Description

Technical Field

[0001] This invention relates to the field of refrigeration technology, and more specifically to a precision air conditioner for a data center with a humidifying membrane. Background Technology

[0002] Precision air conditioning in data centers typically uses in-row air conditioning systems, where the indoor units need to have a certain humidification function. Currently, air conditioning humidification methods are mainly divided into electrode humidification and humidification film humidification. Humidification film humidification is more cost-effective than electrode humidification, therefore it has become the preferred solution for major air conditioning manufacturers. The humidification capacity of humidification film humidification mainly depends on the size of the humidification film; the larger the film, the stronger its humidification capacity. Currently, the humidification capacity of indoor air conditioners with a power of 35KW or less is mainly 1.5kg / h. However, with increasingly fierce market competition, the demand for humidification capacity is also increasing. But a larger humidification capacity also means a larger volume of humidifying film. In existing indoor air conditioners with humidification function, the humidifying film is usually placed above the compressor and parallel to the side panel of the cabinet. The compressor makes the installation space for the humidifying film small, and the humidifying film is a fragile item that needs to be replaced after a period of use. For a small installation space, disassembly or installation often requires disassembling both the side panel near the humidifying film and the front panel perpendicular to the side panel, making the disassembly and assembly steps cumbersome. Due to the limitations of the compressor, for indoor air conditioners with a fixed width, the length and width of the humidifying film cannot be increased, which means it is difficult to obtain a larger humidification capacity. In addition, since the humidifying film will seep water downwards, a drip tray needs to be placed at the bottom of the humidifying film. There is also a drip tray at the bottom of the evaporator inside the air conditioner. That is to say, there are two drip trays inside an air conditioner, resulting in more piping. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects or problems in the prior art and to provide a precision air conditioner for a data center with a humidifying film, which is easy to install and remove and has a large humidification capacity.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Technical Solution 1: A precision air conditioner for a data center with a humidifying film, comprising: a cabinet having a first side panel and a second side panel arranged parallel to each other and opposite to each other along a first direction, the first side panel and the second side panel respectively having an air inlet and an air outlet; an evaporator installed in the cabinet and having an air inlet surface and an air outlet surface arranged parallel to each other along a second direction, the second direction being inclined relative to the first direction; a water receiving tray located below the evaporator and having a water receiving surface; a fan installed in the cabinet near the second side panel and used to drive air to flow from the air inlet, the air inlet surface, the air outlet surface to the air outlet; and a humidifying component placed above the water receiving surface and located between the air inlet surface of the evaporator and the first side panel, comprising a mounting bracket and connecting parts. The device comprises a support member and a humidifying membrane; the mounting bracket is fixed to the evaporator and extends along a third direction perpendicular to the second direction, and the mounting bracket has an abutment surface on the side opposite to the air inlet surface; the connector is detachably fixed to the mounting bracket and adapted to cooperate with the abutment surface to form a downward-opening slot; the support member is fixed to the water receiving tray and has an upward-opening positioning groove and at least one guide surface extending upwardly at the edge of the self-positioning groove; the humidifying membrane is parallel to the air inlet surface, its bottom end is adapted to be inserted into the positioning groove through the guide surface, and its top end is adapted to abut the abutment surface and be inserted into the slot; an installation channel suitable for the humidifying membrane to enter and exit is also formed between the air inlet surface and the first side plate.

[0006] Based on technical solution one, there is also technical solution two. In technical solution two, the evaporator has two vertically extending mounting surfaces on both sides along a third direction, and the two ends of the mounting bracket are respectively locked to the two mounting surfaces.

[0007] Based on technical solution two, technical solution three is also provided. In technical solution three, the mounting bracket has a groove extending in a third direction with the groove opening facing away from the air inlet surface, two connecting parts located at both ends of the groove, and an abutting wall; the bottom wall of the groove is parallel to the air inlet surface and forms a gap with the air inlet surface, and the bottom wall of the groove is also provided with a plurality of first air passage holes in a third direction; the connecting part is adapted to be locked to the mounting surface; the abutting wall extends downward from the free end of the groove side wall below the groove, and the abutting surface is formed on the abutting wall.

[0008] Based on technical solution three, there is also technical solution four. In technical solution four, the connector extends along a third direction and is stepped. It has a first wall, a second wall, a third wall and a fourth wall connected in sequence. The first wall is adapted to be locked with the groove side wall above the groove. The second wall corresponds to the groove opening and has a plurality of second air passage holes arranged along a third direction. The third wall and the fourth wall cooperate with the abutment wall to form the slot. The third wall forms the bottom of the slot.

[0009] Based on technical solution four, there is also technical solution five, in which the connector is further provided with a buffer layer on the lower surface of the third wall.

[0010] Based on technical solution one, there is also technical solution six. In technical solution six, the support member is a long strip-shaped open box structure that extends along a third direction. It has a box body, several folded edges and a first mounting part. The inner cavity of the box body forms the positioning groove. Each folded edge extends obliquely from the opening edge of the box body relative to the vertical direction and forms the guide surface. The first mounting part is located on the side of the box body away from the air inlet surface and is suitable for locking with the water receiving tray.

[0011] Based on technical solution six, technical solution seven is also provided. In technical solution seven, the water receiving tray has an upward-opening receiving groove and a second mounting part. The water receiving surface is formed at the bottom of the receiving groove, and the second mounting part protrudes from the groove wall of the receiving groove. The first mounting part and the second mounting part are locked together. The support member also has a plurality of positioning parts arranged in a third direction on the side away from the air inlet surface. The positioning parts are adapted to abut against the groove wall of the receiving groove.

[0012] Based on technical solution seven, there is also technical solution eight. In technical solution eight, the support member is suspended above the water receiving surface, and the bottom wall of the positioning groove is provided with a number of drainage holes along a third direction.

[0013] Based on technical solution one, there is also technical solution nine. Technical solution nine further includes a compressor, a liquid storage tank, and an electrical control box located between the air inlet surface and the air inlet. The compressor and the liquid storage tank are placed at the bottom of the cabinet, and the electrical control box is located above the compressor and the liquid storage tank. The gaps between the air inlet surface, the compressor, the liquid storage tank, and the electrical control box, as well as the gaps between them and the cabinet, form the installation channel.

[0014] Based on technical solution nine, there is also technical solution ten. In technical solution ten, the bottom of the evaporator is provided with a drainage surface, which is suspended above the water receiving surface.

[0015] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In Technical Solution 1, when installing the humidifying membrane, the first side panel of the cabinet is removed, the humidifying membrane is placed inside the cabinet and positioned above the positioning slot along the installation channel. The bottom end of the humidifying membrane can then smoothly insert into the positioning slot through the guide surface, and the top end of the humidifying membrane abuts against the contact surface. Then, the connector is attached close to the top end of the humidifying membrane and fixed to the mounting bracket, and the top end of the humidifying membrane is inserted into the slot, completing the installation. When maintenance of the humidifying membrane is required, the first side panel of the cabinet is removed, the connector is detached from the mounting bracket, and then the humidifying membrane is pulled upwards until the bottom end of the humidifying membrane comes out of the positioning slot. The humidifying membrane can then be moved along the installation channel. Remove the humidifying membrane from the side where the first side panel is located, then replace it with a new one and install it as described above. During use, the fan drives air to flow from the air inlet, through the humidifying membrane, the air inlet surface, and the air outlet surface to the air outlet. Because the humidifying membrane is located on the air inlet side of the evaporator, the airflow temperature on the air inlet side is higher. The water in the humidifying membrane can evaporate through the evaporator and become water vapor, flowing to the air outlet, thus improving the steam humidification efficiency. It can be seen that with this technical solution, the positioning groove can not only position and support the humidifying membrane but also allow for blind insertion of the bottom end of the humidifying membrane. After insertion, the humidifying membrane can be basically positioned by abutting the contact surface, and then connected by the connector... This design allows the humidifying film to be confined at its top and bottom ends and in other directions. Therefore, installation or disassembly only requires removing the first side panel of the cabinet, eliminating the need to remove the side and front panels as in existing technologies. This makes maintenance much more convenient, especially during installation, as the bottom of the humidifying film can essentially fall into the positioning groove automatically under gravity, eliminating the need for a separate observation window or front panel removal, saving effort and time. Because the evaporator's air inlet and outlet surfaces are arranged along a second direction, which is inclined relative to the first direction, and the humidifying film is parallel to the air inlet surface, both the evaporator and the humidifying film are placed at an angle within the cabinet. Compared to placing the evaporator and humidifying film perpendicular to the airflow direction above the compressor, the inclined air inlet side of the evaporator provides more installation space for both. This allows for larger volumes of the evaporator and humidifying film, and the compressor only needs to provide an installation channel for the humidifying film. This enables the convenient placement of a high-capacity humidifying film in a smaller space. The connectors can also apply pressure to the humidifying film to prevent water leakage. The drip tray can simultaneously collect condensate from the evaporator and water leakage from the humidifying film. The ingenious structure results in fewer pipes and ensures stable operation of the internal components of the air conditioner.

[0017] 2. In technical solution two, since the evaporator often needs to be connected to the pump or compressor in actual use, there are many pipelines. In this application, the installation surfaces are set on both sides of the air inlet surface of the evaporator, which neither occupies the ventilation area nor interferes with the pipelines, and the structure is ingenious.

[0018] 3. In technical solution three, the structure of the mounting bracket is simple and easy to manufacture and install. The bottom wall of the groove is parallel to the air inlet surface and forms a gap with the air inlet surface, which can prevent the mounting bracket from blocking the air inlet surface of the evaporator. At the same time, the bottom wall of the groove is also provided with a first air passage hole. The setting of the first air passage hole can further prevent the mounting bracket from blocking the wind, thereby increasing the effective heat exchange area of ​​the evaporator.

[0019] 4. In technical solution four, the structure of the connector is easy to disassemble and assemble. The setting of the second air passage avoids reducing the air volume of the evaporator, and achieves the fixation of the humidifying film with minimal impact on the evaporator and the humidifying film. The first wall is locked to the groove side wall of the groove, which is easier to operate.

[0020] 5. In technical solution five, the buffer layer can prevent damage to the humidifying membrane.

[0021] 6. In technical solution six, the structure of the support component is simple and easy to process.

[0022] 7. In technical solution seven, the first and second mounting parts are locked in place, making operation easier; the positioning part prevents the swaying of the support from damaging the humidifying membrane.

[0023] 8. In technical solution eight, the support is suspended above the water surface, and the bottom wall of the positioning groove is provided with several drainage holes along the third direction, which facilitates water seepage and protects the humidifying membrane from damage.

[0024] 9. In technical solution nine, the compressor, liquid storage tank, and electrical control box are positioned for easy disassembly and assembly of the humidifying membrane. When installing the humidifying membrane, remove the first side panel of the cabinet, place the humidifying membrane inside the cabinet, and insert it along the gap between the electrical control box and the rear panel. Then, position the humidifying membrane above the positioning slot along the gap between the liquid storage tank and the compressor and the rear panel. The bottom end of the humidifying membrane can then smoothly insert into the positioning slot through the guide surface, with the top end abutting against the contact surface. Next, attach the connector close to the top of the humidifying membrane and secure it to the mounting bracket. The top end of the humidifying membrane is then inserted into the slot, completing the installation. When maintenance of the humidifying membrane is required, remove the first side panel of the cabinet and detach the connector from the mounting bracket. Then, pull the humidifying membrane upwards until the bottom end of the humidifying membrane comes out of the positioning slot. Next, move the humidifying membrane along the gap between the liquid storage tank and the compressor and the rear panel to the side of the cabinet closest to the first side panel. Then, pull the humidifying membrane upwards and remove it along the gap between the electrical control box and the rear panel. Replace with a new humidifying membrane and install it using the above method.

[0025] 10. In technical solution ten, the bottom of the evaporator is located on the drain surface, which is suspended above the water receiving surface, making it easy for the evaporator to drain water. Attached Figure Description

[0042] See Figure 1-8 , Figure 1-8 A precision air conditioner for a data center with a humidifying membrane is shown, including a cabinet 10, an evaporator 20, a water tray 30, a fan 40, a humidifying component, a compressor 60, a liquid storage tank 70, and an electrical control box 80.

[0043] The cabinet 10 has a first side panel 11 and a second side panel 12 arranged parallel to each other and opposite to each other along a first direction. The first side panel 11 and the second side panel 12 are respectively provided with an air inlet 111 and an air outlet 121. The cabinet 10 has a front panel 13 and a rear panel 14 arranged along a fourth direction perpendicular to the first direction. The cabinet 10 is roughly rectangular, with its length direction being the first direction and its width direction being the fourth direction. In actual use, the cabinet 10 can be constructed from columns and sheet metal. In this embodiment, the first direction is the left-right direction, and the fourth direction is the front-back direction.

[0044] See Figure 3-5 The evaporator 20 is installed inside the cabinet 10 and has parallel air inlet surfaces 21 and air outlet surfaces 22 arranged along a second direction. The second direction is inclined relative to the first direction. The evaporator 20 has two vertically extending mounting surfaces 23 on both sides along a third direction perpendicular to the second direction. The mounting surfaces 23 are inclined relative to the second direction. In this embodiment, the evaporator 20 is generally long plate-shaped. The length direction of the evaporator 20 is the third direction, and the width direction of the evaporator 20 is the second direction. The evaporator 20 is placed vertically inside the cabinet 10. The two ends of the evaporator 20 in the third direction are close to the front and rear panels of the cabinet 10, respectively. Sheet metal is provided at both ends of the evaporator 20. One side of the sheet metal along the second direction protrudes from the air inlet surface 21 of the evaporator 20 and forms the mounting surface 23. That is, the mounting surface 23 is located upstream of the air inlet surface 21.

[0045] The evaporator 20 has a drain surface 241 at its bottom, which is suspended above the water receiving surface 311. For actual use, please refer to... Figure 5-6 The evaporator 20 is placed on a support frame 24, which is formed by a support plate and support feet located at the bottom of the support plate. The support plate extends along a third direction and is provided with a number of water passage holes along the third direction to form a drainage surface 241.

[0046] The water receiving tray 30 is located below the evaporator 20 and has a water receiving surface 311. In a specific implementation, the water receiving tray 30 has an upward-opening receiving groove 31 and a second mounting part 32. The water receiving surface 311 is formed at the bottom of the receiving groove 31, and the second mounting part 32 protrudes from the groove wall of the receiving groove 31. The second mounting part 32 is close to the front of the cabinet 10 and located on the air inlet side of the evaporator 20.

[0047] The fan 40 is installed inside the cabinet 10 near the second side plate 12 and is used to drive the air from the air inlet 111, the air inlet surface 21, and the air outlet surface 22 to the air outlet 121. In actual applications, there are multiple fans 40, which are arranged vertically, and the axis of the fans 40 extends along the first direction. In this embodiment, the fan 40 is an exhaust fan.

[0048] See Figure 3-5 and Figure 7-8The humidification component is placed above the water receiving surface 311 and between the air inlet surface 21 and the air inlet 111 of the evaporator 20. It includes a mounting bracket 51, a connector 52, a support 53, and a humidification membrane 54. The mounting bracket 51 extends along a third direction and its two ends are respectively locked to two mounting surfaces 23. The side of the mounting bracket 51 facing away from the air inlet surface 21 is provided with an abutment surface 5131. The connector 52 is detachably fixed to the mounting bracket 51 and is adapted to cooperate with the abutment surface 5131 to form a downward-opening slot 01. The support 53 is fixed to the water receiving tray 30 and is provided with an upward-opening positioning groove 5311 and at least one guide surface 532 extending upwardly from the edge of the positioning groove 5311. The humidification membrane 54 is parallel to the air inlet surface 21. Its bottom end is adapted to be inserted into the positioning groove 5311 through the guide surface 532, and its top end is adapted to abut the abutment surface 5131 and be inserted into the slot (01).

[0049] Specifically, see Figure 7 The mounting bracket 51 is provided with a groove 511 extending in a third direction with its opening facing away from the air inlet surface 21, two connecting portions 512 located at both ends of the groove 511, and an abutment wall 513. The bottom wall of the groove 511 is parallel to the air inlet surface 21 and forms a gap with the air inlet surface 21, thereby avoiding obstructing the air intake of the evaporator 20. Furthermore, the bottom wall of the groove 511 is also provided with a plurality of first air passage holes 5111 arranged in a third direction, thereby further preventing the mounting bracket 51 from blocking the wind. The effective heat exchange area of ​​the evaporator 20 is increased; the connecting part 512 is suitable for locking to the mounting surface 23. When the connecting part 512 is locked to the mounting surface 23, since the mounting surface 23 is located upstream of the air inlet surface 21, it can ensure that a gap is formed between the bottom wall of the groove 511 and the air inlet surface 21; the abutting wall 513 extends downward from the free end of the groove side wall below the groove 511, and the abutting surface 5131 is formed on the abutting wall 513. The structure of the mounting bracket 51 is simple and easy to manufacture and install.

[0050] The connector 52 extends along a third direction and is stepped, and has a first wall 521, a second wall 522, a third wall 523, and a fourth wall 524 connected in sequence. The first wall 521 is suitable for locking with the side wall of the groove above the groove 511. The first wall 521 can be provided with non-removable screws 5211 for easy disassembly and assembly. The second wall 522 corresponds to the groove opening of the groove 511 and has a plurality of second air passage holes 5221 arranged along a third direction. The arrangement of the second air passage holes 5221 avoids reducing the airflow of the evaporator 20, and achieves the fixation of the humidifying film 54 with minimal impact on the evaporator 20 and the humidifying film 54. The third wall 523 and the fourth wall 524 cooperate with the abutment wall 513 to form a slot 01, and the third wall 523 forms the bottom of the slot 01. The connector 52 also has a buffer layer 5231 on the lower surface of the third wall 523, which can prevent damage to the humidifying film 54.

[0051] See Figure 8The support member 53 is a long, open box structure extending in a third direction. It includes a box body 531, several flanges, and a first mounting portion 533. The inner cavity of the box body 531 forms a positioning groove 5311. Each flange extends upwards at an angle relative to the vertical direction from the opening edge of the box body 531, forming a guide surface 532. In this embodiment, the free ends of the three sides of the box body 531 are all connected to flanges, meaning the support member 53 has three guide surfaces 532. The arrangement of multiple guide surfaces 532 is more conducive to… The blind insertion at the bottom of the humidifying membrane 54 has a first mounting part 533 located on the side of the housing 531 away from the air inlet surface 21 and suitable for locking with the water receiving tray 30. Specifically, the first mounting part 533 is locked with the second mounting part 32, which makes it easier to operate. The support member 53 is also provided with several positioning parts 534 arranged along the third direction on the side away from the air inlet surface 21. The positioning parts 534 are suitable for abutting against the groove wall of the receiving groove 31. The setting of the positioning parts 534 avoids the shaking of the support member 53 from damaging the humidifying membrane 54.

[0052] In this embodiment, the support member 53 is suspended above the water-receiving surface 311, and the bottom wall of the positioning groove 5311 is provided with several drainage holes along the third direction, which facilitates water seepage and protects the humidifying membrane 54 from damage.

[0053] An installation channel suitable for the humidifying membrane 54 to enter and exit is formed between the air inlet surface 21 and the first side plate 11. The compressor 60 and the liquid storage tank 70 are placed at the bottom of the cabinet 10. The electrical control box 80 is located above the compressor 60 and the liquid storage tank 70 and is fixed to the front plate 13. The gaps between the compressor 60 and the liquid storage tank 70 and the rear plate 14, and the gaps between the electrical control box 80 and the front plate, form the installation channel. In practice, this makes it easier to install and remove the humidifying membrane 54. The connection between the compressor 60, the liquid storage tank 70, and the evaporator 20 is prior art and will not be described in detail in this embodiment.

[0054] When installing the humidifying membrane 54, remove the first side panel 11 of the cabinet 10, place the humidifying membrane 54 into the cabinet 10 and position it above the positioning groove 5311 along the installation channel. That is, the humidifying membrane 54 is placed into the cabinet 10 along the gap between the electrical control box 80 and the rear panel 14. Then, place the humidifying membrane 54 above the positioning groove 5311 along the gap between the liquid storage tank 70 and the compressor 60 and the rear panel 14. The bottom end of the humidifying membrane 54 can be smoothly inserted into the positioning groove 5311 through the guide surface 532, and the top end of the humidifying membrane 54 abuts against the abutment surface 5131. Then, attach the connector 52 close to the top end of the humidifying membrane 54 and fix it to the mounting bracket 51. The top end of the humidifying membrane 54 is inserted into the slot 01, and the installation is completed.

[0055] When maintenance of the humidifying membrane 54 is required, remove the first side panel 11 of the cabinet 10, remove the connector 52 from the mounting bracket 51, mainly remove and clean the non-removable screws 5211 of the connector 52, then pull the humidifying membrane 54 upward until the bottom end of the humidifying membrane 54 comes out of the positioning groove 5311, then move the humidifying membrane 54 along the gap between the liquid storage tank 70 and the compressor 60 and the rear panel 14 to the side of the cabinet 10 near the first side panel 11, then pull the humidifying membrane 54 upward and remove it along the gap between the electrical control box 80 and the rear panel 14, and the humidifying membrane 54 can be removed from the side where the first side panel 11 is located along the installation channel, then replace the humidifying membrane 54 with a new one and install it in the same way as described above.

[0056] In use, the fan 40 drives air to flow from the air inlet 111, the humidifying membrane 54, the air inlet surface 21, and the air outlet surface 22 to the air outlet 121. Since the humidifying membrane 54 is located on the air inlet side of the evaporator 20, the airflow temperature on the air inlet side is higher. The water in the humidifying membrane 54 can be evaporated by the evaporator 20 and become water vapor, flowing to the air outlet 121, thereby improving the steam humidification efficiency. Therefore, by adopting this technical solution, the positioning groove 5311 can not only position and support the humidifying membrane 54, but also realize the humidifying membrane 54's... 4. The bottom blind insertion allows the humidifying membrane 54 to be basically positioned after insertion by abutting the contact surface 5131. The connecting piece 52 then restricts the upper and lower ends and other directions of the humidifying membrane 54. Thus, during installation or disassembly, only the first side panel 11 of the cabinet 10 needs to be removed, eliminating the need to disassemble the side and front panels of the cabinet 10 as in existing technologies. This makes maintenance more convenient, especially during installation, as the bottom of the humidifying membrane 54 can automatically fall into the positioning groove 5311 under gravity, without the need for separate installation. The installation of an observation window or removal of the front panel is convenient and effortless. Since the air inlet surface 21 and air outlet surface 22 of the evaporator 20 are arranged along a second direction, which is inclined relative to the first direction, and the humidifying film 54 is parallel to the air inlet surface 21, both the evaporator 20 and the humidifying film 54 are placed at an angle within the cabinet 10. The humidifying film 54 is placed on the air inlet side of the inclined evaporator 20. Compared to placing it above the compressor with the evaporator and humidifying film perpendicular to the airflow direction, this arrangement allows for easier installation of the evaporator 20 and humidifying film 54. The larger space allows for a larger volume of the humidifying membrane 54 and evaporator 20. The compressor only needs to provide an installation channel for the humidifying membrane, thus enabling the convenient placement of the large-capacity humidifying membrane 54 in a smaller space. The connector 52 can also apply a certain pressure to the humidifying membrane 54 to ensure water seepage. The drip tray 30 can simultaneously receive the condensate from the evaporator 20 and the seepage from the humidifying membrane 54. The ingenious structure has fewer pipes and ensures the stable operation of the internal components of the air conditioner.
