Description

Technical Field

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

[0002] As an integrated energy storage system, energy storage containers can achieve efficient storage and release of energy and can be applied to a variety of application scenarios. For example, in the field of renewable energy generation such as wind power and solar power, when there is excess electricity, it can be stored for subsequent use. However, the batteries in the energy storage system will generate a lot of heat during the charging and discharging process. In order to extend the service life of the battery and improve the stability of the energy storage system, energy storage containers usually need to be equipped with special energy storage air conditioners such as door-mounted air conditioners to adjust the temperature inside the container.

[0003] In order to adapt to the installation requirements of application scenarios such as energy storage containers, energy storage air conditioners need to be miniaturized and slim, which makes the installation space of various components such as compressors and heat exchangers inside the energy storage air conditioner relatively limited. Under the influence of the compact installation space, the indoor side air duct may also affect the uniformity of the wind field due to limited space, making it impossible to fully utilize the evaporator and affecting the heat exchange efficiency of the energy storage air conditioner, thereby reducing the energy efficiency of the air conditioner.

[0004] Accordingly, the art needs a new technical solution to solve the above problems. Summary of the invention

[0005] In order to solve at least one of the above problems in the prior art, that is, to solve the problem of low wind field uniformity and low energy efficiency caused by limited installation space of the existing energy storage air conditioner, the present application provides an energy storage air conditioner, which includes:

[0006] Air conditioning housing;

[0007] A middle partition, which is arranged on the air-conditioning housing and is used to separate the interior of the air-conditioning housing into an indoor side and an outdoor side along a thickness direction;

[0008] an evaporator, the evaporator being located on the indoor side, and having a first distance between a surface of the evaporator facing away from the middle partition and the air conditioning housing facing the indoor side;

[0009] An internal fan is located inside the room and above the evaporator.

[0010] When the above technical solution is adopted, the indoor side wind enters from the air-conditioning shell corresponding to the evaporator and is blown out from the air-conditioning shell corresponding to the internal fan. The air volume on the evaporator surface gradually increases from bottom to top. By setting the first spacing, the influence of the top and bottom of the evaporator being blocked by the air-conditioning shell can be reduced, ensuring that the upper and lower ends of the evaporator serve as effective heat exchange areas, and increasing the air volume at the bottom of the evaporator, thereby improving the uniformity of the wind field on the evaporator surface, ensuring the heat exchange efficiency of the evaporator, and improving the energy efficiency of the energy storage air conditioner.

[0011] In the preferred technical solution of the above energy storage air conditioner, the evaporator is arranged vertically; and / or

[0016] When the above technical solution is adopted, it is beneficial to fully utilize the performance of each heat exchanger in the air conditioner through the specific angles of each part of the middle partition.

[0017] In the preferred technical solution of the above energy storage air conditioner, the energy storage air conditioner further comprises a water receiving pan, and the water receiving pan is located below the evaporator;

[0018] The lower end of the middle partition in the height direction is connected to the water receiving tray.

[0019] When the above technical solution is adopted, the condensed water generated during the working process of the evaporator can be collected through the water receiving tray and discharged, thereby reducing the hidden danger of water intrusion into the internal components of the energy storage air conditioner and ensuring the normal operation of the air conditioner.

[0020] In the preferred technical solution of the above energy storage air conditioner, the lower end of the evaporator is located in the water receiving tray, and there is a second distance between the surface of the evaporator facing away from the middle partition and the inner wall of the water receiving tray facing the indoor side.

[0021] When the above technical solution is adopted, when the indoor side wind enters the air-conditioning casing, the setting of the second spacing can ensure that the inner wall of the water receiving tray will not block the bottom of the evaporator, thereby ensuring the heat exchange efficiency of the evaporator and improving the energy efficiency of the energy storage air conditioner.

[0022] In the preferred technical solution of the above energy storage air conditioner, the second spacing is any value within 15 mm - 25 mm; and / or

[0023] the depth of the water receiving tray is any value within 25 mm - 30 mm; and / or

[0024] the width of the water receiving tray is any value within 110 mm - 120 mm.

[0025] Adopting the above technical solution is beneficial to ensuring the drainage effect of the water receiving tray while guaranteeing the uniformity of the air flow field on the surface of the evaporator.

[0026] In the preferred technical solution of the above energy storage air conditioner, the energy storage air conditioner includes an electric control box, the electric control box is located on the indoor side, and the electric control box is located above the evaporator.

[0027] In the preferred technical solution of the above energy storage air conditioner, the distance between the bottom of the electric control box and the top of the evaporator is any value within 60 mm - 65 mm; and / or

[0029] Adopting the above technical solution, the upward flowing air at the evaporator is blocked by the electric control box above, which can improve the uniformity of the air flow field on the surface of the evaporator and further improve the energy efficiency of the air conditioner.

[0030] 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.

[0031] 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 energy efficiency of the air conditioner.

[0039] The preferred implementation manners of the present application will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present application and are not intended to limit the protection scope of the present application. For example, although the electric control box in the drawings is disposed on the indoor side of the energy storage air conditioner, this positional relationship is not fixed. Those skilled in the art can adjust it according to needs to adapt to specific application scenarios. For example, the electric control box can be disposed on the outdoor side of the energy storage air conditioner.

[0040] It should be noted that in the description of the present application, the terms indicating directions or positional relationships such as "up", "down", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, "a plurality of" means at least two.

[0041] In addition, it should also be noted that in the description of the present application, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0042] As described in the background art, 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. During the charging and discharging process of the battery in the energy storage system, a large amount of heat is generated. To extend the service life of the battery and improve the stability of the energy storage system, the energy storage container usually needs to be equipped with a dedicated energy storage air conditioner, such as a door-mounted air conditioner, to adjust the temperature inside the container.

[0043] To meet the installation requirements of application scenarios such as energy storage containers, the energy storage air conditioner needs to be miniaturized and thinned, which makes the installation space for various components such as compressors and heat exchangers inside the energy storage air conditioner relatively limited. Under the influence of the compact installation space, the indoor air duct may also be affected by the limited space, resulting in uneven wind field and affecting the heat exchange efficiency of the evaporator due to the insufficient utilization of the evaporator, thereby reducing the energy efficiency of the air conditioner.

[0044] To solve the problems of low wind field uniformity and low energy efficiency caused by limited installation space in existing energy storage air conditioners, the present application provides an energy storage air conditioner, which includes an air conditioner housing; a middle partition plate disposed in the air conditioner housing for dividing the interior of the air conditioner housing in the thickness direction into an indoor side and an outdoor side; an evaporator located on the indoor side, with a first distance provided between the surface of the evaporator and the air conditioner housing facing the indoor side; and an internal blower located on the indoor side and above the evaporator.

[0045] In the case of adopting the above technical solution, the indoor air enters from the air conditioner housing corresponding to the evaporator and blows out from the air conditioner housing corresponding to the internal blower. The air volume on the surface of the evaporator gradually increases from bottom to top. By setting the first distance, the influence of the air conditioner housing blocking the top and bottom of the evaporator can be reduced, ensuring that the upper and lower ends of the evaporator are effective heat exchange areas, and the air volume at the bottom of the evaporator can also be increased, thereby improving the wind field uniformity on the surface of the evaporator, ensuring the heat exchange efficiency of the evaporator, and improving the energy efficiency of the energy storage air conditioner.

[0046] The following refers to Figures 1 to 4 , to describe the energy storage air conditioner of the present application. Among them, Figure 1 is the structural diagram of the air conditioner housing of the present application; Figure 2 is the side view of the energy storage air conditioner of the present application; Figure 3 is the front view of the energy storage air conditioner of the present application; Figure 4 is the rear view of the electric control box of the present application.

[0047] As Figures 1 to 4As shown, 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, the front cover plate 14, and the rear cover plate 15 on both sides are respectively connected to the top cover 11 and the base 12. And in this embodiment, the front cover plate 14 includes a first cover body 141 above and a second cover body 142 below. The first cover body 141 covers the top cover 11 and the side panels 13 on both sides, and the second cover body 142 covers the side panels 13 on both sides and the base 12. The space between the top cover 11 and the base 12 constitutes the height direction of the air conditioner, the space between the side panels 13 on both sides constitutes the width direction of the air conditioner, and the space between the front cover plate 14 and the rear cover plate 15 constitutes 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 backward toward the rear cover plate 15, and the lower end of the middle partition 20 in the height direction is inclined forward toward the front cover plate 14. And 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.

[0048] 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. The two sides in the width direction of the evaporator 40 are respectively connected to the side panels 13 on both sides through two mounting plates. Both of the two mounting plates are L-shaped plates. Two plate 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. As Figure 3 shown, in this embodiment, a sealing plate 41 is arranged above the evaporator 40. The sealing plate 41 is integrally L-shaped. Its bottom abuts against the upper end of the evaporator 40. The two sides of the sealing plate 41 are respectively connected to the side panels 13 on both sides. A plurality of connection holes are formed on the side of the sealing plate 41 close to the front cover plate 14. The sealing plate 41 is connected to the first cover body 141 and the second cover body 142 of the front cover plate 14 through the plurality of connection holes. That is, the sealing plate 41 is used to seal the joint position of the first cover body 141 and the second cover body 142.

[0049] 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 generally 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. An air inlet relative to the external blower 70 and an air outlet relative to the condenser 30 are provided on the rear cover plate 15, and an air inlet relative to the evaporator 40 and an air outlet relative to the internal blower 61 are provided on the front cover plate 14, that is, the outdoor side air and the indoor side air both flow from bottom to top.

[0050] 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 plate 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 plate 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.

[0051] In this embodiment, during the operation of the energy storage air conditioner, the variable frequency drive unit in the electric 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 electric control box 81, thereby ensuring the normal operation of the energy storage air conditioner. And the electric control box 81 being located on the indoor side means that at least 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. In addition, in this embodiment, the evaporator 40 is located between the middle partition 20 and the front cover plate 14, and there is a first distance between the surface of the evaporator 40 facing away from the middle partition 20 and the front cover plate 14. The first distance is any value between 20 mm and 30 mm. There is a second distance between the surface of the evaporator 40 facing away from the middle partition 20 and the inner wall of the water receiving tray 50 facing the front cover plate 14. The second distance is any value between 15 mm and 25 mm. The depth of the water receiving tray 50 is any value between 25 mm and 30 mm. The width of the water receiving tray 50 is any value between 110 mm and 120 mm. The distance between the bottom of the electric control box 81 and the top of the evaporator 40 is any value between 60 mm and 65 mm. The distance between the bottom of the electric control box 81 and the top of the sealing plate 41 is any value between 20 mm and 25 mm. Preferably, the first distance between the evaporator 40 and the front cover plate 14 is 25 mm, the second distance between the evaporator 40 and the water receiving tray 50 is 20 mm, the depth of the water receiving tray 50 is 28 mm, the width of the water receiving tray 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.

[0052] Those 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 may be blocked by the front cover plate 14 and the water receiving tray 50, and the top of the evaporator 40 may also be affected by the front cover plate 14, resulting in a reduction in the contact area between the evaporator 40 and the indoor side air. When the evaporator 40 is moved backward relative to the front cover plate 14, the air volume at the evaporator 40 increases, which can ensure that the upper and lower ends of the evaporator 40 are used as effective heat exchange areas. And since the indoor side air gradually increases in volume from bottom to top during the process of passing through the evaporator 40 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 electronic control box 81 is arranged on the indoor side, the upward flow of the indoor air at the evaporator 40 is blocked by the bottom of the electronic control box 81, and the pressure may cause the air volume at the evaporator 40 to move downward, further making full use of the heat exchange area at the bottom of the evaporator 40 and 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. Of course, the specific arrangement of the evaporator 40 is not fixed. In an alternative implementation, the evaporator 40 can be arranged obliquely. For example, the surface of the evaporator 40 is nearly parallel to the middle partition plate 20, or is arranged in a V shape with the middle partition plate 20. In another alternative implementation, the evaporator 40 can also be arranged on the front cover plate 14. In addition, the settings of the first distance and the second distance are not fixed either. Those skilled in the art can also change the first distance between the evaporator 40 and the front cover plate 14, the second distance between the evaporator 40 and the water receiving tray 50, or the installation method of the evaporator 40 according to requirements, as long as the normal functions of this application are not affected. For example, when the bottom of the evaporator 40 is located above the entire water receiving tray 50, the setting of the second distance between the evaporator 40 and the water receiving tray 50 can be omitted at this time. Of course, on the premise of considering limited installation space and drainage conditions, placing the bottom of the evaporator 40 inside the water receiving tray 50 and setting the second distance is a better choice. In addition, in this embodiment, the evaporator 40 is set as a copper tube-aluminum fin heat exchanger, but its setting is not fixed. In an alternative implementation, the evaporator 40 can be set as a microchannel heat exchanger, and at this time, the heat exchange capacity of the evaporator 40 can be further increased, thereby improving the air conditioner energy efficiency.

[0053] 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 set as backward-inclined centrifugal fans. When each internal fan 61 is operating, 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 is operating, the air will be thrown around. After the cavity where the internal fan 61 is located is filled with pressure, the air will be sent to the side without resistance (the air outlet on the front cover plate 14 relative to the internal fan 61). Through the experiments by the inventor, it is known that when the two internal fans 61 are operating 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, causing air field turbulence, and further resulting in the reduction of the air volume of the two internal fans 61, the increase of power consumption, and the reduction of the air conditioner energy efficiency. By means of the baffle 63, the influence of the air field 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 further the indoor side air volume can be increased, the air conditioner 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 reduced, and the noise generation can be reduced while further improving the air conditioner energy efficiency. In addition, those skilled in the art can ensure the indoor side air volume by adding the baffle 63 when reducing the specifications of the internal fan 61 to reduce costs. Moreover, 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.

[0054] Those skilled in the art understand that the specific setting of the electronic control box 81 is not fixed. In an alternative implementation, the electronic control box 81 is arranged on the outdoor side. At this time, the direction of the heat sink 92 is parallel to the outdoor wind direction. At this time, the electronic control box 81 can be cooled by the outdoor wind. However, compared with outdoor cooling, 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. And on the premise of considering the influence of the electronic control box 81 on the wind field uniformity on the surface of the evaporator 40, arranging the electronic control box 81 on the indoor side is a better choice. In another alternative implementation, the electronic control box 81 can be arranged on the front cover plate 14. In addition, the specific setting of the heat dissipation component is not immutable either. In an alternative implementation, the length direction of the heat sink 92 can be set to be nearly parallel to the indoor or outdoor wind direction. 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 another alternative implementation, the heat dissipation plate 91, the heat sink 92, and the variable frequency drive unit can also be omitted. At this time, the energy storage air conditioner can be set as a variable frequency air conditioner. In addition, those skilled in the art can also change the distance between the bottom of the electronic control box 81 and the top of the evaporator 40 according to requirements. For example, when the front cover plate 14 is integrally formed, the setting of the sealing plate 41 above the evaporator 40 can be omitted at this time, thereby reducing the distance between the bottom of the electronic control box 81 and the top of the evaporator 40.

[0055] Those skilled in the art can also understand that to meet the installation requirements of application scenarios such as energy storage containers, the energy storage air conditioner needs to be miniaturized and slimmed down. This 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 to enable both the indoor side and the outdoor side to have large-sized sections, 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 implementation, those skilled in the art can set the inclination angle of the middle partition 20 according to requirements. In another alternative implementation, the middle partition 20 can include inclined sections at the upper and lower parts and a vertical section in the middle. In another alternative implementation, 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.

[0056] It should be noted that, in this embodiment, both ends of the water receiving tray 50 are respectively connected to the side panels 13 on both sides, and the lower end of the middle partition plate 20 is connected to the outer wall of 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 plate 20. Therefore, this part of the condensed water can enter the water receiving tray 50 along the surface of the middle partition plate 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 plate 20 can be inserted into the water receiving tray 50.
