Description

Technical Field

[0001] The present application relates to the field of air conditioning technology, and in particular to refrigeration systems and data centers. Background Art

[0002] As information technology advances across various industries, the amount of data that needs to be processed is increasing, and the requirements for data processing speed and capacity are also becoming increasingly stringent. Data centers have emerged as a result. Data centers centrally house a large number of servers to process relevant data. Because servers generate large amounts of heat and are centrally located in data centers, failure to effectively and timely dissipate heat can lead to overheating of the servers, potentially damaging them.

[0003] Because servers have high air quality requirements, existing data center cooling systems typically use internal circulation to prevent contamination from outside air entering the data center. However, these systems suffer from high delivery granularity and difficulty in achieving flexible capacity expansion. Summary of the Invention

[0004] The embodiments of the present application disclose a refrigeration system and a data center, which are used to solve the problems of large delivery granularity and difficulty in achieving elastic expansion in the later stage in the data center.

[0005] In a first aspect, the present application provides a refrigeration system, the system comprising a first exhaust device, a second exhaust device, a first refrigeration device, and a second refrigeration device, wherein the first exhaust device and the second exhaust device are respectively arranged at a first end and a second end of a machine room, the first refrigeration device is close to the first exhaust device, the second refrigeration device is close to the second exhaust device, a first cabinet group is arranged between the first refrigeration device and the second refrigeration device, and a second cabinet group is arranged on a side of the second refrigeration device facing away from the first cabinet group, wherein:

[0006] The first exhaust device is used to draw air outside the machine room into the machine room and transmit it to the first refrigeration device;

[0007] The first refrigeration device is configured to cool the air to generate cold air, wherein the cold air generated by the first refrigeration device is converted into hot air after heat exchange with the first cabinet group;

[0008] The second refrigeration device is used to cool the hot air converted by the first cabinet group to generate cold air, and the cold air generated by the second refrigeration device is converted into hot air after heat exchange with the second cabinet group;

[0009] The second exhaust device is used to discharge the hot air converted by the second cabinet group to the outside of the computer room.

[0010] It can be seen that the refrigeration system provided by the present application introduces air from outside the computer room into the computer room through the first exhaust device. After the air from outside the computer room is drawn into the computer room, it flows unidirectionally between the first refrigeration device, the first cabinet group, the second refrigeration device, and the second cabinet group. Then, the second exhaust device discharges the hot air converted by the second cabinet group to the outside of the computer room, thereby achieving the purpose of dissipating heat for the first cabinet group and the second cabinet group in the computer room, thereby meeting the heat dissipation requirements of the data center. It can also be seen that the refrigeration system provided by the present application introduces air from outside the computer room into the computer room through the first exhaust device. Moreover, after the air flows through the first refrigeration device, the first cabinet group, the second refrigeration device, and the second cabinet group, it is discharged to the outside of the computer room by the second exhaust device. It does not rely on the internal circulation refrigeration method to meet the heat dissipation requirements of the data center, thus breaking the dependence of the data center on the internal circulation refrigeration system in the prior art. Therefore, there is no need to build a complete, closed computer room in advance. In addition, the setting method of one cabinet group corresponding to one refrigeration device means that when users actually deploy the data center, they do not need to consider the selection of refrigeration devices based on the future capacity of the data center. They only need to add a corresponding refrigeration device when adding a cabinet group. The delivery granularity of the data center can be reduced to one cabinet group and one refrigeration device. The delivery granularity is very small, and capacity expansion is very convenient. It can truly achieve on-demand delivery and effectively avoid idle investment.

[0011] In a possible implementation, the system further includes a filtering device, which is disposed between the first exhaust device and the first refrigeration device, and is configured to filter pollutants from the air outside the machine room.

[0012] The filter device filters pollutants from the air outside the computer room, preventing pollutants from entering the data center and contaminating the servers in the data center, thereby meeting the data center's air cleanliness requirements.

[0013] In a possible implementation, the system further includes a windshield device, which is arranged at the third end and the fourth end of the computer room and is close to the first exhaust device, the first refrigeration device, the first cabinet group, the second refrigeration device, the second cabinet group, and the second exhaust device.

[0014] The wind shielding device is used to prevent the wind generated by the first refrigeration device, the first cabinet group, the second refrigeration device and the second cabinet group from being discharged toward the third end and the fourth end of the computer room.

[0015] The wind shielding device blocks the wind generated by the first refrigeration device, the first cabinet group, the second refrigeration device and the second cabinet group from being discharged to the third end and the fourth end of the computer room, which can more efficiently utilize energy and also reduce the degree of air flow turbulence inside the data center computer room.

[0016] In a possible implementation, when the first exhaust device and the second exhaust device are in a closed state, the system further includes a return air device, wherein the return air device is used to recover the hot air converted by the second cabinet group and transmit it to the first refrigeration device.

[0017] It can be seen that the refrigeration system provided by the present application can not only rely on the unidirectional flow of air outside the computer room in the data center to meet the heat dissipation needs of the data center, but can also meet the heat dissipation needs of the data center in an internal circulation refrigeration manner. Unlike the refrigeration system of the data center in the prior art, which can only rely on the circulation of air inside the computer room of the data center to meet the heat dissipation needs of the data center, the refrigeration system provided by the embodiment of the present application is highly flexible.

[0018] In a possible implementation, the first refrigeration device includes a first cooling unit and a first supplementary cooling unit connected by a first pipe, wherein a flowing cooling medium is provided inside the first pipe.

[0019] The first cooling unit is used to cool the air inside the machine room to generate the cold wind, and the temperature of the cooling medium inside the first pipe increases during the cooling process;

[0020] The first supplementary cooling unit is used to cool the cooling medium with increased temperature in the first pipeline outside the machine room.

[0021] In a possible implementation, the system further includes a first water pump, and the first water pump is used to drive the cooling medium inside the first pipe to circulate.

[0022] In a possible implementation, the first cooling portion is formed by bending the first pipe portion.

[0023] In a possible implementation, the second refrigeration device includes a second cooling unit and a second supplementary cooling unit connected by a second pipe, and a flowing cooling medium is provided inside the second pipe.

[0024] The second cooling unit is used to cool the air inside the machine room to generate the cold wind, and the temperature of the cooling medium inside the second pipe increases during the cooling process;

[0025] The second cooling supplement unit is used to cool the cooling medium with increased temperature in the second pipeline outside the machine room.

[0026] In a possible implementation, the system further includes a second water pump, where the second water pump is configured to drive the cooling medium in the second pipe to circulate.

[0027] In a possible implementation, the second cooling portion is formed by bending the second pipe portion.

[0028] In a possible implementation, the first cabinet group includes a plurality of first cabinets arranged side by side, and the second cabinet group includes a plurality of second cabinets arranged side by side.

[0029] In a second aspect, the present application provides a data center, comprising the refrigeration system described in any one of the first aspects. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0045] Data centers contain numerous devices, such as servers, which generate significant amounts of heat during operation. To ensure the safe and efficient operation of these servers, heat dissipation must be managed. Because servers have specific air quality requirements, it's crucial to minimize the entry of outside air into the data center, which can contaminate the servers and reduce their lifespan.

[0046] Currently, existing data center cooling systems (such as traditional data centers or containerized data centers using standard computer rooms) typically utilize internal circulation cooling to meet data center cooling requirements. Internal circulation cooling eliminates the need to introduce external air into the data center room, instead utilizing only internal air for cooling.

[0047] The following combination Figure 1 The schematic top view of a data center in the prior art is shown, and a refrigeration system using an internal circulation refrigeration method in the prior art is introduced in more detail.

[0048] like Figure 1 As shown, a conventional data center includes air conditioning equipment 101 installed at both ends of the computer room, cabinets 102 installed between the air conditioning equipment 101 at both ends of the computer room, a raised floor 103, a plenum box 104 and a return air device 105 installed below the raised floor 103, etc. The air conditioning equipment 101 and cabinets 102 are all installed on the raised floor 103, and the return air device 104 is usually installed at the top of the computer room, near the air conditioning equipment 101. The air conditioning equipment 101, the raised floor 103, the plenum box 104, and the return air device 105 together constitute the cooling system of the conventional data center.

[0049] In this refrigeration system, the air-conditioning equipment 101 usually adopts a special air-conditioning for a chilled water underwater air supply room (hereinafter referred to as the down-supply air-conditioning equipment), which is used to cool the hot air converted by the cabinet 102 to generate cold air. The air-conditioning equipment 101 discharges the cold air generated by itself to a static pressure box 104 arranged under the raised movable floor 103 through its own down-supply outlet, and then the static pressure box 104 discharges the cold air to the cold aisle facing the cabinet 102 through the floor air supply outlet arranged on the raised movable floor. The cold air in the cold aisle is sucked into the cabinet 102 and converted into hot air after heat exchange with the cabinet 102. The hot air converted by the cabinet 102 is discharged to the hot aisle facing the back of the cabinet 102 and is recovered by the return air device 105 and transmitted to the air-conditioning equipment 101 by the return air device 105. The air-conditioning equipment 101 cools the hot air converted by the cabinet 102 again to generate cold air and then transmits it to the static pressure box 104, and then transmits it to the cabinet 102 by the static pressure box 104, and repeats the above cycle.

[0050] It can be seen that the above cooling system can meet the heat dissipation needs of the data center by simply relying on the air inside the data center room to circulate and cool the room.

[0051] However, the above-mentioned refrigeration system adopts an internal circulation refrigeration method, which requires the construction of a complete and closed data center room in advance to prevent outside air from entering the data center and polluting the servers. In other words, even if the data center may only have a small number of cabinets 102 installed and enabled in the initial stage of actual operation, it is still necessary to build a complete and closed data center room in advance, which makes it impossible to reduce the delivery granularity, resulting in idle investment. In addition, the air-conditioning equipment 101 used in the above-mentioned refrigeration system is a large downflow air-conditioning equipment, which is arranged at both ends of the data center room to provide cooling for all cabinets 102 in the data center. Therefore, when deploying, it is necessary to consider the power and quantity of the selected air-conditioning equipment 101 based on the future capacity of the data center (such as the total number of cabinets 102 to be set up in the data center in the future and the size of the total power, etc.). Once the power and quantity of the air-conditioning equipment 101 are selected, it will be difficult to change them later, and it is difficult to achieve elastic expansion.

[0052] In order to solve the problems of large delivery granularity and difficulty in achieving elastic expansion in data centers in the prior art, the present application provides a cooling system and a data center.

[0053] See Figure 2 , Figure 2 This is a top view of a first data center provided in an embodiment of the present application. The data center includes a refrigeration system 100 provided in an embodiment of the present application. Figure 2 The cooling system 100 and the data center provided in the embodiments of the present application are described.

[0054] like Figure 2As shown, the refrigeration system 100 includes: a first exhaust device 130, a second exhaust device 140, a first refrigeration device 110 and a second refrigeration device 120. The data center provided in the embodiment of the present application includes: the above-mentioned refrigeration system 100 and a cabinet group 200, wherein the cabinet group 200 includes: a first cabinet group 210 and a second cabinet group 220.

[0055] from Figure 2 It can be seen that the first exhaust device 130 and the second exhaust device 140 are respectively arranged at the first end and the second end of the machine room, the first refrigeration device 110 is close to the first exhaust device 130, the second refrigeration device 120 is close to the second exhaust device 140, a first cabinet group 210 is arranged between the first refrigeration device 110 and the second refrigeration device 120, and a second cabinet group 220 is arranged between the second refrigeration device 120 and the second exhaust device 140.

[0056] The first exhaust device 130 is used to draw air outside the computer room into the computer room and transmit it to the first refrigeration device 110 .

[0057] The first refrigeration device 110 is used to cool the air to generate cold air. The cold air generated by the first refrigeration device 110 is converted into hot air after heat exchange with the first cabinet group 210.

[0058] The second refrigeration device 120 is used to cool the hot air converted by the first cabinet group 210 to generate cold air, wherein the cold air generated by the second refrigeration device 120 is converted into hot air after heat exchange with the second cabinet group 220.

[0059] The second exhaust device 140 is used to exhaust the hot air converted by the second cabinet group 220 to the outside of the computer room.

[0060] It can be seen that the embodiment of the present application provides Figure 2 The refrigeration system 100 configured in the manner shown introduces air from outside the computer room into the computer room through the first exhaust device 130. The air from outside the computer room is cooled by the first refrigeration device 110 to generate cold air, which is then converted into hot air through heat exchange with the first cabinet group 210. The hot air converted by the first cabinet group 210 is cooled by the second refrigeration device 120 to generate cold air. The cold air generated by the second refrigeration device 120 is converted into hot air through heat exchange with the second cabinet group 220. Then, the hot air converted by the second cabinet group 220 is discharged to the outside of the computer room through the second exhaust device 140. During the heat exchange process between the first cabinet group 210 and the second cabinet group 220 and the cold air, the cold air carries away the heat generated by the first cabinet group 210 and the second cabinet group 220, thereby achieving the purpose of dissipating heat for the first cabinet group 210 and the second cabinet group 220, and meeting the heat dissipation requirements of the data center.

[0061] It can also be seen that the embodiments of the present application provide Figure 2 The refrigeration system 100 configured in the manner shown introduces air from outside the computer room into the computer room through the first exhaust device 130. After the air flows through the first refrigeration device 110, the first cabinet group 210, the second refrigeration device 120, and the second cabinet group 220, it is discharged to the outside of the computer room by the second exhaust device 140. Unlike the refrigeration system of the data center in the prior art, which relies on the internal circulation refrigeration method to meet the heat dissipation needs of the data center, the refrigeration system 100 of the data center in the prior art is broken. Therefore, the refrigeration system 100 provided in the embodiment of the present application does not require the construction of a complete, closed data center computer room in advance.

[0062] It can also be seen that the embodiments of the present application provide Figure 2 In the refrigeration system 100 configured in the manner shown, after air from outside the computer room is introduced into the computer room through the first exhaust device 130, the air flows in a one-way manner inside the computer room. That is, the air from outside the computer room is drawn into the computer room through the first exhaust device 130 arranged at the first end of the computer room, and then the air flows through the first refrigeration device 110, the first cabinet group 210, the second refrigeration device 120, the second cabinet group 220, and finally is discharged outside the computer room through the second exhaust device 140 arranged at the second end of the computer room. Therefore, in a specific implementation, if it is necessary to expand the capacity of the data center provided in the embodiment of the present application, a third refrigeration device, a third cabinet group, a fourth refrigeration device, a fourth cabinet group,…, an nth refrigeration device, an nth cabinet group, the second cabinet group 220 is arranged between the second refrigeration device 120 and the third refrigeration device, the third cabinet group is arranged between the third refrigeration device and the fourth refrigeration device,…, the n-1th cabinet group is arranged between the n-1th refrigeration device and the nth refrigeration device, the nth cabinet group is arranged between the nth refrigeration device and the second exhaust device 140, and n is a natural number greater than 2.

[0063] Take n as 3 for example, Figure 3 As shown, Figure 3 This is a top view of another data center provided in an embodiment of the present application. It can be seen that Figure 3 and Figure 2 The only difference is the third refrigeration device 150 and the third cabinet group 230. For the sake of simplicity, only the third cabinet group 230 is introduced here. Figure 3 and Figure 2 Different places, Figure 3 and Figure 2 The same places can be referenced Figure 2 And related descriptions will not be elaborated here.

[0064] from Figure 3It can be seen that the refrigeration system 100 includes, in addition to the first exhaust device 130, the first refrigeration device 110, the second refrigeration device 120, and the second exhaust device 140, a third refrigeration device 150. The third refrigeration device 150 is close to the second exhaust device 140, and a third cabinet group 230 is provided between the third refrigeration device 150 and the second exhaust device 140.

[0065] The third refrigeration device 150 is used to cool the hot air converted by the second cabinet group 220 to generate cold air, wherein the cold air generated by the third refrigeration device 150 is converted into hot air after heat exchange with the third cabinet group 230.

[0066] The second exhaust device 140 is used to exhaust the hot air converted by the third cabinet group 230 to the outside of the computer room.

[0067] It should be noted that Figure 3 In the example given, n being 3 is only an example. In practical applications, n can be any natural number greater than 2, such as 4, 7, 15, 34, etc., and is not specifically limited here.

[0068] It can be seen that the embodiment of the present application provides Figure 3 In the refrigeration system 100 set up in the manner shown, one cabinet group corresponds to one refrigeration device, such as the first cabinet group 210 corresponds to the first refrigeration device 110, the second cabinet group 220 corresponds to the second refrigeration device 120, and the third cabinet group 230 corresponds to the third refrigeration device 150. When users actually deploy the refrigeration system of the data center, they do not need to consider the selected refrigeration device based on the future capacity of the data center. They only need to add a corresponding refrigeration device when adding a cabinet group. This reduces the delivery granularity of the data center to one cabinet group and one refrigeration device. The delivery granularity is very small, and capacity expansion is very convenient. It can truly achieve on-demand delivery and effectively avoid idle investment.

[0069] It can also be seen that the embodiments of the present application provide Figure 3The refrigeration system 100 configured in the manner shown can transmit the cold air generated by the first refrigeration device 110 to the first cabinet group 210, the cold air generated by the second refrigeration device 120 to the second cabinet group 220, and the cold air generated by the third refrigeration device 150 to the third cabinet group 230. It can also enable the second refrigeration device 120 to refrigerate the hot air converted by the first cabinet group 210 to generate cold air, the third refrigeration device 150 to refrigerate the hot air converted by the second cabinet group 220 to generate cold air, and the second exhaust device 140 to discharge the hot air converted by the third cabinet group 230 to the outside of the computer room. Unlike the refrigeration system of the data center in the prior art, even if only a small number of cabinets 102 may be put into use in the initial stage of actual operation, the air-conditioning equipment 101 installed at both ends of the computer room will still perform cooling with the power of all cabinets 102 that will be installed in the future. Therefore, the embodiment of the present application provides a method of refrigerating the hot air converted by the third cabinet group 230 to the outside of the computer room. Figure 3 The refrigeration system 100 arranged in the manner shown can utilize energy more efficiently.

[0070] In a specific embodiment of the present application, the refrigeration system 100 provided in the embodiment of the present application may further include a filter device 160 and / or a wind shield device 170, such as Figure 4 As shown, the refrigeration system 100 includes a filter device 160 and a wind shield device 170. It can be seen that Figure 4 and Figure 2 The only difference is the filter device 160 and the windshield device 170. For the sake of simplicity, only the filter device 160 and the windshield device 170 are introduced here. Figure 4 and Figure 2 Different places, Figure 4 and Figure 2 The same places can be referenced Figure 2 And related descriptions will not be elaborated here.

[0071] from Figure 4 It can be seen that the filter device 160 is disposed between the first exhaust device 130 and the first refrigeration device 110 .

[0072] The filter device 160 is used to filter pollutants from the air outside the machine room drawn into by the first exhaust device 130 , and transmit the filtered air to the first refrigeration device 110 .

[0073] It can be seen that the embodiment of the present application provides Figure 4 The refrigeration system 100 configured in the manner shown can prevent pollutants from entering the data center through the filtering device 160 and causing pollution to the servers in the data center, thereby meeting the data center's requirements for air cleanliness.

[0074] In a specific embodiment of the present application, the refrigeration system 100 provided in the embodiment of the present application may further include a wind shielding device 170, such as Figure 5 As shown, for convenience, Figure 5 In FIG, only the windshield 170 is shown by the thick black solid line. Figure 5 and Figure 2 The only difference is the windshield 170. For the sake of simplicity, only the windshield 170 is introduced here. Figure 5 and Figure 2 Different places, Figure 5 and Figure 2 The same places can be referenced Figure 2 And related descriptions will not be elaborated here.

[0075] from Figure 5 It can be seen that the wind shield 170 is arranged at the third end and the fourth end of the machine room, and is close to the first exhaust device 130, the first refrigeration device 110, the first cabinet group 210, the second refrigeration device 120, the second cabinet group 220 and the second exhaust device 140.

[0076] The wind shield 170 is used to block the wind generated by the first refrigeration device 110, the first cabinet group 210, the second refrigeration device 120 and the second cabinet group 220 from being discharged toward the third and fourth ends of the computer room, thereby reducing the degree of airflow turbulence inside the computer room.

[0077] by Figure 5 Arranging the wind shield device 170 in the manner shown can also ensure that the cold air generated by the first refrigeration device 110 is more received by the first cabinet group 210 and heat exchanged, that the hot air converted by the first cabinet group is more received by the second refrigeration device 120 and cooled to generate cold air, that the cold air generated by the second refrigeration device 120 is more received by the second cabinet group 220 and heat exchanged, and that the hot air converted by the second cabinet group 220 is discharged outside the computer room through the second exhaust device 140.

[0078] In a specific implementation, the wind shielding device 170 can be a wall of the machine room or a wind shield, which is not specifically limited here.

[0079] It can be seen that the embodiment of the present application provides Figure 5 The refrigeration system 100 configured in the manner shown can utilize energy more efficiently by providing the wind shield 170 , and can also reduce the degree of airflow turbulence inside the data center room.

[0080] It is understood that the embodiments of the present application provide Figures 2 to 5In the refrigeration system 100 configured as shown in any of the accompanying drawings, if the first exhaust device 130 is to draw air from outside the computer room into the computer room and transmit it to the first refrigeration device 110, the first exhaust device 130 needs to be in the open state, and if the second exhaust device 140 is to discharge the hot air converted by the second cabinet group 220 to the outside of the computer room, the second exhaust device 140 also needs to be in the open state.

[0081] In a specific embodiment of the present application, the refrigeration system 100 provided in the embodiment of the present application may further include a return air device 180, such as Figure 6 As shown. It can be seen that Figure 6 and Figure 2 The only difference is the return air device 180. For the sake of simplicity, only Figure 6 and Figure 2 Different places, Figure 6 and Figure 2 The same places can be referenced Figure 2 And related descriptions will not be elaborated here.

[0082] The air return device 180 is used to recover the hot air converted by the second cabinet group 220 and transmit it to the first refrigeration device 110 when both the first exhaust device 130 and the second exhaust device 140 are in a closed state.

[0083] When both the first exhaust device 130 and the second exhaust device 140 are in a closed state, the first refrigeration device 110 is used to cool the hot air transmitted by the recovery device 180 to generate cold air, wherein the cold air generated by the first refrigeration device 110 is converted into hot air after heat exchange with the first cabinet group 210.

[0084] When both the first exhaust device 130 and the second exhaust device 140 are in a closed state, the second refrigeration device 120 is used to cool the hot air converted by the first cabinet group 210 to generate cold air, wherein the cold air generated by the second refrigeration device 120 is converted into hot air after heat exchange with the second cabinet group 220.

[0085] In a specific implementation, the return air device 180 can be a return air fan, etc., which can be set at a position close to the second cabinet group 220, so that the hot air converted by the second cabinet group 220 can be recovered nearby, or it can be set at a position close to the first refrigeration device 110, so that the recovered hot air converted by the second cabinet group 220 can be transmitted nearby to the first refrigeration device 110, so that energy can be used more efficiently.

[0086] It can be seen that the embodiment of the present application provides Figure 6The refrigeration system 100 configured in the manner shown can rely on the unidirectional flow of air outside the computer room between the first exhaust device 130, the first refrigeration device 110, the first cabinet group 210, the second refrigeration device 120, the second cabinet group 220, and the second exhaust device 140 when both the first exhaust device 130 and the second exhaust device 140 are in the open state and the return air device 180 is in the closed state, thereby meeting the heat dissipation requirements of the data center. When the first exhaust device 130 and the second exhaust device 140 are both in the closed state and the return air device 180 is in the open state, the air inside the computer room can circulate between the return air device 180, the first refrigeration device 110, the first cabinet group 210, the second refrigeration device 120, and the second cabinet group 220, thereby meeting the heat dissipation requirements of the data center. Unlike the refrigeration system of the data center in the prior art, which can only rely on the circulation of air inside the data center computer room to meet the heat dissipation requirements of the data center, the refrigeration system 100 provided in the embodiment of the present application has high flexibility.

[0087] In a specific embodiment of the present application, the first cabinet group 210 includes a plurality of first cabinets arranged side by side, and the second cabinet group 220 includes a plurality of second cabinets arranged side by side.

[0088] The first cabinet group 210 includes multiple first cabinets arranged side by side. It can be understood that the first cabinet group 210 includes a row of cabinets consisting of multiple first cabinets. It can also be understood that the first cabinet group 210 includes multiple rows of cabinets consisting of multiple first cabinets.

[0098] It should be noted that Figure 7A and Figure 7B The number and number of rows of first cabinets included in the first cabinet group 210 and the number and number of rows of second cabinets included in the second cabinet group 220 shown are merely examples.

The second cabinet group 220 may include fewer or more second cabinets, and the number of rows of cabinets included in the second cabinet group 220 may be fewer or more. No specific limitations are given here.

Figure 8 As shown, for convenience, Figure 8 In FIG, only the windshield D1, windshield D2, windshield D3 and windshield D4 are represented by thick black solid lines. Figure 8 and Figure 7B The only difference is the wind shielding device in the first cabinet group 210 and the second cabinet group 220. For the sake of simplicity, only the wind shielding device is introduced here. Figure 8 and Figure 7B Different places, Figure 8 and Figure 7B The same places can be referenced Figure 7B And related descriptions will not be elaborated here.

[0100] from Figure 8 It can be seen that a windshield D1 is provided between the first row of cabinets 210A and the second row of cabinets 210B in the first cabinet group 210, and a windshield D2 is provided between the second row of cabinets 210B and the second row of cabinets 210C.

[0101] The wind shield D1 is used to allow the first row of cabinets 210A and the second row of cabinets 210B to receive more cold air generated by the first refrigeration device 110 for heat exchange, and to prevent the cold air generated by the first refrigeration device 110 from being discharged to the second refrigeration device 120 and being received by the second refrigeration device 120, thereby making more efficient use of energy.

The wind shield device D2 can also prevent the hot air converted by the second row of cabinets 210B and the second row of cabinets 210C from being discharged to the first refrigeration device 110 and mixing with the cold air discharged from the first refrigeration device 110, causing airflow turbulence.

[0103] The wind shielding device D3 is used to allow the first row of cabinets 220A and the second row of cabinets 220B to receive more cold air generated by the second refrigeration device 220 for heat exchange, and to prevent the cold air generated by the second refrigeration device 220 from being discharged to the second exhaust device 140 and then discharged outside the computer room by the second exhaust device 140, thereby making more efficient use of energy.

[0104] The wind shield device D4 is used to discharge more of the hot air converted by the second row of cabinets 220B and the third row of cabinets 220C to the second exhaust device 140, and is discharged outside the computer room by the second exhaust device 140, which can more effectively utilize energy. The wind shield device D4 can also prevent the hot air converted by the second row of cabinets 220B and the third row of cabinets 220C from being discharged to the second refrigeration device 120 and mixing with the cold air discharged from the second refrigeration device 120, causing airflow turbulence.

[0105] It can be seen that the refrigeration system 100 provided in the embodiment of the present application and arranged in the manner shown in Figure 8 can more efficiently utilize energy by arranging wind shields D1 and D2 in the first cabinet group 210, and wind shields D3 and D4 in the second cabinet group 220, while also reducing the degree of air flow turbulence inside the data center computer room.

[0106] It should be noted that Figure 8The arrangement of the windshield devices in the first cabinet group 210 and the second cabinet group 220 shown is merely an example. In actual applications, the windshield devices may be arranged according to actual conditions, and no specific limitation is given here.

The first supplementary cooling section 112 can also be a standalone chiller or a combination of a chiller and a cooling tower, without specific limitation here. The cooling medium flowing within the first pipe 113 can be cold water or a refrigerant, without specific limitation here.

[0112] In a specific implementation, the second cooling unit 121 can be a heat exchange coil formed by bending a portion of the second pipe 123, and the second supplementary cooling unit 122 can also be a heat exchange coil formed by bending a portion of the second pipe 123. The second supplementary cooling unit 122 can also be a combination of a heat exchange coil formed by bending a portion of the second pipe 123 and a device such as a fan, a sprinkler, or a chiller. It can also be a standalone chiller or a combination of a chiller and a cooling tower, without specific limitations here. The flowing cooling medium provided within the second pipe 123 can be cold water or a refrigerant, etc., without specific limitations here.

[0113] It should be noted that, in a specific implementation, the first cooling unit 111 and the second cooling unit 121 are usually arranged inside the machine room, and the first supplementary cooling unit 112 and the second supplementary cooling unit 122 are usually arranged outside the machine room. Figure 9 In the figure, the first cooling section 111 and the second cooling section 121 are framed by solid lines, indicating that the first cooling section 111 and the second cooling section 121 are arranged inside the machine room, and the first supplementary cooling section 112 and the second supplementary cooling section 122 are framed by dotted lines, indicating that the first supplementary cooling section 112 and the second supplementary cooling section 122 are arranged outside the machine room.

[0114] In a specific implementation, the first water pump 190A can be set inside or outside the machine room, and the second water pump 190B can be set inside or outside the machine room, which is not specifically limited here. Figure 9 In FIG, the first water pump 190A and the second water pump 190B are framed by solid lines, indicating that the first water pump 190A and the second water pump 190B are arranged inside the machine room.

[0115] In a specific implementation, the data center provided in the embodiment of the present application may be a container-type data center, which includes a container-type refrigeration system 110A. Figure 11 The containerized refrigeration system 110A and the containerized data center provided in the embodiments of the present application are described.

[0116] like Figure 11As shown, the containerized refrigeration system 100A includes: a first exhaust container 130A, a second exhaust container 140A, a first refrigeration container 110A and a second refrigeration container 120A, and the containerized data center includes: the above-mentioned containerized refrigeration system 100A and a containerized cabinet group 200A, wherein the containerized cabinet group 200A includes: a first cabinet group container 210A and a second cabinet group container 220A.

[0117] from Figure 11 It can be seen that the first degassing container 130A and the second degassing container 140A are respectively arranged at the first end and the second end of the data center, the first refrigeration container 110A is close to the first degassing container 130A, the second refrigeration container 120A is close to the second degassing container 140A, the first cabinet group container 210A is arranged between the first refrigeration container 110A and the second refrigeration container 120A, and the second cabinet group container 220A is arranged between the second refrigeration container 120A and the second degassing container 140A.

[0118] The first exhaust container 130A includes a first exhaust device 130 for drawing air outside the data center into the computer room and transmitting the air to the first refrigeration container 110A.

[0119] The first refrigeration container 110A includes a first refrigeration device 110 for cooling air to generate cold air. The cold air generated by the first refrigeration container 110A is converted into hot air after heat exchange with the first cabinet group container 210A.

[0120] The second refrigeration container 120A includes a second refrigeration device 120 for refrigerating the hot air converted by the first rack container 210A to generate cold air. The cold air generated by the second refrigeration container 120A is converted into hot air after heat exchange with the second rack container 220A.

[0121] The second exhaust container 140A includes a second exhaust device 140 for exhausting the hot air converted by the second cabinet group container 220A to the outside of the computer room.

[0122] It can be seen that the embodiment of the present application provides Figure 11The containerized refrigeration system 100A, configured as shown, introduces air from outside the data center into the data center through the first exhaust container 130A. The air outside the data center is cooled by the first refrigeration container 110A to generate cold air, which is then converted into hot air through heat exchange with the first cabinet group container 210A. The hot air converted from the first cabinet group container 210A is then cooled by the second refrigeration container 120A to generate cold air. The cold air generated by the second refrigeration container 120A is then converted into hot air through heat exchange with the second cabinet group container 220A. The hot air converted from the second cabinet group container 220A is then discharged to the outside of the data center through the second exhaust container 140A. During the heat exchange process with the cold air, the first cabinet group container 210A and the second cabinet group container 220A carry away heat generated by the first cabinet group container 210A and the second cabinet group container 220A, thereby dissipating heat from the first cabinet group container 210A and the second cabinet group container 220A, thereby meeting the heat dissipation requirements of the containerized data center.

[0123] It can also be seen that the embodiments of the present application provide Figure 11 The containerized refrigeration system 100A, configured as shown, introduces air from outside the data center into the data center through the first exhaust container 130A. After the air flows through the first refrigeration container 110A, the first cabinet group container 210A, the second refrigeration container 120A, and the second cabinet group container 220A, it is discharged outside the data center through the second exhaust container 140A. Unlike the refrigeration systems of containerized data centers in the prior art that rely on internal circulation refrigeration to meet the heat dissipation needs of containerized data centers, the refrigeration systems of containerized data centers in the prior art have broken the reliance on internal circulation refrigeration in the prior art.

[0124] It can also be seen that the embodiments of the present application provide Figure 11In the containerized refrigeration system 100A configured as shown, after air from outside the data center is introduced into the data center through the first exhaust container 130A, the air flows in a one-way manner within the data center. That is, the air from outside the data center is drawn into the data center through the first exhaust container 130A disposed at the first end of the data center. The air then flows through the first refrigeration container 110A, the first cabinet group container 210A, the second refrigeration container 120A, and the second cabinet group container 220A, and is finally discharged outside the data center through the second exhaust container 140A disposed at the second end of the data center. Therefore, in a specific implementation, if it is necessary to expand the capacity of the container-type data center provided in the embodiment of the present application, a third refrigeration container, a third cabinet group container, a fourth refrigeration container, a fourth cabinet group container, ..., an nth refrigeration container, an nth cabinet group container, the second cabinet group container 220A is arranged between the second refrigeration container 120A and the third refrigeration container, the third cabinet group container is arranged between the third refrigeration container and the fourth refrigeration container, ..., the n-1th cabinet group container is arranged between the n-1th refrigeration container and the nth refrigeration container, and the nth cabinet group container is arranged between the nth refrigeration container and the second exhaust container 140A, where n is a natural number greater than 2.

[0125] It can be seen that the embodiment of the present application provides Figure 11 In the containerized refrigeration system 100A configured in the manner shown, one cabinet group container corresponds to one refrigeration container, for example, the first cabinet group container 210A corresponds to the first refrigeration container 110A, the second cabinet group container 220A corresponds to the second refrigeration container 120A, and the third cabinet group container 230 corresponds to the third refrigeration container 150A. This allows users to deploy the containerized refrigeration system 100A in a containerized data center without having to consider the selected refrigeration container based on the future capacity of the containerized data center. Instead, users only need to add a corresponding refrigeration container when adding a cabinet group container. This reduces the delivery granularity of the containerized data center to one cabinet group container and one refrigeration container. The delivery granularity is very small, capacity expansion is very convenient, and on-demand delivery can be achieved, effectively avoiding idle investment.

[0126] In a specific implementation, the containerized refrigeration system 100A may further include a filter container 160A and a return air container 180A. Figure 12 As shown. It can be seen that Figure 12 and Figure 11 The only difference is the filter container 160A and the return air container 180A. For the sake of simplicity, only the Figure 12 and Figure 11 Different places, Figure 12 and Figure 11 The same places can be referenced Figure 11 And related descriptions will not be elaborated here.

[0127] from Figure 12 It can be seen that the filter container 160A is disposed between the first exhaust container 130A and the first refrigeration container 110A.

[0128] The filter container 160A includes a filter device 160 for filtering pollutants from the air outside the data center drawn into the first exhaust container 130A.

[0129] The return air container 180A includes an air return device 180 for recovering the hot air converted by the second cabinet group container 220A and transmitting the hot air to the first refrigeration container 110A when the first degassing container 130A and the second degassing container 140A are both in a closed state.

[0130] The above description is merely a preferred embodiment of the present application and does not limit the present invention in any form.
