Energy storage liquid cooling system and its high-temperature start-up method, electronic equipment and storage medium

[0001] This application claims priority to Chinese Patent Application No. 202411646550.0, filed with the Chinese Patent Office on November 18, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of energy storage technology, specifically to an energy storage liquid cooling system and its high-temperature start-up method, electronic equipment, and storage medium. Background Technology

[0003] When using a liquid cooling system to dissipate heat from an energy storage container, the low-pressure side refrigerant of the compressor in the liquid cooling system absorbs the heat from the energy storage container and dissipates the heat outward through the high-pressure side refrigerant of the compressor, thereby reducing the temperature of the energy storage container. Invention Overview

[0004] However, in high-temperature environments, the temperature of the energy storage container itself may be too high, causing the low-pressure side refrigerant of the compressor to absorb too much heat, resulting in excessively high refrigerant pressure on the high-pressure side of the compressor, triggering the compressor's high-temperature protection mechanism, and causing the liquid cooling system to fail to start at high temperature.

[0005] In related technologies, a more heat-resistant refrigerant is typically used in liquid cooling systems to prevent high-temperature start-up failures. For example, replacing R410a refrigerant with the more heat-resistant R134a refrigerant. However, using a more heat-resistant refrigerant requires corresponding replacements of other components in the liquid cooling system, and the power consumption of the liquid cooling system is also higher, increasing the cost of the liquid cooling system.

[0006] In a first aspect, this application provides a high-temperature start-up method for an energy storage liquid cooling system. The energy storage liquid cooling system includes a refrigeration circuit and a liquid cooling circuit connected in parallel via a heat exchanger. A liquid storage tank is provided in the liquid cooling circuit. The liquid cooling outlet of the energy storage container is connected to the heat exchanger and the liquid storage tank, respectively. The high-temperature start-up method for the energy storage liquid cooling system includes:

[0007] Upon receiving a power-on command for the energy storage container, obtain the ambient temperature of the energy storage container;

[0008] Obtain the liquid supply temperature of the liquid cooling circuit;

[0009] When the ambient temperature is greater than or equal to the ambient temperature threshold and the liquid supply temperature is greater than or equal to the first liquid supply temperature threshold, the target pipeline is controlled to be open, and the liquid cooling outlet of the energy storage container is connected to the liquid storage tank through the target pipeline.

[0010] Start the compressor in the refrigeration circuit.

[0011] Secondly, this application also provides an energy storage liquid cooling system, which includes a refrigeration circuit and a liquid cooling circuit connected in parallel through a heat exchanger. A liquid storage tank is provided in the liquid cooling circuit, and the liquid cooling outlet of the energy storage container is connected to the heat exchanger and the liquid storage tank respectively.

[0012] Thirdly, this application also provides a high-temperature start-up device for an energy storage liquid cooling system, the high-temperature start-up device for the energy storage liquid cooling system comprising:

[0013] The first acquisition module is used to acquire the ambient temperature of the energy storage container when it receives a power-on command for the energy storage container.

[0014] The second acquisition module is used to acquire the liquid supply temperature of the liquid cooling circuit;

[0015] The valve regulating module is used to control the target pipeline to open when the ambient temperature is greater than or equal to the ambient temperature threshold and the liquid supply temperature is greater than or equal to the first liquid supply temperature threshold. The liquid cooling outlet of the energy storage container is connected to the liquid storage tank through the target pipeline.

[0016] The start-up control module is used to start the compressor in the refrigeration circuit.

[0017] Fourthly, this application also provides an electronic device, which includes a processor and a memory, wherein the memory stores a computer program configured to be executed by the processor to implement the high-temperature start-up method of the energy storage liquid cooling system as described above.

[0018] Fifthly, this application also provides a computer-readable storage medium storing a computer program configured to be executed by a processor to implement the high-temperature start-up method of the energy storage liquid cooling system as described above.

[0019] Sixthly, this application also provides a computer program product, including a computer program or instructions, which are executed by a processor to implement the high-temperature start-up method of the energy storage liquid cooling system as described in any of the above claims. Beneficial effects

[0020] This application adds a pipe between the liquid cooling outlet of the energy storage container and the liquid storage tank. When the compressor needs to be started at high temperature, the pipe is first controlled to open so that part of the refrigerant flowing out of the energy storage container does not flow through the heat exchanger and directly enters the liquid storage tank. This avoids excessive heat absorption by the low-pressure side refrigerant of the compressor and excessively high refrigerant pressure on the high-pressure side of the compressor, thereby achieving high-temperature start-up of the energy storage liquid cooling system. Moreover, the cost of the energy storage liquid cooling system is lower. Attached Figure Description

Embodiments of the present invention

[0028] To ensure high-temperature startup of the energy storage liquid cooling system while reducing its cost, this application proposes a possible implementation of an energy storage liquid cooling system, its high-temperature startup method, electronic equipment, and storage medium. This involves adding a pipe between the liquid cooling outlet of the energy storage container and the storage tank. When a high-temperature startup of the compressor is required, this pipe is first opened to allow some of the refrigerant flowing from the energy storage container to bypass the heat exchanger and directly enter the storage tank. This avoids excessive heat absorption by the low-pressure side refrigerant and excessively high refrigerant pressure on the high-pressure side of the compressor, thereby achieving high-temperature startup of the energy storage liquid cooling system at a lower cost.

[0029] In a first aspect, this application provides an energy storage liquid cooling system 1 as a possible implementation. Specifically, referring to FIG1, FIG1 is a schematic diagram of the overall structure of the energy storage liquid cooling system 1. In FIG1, the energy storage liquid cooling system 1 may include a refrigeration circuit 20 and a liquid cooling circuit 30 connected in parallel through a heat exchanger 10.

[0030] The heat exchanger 10 may be, for example, a plate heat exchanger. The heat exchanger 10 includes a first heat exchange pipe and a second heat exchange pipe connected in parallel, through which the refrigerant in the first heat exchange pipe and the refrigerant in the second heat exchange pipe can exchange heat. The first heat exchange pipe is located in the refrigeration circuit 20, and the second heat exchange pipe is located in the liquid cooling circuit 30.

[0031] In the refrigeration circuit 20, in addition to the first heat exchange pipe, a compressor 21 is also included, which is connected to the first heat exchange pipe. The refrigeration circuit 20 may also include components such as a condenser 22, a condenser fan 23, a dryer filter 24, and an expansion valve 25. In the refrigeration circuit 20, the heat exchanger 10 acts as an evaporator, used to absorb heat using the refrigerant, while the condenser 22 uses the refrigerant to dissipate heat to the outside. The condenser fan 23 drives airflow, facilitating the dissipation of heat from the condenser 22 into the outside air. The refrigeration principle of the refrigeration circuit 20 is similar to that of an air conditioner and will not be elaborated upon here.

[0032] In the liquid-cooled circuit 30, in addition to the second heat exchange pipe, a liquid storage tank 31 is also included. The liquid-cooled outlet 321 of the energy storage container 32 is connected to the heat exchanger 10 and the liquid storage tank 31, respectively. Specifically, the liquid-cooled outlet 321 of the energy storage container 32 is connected to the inlet of the second heat exchange pipe in the heat exchanger 10 and a liquid inlet of the liquid storage tank 31, respectively. The outlet of the second heat exchange pipe in the heat exchanger 10 is also connected to the liquid inlet of the liquid storage tank 31. Furthermore, in the liquid storage tank 31, the liquid inlet connected to the outlet of the second heat exchange pipe in the heat exchanger 10 and the liquid inlet connected to the liquid-cooled outlet 321 of the energy storage container 32 can be the same liquid inlet or different liquid inlets, which is not limited here.

[0033] The pipe used to connect the liquid cooling outlet 321 of the energy storage container 32 to the liquid inlet of the storage tank 31 is called the target pipe 311. A target valve 33 is connected in series in the target pipe 311, and the target valve 33 can be, for example, a proportional two-way valve. The target valve 33 can be used to control the opening and closing of the target pipe 311, as well as to control the current opening degree of the target pipe 311 (the current opening degree is the current opening degree when the target pipe 311 is open, and the opening degree of the target pipe 311 refers to the ratio of the cross-sectional area through which the fluid passes in the target pipe 311 to the total cross-sectional area of ​​the target pipe 311). Therefore, by controlling the opening of the target pipe 311, the high-temperature start-up method of the energy storage liquid cooling system can be implemented to ensure that the energy storage liquid cooling system 1 can start up at high temperature.

[0034] In the liquid cooling circuit 30, the outlet of the liquid storage tank 31 is connected to the liquid cooling inlet of the energy storage container 32 to facilitate the circulation of refrigerant in the liquid cooling circuit 30. Furthermore, a liquid supply pump 34 is installed in the pipe connecting the outlet of the liquid storage tank 31 to the liquid cooling inlet of the energy storage container 32 in the liquid cooling circuit 30. The liquid supply pump 34 is used to drive the flow of refrigerant in the liquid cooling circuit 30.

[0035] Secondly, this application provides a high-temperature start-up method for an energy storage liquid cooling system. The high-temperature start-up method for the energy storage liquid cooling system is executed based on the energy storage liquid cooling system. Specifically, referring to Figure 2, based on the implementation shown in Figure 1, Figure 2 is a flowchart illustrating a possible implementation of the high-temperature start-up method for the energy storage liquid cooling system. In Figure 2, the high-temperature start-up method for the energy storage liquid cooling system may include:

[0036] 201. When a power-on command is received for the energy storage container, the ambient temperature of the energy storage container is obtained.

[0037] In possible implementations of this application, the start-up command for the energy storage container refers to a command used to instruct the opening of the energy storage container, which can be triggered manually or automatically. The ambient temperature of the energy storage container refers to the temperature of the environment in which the energy storage container is located, such as at least one of the external ambient temperature and the internal ambient temperature of the energy storage container body.

[0038] In a possible implementation of this application, after obtaining the ambient temperature of the energy storage container, the process may further include: when the ambient temperature is greater than or equal to an ambient temperature threshold, it indicates that if the compressor is started at this time, the compressor may be operating under high-temperature start-up conditions. Therefore, step 202 is executed to obtain the liquid supply temperature of the liquid cooling circuit. Conversely, when the ambient temperature is less than the ambient temperature threshold, it indicates that if the compressor is started at this time, high-temperature start-up conditions can be avoided. Therefore, the compressor can be started directly to achieve the liquid cooling heat dissipation effect of the energy storage liquid cooling system.

[0039] In addition, when the ambient temperature is greater than or equal to the ambient temperature threshold, the liquid supply pump in the energy storage liquid cooling system can be started to drive the refrigerant circulation in the liquid cooling circuit to utilize the refrigerant for liquid cooling heat dissipation.

[0040] 202. Obtain the liquid supply temperature of the liquid cooling circuit.

[0041] In possible implementations of this application, the liquid supply temperature of the liquid cooling circuit refers to the refrigerant temperature at locations such as the liquid supply pump outlet, the liquid cooling inlet of the energy storage container, and the liquid cooling outlet of the energy storage container.

[0042] 203. When the ambient temperature is greater than or equal to the ambient temperature threshold, control the target pipeline to conduct.

[0043] In a possible implementation of this application, the ambient temperature threshold and the first liquid supply temperature threshold are preset values. For example, the ambient temperature threshold could be 50°C and the first liquid supply temperature threshold could be 40°C. When the ambient temperature is greater than or equal to the ambient temperature threshold and the liquid supply temperature is greater than or equal to the first liquid supply temperature threshold, it indicates that if the compressor is started at this time, the compressor will be in a high-temperature start-up condition, and the energy storage liquid cooling system may fail to start at a high temperature. Therefore, the target pipe can be controlled to allow some of the refrigerant flowing out of the liquid cooling outlet of the energy storage container to flow directly from the target pipe connecting the liquid cooling outlet of the energy storage container and the liquid inlet of the storage tank to the storage tank without passing through the heat exchanger, and then flow back from the storage tank to the energy storage container. It can be seen that by controlling the target pipe, the refrigerant flow rate that needs to flow through the second heat exchange pipe can be reduced. In this way, the heat exchanger needs to exchange between the first heat exchange pipe and the second heat exchange pipe will also be reduced, and the heat absorbed by the low-pressure side refrigerant of the compressor will also be reduced, thereby lowering the high-pressure side refrigerant pressure of the compressor.

[0044] In a possible implementation of this application, after step 203, the following steps may be included: starting the condenser fan of the condenser in the refrigeration circuit; after the condenser fan is turned on, step 204 is then executed to accelerate the rate at which the condenser dissipates heat to the outside through the operation of the condenser fan, thereby reducing the high-pressure side refrigerant pressure and the low-pressure side refrigerant pressure of the compressor, so that the energy storage liquid cooling system can be started up at high temperature more quickly.

[0045] In a possible implementation of this application, after obtaining the liquid supply temperature of the liquid cooling circuit, it may further include: when the liquid supply temperature is less than the first liquid supply temperature threshold, it indicates that if the compressor is started at this time, the compressor can avoid being in a high-temperature start-up condition, so the compressor can be started directly to achieve the liquid cooling heat dissipation effect of the energy storage liquid cooling system.

[0046] 204. Start the compressor in the refrigeration circuit.

[0047] In one possible implementation of this application, starting the compressor after the target pipeline is opened can prevent the refrigerant pressure on the high-pressure side of the compressor from being too high, thereby ensuring that the compressor can start successfully under high-temperature conditions.

[0048] As can be seen, in the possible implementation of this application, by adding a pipe between the liquid cooling outlet of the energy storage container and the liquid storage tank, when the compressor needs to be started at high temperature, the pipe is first controlled to be open so that part of the refrigerant flowing out of the energy storage container does not flow through the heat exchanger and directly enters the liquid storage tank, thereby avoiding excessive heat absorption by the low-pressure side refrigerant of the compressor and excessively high pressure of the high-pressure side refrigerant of the compressor, thus achieving high-temperature start-up of the energy storage liquid cooling system, and the cost of the energy storage liquid cooling system is lower.

[0049] In a possible implementation of this application, as shown in Figure 3, based on the implementation shown in Figure 2, after starting the compressor in the refrigeration circuit, it may further include:

[0050] 301. Reacquire the liquid supply temperature of the liquid cooling circuit.

[0051] In a possible implementation of this application, after starting the compressor, the energy storage liquid cooling system needs to be gradually adjusted to a normal state to restore its original liquid cooling heat dissipation effect. Therefore, after starting the compressor, the liquid supply temperature of the liquid cooling circuit can be re-acquired, and the opening and closing of the target pipeline can be controlled based on the re-acquired liquid supply temperature.

[0052] 302. If the liquid supply temperature is lower than the second liquid supply temperature threshold, control the target pipeline to close.

[0053] In a possible implementation of this application, a second liquid supply temperature threshold is also provided, which is less than or equal to the first liquid supply temperature threshold. For example, the second liquid supply temperature threshold could be 35°C. If the re-acquired liquid supply temperature is less than the second liquid supply temperature threshold, it indicates that the energy storage liquid cooling system has completed its high-temperature startup. Therefore, the target pipe can be shut down to restore the original liquid cooling effect of the energy storage liquid cooling system. It can be seen that by setting the second liquid supply temperature threshold to be less than or equal to the first liquid supply temperature threshold, the high-temperature protection mechanism of the compressor can be avoided from being triggered due to the shut-down of the target pipe, thus preventing the compressor from shutting down again after the target pipe is closed.

[0054] 303. Control the batteries in the energy storage container to enter the operating state.

[0055] In a possible implementation of this application, after the target pipeline is closed, the energy storage container can be controlled to start operating. For example, the batteries in the energy storage container can be controlled to enter the operating state so that the batteries in the energy storage container can start charging and discharging, thereby realizing the charging and discharging function of the energy storage container.

[0056] In a possible implementation of this application, after reacquiring the liquid supply temperature of the liquid cooling circuit, the following may be included: if the reacquiring liquid supply temperature is greater than or equal to a second liquid supply temperature threshold, maintain the current conduction opening of the target pipeline.

[0057] In a possible implementation of this application, after reacquiring the liquid supply temperature of the liquid cooling circuit, the method may further include: if the reacquisitioned liquid supply temperature is greater than or equal to a second liquid supply temperature threshold, adjusting the current opening degree of the target pipe based on the liquid supply temperature to gradually restore the original liquid cooling heat dissipation effect of the energy storage liquid cooling system. The current opening degree of the target pipe is positively correlated with the reacquisitioned liquid supply temperature. It is understood that since the reacquisitioned liquid supply temperature will gradually decrease due to heat exchange in the heat exchanger, the current opening degree of the target pipe can also gradually decrease, thereby gradually restoring the original liquid cooling heat dissipation effect of the energy storage liquid cooling system.

[0058] In a possible implementation of this application, as shown in Figure 4, based on the implementation shown in Figure 2 or Figure 3, controlling the target pipeline to open when the ambient temperature is greater than or equal to an ambient temperature threshold and the liquid supply temperature is greater than or equal to a first liquid supply temperature threshold may include:

[0059] 401. When the ambient temperature is greater than or equal to the ambient temperature threshold and the liquid supply temperature is greater than or equal to the first liquid supply temperature threshold, obtain the target conduction opening degree of the target pipeline.

[0060] 402. Control the target pipeline opening according to the target opening degree.

[0061] In a possible implementation of this application, the target conduction opening of the target pipeline refers to the target value of the conduction opening of the target pipeline (i.e., the target opening when the target pipeline is conducting). This target conduction opening can be a preset value, such as 100% or 90%, but in order to minimize the risk of high-temperature start-up failure of the energy storage liquid cooling system, the target conduction opening is generally set to 100%.

[0062] Of course, the target conduction opening can be determined based on the liquid supply temperature, rather than a preset value. Specifically, obtaining the target conduction opening of the target pipe can include: obtaining the difference between the liquid supply temperature and a first liquid supply temperature threshold; and determining the target conduction opening of the target pipe based on the difference. The target conduction opening of the target pipe is positively correlated with the difference, meaning that the higher the liquid supply temperature, the higher the target conduction opening. This ensures that the energy storage liquid cooling system has a certain degree of liquid cooling heat dissipation effect while avoiding high-temperature start-up failure.

[0063] In a possible implementation of this application, the refrigerant may be R410a type refrigerant.

[0064] Thirdly, based on the high-temperature start-up method for an energy storage liquid cooling system, this application may provide a high-temperature start-up device for an energy storage liquid cooling system, which is used to perform the steps in any possible implementation of the high-temperature start-up method for the energy storage liquid cooling system. For example, the high-temperature start-up device for the energy storage liquid cooling system may include:

[0065] The first acquisition module is used to acquire the ambient temperature of the energy storage container when it receives a power-on command for the energy storage container.

[0066] The second acquisition module is used to acquire the liquid supply temperature of the liquid cooling circuit;

[0067] The valve regulating module is used to control the target pipeline to open when the ambient temperature is greater than or equal to the ambient temperature threshold and the liquid supply temperature is greater than or equal to the first liquid supply temperature threshold. The liquid cooling outlet of the energy storage container is connected to the liquid storage tank through the target pipeline.

[0068] The start-up control module is used to start the compressor in the refrigeration circuit.

[0069] Fourthly, a possible implementation of this application provides an electronic device that integrates a high-temperature start-up device for any of the energy storage liquid cooling systems provided in any of the possible implementations of this application. The electronic device includes a processor and a memory, the memory storing a computer program configured to be executed by the processor to implement the high-temperature start-up method for the energy storage liquid cooling system as described in any of the possible implementations above, for example:

[0070] Upon receiving a start-up command for the energy storage container, the system acquires the ambient temperature of the energy storage container; acquires the liquid supply temperature of the liquid cooling circuit; when the ambient temperature is greater than or equal to the ambient temperature threshold and the liquid supply temperature is greater than or equal to the first liquid supply temperature threshold, the system controls the target pipeline to open, and the liquid cooling outlet of the energy storage container is connected to the liquid storage tank through the target pipeline; and starts the compressor in the refrigeration circuit.
