Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an inter-row air conditioner. Background Art

[0002] With the rapid development of communication technology, there is an increasing demand for computer rooms for various data centers. The computer room air conditioning system is the key to computer room design, which mainly plays the role of cooling the heat of various equipment and maintaining the constant temperature of the computer room. In data computer rooms, micro-module data centers are increasingly used due to their advantages such as quick assembly and energy saving and high efficiency. Micro-module data centers often use inter-row air conditioning structures, which are also called inter-row cooling units. They are precision cooling systems specifically designed for high heat density racks and are generally used in data center micro-modules as dedicated air conditioners for computer rooms.

[0003] Because the interior of the row air conditioner is small and contains fan system, refrigeration system, compressor system, electronic control system, humidification system, electric heating components, etc., the design and placement of each component are very complicated and inconvenient, which also causes difficulties in the early production of the unit and the later maintenance and repair. At the same time, due to the influence of the internal space of the air conditioner, the evaporator is difficult to make larger, which reduces the overall performance of the unit. The design and installation position of the evaporator will affect the placement of the compressor system, electronic control system and humidification system, and will also affect the connection between the compressor system pipes and the evaporator.

[0004] For example, in the Chinese invention patent with publication number CN111132519A, a row-to-row air conditioner structure is disclosed. The V-shaped evaporator of the row-to-row air conditioner is inverted, and the V-shaped structure is formed by splicing plate-type evaporators. Therefore, the V-shaped evaporator has multiple rows of gas collecting pipes and liquid dispensing pipes, and the pipeline components are numerous and complex. In addition, the electric control box, compressor, oil separator, etc. in the patent are concentrated on the back of the V side. The space at this position is small, which is not conducive to the flexible arrangement of the electric control box on the one hand, and increases the length of the connecting pipe between the compressor and oil separator pipeline components and the gas collecting pipe assembly and liquid dispensing pipe assembly of the evaporator on the other hand, resulting in more complex winding of the pipeline components and higher copper pipe costs. Therefore, the reasonable selection of the structure of the evaporator and the installation position of the evaporator will affect the overall structure of the unit. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present application is to provide an inter-row air conditioner that can reasonably set the evaporator, shorten the connecting pipe distance between the evaporator and the compressor, and simplify the pipe structure.

[0024] In traditional row-to-row air conditioners, the V-shaped evaporator is installed in a straight-on manner, that is, the inner side of the V is the leeward side. The wet film humidifier is installed on the right side of the windward side of the V-shaped evaporator, while the compressor and oil separator are installed at the lower end of the windward side of the V-shaped evaporator. Because the gas collecting pipe and liquid dispensing pipe of the evaporator are on the side away from its back, this design and installation method will cause the compressor and oil separator to require longer pipes to connect with the gas collecting pipe assembly and liquid dispensing pipe assembly of the evaporator, and the pipes will also be surrounded. In addition, the space on the windward side is limited. After the compressor and oil separator and other components are installed, the distance between the components will be very close, which brings many inconveniences to the installation and maintenance of the unit. In addition, because there is ample space on the leeward side of the V-shaped evaporator, but other components are not installed, the space on the leeward side is wasted. The electric control box is installed at the upper end of the windward side of the V-shaped evaporator. Because the space on the windward side is small, the installation and maintenance of the electric control box is restricted, which is not conducive to the flexible arrangement of the electric control box. In order to solve the above problems, this application is specially proposed.

[0025] See also Figures 1 to 3 As shown, according to an embodiment of the present application, the row air conditioner includes an evaporator 1 and a compressor 2, the evaporator 1 is a V-shaped heat exchanger, the inner side of the V-shaped groove of the evaporator 1 is the windward side, and the compressor 2 is installed on the windward side of the V-shaped groove.

[0026] The inter-row air conditioner installs the compressor 2 on the windward side of the V-groove of the evaporator 1, that is, the side where the V-groove is located. Therefore, the advantage of ample space on the side where the V-groove is located can be used to facilitate the installation and fixation of the compressor 2, making the space utilization of the inter-row air conditioner more reasonable. Since the compressor 2 is installed on the side where the V-groove is located, the connecting pipeline distance of the pipeline components between the gas collecting pipe assembly and the liquid distributing pipe assembly of the evaporator 1 and the compressor 2 can be shortened, the pipeline structure is simplified, the connection between the evaporator 1 and the compressor 2 is more convenient, and it brings convenience to installation and maintenance.

[0027] The inter-row air conditioner further comprises an oil separator 3, which is mounted on the windward side of the V-shaped groove. The inter-row air conditioner further comprises an electric control box 4, which is mounted on the windward side of the V-shaped groove.

[0028] In the inter-row air conditioner of this embodiment, the space on the windward side of the V-shaped groove of the evaporator 1 is sufficient, so that the compressor 2, oil separator 3 and other components can be fully placed in the windward side of the evaporator 1, and the components will not be too compact, so that the space in the windward side is fully utilized. In addition, the pipe parts of the compressor 2 and the oil separator 3 are close to the gas collecting pipe assembly and the liquid dispensing pipe assembly of the evaporator 1, and the pipe parts do not need to be wrapped around to connect with the gas collecting pipe assembly and the liquid dispensing pipe assembly of the evaporator 1, which shortens the connection pipe distance between the evaporator gas collecting pipe assembly and the liquid dispensing pipe assembly and the pipe parts of the compressor 2 and the oil separator 3, making the connection more convenient, making the space utilization of the entire inter-row air conditioner more reasonable, bringing convenience to installation and maintenance, and at the same time making the airflow direction more reasonable without increasing wind resistance.

[0029] The windward side of the V-shaped groove is divided into two parts, the upper and lower parts, the compressor 2 is installed in the lower part of the windward side of the V-shaped groove, and the electric control box 4 is installed in the upper part of the windward side of the V-shaped groove. In the present application, the windward side of the V-shaped groove is divided into two parts, the upper and lower parts, so that the compressor 2 and the oil separator 3 are centrally arranged in the lower part of the windward side of the V-shaped groove, and the electric control box 4 is arranged in the upper part of the windward side of the V-shaped groove, so that the compressor 2, the oil separator 3 and the electric control box 4 can be reasonably arranged, so that the space on the windward side of the V-shaped groove can be more fully utilized, and at the same time, the electric control box 4 can be set independently of other components, which is convenient for the arrangement of the electric control box 4 and improves the heat dissipation performance of the electric control box 4.

[0030] A support beam 5 is provided at the opening of the V-shaped groove of the evaporator 1, and the support beam 5 is connected from one side of the V-shaped groove to the other side, and the electric control box 4 is rotatably mounted on the support beam 5 through a rotating shaft 6. One end of the support beam 5 is connected to the top of one side wall of the V-shaped groove, and the other end is connected to the top of the other side wall of the V-shaped groove, thereby forming a support structure perpendicular to the placement direction of the evaporator 1, which can facilitate the installation and fixation of the electric control box 4. In this embodiment, the evaporator 1 is placed vertically, and the support beam 5 is placed horizontally.

[0031] In one embodiment, the electric control box 4 is installed in the middle of the support beam 5, and a limiter is provided between the rotating shaft 6 and the support beam 5, and the limiter can limit the relative position of the electric control box 4 and the support beam 5. In the installation layout of the electric control box 4, there is a vertical rotating shaft 6 in the middle of the electric control box 4, and the top and bottom of the rotating shaft 6 are fastened by the support beam 5 respectively. The two ends of the support beam 5 are respectively provided with reinforcing beams, one end of the reinforcing beam is fixed to the column of the installation frame 9, and the other end of the reinforcing beam is fixed to the support beam 5 by bolt fasteners. This fixing structure can make the electric control box more firmly fixed inside the unit without shaking. In order to solve the problem that the fixed installation of the electric control box makes the later maintenance and overhaul of the unit difficult, the electric control box designed this time is a rotating structure. This application adopts a vertical intermediate shaft rotation fixed structure. When repairing, the limiter is removed, and the electric control box 4 is rotated around the rotation axis 6 by an angle, so that the electric control box 4 can face the windward side of the V-shaped groove, so that the cover of the electric control box 4 is away from the V-shaped groove of the evaporator 1, and can face the outside where the operator is located, so that there can be a larger operating space, so that other parts can be maintained and overhauled more conveniently and flexibly. When the electric control box 4 is placed on the symmetric axis of the evaporator 1, it can be limited by the limiter, so that the return air is divided into two, so that the evaporator 1 has uniform air intake.

[0032] In one embodiment, the limiting member includes a fixing pin, and a first limiting hole and a second limiting hole are provided on the support beam 5 on which the rotating shaft 6 is installed, and a pin hole is provided on the rotating shaft 6. When the first limiting hole is aligned with the pin hole, the electric control box 4 is parallel to the support beam 5, and when the second limiting hole is aligned with the pin hole, the electric control box 4 is perpendicular to the support beam 5, and the fixing pin can be inserted into the pin hole through the first limiting hole or the second limiting hole. When the electric control box 4 is required to be parallel to the support beam 5, the rotating shaft 6 can be operated to align the first limiting hole with the pin hole, and then the pin shaft is inserted into the first limiting hole and the pin hole, so that the electric control box 4 is kept in a position parallel to the support beam 5. When the electric control box 4 is required to be perpendicular to the support beam 5, the rotating shaft 6 can be operated to align the second limiting hole with the pin hole, and then the pin shaft is inserted into the second limiting hole and the pin hole, so that the electric control box 4 is kept in a position perpendicular to the support beam 5.

[0033] A water receiving pan 7 is provided at the bottom of the inter-row air conditioner, and the evaporator 1 is arranged above the water receiving pan 7, which can ensure that the condensed water on the evaporator 1 can be effectively collected by the water receiving pan 7 to prevent the condensed water from spilling on the ground and polluting the environment.

[0034] A humidifier is provided in the area between the electric control box 4 and the evaporator 1 .

[0035] In one embodiment, the humidifier is a wet film humidifier 8, which extends along the length direction of the evaporator 1. A folding structure is provided at the bottom of the wet film humidifier 8, and the wet film humidifier 8 is fixedly mounted on the water receiving tray 7 through the folding structure.

[0036] In the row air conditioner of the embodiment of the present application, the wet film humidifier 8 is fixed on the symmetry axis on the windward side of the evaporator 1. When the indoor air passes through the wet film humidifier 8, the evaporation temperature on the air inlet side is higher than the evaporation temperature on the air outlet side, which accelerates the evaporation of water in the wet film humidifier 8 into water vapor. Therefore, the air inlet side of the wet film humidifier 8 is set to a long rectangle as much as possible to ensure that the air inlet side of the wet film humidifier 8 quickly and evenly intakes air.

[0037] The lower end of the humidifier has a folded edge structure with bolt holes on the folded edge. The lower end of the wet film humidifier 8 is fixed to the folded edge of the water receiving tray 7 by bolt fasteners.

[0038] The row air conditioner further comprises a base 13 and a mounting frame 9. The mounting frame 9 is mounted on the base 13. The water receiving tray 7 is also mounted on the base 13. Both sides of the evaporator 1 are fixedly connected to the columns 12 of the mounting frame 9 through connecting plates.

[0039] The row air conditioner also includes a windshield, a cover 17, a side panel 10, a front door panel 16, a rear door panel 15, a filter 14, a display panel 20, an electric heater 19, a fan 18, etc., wherein the front panel is covered with ventilation holes to facilitate the in and out of indoor air outlet and indoor return air. The side panels 10 are fixed to the left and right sides of the base 13 respectively, and their front and rear ends are fixed to the front door panel 16, the rear door panel 15 and the windshield by bolt fasteners respectively, and then the top cover covers the left and right side panels 10 and is fixed to the left and right side panels 10. The column 12 on the left is fixed to the side panel 10 on the left, and the column 12 on the right is fixed to the side panel 10 on the right. The column 12 is an angle steel sheet metal part, and there are corresponding fixing holes and matching holes on the two folded edges of the column 12. The compressor 2 and the oil separator 3 are installed on the base 13 and fastened by the compressor fixing bolts. The fan 18 is, for example, a cross-flow fan or a centrifugal fan.

[0040] The windshield is arranged on the leeward side of the evaporator 1. The windshield has folding structures on all four sides, and bolt holes are provided on the folding edges. The windshield is fastened to the base 13, the cover plate 17, the left column 12 plate and the right column 12 plate of the inter-row air conditioner through bolt fasteners. An electric heater 19 is placed in the middle position of the front side of the windshield. The two ends of the electric heater 19 are fixed by brackets respectively. At the same time, a mounting plate is placed at the lower end of the bracket. One end of the mounting plate is fixed on the windshield. This structure allows the electric heater 19 to be more securely fixed in the middle position. In terms of air treatment, the inter-row air conditioner is equipped with a filter 14 on the windward side of its rear door panel 15. The size is the same as that of the rear door panel 15. The filter 14 can effectively filter out impurities, dust and moisture in the air, making the air cleaner and meeting the user's requirements for air comfort. The filter 14 is, for example, a coarse filter.

[0041] The row-to-row air conditioner further includes side panels 10 arranged on both sides of the evaporator 1 . The side panels 10 include upper and lower parts, which are detachably connected via a crossbeam 11 .

[0042] As for the design of the side panel 10, the left and right side panels 10 of the inter-row air conditioner both adopt a segmented structure, that is, they are divided into an upper and lower part, which are detachably connected and fastened by a cross beam 11 in the middle. The inter-row air conditioner can be maintained and inspected in upper and lower sections. When a part of the parts needs to be maintained, it is only necessary to remove the panel corresponding to the part, and there is no need to remove the entire panel, which facilitates maintenance and inspection.

[0043] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.
