As shown in fig. 1 and 2, the data center apparatus 10 may include a machine room 20 and a refrigeration system.
The refrigeration system may include an outdoor unit 31 and an indoor unit.
The indoor unit in the embodiment of the present application refers to a module that needs to be placed inside the machine room 20 in the refrigeration system, and since there are many situations in the placement form of the indoor unit, no identification is given to the indoor unit in fig. 1 and 2. The outdoor unit 31 in the embodiment of the present application refers to a module of the refrigeration system that needs to be placed outside the machine room 20. The indoor unit includes a plurality of modules, and the outdoor unit 31 includes one or more modules. It should be noted that the refrigeration system may include one or more indoor units, and may also include one or more outdoor units 31, and the number of the indoor units and the outdoor units 31 is not limited in this embodiment of the application. The outdoor unit 31 may include a condenser, an outdoor fan, a receiver tank, and the like. The indoor unit and the outdoor unit may be connected, for example, by pipes.
The machine room 20 comprises at least one cabinet 21 (7 cabinets are schematically shown in fig. 2). The cabinet position in the embodiment of the present application refers to an area for placing equipment. The cabinet locations in the machine room 20 are generally arranged in a matrix. In the embodiment of the present application, the size of any one cabinet position in the machine room 20 is not limited, and under the condition that the machine room 20 includes a plurality of cabinet positions, the sizes of any two cabinet positions may be equal or unequal, and the cabinet positions may be divided according to actual requirements.
The cabinet locations in the machine room 20 may be used for placing loads. In the embodiment of the present application, a load includes an IT device, and a cabinet for placing the load is referred to as a load device cabinet, and since the load is referred to as the IT device in the embodiment of the present application, the load device cabinet is referred to as the IT device cabinet in the embodiment of the present application, and in other application scenarios, the load may also include other devices, and the load device cabinet may also have other names, and the embodiment of the present application is not limited.
The cabinet locations in the machine room 20 may also be used to place modules, load distribution modules, etc. in the indoor units of the refrigeration system.
In order to more clearly introduce the beneficial effects brought by the solution provided by the embodiment of the present application, a schematic diagram of a possible arrangement scenario inside a machine room is exemplarily shown in fig. 3. As shown in fig. 3, the machine room includes 10 cabinets. The two cabinet positions are used for placing two column head cabinets, and load power distribution modules can be arranged in the column head cabinets. 4 cabinet positions are used for placing 4 row-level air conditioners of the whole cabinet. A full cabinet row level air conditioner may include all of the modules of an indoor unit. The rest 14 cabinets are used for placing IT equipment cabinets. IT can be seen from the layout in fig. 3 that 6 cabinet positions need to be separated from the data center machine room for placing the load power distribution module and the row-level air conditioner, so that more space is occupied in the machine room, and the cabinet outlet rate of the IT equipment in the machine room is lower.
Based on this, the embodiment of the application provides a cabinet, this cabinet is the cabinet that places the load distribution module, can also be provided with some modules in the indoor set of refrigerating system in this cabinet.
Because partial modules and load power distribution modules in the indoor unit in the refrigeration system are integrated in one cabinet in the scheme provided by the application, the space occupied by the indoor unit of the refrigeration system in the machine room can be reduced, so that the space for placing IT equipment in the machine room can be increased, and the cabinet outlet rate of the IT equipment in the machine room is improved.
Fig. 4 schematically illustrates a cabinet 40 provided in an embodiment of the present application. As shown in fig. 4, the cabinet 40 may include a cabinet body.
The cabinet 40 may also include one or more first refrigeration modules 32 disposed within the cabinet body, as well as a power distribution module 41. The first refrigeration module comprises a part of modules in an indoor unit of the refrigeration system. The power distribution modules 41 may include load power distribution modules.
Because the first refrigeration module 32 is integrated in the cabinet in which the power distribution module 41 is placed, the space occupied by the indoor unit of the refrigeration system in the machine room of the data center device can be reduced, so that the space for placing the load in the machine room of the data center can be increased, and the cabinet outlet rate of the load in the machine room can be increased.
In this embodiment, the load distribution module may include a load switch module, and the load distribution module may be connected to a load, and in an on state of the load switch module, the load distribution module may transmit the received power to the load so as to supply power to the load. When the load switch module is in the off state, the load power distribution module stops transmitting the received power to the load.
In the embodiment of the present application, the modules in the indoor unit(s) of the refrigeration system may be divided into a first refrigeration module and a second refrigeration module. The first refrigeration module may include at least one of the one or more indoor units. The second refrigeration module may include at least one of the one or more indoor units. In a possible embodiment, the first and second refrigeration modules can be two parts of a plurality of modules of one or more indoor units.
For example, the first refrigeration module 32 may include a compressor 321. Because the compressor occupation space is more, consequently with the compressor integration in the rack of placing load distribution module, can reduce the space that refrigerating system's indoor set took in data center device's computer lab to the space that is used for placing the load in data center's the computer lab can be increased, thereby the rate of getting out of cabinet of load in the computer lab is improved.
It should be noted that, in the embodiment of the present application, the first refrigeration module 32 may include a module in one indoor unit, or may include modules in a plurality of indoor units. For example, the first refrigeration module 32 may include one or more compressors, and may also include a higher capacity compressor that may be coupled to one or more second refrigeration modules.
As another example, the first refrigeration module 32 also includes a control module 322. The control module is used for controlling the refrigerating system. Therefore, the space occupied by the indoor unit of the refrigerating system in the machine room of the data center device can be further reduced, so that the space for placing the load in the machine room of the data center can be increased, and the cabinet outlet rate of the load in the machine room is improved.
In the embodiment, when the cabinet 40 is installed in the data center device and the refrigeration system is installed, the first refrigeration module 32 in the cabinet 40 can be connected to the outdoor unit of the refrigeration system (for example, connected through pipes (liquid pipes and/or air pipes)). The first refrigeration module 32 located within the cabinet 40 may also be connected to a second refrigeration module.
In this embodiment, the second refrigeration module is disposed in the machine room 20 and outside the cabinet body of the cabinet. Therefore, the modules which need to be placed outside the cabinet in the indoor unit of the refrigerating system can be placed outside the cabinet, and the purpose of cooling the load in the machine room through the refrigerating system is achieved. It is worth noting that the first refrigeration module 32 in the cabinet need not be connected to the second refrigeration module before the refrigeration system is not successfully installed, and the first refrigeration module should not be considered to necessarily be in a connected relationship with the second refrigeration module. For example, the second refrigeration module includes a fan and an evaporator. So, refrigerating system's second refrigeration module can blow to the computer lab to reach the purpose for the load cooling in the computer lab.
In the embodiment of the present application, the arrangement form of the second refrigeration module includes one of the following: a half cabinet row level air conditioning version, a backplane air conditioning version, an overhead air conditioning version, or a bottom air conditioning version. Because partial modules of the indoor unit of the refrigeration system are integrated in the cabinet provided with the load power distribution module, the number of the modules which need to be placed outside the cabinet in the indoor unit of the refrigeration system is small, and the indoor unit can be deployed in a large number of forms. And after the second refrigeration module is deployed in a back plate air conditioning mode, an overhead air conditioning mode or a bottom air conditioning mode, the space in the machine room can be further saved, so that the space for placing the load in the machine room of the data center is further increased, and the cabinet outlet rate of the load in the machine room is improved.
In the embodiment of the present application, other modules may be integrated into the cabinet 40, such as a UPS module 42 included in the cabinet body, and the UPS module 42 may be connected to the load, such as through a load distribution module. In this way, a relatively stable voltage can be provided to the load through the UPS module, and the load can also continue to be powered in the event of a power outage.
The UPS modules 42 may include a UPS power distribution module, a UPS power module, a bypass module, and a UPS control module. One or more (e.g., 4) UPS power modules may be included in the cabinet 40.
The UPS power distribution module can comprise input and output of the UPS and a maintenance bypass power distribution switch, and the UPS power distribution module can be used for input and output of UPS power distribution. The UPS power module may include a rectifier (PFC) and an inverter. The UPS power module may stabilize the BUS voltage after Alternating Current (AC)/Direct Current (DC) or DC/DC conversion of the main and battery inputs, and then convert the BUS voltage into a sine wave output via an inverter (DC/AC). The bypass module may be used for UPS power module failure or maintenance. The UPS control module can be used for controlling the working mode and the state detection of the UPS.
The power distribution module 41 in the embodiment of the present application may further include other modules. For example, the power distribution module 41 may also include a refrigeration system power distribution module that interfaces with a refrigeration system. The refrigeration system power distribution module in this application can include the refrigeration system switch module, and under this refrigeration system switch module was in the on-state, the refrigeration system power distribution module can transmit the electric energy that receives to refrigeration system to supply power for refrigeration system. When the refrigeration system switch module is in the closed state, the refrigeration system power distribution module stops transmitting the received electric energy to the refrigeration system.
As another example, the power distribution module 41 may also include a main input power distribution module. The main input power distribution module may comprise a main input switch module, which may be considered as a connection module of mains power to the cabinet.
The main input power distribution module can be connected with the refrigeration system power distribution module, and when the main input switch module is in an open state, the main input switch module can transmit the received electric energy to the refrigeration system power distribution module.
The main input power distribution module may be further connected to the UPS module, and when the main input switch module is in an on state, the main input switch module may transmit the received power to the UPS module to supply power to the UPS module. The master input power distribution module may also be coupled to the load power distribution module, such as by being coupled to the load power distribution module via the UPS module, to provide power to the load power distribution module via the UPS module. The UPS module, the load power distribution module, the refrigeration system power distribution module, and the refrigeration system in the embodiments of the present application may also be referred to as power modules.
In a possible implementation manner, in the embodiment of the present application, a miniaturized plastic casing switch (for example, a copper bar is discharged after a copper bar is changed from an upper copper bar and a lower copper bar) may be adopted for the main input power distribution module and the UPS power distribution module, so that an effect of not additionally enlarging the external size of the cabinet may be achieved. That is, although the first cooling module is integrated in the cabinet 40 in the embodiment of the present application, the size of the cabinet in the embodiment of the present application is not increased by integrating the first cooling module and the control module. In one possible example, the width of the cabinet 40 in the embodiment of the present application may be 600 mm, the length may be 1200 mm, and the height may be 2000 mm.
It should be noted that the layout of each module in the cabinet 40 shown in fig. 4 is a possible deployment manner, and in practical applications, the position of each module in the cabinet 40 may be flexibly adjusted, for example, the control module 322 may be placed at the back of the cabinet 40.
Fig. 5 exemplarily shows a schematic view of a possible arrangement scenario inside a machine room, and as shown in fig. 5, the machine room includes 10 cabinet locations, which are a cabinet location 211, a cabinet location 212, a cabinet location 213, a cabinet location 214, a cabinet location 215, a cabinet location 216, a cabinet location 217, a cabinet location 218, a cabinet location 219, a cabinet location 220, a cabinet location 221, a cabinet location 222, a cabinet location 223, a cabinet location 224, a cabinet location 225, a cabinet location 226, a cabinet location 227, a cabinet location 228, a cabinet location 229, and a cabinet location 230.
The cabinet positions 211 and 221 in the machine room may be used for placing two cabinets 40.
As the first refrigeration module 32 in the indoor unit in the refrigeration system is integrated in the cabinet 40. The second refrigeration module 33 can therefore be a half-cabinet air conditioner, so that the second refrigeration module 33 in the indoor unit of the refrigeration system can occupy fewer cabinet spaces.
Such as shown in fig. 5, 4 second refrigeration modules 33 may be placed through the cabinet locations 214 and 224, and 2 first refrigeration modules 32 may be placed in one cabinet 40. Therefore, the cabinet positions occupied by the indoor units of the power distribution module, the UPS module and the refrigeration system can be reduced to 4. As shown in fig. 5, the remaining 16 cabinets are used to house IT equipment cabinets. Therefore, the space in the machine room occupied by the indoor unit of the refrigerating system can be reduced by the scheme provided by the embodiment of the application, so that the cabinet outlet rate of the IT equipment cabinet can be improved.
It should be noted that fig. 5 illustrates an example of placing one first refrigeration module 32 in the cabinet 40, in practical applications, one or more first refrigeration modules 32 may be placed in one cabinet 40 of fig. 5, or one first refrigeration module 32 with a stronger capacity may be placed, and the one first refrigeration module 32 may be connected to two second refrigeration modules 33.
Fig. 6 schematically illustrates another possible arrangement scenario of the inside of a machine room provided by the embodiment of the present application, as shown in fig. 6, the inside of the machine room includes two cabinets 40, and the first refrigeration module 32 in the indoor unit in the refrigeration system is integrated in the cabinet 40. Fig. 6 is similar to fig. 5, and differs from fig. 5 in that the form of the second refrigeration module in the indoor unit of the refrigeration system in fig. 6 is a back panel air conditioning form, an overhead air conditioning form, or a bottom air conditioning form. In this way, the indoor units of the refrigeration system may occupy fewer cabinet locations, such as 2 cabinet locations occupied by the power distribution module, the UPS module, and the indoor units of the refrigeration system, as shown in fig. 6. As shown in fig. 6, the remaining 18 cabinets are used to house IT equipment cabinets. Therefore, the space in the machine room occupied by the indoor unit of the refrigerating system can be reduced by the scheme provided by the embodiment of the application, so that the cabinet outlet rate of the IT equipment cabinet can be improved.
