[0043] 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, and 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, the energy storage container usually needs to be provided with a special energy storage air conditioner such as a door-mounted air conditioner to adjust the temperature in the container.

[0044] In order to meet the installation requirements of the energy storage container and other application scenarios, the energy storage air conditioner needs to be miniaturized and slimmed down, which limits the installation space of various components such as compressors and heat exchangers inside the energy storage air conditioner. Under the influence of the compact installation space, the indoor air duct may also be affected by the limited space, which affects the uniformity of the air field, so that the evaporator cannot be fully utilized and affects the heat exchange efficiency of the energy storage air conditioner, thereby reducing the energy efficiency of the air conditioner.

[0045] In order to solve the problem of low air field uniformity and low energy efficiency of the existing energy storage air conditioner due to limited installation space, the present application provides an energy storage air conditioner, which comprises an air conditioner shell; a middle partition plate, the middle partition plate is arranged in the air conditioner shell and is used to separate the inside of the air conditioner shell into an indoor side and an outdoor side along the thickness direction; an evaporator, the evaporator is located in the indoor side, and a first distance is provided between the surface of the evaporator and the air conditioner shell facing the indoor side; and an indoor fan, the indoor fan is located in the indoor side and above the evaporator.

[0046] In the case of adopting the above technical solution, the indoor air enters from the air conditioner shell corresponding to the evaporator and blows out from the air conditioner shell corresponding to the indoor fan. The air volume of the evaporator surface gradually increases from bottom to top. The first distance can reduce the influence of the air conditioner shell on the top and bottom of the evaporator, ensure the upper and lower ends of the evaporator as effective heat exchange areas, and also improve the air volume of the bottom of the evaporator, thereby improving the air field uniformity of the evaporator surface, ensuring the heat exchange efficiency of the evaporator, and improving the energy efficiency of the energy storage air conditioner.

[0047] The energy storage air conditioner of the present application will be described below with reference to FIGS. 1 to 4.

The bottom of the sealing plate 41 abuts with the upper end of the evaporator 40. The two sides of the sealing plate 41 are respectively connected with the side panels 13 on both sides. A plurality of connecting holes are arranged on the side of the sealing plate 41 close to the front cover plate 14. The sealing plate 41 is connected with the first cover body 141 and the second cover body 142 of the front cover plate 14 through the plurality of connecting holes. That is, the sealing plate 41 is used to seal the joint positions of the first cover body 141 and the second cover body 142.

Specifically, as shown in FIG. 4, the electric control box 81 is formed with a folded edge parallel to the front cover plate 14 outward on both sides in width, the connecting plate 82 is arranged as an L-shaped plate, and the two plate surfaces of the L-shaped plate are connected to the folded edge of the electric control box 81 on the side and the side panel 13 on the side respectively. The electric control box 81 is provided with a variable frequency drive part (not shown in the figure), the heat dissipation piece includes a heat dissipation plate 91 and a heat dissipation fin 92, the electric control box 81 is provided with an opening, the heat dissipation plate 91 is fixedly connected to the inside of the electric control box 81, the heat dissipation fin 92 extends out of the back of the electric control box 81 through the opening, and the length direction of the heat dissipation fin 92 is parallel to the indoor side air direction, and the variable frequency drive part is fixedly connected to the heat dissipation plate 91. In this embodiment, the pitch of the heat dissipation fin 92 is any value in 6mm-7mm, the width of the heat dissipation fin 92 is any value in 18mm-20mm, and the length of the heat dissipation fin 92 is less than the length of the heat dissipation plate 91. Preferably, the pitch of the heat dissipation fin 92 is set to 6.5mm, and the width of the heat dissipation fin 92 is set to 19mm.

[0052] In the embodiment, the frequency conversion driving part in the electric control box 81 of the energy storage air conditioner can generate more heat during operation, the heat is transferred to the heat dissipation fin 92 through the heat dissipation plate 91, the indoor air is first cooled by the evaporator 40, and then flows upwards through the heat dissipation fin 92 to achieve heat dissipation for the electric control box 81, thereby ensuring the normal operation of the energy storage air conditioner, and the electric control box 81 is located on the indoor side, that is, the electric control box 81 is at least partially located on the indoor side, for example, a person skilled in the art can only set the back of the electric control box 81 on the indoor side, at this time, the back of the electric control box 81 is exposed to the indoor side air duct. In addition, in the embodiment, the evaporator 40 is located between the middle partition plate 20 and the front cover plate 14, and the surface of the evaporator 40 away from the middle partition plate 20 has a first spacing with the front cover plate 14, the first spacing is any value in 20-30 mm, the surface of the evaporator 40 away from the middle partition plate 20 has a second spacing with the inner wall of the water pan 50 towards the front cover plate 14, the second spacing is any value in 15-25 mm, the depth of the water pan 50 is any value in 25-30 mm, and the width of the water pan 50 is any value in 110-120 mm. The distance between the bottom of the electric control box 81 and the top of the evaporator 40 is any value in 60-65 mm, and the distance between the bottom of the electric control box 81 and the top of the sealing plate 41 is any value in 20-25 mm. Preferably, the first spacing between the evaporator 40 and the front cover plate 14 is 25 mm, the second spacing between the evaporator 40 and the water pan 50 is 20 mm, the depth of the water pan 50 is 28 mm, the width of the water pan 50 is 115 mm, the distance between the bottom of the electric control box 81 and the top of the evaporator 40 is 63 mm, and the distance between the bottom of the electric control box 81 and the top of the sealing plate 41 is 23 mm.

[0053] The person skilled in the art can understand that, if the evaporator 40 is arranged close to the front cover plate 14, the bottom of the evaporator 40 can be blocked by the front cover plate 14 and the water pan 50, and the top of the evaporator 40 can also be affected by the front cover plate 14, resulting in a reduced contact area of the evaporator 40 with the indoor side wind. When the evaporator 40 is moved backward relative to the front cover plate 14, the air volume at the evaporator 40 is increased, which can ensure that the upper and lower ends of the evaporator 40 serve as effective heat exchange areas. Moreover, since the indoor side air volume gradually increases from bottom to top during the process of the indoor side air passing through the evaporator 40 from bottom to top to the indoor fan 61, correspondingly, for the evaporator 40, the air volume on the surface of the evaporator 40 gradually increases from bottom to top, that is, the air field distribution on the surface of the evaporator 40 is uneven. However, when the electric control box 81 is arranged on the indoor side, the upward flow of the indoor air of the evaporator 40 is blocked by the bottom of the electric control box 81, which can cause the air volume at the evaporator 40 to move downward, further utilize the heat exchange area of the bottom of the evaporator 40, and improve the uniformity of the air field on the surface of the evaporator 40, thereby improving the heat exchange efficiency of the evaporator and ensuring the energy efficiency of the air conditioner. Of course, the specific arrangement of the evaporator 40 is not fixed. In an alternative embodiment, the evaporator 40 can be arranged obliquely, for example, the surface of the evaporator 40 is approximately parallel to the partition plate 20, or the evaporator 40 is arranged in a V shape with the partition plate 20. In another alternative embodiment, the evaporator 40 can also be arranged on the front cover plate 14. In addition, the first distance and the second distance are not fixed, and the person skilled in the art can change the first distance between the evaporator 40 and the front cover plate 14, the second distance between the evaporator 40 and the water pan 50, or the mounting mode of the evaporator 40 according to the needs, as long as it does not affect the normal function of the present application. For example, when the bottom of the evaporator 40 is located above the water pan 50 as a whole, the second distance between the evaporator 40 and the water pan 50 can be omitted. Of course, under the premise of considering the limited installation space and drainage condition, it is a better choice to arrange the bottom of the evaporator 40 inside the water pan 50 and set the second distance. In addition, in the present embodiment, the evaporator 40 is arranged as a copper tube-aluminum fin heat exchanger, but the arrangement is not fixed. In an alternative embodiment, the evaporator 40 can be arranged as a micro-channel heat exchanger, which can further improve the heat exchange capacity of the evaporator 40 and improve the energy efficiency of the air conditioner.

[0054] It also needs to be explained that in the present embodiment, the two inner fans 61 are located at the top of the air conditioner, and the two inner fans 61 are set as rear-inclined centrifugal fans, and the angle between the air inlet direction and the air outlet direction of each inner fan 61 is basically 90° when it is running, that is, the air of the inner fan 61 is thrown to the surrounding when it is running, and the air is sent out from the unobstructed side (the front cover plate 14 is opened relative to the air outlet of the inner fan 61) after the cavity where the inner fan 61 is located is full of pressure. The inventor has found through experiments that when the two inner fans 61 run at close range at the same time, there is a wind throwing intersection between the two inner fans 61, which causes the wind field of the two inner fans 61 to influence each other, resulting in wind field turbulence, and further causing the air volume of the two inner fans 61 to decrease, the power consumption to increase, and the air conditioner energy efficiency to decrease. The baffle 63 can reduce the influence of the wind field between the two inner fans 61, increase the pressure of the cavity where the inner fan 61 is located, achieve the effect of reducing interference, and further increase the indoor air volume and improve the air conditioner energy efficiency. At the same time, it can reduce the load of the two inner fans 61 and reduce the required power, further improve the energy efficiency of the air conditioner while reducing noise. In addition, the person skilled in the art can increase the baffle 63 to ensure the air volume on the indoor side while reducing the specifications of the inner fan 61 to reduce costs, and the setting of the baffle 63 can also play a role in concentric positioning of the two inner fans 61, which is conducive to the accurate installation of the two inner fans 61. Of course, the specific setting of the baffle 63 is not immutable, and in an alternative embodiment, the baffle 63 can be omitted. In another alternative embodiment, the person skilled in the art can change the position and installation method of the baffle 63 according to the needs. In another alternative embodiment, the cross-sectional shape of the baffle 63 can be set as T-shaped, and at this time the baffle 63 can be connected to the bracket 62 at the bottom of the inner fan 61 or the bracket above the inner fan 61 only at one end.

[0055] The skilled in the art understands that the specific arrangement of the electric control box 81 is not fixed, in an alternative embodiment, the electric control box 81 is arranged on the indoor side, at this time, the direction of the heat dissipation fin 92 is parallel to the wind direction on the indoor side, at this time, the electric control box 81 can be cooled by the wind on the indoor side, but compared with the outdoor side, the temperature on the indoor side is lower, which is conducive to ensuring the heat dissipation effect of the variable frequency driving part under the super high temperature working condition, and under the premise of considering the influence of the electric control box 81 on the uniformity of the wind field on the surface of the evaporator 40, arranging the electric control box 81 on the indoor side is a relatively optimal choice. In another alternative embodiment, the electric control box 81 can be arranged on the front cover plate 14. In addition, the specific arrangement of the heat dissipation member is also not fixed, in an alternative embodiment, the length direction of the heat dissipation fin 92 can be arranged in a state close to parallel to the wind direction on the indoor side or the outdoor side. Of course, the skilled in the art can also change the size, position of the heat dissipation plate 91 and the height, spacing, length and shape of the heat dissipation fin 92 according to the needs, as long as it does not affect the realization of the normal function of the heat dissipation fin 92. In another alternative embodiment, the heat dissipation plate 91, the heat dissipation fin 92 and the variable frequency driving part can also be omitted, at this time, the energy storage air conditioner can be arranged as a variable frequency air conditioner. In addition, the skilled in the art can also change the distance between the bottom of the electric control box 81 and the top of the evaporator 40 according to the needs, for example, when the front cover plate 14 is arranged as an integral molding, at this time, the arrangement of the sealing plate 41 above the evaporator 40 can be omitted, thereby reducing the distance between the bottom of the electric control box 81 and the top of the evaporator 40.

[0056] The skilled in the art also understands that in order to adapt to the installation requirements of energy storage container and other application scenarios, the energy storage air conditioner needs to be miniaturized and slimmed down, which limits the installation space of various components such as compressors and heat exchangers inside the energy storage air conditioner. Under the influence of the compact installation space, the inclined arrangement of the partition plate 20 can make the indoor side and the outdoor side have large size sections, thereby ensuring the heat exchange area of the condenser 30 and the evaporator 40. Of course, the specific arrangement of the partition plate 20 is not fixed, in an alternative embodiment, the skilled in the art can arrange the inclination angle of the partition plate 20 according to the needs. In another alternative embodiment, the partition plate 20 can include inclined sections above and below and a vertical section in the middle. In another alternative embodiment, the upper end of the partition plate 20 can be connected to the rear cover plate 15, and the lower end of the partition plate 20 can be connected to the front cover plate 14.

[0057] It needs to be explained that in the embodiment, two ends of the water pan 50 are connected to the side panels 13 on both sides respectively, the lower end of the partition plate 20 is connected to the outer wall of the water pan 50, the water pan 50 can collect the condensed water generated in the working process of the evaporator 40, part of the condensed water adheres to the surface of the partition plate 20, so that the part of the condensed water can enter the water pan 50 along the surface of the partition plate 20, the condensed water can be discharged through the drain pipe communicated with the water pan 50, thereby reducing the risk of water entering the internal devices of the energy storage air conditioner and ensuring the normal operation of the energy storage air conditioner, but the specific setting of the water pan 50 is not fixed, in an alternative embodiment, the person skilled in the art can omit the setting of the water pan 50, or change the depth of the water pan 50 according to the needs of the person skilled in the art. In another alternative embodiment, the lower end of the partition plate 20 can be inserted into the water pan 50.
