parameters may also include the charging time for the power supply 1 to charge the backup power supply 2.

[0054] In this embodiment, the charging time is combined with the voltage of the backup power source 2 to jointly determine the state of the backup power source 2, so that the state of the backup power source 2 can be determined more accurately.

[0055] In adopting Figure 1 In the case of the circuit structure shown in , the power supply 1 automatically starts to charge the backup power supply 2 after being powered on, so the power supply 1 power-on time can be used as the charging time of the backup power supply 2. In the case of other circuit structures, the time when the backup power supply 2 starts charging can be recorded and the charging time can be determined according to the time.

[0056] In other possible implementations, the backup power supply 2 may be configured to be charged with the aid of other power sources instead of the power supply 1 . In this case, the operating parameters may still include the charging time of the backup power supply 2 .

[0057] In a possible implementation, the state of the backup power supply may include a first state. In the step of "determining the state of the backup power supply according to operating parameters", if the charging time is greater than the set time and the voltage of the backup power supply is less than or equal to the first set value, the state of the backup power supply can be determined to be the first state.

[0058] Through such a configuration, an optional method of determining the state of the backup power supply according to the voltage of the backup power supply and the charging time is provided. The first state of the backup power supply 2 may include a leakage state or other common fault states. In this embodiment, the fault state of the backup power supply 2 is monitored, so as to help the user to handle the situation in a timely manner when the backup power supply 2 fails, such as shutting down the air conditioner and replacing the backup power supply 2, etc., to avoid refrigerant leakage. It should be noted that at any time point after the charging time is greater than the set time, as long as the voltage of the backup power supply 2 is less than or equal to the first set value, the state of the backup power supply 2 can be determined to be the first state.

[0059] In a possible implementation, the state of the backup power supply 2 may include a second state. In the step of "determining the state of the backup power supply according to the operating parameters", if the charging time is greater than the set time, and the voltage of the backup power supply is greater than the first set value and less than or equal to the second set value, then the state of the backup power supply can be determined to be the second state.

[0060] Through such a configuration, another method of determining the state of the backup power supply according to the voltage of the backup power supply and the charging time is provided. In this embodiment, the second state may include the state of battery life expiration. In this embodiment, the life expiration state of the backup power supply 2 is monitored, so as to help the user to deal with it in time when the life of the backup power supply 2 expires to avoid refrigerant leakage. Similarly, at any time point after the charging time is greater than the set time, as long as the voltage of the backup power supply 2 is greater than the first set value and less than the second set value, the state of the backup power supply 2 can be determined to be the life expiration state.

[0061] In a possible implementation, the state of the backup power supply 2 may include a third state. In the step of "determining the state of the backup power supply according to the operating parameters", if the charging time is greater than the set time and the voltage of the backup power supply is greater than the second set value, it can be determined that the state of the backup power supply is the second state.

[0062] This configuration provides another method for determining the state of the backup power supply based on the voltage of the backup power supply and the charging time. In this embodiment, the third state may include a fully charged state, or a state where the power reaches a level sufficient to support the refrigerant pipeline switching to a different state.

[0063] The set duration mentioned in the several embodiments described above may be related to the time required for the backup power supply 2 to be fully charged under normal conditions, such as being set to 5 minutes. The first set value and the second set value may be related to the voltage of the backup power supply 2 in a fully charged state (such as 90%, 85%, 80%, 70%, etc. of the rated voltage), and those skilled in the art may freely set the first set value and the second set value according to actual use requirements, or may determine the first set value and the second set value by performing a charge and discharge test on the backup power supply 2, without limitation. As an example, assuming that the voltage of the backup power supply 2 in the fully charged state should be greater than 12V, the first set value may be 10V, and the second set value may be 11V.

[0064] It is understandable that the state of the backup power supply 2 is not limited thereto, such as the state of the backup power supply 2 may also include a fourth state. The fourth state may include a charging state, and the fourth state may be further divided into a charging start state, a charging in progress state, etc. according to the progress of charging. Still taking the backup power supply 2 described above as an example, when the charging time is less than the set time, when the voltage value is between 5-7V, its state may be determined as charging start, and when the voltage value is between 7-12V, its state may be determined as charging in progress. Alternatively, the charging progress may be determined according to the ratio between the voltage value of the backup power supply 2 and the rated voltage to divide the fourth state more finely, so that the user can more accurately control the charging status of the backup power supply 2.

[0065] In one possible implementation, after determining the status of the backup power supply 2, prompt information corresponding to the status can be output according to the status of the backup power supply. For example, if it is determined that the backup power supply 2 is charging, a prompt information that it is charging is output; if it is determined that the charging of the backup power supply 2 is complete, a prompt information that the charging is complete is output; if it is determined that the backup power supply 2 is leaking, a prompt information that the backup power supply 2 is leaking is output, etc. The prompt information can be perceived by the user, so that the user can understand the status of the backup power supply 2, and then execute corresponding measures (for example, actively shutting down the air conditioner and repairing the backup power supply 2 when the backup power supply 2 fails) to avoid the situation where the backup power supply 2 cannot support the valve closing when the power supply 1 loses power.

[0066] The prompt information can be output to a prompt device configured for the air conditioner, or a prompt device connected to the air conditioner, etc. The prompt device can be a display screen, a prompt light, a sound, an alarm, etc. that can prompt the user with the help of light signals and / or sound signals. Alternatively, the prompt information can be output to a user terminal, an upper computer of the air conditioner, etc. that can interact with the user. Furthermore, the prompt device can emit different light signals / sound signals to display prompt information corresponding to different states, such as displaying different texts on the display screen to display prompt information corresponding to different states. Those skilled in the art can make a choice based on actual use requirements, and there is no limitation to this.

[0067] In a possible implementation, the method also includes the following steps: in the event of a power failure, determining whether the backup power supply can support the refrigerant pipeline to switch to a non-circulating state based on operating parameters; if the backup power supply cannot support the refrigerant pipeline to switch to a non-circulating state, outputting a prompt message that the refrigerant pipeline cannot switch to a non-circulating state.

[0068] It is understandable that in some special usage scenarios, even if the user has determined that the backup power supply 2 is in a normal state by means of the above method, when the power supply 1 loses power, the backup power supply 2 may still not be able to support the refrigerant pipeline to switch to a non-circulating state. For example, when the power supply 1 loses power, the backup power supply 2 may just start charging (because this state is a normal state, the user will not process it after determining this state), resulting in insufficient power to support the refrigerant pipeline to switch to a non-circulating state. For this reason, in this embodiment, when the power supply 1 loses power, it is determined according to the operating parameters whether the backup power supply 2 can support the refrigerant pipeline to switch to a non-circulating state, and when the judgment result is that the backup power supply 2 cannot support the refrigerant pipeline to switch to a non-circulating state, the corresponding prompt information is output so that the user can handle it in time, such as manually controlling the valve in the refrigerant pipeline, connecting other power sources to control the valve in the refrigerant pipeline, etc., so as to avoid refrigerant leakage.

[0069] The operating parameters used to determine whether the backup power supply 2 can support the refrigerant pipeline switching to the non-circulating state and the operating parameters used to determine the state of the backup power supply 2 can be the same, or different or not completely the same (in this case, when the operating parameters are obtained in step S201, all possible operating parameters that may be applied should be obtained together). Those skilled in the art can make a choice according to actual needs, and there is no limitation on this.

[0070] As an example, when the operating parameters include the voltage of the backup power supply 2 and the charging time for the power supply 1 to charge the backup power supply 2, when judging whether the backup power supply 2 can support the refrigerant pipeline to switch to the non-circulation state according to the operating parameters, if the voltage is less than a set threshold (the threshold can be determined based on the amount of electricity required to switch the refrigerant pipeline to the non-circulation state) and / or the charging time is less than a set time (the set time can be determined based on the time required for the backup power supply 2 to be fully charged or charged to a set amount of electricity, and the set amount of electricity can be determined based on the amount of electricity required to switch the refrigerant pipeline to the non-circulation state), it can be judged that the backup power supply 2 cannot support the refrigerant pipeline to switch to the non-circulation state.

[0071] It should be noted that judging whether the backup power supply can support the refrigerant pipeline to switch to a non-circulating state obviously only needs to be executed when the refrigerant pipeline is in a circulating state. Therefore, before executing the step of "judging whether the backup power supply can support the refrigerant pipeline to switch to a non-circulating state according to the operating parameters", it is necessary to first determine whether the refrigerant pipeline is in a circulating state. As an example, it can be determined based on the voltage change trend of the backup power supply 2 after the power supply 1 is powered off. If the change trend includes a downward trend, it can be determined whether the refrigerant pipeline is in a circulating state. Of course, it is also possible to choose to determine whether the refrigerant pipeline is in a circulating state based on the operating status of the air conditioner before the power supply 1 is powered off or the valve opening in the refrigerant pipeline.

[0072] Furthermore, in some of the embodiments described above, prompt information corresponding to the status of the backup power supply 2 will be output, and in the present embodiment, prompt information that the refrigerant pipeline cannot be switched to a non-circulation state will be output. The two can be in the same form (such as both can be presented in the form of text on the display screen of a host computer, a user terminal, and other devices, or both can be in the form of sound broadcasts, or flashing indicator lights, etc.), or they can be in different forms, such as the prompt information that the refrigerant pipeline cannot be switched to a non-circulation state can be output in a relatively more eye-catching manner, etc. Personnel in this field can choose according to actual needs.

[0073] Furthermore, in the step of "determining whether the backup power supply can support the refrigerant pipeline to switch to a non-circulating state according to the operating parameters", if the backup power supply can support the refrigerant pipeline to switch to a non-circulating state, the circulation state of the refrigerant pipeline can be determined at least according to the operating parameters. Through such a structure, the user can timely grasp the circulation state of the refrigerant pipeline after the power supply 1 is powered off, so that when the refrigerant pipeline cannot be switched to a non-circulating state due to other reasons other than the backup power supply 2 (such as valve stuck, etc.), the user can timely discover and handle it.

[0074] Similarly, the operating parameters used here and the operating parameters used in other steps above can be the same, different or not completely the same. When determining the flow state of the refrigerant pipeline, the above operating parameters can be used alone or in combination with other parameters.

[0075] As an example, the operating parameters may include the power-off duration, and the voltage of the backup power supply 2. It can be determined based on the operating parameters and the control steps of the valve controller 4 that when the power-off duration is less than 5S, it can be determined that the circulation state of the refrigerant pipeline begins to switch. When the power-off duration is less than the set duration (the set duration can be determined based on the time required for the refrigerant pipeline to switch from the maximum opening to the non-circulating state, such as 100S), and the voltage of the backup power supply 2 is between 8V-12V (this range can be specifically determined based on the amount of electricity consumed by the valve closing), it can be determined that the refrigerant pipeline is switching to the non-circulating state. When the power-off duration is greater than the set duration, the voltage of the backup power supply 2 is between 5V-8V, and the control steps of the valve driver 4 reach the set number of steps, it can be determined that the refrigerant pipeline has switched to the non-circulating state.

[0076] Obviously, those skilled in the art may also adopt other suitable methods to determine the flow state of the refrigerant pipeline. For example, an opening monitoring device may be provided at the valve, and the state of the valve may be monitored according to the opening monitoring device to determine the flow state of the refrigerant pipeline. There is no limitation to this.

[0077] Furthermore, in this embodiment, prompt information corresponding to the flow status can also be output according to the flow status of the refrigerant pipeline. The specific output method of the prompt information can refer to the output method of other types of prompt information mentioned above, which will not be repeated here.
