[0028] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0029] Furthermore, it should be understood that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0030] Figure 1 This is a schematic diagram of the structural composition of the first embodiment 100 of the cooling system described in this disclosure. Figure 1 As shown, it includes: outdoor unit 101 and indoor unit 102.

[0031] Outdoor unit 101 is deployed outdoors in the data center, while indoor unit 102 and the server rack 103 to be cooled are both deployed indoors. Indoor unit 102 is deployed in the air-conditioned area, and server rack 103 is deployed in the computer room area. The air-conditioned area and computer room area are respectively as follows: Figure 1 As shown, the air-conditioned area can refer to Figure 1 The area above the longer horizontal dashed line shown in the diagram can refer to the area below the horizontal dashed line, while the computer room area can refer to the area below the horizontal dashed line.

[0032] In addition, each outdoor unit 101 corresponds to at least one indoor unit 102, and each outdoor unit 101 and its corresponding indoor unit 102 form a unit 104. The outdoor unit 101 in each unit 104 is used to dissipate the heat generated by the corresponding indoor unit 102 to the outside, and the indoor unit 102 in each unit 104 is used to send cool air to the computer room area to provide heat dissipation for the server rack 103.

[0033] To simplify the accompanying drawings, Figure 1 The diagram only shows one unit 104, and it is assumed that the unit 104 includes one outdoor unit 101 and three corresponding indoor units 102.

[0034] As can be seen, the above embodiments propose a deployment scheme for a distributed large phase change cooling system for data centers. Based on the characteristics of distributed systems, the deployment of indoor and outdoor units is unified, achieving a reasonable deployment and cost-effective state, while improving the cooling effect.

[0035] In practical applications, data centers can be multi-layered or single-layered. If they are multi-layered, the deployment methods for each layer can be the same.

[0036] In some embodiments of this disclosure, the indoor unit 102 may include: a wind wall, each wind wall may include at least one air conditioner.

[0037] In other words, indoor unit 102 can refer to an air wall, which can be composed of air conditioners (corresponding indoor unit parts). Each air wall can include at least one air conditioner, which is very simple and convenient to implement. In addition, the number of air conditioners included in different air walls can be the same or different, but generally speaking, the number of air conditioners included in different air walls is the same.

[0038] For example, each air wall may include an air wall frame, multiple air conditioners, and some connecting devices. The air wall frame can be used to support or fix the air conditioners. Multiple air conditioners are combined together in a certain way through the connecting devices to form a solid structure, and provide liquid inlet and outlet, etc., to provide heat dissipation function for the cabinet 103.

[0039] In addition, in some embodiments of this disclosure, the indoor unit 102 can use a parallel flow air supply method to deliver cold air to the computer room area. Experiments show that this method can improve the air supply effect, thereby improving the cooling effect of the cabinet 103, etc.

[0040] Figure 2 This is a schematic diagram of the structural composition of the second embodiment 200 of the cooling system described in this disclosure. Compared to Figure 1 The embodiment shown, Figure 2 The illustrated embodiment further includes a hot air return duct 105 located in the indoor ceiling. Additionally, for the sake of simplicity, [further details are needed]. Figure 2The outdoor unit 101 and the unit 104 are not shown.

[0041] The hot return air passage 105 can be located on a ceiling in the indoor of the data center, and the specific form is not limited.

[0042] As shown in Figure 2 The indoor unit 102 can send cold air to the machine room area in a parallel flow manner, cool the servers in the cabinet 103 using the cold air, and send the hot air generated after cooling back to the air conditioning area through the hot return air passage 105, and so on, so as to realize continuous cooling of the cabinet 103.

[0043] In addition, in some embodiments of the present disclosure, the number of outdoor units 101 can be N+1, N is a positive integer, the number of indoor units 102 can be M, M is a positive integer greater than 1, and M can be L times of N+1, L is a positive integer greater than 1, and each outdoor unit corresponds to L indoor units.

[0044] The specific values of N, M and L can be determined according to actual needs. For example, the value of N can be 3, the value of M can be 12, and the value of L can be 3. In this way, there are 3+1 units, and each unit includes 1 outdoor unit 101 and 3 indoor units 103.

[0045] Correspondingly, since each outdoor unit 101 corresponds to multiple indoor units 102, the deployment difficulty of the outdoor unit 101 can be simplified, and the deployment efficiency is improved.

[0046] In addition, in some embodiments of the present disclosure, the N+1 units can operate in a hot backup mode, which includes that the N+1 units are all started to operate, and in response to any unit failure, the other units without failure continue to operate after increasing the rotating speed.

[0047] Assuming that the value of N is 3, the 4(3+1) units can all be started to operate, and the overall belongs to multiple low-load conditions, and the energy saving performance is good. If one of the units fails, the other 3 units without failure can still operate normally, but the load of the other 3 units without failure is larger, so the rotating speed can be increased to ensure the overall cooling effect.

[0048] Alternatively, in some embodiments of the present disclosure, the N+1 units can operate in a cold backup mode, which includes that N units of the N+1 units are started to operate, and the remaining one unit is a backup unit, and in response to any unit failure, the backup unit is used to replace the failed unit to operate.

[0049] Assuming that the value of N is 3, for 4 units, one of the units can be used as a backup unit, the remaining 3 units are started and need to ensure that the 3 units can cover the entire indoor cooling capacity demand, when one of the 3 units fails, the backup unit can be replaced with the failed unit to run, so that the original refrigeration effect can be maintained, and hot spots can be avoided.

[0050] In some embodiments of the present disclosure, M indoor units 102 can be deployed in parallel and can be numbered 1-M in a predetermined order, which can include a left-to-right order or a right-to-left order. In addition, the L indoor units 102 in the same unit can meet the following requirements: the absolute value of the difference between the numbers of any two indoor units 102 is greater than 1.

[0051] Assuming that the value of M is 12, the value of N is 3, and the value of L is also 3, as a possible implementation, Figure 3 A schematic diagram of the correspondence between the outdoor unit 101 and the indoor unit 102 of the present disclosure is shown.

[0052] As Figure 3 shown, each indoor unit 102 can be deployed in parallel in the air conditioning area and can be approximately uniformly deployed in the space of the air conditioning area. Accordingly, the 12 indoor units 102 can be numbered indoor unit 1, indoor unit 2, indoor unit 3, indoor unit 4, indoor unit 5, indoor unit 6, indoor unit 7, indoor unit 8, indoor unit 9, indoor unit 10, indoor unit 11 and indoor unit 12. In addition, for ease of description, the four outdoor units 101 are numbered outdoor unit a, outdoor unit b, outdoor unit c and outdoor unit d. Then, the outdoor unit a can correspond to the indoor unit 1, the indoor unit 3 and the indoor unit 5, the outdoor unit b can correspond to the indoor unit 2, the indoor unit 4 and the indoor unit 6, the outdoor unit c can correspond to the indoor unit 7, the indoor unit 9 and the indoor unit 11, and the outdoor unit d can correspond to the indoor unit 8, the indoor unit 10 and the indoor unit 12.

[0053] Taking the outdoor unit a as an example, it can be seen that among the three indoor units corresponding to the outdoor unit a, namely the indoor unit 1, the indoor unit 3 and the indoor unit 5, the numbers of any two indoor units are not continuous, i.e. the absolute value of the difference between the numbers of any two indoor units is greater than 1. For example, for the indoor unit 1 and the indoor unit 3, the absolute value of the difference between the numbers is 2, for the indoor unit 3 and the indoor unit 5, the absolute value of the difference between the numbers is also 2, and for the indoor unit 1 and the indoor unit 5, the absolute value of the difference between the numbers is 4, all of which are greater than 1.

[0054] In addition, Figure 3The corresponding relationship shown is only for illustration and does not limit the technical solutions of the present disclosure. Still taking the outdoor unit a as an example, the outdoor unit a can also correspond to the indoor unit 1, the indoor unit 5 and the outdoor unit 9, as long as the absolute value of the difference in the number of any two indoor units is greater than 1.

[0055] Through the above processing, the indoor airflow organization can be uniform, and when a certain unit 104 fails, the impact on the entire indoor is small, and the temperature of a certain area of the cabinet 103 is as much as possible to avoid rapid rise due to no corresponding indoor unit 102 to transmit cold air, and hot spots and the like.

[0056] For example, taking the outdoor unit a shown in Figure 3 as an example, if the outdoor unit a corresponds to three indoor units with consecutive numbers, i.e., the indoor unit 1, the indoor unit 2 and the indoor unit 3, then if the outdoor unit a fails, the cabinet 103 (such as the leftmost cabinet shown in Figure 1 ) in the corresponding area will cause the temperature to rise rapidly due to no cold air being transmitted, and hot spots will occur, but if the processing method described in the present disclosure is used, as shown in Figure 3 , and assuming that the outdoor unit a fails, since the indoor units corresponding to the outdoor unit a and the outdoor unit b are spaced apart, there will still be some cold air (such as from the indoor unit 2 corresponding to the outdoor unit b) transmitted into, thereby delaying the occurrence of hot spots and the like.

[0057] Figure 4 FIG. 4 is a schematic diagram of the constituent structure of a third embodiment 400 of the cooling system according to the present disclosure. Compared with the embodiments shown in Figure 1 and Figure 2 , the embodiment shown in Figure 4 further comprises a constant humidity machine 106. In addition, for simplicity of the drawings, the hot return air passage 105 is not shown in Figure 4 .

[0058] The constant humidity machine 106 can be located indoors in the data center, such as in the air conditioning area, for controlling the relative humidity in the indoor to be within a predetermined range.

[0059] The specific number of the constant humidity machine 106 is not limited and can be determined according to actual needs, and in addition, the specific value of the predetermined range can also be determined according to actual needs.

[0060] By providing the constant humidity machine 106, it is avoided that the humidity in the indoor is too high or too low, thereby improving the operation stability of the devices in the indoor and prolonging the service life and the like.

[0061] The above is an introduction to the system embodiment, and the following further describes the scheme described in the present disclosure through a method embodiment.

[0068] In some embodiments of the present disclosure, the M indoor units can be disposed in parallel and can be numbered 1-M in a predetermined order, and the predetermined order can include a left-to-right order or a right-to-left order. Correspondingly, the L indoor units in the same unit can meet the following requirement: the absolute value of the difference between the numbers of any two indoor units is greater than 1.

[0069] In addition, in some embodiments of the present disclosure, the fault repair processing according to the fault repair mode can include: in response to all N+1 units being started before the fault occurs, the other units without faults are started after the rotating speed is increased, and in response to N units of the N+1 units being started before the fault occurs, the remaining one unit is used as a backup unit to replace the unit with a fault to run.
