Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically providing a method and medium for monitoring the operation of an air conditioner. Background Technology

[0002] With technological advancements, new types of refrigerants are being used in air conditioners, especially in commercial multi-split air conditioning systems. These new refrigerants are often explosive or toxic substances, therefore, preventing refrigerant leaks is crucial. A sudden power outage is a common scenario that can lead to refrigerant leaks. Specifically, if valves in the refrigerant piping (such as electronic expansion valves) are open when the power supply fails, they will remain in their pre-power-out position after the power outage, thus posing a risk of refrigerant leakage.

[0003] In existing technologies, air conditioners are typically equipped with a backup power supply. This backup power supply can provide power to the air conditioner in the event of a power outage, thereby controlling the closure of the aforementioned valves and switching the refrigerant lines to a non-flowing state. However, in some situations (such as insufficient power or malfunction), the backup power supply may not be able to support the switching of the refrigerant lines to a non-flowing state. Therefore, even with a backup power supply, there may still be a risk of refrigerant leakage.

[0004] Accordingly, there is a need in this field to provide a new technical solution to address the above-mentioned problems. Summary of the Invention

[0005] To overcome the aforementioned drawbacks to at least some extent, this invention is proposed. Specifically, this invention provides an operation monitoring method and medium for air conditioners that can at least partially solve the technical problem of refrigerant leakage risk even when a backup power supply is configured.

[0006] The first aspect of the present invention provides a method for monitoring the operation of an air conditioner, the air conditioner including 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 electrical energy so that: the refrigerant piping of the air conditioner can be switched to a non-flowing state by means of the electrical energy, the method including: acquiring the operating parameters of the backup power supply and the state of the power supply; if the power supply is in a powered state, determining the state of the backup power supply according to the operating parameters.

[0007] As can be seen, in this embodiment, when the power supply is powered (that is, when the power supply is charging the backup power supply), the status of the backup power supply is determined according to the operating parameters. Thus, the user can more accurately grasp the status of the backup power supply, such as whether the backup power supply is fully charged or whether the backup power supply has malfunctioned. Therefore, the user can deal with the abnormal status of the backup power supply in a timely manner, avoiding the situation where the power supply fails and the backup power supply cannot supply power normally, which would prevent the refrigerant pipeline from switching to a non-flowing state and reduce the risk of air conditioning refrigerant leakage.

[0008] In one technical solution of the above method, the operating parameters include the voltage of the backup power supply.

[0009] This configuration provides a possible way to monitor the status of backup power.

[0010] In one technical solution of the above method, when the power supply is energized, the power supply can charge the backup power supply, and the operating parameters include the charging time of the power supply charging the backup power supply.

[0011] This configuration presents another possible way to monitor the status of backup power. Combining charging time with backup power voltage to determine the backup power's status allows for a more accurate assessment.

[0012] In one 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, then the state of the backup power supply is determined to be the first state.

[0013] This configuration provides a method for determining the status of the backup power supply based on its voltage and charging time. The first status here can include fault conditions such as leakage. Determining the first status of the backup power supply helps to alert the user when a failure occurs, thereby reducing the risk of refrigerant leakage.

[0014] In one 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, then the state of the backup power supply is determined to be the second state.

[0015] This configuration provides another way to determine the status of the backup power supply based on its voltage and charging time. This second status can include conditions related to the lifespan of the backup power supply, such as its expiration date. Determining the second status helps to promptly alert users when the backup power supply reaches the end of its lifespan, thereby reducing the risk of refrigerant leakage.

[0016] In one 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 the second set value, then the state of the backup power supply is determined to be the third state.

[0017] This configuration provides another way to determine the status of the backup power supply based on its voltage and charging time. The third status can include the backup power supply being fully charged, or the backup power supply having sufficient power to allow the refrigerant piping to switch to a non-flowing state.

[0018] In one technical solution of the above method, the method includes: outputting a prompt message corresponding to the status of the backup power supply.

[0019] This configuration allows users to better monitor the status of backup power.

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

[0021] As can be seen, in this embodiment, when the power supply fails, it determines whether the backup power supply can switch the refrigerant pipeline to a non-flowing state, and outputs a prompt message when the backup power supply cannot switch the refrigerant pipeline to a non-flowing state, so that the user can handle the situation in a timely manner.

[0022] In one 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-flowing state according to the operating parameters", if the backup power supply can enable the refrigerant pipeline to switch to a non-flowing state, then the flow state of the refrigerant pipeline is determined at least according to the operating parameters.

[0023] This configuration allows users to monitor the refrigerant pipeline's flow status in a timely manner, enabling them to promptly address any unexpected situations (such as valve jamming) that occur during the refrigerant pipeline's transition to a non-flowing state, thus preventing refrigerant leaks.

[0024] A second aspect of the present invention provides a computer-readable storage medium adapted to store a plurality of program codes adapted to be loaded and run by a processor to perform the air conditioner operation monitoring method as described in any of the preceding embodiments.

[0025] A third aspect of the present invention provides a computer device, the computer device including a memory and a processor, the memory being adapted to store a plurality of program codes, the program codes being executed by the processor to implement the air conditioner operation monitoring method as described in any of the preceding claims.

[0026] It is understood that the computer-readable storage medium and the computer device have all the technical effects of the air conditioner operation monitoring method described in any of the foregoing claims, and will not be repeated here. Attached Figure Description

[0027] The disclosure of this invention will become more readily understood with reference to the accompanying drawings. It will be readily understood by those skilled in the art that these drawings are for illustrative purposes only and are not intended to limit the scope of protection of this invention. Furthermore, similar numbers in the drawings are used to denote similar components, wherein:

[0028] Figure 1 This 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 This is a flowchart of a method according to an embodiment of the present invention. Detailed Implementation

[0030] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0031] The present invention first provides a method for monitoring the operation of an air conditioner. The air conditioner may include a power supply and a backup power supply. In the event of a power failure, the backup power supply can release electrical energy so that the refrigerant piping of the air conditioner can be switched to a non-flowing state using the electrical energy.

[0032] Figure 1A schematic diagram of the circuit structure of an air conditioner for which an air conditioner operation monitoring method is applied is shown in one embodiment. The air conditioner can be a household air conditioner, such as a wall-mounted unit, a floor-standing unit, or a ducted unit, or a commercial multi-split air conditioning system, or other air conditioning systems.

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

[0034] The main controller 3 can output control signals to the valve actuator 4, thereby causing the valve actuator 4 to control the valve M in the refrigerant circuit of the air conditioner to operate. Similarly, in the case of a multi-split air conditioning system, the main controller 3 can refer to a controller that can control all the air conditioners in the air conditioning system, or it can refer to a controller that can control one or a group of air conditioners in the air conditioning system, and the same applies to the valve actuator 4.

[0035] Power supply 1 can be connected to the power grid and output 12V DC power through transformer 5 to power the main controller 3, valve actuator 4, etc. Obviously, the output of transformer 5 is not limited to 12V DC power; those skilled in the art can reasonably configure the output of transformer 5 according to actual power requirements. Power supply 1 failure refers to power supply 1 malfunctioning due to power outage, loss of power, or insufficient power quality. Power supply 1 being powered on is the opposite.

[0036] The backup power supply 2 may include one or more charging capacitors. The advantage of using capacitors as backup power supply 2 is that capacitors charge extremely quickly, ensuring that the backup power supply 2 is rapidly fully charged when the main power supply 1 is powered on, thus minimizing the possibility of the backup power supply 2 being undercharged when the main power supply 1 fails. 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 valve actuator 4. For example, assuming the main controller 3 and valve actuator 4 require 12V DC power, the rated voltage of the backup power supply 2 should be greater than or equal to 12V, such as 15V or 16V. Obviously, those skilled in the art can also choose to use other structural forms of backup power supply 2 according to actual usage requirements, such as choosing rechargeable batteries (e.g., lithium batteries) as backup power supply 2.

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

[0038] As an example, power supply 1 can be connected to relay coil 6. A normally closed contact 7 can be provided on the connection path between backup power supply 2 and main controller 3 and valve actuator 4. This normally closed contact 7 is connected to relay coil 6. When power supply 1 fails, relay coil 6 is de-energized, and normally closed contact 7 closes, allowing backup power supply 2 to supply power to main controller 3 and valve actuator 4. When power supply 2 is energized, relay coil 6 is energized, and normally closed contact 7 opens, allowing power supply 1 to charge backup power supply 2.

[0039] In this connection configuration, when power supply 1 is powered on, it can automatically charge backup power supply 2; conversely, when power supply 1 is powered off, backup power supply 2 can automatically release electrical energy. Obviously, the connection method between power supply 1 and backup power supply 2 is not limited to this. For example, backup power supply 2 can also be connected to power supply 1 via a diode structure to achieve the above functions. Those skilled in the art can choose according to actual usage requirements.

[0040] Furthermore, the normally closed contact 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 containing components such as the main controller 3 and the valve actuator 4, and at least one normally closed contact 7 is connected in parallel with the charging resistor 8, which 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, causing the charging resistor 8 to be short-circuited, thereby preventing it from draining the backup power supply 2. When the backup power supply 2 is being charged, the normally closed contact 7 is open, allowing the charging resistor 8 to be connected to the circuit, preventing inrush current during charging that could cause the capacitor of the backup power supply 2 to break down.

[0041] Furthermore, a voltage detection circuit 9 can be provided at both ends of the backup power supply 2. The voltage detection circuit 9 can be used to monitor the voltage of the backup power supply 2. A device for measuring voltage, such as a voltmeter, can 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 prompting function such as a display screen, an alarm, or an indicator light. In the case of a commercial multi-split air conditioning system, the prompting device 10 may be installed at the host computer of the air conditioning system.

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

[0044] Figure 2 A flowchart of a method according to an embodiment of the present invention is shown, with reference to Figure 2 The method of this invention includes:

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

[0046] Step S202: If the power supply is energized, determine the status of the backup power supply based on the operating parameters.

[0047] As can be seen, in this embodiment, the status of the backup power supply is determined when the power supply is powered (that is, when the power supply is charging the backup power supply). As a result, the user can more accurately grasp the status of the backup power supply, such as whether the backup power supply is fully charged or whether the backup power supply has malfunctioned. Therefore, when the backup power supply is in an abnormal state, timely action can be taken (such as repairing or replacing the backup power supply 2), avoiding the situation where the power supply fails 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 based on the state of the normally closed contact 7 described above, or the state of the power supply 1 can be determined based on the voltage at both ends of the power supply 1, etc., without limitation.

[0049] The operating parameters of the backup power supply 2 may include parameters related to its operating status, such as voltage and current. These operating parameters can be obtained by setting a detection structure (such as the voltage detection circuit 9 mentioned above) in the air conditioner's circuit structure. When the power supply is powered, the status of the backup power supply 2 can be determined based on these operating parameters. Here, "status" may include the power level of the backup power supply 2, its health condition (e.g., capacity, lifespan), and any fault conditions. Those skilled in the art can determine the specific operating parameters required for practical applications, as well as the specific method for determining the status of the backup power supply 2 based on its actual structure and operating mode, according to the backup power supply 2's specific structure and operating mode.

[0050] In one optional implementation, 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. 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 can also choose to perform the above steps at regular intervals. In this case, the time interval can be fixed or not. For example, when the power supply 2 has not yet finished charging, the above steps can be performed at relatively short time intervals, and when the power supply 2 has finished charging, the above steps can be performed at relatively long time intervals.

[0052] In one possible implementation, the operating parameters may include the voltage of the backup power supply. This configuration provides an optional operating parameter. 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 it stores. Therefore, the voltage of the backup power supply 2 can effectively reflect its state. For example, if the voltage of the backup power supply 2 is increasing, it can be determined that the backup power supply 2 is charging. If the voltage of the backup power supply 2 stabilizes near its rated voltage, or if the voltage of the backup power supply 2 reaches a value greater than the supply voltage, it can be determined that the backup power supply 2 is fully charged. If the voltage of the backup power supply 2 shows a decreasing trend (when the supply power supply 1 is powered), it can be determined that the backup power supply 2 is in a fault state. Obviously, those skilled in the art will understand that even when the backup power supply 2 employs other structures, its state can still be determined based on its voltage.

[0053] In one possible implementation, as described above, when the power supply 1 is powered on, 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 supply 2 to jointly determine the state of the backup power supply 2, thereby enabling a more accurate determination of the state of the backup power supply 2.

[0055] In Adoption Figure 1 In the circuit configuration shown, power supply 1 automatically begins charging backup power supply 2 after being powered on. Therefore, the duration of power supply 1 being powered on can be used as the charging duration of backup power supply 2. In other circuit configurations, the time when backup power supply 2 begins charging can be recorded, and the charging duration can be determined based on that time.

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

[0057] In one 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] This configuration provides an optional method for determining the state of the backup power supply based on its voltage and charging time. The first state of the backup power supply 2 can include leakage or other common fault states. This embodiment monitors the fault state of the backup power supply 2, helping users to take timely action in case of a backup power supply 2 failure, such as turning off the air conditioner and replacing the backup power supply 2, to prevent refrigerant leakage. It should be noted that at any point after the charging time exceeds 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 as the first state.

[0059] In one 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 longer 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] This configuration provides another way to determine the status of the backup power supply based on its voltage and charging time. In this embodiment, the second status may include the battery's end-of-life status. This embodiment monitors the end-of-life status of the backup power supply 2, which helps the user to take timely action when the backup power supply 2 reaches the end of its life to avoid refrigerant leakage. Similarly, at any point in time after the charging time exceeds 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 status of the backup power supply 2 can be determined to be the end-of-life status.

[0061] In one 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, the state of the backup power supply can be determined to be the second state.

[0062] This configuration provides another way to determine the state of the backup power supply based on its voltage and charging time. In this embodiment, the third state can include a fully charged state, or a state where the power level is sufficient to support the refrigerant piping switching to different charge levels.

[0063] The set duration mentioned in the above-described embodiments can be related to the time required for the backup power supply 2 to complete charging under normal conditions, such as being set to 5 minutes. The first and second set values ​​can be related to the voltage of the backup power supply 2 in a fully charged state (e.g., 90%, 85%, 80%, 70% of the rated voltage, etc.). Those skilled in the art can freely set these first and second set values ​​according to actual usage requirements, or determine them by performing charge and discharge tests on the backup power supply 2; there are no limitations on this. As an example, assuming the voltage of the backup power supply 2 in a fully charged state should be greater than 12V, then the first set value can be 10V, and the second set value can be 11V.

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

[0065] In one possible implementation, after determining the status of the backup power supply 2, a corresponding prompt message can be output based on the status of the backup power supply. For example, if it is determined that the backup power supply 2 is charging, a prompt message indicating that it is charging is output; if it is determined that the backup power supply 2 has finished charging, a prompt message indicating that it has finished charging is output; if it is determined that the backup power supply 2 has a leakage, a prompt message indicating that the backup power supply 2 has a leakage is output, etc. This prompt message can be perceived by the user, thereby enabling the user to grasp the status of the backup power supply 2 and then take corresponding measures (such as actively shutting down the air conditioner and repairing the backup power supply 2 in the event of a failure) to avoid the situation where the backup power supply 2 cannot support the valve closure when the power supply 1 fails.

[0066] The notification information can be output to a notification device configured with the air conditioner, or a notification device connected to the air conditioner. This notification device can be a display screen, indicator light, sound, alarm, or any other device capable of notifying the user using light and / or sound signals. Alternatively, the notification information can be output to a user terminal, the air conditioner's host computer, or other terminals capable of interacting with the user. Furthermore, the notification device can emit different light / sound signals to display notification information corresponding to different states; for example, different text can be displayed on the screen to show notification information corresponding to different states. Those skilled in the art can choose according to actual usage needs, and there are no limitations on this.

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

[0068] It is understandable that in some special usage scenarios, even if the user has confirmed that the backup power supply 2 is in a normal state using the methods described above, the backup power supply 2 may still fail to support the refrigerant pipeline switching to a non-flowing state when the main power supply 1 fails. For example, when the main power supply 1 fails, the backup power supply 2 may have just started charging (since this is a normal state, the user will not take any action after confirming this state), resulting in insufficient power to support the refrigerant pipeline switching to a non-flowing state. Therefore, in this embodiment, when the main power supply 1 fails, the system determines whether the backup power supply 2 can support the refrigerant pipeline switching to a non-flowing state based on the operating parameters. If the determination result is that the backup power supply 2 cannot support the refrigerant pipeline switching to a non-flowing state, the system outputs a corresponding prompt message so that the user can take timely action, such as manually controlling the valves in the refrigerant pipeline or connecting other power sources to control the valves in the refrigerant pipeline, thereby preventing refrigerant leakage.

[0069] The operating parameters used to determine whether the backup power supply 2 can support the refrigerant piping switching to a non-flowing state can be the same as, or different from, or not entirely the same as, the operating parameters used to determine the state of the backup power supply 2 (in this case, when obtaining the operating parameters in step S201, all possible operating parameters should be obtained together). Those skilled in the art can choose according to actual needs, and there is no limitation thereto.

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

[0071] It's important to note that determining whether the backup power supply can support switching the refrigerant piping to a non-flowing state is only necessary when the refrigerant piping is in a flowing state. Therefore, before performing the step of "determining whether the backup power supply can support switching the refrigerant piping to a non-flowing state based on operating parameters," it's necessary to first determine whether the refrigerant piping is in a flowing state. For example, this can be determined by observing the voltage change trend of the backup power supply 2 after the power supply 1 fails. If the trend includes a decreasing trend, then the refrigerant piping is in a flowing state. Alternatively, one can determine whether the refrigerant piping is in a flowing state based on the air conditioner's operating status before the power supply 1 fails or the valve opening in the refrigerant piping.

[0072] Furthermore, in some embodiments described above, a prompt message corresponding to the state of the backup power supply 2 will be output. In this embodiment, a prompt message indicating that the refrigerant pipeline cannot be switched to the non-flow state will be output. The two can be in the same form (e.g., both can be presented in text form on the display screen of the host computer, user terminal, or other devices, or both can be in the form of sound broadcast or indicator light flashing), or they can be in different forms. For example, the prompt message indicating that the refrigerant pipeline cannot be switched to the non-flow state can be output in a relatively more conspicuous way. Those skilled in the art 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-flowing state based on operating parameters," if the backup power supply can support the refrigerant pipeline to switch to a non-flowing state, the flow status of the refrigerant pipeline can be determined at least based on the operating parameters. This configuration allows users to promptly monitor the flow status of the refrigerant pipeline after the power supply 1 fails. Therefore, if the refrigerant pipeline cannot switch to a non-flowing state due to reasons other than the backup power supply 2 (such as valve jamming), the user can promptly detect and address the issue.

[0074] Similarly, the operating parameters used here can be the same as, different from, or not entirely the same as those used in other steps above. When determining the flow status of the refrigerant piping, you can use only the above operating parameters, or you can combine them with other parameters.

[0075] As an example, operating parameters may include the power outage duration and the voltage of backup power supply 2. Based on the operating parameters and the control steps of valve controller 4, it can be determined that the refrigerant pipeline's flow state has begun to switch when the power outage duration is less than 5 seconds. When the power outage duration is less than a set duration (which can be determined based on the time required for the refrigerant pipeline to switch from its maximum opening to a non-flowing state, such as 100 seconds), and the voltage of backup power supply 2 is between 8V and 12V (this range can be specifically determined based on the power consumption required to close the valve), it can be determined that the refrigerant pipeline is switching to a non-flowing state. When the power outage duration is greater than the set duration, the voltage of backup power supply 2 is between 5V and 8V, and the control steps of valve actuator 4 have reached the set number of steps, it can be determined that the refrigerant pipeline has switched to a non-flowing state.

[0076] Obviously, those skilled in the art can also use other suitable methods to determine the flow status of refrigerant pipelines. For example, an opening monitoring device can be installed at the valve, and the valve status can be monitored based on the opening monitoring device to determine the flow status of the refrigerant pipeline. There are no restrictions on this.

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