Description

Technical Field

[0001] This application relates to the field of energy storage equipment technology, and more specifically, to a temperature control component for an energy storage electrical cabinet, an energy storage electrical cabinet, and a control method thereof. Background Technology

[0002] Currently, in related technologies, energy storage containers are equipped with components that are highly sensitive to ambient temperature, such as switching power supplies and UPS (Uninterruptible Power Supply) backup batteries. Because localized overheating within the electrical cabinets of energy storage containers can halve the lifespan of components, and excessively low temperatures may cause condensation on the surfaces of electrical components, reducing the safety of the energy storage container, the cooling, heating, and dehumidification performance of the electrical cabinets affects the lifespan and performance of the electrical components installed inside. Summary of the Invention

[0003] This application aims to at least address the technical problem in the related art that devices such as switching power supplies and UPS backup batteries inside energy storage containers have high requirements for ambient temperature, and existing electrical cabinets cannot meet the temperature control and dehumidification needs for cooling, heating and dehumidification, thus affecting the lifespan and performance of electrical devices assembled inside energy storage containers.

[0004] Therefore, the first aspect of this application provides a temperature control component for an energy storage electrical cabinet.

[0005] The second aspect of this application proposes an energy storage electrical cabinet.

[0006] The third aspect of this application proposes an energy storage container.

[0007] The fourth aspect of this application proposes a control method for an energy storage electrical cabinet.

[0008] The fifth aspect of this application proposes a control device for an energy storage electrical cabinet.

[0009] The sixth aspect of this application proposes a computer-readable storage medium.

[0010] The seventh aspect of this application proposes an energy storage electrical cabinet.

[0011] In view of this, this application provides a temperature control component for an energy storage electrical cabinet, used for temperature regulation of the energy storage electrical cabinet. The temperature control component includes: a cooling circulation loop storing coolant; a refrigeration circulation loop storing refrigerant; an evaporator connected between the cooling circulation loop and the refrigeration circulation loop for heat exchange between them; a first heat exchange component connected to the refrigeration circulation loop; and a second heat exchange component connected to the cooling circulation loop. When the temperature control component meets a first preset condition, the cooling circulation loop is activated; when the temperature control component meets a second preset condition, both the cooling circulation loop and the refrigeration circulation loop are activated simultaneously, and the first and second heat exchange components are in cooling mode to dissipate heat and lower the temperature of the energy storage electrical cabinet.

[0012] The temperature control component for the energy storage electrical cabinet provided in this application is used to regulate the temperature of the energy storage electrical cabinet. The component includes a cooling circulation loop, a refrigeration circulation loop, an evaporator, a first heat exchange component, and a second heat exchange component. The cooling circulation loop stores coolant, meaning coolant flows through it. The coolant flow facilitates heat exchange with the components it passes through, thereby achieving cooling, heating, or dehumidification. The refrigeration circulation loop stores refrigerant, meaning refrigerant flows through it. The refrigerant flow facilitates heat exchange with the components it passes through, thereby achieving cooling, heating, or dehumidification. The refrigeration circulation loop can be used for heat dissipation, heating, and dehumidification.

[0013] The evaporator connects the cooling and refrigeration cycles, facilitating heat exchange between them. In other words, the cooling cycle connects to the refrigeration cycle via the evaporator, meaning they share a common evaporator. This allows for heat exchange between the two cycles. For instance, in cooling mode, if the cooling cycle's capacity is insufficient, the refrigeration cycle can transfer energy to it through the evaporator to maintain its cooling capacity. Similarly, in heating mode, if the refrigeration cycle's capacity is insufficient, the cooling cycle can transfer heat to it through the evaporator to maintain its heating capacity. The evaporator acts as an energy exchanger between the cooling and refrigeration cycles.

[0014] The first heat exchanger is connected in series in the refrigeration cycle loop, allowing refrigerant to flow within it. Due to its large heat exchange area, the refrigerant flow can effectively exchange heat with the refrigerant. The second heat exchanger is connected in series in the cooling cycle loop, allowing coolant to flow within it. Again, due to its large heat exchange area, the coolant flow can effectively exchange heat with the refrigerant.

[0015] When the temperature control component of the energy storage electrical cabinet meets the first preset condition, the cooling circulation loop is activated. When the temperature control component meets the second preset condition, both the cooling circulation loop and the refrigeration circulation loop are activated simultaneously. The first and second heat exchange components are in refrigeration mode to dissipate heat and cool the energy storage electrical cabinet. The first preset condition can be understood as the ambient temperature inside the energy storage electrical cabinet approaching a first limit value, causing the temperature inside the cabinet to rise and potentially affecting the performance of electrical components in the energy storage unit, such as the switching power supply and UPS backup battery. The second preset condition can be understood as the ambient temperature inside the energy storage electrical cabinet approaching a second limit value, but the first limit value is less than the second limit value. That is, when the ambient temperature inside the energy storage electrical cabinet exceeds a set threshold, and the temperature of the energy storage electrical cabinet is already affecting the normal operation of the electrical components in the energy storage unit, the cooling circulation loop is activated for cooling and heat dissipation. In other words, when the ambient temperature inside the energy storage electrical cabinet continues to rise, and the cooling circulation loop alone cannot meet the cooling demand, the refrigeration circulation loop is activated for cooling and heat dissipation. Cooling and heat dissipation are achieved through the combined action of the cooling circulation loop and the refrigeration circulation loop. Because the refrigeration cycle circuit is equipped with a compressor, the operation of the compressor can reduce the temperature inside the energy storage electrical cabinet, effectively achieving cooling and heat dissipation.

[0016] The temperature control component of the energy storage electrical cabinet according to the above technical solution of this application may also have the following additional technical features:

[0017] In some technical solutions, optionally, the first preset condition is Ta > T2-2 or Tu > T1-2, and the second preset condition is Ta > T4-2 or Tu > T3-2; wherein, Tu is the body temperature of the external energy storage battery module of the energy storage electrical cabinet, Ta is the ambient temperature of the energy storage electrical cabinet, T1 is the first threshold temperature of the body temperature of the energy storage battery module, T3 is the second threshold temperature of the body temperature of the energy storage battery module, T2 is the first critical value of the ambient temperature of the energy storage electrical cabinet, T4 is the second critical value of the ambient temperature of the energy storage electrical cabinet, and T1 < T3 < T2 < T4.

[0018] In this technical solution, the first preset condition is Ta > T2-2 or Tu > T1-2, and the second preset condition is Ta > T4-2 or Tu > T3-2; where Tu is the body temperature of the external energy storage battery module of the energy storage electrical cabinet, Ta is the ambient temperature of the energy storage electrical cabinet, T1 is the first threshold temperature of the energy storage battery module, T3 is the second threshold temperature of the energy storage battery module, T2 is the first critical value of the ambient temperature of the energy storage electrical cabinet, and T4 is the second critical value of the ambient temperature of the energy storage electrical cabinet, and T1 < T3 < T2 < T4. By precisely controlling the start-up timing of the temperature control component of the energy storage electrical cabinet, effective management and control of the temperature of the energy storage battery module inside the electrical cabinet and energy storage container are achieved, improving the stability and reliability of the energy storage system.

[0019] In some technical solutions, optionally, the cooling circulation loop includes a first reversing valve, a first regulating valve, and a heating element. The first reversing valve includes a first port, a second port, and a third port. The first port is connected to one end of the evaporator, the second port is connected to one end of the first regulating valve, and the third port is connected to one end of the heating element. The pipe between the second port and the other end of the evaporator is a first flow path. The first regulating valve and the second heat exchange assembly are connected in series in the first flow path. The pipe between the third port and the other end of the evaporator is a second flow path. The heating element is connected in series in the second flow path. The first flow path and the second flow path are arranged in parallel. When the temperature control assembly of the energy storage electrical cabinet satisfies Ta > T2-2 or Tu > T1-2, the first port, the second port, and the third port of the first reversing valve are open, and the opening degree of the first regulating valve is at the first opening degree, and the first flow path and the second flow path are connected. When the temperature control assembly of the energy storage electrical cabinet satisfies Ta > T2 or Tu > T1, the opening degree of the first regulating valve is at the second opening degree, which is greater than the first opening degree.

[0020] In this technical solution, the cooling circulation loop includes a first reversing valve, a first regulating valve, and a heating element. The first reversing valve includes a first port, a second port, and a third port. The first port is connected to one end of the evaporator, the second port is connected to one end of the first regulating valve, and the third port is connected to one end of the heating element. The pipe between the second port and the other end of the evaporator forms a first flow path. The first regulating valve and a second heat exchange assembly are connected in series in the first flow path. The pipe between the third port and the other end of the evaporator forms a second flow path. The heating element is connected in series in the second flow path. The first and second flow paths are connected in parallel. By setting the first reversing valve and the first regulating valve, the flow rate of the cooling medium (coolant) can be divided and adjusted, thereby achieving precise control of the heat dissipation effect in different areas within the electrical cabinet. This configuration not only improves heat dissipation efficiency but also makes the heat dissipation device more flexible and adaptable. It can provide targeted heat dissipation based on the heat generation and heat dissipation requirements of different components within the energy storage unit's electrical cabinet, improving energy utilization efficiency and heat dissipation effect.

[0021] In some technical solutions, optionally, the refrigeration cycle loop includes a second reversing valve, a second regulating valve, a condenser, and a compressor. The second reversing valve includes a fourth port, a fifth port, and a sixth port. The fourth port is connected to one end of the condenser, the fifth port is connected to one end of the second regulating valve, and the sixth port is connected to one end of the evaporator. The pipe between the fifth port and one end of the evaporator forms a third flow path. The second regulating valve and the first heat exchange component are connected in series in the third flow path. The pipe between the sixth port and one end of the evaporator forms a fourth flow path. The third and fourth flow paths are connected in parallel. When the temperature control component of the energy storage electrical cabinet meets Ta > T4-2 or Tu > T3-2, the refrigeration... The cooling cycle loop starts, and the first regulating valve is at the second opening degree. At the same time, the cooling cycle loop starts, and the second regulating valve is at the third opening degree. When the temperature control component of the energy storage electrical cabinet meets the condition that Ta > T4 or Tu > T3, the opening degree of the second regulating valve is at the fourth opening degree, which is greater than the third opening degree. Specifically, if the temperature control component of the energy storage electrical cabinet is in the working state, the fourth, fifth, and sixth ports of the second reversing valve are open, and the third and fourth flow paths are connected. If the temperature control component of the energy storage electrical cabinet is in the standby state, the fourth and fifth ports of the second reversing valve are connected, the sixth port is closed, the third flow path is connected, and the fourth flow path is closed.

[0022] In this technical solution, the refrigeration cycle loop includes a second reversing valve, a second regulating valve, a condenser, and a compressor. The second reversing valve includes a fourth port, a fifth port, and a sixth port. The fourth port is connected to one end of the condenser, the fifth port is connected to one end of the second regulating valve, and the sixth port is connected to one end of the evaporator. The pipe between the fifth port and the evaporator forms a third flow path. The second regulating valve and the first heat exchange component are connected in series in the third flow path, and the pipe between the sixth port and the evaporator forms a fourth flow path. The third and fourth flow paths are connected in parallel. By setting up the second reversing valve and the second regulating valve, the refrigerant can be diverted and its flow rate adjusted, thereby achieving precise control of the heat dissipation effect in different areas within the electrical cabinet. This setup not only improves heat dissipation efficiency but also makes the heat dissipation device more flexible and adaptable. It allows for targeted heat dissipation based on the heat generation and heat dissipation requirements of different components within the energy storage unit's electrical cabinet, improving energy utilization efficiency and heat dissipation effect. The dual heat dissipation mode design of the refrigeration cycle loop and the cooling cycle loop enables precise temperature control within the energy storage electrical cabinet.

[0023] In some technical solutions, the temperature control component of the energy storage electrical cabinet may optionally include a heating module. The heating module is connected to the first flow path and located between the first reversing valve and the first regulating valve. When the temperature control component of the energy storage electrical cabinet satisfies Tu < T5, the first port and the second port are opened, the first flow path is connected, and the opening degree of the first regulating valve is at the second opening degree. The heating module is started, and the second heat exchange component is in heating mode to heat the energy storage electrical cabinet. Here, T5 is the low temperature threshold of the energy storage battery component.

[0024] In this technical solution, the temperature control component of the energy storage electrical cabinet also includes a heating module. The heating module is connected to the first flow path and positioned between the first reversing valve and the first regulating valve. When the temperature control component of the energy storage electrical cabinet satisfies Tu < T5, the first and second ports are opened, the first flow path is connected, and the opening degree of the first regulating valve is at the second opening degree. At this time, the heating module is activated, and the second heat exchange component is in heating mode to heat the energy storage electrical cabinet. By setting the heating module in the first flow path, when the temperature of the energy storage battery module is lower than the low-temperature threshold, that is, when the temperature of the energy storage battery module is lower than the normal preset operating temperature, the heating mode of the temperature control component of the energy storage electrical cabinet is activated to ensure the normal operating temperature of the energy storage battery module. The temperature control component of the energy storage electrical cabinet achieves precise temperature control inside the energy storage electrical cabinet by flexibly adjusting the working state of the cooling circulation loop and the heating module.

[0025] In some technical solutions, optionally, when the temperature control component of the energy storage electrical cabinet satisfies Tb>Td, the fourth and fifth ports are opened, the third flow path is connected, and the opening degree of the second regulating valve is at the second opening degree. The first heat exchange component is in dehumidification mode to dehumidify the energy storage electrical cabinet, where Tb is the ambient humidity of the energy storage electrical cabinet and Td is the dew point humidity.

[0026] In this technical solution, when the temperature control component of the energy storage electrical cabinet satisfies Tb > Td, the fourth and fifth ports are open, the third flow path is connected, and the second regulating valve is at its second opening degree. The first heat exchange component is in dehumidification mode to dehumidify the energy storage electrical cabinet. By controlling the opening of the fourth and fifth ports of the second reversing valve and the opening degree of the second regulating valve, the flow rate of refrigerant entering the first heat exchange component can be adjusted, thereby controlling the dehumidification effect of the first heat exchange component. When the ambient humidity Tb inside the energy storage electrical cabinet is higher than the dew point humidity Td, it indicates that the air humidity inside the electrical cabinet is high, and the dehumidification mode needs to be activated. At this time, by adjusting the second reversing valve and the second regulating valve, the refrigerant flows through the first heat exchange component, and the cooling effect of the first heat exchange component condenses the moisture in the air into water droplets and discharges them, thereby achieving the purpose of dehumidification.

[0027] According to a second aspect of this application, an energy storage electrical cabinet is also proposed, comprising: an energy storage electrical cabinet temperature control component as described in any of the above embodiments; and a cabinet body, wherein a first heat exchange component is disposed within the cabinet body at the bottom of the cabinet body, and a second heat exchange component is disposed within the cabinet body above the first heat exchange component; a first sensor disposed within the cabinet body for detecting ambient temperature and ambient humidity; a second sensor disposed within the cabinet body for detecting the temperature of the energy storage battery component; and a fan assembly disposed within the cabinet body on the side close to the second heat exchange component for supplying air to the first heat exchange component and the second heat exchange component.

[0028] The energy storage electrical cabinet provided in this application has all the beneficial effects of the energy storage electrical cabinet temperature control component as it includes any of the above-mentioned technical solutions, and will not be described in detail here.

[0029] In addition, the energy storage electrical cabinet also includes a cabinet body, a first sensor, a second sensor, and a fan assembly. The first heat exchange assembly is located inside the cabinet body at the bottom, and the second heat exchange assembly is located inside the cabinet body above the first heat exchange assembly. The first sensor is located inside the cabinet body and is used to detect ambient temperature and humidity. The second sensor is located inside the cabinet body and is used to detect the temperature of the energy storage battery components within the energy storage unit. The fan assembly is located inside the cabinet body, near the second heat exchange assembly, and is used to supply air to both the first and second heat exchange components.

[0030] In some technical solutions, the energy storage electrical cabinet may optionally include: a collector plate, which is located in the cabinet body at the bottom of the first heat exchange component, for receiving condensate dripping from the first heat exchange component; and a drain pipe, which is located at the bottom of the cabinet body, for draining the condensate collected on the collector plate from the cabinet body.

[0031] In this technical solution, the energy storage electrical cabinet also includes a manifold and a drain pipe. The manifold is located inside the cabinet, at the bottom of the first heat exchange component, and is used to collect condensate dripping from the first heat exchange component. The drain pipe is located at the bottom of the cabinet and is used to drain the condensate collected on the manifold out of the cabinet. By adding the manifold and drain pipe, the drainage system inside the energy storage electrical cabinet is further optimized, ensuring a dry and clean environment inside the cabinet.

[0032] According to a third aspect of this application, an energy storage container is also proposed, comprising: an energy storage electrical cabinet as described above; and a housing, wherein the energy storage electrical cabinet is disposed on one side of the housing; and an energy storage battery assembly, wherein the energy storage battery assembly is disposed on the other side of the housing and is disposed opposite to the first heat exchange assembly, for providing electrical energy to the outside.

[0033] The energy storage container provided in this application includes the energy storage electrical cabinet of the above-mentioned technical solution, and therefore has all the beneficial effects of the energy storage electrical cabinet, which will not be repeated here.

[0034] In addition, the energy storage container also includes a housing and an energy storage battery module. The energy storage electrical cabinet is located on one side of the housing, and the energy storage battery module is located on the other side of the housing, opposite to the first heat exchange component. The energy storage battery module is used to provide power to the outside environment.

[0035] According to the fourth aspect of this application, a control method for an energy storage electrical cabinet is also proposed for controlling the temperature control component of the energy storage electrical cabinet as described above. The control method includes: detecting the ambient temperature and humidity inside the energy storage electrical cabinet; in cooling mode, when the temperature control component of the energy storage electrical cabinet satisfies Ta > T2-2 or Tu > T1-2, starting the cooling circulation loop and opening the first, second, and third ports of the first reversing valve, adjusting the opening degree of the first regulating valve to the first opening degree, and controlling the conduction of the first and second flow paths; when the temperature control component of the energy storage electrical cabinet satisfies Ta > T2 or Tu > T1, adjusting the opening degree of the first regulating valve to the second opening degree; and when the temperature control component of the energy storage electrical cabinet satisfies Ta > T4-2 or Tu > T3-2, starting the cooling circulation loop. The first regulating valve is adjusted to the second opening degree, and the refrigeration cycle loop is started. The second regulating valve is adjusted to the third opening degree. When the temperature control component of the energy storage electrical cabinet meets the conditions of Ta > T4 or Tu > T3, the opening degree of the second regulating valve is adjusted to the fourth opening degree. If the temperature control component of the energy storage electrical cabinet is in the working state, the fourth, fifth, and sixth ports of the second reversing valve are opened simultaneously to control the third and fourth flow paths to be connected. If the temperature control component of the energy storage electrical cabinet is in the standby state, the fourth and fifth ports of the second reversing valve are opened, and the sixth port of the second reversing valve is closed to control the third flow path to be connected and the fourth flow path to be closed.

[0036] In this technical solution, the control method of the energy storage electrical cabinet achieves precise control of the ambient temperature and humidity inside the energy storage electrical cabinet by adjusting the working state of the cooling circulation loop and the refrigeration circulation loop, as well as the connection mode between the first reversing valve and the second reversing valve, and the opening degree of the first regulating valve and the second regulating valve.

[0037] In some technical solutions, the control method may optionally include: in heating mode, when the temperature control component of the energy storage electrical cabinet meets the condition Tu < T5, opening the first port and the second port of the cooling circulation loop, controlling the first flow path to be connected, adjusting the opening degree of the first regulating valve to the second opening degree, and controlling the heating module to start.

[0038] In this technical solution, during heating mode, when the temperature control component of the energy storage electrical cabinet detects that the body temperature Tu of the energy storage battery module is lower than the low-temperature threshold T5 of the energy storage battery module, it opens the first and second ports of the cooling circulation loop, making the first flow path conductive. This ensures that the air inside the cabinet can circulate properly during heating to improve heating efficiency. The opening degree of the first regulating valve is adjusted to the second opening degree. The flow rate of the cooling medium in the cooling circulation loop is controlled, thereby regulating the temperature inside the cabinet. The heating module is activated to provide heat to raise the temperature inside the cabinet. When the body temperature Tu of the energy storage battery module is lower than T5, activating the heating module can quickly raise the temperature inside the cabinet, and the evaporation of moisture in the air through heating also helps to reduce humidity.

[0039] In some technical solutions, the control method may optionally include: in dehumidification mode, when the temperature control component of the energy storage electrical cabinet satisfies Tb>Td, opening the fourth and fifth ports of the refrigeration cycle loop, controlling the third flow path to be open, adjusting the opening degree of the second regulating valve to the second opening degree, and controlling the fan component to reduce the wind speed to the preset wind speed.

[0040] In this technical solution, under dehumidification mode, the energy storage electrical cabinet is ensured to effectively dehumidify when the humidity is too high, while maintaining an appropriate temperature.

[0041] According to the fifth aspect of this application, a control device for an energy storage electrical cabinet is also proposed. The control device includes a processor and a memory. The processor is used to execute a computer program stored in the memory to implement the steps of the control method for the energy storage electrical cabinet as described in any of the technical solutions of the fourth aspect.

[0042] According to a sixth aspect of this application, a computer-readable storage medium is also proposed, on which a computer program is stored, which, when executed by a processor, implements the steps of the control method for the energy storage electrical cabinet as described in any of the technical solutions of the fourth aspect.

[0043] According to the seventh aspect of this application, an energy storage electrical cabinet is also proposed, comprising: a control device as described in the fifth aspect; and / or a computer-readable storage medium as described in the sixth aspect.

[0063] An embodiment of this application provides a temperature control component 100 for an energy storage electrical cabinet 200, which is used to regulate the temperature of the energy storage electrical cabinet 200. The temperature control component 100 includes: a cooling circulation loop 110, in which coolant is stored; a refrigeration circulation loop 120, in which refrigerant is stored; and an evaporator 122, which is connected between the cooling circulation loop 110 and the refrigeration circulation loop 120 and is used to exchange heat between the cooling circulation loop 110 and the refrigeration circulation loop 120. The first heat exchange component 124 is connected to the refrigeration cycle loop 120; the second heat exchange component 126 is connected to the cooling cycle loop 110; when the temperature control component 100 of the energy storage electrical cabinet meets the first preset condition, the cooling cycle loop 110 is started; when the temperature control component 100 of the energy storage electrical cabinet meets the second preset condition, the cooling cycle loop 110 and the refrigeration cycle loop 120 are started simultaneously, and the first heat exchange component 124 and the second heat exchange component 126 are in cooling mode to dissipate heat and cool down the energy storage electrical cabinet 200.

[0064] Specifically, such as Figure 1 As shown, the temperature control component 100 of the energy storage electrical cabinet is used to regulate the temperature of the energy storage electrical cabinet 200. The temperature control component 100 includes a cooling circulation loop 110, a refrigeration circulation loop 120, an evaporator 122, a first heat exchange component 124, and a second heat exchange component 126. The cooling circulation loop 110 stores coolant, meaning coolant flows through it. The coolant flow in the cooling circulation loop 110 facilitates heat exchange with the components it passes through, thereby achieving cooling, heating, or dehumidification. The refrigeration circulation loop 120 stores refrigerant, meaning refrigerant flows through it. The refrigerant flow in the refrigeration circulation loop 120 facilitates heat exchange with the components it passes through, thereby achieving cooling, heating, or dehumidification. The refrigeration circulation loop 120 can be used for heat dissipation, heating, and dehumidification.

[0065] Evaporator 122 is connected between cooling loop 110 and refrigeration loop 120 for heat exchange between them. In other words, cooling loop 110 is connected to refrigeration loop 120 via evaporator 122. Alternatively, it can be understood that cooling loop 110 and refrigeration loop 120 share a single evaporator 122, allowing heat exchange between them. For example, in cooling mode, if the cooling capacity of cooling loop 110 is insufficient, refrigeration loop 120 can transfer energy to cooling loop 110 through evaporator 122 to maintain its cooling capacity. In heating mode, if the heating capacity of refrigeration loop 120 is insufficient, cooling loop 110 can transfer heat to refrigeration loop 120 through evaporator 122 to maintain its heating capacity. Evaporator 122 acts as an energy exchanger between cooling loop 110 and refrigeration loop 120.

[0066] The first heat exchange component 124 is connected in series in the refrigeration cycle loop 120, allowing refrigerant to flow within it. Due to the large heat exchange area of ​​the first heat exchange component 124, the heat exchange airflow can effectively exchange heat with it. The second heat exchange component 126 is connected in series in the cooling cycle loop 110, allowing coolant to flow within it. Due to the large heat exchange area of ​​the second heat exchange component 126, the heat exchange airflow can effectively exchange heat with it.

[0067] When the temperature control component 100 of the energy storage electrical cabinet meets the first preset condition, the cooling circulation loop 110 is activated. When the temperature control component 100 of the energy storage electrical cabinet meets the second preset condition, the cooling circulation loop 110 and the refrigeration circulation loop 120 are activated simultaneously, and the first heat exchange component 124 and the second heat exchange component 126 are in refrigeration mode to dissipate heat and cool the energy storage electrical cabinet 200. The first preset condition can be understood as the ambient temperature inside the energy storage electrical cabinet 200 approaching a first limit value, causing the temperature inside the energy storage electrical cabinet 200 to rise, which will affect the performance of electrical components in the energy storage container 300, such as switching power supplies and UPS backup batteries. The second preset condition can be understood as the ambient temperature inside the energy storage electrical cabinet 200 approaching a second limit value, and the first limit value being less than the second limit value. When the ambient temperature inside the energy storage electrical cabinet 200 exceeds a set threshold, and this temperature rise affects the normal operation of the electrical components in the energy storage unit 300, cooling circulation loop 110 is activated for cooling and heat dissipation. Conversely, if the ambient temperature inside the energy storage electrical cabinet 200 continues to rise, and cooling circulation loop 110 alone is insufficient to meet the cooling demand, cooling circulation loop 120 is activated for cooling and heat dissipation. Both cooling circulation loops 110 and 120 work together to achieve cooling and heat dissipation. Since cooling circulation loop 120 is equipped with compressor 150, the operation of compressor 150 can reduce the temperature inside the energy storage electrical cabinet 200, effectively achieving cooling and heat dissipation.

[0068] Specifically, in related technologies, the electrical cabinet of an energy storage container houses components such as switching power supplies and UPS backup batteries, which are highly sensitive to ambient temperature. The heat dissipation performance of the electrical cabinet affects the lifespan and performance of the electrical components installed inside. Furthermore, as the energy density of energy storage containers gradually increases, the space within the electrical cabinet is compressed, resulting in high-power and heat-sensitive components being installed in a limited space, making it impossible to avoid mutual interference in heat exchange efficiency between components of different power levels. Localized overheating within the electrical cabinet can halve the lifespan of electrical components, while excessively low temperatures may cause condensation on the surface of electrical components, reducing the safety of the energy storage container. Simultaneously, backup batteries cannot operate normally in environments below 0°C. Based on the ambient temperature range required by the UPS backup batteries, the electrical cabinet needs to be equipped with temperature control equipment capable of maintaining the UPS ambient temperature between 0 and 40°C, while also providing dehumidification functionality to prevent condensation from affecting the interior of the cabinet. In related technologies, an industrial air conditioner is usually mounted on the wall of the battery cabinet to meet the needs of temperature control and dehumidification. However, industrial air conditioners have high operating power and need to be externally mounted on the container, which increases the power consumption of auxiliary power sources, reduces the system's RTE (Run-Time Environment), and affects the overall aesthetics of the energy storage container.

[0069] In response to this issue, such as Figure 1As shown, this application provides a temperature control component 100 for an energy storage electrical cabinet. The temperature control component 100 achieves efficient and energy-saving temperature control by combining a cooling circulation loop 110 and a refrigeration circulation loop 120. The cooling circulation loop 110 stores coolant, which exchanges heat with the components inside the electrical cabinet through its flow, thereby enabling temperature control of electrical components such as the switching power supply and UPS backup battery in the energy storage unit 300 through the energy storage electrical cabinet 200, i.e., heat dissipation, heating, or dehumidification. The refrigeration circulation loop 120 stores refrigerant, which further enables cooling, heating, or dehumidification through its flow.

[0070] Heat exchange occurs between the two circulation loops via an evaporator 122, which acts as an energy exchanger. In cooling mode, when the cooling capacity of the cooling circulation loop 110 is insufficient, the cooling circulation loop 120 can transfer energy to the cooling circulation loop 110 through the evaporator 122, ensuring overall cooling performance. Similarly, in heating mode, the two circulation loops can also exchange heat through the evaporator 122, ensuring sufficient heating capacity.

[0071] In addition, the energy storage electrical cabinet temperature control assembly 100 also includes a first heat exchange assembly 124 and a second heat exchange assembly 126. The first heat exchange assembly 124 is connected to the refrigeration cycle loop 120, and achieves efficient heat exchange with the heat exchange airflow through its large heat exchange area. The second heat exchange assembly 126 is connected to the cooling cycle loop 110, and also has a large heat exchange area, which can effectively improve the heat exchange efficiency.

[0072] During operation, when the ambient temperature inside the energy storage electrical cabinet 200 approaches the set first limit, the cooling circulation loop 110 will activate first to perform initial heat dissipation and cooling, while the second heat exchange component 126 will be in cooling mode. When the ambient temperature approaches the higher second limit, both the cooling circulation loop 110 and the cooling circulation loop 120 will activate simultaneously, with the first heat exchange component 124 and the second heat exchange component 126 both in cooling mode, working together to dissipate heat and cool the energy storage electrical cabinet 200.

[0073] Through this design, the temperature control component 100 of the energy storage electrical cabinet in this application can not only effectively control the temperature inside the energy storage electrical cabinet 200, ensuring the normal operation and long life of electrical components, but also has a dehumidification function, avoiding the impact of condensate on the cabinet interior. At the same time, compared with traditional industrial air conditioners, the temperature control component 100 has lower operating power and a higher energy efficiency ratio, significantly reducing auxiliary power consumption and improving system RTE efficiency. Furthermore, its compact design avoids the impact of external equipment on the overall aesthetics of the energy storage container, providing a highly efficient, energy-saving, and aesthetically pleasing solution for temperature control and dehumidification of the energy storage container electrical cabinet.

[0074] In some embodiments, optionally, the first preset condition is Ta > T2-2 or Tu > T1-2, and the second preset condition is Ta > T4-2 or Tu > T3-2; wherein, Tu is the body temperature of the external energy storage battery assembly 320 of the energy storage electrical cabinet 200, Ta is the ambient temperature of the energy storage electrical cabinet 200, T1 is the first threshold temperature of the body temperature of the energy storage battery assembly 320, T3 is the second threshold temperature of the body temperature of the energy storage battery assembly 320, T2 is the first critical value of the ambient temperature of the energy storage electrical cabinet 200, T4 is the second critical value of the ambient temperature of the energy storage electrical cabinet 200, and T1 < T3 < T2 < T4.

[0075] Specifically, the first preset condition is Ta > T2-2 or Tu > T1-2, and the second preset condition is Ta > T4-2 or Tu > T3-2; where Tu is the body temperature of the external energy storage battery module 320 of the energy storage electrical cabinet 200, Ta is the ambient temperature of the energy storage electrical cabinet 200, T1 is the first threshold temperature of the energy storage battery module 320, T3 is the second threshold temperature of the energy storage battery module 320, T2 is the first critical value of the ambient temperature of the energy storage electrical cabinet 200, and T4 is the second critical value of the ambient temperature of the energy storage electrical cabinet 200, and T1 < T3 < T2 < T4. By precisely controlling the start-up timing of the energy storage electrical cabinet temperature control component 100, effective management and control of the temperature of the electrical cabinet and the internal energy storage battery module 320 of the energy storage container 300 are achieved, improving the stability and reliability of the energy storage system.

[0076] Specifically, when the ambient temperature Ta of the energy storage electrical cabinet 200 is higher than the first critical value T2 of the ambient temperature of the energy storage electrical cabinet 200 minus a preset safety margin (e.g., 2°C), or when the body temperature Tu of the energy storage battery module 320 is higher than the first threshold temperature T1 of the energy storage battery module 320 minus a preset safety margin (e.g., 2°C), the first preset condition is met, meaning that the energy storage battery module 320 is about to be in an abnormal operating environment. At this time, the system will activate the cooling circulation loop 110 to begin the initial heat dissipation and cooling process to maintain the energy storage electrical cabinet 200 and the battery module inside the energy storage container 300 within a relatively safe temperature range.

[0077] When the ambient temperature Ta of the energy storage electrical cabinet 200 further increases, exceeding the second critical value T4 minus a preset safety margin (e.g., 2°C), or when the body temperature Tu of the energy storage battery module 320 exceeds the second threshold T3 minus a preset safety margin (e.g., 2°C), the second preset condition is met, meaning the energy storage battery module 320 is in an abnormal operating environment. At this time, the system will simultaneously activate the cooling circulation loop 110 and the refrigeration circulation loop 120. The first heat exchange component 124 and the second heat exchange component 126 will simultaneously be in refrigeration mode, working together to provide more powerful heat dissipation and cooling for the energy storage electrical cabinet 200, ensuring that the energy storage electrical cabinet 200 and the battery modules inside the energy storage container 300 can operate normally, and avoiding performance degradation or damage to the energy storage battery module 320 due to excessive temperature.

[0078] Specifically, the design of this application takes into account the temperature requirements of the energy storage electrical cabinet 200 and the internal battery modules of the energy storage container 300 under different operating conditions. By precisely setting the temperature threshold and critical value, as well as a reasonable safety margin, energy consumption can be minimized while ensuring the performance of the electrical cabinet and battery modules. In addition, the technical solution of this application also has high flexibility and scalability, and the temperature threshold, critical value, and safety margin can be adjusted and optimized according to different application scenarios and actual needs.

[0079] In some embodiments, optionally, such as Figure 1 As shown, the cooling circulation loop 110 includes a first reversing valve 128, a first regulating valve 130, and a heating element 132. The first reversing valve 128 includes a first port 134, a second port 136, and a third port 138. The first port 134 is connected to one end of the evaporator 122, the second port 136 is connected to one end of the first regulating valve 130, and the third port 138 is connected to one end of the heating element 132. The pipe between the second port 136 and the other end of the evaporator 122 is a first flow path 140. The first regulating valve 130 and the second heat exchange assembly 126 are connected in series in the first flow path 140. The third port 138 is connected to the other end of the evaporator 122. The intermediate pipeline is the second flow path 142, and the heating element 132 is connected in series in the second flow path 142. The first flow path 140 and the second flow path 142 are connected in parallel. When the temperature control component 100 of the energy storage electrical cabinet satisfies Ta>T2-2 or Tu>T1-2, the first port 134, the second port 136 and the third port 138 of the first reversing valve 128 are opened, and the opening degree of the first regulating valve 130 is at the first opening degree. The first flow path 140 and the second flow path 142 are connected. When the temperature control component 100 of the energy storage electrical cabinet satisfies Ta>T2 or Tu>T1, the opening degree of the first regulating valve 130 is at the second opening degree, and the second opening degree is greater than the first opening degree.

[0080] Specifically, such as Figure 1 As shown, the cooling circulation loop 110 includes a first reversing valve 128, a first regulating valve 130, and a heating element 132. The first reversing valve 128 includes a first port 134, a second port 136, and a third port 138. The first port 134 is connected to one end of the evaporator 122, the second port 136 is connected to one end of the first regulating valve 130, and the third port 138 is connected to one end of the heating element 132. The pipe between the second port 136 and the other end of the evaporator 122 forms a first flow path 140. The first regulating valve 130 and the second heat exchange assembly 126 are connected in series in the first flow path 140. The pipe between the third port 138 and the other end of the evaporator 122 forms a second flow path 142. The heating element 132 is connected in series in the second flow path 142. The first flow path 140 and the second flow path 142 are arranged in parallel. By setting the first reversing valve 128 and the first regulating valve 130, the flow of the cooling medium (coolant) can be diverted and regulated, thereby achieving precise control over the heat dissipation effect in different areas within the electrical cabinet. This configuration not only improves heat dissipation efficiency but also makes the heat dissipation device more flexible and adaptable. It can provide targeted heat dissipation based on the heat generation and heat dissipation requirements of different components within the electrical cabinet of the energy storage unit 300, thus improving energy utilization efficiency and heat dissipation effect.

[0081] Specifically, the cooling circulation loop 110 includes a first flow path 140 and a second flow path 142, which are connected in parallel. The first flow path 140 contains a first regulating valve 130 and a second heat exchange component 126 connected in series, while the second flow path 142 contains a heating element 132 connected in series. The first and second flow paths 140, after being connected in parallel, are then connected in series with a first reversing valve 128 and an evaporator 122 to form the entire cooling circulation loop 110. The first reversing valve 128 has multiple ports, allowing it to selectively connect the first flow path 140 and the second flow path 142 through different ports, achieving flow diversion and flow regulation. In specific applications, the first reversing valve 128 is specifically a three-way reversing valve, and the energy storage battery component 320 is specifically a UPS backup battery.

[0082] Specifically, when the ambient temperature Ta inside the energy storage electrical cabinet 200 exceeds the first critical value T2 of the ambient temperature minus a preset offset (e.g., 2°C), or when the body temperature Tu of the external energy storage battery assembly 320 of the energy storage electrical cabinet 200 exceeds the first threshold T1 minus a preset offset (e.g., 2°C), all three ports of the first reversing valve 128 are opened, and the opening of the first regulating valve 130 is adjusted to a smaller first opening, allowing the cooling medium to flow through the second heat exchange assembly 126 and the heating element 132. At this time, because the opening of the first regulating valve 130 is small, the flow rate of the cooling medium entering the second heat exchange assembly 126 is relatively small, which can achieve preliminary heat dissipation of a part of the area inside the electrical cabinet of the energy storage unit 300. When the temperature Ta inside the energy storage electrical cabinet 200 exceeds the first critical value T2 of the ambient temperature, or when the body temperature Tu of the external energy storage battery assembly 320 exceeds the first threshold T1, the opening of the first regulating valve 130 is adjusted to a larger second opening, increasing the flow rate of the cooling medium entering the second heat exchange assembly 126 to improve heat dissipation. Simultaneously, since the heating element 132 is also connected in series in the second flow path 142, the cooling medium can absorb the heat generated by the heating element 132 as it flows through it, further improving heat dissipation efficiency. This configuration can automatically adjust the distribution and flow rate of the cooling medium according to the real-time temperature inside the electrical cabinet, achieving precise temperature control within the cabinet. In specific applications, the first opening of the first regulating valve 130 is 50%, and the second opening is 100%.

[0083] In some embodiments, optionally, such as Figure 1As shown, the refrigeration cycle loop 120 includes a second reversing valve 144, a second regulating valve 146, a condenser 148, and a compressor 150. The second reversing valve 144 includes a fourth port 152, a fifth port 154, and a sixth port 156. The fourth port 152 is connected to one end of the condenser 148, the fifth port 154 is connected to one end of the second regulating valve 146, and the sixth port 156 is connected to one end of the evaporator 122. The pipe between the fifth port 154 and one end of the evaporator 122 is a third flow path 158. The second regulating valve 146 and the first heat exchange component 124 are connected in series in the third flow path 158. The pipe between the sixth port 156 and one end of the evaporator 122 is a fourth flow path 160. The third flow path 158 and the fourth flow path 160 are connected in parallel. The temperature control component 100 of the energy storage electrical cabinet satisfies Ta > T4-2 or Tu > T3-2. In the case of [condition], the cooling circulation loop 110 is started, and the first regulating valve 130 is at the second opening degree. At the same time, the refrigeration circulation loop 120 is started, and the second regulating valve 146 is at the third opening degree. When the energy storage electrical cabinet temperature control component 100 satisfies Ta > T4 or Tu > T3, the second regulating valve 146 is at the fourth opening degree, which is greater than the third opening degree. Among them, if the energy storage electrical cabinet temperature control component 100 is in the working state, the fourth port 152, the fifth port 154 and the sixth port 156 of the second reversing valve 144 are open, and the third flow path 158 and the fourth flow path 160 are connected. If the energy storage electrical cabinet temperature control component 100 is in the standby state, the fourth port 152 and the fifth port 154 of the second reversing valve 144 are connected, the sixth port 156 is closed, the third flow path 158 is connected, and the fourth flow path 160 is closed.

[0084] Specifically, such as Figure 1As shown, the refrigeration cycle loop 120 includes a second reversing valve 144, a second regulating valve 146, a condenser 148, and a compressor 150. The second reversing valve 144 includes a fourth port 152, a fifth port 154, and a sixth port 156. The fourth port 152 is connected to one end of the condenser 148, the fifth port 154 is connected to one end of the second regulating valve 146, and the sixth port 156 is connected to one end of the evaporator 122. The pipe between the fifth port 154 and one end of the evaporator 122 forms a third flow path 158. The second regulating valve 146 and the first heat exchange assembly 124 are connected in series in the third flow path 158. The pipe between the sixth port 156 and one end of the evaporator 122 forms a fourth flow path 160. The third flow path 158 and the fourth flow path 160 are connected in parallel. By setting the second reversing valve 144 and the second regulating valve 146, the refrigerant can be diverted and its flow rate adjusted, thereby achieving precise control of the heat dissipation effect in different areas within the electrical cabinet. This design not only improves heat dissipation efficiency but also makes the heat dissipation device more flexible and adaptable. It can provide targeted heat dissipation based on the heat generation and heat dissipation requirements of different components within the energy storage unit 300 electrical cabinet, thereby improving energy utilization efficiency and heat dissipation effect. The dual heat dissipation mode design of the cooling circulation loop 120 and the cooling circulation loop 110 enables precise temperature control within the energy storage electrical cabinet 200.

[0085] Specifically, the refrigeration cycle loop 120 includes a third flow path 158 and a fourth flow path 160, which are connected in parallel. The third flow path 158 contains a second regulating valve 146 and a first heat exchange assembly 124 connected in series. The fourth flow path 160 is a pipe. The parallel connection of the third and fourth flow paths 158 and 160 is then connected in series with a second reversing valve 144, a condenser 148, a compressor 150, and an evaporator 122 to form the entire refrigeration cycle loop 120. The second reversing valve 144 has multiple ports, allowing it to selectively connect the third flow path 158 and the fourth flow path 160 through different ports, thus achieving refrigerant diversion and flow regulation. In specific applications, the second reversing valve 144 is specifically a three-way reversing valve.

[0086] Specifically, the refrigeration cycle loop 120, through the coordinated action of components such as the second reversing valve 144, the second regulating valve 146, the condenser 148, and the compressor 150, can flexibly adjust the flow rate and direction of the refrigerant according to the temperature conditions inside the energy storage electrical cabinet 200, i.e., the values ​​of Ta and Tu. When the temperature inside the electrical cabinet is high, i.e., when the conditions Ta > T4-2 or Tu > T3-2 are met, the refrigeration cycle loop 120 is activated, and the opening degree of the second regulating valve 146 is set to the third opening degree to control the refrigerant flow rate entering the first heat exchange component 124, thereby achieving an initial reduction in the temperature inside the electrical cabinet. When the temperature further increases, meeting the conditions Ta > T4 or Tu > T3, the opening degree of the second regulating valve 146 is increased to the fourth opening degree to increase the refrigerant flow rate and improve the cooling effect.

[0087] Furthermore, this technical solution also considers the different operating states of the energy storage electrical cabinet 200, namely the impact of the operating state or standby state on the cooling cycle loop 120. When the energy storage electrical cabinet 200 is in the operating state, the fourth port 152, the fifth port 154, and the sixth port 156 of the second reversing valve 144 are all open, causing the third flow path 158 and the fourth flow path 160 to be simultaneously open, thus allowing cooling to be selectively performed through the third flow path 158 or the fourth flow path 160 as needed. When the energy storage electrical cabinet 200 is in the standby state, in order to reduce energy consumption and noise, the sixth port 156 of the second reversing valve 144 is closed, the fourth flow path 160 is disconnected, and cooling is performed only through the third flow path 158. In specific applications, the third opening degree of the second regulating valve 146 is 50%, and the fourth opening degree of the second regulating valve 146 is 100%.

[0088] Through this design, the technical solution of this application not only achieves precise temperature control within the energy storage electrical cabinet 200, but also improves the system's energy efficiency ratio and flexibility. Simultaneously, the synergistic effect of the second regulating valve 146 connected in series with the first heat exchange component 124, and the parallel-connected third flow path 158 and fourth flow path 160, further enhances the reliability and stability of the energy storage system. This application achieves precise and efficient temperature control within the energy storage electrical cabinet 200 through the design of the refrigeration cycle loop 120 and the cooling cycle loop 110, as well as the precise control of components such as the second reversing valve 144, the second regulating valve 146, the first reversing valve 128, and the first regulating valve 130.

[0089] In some embodiments, optionally, such as Figure 1As shown, the energy storage electrical cabinet temperature control component 100 also includes a heating module 170. The heating module 170 is connected to the first flow path 140 and is located between the first reversing valve 128 and the first regulating valve 130. When the energy storage electrical cabinet temperature control component 100 satisfies Tu < T5, the first port 134 and the second port 136 are opened, the first flow path 140 is connected, and the opening degree of the first regulating valve 130 is at the second opening degree. The heating module 170 is started, and the second heat exchange component 126 is in heating mode to heat up the energy storage electrical cabinet 200. Here, T5 is the low temperature threshold of the energy storage battery component 320.

[0090] Specifically, such as Figure 1 As shown, the energy storage electrical cabinet temperature control component 100 also includes a heating module 170. The heating module 170 is connected to the first flow path 140 and positioned between the first reversing valve 128 and the first regulating valve 130. When the energy storage electrical cabinet temperature control component 100 satisfies Tu < T5, the first port 134 and the second port 136 are opened, the first flow path 140 is connected, and the opening degree of the first regulating valve 130 is at the second opening degree. At this time, the heating module 170 is activated, and the second heat exchange component 126 is in heating mode to heat the energy storage electrical cabinet 200. By setting the heating module 170 in the first flow path 140, when the temperature of the energy storage battery component 320 is lower than the low-temperature threshold, that is, when the temperature of the energy storage battery component 320 is lower than the normal preset operating temperature, the heating mode of the energy storage electrical cabinet temperature control component 100 is activated to ensure the normal operating temperature of the energy storage battery component 320. The temperature control component 100 of the energy storage electrical cabinet achieves precise control of the temperature inside the energy storage electrical cabinet 200 by flexibly adjusting the working status of the cooling circulation loop 110 and the heating module 170.

[0091] Specifically, when the temperature control component 100 of the energy storage electrical cabinet detects that the ambient temperature Ta of the energy storage electrical cabinet 200 is higher than a first critical value T2-2 of the ambient temperature of the energy storage electrical cabinet 200, or when the body temperature Tu of the external energy storage battery component 320 of the energy storage electrical cabinet 200 is higher than a first threshold value T1-2 of the temperature of the energy storage battery component 320, the first port 134, the second port 136, and the third port 138 of the first reversing valve 128 are all opened, allowing the coolant to circulate through the first flow path 140 and the second flow path 142, respectively. At this time, the opening degree of the first regulating valve 130 can be adjusted as needed to control the amount of coolant entering the second heat exchange component 126, thereby achieving the regulation of the temperature inside the electrical cabinet.

[0092] When the body temperature Tu of the external energy storage battery assembly 320 of the energy storage electrical cabinet 200 is lower than the low temperature threshold T5, it indicates that the temperature inside the electrical cabinet is too low and heating is required. At this time, the first port 134 and the second port 136 of the first reversing valve 128 are opened, the first flow path 140 is connected, and the opening degree of the first regulating valve 130 is at the second opening degree, i.e., 100%. At the same time, the heating module 170 is activated. When the coolant passes through the first flow path 140, it is heated by the heating module 170, and then the heat is transferred to the air inside the electrical cabinet through the second heat exchange component 126, thereby realizing the heating mode. Since the heating module 170 is located between the first reversing valve 128 and the first regulating valve 130, it can be ensured that the coolant can pass through the heating module 170 and be fully heated in the heating mode.

[0093] This not only improves the flexibility and adaptability of the temperature control component 100 in the energy storage electrical cabinet, but also ensures precise temperature control within the cabinet under various operating conditions, thereby guaranteeing the normal operation of the electrical components and extending their service life. Furthermore, by rationally setting the temperature threshold and regulating valve opening, energy consumption and temperature control performance can be further optimized.

[0094] In some embodiments, optionally, such as Figure 1 As shown, when the temperature control component 100 of the energy storage electrical cabinet satisfies Tb > Td, the fourth port 152 and the fifth port 154 are opened, the third flow path 158 is connected, and the opening degree of the second regulating valve 146 is at the second opening degree. The first heat exchange component 124 is in dehumidification mode to dehumidify the energy storage electrical cabinet 200. Here, Tb is the ambient humidity of the energy storage electrical cabinet 200, and Td is the dew point humidity.

[0095] Specifically, such as Figure 1 As shown, when the temperature control component 100 of the energy storage electrical cabinet satisfies Tb > Td, the fourth port 152 and the fifth port 154 are open, the third flow path 158 is connected, and the opening degree of the second regulating valve 146 is at the second opening degree. The first heat exchange component 124 is in dehumidification mode to dehumidify the energy storage electrical cabinet 200. By controlling the opening of the fourth port 152 and the fifth port 154 of the second reversing valve 144 and the opening degree of the second regulating valve 146, the flow rate of refrigerant entering the first heat exchange component 124 can be adjusted, thereby controlling the dehumidification effect of the first heat exchange component 124. When the ambient humidity Tb inside the energy storage electrical cabinet 200 is higher than the dew point humidity Td, it indicates that the air humidity inside the electrical cabinet is high, and the dehumidification mode needs to be activated. At this time, by adjusting the second reversing valve 144 and the second regulating valve 146, the refrigerant flows through the first heat exchange component 124, and the cooling effect of the first heat exchange component 124 condenses the moisture in the air into water droplets and discharges them, thereby achieving the purpose of dehumidification.

[0096] Specifically, in dehumidification mode, the fan speed can be further reduced to decrease the airflow, allowing the humid air to fully contact the first heat exchange component 124 and enhancing the dehumidification effect. Simultaneously, since the first heat exchange component 124 uses a U-shaped pipe with fins, the heat exchange area can be increased, improving dehumidification efficiency. Furthermore, based on the heating power and temperature sensitivity of different components within the energy storage electrical cabinet 200, the position and quantity of the fan, the first heat exchange component 124, and the second heat exchange component 126 can be flexibly set to meet the temperature and humidity control requirements of the energy storage electrical cabinet 200.

[0097] According to the second aspect of this application, such as Figure 2 , Figure 3 and Figure 4 As shown, an energy storage electrical cabinet 200 is also proposed, including: an energy storage electrical cabinet temperature control component 100 as described in any of the above embodiments; and a cabinet body 210, wherein a first heat exchange component 124 is disposed inside the cabinet body 210 and located at the bottom of the cabinet body 210, and a second heat exchange component 126 is disposed inside the cabinet body 210 and located above the first heat exchange component 124; a first sensor 220 is disposed inside the cabinet body 210 for detecting ambient temperature and ambient humidity; a second sensor 230 is disposed inside the cabinet body 210 for detecting the temperature of the energy storage battery component 320; and a fan component 240 is disposed inside the cabinet body 210 and located on the side close to the second heat exchange component 126 for supplying air to the first heat exchange component 124 and the second heat exchange component 126.

[0098] The energy storage electrical cabinet 200 provided in this application has all the beneficial effects of the energy storage electrical cabinet temperature control component 100, which are included in any of the above-mentioned technical solutions, and will not be described in detail here.

[0099] In addition, the energy storage electrical cabinet 200 also includes a cabinet body 210, a first sensor 220, a second sensor 230, and a fan assembly 240. The first heat exchange assembly 124 is located inside the cabinet body 210 at its bottom, and the second heat exchange assembly 126 is located inside the cabinet body 210 above the first heat exchange assembly 124. The first sensor 220 is located inside the cabinet body 210 and is used to detect ambient temperature and humidity. The second sensor 230 is located inside the cabinet body 210 and is used to detect the temperature of the energy storage battery assembly 320 in the energy storage container 300. The fan assembly 240 is located inside the cabinet body 210, near the second heat exchange assembly 126, and is used to supply air to both the first and second heat exchange assemblies 124 and 126.

[0100] Specifically, the energy storage electrical cabinet 200 is installed inside the energy storage container 300, which has strict requirements for ambient temperature and humidity. The cabinet body 210 is the main structure of the energy storage electrical cabinet 200, used to house and protect the internal temperature control components. The first heat exchange component 124 is connected to the refrigeration cycle loop 120 in the energy storage electrical cabinet temperature control component 100 via pipes, used to absorb heat from the bottom of the cabinet and remove it through refrigerant circulation. The first heat exchange component 124 uses a U-shaped pipe with fins to increase the heat exchange area and improve heat exchange efficiency. The second heat exchange component 126 is also connected to the cooling cycle loop 110 in the energy storage electrical cabinet temperature control component 100 via pipes, used to absorb heat from the upper middle part of the cabinet. Refrigerant can be introduced into the pipes of the first heat exchange component 124, and coolant can be introduced into the pipes of the second heat exchange component 126, adjusting the heat exchange efficiency according to the control strategy of the energy storage electrical cabinet temperature control component 100. The first sensor 220 is installed inside the cabinet 210 to detect ambient temperature and humidity in real time. Data from the first sensor 220 is input into the control system of the energy storage electrical cabinet temperature control component 100 for precise temperature and humidity control. The second sensor 230 is installed inside the cabinet 210 to detect the temperature of the energy storage battery module 320 in real time. Data from the second sensor 230 is also input into the control system of the energy storage electrical cabinet temperature control component 100 to ensure that the energy storage battery module 320 always operates within a suitable temperature range. The first sensor 220 can be specifically configured as a temperature and humidity sensor. The fan assembly 240 is installed inside the cabinet 210, located near the second heat exchange component 126. The fan assembly 240 supplies air to the first heat exchange component 124 and the second heat exchange component 126, accelerating airflow within the cabinet and improving heat exchange efficiency. The fan assembly 240's speed and start / stop can be flexibly adjusted according to the control strategy of the energy storage electrical cabinet temperature control component 100 to achieve precise temperature and humidity control. In specific applications, the fan assembly 240 can be specifically a fan, the first heat exchange assembly 124 can be specifically a first heat exchange plate, and the second heat exchange assembly 126 can be specifically a second heat exchange plate.

[0101] The specific working principle of the energy storage electrical cabinet 200 of this application is as follows: When the temperature or humidity inside the cabinet exceeds the preset value, the temperature control component controls the operation of the cooling circulation loop 110 and the refrigeration circulation loop 120 based on the data from the first sensor 220 and the second sensor 230. During the circulation process, the cooling circulation loop 110 and the refrigeration circulation loop 120 flow through the first heat exchange component 124 and the second heat exchange component 126 respectively, absorbing heat from inside the cabinet and removing moisture. At the same time, the fan component 240 starts and accelerates the airflow inside the cabinet, allowing hot air to pass through the heat exchange components for heat exchange more quickly. Through precise temperature and humidity control and flexible air supply methods, the energy storage electrical cabinet 200 can ensure that the electrical equipment inside the cabinet always operates under suitable environmental conditions, thereby improving the stability and service life of the equipment.

[0102] This application provides a temperature control component 100 for an energy storage electrical cabinet, namely a heat dissipation device for an energy storage electrical cabinet 200 and its application. The heat dissipation device can not only effectively control the temperature inside the cabinet, but also dehumidify the humid air inside the cabinet. Moreover, the heat dissipation device has low operating power, which can reduce the auxiliary power consumption of the overall system. At the same time, it has strong installation flexibility, adapts to the arrangement of electrical components inside the electrical cabinet, and can meet the temperature and humidity control requirements of the energy storage container 300.

[0103] The energy storage electrical cabinet temperature control component 100 provided in this application is a heat dissipation device for the electrical cabinet, integrating cooling, heating, and dehumidification functions. The flow rate of refrigerant in the pipelines is controlled by the control component, and the heat exchange efficiency within the energy storage electrical cabinet 200 is adjusted according to the heat output of the energy storage electrical cabinet 200. The cooling circulation loop 110 and the refrigeration circulation loop 120 control the flow direction of refrigerant and coolant through reversing three-way valves based on changes in the ambient temperature, improving control accuracy while reducing energy consumption. Simultaneously, based on the temperature and humidity data within the energy storage electrical cabinet 200, the speed and start / stop of the fan assembly 240 can be controlled to regulate the cooling and dehumidification effects of the first and second heat exchange plates. Furthermore, the positions of the fan assembly 240 and the first and second heat exchange plates can be flexibly set, placing temperature-sensitive components on the fan outlet surface and placing the first and second heat exchange plates around components with higher heat consumption, thus precisely controlling the ambient temperature around each component.

[0104] The technical effects of using the energy storage electrical cabinet 200 of this application are as follows: First, existing technologies use wall-mounted air conditioners to control the temperature and humidity inside the electrical cabinet. The energy storage electrical cabinet 200 of this application solves the problem of excessive auxiliary power consumption of the temperature control equipment in existing technologies, and is also more cost-effective. Second, the energy storage electrical cabinet 200 can be divided into heat exchange zones, allowing power devices of different power ratings to exchange heat in the same heat exchange zone, thus improving the heat exchange effect of targeted heat-sensitive devices. Third, the flexible setup and control methods are suitable for the highly customized market of the energy storage industry. The location and method of the heat dissipation device can be arranged according to the configuration of electrical devices and the model and location of high-power devices. Radiation and convection heat exchange are used to dissipate heat for high-power devices on the bus side, while forced air cooling is used to dissipate heat for heat-sensitive devices on the control side. Differentiation is made in the airflow path to achieve precise control.

[0105] In some embodiments, optionally, such as Figure 2 and Figure 3As shown, the energy storage electrical cabinet 200 also includes: a collector plate 250, which is disposed on the cabinet body 210 and located at the bottom of the first heat exchange component 124, for receiving condensate dripping from the first heat exchange component 124; and a drain pipe 260, which is disposed at the bottom of the cabinet body 210, for draining the condensate collected on the collector plate 250 from the cabinet body 210.

[0106] Specifically, the energy storage electrical cabinet 200 also includes a collector plate 250 and a drain pipe 260. The collector plate 250 is located inside the cabinet 210 at the bottom of the first heat exchange component 124, and is used to collect condensate dripping from the first heat exchange component 124. The drain pipe 260 is located at the bottom of the cabinet 210 and is used to drain the condensate collected on the collector plate 250 from the cabinet 210. By adding the collector plate 250 and the drain pipe 260, the energy storage electrical cabinet 200 further optimizes the drainage system inside the cabinet, ensuring a dry and clean environment inside the cabinet.

[0107] Specifically, the manifold 250 is located at the bottom of the first heat exchange assembly 124. When the first heat exchange assembly 124 operates in dehumidification mode, moisture in the air is condensed into water droplets and drips onto the manifold 250. The design of the manifold 250 not only effectively collects condensate but also prevents condensate from flowing inside the cabinet 210, avoiding potential electrical safety hazards.

[0108] Meanwhile, a drain pipe 260 is installed at the bottom of the cabinet 210 and connected to the manifold 250. The function of the drain pipe 260 is to promptly drain the condensate collected on the manifold 250 from the cabinet 210, thereby maintaining a dry environment inside the cabinet. This not only improves the moisture-proof performance of the energy storage electrical cabinet 200 but also extends the service life of the electrical components inside the cabinet.

[0109] In addition, the drain pipe 260 can be specifically configured as a drain hole, which is located at the bottom of the cabinet 210. The condensate collected on the manifold 250 is discharged from the cabinet 210 in a timely manner through the drain hole.

[0110] Specifically, such as Figure 2 and Figure 3As shown, during operation, hot air inside the energy storage electrical cabinet 200 sequentially passes through the first heat exchange component 124 and the second heat exchange component 126. After heat exchange with the coolant and refrigerant, it becomes cold air and is blown out by the fan assembly 240. The first heat exchange component 124 and the second heat exchange component 126 adopt a U-shaped pipe with fins, which can increase the heat exchange area and allow the hot air to exchange heat effectively with the heat exchange plates. In addition, the first heat exchange component 124 and the second heat exchange component 126 radiate heat with nearby heat-generating devices. Devices with high heat generation are placed near the first heat exchange component 124 and the second heat exchange component 126, while temperature-sensitive devices are placed near the fan assembly 240. This classification of heat-generating devices within the electrical cabinet allows for precise and reasonable control.

[0111] Specifically, the second heat exchange component 126 is filled with coolant, and the first heat exchange component 124 is filled with refrigerant. Since the first heat exchange component 124 filled with refrigerant needs to use metal pipes and has strong dehumidification capacity, the first heat exchange component 124 is placed below the second heat exchange component 126.

[0112] Furthermore, by using the fan assembly 240 to blow air, a negative pressure can be maintained inside the sheet metal shell of the energy storage electrical cabinet 200. Once the fan assembly 240 is turned on, the hot air inside the energy storage electrical cabinet 200 will exchange heat with the first heat exchange assembly 124 and the second heat exchange assembly 126. In this way, the heat dissipated by the high-heat-generating device will directly enter the temperature control module due to the negative pressure, thus preventing the heat from the high-heat-generating device from affecting other low-heat-generating electrical devices.

[0113] Furthermore, such as Figure 4 As shown, the fan assembly 240, the first heat exchange assembly 124, and the second heat exchange assembly 126 can be arranged vertically or horizontally, depending on the heating power of different components in the energy storage electrical cabinet 200, allowing for flexible and variable structural arrangements. Specifically, the manifold 250 can be configured as an inclined plate to ensure that condensate flows into the manifold cavity and ultimately exits through the drain hole.

[0114] According to the third aspect of this application, such as Figure 5 As shown, an energy storage container 300 is also proposed, including: an energy storage electrical cabinet 200 as described in the above embodiment; and a housing 310, wherein the energy storage electrical cabinet 200 is disposed on one side of the housing 310; and an energy storage battery assembly 320, wherein the energy storage battery assembly 320 is disposed on the other side of the housing 310 and is disposed opposite to the first heat exchange assembly 124, for providing power to the outside.

[0115] The energy storage container 300 provided in this application includes the energy storage electrical cabinet 200 of the above embodiment, and therefore has all the beneficial effects of the energy storage electrical cabinet 200, which will not be repeated here.

[0116] In addition, such as Figure 5 As shown, the energy storage container 300 also includes a housing 310 and an energy storage battery assembly 320. The energy storage electrical cabinet 200 is located on one side of the housing 310, and the energy storage battery assembly 320 is located on the other side of the housing 310 and is positioned opposite to the first heat exchange assembly 124. The energy storage battery assembly 320 is used to provide electrical energy to the outside world.

[0117] Specifically, according to the third aspect of this application, the proposed energy storage container 300 possesses precise temperature and humidity control and flexible air supply methods, ensuring stable operation of the electrical equipment within the enclosure 310 under suitable environmental conditions. The enclosure 310 is the main structure of the energy storage container 300, used to house and protect the internal energy storage electrical cabinet 200 and energy storage battery assembly 320. The design of the enclosure 310 should meet the requirements of ease of transportation, installation, and use, while also possessing good sealing and protection levels to ensure the safe operation of the internal equipment. The energy storage battery assembly 320 is located on the other side of the enclosure 310, opposite to the first heat exchange assembly 124 in the energy storage electrical cabinet 200. The energy storage battery assembly 320 is the core component of the energy storage container 300, used to store electrical energy and provide power to the outside world when needed.

[0118] Specifically, when the energy storage container 300 is in use, the energy storage battery module 320 begins to store electrical energy. Simultaneously, the temperature control component 100 inside the energy storage electrical cabinet 200 activates, ensuring a suitable environment for the operation of the electrical equipment. When power needs to be supplied to the outside, the energy storage battery module 320 converts the stored electrical energy into AC or DC power output that meets the requirements through devices such as inverters. Because the energy storage electrical cabinet 200 and the energy storage battery module 320 are positioned opposite each other, and the energy storage electrical cabinet 200 has precise temperature and humidity control and flexible air supply methods, it can ensure that the energy storage battery module 320 operates in an optimal working environment, thereby improving its energy storage efficiency and service life.

[0119] According to the fourth aspect of this application, such as Figure 6As shown, a control method for an energy storage electrical cabinet is also proposed to control the temperature control component of the energy storage electrical cabinet as described in the above embodiment. The control method includes: detecting the ambient temperature and humidity inside the energy storage electrical cabinet; in cooling mode, when the temperature control component of the energy storage electrical cabinet satisfies Ta > T2-2 or Tu > T1-2, starting the cooling circulation loop and opening the first port, second port, and third port of the first reversing valve, adjusting the opening degree of the first regulating valve to the first opening degree, and controlling the first flow path and the second flow path to be connected; when the temperature control component of the energy storage electrical cabinet satisfies Ta > T2 or Tu > T1, adjusting the opening degree of the first regulating valve to the second opening degree; when the temperature control component of the energy storage electrical cabinet satisfies Ta > T4-2 or Tu > T3-2, starting the cooling circulation loop. The first regulating valve is adjusted to the second opening degree, and the refrigeration cycle loop is started. The second regulating valve is adjusted to the third opening degree. When the temperature control component of the energy storage electrical cabinet meets the conditions of Ta > T4 or Tu > T3, the opening degree of the second regulating valve is adjusted to the fourth opening degree. If the temperature control component of the energy storage electrical cabinet is in the working state, the fourth, fifth, and sixth ports of the second reversing valve are opened simultaneously to control the third and fourth flow paths to be connected. If the temperature control component of the energy storage electrical cabinet is in the standby state, the fourth and fifth ports of the second reversing valve are opened, and the sixth port of the second reversing valve is closed to control the third flow path to be connected and the fourth flow path to be closed.

[0120] Specifically, the control method of the energy storage electrical cabinet achieves precise control of the ambient temperature and humidity inside the energy storage electrical cabinet by adjusting the working state of the cooling circulation loop and the refrigeration circulation loop, as well as the connection mode between the first reversing valve and the second reversing valve, and the opening degree of the first regulating valve and the second regulating valve.

[0121] like Figure 6 As shown in the figure, this application provides a control method for an energy storage electrical cabinet, which may include the following steps:

[0122] S502. Detect the ambient temperature and humidity inside the energy storage electrical cabinet;

[0123] S504. When the temperature control component of the energy storage electrical cabinet meets the conditions of Ta > T2-2 or Tu > T1-2, start the cooling circulation loop and open the first port, second port and third port of the first reversing valve, adjust the opening degree of the first regulating valve to the first opening degree, and control the first flow path and the second flow path to be connected.

[0124] S506. When the temperature control component of the energy storage electrical cabinet satisfies Ta>T2 or Tu>T1, adjust the opening of the first regulating valve to the second opening.

[0125] S508. When the temperature control component of the energy storage electrical cabinet meets the conditions of Ta > T4-2 or Tu > T3-2, start the cooling cycle circuit and adjust the first regulating valve to the second opening degree. At the same time, start the refrigeration cycle circuit and adjust the opening degree of the second regulating valve to the third opening degree.

[0126] S510. When the temperature control component of the energy storage electrical cabinet meets the conditions of Ta>T4 or Tu>T3, adjust the opening degree of the second regulating valve to the fourth opening degree.

[0127] S512, when the temperature control component of the energy storage electrical cabinet is in working condition, the fourth, fifth and sixth ports of the second reversing valve are opened simultaneously to control the conduction of the third and fourth flow paths.

[0128] like Figure 7 As shown in the figure, this application provides a control method for an energy storage electrical cabinet, which may further include the following steps:

[0129] S602. Detect the ambient temperature and humidity inside the energy storage electrical cabinet;

[0130] S604. When the temperature control component of the energy storage electrical cabinet meets the conditions of Ta > T2-2 or Tu > T1-2, start the cooling circulation loop and open the first port, second port and third port of the first reversing valve, adjust the opening degree of the first regulating valve to the first opening degree, and control the first flow path and the second flow path to be connected.

[0131] S606. When the temperature control component of the energy storage electrical cabinet satisfies Ta>T2 or Tu>T1, adjust the opening of the first regulating valve to the second opening.

[0132] S608. When the temperature control component of the energy storage electrical cabinet meets the conditions of Ta > T4-2 or Tu > T3-2, start the cooling circulation loop and adjust the first regulating valve to the second opening degree. At the same time, start the refrigeration circulation loop and adjust the opening degree of the second regulating valve to the third opening degree.

[0133] S610. When the temperature control component of the energy storage electrical cabinet meets the conditions of Ta > T4 or Tu > T3, adjust the opening degree of the second regulating valve to the fourth opening degree.

[0134] S612. When the temperature control component of the energy storage electrical cabinet is in standby mode, the fourth and fifth ports of the second reversing valve are opened, the sixth port of the second reversing valve is closed, and the third flow path is controlled to be open and the fourth flow path is closed.

[0135] Specifically, when the ambient temperature Ta is greater than the difference between T2 and 2, or when the temperature of the energy storage battery module Tu is greater than the difference between T1 and 2, the cooling circulation loop is activated. When the ambient temperature Ta is greater than T2, or when the temperature of the energy storage battery module Tu is greater than T1, the operating state of the cooling circulation loop is adjusted. When activating the cooling circulation loop, the first, second, and third ports of the first reversing valve are opened simultaneously. The opening degree of the first regulating valve is adjusted, initially set to the first opening degree to ensure sufficient cooling effect; subsequently, it is adjusted to the second opening degree according to changes in ambient temperature or humidity.

[0136] Specifically, when the ambient temperature Ta is greater than the difference between T4 and 2, or when the temperature of the energy storage battery module Tu is greater than the difference between T3 and 2, both the cooling cycle and the refrigeration cycle are activated. When the ambient temperature Ta is greater than T4, or when the temperature of the energy storage battery module Tu is greater than T3, the operating state of the refrigeration cycle is adjusted. When the refrigeration cycle is activated, the opening of the second regulating valve is adjusted to the third opening; subsequently, based on changes in ambient temperature or humidity, it is adjusted to the fourth opening.

[0137] Specifically, when the temperature control component of the energy storage electrical cabinet is in operation, the fourth, fifth, and sixth ports of the second reversing valve are opened simultaneously to control the conduction of the third and fourth flow paths.

[0138] When the temperature control component of the energy storage electrical cabinet is in standby mode, the sixth port of the second reversing valve is closed, and only the fourth and fifth ports are opened, controlling the third flow path to be open and the fourth flow path to be closed.

[0139] This application detects the ambient temperature Ta and the body temperature Tu of the energy storage battery modules inside the energy storage electrical cabinet. The detected temperature and humidity values ​​are compared with preset temperature and humidity thresholds. Based on the comparison results, it determines whether to activate the cooling and refrigeration circulation loops and adjust the opening of relevant valves. The opening and closing of the reversing valves are controlled according to the operating status of the temperature control components of the energy storage electrical cabinet. Real-time monitoring of temperature and humidity changes within the cabinet is performed, and the control strategy is adjusted as needed. Through precise temperature and humidity detection and threshold judgment, accurate control of the environment inside the energy storage electrical cabinet is achieved. The operating status of the cooling and refrigeration circulation loops and the valve openings are flexibly adjusted according to actual needs, improving the energy efficiency ratio. Through reasonable control strategies and valve control, stable operation of the energy storage electrical cabinet under various operating conditions is ensured. Therefore, through precise temperature and humidity detection and adjustment strategies, accurate control of the environment inside the energy storage electrical cabinet is achieved, improving the energy efficiency ratio and operational stability and reliability.

[0140] In some embodiments, the control method may optionally further include: in the heating mode, when the temperature control component of the energy storage electrical cabinet satisfies Tu < T5, opening the first port and the second port of the cooling circulation loop, controlling the first flow path to be connected, adjusting the opening degree of the first regulating valve to the second opening degree, and controlling the heating module to start.

[0141] Specifically, in heating mode, when the temperature control component of the energy storage electrical cabinet detects that the body temperature Tu of the energy storage battery module is lower than the low-temperature threshold T5 of the energy storage battery module, the first and second ports of the cooling circulation loop are opened, making the first flow path conductive. This ensures that the air inside the cabinet can be properly circulated during the heating process to improve heating efficiency. The opening degree of the first regulating valve is adjusted to the second opening degree. The flow rate of the cooling medium in the cooling circulation loop is controlled, thereby regulating the temperature inside the cabinet. The heating module is activated to provide heat to raise the temperature inside the cabinet. When the body temperature Tu of the energy storage battery module is lower than T5, activating the heating module can quickly raise the temperature inside the cabinet, and the evaporation of moisture in the air through heating also helps to reduce humidity.

[0142] like Figure 8 As shown in the figure, this application provides a control method for an energy storage electrical cabinet, which may further include the following steps:

[0143] S702, Detect the body temperature Tu of the energy storage battery module and the low temperature threshold T5 of the energy storage battery module;

[0144] S704. When the temperature control component of the energy storage electrical cabinet meets the condition that Tu < T5, the first port and the second port of the cooling circulation loop are opened, the first flow path is controlled to be connected, the opening degree of the first regulating valve is adjusted to the second opening degree, and the heating module is controlled to start.

[0145] By precisely controlling the operating status of the heating module and cooling circulation loop, as well as adjusting the valve opening, the system can flexibly respond to various temperature and humidity changes, ensuring the stable operation of the energy storage electrical cabinet. In heating mode, by rationally controlling the output power of the heating module and the flow rate of the coolant in the cooling circulation loop, highly efficient and energy-saving operation can be achieved.

[0146] In some embodiments, the control method may optionally further include: in dehumidification mode, when the temperature control component of the energy storage electrical cabinet satisfies Tb>Td, opening the fourth and fifth ports of the refrigeration cycle loop, controlling the third flow path to be connected, adjusting the opening degree of the second regulating valve to the second opening degree, and controlling the wind speed of the fan component to be reduced to the preset wind speed.

[0147] Specifically, in dehumidification mode, the energy storage electrical cabinet is ensured to effectively dehumidify when the humidity is too high, while maintaining an appropriate temperature.

[0148] Specifically, in dehumidification mode, when the temperature control component of the energy storage electrical cabinet detects that the ambient humidity Tb of the energy storage electrical cabinet is higher than the preset dehumidification temperature threshold Td (i.e., dew point humidity), the fourth and fifth ports of the refrigeration cycle loop are opened, making the third flow path conductive. Utilizing the cooling effect of the refrigeration cycle loop, the temperature and humidity inside the cabinet are reduced. By activating the third flow path, the refrigerant can flow in the refrigeration cycle loop, absorbing heat from inside the cabinet, thereby reducing the temperature. Adjusting the opening of the second regulating valve to the second opening degree controls the refrigerant flow rate in the refrigeration cycle loop, thus regulating the cooling effect inside the cabinet. In dehumidification mode, an appropriate refrigerant flow rate can more effectively reduce temperature and humidity. Simultaneously, the fan speed is controlled to decrease to a preset speed. During dehumidification, reducing the fan speed reduces the airflow speed inside the cabinet, thereby prolonging the heat exchange time between the refrigerant and the air inside the cabinet, improving the dehumidification effect. Reducing the fan speed also reduces energy consumption and noise. In specific applications, the preset fan speed is 50% of the normal fan speed.

[0149] like Figure 9 As shown in the figure, this application provides a control method for an energy storage electrical cabinet, which may further include the following steps:

[0150] S802. Detect the ambient humidity Tb and dew point humidity Td of the energy storage electrical cabinet;

[0151] S804. When the temperature control component of the energy storage electrical cabinet meets the condition that Tb>Td, open the fourth and fifth ports of the refrigeration cycle loop, control the third flow path to be connected, adjust the opening degree of the second regulating valve to the second opening degree, and control the wind speed of the fan component to be reduced to the preset wind speed.

[0152] By precisely controlling the operating status of the refrigeration cycle loop and the opening of the regulating valve, as well as reducing the airflow speed of the fan components, the system can achieve efficient dehumidification, ensuring that the humidity inside the cabinet remains within the set range. Through sophisticated control logic and real-time temperature and humidity monitoring, the energy storage electrical cabinet can be ensured to operate stably in dehumidification mode, extending the service life of the equipment.

[0153] Specifically, such as Figure 6 and Figure 7 As shown, in cooling mode: when Ta > T2-2 or Tu > T1-2, the opening of the first reversing valve is controlled to divert the coolant. Part of the coolant flows through the first flow path to the second heat exchange component, and the other part flows through the second flow path to other heat-generating components. The first regulating valve is adjusted to 50% opening to control the flow rate into the second heat exchange component. When Ta > T2 or Tu > T1, the first regulating valve is adjusted to 100% opening.

[0154] When Ta > T4-2 or Tu > T3-2, maintain the first reversing valve at its opening for flow diversion and the first regulating valve at 100% opening. Start the compressor. If the electrical cabinet is operating, open the second reversing valve to divert refrigerant; part of the refrigerant flows through the third flow path to the first heat exchange assembly, and part flows through the fourth flow path to the evaporator. If the electrical cabinet is in standby mode, open the second reversing valve to bypass the third flow path; the refrigerant from the condenser flows through the second reversing valve to the first heat exchange assembly. Adjust the second regulating valve to 50% opening. When Ta > T4 or Tu > T3, adjust the second regulating valve to 100% opening.

[0155] like Figure 8 As shown, heating mode: The only electrical component in the electrical cabinet that is sensitive to low temperature is the UPS. Assume that the low temperature threshold of the UPS is T5. When Tu < T5, the heating module is turned on and the valve bypass of the first reversing valve, i.e. the first flow path, is opened. The coolant passes through the heating module and then reaches the second heat exchange component. The first regulating valve is opened to 100%.

[0156] like Figure 9 As shown, in dehumidification mode: when the relative humidity Tb > Td collected by the temperature and humidity monitoring system, the compressor is turned on, the second reversing valve is bypassed, and the air flows through the third flow path. The second regulating valve is opened to 100% of its maximum opening, and the fan assembly speed is reduced to 50% of the normal airflow speed. This reduces the airflow speed, allowing the humid air to fully contact the first and second heat exchange components, enhancing the dehumidification effect. In practical applications, if the refrigeration cycle is a heat pump system, a heating module is not required. When the heating requirements inside the energy storage electrical cabinet are met, the compressor is turned on, using the reverse Carnot cycle principle to introduce heat from the outside into the electrical cabinet, thus meeting the heating requirements inside the energy storage electrical cabinet.

[0157] According to the fifth aspect of this application, such as Figure 10 As shown, a control device 400 for an energy storage electrical cabinet is also proposed.
