Description

Technical Field

[0001] This application relates to the field of air conditioning technology, specifically to an anomaly handling method, apparatus, storage medium, and electronic device. Background Technology

[0002] Liquid-cooled air conditioners are air conditioners that include a liquid cooling system. Heat exchange occurs through coolant in this system, and handling abnormal coolant flow patterns is crucial for the operational reliability of liquid-cooled air conditioners. However, current liquid-cooled air conditioners generally use mechanical flow switches or differential pressure switches to detect coolant flow, which cannot achieve precise flow monitoring. This results in poor handling of abnormal coolant flow patterns. Furthermore, in scenarios requiring small pipe diameters and low flow resistance, the insertion of the valve plate in mechanical flow switches can affect coolant flow resistance, further compromising the operational reliability of the liquid-cooled air conditioner.

[0028] Liquid-cooled air conditioners are air conditioners that include a liquid cooling system. Heat exchange occurs through coolant in this system, and handling abnormal coolant flow patterns is crucial for the operational reliability of liquid-cooled air conditioners. However, current liquid-cooled air conditioners generally use mechanical flow switches or differential pressure switches to detect coolant flow, which cannot achieve precise flow monitoring. This results in poor handling of abnormal coolant flow patterns. Furthermore, in scenarios requiring small pipe diameters and low flow resistance, the insertion of the valve plate in mechanical flow switches can affect coolant flow resistance, further compromising the operational reliability of the liquid-cooled air conditioner.

[0029] To address the aforementioned issues, this application provides the following abnormal handling solution for liquid-cooled air conditioners, which can effectively improve the handling of abnormal coolant flow in liquid-cooled air conditioners and enhance their operational reliability.

[0030] The following provides a detailed description of each embodiment of the fault handling scheme for liquid-cooled air conditioners provided in this application.

[0031] Figure 1 A flowchart illustrating an embodiment of an exception handling method according to this application is shown. The execution entity of this exception handling method may be a control module with processing capabilities. The control module may be installed in electronic devices such as air conditioners, remote controls, wired controllers, mobile phones, computers, smartwatches, and other home appliances, and may include at least a memory and a processor.

[0032] In one embodiment of this application, the control module, which serves as the execution subject of the exception handling method, is specifically located in an air conditioner. The control module may include a processor and a memory; that is, the air conditioner includes the processor and the memory, and the memory stores a computer program. Therefore, the processor in the air conditioner can read the computer program stored in the memory to execute the methods of the various embodiments of this application.

[0033] like Figure 1 As shown, the exception handling method may include steps S110 to S140.

[0034] Step S110: Receive the inlet and outlet liquid pressures and the status of the liquid pump in the liquid cooling system;

[0035] Step S120: When the pump is in the running state, calculate the pressure difference between the inlet and outlet liquid pressures;

[0036] Step S130: Determine the abnormal flow state of the coolant in the liquid cooling system based on the abnormal pressure range where the pressure difference is located.

[0037] Step S140: Execute the preset abnormal handling action corresponding to the abnormal flow state.

[0038] like Figure 2 An example of a liquid-cooled air conditioner 200 is shown. The liquid-cooled air conditioner 200 may include a liquid cooling system 210, a refrigerant cooling system 220, and an evaporator 230. The liquid cooling system 210 may include an expansion tank 211 (such as an expansion container or a constant pressure water tank, used to maintain the pressure baseline of the liquid cooling system), a filter 212, and a liquid pump 213, which are sequentially arranged on a liquid cooling passage 214. The liquid cooling passage 214 also communicates through the evaporator 230. The refrigerant cooling system 220 may include a compressor 222, a condenser 223, an electronic expansion valve 224, and a fan 225, which are sequentially arranged on a refrigerant cooling passage 221. The refrigerant cooling passage 221 also communicates through the evaporator 230.

[0039] An inlet pressure sensor 215 can be installed on the inlet side of the liquid cooling passage 214 of the liquid cooling system 210, and an outlet pressure sensor 216 can be installed on the outlet side of the liquid cooling passage 214 of the liquid cooling system 210. The inlet pressure sensor 215 can receive the inlet pressure of the liquid cooling system in real time, and the outlet pressure sensor 216 can receive the outlet pressure of the liquid cooling system in real time. The inlet and outlet pressures include both the inlet and outlet pressures. Furthermore, the status of the liquid pump 213 can be received in real time, which may include whether it is running or stopped.

[0040] When the pump is in operation, calculate the pressure difference ΔP between the inlet and outlet liquid pressures, where ΔP = P_out - P_in and P_out represent the outlet pressure, and P_in represents the inlet pressure. Furthermore, multiple abnormal pressure ranges are pre-defined, each corresponding to an abnormal flow state of the coolant. When the calculated pressure difference falls within a certain abnormal pressure range, the abnormal flow state of the coolant in the liquid cooling system can be determined based on the abnormal pressure range in which the pressure difference occurs.

[0041] Furthermore, corresponding preset anomaly handling actions are specified for different abnormal flow states. The control module executes the preset anomaly handling actions corresponding to the currently determined abnormal flow state, thereby promptly handling the abnormal flow of coolant in the liquid cooling system. These preset anomaly handling actions include, but are not limited to, "playing anomaly prompt messages via voice or screen," "sending anomaly prompt messages to the early warning platform," or "controlling the liquid cooling system to perform autonomous fault repair," etc.

[0042] In this embodiment of the application, for liquid-cooled air conditioners, by receiving the inlet and outlet liquid pressures in the liquid cooling system, and with the liquid pump in operation, the abnormal flow state of the coolant in the liquid cooling system is determined based on the abnormal pressure range of the pressure difference between the inlet and outlet liquid pressures. Compared to mechanical flow switches or differential pressure switches for coolant on / off detection, this method achieves more precise flow state monitoring, thereby improving the handling effect of abnormal coolant flow in liquid-cooled air conditioners. Moreover, it does not affect the coolant flow resistance in scenarios with small pipe diameters and low flow resistance requirements, thus improving the operational reliability of liquid-cooled air conditioners. Therefore, overall, it can effectively improve the handling effect of abnormal coolant flow in liquid-cooled air conditioners and enhance their operational reliability.

[0043] The following description Figure 1 Further optional specific embodiments are provided for each step performed during exception handling in the example implementation.

[0044] In one embodiment, determining the abnormal flow state of the coolant in the liquid cooling system based on the abnormal pressure range of the pressure difference includes: when the pressure difference is within a first abnormal pressure range, the abnormal flow state is a first abnormal flow state; when the pressure difference is within a second abnormal pressure range, the abnormal flow state is a second abnormal flow state; wherein the first abnormal pressure range is higher than the second abnormal pressure range; correspondingly, executing a preset abnormal handling action corresponding to the abnormal flow state includes: executing a first abnormal prompt action corresponding to the first abnormal flow state, the first abnormal prompt action being used to indicate that the liquid cooling passage is blocked; or, executing a second abnormal prompt action corresponding to the second abnormal flow state, the second abnormal prompt action being used to indicate that the filter needs cleaning.

[0045] In this embodiment, when the liquid pump is in operation, the set abnormal pressure range specifically includes a first abnormal pressure range and a second abnormal pressure range, wherein the first abnormal pressure range is higher than the second abnormal pressure range. Specifically, the first abnormal pressure range is ΔP1 < ΔP; the second abnormal pressure range is ΔP2 < ΔP ≤ ΔP1. The magnitudes of ΔP1 and ΔP2 can be set according to actual conditions. For example, in one example, ΔP1 = 1.5 MPa and ΔP2 = 1 MPa.

[0046] Furthermore, when the pressure difference is within the first abnormal pressure range, the corresponding abnormal flow state is designated as the first abnormal flow state. In this case, the pre-defined abnormal handling action corresponding to the abnormal flow state is specifically "execute the first abnormality alert action, which is used to indicate that the liquid cooling passage is blocked." Relevant personnel can then repair the blockage based on this alert, thereby restoring normal coolant flow. The first abnormality alert action may include, but is not limited to, "playing a voice message or displaying a screen message indicating that the liquid cooling passage is blocked" or "sending a message indicating that the liquid cooling passage is blocked to the early warning platform."

[0047] Furthermore, when the pressure difference falls within the second abnormal pressure range, the corresponding abnormal flow state is designated as the second abnormal flow state. In this case, the pre-defined abnormal handling action corresponding to the abnormal flow state is executed as "execute the second abnormality prompt action, which prompts the user to clean the filter." This allows relevant personnel to clean the filter based on the prompt, thereby restoring normal coolant flow. The second abnormality prompt action may include, but is not limited to, "playing a voice message or displaying a screen message about cleaning the filter" or "sending a message about cleaning the filter to the early warning platform."

[0048] Furthermore, when the pressure difference is within the preset normal range, it is determined that the coolant in the liquid cooling system is in a normal flow state; at this time, the liquid cooling system can be controlled to maintain its current operating state and continue to operate. Specifically, the preset normal range is lower than the second abnormal pressure range. The second abnormal pressure range is ΔP2 < ΔP ≤ ΔP1, and the preset normal range is ΔP3 < ΔP ≤ ΔP2. The magnitudes of ΔP2 and ΔP3 can be set according to actual conditions. For example, in one example, ΔP2 = 1 MPa and ΔP3 = 0.5 MPa.

[0049] In one embodiment, the inlet and outlet liquid pressures include inlet pressure and outlet pressure; after receiving the inlet and outlet liquid pressures and the status of the liquid pump in the liquid cooling system, the method further includes: when the liquid pump is in a stopped state and the inlet or outlet pressure is less than a first preset pressure, it is determined that there is a coolant shortage in the liquid cooling system; the liquid cooling system is shut down to protect the liquid pump from cavitation.

[0050] In this embodiment, when the liquid pump is in a stopped state, if the inlet or outlet pressure is further less than the first preset pressure, it is determined that there is a coolant shortage abnormality in the liquid cooling system "when the liquid pump is stopped". The coolant shortage abnormality means that the coolant in the liquid cooling system is not full. In this case, the liquid pump is at risk of cavitation. Directly controlling the liquid cooling system to remain stopped and avoid starting it can achieve cavitation protection for the liquid pump when it is stopped.

[0051] Furthermore, after controlling the liquid cooling system to remain shut down to prevent startup, it is possible to determine in real time whether the inlet or outlet pressure has recovered to a level greater than or equal to the first preset pressure. If the inlet or outlet pressure recovers to a level greater than or equal to the first preset pressure, the liquid cooling system can be kept in normal standby mode, which means that the liquid cooling system is allowed to start running. The first preset pressure can be set according to the actual situation. For example, in one example, the first preset pressure is equal to 0.2 MPa.

[0052] Furthermore, in one embodiment, the inlet and outlet liquid pressures include inlet liquid pressure and outlet liquid pressure; after receiving the inlet and outlet liquid pressures and the status of the liquid pump in the liquid cooling system, the method further includes: when the liquid pump is in a stopped state and the inlet or outlet liquid pressure is greater than or equal to a first preset pressure, it is determined that the liquid cooling system is full of coolant (i.e., there is no shortage of coolant), and at this time, the liquid cooling system can be controlled to standby normally.

[0053] In one embodiment, the inlet and outlet liquid pressures include inlet pressure and outlet pressure; after receiving the inlet and outlet liquid pressures and the liquid pump status in the liquid cooling system, the method further includes: when the liquid pump is in operation and the inlet or outlet pressure is less than a second preset pressure, determining that there is a coolant shortage abnormality in the liquid cooling system; controlling the liquid pump to reduce its speed to a preset speed, which is lower than the rated speed of the liquid pump; when the inlet or outlet pressure is greater than or equal to the second preset pressure, controlling the liquid pump to maintain the preset speed; when the inlet or outlet pressure continues to be less than the second preset pressure, controlling the liquid cooling system to shut down and issuing a coolant shortage alarm.

[0054] In this embodiment, when the liquid pump is in operation, if the inlet or outlet pressure is further lower than the second preset pressure, it is determined that there is a coolant shortage abnormality in the liquid cooling system "while the liquid pump is running". The coolant shortage abnormality means that the coolant in the liquid cooling system is not full. Under this condition, the operating performance of the liquid cooling system deteriorates, and the liquid pump is then controlled to operate at a preset speed, which is lower than the rated speed of the liquid pump (in one example, the preset speed = 50% * rated speed, or in other examples, the preset speed = s * rated speed, where s is less than 1).

[0055] After the liquid pump is reduced to a preset speed, if the inlet or outlet pressure recovers to a level greater than or equal to a second preset pressure, the liquid pump can be maintained at that preset speed. Conversely, after the liquid pump is reduced to a preset speed, if the inlet or outlet pressure remains below the second preset pressure for a preset duration, the liquid cooling system is shut down, and a coolant shortage alarm is triggered (e.g., a voice message or screen display indicating a coolant shortage, or a message sent to an early warning platform). This ensures the reliability of the liquid cooling system while the liquid pump is running.

[0056] To facilitate better implementation of the exception handling method provided in the embodiments of this application, the embodiments of this application also provide an exception handling device based on the above exception handling method. The meanings of the terms used are the same as in the above exception handling method, and specific implementation details can be found in the descriptions in the method embodiments.

[0059] In one embodiment, the inlet and outlet liquid pressures include inlet pressure and outlet pressure; after receiving the inlet and outlet liquid pressures and the liquid pump status in the liquid cooling system, the diagnostic module is configured to: determine that there is a coolant shortage abnormality in the liquid cooling system when the liquid pump status is the stopped state and the inlet pressure or the outlet pressure is less than a first preset pressure; the execution module is configured to: control the liquid cooling system to shut down to provide cavitation protection for the liquid pump.

[0060] In one embodiment, the inlet and outlet liquid pressures include inlet pressure and outlet pressure; after receiving the inlet and outlet liquid pressures and the liquid pump status in the liquid cooling system, the diagnostic module is configured to: determine that there is a coolant shortage abnormality in the liquid cooling system when the liquid pump status is the operating state and the inlet pressure or the outlet pressure is less than a second preset pressure; the execution module is configured to: control the liquid pump to reduce its operating speed to a preset speed, the preset speed being lower than the rated speed of the liquid pump; control the liquid pump to maintain the preset speed when the inlet pressure or the outlet pressure is greater than or equal to the second preset pressure; control the liquid cooling system to shut down and issue a coolant shortage alarm when the inlet pressure or the outlet pressure continues to be less than the second preset pressure.
