[0028] Liquid cooling air conditioning is air conditioning containing a liquid cooling system, in which heat exchange is carried out through cooling liquid, and the processing of abnormal flow state of the cooling liquid is of great significance to the operation reliability of the liquid cooling air conditioning. However, the current liquid cooling air conditioning generally uses mechanical flow switch or pressure difference switch to detect the on-off detection of the cooling liquid, which cannot realize accurate flow state monitoring, thereby resulting in poor cooling liquid flow abnormality processing effect of the liquid cooling air conditioning, and in the scene of small pipe diameter and low flow resistance requirement, the valve piece insertion of the mechanical flow switch will affect the cooling liquid flow resistance, resulting in poor operation reliability of the liquid cooling air conditioning.

[0029] In order to solve the above problems, the present application provides the following abnormality processing scheme of liquid cooling air conditioning, which can effectively improve the cooling liquid flow abnormality processing effect of the liquid cooling air conditioning and improve the operation reliability of the liquid cooling air conditioning.

[0030] The following describes in detail each embodiment of the abnormality processing scheme of liquid cooling air conditioning provided by the present application.

[0031] Figure 1 A flow chart of an abnormality processing method according to an embodiment of the present application is shown. The execution subject of the abnormality processing method can be a control module with processing capability. The control module can be arranged in an air conditioner, a remote controller, a wire controller, a mobile phone, a computer, a smart watch, and other electronic devices such as household appliances, and the control module can at least include a memory and a processor.

[0032] In an embodiment of the present application, the control module as the execution subject of the abnormality processing method is specifically arranged in an air conditioner, and the control module can include a processor and a memory, i.e., the air conditioner includes the processor and the memory, and the memory stores a computer program. Thus, the processor in the air conditioner can read the computer program stored in the memory to execute the method of each embodiment of the present application.

[0033] As shown in Figure 1 The abnormality processing method can include steps S110 to S140.

[0034] Step S110, receiving the inlet and outlet liquid pressures and the liquid pump state in the liquid cooling system;

[0035] Step S120, when the liquid pump state is a running state, calculating the pressure difference of the inlet and outlet liquid pressures;

[0036] Step S130, determining the abnormal flow state of the cooling liquid in the liquid cooling system according to the abnormal pressure range where the pressure difference is located;

[0037] Step S140, executing the preset abnormality processing action corresponding to the abnormal flow state.

[0038] As shown in Figure 2 An example of a liquid cooling air conditioner 200 is shown, which can include a liquid cooling system 210, a fluorine cooling system 220, and an evaporator 230. The liquid cooling system 210 can include an expansion tank 211 (such as an expansion container or a constant pressure water tank for maintaining the pressure baseline of the liquid cooling system), a filter 212, and a liquid pump 213 arranged in sequence on a liquid cooling passage 214, and the liquid cooling passage 214 also passes through the evaporator 230. The fluorine cooling system 220 can include a compressor 222, a condenser 223, an electronic expansion valve 224, and a fan 225 arranged in sequence on a fluorine cooling passage 221, and the fluorine cooling passage 221 also passes through the evaporator 230.

[0039] The liquid inlet pressure sensor 215 can be arranged at the liquid inlet side of the liquid cooling passage 214 of the liquid cooling system 210, and the liquid outlet pressure sensor 216 can be arranged at the liquid outlet side of the liquid cooling passage 214 of the liquid cooling system 210. The liquid inlet pressure of the liquid cooling system can be received in real time through the liquid inlet pressure sensor 215, and the liquid outlet pressure of the liquid cooling system can be received in real time through the liquid outlet pressure sensor 216. The liquid inlet pressure and the liquid outlet pressure are collectively referred to as the inlet and outlet pressure. In addition, the liquid pump state of the liquid pump 213 can also be received in real time, and the liquid pump state can include a running state or a stopped state.

[0040] When the liquid pump state is in the running state, the pressure difference ΔP of the inlet and outlet pressure is calculated, where ΔP = P_out - P_in, P_out is the liquid outlet pressure, and P_in is the liquid inlet pressure. Further, a plurality of abnormal pressure ranges are preset, each of which corresponds to an abnormal flow state of the coolant. When the calculated pressure difference is in a certain abnormal pressure range, the abnormal flow state of the coolant in the liquid cooling system can be determined according to the abnormal pressure range in which the pressure difference is located.

[0041] Further, corresponding preset abnormal handling actions are specified for different abnormal flow states, and the control module executes the preset abnormal handling action corresponding to the determined abnormal flow state this time, so as to timely handle the flow abnormality of the coolant in the liquid cooling system. The preset abnormal handling action includes but is not limited to "playing an abnormal prompt message through voice or screen", "sending an abnormal prompt message to an early warning platform", or "controlling the liquid cooling system to perform fault self-repairing", and the like.

[0042] In this way of the embodiment of the present application, for the liquid cooling air conditioner, the inlet and outlet pressure of the liquid cooling system is received, and when the liquid pump state is in the running state, the abnormal flow state of the coolant in the liquid cooling system is determined according to the abnormal pressure range in which the pressure difference of the inlet and outlet pressure is located. Compared with the mechanical flow switch or the pressure difference switch for detecting the on-off of the coolant, further accurate flow state monitoring can be realized, so as to improve the coolant flow abnormality handling effect of the liquid cooling air conditioner, and in the scene of small pipe diameter and low flow resistance requirement, the coolant flow resistance will not be affected, and the operation reliability of the liquid cooling air conditioner is improved. Therefore, the coolant flow abnormality handling effect of the liquid cooling air conditioner can be effectively improved, and the operation reliability of the liquid cooling air conditioner is improved.

[0043] The following describes Figure 1 Further optional specific embodiments of each step during the abnormal handling of the embodiment are described.

[0044] In an embodiment, the abnormal flow state of the cooling liquid in the liquid cooling system is determined according to the abnormal pressure range in which the pressure difference is located, including: when the pressure difference is located in a first abnormal pressure range, the abnormal flow state is a first abnormal flow state; when the pressure difference is located in 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; and a preset abnormal processing action corresponding to the abnormal flow state is executed, including: a first abnormal prompt action corresponding to the first abnormal flow state is executed, the first abnormal prompt action being used to prompt that the liquid cooling passage is blocked; or a second abnormal prompt action corresponding to the second abnormal flow state is executed, the second abnormal prompt action being used to prompt that the filter is cleaned.

[0045] In this embodiment, when the liquid pump is in a running state, 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, and the sizes of ΔP1 and ΔP2 can be set according to actual conditions, for example, in an example, ΔP1=1.5Mpa and ΔP2=1Mpa.

[0046] Further, when the pressure difference is located in the first abnormal pressure range, the corresponding abnormal flow state is the first abnormal flow state, at this time, the preset abnormal processing action corresponding to the abnormal flow state is specifically "a first abnormal prompt action is executed, the first abnormal prompt action being used to prompt that the liquid cooling passage is blocked", so that relevant personnel can perform repair processing of the liquid cooling passage according to the prompt, so that the cooling liquid flow returns to normal. The first abnormal prompt action can include but is not limited to "voice playing or screen displaying information that the liquid cooling passage is blocked" or "sending information that the liquid cooling passage is blocked to a warning platform" and the like.

[0047] Further, when the pressure difference is located in the second abnormal pressure range, the corresponding abnormal flow state is the second abnormal flow state, at this time, the preset abnormal processing action corresponding to the abnormal flow state is specifically "a second abnormal prompt action is executed, the second abnormal prompt action being used to prompt that the filter is cleaned", so that relevant personnel can clean the filter according to the prompt, so that the cooling liquid flow returns to normal. The second abnormal prompt action can include but is not limited to "voice playing or screen displaying information that the filter is cleaned" or "sending information that the filter is cleaned to a warning platform" and the like.

[0048] In addition, when the pressure difference is in a preset normal range, it is determined that the cooling liquid in the liquid cooling system is in a normal flow state; at this time, the liquid cooling system can be controlled to maintain the current running state to continue running. The preset normal range is lower than the second abnormal pressure range, specifically, the second abnormal pressure range is ΔP2<ΔP≤ΔP1, and the preset normal range is ΔP3<ΔP≤ΔP2. The values of ΔP2 and ΔP3 can be set according to actual conditions. For example, in an example, ΔP2=1Mpa and ΔP3=0.5Mpa.

[0049] In an embodiment, the inlet and outlet liquid pressures include an inlet liquid pressure and an outlet liquid pressure. After receiving the inlet and outlet liquid pressures and the liquid pump state of the liquid cooling system, the method further includes: when the liquid pump state is a stop state, and the inlet liquid pressure or the outlet liquid pressure is less than a first preset pressure, it is determined that there is a cooling liquid deficiency abnormality in the liquid cooling system; and the liquid cooling system is controlled to stop to protect the liquid pump from cavitation.

[0050] In this embodiment, when the liquid pump state is a stop state, if the inlet liquid pressure or the outlet liquid pressure is further less than the first preset pressure, it is determined that there is a cooling liquid deficiency abnormality in the liquid cooling system in the case that the liquid pump stops, that is, the cooling liquid in the liquid cooling system is in an under-liquid state. In this case, the liquid pump has a risk of cavitation, and the liquid cooling system is directly controlled to remain stopped to avoid starting running, so that cavitation protection of the liquid pump can be realized in the case that the liquid pump stops.

[0051] Further, after the liquid cooling system is controlled to remain stopped to avoid starting running, it can be determined in real time whether the inlet liquid pressure or the outlet liquid pressure is restored to be greater than or equal to the first preset pressure. If the inlet liquid pressure or the outlet liquid pressure is restored to be greater than or equal to the first preset pressure, the liquid cooling system can be controlled to normally standby, that is, the liquid cooling system is allowed to start running. The first preset pressure can be set according to actual conditions. For example, in an example, the first preset pressure is equal to 0.2Mpa.

[0052] Further, in an embodiment, the inlet and outlet liquid pressures include an inlet liquid pressure and an outlet liquid pressure. After receiving the inlet and outlet liquid pressures and the liquid pump state of the liquid cooling system, the method further includes: when the liquid pump state is a stop state, and the inlet liquid pressure or the outlet liquid pressure is greater than or equal to a first preset pressure, it is determined that the cooling liquid in the liquid cooling system is full (that is, not lacking cooling liquid), and at this time, the liquid cooling system can be controlled to normally standby.

[0053] In one embodiment, the inlet and outlet hydraulic pressures include an inlet hydraulic pressure and an outlet hydraulic pressure; after receiving the inlet and outlet hydraulic pressures and the pump state in the liquid cooling system, the method further includes: when the pump state is in a running state, and the inlet hydraulic pressure or the outlet hydraulic pressure is less than a second preset pressure, determining that there is a coolant deficiency in the liquid cooling system; controlling the pump to run at a preset speed, the preset speed being lower than a rated speed of the pump; when the inlet hydraulic pressure or the outlet hydraulic pressure is greater than or equal to the second preset pressure, controlling the pump to maintain running at the preset speed; and when the inlet hydraulic pressure or the outlet hydraulic pressure continues to be less than the second preset pressure, controlling the liquid cooling system to shut down and performing a coolant deficiency alarm.

[0054] In this embodiment, when the pump state is in the running state, if the inlet hydraulic pressure or the outlet hydraulic pressure is further less than the second preset pressure, it is determined that there is a coolant deficiency in the liquid cooling system in the case that the pump is running, that is, the coolant in the liquid cooling system is in an underfill state. In this case, the running performance of the liquid cooling system is poor, and then the pump is controlled to run at a preset speed, the preset speed being lower than the rated speed of the pump (in one example, the preset speed = 50%*rated speed, or in other examples, the preset speed = s*rated speed, s being less than 1).

[0055] After the pump is controlled to run at the preset speed, if it is monitored that the inlet hydraulic pressure or the outlet hydraulic pressure is restored to be greater than or equal to the second preset pressure, the pump is controlled to continue running at the preset speed. Conversely, after the pump is controlled to run at the preset speed, if it is monitored that the inlet hydraulic pressure or the outlet hydraulic pressure continues to be less than the second preset pressure and lasts for a preset time, the liquid cooling system is controlled to shut down, and a coolant deficiency alarm is performed (for example, "voice playing or screen displaying information of coolant deficiency" or "sending information of coolant deficiency to an early warning platform", etc.), so as to guarantee the running reliability of the liquid cooling system in the case that the pump is running.
