The expansion tank 38 is connected with the PCS-end condenser 32 and the battery-end condenser 31 respectively and is used to receive and store the steam generated by the PCS-end condenser 32 and the battery-end condenser 31 during the cooling process. When the steam condenses in the expansion tank 38, the volume is reduced, thereby providing a buffer space for the system and helping to maintain the pressure stability of the system. In addition, the expansion tank 38 is also equipped with a pressure relief valve. When the internal pressure of the system exceeds the preset safety value, the valve is automatically opened to release the excess pressure, thereby ensuring the safe operation of the entire heat dissipation system. The battery-end condenser 31 and the PCS-end condenser 32 share the expansion tank 38, thereby reducing the number of expansion tanks 38, optimizing the setting of the pipeline and improving the compactness of the structure to a certain extent.

[0067] In some embodiments, a plurality of expansion tanks 38 are arranged. The volume of each expansion tank 38 can be reduced, so that the expansion tank 38 can be installed in a smaller space and the space utilization is improved. For example, three expansion tanks 38 can be arranged. In other embodiments, four expansion tanks 38 can be arranged.

[0068] The plurality of expansion tanks 38 are arranged in a row. The expansion tanks 38 are arranged at the same height of the frame 11, thereby optimizing the setting of the connecting pipeline and reducing the length of the pipeline. The compactness of the energy storage air conditioner structure is improved and the product cost is saved.

[0069] The back of the frame 11 is provided with a plurality of cross beams, and the expansion water tank 38 is connected to the cross beams at the upper part of the frame 11. The upper part and the lower part of the expansion water tank 38 are respectively connected to two cross beams arranged at intervals, so that the upper part and the lower part of the expansion water tank 38 can be stably connected to the frame 11.

[0070] As shown in some embodiments, Figure 4 The heat dissipation system 3 includes a compressor 39. The compressor 39 is arranged behind the PCS end condenser 32 and on the return air path of the fan assembly 33. The compressor 39 is arranged on the return air path of the fan assembly 33, so that the compressor 39 can be cooled by the return air of the fan, improving the heat dissipation effect. In addition, the compressor 39 is arranged behind the PCS end condenser 32, and the compressor 39 is connected to the battery end condenser 31 and the PCS end condenser 32 through the cooling medium circulation pipeline respectively. By reasonably arranging the cooling medium circulation pipeline, the cooling medium circulation pipeline can be completely arranged behind the PCS end condenser 32, which is convenient for the production and assembly of the whole machine. The compressor 39 can be arranged below the expansion water tank 38, effectively utilizing the space below the expansion water tank 38.

[0071] As shown in some embodiments, Figure 1 The top rear end of the shell 1 is provided with a fan return air inlet 13. The fan return air inlet 13 is arranged at the top rear end, so that the return air of the fan can pass through the compressor 39, the PCS end condenser 32 and the battery end condenser 31 before entering the fan assembly 33.

[0072] The top of the shell 1 is provided with a plurality of fan return air inlets 13, which can increase the return air volume of the fan and improve the heat dissipation effect.

[0073] As shown in some embodiments, Figure 1 and Figure 4 The left side and the right side of the shell 1 near the rear part can be provided with a return air inlet 13, which extends along the height direction of the battery end condenser 31 and corresponds to the rear of the PCS end condenser 32, so as to ensure that the fan has a large return air volume and the return air can pass through the compressor 39, the PCS end condenser 32 and the battery end condenser 31.

[0074] As shown in some embodiments, Figures 2 to 4As shown, the heat dissipation system 3 can include a water pump 313 and a heat exchanger 312. The water pump 313 and the heat exchanger 312 are respectively arranged at the lower part of the shell 1 and are respectively located at both sides of the shell 1 in the length direction. Since the water pump 313 and the heat exchanger 312 have large weights, arranging the water pump 313 and the heat exchanger 312 at the lower part of the shell 1 can lower the gravity center of the energy storage air conditioner and improve the stability of the whole machine. Arranging the water pump 313 and the heat exchanger 312 at both sides of the shell 1 in the length direction can not only improve the balance of the whole machine, but also provide a large space between the water pump 313 and the heat exchanger 312, which is convenient for the layout of the pipeline.

[0075] In some embodiments, the heat exchanger 312 is provided with bolt columns on opposite sides, and is fixed to the frame 11 through bolt shafts and structural members, which is stable in connection and convenient for disassembly and assembly. The bottom of the heat exchanger 312 is provided with a support member connected with the frame 11, which ensures the stable and reliable fixation of the heat exchanger 312.

[0076] In order to ensure the heat preservation effect of the heat exchanger 312, the outer surface of the heat exchanger 312 can be wrapped with a heat preservation material. The heat preservation material can be polyurethane foam, rock wool, glass wool or silicate, etc. These heat preservation materials have excellent heat insulation performance, can effectively reduce heat loss and improve the heat efficiency of the heat exchanger 312. At the same time, they also have good fireproof performance and corrosion resistance, which can ensure the long-term stable operation of the heat exchanger 312.

[0077] In some embodiments, the heat exchanger 312 can be a plate heat exchanger. The plate heat exchanger has high efficient heat transfer performance, and is composed of parallel arranged plate pieces, which has compact structure, small occupied area, is suitable for installation in limited space, and is easy to disassemble and clean, which is convenient for maintenance and can maintain the high efficient operation of the heat exchanger 312.

[0078] In some embodiments, as shown in Figures 2 to 4 The heat dissipation system 3 can include a liquid supplement tank 311 and a liquid supplement pump 310. The liquid supplement tank 311 and the liquid supplement pump 310 are arranged above the water pump 313, and the liquid supplement tank 311 is arranged above the liquid supplement pump 310, which is convenient for the layout of the pipeline. When the external temperature changes, the volume of the cooling medium in the heat dissipation system 3 will change due to thermal expansion and contraction. The arrangement of the liquid supplement tank 311 and the liquid supplement pump 310 can prevent the heat dissipation system 3 from being short of liquid or high pressure. The liquid supplement tank 311 is connected with the cooling medium circulation pipeline of the heat dissipation system 3. When the decrease of the cooling medium is detected, the liquid supplement pump 310 will automatically start to supplement the cooling medium in the liquid supplement tank 311 to the heat dissipation system 3, which ensures the normal operation of the system. In addition, the liquid supplement tank 311 can also play a buffering role to balance the pressure fluctuation of the cooling medium in the heat dissipation system 3, which further protects the stability and safety of the system.

[0079] In some embodiments, as shown in Figure 2As shown, the heat dissipation system 3 further comprises a heater 314. The heater 314 is arranged at the rear of the electric control box 21 and is connected to the circulating pipeline of the cooling medium. The heater 314 is arranged at the rear of the electric control box 21, so that the heater 314 is between the water pump 313 and the heat exchanger 312, facilitating the layout of the pipeline.

[0080] The heater 314 can heat the cooling medium when necessary to ensure stable operation of the system under various ambient temperatures. When the external temperature is too low, which may cause the temperature of the cooling medium to drop and affect the heat dissipation effect of the system, the heater 314 will start to heat the cooling medium to raise its temperature, thereby ensuring efficient heat dissipation of the system. In addition, the design of the heater 314 also fully considers the energy saving and environmental protection requirements, and only starts when necessary, avoiding unnecessary energy waste.

[0081] In summary, the battery end condenser and the PCS end condenser of the present application share the water pump, the heater, the heat exchanger, the fan assembly, the expansion tank and the liquid supplement tank, simplifying the structure of the unit. By arranging the battery end condenser, the PCS end condenser and the compressor in sequence at the rear of the fan assembly, and arranging the battery end condenser, the PCS end condenser and the compressor in the return air path of the fan assembly, the battery end condenser, the PCS end condenser and the compressor can all be cooled by the fan assembly, improving the heat dissipation effect of the energy storage air conditioner, and the cooling medium circulating pipeline can be arranged at the rear of the condenser, optimizing the layout of the cooling medium circulating pipeline. In addition, by arranging multiple expansion tanks in the same height, the volume of a single expansion tank is reduced, the installation space limitation on the expansion tank is reduced, and the pipeline layout is simplified, saving pipeline cost.

[0082] It can be understood that for those skilled in the art, equivalent replacements or changes can be made according to the technical solutions and the application concepts of the present application, and all these changes or replacements shall belong to the protection scope of the claims attached to the present application.
