Those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific circumstances.

[0036] As described in the background, the energy storage container as an integrated energy storage system can realize efficient storage and release of energy and can be applied to various application scenarios, for example, in the field of renewable energy power generation such as wind energy and solar energy, it can be stored for subsequent use when there is excess power. In order to prolong the service life of the battery and improve the stability of the energy storage system, a special air conditioner is usually provided in the energy storage container to adjust the temperature in the container during the charging and discharging process of the battery in the energy storage system.

[0037] To meet the installation requirements of energy storage container and other application scenarios, air conditioners gradually develop towards miniaturization and slimness. In the case of smaller and smaller volume requirements for energy storage air conditioners, the installation process requirements for the internal structure of the air conditioner are also higher in order to ensure the normal operation of the air conditioner, especially the welding process requirements for the pipeline.

[0038] To solve the problem of increased installation process difficulty of existing energy storage air conditioners due to limited space, the present application provides an energy storage air conditioner, comprising a compressor, a condenser, an electronic expansion valve, and an evaporator. The inlet pipeline of the condenser is in communication with the exhaust pipeline of the compressor. The inlet pipeline of the electronic expansion valve is in communication with the outlet pipeline of the condenser. The inlet pipeline of the evaporator is in communication with the outlet pipeline of the electronic expansion valve. The outlet pipeline of the evaporator is in communication with the suction pipeline of the compressor. The connecting pipeline between the compressor, the condenser, the electronic expansion valve, and the evaporator includes at least one pair of vertical pipe sections, and the free ends of the pair of vertical pipe sections are directly or indirectly connected by welding.

[0039] In the case of the above technical solution, when the welding point is arranged on the vertical pipeline, the operation plane during welding is a horizontal plane. In the welding process, regardless of the height of the welding point, the problem of hindering the welding process caused by the bottom shell can be avoided as much as possible, thereby reducing the installation process difficulty and ensuring the connection strength between the pipelines.

[0040] Reference will now be made to the drawings Figures 1 to 4 The energy storage air conditioner of the present application is described. Among them, Figure 1 is the overall structure diagram of the first perspective of the energy storage air conditioner of the present application; Figure 2 is the overall structure diagram of the second perspective of the energy storage air conditioner of the present application; Figure 3 is the internal structure diagram of the energy storage air conditioner of the present application; Figure 4 is the welding point schematic diagram of the energy storage air conditioner of the present application.

[0041] As Figures 1 to 4 shown, in a preferred embodiment, the energy storage air conditioner comprises a shell 10, the inside of the shell 10 forms an accommodating cavity, and the accommodating cavity is provided with a compressor 20, a condenser 30, an electronic expansion valve 40, an evaporator 50, a fan 60, and an electric control box 70. Among them, as an example in the direction shown by Figure 1 , the shell 10 is set as an assembled shell, including a base and a top cover arranged opposite along the height direction, a front plate and a rear plate arranged opposite along the length direction, and a left side plate and a right side plate arranged opposite along the width direction. The compressor 20 is horizontally arranged on the base, and the front plate is provided with an air inlet 11, the rear plate is provided with a first air outlet 121, and the top cover is provided with a second air outlet 122.

[0042] The fan 60 is arranged on the air outlet side of the condenser 30, and the compressor 20, the electronic expansion valve 40, the evaporator 50 and the electric control box 70 are arranged on the air inlet side of the condenser 30. The exhaust pipeline 21 of the compressor 20 is communicated with the inlet pipeline 31 of the condenser 30 through the transition pipeline 80, and the end of the exhaust pipeline 21 of the compressor 20 and the front end of the transition pipeline 80 are vertically arranged and abutted with each other to form a first welding point 91, and the end of the transition pipeline 80 and the front end of the inlet pipeline 31 of the condenser 30 are vertically arranged and abutted with each other to form a second welding point 92. The inlet pipeline 41 of the electronic expansion valve 40 is communicated with the outlet pipeline 32 of the condenser 30, and the end of the outlet pipeline 32 of the condenser 30 and the front end of the inlet pipeline 41 of the electronic expansion valve 40 are vertically arranged and abutted with each other to form a third welding point 93.

[0043] The evaporator 50 comprises a first heat exchange pipeline and a second heat exchange pipeline, the inlet of the first heat exchange pipeline is communicated with the outlet of the electronic expansion valve 40, and the outlet of the first heat exchange pipeline is communicated with the suction port of the compressor 20. Specifically, the inlet pipeline 51 of the evaporator 50 is communicated with the outlet pipeline 42 of the electronic expansion valve 40, and the front end of the inlet pipeline 51 of the evaporator 50 and the end of the outlet pipeline 42 of the electronic expansion valve 40 are vertically arranged and abutted with each other. The outlet pipeline 52 of the evaporator 50 is communicated with the suction pipeline 22 of the compressor 20, and the end of the outlet pipeline 52 of the evaporator 50 and the front end of the suction pipeline 22 of the compressor 20 are vertically arranged and abutted with each other to form a fourth welding point 94.

[0044] In the present embodiment, during the operation of the energy storage air conditioner, the compressor 20 discharges high-temperature and high-pressure refrigerant gas, which first enters the condenser 30 to release heat, and then is throttled by the electronic expansion valve 40 to become low-temperature and low-pressure refrigerant liquid, which then enters the first heat exchange pipeline and the second heat exchange pipeline of the evaporator 50 to exchange heat with the heat exchange fluid such as water or ethylene glycol solution, and the low-temperature and low-pressure refrigerant liquid becomes low-temperature and low-pressure refrigerant gas after absorbing heat, and then returns to the compressor 20 to enter the next refrigeration cycle, and the heat exchange fluid after being cooled can enter the energy storage system to realize heat dissipation for the battery.

[0045] It needs to be explained that in the present embodiment, the energy storage air conditioner is arranged as a horizontal energy storage air conditioner, which can more effectively utilize the remaining space of the energy storage container compared with a vertical energy storage air conditioner. For example, the horizontal energy storage air conditioner can be directly arranged on the top of the energy storage container without requirements on the internal structure of the energy storage container. When assembling the energy storage air conditioner, the technician can arrange the components on the base of the shell 10 according to the sequence, and then realize the connection between the pipelines between the components by welding. Since the horizontal energy storage air conditioner has a lower height, when welding the connecting pipelines between the components, if the welding points are located on the horizontal pipelines, the operation plane of the technician is a vertical plane, and when welding to the bottom of the pipeline, the operation of the technician is affected by the base of the shell 10 or other components located at the bottom, thereby causing the welding process to be unable to be normally completed, affecting the connection strength between the pipelines, and when the welding points are located on the vertical pipelines, the operation plane of the technician is a horizontal plane, at this time, the installation sequence of the components can be used to reduce the influence of other components on the welding process, thereby reducing the installation process difficulty of the energy storage air conditioner and ensuring the connection strength between the pipelines.

[0046] It can be understood by those skilled in the art that in the present embodiment, arranging the welding points on the vertical pipelines only means that the welding points for welding operation inside the shell 10 are located on the vertical pipelines, and there is no requirement for the pipelines that can be welded outside. The welding points of this part can be located on the horizontal pipelines or the vertical pipelines. That is, the technician can first complete the welding operation required for the inlet pipeline and the outlet pipeline of the corresponding component outside, and then arrange the component inside the shell 10, and complete the welding operation of the connecting pipeline between the component and other components inside the shell 10. Therefore, the arrangement of the first welding point 91, the second welding point 92, the third welding point 93 and the fourth welding point 94 is not necessary, and those skilled in the art can change it according to the needs. In an alternative embodiment, when the welding between the suction pipeline 22 of the compressor 20 and the outlet pipeline 52 of the evaporator 50 can be completed outside, the end of the outlet pipeline 52 of the evaporator 50 and the front end of the suction pipeline 22 of the compressor 20 can be arranged horizontally, and the welding point between them is located on the horizontal pipeline. In another alternative embodiment, the electronic expansion valve 40 can be arranged above the end of the outlet pipeline 32 of the condenser 30 as a whole, the arrangement of the third welding point 93 can be omitted, and the end of the outlet pipeline 42 of the electronic expansion valve 40 is arranged vertically, so that the outlet pipeline 42 of the electronic expansion valve 40 and the front end of the inlet pipeline 51 of the evaporator 50 are connected to each other and form a welding point.

[0047] It is understood by those skilled in the art that, in the present embodiment, the end of the discharge pipeline 21 of the compressor 20 extends vertically upward, the front end between the inlet pipelines 31 of the condenser 30 extends vertically downward, thus, to complete the communication between the discharge pipeline 21 of the compressor 20 and the inlet pipeline 31 of the condenser 30, the extending directions of the front end and the end of the transition pipeline 80 are opposite, but the arrangement of the transition pipeline 80 is not fixed, in an alternative embodiment, if the end of the discharge pipeline 21 of the compressor 20 extends vertically upward, and the front end of the inlet pipeline 31 of the condenser 30 also extends vertically upward, then the communication between the two can be achieved by a U-shaped transition pipeline 80. In another alternative embodiment, if the two vertical pipeline sections can be directly connected, the transition pipeline 80 can also be omitted.

[0048] It is to be explained that the shell 10 is not necessarily provided, those skilled in the art can determine the forming mode of the shell 10 according to the needs, for example, the shell 10 except the top cover can be integrally formed, and the top cover is welded to the remaining shell 10 after the air conditioner is assembled, but considering the difficulty of the installation process, it is a better choice to provide the shell 10 as an assembled shell. In addition, although the present embodiment is introduced in combination with the horizontal energy storage air conditioner, this is not intended to limit the protection scope of the present application, those skilled in the art can apply the present application to other air conditioners such as vertical energy storage air conditioners without departing from the principles of the present application. At this time, the specific arrangement of each component is not fixed, those skilled in the art can change according to the needs, for example, changing the layout of each component inside the air conditioner, so that the evaporator 40 can be provided as an air-refrigerant heat exchanger.

[0049] Those skilled in the art will understand that the combination of features of different embodiments means that they are within the scope of the present application and form different embodiments, although some embodiments described herein include certain features but not others included in other embodiments. For example, in the claims of the present application, any one of the claimed embodiments can be used in any combination.

[0050] So far, the technical solution of the present application has been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after the changes or replacements will fall within the protection scope of the present application.
