[0001] The present invention relates to the technical field of air conditioners, and particularly to an energy storage air conditioner. Background Art

[0002] As an integrated energy storage system, an energy storage container can achieve 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 stores energy during power surplus for subsequent use. However, a large amount of heat is generated during the charge and discharge process of the battery in the energy storage system.

[0003] In response to this, the energy storage container is usually equipped with a dedicated energy storage air conditioner to reduce the temperature inside the container and improve the stability of the energy storage system. However, during the adjustment process of the existing energy storage air conditioner, the temperature inside the container may change greatly and become too low. On the one hand, the unreasonable temperature range and temperature difference will affect the safety performance and service life of the battery and have an adverse impact on the energy storage system. On the other hand, it may reduce the energy efficiency of the air conditioner.

[0004] Correspondingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0010] In the case of adopting the above technical solution, the energy storage air conditioner can achieve stable adjustment of the temperature inside the container, thereby improving the energy efficiency of the air conditioner and avoiding the adverse impact of temperature fluctuations on the safety performance of the battery. During the operation of the energy storage air conditioner, the variable frequency drive part generates more heat, and part of the heat dissipation part is exposed to the air duct. Therefore, the outdoor air or indoor air can be used to dissipate heat from the variable frequency drive part through the heat dissipation part, ensuring the normal operation of the energy storage air conditioner.

[0011] In the preferred technical solution of the above energy storage air conditioner, the heat dissipation member includes a heat dissipation plate and heat dissipation fins.

[0013] The spacing between the heat dissipation fins is any value in the range of 6 mm - 7 mm, and the width of the heat dissipation fins is any value in the range of 18 mm - 20 mm.

[0014] In the case of adopting the above technical solution, the heat dissipation fins can ensure the heat dissipation effect while avoiding affecting the wind field uniformity on the indoor side. And when the electronic control box is located on the indoor side, since the temperature on the indoor side is lower, it is beneficial to ensure the heat dissipation effect of the variable frequency drive unit under ultra-high temperature working conditions.

[0015] In the preferred technical solution of the above energy storage air conditioner, it is characterized in that the middle partition is inclined and arranged in the air conditioner housing.

[0016] In the case of adopting the above technical solution, the middle partition can ensure that both the outdoor side and the indoor side have large-size sections, thereby ensuring the heat exchange area on the indoor side and the outdoor side.

[0018] The lower end of the evaporator is close to the lower end in the height direction of the middle partition. The electronic control box is located above the evaporator, and the internal blower is located above the electronic control box and the middle partition.

[0019] In the case of adopting the above technical solution, the wind flowing upward at the evaporator is blocked by the electronic control box above, which can improve the wind field uniformity on the surface of the evaporator and further improve the air conditioner energy efficiency.

[0020] In the preferred technical solution of the above energy storage air conditioner, the evaporator is vertically arranged; and / or

[0022] In the preferred technical solution of the above energy storage air conditioner,

[0023] The distance between the evaporator and the air conditioner housing facing the indoor side is set to any value between 20 mm and 30 mm.

[0024] In the case of adopting the above technical solution, it is beneficial to further improve the wind field uniformity on the surface of the evaporator and ensure the air conditioner energy efficiency.

[0025] In the preferred technical solution of the above energy storage air conditioner, there are two internal fans, the two internal fans are at the same height, and a baffle is arranged between the two internal fans.

[0026] In the case of adopting the above technical solution, the baffle can avoid the turbulent flow problem between the two internal fans, reduce the power required by the two internal fans, increase the air volume and air speed of the indoor side air, and thus reduce the generation of noise while improving the air conditioner energy efficiency.

[0027] In the preferred technical solution of the above energy storage air conditioner, the cross-sectional shape of the baffle is Z-shaped.

[0028] In the case of adopting the above technical solution, the setting of the baffle can play a role in concentric positioning of the two internal fans, which is beneficial to the accurate installation of the two internal fans.

For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0041] As described in the background art, as an integrated energy storage system, the energy storage container can achieve efficient storage and release of energy and can be applied to various application scenarios. For example, in the fields of renewable energy power generation such as wind energy and solar energy, it stores energy during power surplus for subsequent use. However, a large amount of heat is generated during the charging and discharging process of the battery in the energy storage system.

[0042] In this regard, energy storage containers are usually equipped with dedicated energy storage air conditioners to reduce the temperature inside the container and improve the stability of the energy storage system. However, during the adjustment process of existing energy storage air conditioners, the temperature inside the container may change significantly and become too low. On the one hand, an unreasonable temperature range and temperature difference will affect the safety performance and service life of the battery, causing adverse effects on the energy storage system. On the other hand, it may reduce the energy efficiency of the air conditioner.

[0043] To solve the problems of affecting the stability of the energy storage system and low energy efficiency existing in existing energy storage air conditioners, this application provides an energy storage air conditioner, which includes an air conditioner housing; a middle partition board, which is arranged in the air conditioner housing and used to divide the inside of the air conditioner housing into an indoor side and an outdoor side along the thickness direction; an electric control box, in which a variable-frequency drive part is arranged, and the electric control box is located on the indoor side or the outdoor side; a heat dissipation part, at least part of which is located on the back of the electric control box.

[0044] In the case of adopting the above technical solution, the energy storage air conditioner can achieve stable adjustment of the temperature inside the container, thereby improving the energy efficiency of the air conditioner and avoiding adverse effects on the safety performance of the battery caused by temperature fluctuations. During the operation of the energy storage air conditioner, the variable-frequency drive part generates a lot of heat, and the heat dissipation part can realize the heat dissipation of the variable-frequency drive part by outdoor air or indoor air, ensuring the normal operation of the energy storage air conditioner.

[0045] The following refers to Figures 1 to 4 , to describe the energy storage air conditioner of this application. Among them, Figure 1 is the structure diagram of the air conditioner housing of this application; Figure 2 is the side view of the energy storage air conditioner of this application; Figure 3 is the front view of the energy storage air conditioner of this application; Figure 4 is the rear view of the electric control box of this application.

[0046] As Figures 1 to 4As shown in the figure, in a preferred embodiment, the energy storage air conditioner includes an air conditioner housing 10, a middle partition 20, a condenser 30, an evaporator 40, a water receiving tray 50, an internal blower 61, an external blower 70, an electric control box 81, a heat dissipation plate 91, and heat dissipation fins 92. Among them, the air conditioner housing 10 includes a top cover 11, a base 12, side panels 13 on both sides, a front cover plate 14, and a rear cover plate 15. The side panels 13 on both sides, the front cover plate 14, and the rear cover plate 15 are respectively connected to the top cover 11 and the base 12. The space between the top cover 11 and the base 12 forms the height direction of the air conditioner, the space between the side panels 13 on both sides forms the width direction of the air conditioner, and the space between the front cover plate 14 and the rear cover plate 15 forms the thickness direction of the air conditioner. The middle partition 20 is inclined in the air conditioner housing 10, that is, the upper end of the middle partition 20 in the height direction is inclined towards the rear cover plate 15, and the lower end of the middle partition 20 in the height direction is inclined towards the front cover plate 14. Moreover, the inclination angle of the middle partition 20 relative to the vertical direction is any value between 5° and 15°. Preferably, the inclination angle of the middle partition 20 relative to the vertical direction is 10°. The upper end of the middle partition 20 is connected to the mounting plate above the condenser 30, and the lower end of the middle partition 20 is connected to the water receiving tray 50. The middle partition 20 divides the interior of the air conditioner housing 10 in the thickness direction into an indoor side (the side facing the front cover plate 14) and an outdoor side (the side facing the rear cover plate 15). The condenser 30 and the external blower 70 are both located on the outdoor side, and the evaporator 40, the internal blower 61, and the electric control box 81 are all located on the indoor side.

[0047] The upper end of the condenser 30 is close to the upper end of the middle partition 20 in the height direction, and the lower end of the evaporator 40 is close to the lower end of the middle partition 20 in the height direction. In this embodiment, the evaporator 40 is vertically arranged and the bottom of the evaporator 40 is placed in the water receiving tray 50. The evaporator 40 is located between the middle partition 20 and the front cover plate 14. Both sides of the evaporator 40 in the width direction are respectively connected to the side panels 13 on both sides through two mounting plates. Both of the two mounting plates are set as L-shaped plates. Two surfaces of each L-shaped plate are respectively connected to the side of the evaporator 40 facing the front cover plate 14 and the side panel 13 on the corresponding side.

[0048] The internal blower 61 is located above the electronic control box 81 and the middle partition 20. There are two internal blowers 61, and the bottoms of the two internal blowers 61 are both arranged on the bracket 62. A baffle 63 is arranged between the two internal blowers 61 at the same height. The cross-sectional shape of the baffle 63 is roughly Z-shaped, that is, the baffle 63 is vertically arranged between the two internal blowers 61. The upper end of the baffle 63 extends a flange to one side in the width direction, and the lower end of the baffle 63 extends a flange to the other side in the width direction. And the lower end of the baffle 63 is connected to the bracket 62 through the flange, and the upper end of the baffle 63 is connected to the bracket above the internal blower 61 (not shown in the figure) through the flange. The rear cover 15 is provided with an air inlet relative to the external blower 70 and an air outlet relative to the condenser 30. The front cover 14 is provided with an air inlet relative to the evaporator 40 and an air outlet relative to the internal blower 61, that is, the outdoor side air and the indoor side air both flow from bottom to top.

[0049] The electronic control box 81 is located above the evaporator 40, and the electronic control box 81 is located between the middle partition 20 and the front cover 14. The electronic control box 81 is connected to the side panels 13 on both sides through the connecting plates 82 on both sides. Specifically, as Figure 4 shown, the electronic control box 81 forms flanges parallel to the front cover 14 on both sides in the width direction. The connecting plate 82 is set as an L-shaped plate, and the two plate surfaces of the L-shaped plate are respectively connected to the flange of the electronic control box 81 on the corresponding side and the side panel 13 on the corresponding side. A variable frequency drive unit (not shown in the figure) is arranged in the electronic control box 81. The heat dissipation member includes a heat dissipation plate 91 and heat dissipation fins 92. The electronic control box 81 is provided with an opening. The heat dissipation plate 91 is fixedly connected to the inside of the electronic control box 81. The heat dissipation fins 92 pass through the opening and extend out of the back of the electronic control box 81, and the length direction of the heat dissipation fins 92 is parallel to the indoor side wind direction. The variable frequency drive unit is fixedly connected to the heat dissipation plate 91. In this embodiment, the spacing of the heat dissipation fins 92 is any value between 6 mm and 7 mm, the width of the heat dissipation fins 92 is any value between 18 mm and 20 mm, and the length of the heat dissipation fins 92 is less than the length of the heat dissipation plate 91. Preferably, the spacing of the heat dissipation fins 92 is set to 6.5 mm, and the width of the heat dissipation fins 92 is set to 19 mm.

[0050] In this embodiment, during the operation of the energy storage air conditioner, the variable frequency drive unit in the electronic control box 81 may generate a relatively large amount of heat. The heat is transferred to the heat sink 92 through the heat dissipation plate 91. The indoor air is first cooled by the evaporator 40 and then flows upward through the heat sink 92 to dissipate the heat of the electronic control box 81, thereby ensuring the normal operation of the energy storage air conditioner. Additionally, in this embodiment, the evaporator 40 is located between the middle partition 20 and the front cover plate 14, and the distance between the evaporator 40 and the front cover plate 14 is any value within 20 mm - 30 mm. The depth of the water receiving tray 50 is any value within 25 mm - 30 mm, and the width of the water receiving tray 50 is any value within 110 mm - 120 mm. Preferably, the distance between the evaporator 40 and the front cover plate 14 is 25 mm, the depth of the water receiving tray 50 is 28 mm, and the width of the water receiving tray 50 is 115 mm.

[0051] It should be noted that in this embodiment, the electric control box 81 being located on the indoor side means that at least a part of the electric control box 81 is located on the indoor side. For example, those skilled in the art can only arrange 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, but the specific setting of the electric control box 81 is not fixed. In an alternative embodiment, the electric control box 81 is arranged on the outdoor side. At this time, the direction of the heat sink 92 is parallel to the outdoor side wind direction. At this time, the electric control box 81 can be cooled by the outdoor side wind. However, compared with outdoor side heat dissipation, the temperature on the indoor side is lower, which is beneficial to ensuring the heat dissipation effect of the variable frequency drive unit under ultra-high temperature conditions. Therefore, arranging the electric control box 81 on the indoor side is a better choice. In another alternative embodiment, the electric control box 81 can be arranged on the front cover plate 14. In addition, the specific setting of the evaporator 40 is not fixed either. In an alternative embodiment, the evaporator 40 can be inclined. For example, the surface of the evaporator 40 is nearly parallel to the middle partition plate 20, or arranged in a V shape with the middle partition plate 20. In another alternative embodiment, the evaporator 40 can also be arranged on the front cover plate 14. Of course, those skilled in the art can also change the distance between the evaporator 40 and the front cover plate 14 or the installation method of the evaporator 40 according to needs. For example, the evaporator 40 can also be arranged close to the front cover plate 14. Since the indoor side air volume gradually increases from bottom to top during the process of flowing through the evaporator 40 to the indoor fan 61 from bottom to top, 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, and the upper side air may flow downward after being blocked, thereby increasing the contact area between the indoor side air and the evaporator 40 and improving the air field uniformity on the surface of the evaporator 40. In addition, when the evaporator 40 is arranged close to the front cover plate 14, the bottom of the evaporator 40 may be blocked by the front cover plate 14 and the water receiving tray 50, resulting in a reduction in the contact area between the evaporator 40 and the indoor side air. After verification by the inventor, when the evaporator 40 is moved backward relative to the front cover plate 14, that is, there is a distance between the side of the evaporator 40 facing the front cover plate 14 and the front cover plate 14, the contact area between the evaporator 40 and the indoor side air increases, the air volume at the evaporator 40 increases, and after the upward flow of the indoor air passing through the evaporator 40 is blocked, the pressure may cause the air volume at the evaporator 40 to move downward, thereby making full use of the heat exchange area at the bottom of the evaporator 40 and further improving the air field uniformity on the surface of the evaporator 40, thereby improving the heat exchange efficiency of the evaporator and ensuring the air conditioner energy efficiency. Therefore, arranging the electric control box 81 on the indoor side and moving the evaporator 40 backward relative to the front cover plate 14 is a better choice.In addition, in this embodiment, the evaporator 40 is configured as a copper tube-aluminum fin heat exchanger, but its configuration is not fixed. In an alternative embodiment, the evaporator 40 can be configured as a microchannel heat exchanger, which can further increase the heat transfer capacity of the evaporator 40 and thus improve the air-conditioning energy efficiency.

[0052] It should also be explained that in this embodiment, both of the two internal fans 61 are located at the top of the air conditioner, and both of the two internal fans 61 are configured as backward-inclined centrifugal fans. When each internal fan 61 operates, the included angle between the air inlet direction and the air outlet direction is basically 90°. That is to say, when the internal fan 61 operates, the air will be thrown around. After the cavity where the internal fan 61 is located is filled with pressure, the air flows out to the side without resistance (the air outlet on the front cover 14 relative to the internal fan 61). Through experiments by the inventor, it is known that when the two internal fans 61 operate simultaneously at a short distance, there is an air throwing intersection between the two internal fans 61, resulting in the mutual influence of the air fields of the two internal fans 61, the occurrence of air field turbulence, and further the reduction of the air volume of the two internal fans 61, the increase of power consumption, and the reduction of the air-conditioning energy efficiency. By means of the baffle 63, the influence of the air fields between the two internal fans 61 can be reduced, the pressure of the cavity where the internal fan 61 is located can be increased, the effect of reducing interference can be achieved, and thus the indoor-side air volume can be increased, the air-conditioning energy efficiency can be improved. At the same time, the load of the two internal fans 61 can be reduced, the required power can be decreased, the air-conditioning energy efficiency can be further improved, and the generation of noise can be reduced. In addition, those skilled in the art can, when reducing the specifications of the internal fan 61 to reduce costs, ensure the indoor-side air volume by adding the baffle 63, and the setting of the baffle 63 can also play a role in concentric positioning of the two internal fans 61, which is beneficial to the accurate installation of the two internal fans 61. Of course, the specific setting of the baffle 63 is not fixed. In an alternative embodiment, the baffle 63 can be omitted. In another alternative embodiment, those skilled in the art can change the position and installation method of the baffle 63 according to requirements. In another alternative embodiment, the cross-sectional shape of the baffle 63 can be set as a T shape. At this time, the baffle 63 can be connected to the bracket 62 at the bottom of the internal fan 61 or the bracket above the internal fan 61 only at one end.

[0053] Those skilled in the art understand that the specific setting of the heat dissipation component is not fixed either. In an alternative embodiment, the length direction of the heat sink 92 can be set to be nearly parallel to the wind direction on the indoor side or the outdoor side. Of course, those 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 sink 92 according to requirements, as long as the normal function of the heat sink 92 is not affected. In addition, to meet the installation requirements of application scenarios such as energy storage containers, the energy storage air conditioner needs to be miniaturized and thinner, which makes the installation space for various components such as the compressor and heat exchanger inside the energy storage air conditioner relatively limited. Under the influence of the compact installation space, the middle partition 20 is inclined, which can make both the indoor side and the outdoor side have large-size segments, thereby ensuring the heat exchange area of the condenser 30 and the evaporator 40. Of course, the specific setting of the middle partition 20 is not fixed either. In an alternative embodiment, those skilled in the art can set the inclination angle of the middle partition 20 according to requirements. In another alternative embodiment, the middle partition 20 can include inclined segments at the upper and lower parts and a vertical segment in the middle. In another alternative embodiment, the upper end of the middle partition 20 can be connected to the rear cover plate 15, and the lower end of the middle partition 20 can be connected to the front cover plate 14.

[0054] It should be explained that in this embodiment, both ends of the water receiving tray 50 are respectively connected to the side panels 13 on both sides. The lower end of the middle partition 20 is inserted into the water receiving tray 50 and connected to the water receiving tray 50. The water receiving tray 50 can collect the condensed water generated during the operation of the evaporator 40. Part of the condensed water adheres to the surface of the middle partition 20. Therefore, this part of the condensed water can enter the water receiving tray 50 along the surface of the middle partition 20, and the condensed water can be discharged through the drain pipe communicated with the water receiving tray 50, thereby reducing the hidden danger of water ingress into the internal components of the energy storage air conditioner and ensuring the normal operation of the energy storage air conditioner. However, the specific setting of the water receiving tray 50 is not fixed either. In an alternative embodiment, those skilled in the art can omit the setting of the water receiving tray 50, or change the depth of the water receiving tray 50 according to the needs of those skilled in the art. In another alternative embodiment, the lower end of the middle partition 20 can be arranged outside the water receiving tray 50 and connected to the water receiving tray 50.

[0055] Those skilled in the art can understand that although some embodiments herein include certain features included in other embodiments rather than other features, the combination of the features of different embodiments means that it is within the scope of this application and forms different embodiments. For example, in the claims of this application, any one of the claimed embodiments can be used in any combination.

[0056] So far, the technical solution of the present application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easily understood by those skilled in the art that the protection scope of the present application is obviously not limited to these specific embodiments.
