The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0028] In the description of this application, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the appendix.

[0029] It should be understood that in this application, "connection" and "connected" can both refer to a mechanical connection or a physical connection. That is, A and B being connected or A and B being connected can mean that there are fastened components (such as screws, bolts, rivets, etc.) between A and B, or that A and B are in contact with each other and A and B are difficult to separate.

[0030] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0031] In data center server rooms, air conditioning systems play a crucial role in ensuring that the equipment operates stably in a suitable temperature environment. As a commonly used refrigeration device, the proper installation method of multi-split air conditioning outdoor units directly affects the system's operating efficiency, ease of maintenance, and lifespan.

[0032] The installation method of the outdoor unit of the air conditioner in the relevant technology is relatively simple. On the one hand, the outdoor unit is installed on a precast concrete foundation, and the benchmark and height difference of each unit cannot be guaranteed. The layout is relatively messy. There is no reasonable connection and fixing method between multiple outdoor units. This not only occupies too much space, but may also lead to complicated refrigerant piping layout, increase the risk of refrigerant leakage and system resistance, and affect the cooling effect.

[0033] On the other hand, the lack of effective rain protection measures for the outdoor units of air conditioners has caused inconvenience to the maintenance and debugging work of engineering personnel, reduced the efficiency of operation and maintenance, and may even affect the normal operation of the data center computer room due to malfunctions and downtime.

[0034] Therefore, this application provides an air conditioning system in which at least two outdoor air conditioning units are arranged in a coordinated manner, with each outdoor air conditioning unit having the same reference and height difference, resulting in high space utilization, greatly reducing the difficulty of pipe layout, and helping to reduce the risk of refrigerant leakage and system resistance, thereby ensuring the cooling effect of the air conditioning system.

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0036] Combination Figure 1 As shown, this embodiment provides an air conditioning system, which includes at least two outdoor air conditioning units 1 and a support platform 2.

[0037] At least two outdoor air conditioning units 1 are arranged at intervals along a first horizontal direction 00a; the support platform 2 includes at least two metal beams 21, which are arranged in parallel along the first horizontal direction 00a and at least two metal beams 21 are spaced apart along a second horizontal direction 00b, which is perpendicular to the first horizontal direction 00a.

[0038] Each outdoor unit 1 of the air conditioner is located on at least two metal beams 21 and is securely connected to each metal beam 21.

[0039] In this embodiment, the air conditioning system has at least two outdoor air conditioning units 1 arranged at intervals along the first horizontal direction 00a to achieve a unified layout. At least two outdoor air conditioning units 1 are simultaneously installed on at least two metal beams 21 to ensure that the reference and height difference of each outdoor air conditioning unit 1 are consistent, which is conducive to improving the space utilization of the air conditioning system. Moreover, the refrigerant pipes of the outdoor air conditioning units 1 can be arranged in series using the space between the metal beams 21, which greatly reduces the difficulty of pipe arrangement, helps to reduce the risk of refrigerant leakage and system resistance, thereby ensuring the cooling effect of the air conditioning system.

[0040] In some possible implementations, the number of outdoor air conditioning units 1 may be, for example, one, two, three, etc.

[0041] The number of metal beams 21 within the support platform 2, for example, two, three, four, etc.

[0042] For example, the number of metal beams 21 at the bottom of each air conditioner outdoor unit 1 can be two, three, etc.

[0043] In another example, when the number of air conditioner outdoor units 1 is four or more, the four or more air conditioner outdoor units 1 can be arranged in an array, wherein one of the first horizontal direction 00a and the second horizontal direction 00b is the row direction of the array, and the other is the column direction of the array. Simultaneously, the metal beams 21 within the support platform 2 are grouped according to the number of rows or columns, with at least two beams per row or column. Multiple air conditioner outdoor units 1 in the same row, or multiple air conditioner outdoor units 1 in the same column, are installed on the same group of metal beams 21.

[0044] In some possible implementations, the metal beam 21 can be an I-beam, channel steel, angle steel, T-beam, square steel pipe, rectangular steel pipe, etc. All of the above-mentioned similar metal beams 21 can provide a flat support surface and can provide reliable support for the air conditioner outdoor unit 1 at the bottom.

[0045] For example, the metal beam 21 is a high-strength I-beam.

[0046] In some possible implementations, each outdoor unit 1 of the air conditioner is equipped with several piping structures, including refrigerant pipes, electrical wiring, cooling water pipes, etc. The piping structures of each outdoor unit 1 are led out from below and are centrally arranged in the overhead area between at least two metal beams 21.

[0047] In some possible implementations, the air conditioning system is an air conditioning device that combines refrigerant pump technology and multi-split system, which can be used in scenarios requiring year-round cooling, such as data centers and communication equipment rooms. The air conditioning system achieves high efficiency and energy saving by utilizing natural cold sources and working in conjunction with mechanical refrigeration.

[0048] For example, the air conditioning system also includes multiple indoor air conditioning units, each of which is connected to the outdoor air conditioning unit 1 via refrigerant piping. The outdoor air conditioning unit 1 uses components such as a refrigerant pump, compressor, or evaporative condenser to reduce the refrigerant temperature. The low-temperature refrigerant enters the indoor air conditioning unit along the refrigerant piping. The indoor air conditioning unit is located in the computer room of the data center. The air or chilled water piping in the computer room exchanges heat with the low-temperature refrigerant in the indoor air conditioning unit, outputting low-temperature air or low-temperature chilled water, which flows back into the computer room to meet the cooling needs of the air-cooled and water-cooled equipment in the computer room.

[0049] Combination Figure 1 As shown, in some embodiments, the first horizontal direction 00a is parallel to the first side 101 of the outdoor unit 1, the second horizontal direction 00b is parallel to the second side 102 of the outdoor unit 1, and the first side 101 and the second side 102 intersect perpendicularly.

[0050] With the above arrangement, the first side 101 of the air conditioner outdoor unit 1 is parallel to the first horizontal direction 00a, and the second side 102 is parallel to the second horizontal direction 00b. When multiple air conditioner outdoor units 1 are arranged at intervals along the first direction, the installation orientation of the air conditioner outdoor units 1 is consistent. In this way, the layout of multiple air conditioner outdoor units 1 is neat and orderly, which can further improve the space utilization of multiple air conditioner outdoor units 1. The pipe layout direction of multiple air conditioner outdoor units 1 is completely consistent, which can further reduce the difficulty of pipe layout, reduce the risk of refrigerant leakage and system resistance, thereby ensuring the cooling effect of the air conditioning system.

[0051] In addition, the neat and orderly layout of multiple outdoor air conditioning units 1 makes the refrigerant piping route simpler, reduces system resistance, and improves cooling efficiency. At the same time, it facilitates later maintenance and debugging work, and each outdoor air conditioning unit 1 can be controlled individually, reducing the downtime of the entire air conditioning system.

[0052] Combination Figure 1 As shown, in some embodiments, the outdoor unit 1 of the air conditioner is a cuboid, with the first side 101 and the second side 102 being rectangular surfaces, and the area of ​​the first side 101 being larger than that of the second side 102.

[0053] With the above arrangement, multiple air conditioner outdoor units 1 can be arranged at intervals along the length direction. Adjacent air conditioner outdoor units 1 are only opposite each other with their smaller second side 102 facing each other, while the larger first side 101 has a larger space on its outer side. Thus, for the air conditioner outdoor unit 1, since the air inlet of the air conditioner outdoor unit 1 is usually located on the first side 101, the large space left on the outer side of the first side 101 helps to ensure the air intake efficiency of the air conditioner outdoor unit 1 and ensure the cooling effect of the air conditioner outdoor unit 1.

[0054] In some possible implementations, the outdoor unit 1 of the air conditioner includes an air inlet and an air outlet, with the air inlet located on the first side 101 and the air outlet located on the top of the outdoor unit 1.

[0055] For example, the outdoor unit 1 of the air conditioner also includes multiple air outlet fans, which are respectively arranged on the top of the outdoor unit 1 and opposite to the position of the air outlet.

[0056] Combination Figure 1 As shown, in some embodiments, the distance between the two outermost metal beams 21 along the second horizontal direction 00b is D1, and the bottom dimension of the outdoor unit 1 along the second horizontal direction 00b is D2, where D1 = D2.

[0057] With the above arrangement, metal beams 21 are fixedly supported at the edge position of the outdoor unit 1 along the second horizontal direction 00b. The support stability of the outdoor unit 1 is better, and there is a large overhead space between the metal beams 21, which can be used to arrange refrigerant pipes.

[0058] In some other possible implementations, there are two metal beams 21, with a spacing of D1 between the two metal beams 21, and each metal beam 21 is arranged below the two sides of the outdoor unit 1 along the second horizontal direction 00b.

[0059] Combination Figure 1 As shown, in some embodiments, the outdoor unit 1 of the air conditioner includes an electrical control box 11 and a rain shelter assembly 12, which are respectively located on the second side 102, and the rain shelter assembly 12 is sealed to the top edge of the second side 102.

[0060] In this embodiment, the second side 102 where the electrical control box 11 is located in the outdoor unit 1 of the air conditioner has a rain shelter assembly 12. On the one hand, the rain shelter assembly 12 can prevent rainwater from directly corroding the electrical control box 11, accelerating the aging of the components in the electrical control box 11, and easily causing electrical failures in the electrical control box 11. On the other hand, when the staff inspects and maintains the electrical control box 11, the rain shelter assembly 12 can protect the staff from the rain, improving the convenience of the staff's maintenance and debugging work, and thus improving the operation and maintenance efficiency of the outdoor unit 1 of the air conditioner.

[0061] Combination Figure 1 As shown, in some embodiments, when one air conditioner outdoor unit 1 has another air conditioner outdoor unit 1 on the side where the second side 102 is located, the rain shelter assembly 12 on the second side 102 is sealed to the edge of the other air conditioner outdoor unit 1 away from the second side 102.

[0062] In this embodiment, the rain shelter can be arranged between two adjacent air conditioner outdoor units 1 and sealed to each of the two air conditioner outdoor units 1 respectively, so that the staff can stand between the two air conditioner outdoor units 1 to carry out inspection and maintenance.

[0063] Combination Figure 1 As shown, in some embodiments, when there are no other air conditioner outdoor units 1 on the side where the second side 102 of one of the air conditioner outdoor units 1 is located, the rain shelter assembly 12 on the second side 102 is arranged to be tilted downward.

[0064] In this embodiment, for the air conditioner outdoor unit 1 at the head of each row or column, in order to improve the drainage efficiency of the rain shelter assembly 12, the rain shelter assembly 12 is configured to tilt downwards, which can increase the rain-blocking effect on the one hand and improve the drainage efficiency on the other.

[0065] Combination Figure 1 , Figure 2 and Figure 5As shown, in some embodiments, the rain shelter assembly 12 includes a rain shield 121 and at least one diagonal brace 122. The rain shield 121 is sealed to the top edge of the second side surface 102 along one side edge of the first horizontal direction 00a, and the other side edge is away from the second side surface 102. The top end of the at least one diagonal brace 122 is connected to the bottom surface of the rain shield 121, and the bottom end of the at least one diagonal brace 122 extends obliquely and is connected to the second side surface 102.

[0066] With the above arrangement, the rain shelter assembly 12 is composed of a rain shelter plate 121 and a diagonal brace 122, which has a simple structure and is easy to install and disassemble.

[0067] For example, the rain shield 121 is a sheet metal structural component, which has a simple structure and is easy to produce and process.

[0068] In some possible implementations, the rain shield 121 is arranged with its two sides inclined downward along the second direction, thereby improving the drainage efficiency of the top surface of the rain shield 121.

[0069] Among some possible implementations, refer to Figure 5 As shown, the second side 102 of the air conditioner outdoor unit 1 is provided with first vertical frames 14 on both sides along the second direction. The bottom of the diagonal brace 122 is provided with a bent part 1221, which is parallel and attached to the outer side of the first vertical frame 14 and is fastened with screws to realize the connection between the diagonal brace 122 and the second side 102.

[0070] Combination Figure 3 and Figure 4 As shown, in some embodiments, the bottom of the air conditioner outdoor unit 1 is provided with at least two first horizontal frames 13, the at least two first horizontal frames 13 are arranged along the first horizontal direction 00a, each first horizontal frame 13 is located on a metal beam 21 and is fastened to the corresponding metal beam 21 by at least one fastening bolt 3.

[0071] With the above arrangement, the outdoor unit 1 of the air conditioner can be fastened to the top surface of the metal beam 21 by the first horizontal frame 13 at the bottom. The overall support performance of the outdoor unit 1 of the air conditioner is good. Moreover, the first horizontal frame 13 has high structural strength. By fastening the first horizontal frame 13 to the metal beam 21, the safety and stability of the outdoor unit 1 of the air conditioner can be further improved.

[0072] See also some possible implementations. Figure 5 As shown, the bottom surface of the metal beam 21 away from the outdoor unit 1 is provided with several mounting holes 211, and the metal beam 21 can be installed and fixed on the ground using the mounting holes 211.

[0073] Combination Figure 4As shown, in some embodiments, at least one damping pad 4 is provided between the first horizontal frame 13 and the metal beam 21.

[0074] By arranging vibration damping pads 4 between the first horizontal frame 13 and the metal beam 21, the vibration energy of the outdoor unit 1 can be reduced on the one hand, and the deformation capacity of the vibration damping pads 4 can be used to provide pre-tightening force for the fastening connection of the outdoor unit 1, thereby improving the reliability of the connection.

[0075] In some possible implementations, the damping pad 4 includes, but is not limited to, spring washers, rubber pads, etc.

[0076] Combination Figure 4 As shown, in some embodiments, the side of the first horizontal frame 13 is provided with at least one clearance notch 131, and the fastening bolts 3 are respectively located in at least one clearance notch 131.

[0077] In this embodiment, the fastening bolt 3 is built into the clearance notch 131 of the first horizontal frame 13. The fastening bolt 3 can directly connect the first horizontal frame 13 and the horizontal surface of the metal beam 21, which is more reliable. Moreover, the fastening bolt 3 is built-in, and there is no protruding structure outside the first side 101 of the air conditioner outdoor unit 1. The side of the air conditioner outdoor unit 1 is neat and simple, which can reduce the space occupied by the air conditioner outdoor unit 1 outside the first side 101. A maintenance passage can be arranged outside the first side 101. The two sides of the maintenance passage are neat and orderly, which improves the safety and operation and maintenance efficiency of the staff when working in the maintenance passage.
