[0002] The energy storage system involves important components such as battery cells, inverters, transformers, and air conditioners, but each component has a loss problem that affects the system efficiency. Some components have serious heating problems, so how to dissipate heat from the components efficiently and energy-savingly is a technical problem facing the industry.

[0003] In the energy storage system, electricity needs to be stored and released, which involves the mutual conversion of DC and AC, which involves the inverter. For the inverter, it generates a lot of heat, so the energy storage system needs to focus on the heat dissipation of the inverter. Energy storage is often combined with power stations, which are often located at the seaside. Therefore, for projects at the seaside, if the heat dissipation system is not designed properly, it will cause the inverter to explode or reduce the frequency, which will greatly limit the use of the entire energy storage system. The market basically leaves enough margin, does not make specific air duct design, and lacks condensation control mechanism, which can easily cause uneven temperature in the box, short circuit of air inlet and outlet, and condensation corrosion of components in the box.

[0050] The inverter 3, the air conditioner 2, the air supply device 4 and the air return device 5 are all installed in the box 1, the output air flow direction of the air supply device 4 is the air inlet of the inverter 3, and the air return device 5 is connected to the air outlet of the inverter 3;

[0051] It also includes a condensation detection device 8, an EMS controller (not shown in the figure) and two return air outlet adjustment devices 23, the condensation detection device 8 is installed on the inverter 3, and the two return air outlet adjustment devices 23 are respectively installed on the upper return air outlet 6 and the lower return air outlet 7 in an openable and closable manner, and the inverter 3, the air conditioner 2, the wind speed and temperature sensor 9, the condensation detection device 8 and the return air outlet adjustment device 23 are all connected to the EMS controller;

[0052] The EMS controller controls the power of the inverter 3 and the cooling capacity of the air conditioner 2 and controls the opening and closing states of the two return air outlet adjustment devices 23 according to the data sent by the wind speed and temperature sensor 9 and the condensation detection device 8 .

[0053] The above means that the EMS controller of the heat dissipation duct system of the inverter 3 of the present invention obtains the condensation gear data of the condensation detection device 8, and adjusts the power of the inverter 3 in real time according to the condensation gear data, thereby optimizing the heat dissipation efficiency of the inverter 3 and reducing condensation corrosion. The EMS controller obtains the data on wind speed and temperature through the wind speed temperature sensor 9, and adjusts the cooling capacity of the air conditioner 2 and the opening area of ​​the return air outlet adjustment device 23 on the corresponding upper return air outlet 6 or lower return air outlet 7 in real time, thereby adjusting the air inlet temperature of the air conditioner 2, and effectively avoiding the high air outlet temperature of the inverter 3 from burning the surrounding devices or burning the maintenance and commissioning personnel, creating a comfortable and safe environment and prolonging the life of the devices.

[0054] Specifically, the air inlet of the air conditioner 2 is connected to a return air device 5, and the other end of the return air device 5 is connected to the air outlet of the inverter 3. The return air device 5 can be a return air duct 50. The return air device 5 is provided with an upper return air port 6 and a lower return air port 7. The upper return air port 6 and the lower return air port 7 are both provided with an openable and closable return air port adjustment device 23, which is used to suck the lower temperature airflow outside the return air device 5 into the return air device 5. Specifically, the return air device 5 concentrates the air of the cabin 10 in the box body 1 and the hot air discharged by the inverter 3 for a certain mixing and then returns them to the air inlet of the air conditioner 2, so as to avoid the high temperature alarm caused by the excessive return air temperature of the air conditioner 2 and the frequent adjustment of the compressor of the air conditioner 2 to reduce the heat exchange efficiency.

[0055] It can be understood that in this embodiment, the box 1 may include multiple groups of air conditioners 2 and multiple groups of inverters 3, each air conditioner 2 is connected to an inverter 3 and an EMS controller, each air conditioner 2 is connected to an inverter 3 through a return air device 5 and an air supply device 4, each return air device 5 is provided with an upper return air outlet 6 and a lower return air outlet 7, and each return air device 5 is installed with multiple wind speed and temperature sensors 9, such as Figures 2 to 3 shown.

[0056] In this embodiment, one end of the air supply device 4 is connected to the air outlet of the air conditioner 2, and the other end of the air supply device 4 extends along the top wall of the box body 1 to the top of the inverter 3;

[0057] The return air device 5 is installed on the bottom surface of the box body 1 , one end of the return air device 5 is connected to the air inlet of the air conditioner 2 , and the other end of the return air device 5 is connected to the air outlet of the inverter 3 .

[0058] As mentioned above, the air supply device 4 can be an air supply duct, which effectively delivers the cold air from the air outlet of the air conditioner 2 to the top of the air inlet of the inverter 3. The inverter 3 then sucks the cold air into the unit through the centrifugal fan above itself to dissipate the heat of the internal heating components.

[0059] The return air device 5 guides the hot air from the outlet of the inverter 3 back to the air inlet of the air conditioner 2. The return air device 5 separates the hot air from the inverter 3 from the environment of the cabin 10 in the box body 1, ensuring a comfortable environment when the cabin 10 is inspected or some components are repaired. In addition, the setting of the return air device 5 also makes it difficult for the cold and hot air to short-circuit, the temperature of the return air is more accurate, the heat exchange efficiency of the air conditioner 2 unit is high, the heat dissipation effect of the inverter 3 unit is good, and the system is efficient and energy-saving.

[0060] The inverter 3 converts the system DC power into AC power and connects to the grid as a supplement to meet the user's power demand. The inverter 3 has air intake from the top and air outlet from the bottom. The air conditioner 2 in this embodiment is a full-frequency air conditioner 2, which is used to dissipate heat from the inverter 3 in the cabin 10; the air conditioner 2 supplies air from the top and returns air from the front below.

[0061] In this embodiment, if Figures 4 to 5 As shown, the return air outlet adjustment device 23 includes a stepper motor 12, a screw 13, a threaded slider 11 installed on the screw 13, a return air outlet cover 14, a track 16, and a slider 15 installed on the track 16. The two ends of the return air outlet cover 14 are respectively installed on the threaded slider 11 and the slider 15. The stepper motor 12 drives the threaded slider 11 to move along the screw 13.

[0062] As mentioned above, the stepper motor 12 has a signal line connected to the EMS controller. After the stepper motor 12 receives the instruction, it controls the stepper motor 12 to start the rotating screw 13 to move forward or backward, thereby pushing the threaded slider 11 and the return air outlet cover 14 to move, thereby realizing the control of the opening and closing degree of the upper return air outlet 6 or the lower return air outlet 7 from 0 to 100%.

[0063] In this embodiment, if Figures 6 to 7 As shown, the condensation detection device 8 includes a condensation detector 21 and a wireless digital camera 20. The condensation detector 21 includes a housing 19, a support 18 installed in the inner cavity of the housing 19, and a condensation detection board 22 installed on the support 18. The condensation detection board 22 is provided with a test paper 17 for detecting water vapor. The wireless digital camera 20 captures the real-time color of the test paper 17 and records the condensation gear data corresponding to the real-time color.

[0064] The above-mentioned, including the condensation detector 21, contains a test paper 17 that is particularly sensitive to water vapor. The surface of the test paper 17 is covered with a layer of special chemical substances. This substance is very sensitive to water vapor. When the humidity change is detected, it will cause a sensitive reaction, resulting in 5 different levels of color change. The higher the level, the more serious the condensation phenomenon; the wireless digital camera 20 is a quasi-condensation detection device, which can clearly detect the color change of the internal test paper 17. Before leaving the factory, take pictures of the different color levels of the test paper 17 and transmit them to the wireless digital camera 20 for grade corresponding memory. After starting operation, the wireless digital camera 20 has deep learning capabilities, can continuously memorize the different levels of color of the test paper 17, and record the condensation gear data corresponding to the real-time color, and send the condensation gear data to the EMS controller.

[0065] Therefore, the heat dissipation duct of the inverter 3 of this embodiment is designed as an internal circulation, which effectively avoids the influence of the harsh environment of high temperature and high humidity at the seaside, and prevents the entry of salt mist particles to cause corrosion damage; the condensation detection device 8 is designed to effectively prevent the inverter 3 and the air conditioner 2 from short-circuiting or being forced to shut down due to condensation during operation, and effectively prevents the inverter 3 or the air conditioner 2 from condensing and then corroding the components and causing damage, adapting to the high corrosion resistance design at the seaside to ensure the safe and stable operation of the equipment.

[0066] In this embodiment, there are two wind speed temperature sensors 9 , one wind speed temperature sensor 9 is installed between the air outlet of the inverter 3 and the lower return air outlet 7 , and the other wind speed temperature sensor 9 is installed between the lower return air outlet 7 and the upper return air outlet 6 .

[0067] The above means that one wind speed temperature sensor 9 is installed between the air outlet of the inverter 3 and the lower return air outlet 7 to record the hot air data of the air outlet of the inverter 3; the other wind speed temperature sensor 9 is installed between the lower return air outlet 7 and the upper return air outlet 6 to record the hot air data of the mixed wind of the inverter 3 and the air flow in the cabin. It can be understood that both wind speed temperature sensors 9 are installed in the inner cavity of the return air device 5.

[0068] In this embodiment, if Figure 8 , Fig. 9 As shown, the execution process of the EMS controller includes:

[0069] S1 obtains the supply air temperature T1 of the air conditioner 2, obtains the outlet air temperature T2 and the outlet air speed v of the wind speed temperature sensor 9 installed between the air outlet of the inverter 3 and the lower return air outlet 7, and obtains the mixed air temperature Th recorded by the wind speed temperature sensor 9 installed between the lower return air outlet 7 and the upper return air outlet 6;

[0070] S2 calculates the load working power W of the inverter 3 according to the supply air temperature T1, the outlet air temperature T2, the outlet air speed v and the mixed air temperature Th;

[0071] S3 controls the air conditioner 2 to increase the cooling capacity by a% according to the power W.

[0072] As mentioned above, the EMS controller is used to adjust the temperature environment of the cabin 10 and maintain the maximum cooling efficiency of the air conditioner 2 to minimize the power consumption efficiency. The EMS controller calculates the load working power W of the inverter 3. The EMS control can also directly obtain its power W through the connected inverter 3 and send instructions to the air conditioner 2 to adjust the cooling capacity. The air conditioner 2 appropriately amplifies the cooling capacity by a% according to this demand for adjustment, such as Fig. 9 As shown, the cooling capacity of air conditioner 2 is Q= (1+a%)W.

[0073] In this embodiment, the execution process of the EMS controller further includes:

[0074] Acquiring the condensation gear data;

[0075] When the condensation gear data is less than 2, the optimal return air temperature T of the air conditioner 2 is preset;

[0076] When the mixed air temperature Th is greater than the optimal return air temperature T+1 (if not, it is determined whether the mixed air temperature Th is less than the optimal return air temperature T-1), the EMS controller controls the corresponding return air outlet adjustment device 23 to increase the opening area of ​​the lower return air outlet 7, and at the same time controls the corresponding return air outlet adjustment device 23 to reduce the opening area of ​​the upper return air outlet 6, so that more cold air from the cabin 10 flows into the return air device 5 and is fully mixed with the hot air discharged from the inverter 3; when the mixed air temperature Th When the mixed air temperature Th is equal to the optimal return air temperature T-1, stop adjusting the opening areas of the lower return air outlet 7 and the upper return air outlet 6; it can be understood that in the process of increasing the opening area of ​​the lower return air outlet 7 and decreasing the opening area of ​​the upper return air outlet 6, that is, when the cold air from the cabin 10 flows into the return air device 5, the mixed air temperature Th will gradually decrease from greater than the optimal return air temperature T+1 to the mixed air temperature Th equal to the optimal return air temperature T-1, and stop adjusting the opening area when T-1 is reached, and return to step S1.

[0077] When the mixed air temperature Th is less than the optimal return air temperature T-1 (when it is judged that "the mixed air temperature Th is greater than the optimal return air temperature T+1" is no, continue to judge "whether the mixed air temperature Th is less than the optimal return air temperature T-1", if it is still no, return to step S1), the EMS controller controls the corresponding return air outlet adjustment device 23 to reduce the opening area of ​​the lower return air outlet 7, and at the same time controls the corresponding return air outlet adjustment device 23 to increase the opening area of ​​the upper return air outlet 6, so that less cold air from the cabin 10 flows into the return air device 5 and is fully mixed with the hot air discharged from the inverter 3; when the mixed air temperature Th is equal to the optimal return air temperature T+1, stop adjusting the opening areas of the lower return air outlet 7 and the upper return air outlet 6. It can be understood that in the process of reducing the opening area of ​​the lower return air outlet 7 and increasing the opening area of ​​the upper return air outlet 6, that is, when the cold air from the cabin 10 is reduced from flowing into the return air device 5, the mixed air temperature Th will gradually increase from being less than the optimal return air temperature T-1 to the mixed air temperature Th being equal to the optimal return air temperature T+1, and when T+1 is reached, the opening area adjustment is stopped and the process returns to step S1.

[0078] In this embodiment, the execution process of the EMS controller further includes:

[0079] Acquiring the condensation gear data;

[0080] When the condensation gear data is equal to 2, the EMS controller controls the air conditioner 2 to increase the cooling capacity by a% according to the power W;

[0081] When the condensation gear data is equal to 3, the EMS controller controls the power W to reduce b% to operate;

[0082] When the condensation gear data is equal to 4, the EMS controller controls the power W to reduce (b+c)% to operate;

[0083] When the condensation gear data is equal to 5, the EMS controller sends out an alarm signal and controls the power W to reduce by (b+c+d)%.

[0084] The above all refers to the EMS controller controlling the inverter 3 to reduce the load working power W, that is, when the condensation gear data is higher, the EMS controller controls the inverter 3 to reduce the load working power more. When the condensation gear data is equal to 2, return to step S3.

[0085] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0086] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
