Description

Technical Field

[0001] The present invention relates to the technical field of data center cooling, and in particular to a vortex air storage device, an air storage system, a zero-energy data center and a method. Background Art

[0002] Currently, data center cooling methods include room-level cooling, cabinet-level cooling, and modular cooling, as shown below: Room-level cooling refers to the use of room-level dedicated air-conditioning equipment to regulate the temperature and humidity of the entire space of the data center. The basic principle is that the air-conditioning unit not only provides cooling capacity, but also stirs and mixes hot and cold air to achieve a uniform average temperature. However, during the cooling process, the airflow is easily affected by the equipment or structures in the computer room, resulting in uneven temperature distribution in the computer room, large temperature differences in the vertical direction, and easy generation of local hot spots.

[0003] Cabinet-level cooling refers to refrigeration components designed for each cabinet, such as cooling backplanes, cooling cabinets, etc. This type of cooling design has high requirements on the load-bearing capacity and floor height of the data center, the overall pipeline layout is complex, and the construction cost is too high.

[0004] Modular refrigeration refers to the integration of the data center and the refrigeration system into a new type of portable and transportable data center, such as a container-type data center. This refrigeration design occupies the internal space of the container, reducing the utilization rate of the container space, and easily causing uneven air supply, affecting the cooling effect of the cabinet.

[0005] In actual applications, it is found that most of the above three refrigeration and cooling methods require the participation of power equipment, which is not only costly, but also consumes a lot of electricity and cannot effectively achieve energy conservation and emission reduction.

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Combine the following Figure 1-Figure 10 , the vortex wind storage device, wind storage system, zero-energy data center and method provided by the embodiments of the invention are described in detail through specific embodiments and their application scenarios.

[0035] In the first aspect, Figure 1 As shown, an embodiment of the present invention provides a vortex air storage device 1, comprising: an air storage chamber 11 and an air inlet 12 and an air outlet 13 connected to the air storage chamber 11; the air inlet 12 is used to collect natural wind, and the air outlet 13 is used to supply air to a computer room 9 of a zero-energy data center; An air guide 14 is provided in the air storage chamber 11 , and the air guide 14 is used to guide the natural wind to circulate in the air storage chamber 11 in a vortex manner.

[0036] It can be understood that the vortex wind storage device 1 mainly utilizes outdoor wind energy to collect the natural wind that is continuously or intermittently input into the air inlet 12, and uses the air storage chamber 11 to convert the received unstable natural wind into a relatively stable vortex-formed wind supply airflow, and then realizes cooling of the zero-energy data center based on the wind supply airflow.

[0037] To meet actual application needs, zero-energy data centers are built in high wind speed areas (for example, the annual average wind speed is not less than 1.5m / s, and the maximum wind speed in the wind direction is not less than 3.0m / s) and in low-density building areas to form a high-density utilization of the external wind environment.

[0038] The air inlet 12 and the air outlet 13 can be respectively arranged on the peripheral wall of the air storage chamber 11 and communicate with the internal space of the air storage chamber 11; the internal space of the air storage chamber 11 can be configured as a columnar space, and the air guide 14 can be extended along a spiral path and arranged on the inner wall of the columnar space. This design can form a guide air duct extending along a spiral path on the inner wall of the columnar space; the air inlet 12 can be configured to be opposite to one end of the guide air duct, and the air outlet 13 is correspondingly configured to be opposite to the other end of the guide air duct. In this way, when natural wind enters the air storage chamber 11 from the air inlet 12, the guide air duct can guide the natural wind to circulate in the air storage chamber 11 in the form of a vortex, and then output from the air outlet 13.

[0039] Of course, the air guide member 14 may also include a plurality of air guide vanes, which are combined in the air storage chamber 11 to construct an annular or spiral air guide duct in the air storage chamber 11. This design can also guide the natural wind to circulate in the air storage chamber 11 in a vortex manner.

[0040] As can be seen from the above, by arranging the air guide 14 in the air storage chamber 11, natural wind is continuously collected based on the air inlet 12. After the natural wind enters the air storage chamber 11, the air guide 14 guides the natural wind to circulate in the air storage chamber 11 in the form of a vortex. This design converts unstable natural wind into a relatively stable vortex airflow. The vortex airflow gradually accumulates the kinetic energy of the natural wind subsequently received in the form of vortex flow, thereby circulating in the air storage chamber 11. While storing natural wind based on the air storage chamber 11, it also ensures that the airflow can reach the computer room 9 of the zero-energy data center through the air outlet 13, thereby meeting the cooling requirements of the heating equipment in the computer room 9.

[0041] Compared with the existing refrigeration design of the data center using room-level refrigeration, cabinet-level refrigeration or modular refrigeration, the present invention effectively solves the problem of high energy consumption in the existing refrigeration and cooling of the data center. It can use the collected natural wind to provide a stable wind field for the data center. The equipment cost is low and no electricity is consumed. It can achieve refrigeration and cooling of the data center, which is conducive to ensuring the refrigeration effect.

[0042] In some embodiments, Figure 1 As shown, the air storage chamber 11 is cylindrical, and the air inlet 12 and the air outlet 13 are both arranged on the side wall of the air storage chamber 11 along the tangential direction.

[0043] It can be understood that when the air storage chamber 11 is cylindrical, the internal space of the air storage chamber 11 corresponds to a cylindrical space; the air guide member 14 can be configured to be arranged on the inner wall of the air storage chamber 11, and extend along a spiral trajectory relative to the central axis of the air storage chamber 11 to construct a spiral air guide duct on the inner wall of the air storage chamber 11.

[0044] Correspondingly, the air inlet 12 and the air outlet 13 can be configured to extend in the horizontal direction and be arranged on the side wall of the air storage chamber 11 along the tangent direction of the side wall of the air storage chamber 11; wherein, the air inlet 12 can be configured to be arranged on the upper side of the air outlet 13 in the vertical direction.

[0045] Therefore, based on the above-mentioned arrangement design of the air inlet 12 and the air outlet 13, in actual application, natural wind with a relatively low temperature enters the air storage chamber 11 along the tangential direction, and then circulates along the inner wall of the air storage chamber 11 in the direction of the vortex under the guidance of the air guide 14, and gradually descends under the action of its own weight, and finally is output from the air outlet 13 along the tangential direction; this design not only ensures the smoothness of the wind path, but also reduces the along-the-way loss generated during the rotation and transportation of the air supply airflow in a vortex manner.

[0046] In some embodiments, Figure 1 As shown, the vortex air storage device 1 further includes: a spacer 15; the spacer 15 is arranged in the air storage chamber 11 to define a first air chamber 1101 and a second air chamber 1102 arranged side by side in the air storage chamber 11, the first end of the first air chamber 1101 is connected to the first end of the second air chamber 1102, and the second end of the first air chamber 1101 is connected to the second end of the second air chamber 1102; An air guide 14 is provided in the first air chamber 1101 and / or the second air chamber 1102; under the guidance of the air guide 14, the natural wind flows in the first air chamber 1101 and / or the second air chamber 1102 in a vortex manner, and the mainstream direction of the natural wind flows through the first air chamber 1101 and the second air chamber 1102 in sequence, and circulates in this way.

[0047] It can be understood that the air storage chamber 11 includes a first air chamber section, a second air chamber section and a third air chamber section, and the first air chamber section, the second air chamber section and the third air chamber section are connected in sequence from top to bottom; the spacer 15 is arranged in the second air chamber section to separate the second air chamber section into a first air chamber 1101 and a second air chamber 1102 arranged side by side in a horizontal direction, thereby ensuring that the first end of the first air chamber 1101 and the first end of the second air chamber 1102 are connected through the third air chamber section, and the second end of the first air chamber 1101 and the second end of the second air chamber 1102 are connected through the first air chamber section.

[0048] The wind guide member 14 can be arranged in at least one of the first wind chamber 1101 and the second wind chamber 1102. Of course, a part of the wind guide member 14 can also be arranged in the first wind chamber section and the third wind chamber section. This design can ensure that the natural wind flows in the first wind chamber 1101 or the second wind chamber 1102 in a vortex manner, and the first wind chamber 1101, the third wind chamber section, the second wind chamber 1102 and the first wind chamber section are connected in sequence to form a closed-loop fluid passage, ensuring that the mainstream direction of the natural wind circulates along the closed-loop fluid passage.

[0049] It should be pointed out here that multiple first wind chambers 1101 and second wind chambers 1102 can be set. This design can achieve the mainstream direction of natural wind passing through each first wind chamber 1101 in sequence, then passing through each second wind chamber 1102 in sequence, and then returning to the first wind chamber 1101, thereby forming a cycle.

[0050] In some embodiments, Figure 1 As shown, in order to ensure that the natural wind circulates in the air storage chamber 11 in the above-mentioned form, the air guide 14 includes a first spiral section 141, a first transition section 142, a second spiral section 143 and a second transition section 144 connected in sequence; The first spiral section 141 is disposed in the first wind chamber 1101; the first transition section 142 is disposed between the first end of the first wind chamber 1101 and the first end of the second wind chamber 1102; the second spiral section 143 is disposed in the second wind chamber 1102; the second transition section 144 is disposed between the second end of the second wind chamber 1102 and the second end of the second wind chamber 1102; The first spiral section 141 is used to guide the natural wind to flow in the first wind chamber 1101 in the form of a vortex and output it from the first end of the first wind chamber 1101; the first transition section 142 is used to guide the natural wind output from the first end of the first wind chamber 1101 to flow toward the first end of the second wind chamber 1102; the second spiral section 143 is used to guide the natural wind to flow in the second wind chamber 1102 in the form of a vortex and output it from the second end of the second wind chamber 1102; the second transition section 144 is used to guide the natural wind output from the second end of the second wind chamber 1102 to flow toward the second end of the first wind chamber 1101.

[0051] in, Figure 1 Arrows are used to illustrate a schematic diagram of natural wind circulating between the first wind chamber 1101 and the second wind chamber 1102 under the guidance of the wind guide member 14.

[0052] In the second aspect, Figure 2 As shown, an embodiment of the present invention further provides an air storage system, comprising: an air inlet duct 2, an air outlet duct 3, an air volume regulating device and the vortex air storage device 1 as described above; The first end of the air inlet duct 2 is used to collect natural wind, and the second end of the air inlet duct 2 is connected to the air inlet 12 of the vortex air storage device 1; the air outlet 13 of the vortex air storage device 1 is connected to the first end of the air outlet duct 3, and the second end of the air outlet duct 3 is used to be connected to the machine room 9; the air volume regulating device is arranged on the air outlet duct 3 to adjust the air volume to the air outlet duct 3.

[0053] It is understandable that the air storage system can be configured to be located in an air supply control room on one side of the machine room 9, with the first end of the air inlet duct 2 being located on the outer wall of the air supply control room, and the second end of the air outlet duct 3 being located on the wall of the machine room 9, so as to realize air supply into the machine room 9.

[0054] The machine room 9 is usually provided with a heating device, and the air flow entering the machine room 9 dissipates heat from the heating device by convection heat dissipation, so that the air volume regulating device can adjust the ventilation opening of the air outlet duct 3 according to the air demand of the machine room 9 to control the air volume of the air outlet duct 3.

[0055] Since the wind storage system includes a vortex wind storage device 1, and the specific structure of the vortex wind storage device 1 refers to the above embodiment, the wind storage system of this embodiment includes all the technical solutions of the above embodiment, and therefore at least has all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here one by one.

[0056] In some embodiments, Figure 2 As shown, the air volume regulating device comprises: a wind shield 4, a regulating component 5 and a control module 6; The wind shield 4 is movably disposed in the air outlet duct 3, the regulating component 5 is transmission-connected to the wind shield 4; the control module 6 is electrically connected to the regulating component 5; The control module 6 is used to control the regulating component 5 to adjust the opening of the wind shield 4 according to the required air volume in the machine room 9.

[0057] It is understandable that in some examples, the wind shield 4 can be configured to be inserted in the air outlet duct 3 along the horizontal direction, and the regulating component 5 is connected to the wind shield 4 to drive the wind shield 4 to move in the horizontal direction relative to the air outlet duct 3, so as to adjust the opening of the wind shield 4 and achieve the purpose of controlling the air outlet volume of the air outlet duct 3.

[0058] In some examples, the wind shield 4 can also be configured to be rotatably disposed in the air outlet duct 3, and the regulating component 5 is connected to the wind shield 4 to drive the wind shield 4 to rotate relative to the air outlet duct 3, so as to adjust the opening of the wind shield 4 and achieve the purpose of controlling the air output of the air outlet duct 3.

[0059] The regulating component 5 may be a telescopic member, a mechanical arm or other driving mechanism, as long as it can receive control instructions from the control module 6 to control the wind shield 4 to move or rotate quantitatively relative to the air outlet duct 3 .

[0060] Furthermore, the control module 6 is configured to be electrically connected to each heat generating device in the computer room 9. The control module 6 can calculate the required air volume in the computer room 9 based on the operating power of each heat generating device and the total heat generating device of the computer room 9, and then use the specific heat capacity formula to convert the total heat generating device of the computer room 9, thereby controlling the regulating component 5 to adjust the opening of the wind shield 4.

[0061] In some embodiments, Figure 2 As shown, the regulating assembly 5 includes: a bracket 51, a balance rod 52 and a balance water tank 53; the balance rod 52 is rotatably arranged on the bracket 51, the balance water tank 53 is connected to the first end of the balance rod 52, and the second end of the balance rod 52 is transmission-connected to the wind shield 4; the balance water tank 53 is configured to replenish water under the control of the water supply valve K1; The control module 6 is electrically connected to the water supply valve K1 and is used to control the working state of the water supply valve K1 according to the opening degree of the wind shield 4 .

[0062] It is understandable that the bracket 51 and the balance bar 52 constitute a lever well known in the art, the balance bar 52 has a fulcrum, and the bracket 51 is supported on the fulcrum; specifically, the balance bar 52 includes a first balance arm and a second balance arm connected to each other, and the fulcrum is located between the first balance arm and the second balance arm; wherein the first balance arm is used to support the balancing water tank 53, and the second balance arm is used to connect to the wind shield 4.

[0063] A water inlet pipe is provided on the upper side of the balancing water tank 53 , and a water supply valve K1 is installed on the water inlet pipe to control the water inlet pipe to replenish water into the balancing water tank 53 ; wherein, the water supply valve K1 may be an electromagnetic proportional valve.

[0064] After calculating the required opening of the wind shield 4 according to the required air volume in the machine room 9, the control module 6 can convert the target weight of the balancing water tank 53 using the torque balance formula according to the structural characteristics of the lever, and then calculate the water replenishment amount of the balancing water tank 53 according to the difference between the target weight and the current weight of the balancing water tank 53, and then control the opening and opening time of the water supply valve K1 according to the water replenishment amount, so as to achieve the control requirement of the water replenishment amount of the balancing water tank 53.

[0065] Optionally, when the wind shield 4 is inserted into the air outlet duct 3 in the horizontal direction, a distance measuring sensor electrically connected to the control module 6 can be arranged in the air outlet duct 3, and the moving stroke of the wind shield 4 is detected by the distance measuring sensor. The control module 6 can perform more refined control over the opening and opening time of the water supply valve according to the information fed back by the distance measuring sensor, so as to achieve precise control over the opening of the wind shield 4.

[0066] Optionally, an angle sensor may also be provided on the balance bar 52. The angle sensor and the control module 6 are electrically connected to monitor the inclination angle of the balance bar 52 in real time. The control module 6 can calculate the target angle of the balance bar 52 relative to the horizontal plane according to the opening of the wind shield 4, and then control the opening and opening time of the water supply valve according to the angle information fed back by the angle sensor to ensure that the balance bar 52 reaches the target angle. This design can also achieve precise control of the opening of the wind shield 4.

[0067] It should be pointed out here that when controlling the regulating component 5, although the configured battery is used to provide working power to the control module 6, various sensors and the water supply valve, this will consume a certain amount of electrical energy. However, compared with the existing air-conditioning refrigeration method, the effect of this part of the electrical energy is less, and after adjusting the opening of the wind shield 4 once, there is no need to frequently adjust the opening of the wind shield 4 again, so this part of the electrical energy consumption can be ignored.

[0068] In some embodiments, Figure 2 As shown, the regulating component 5 further includes: an elastic member 7 , and the second end of the balancing rod 52 is connected to the wind shielding member 4 via the elastic member 7 .

[0069] It is understandable that the elastic member 7 can be a spring, the second end of the balance bar 52 is connected to one end of the elastic member 7 , and the other end of the elastic member 7 is connected to the wind shield 4 .

[0070] When the elastic member 7 is a spring, multiple springs can be provided, and the multiple springs are arranged side by side to ensure the rigidity of the connection between the balance bar 52 and the wind shield 4, so as to reliably adjust the opening of the wind shield 4.

[0071] By arranging the second end of the balance bar 52 to be connected to the wind shield 4 through the elastic member 7, a flexible connection between the balance bar 52 and the wind shield 4 is ensured, which makes it convenient to use the elastic member 7 to transmit the force from the balance bar 52 to adjust the opening of the wind shield 4, and is also beneficial to ensure that the lever formed by the bracket 51 and the balance bar 52 maintains a better dynamic balance, thereby enhancing the sensitivity of the opening adjustment of the wind shield 4.

[0072] In some embodiments, Figure 2As shown, the distance between the first end of the balance pole 52 and the fulcrum on the balance pole 52 can be set to be greater than the distance between the second end of the balance pole 52 and the fulcrum on the balance pole 52, that is, the length of the first balance arm of the balance pole 52 is greater than the length of the second balance arm. This design only requires a slight change in the weight of the balance water tank 53 to adjust the opening of the wind shield 4 in a large range, so that in the process of regulating the opening of the wind shield 4, it is beneficial to reduce the water replenishment amount of the balance water tank 53, thereby reducing the consumption of water resources.

[0073] In some embodiments, Figure 2 As shown, in order to facilitate the collection of natural wind, the air inlet duct 2 includes a first segment 21 and a second segment 22; a guide air outlet for collecting natural wind is formed at the first end of the first segment 21, and the diameter of the first segment 21 gradually decreases from the first end to the second end; The first end of the second segment 22 is connected to the second end of the first segment 21 , and the second end of the second segment 22 is connected to the air inlet 12 .

[0074] In some embodiments, Figure 2 As shown, the air storage system also includes: a bypass air duct 8; the first end of the bypass air duct 8 is connected to the air inlet duct 2, and the second end of the bypass air duct 8 is connected to the air outlet duct 3; wherein the air volume regulating device is arranged between the second end of the bypass air duct 8 and the second end of the air outlet duct 3.

[0075] It is understandable that since the bypass air duct 8 realizes fluid connectivity between the air inlet duct 2 and the air outlet duct 3, when the speed of the natural wind from the outside is relatively high and is continuously transported into the air inlet duct 2, a part of the natural wind enters the air storage chamber 11 from the air inlet duct 2, and the other part of the natural wind enters the bypass air duct 8. The air storage chamber 11 converts the unstable natural wind received into a relatively stable air supply airflow in the form of a vortex. This part of the air supply airflow is mixed with the natural wind output by the bypass air duct 8, and then enters the computer room 9 of the zero-energy data center under the control of the air volume regulating device.

[0076] When the speed of the external natural wind is relatively low and is intermittently delivered to the air inlet duct 2 in a short period of time, the bypass duct 8 may not deliver natural wind. At this time, the air supply airflow retained in the air storage chamber 11 will be directly output from the air outlet duct 3 and delivered to the computer room 9 of the zero-energy data center according to the set air volume under the control of the air volume regulating device.

[0077] It should be pointed out here that an unpowered one-way valve plate can be arranged in the bypass air duct 8, and the unpowered one-way valve plate can be opened under the action of the wind pressure of the natural wind from one side of the air inlet duct 2, that is, the unpowered one-way valve plate is used to limit the natural wind from flowing from the air inlet duct 2 to the air outlet duct 3; accordingly, when the air storage chamber 11 supplies air alone, the unpowered one-way valve plate is used to prevent the air flow in the air outlet duct 3 from returning to the air inlet duct 2 along the bypass air duct 8.

[0078] In the third aspect, Figure 3 and Figure 4 As shown, the present invention also provides a zero-energy data center, comprising: a machine room 9, an air supply control room and the air storage system as described above; The machine room 9 has a storage space 91 and a vent 92 and an exhaust skylight 93 connected to the storage space 91. The storage space 91 is used to place the heating equipment. The air supply control room is arranged at one side of the machine room 9 , and the air storage system is arranged in the air supply control room. The second end of the air outlet duct 3 in the air storage system is connected to the ventilation port 92 .

[0079] The machine room 9 and the air supply control room can be connected through a switch door, and the ventilation opening 92 is arranged on the wall of the machine room 9 on the side facing the air supply control room.

[0080] Optionally, an air supply control room may be provided on the east side and / or west side of the machine room 9, and at least two air storage systems may be provided in each air supply control room.

[0081] It can be understood that since the zero-energy data center includes the above-mentioned air storage system, and the specific structure of the air storage system refers to the above-mentioned embodiment, the zero-energy data center of this embodiment includes all the technical solutions of the above-mentioned embodiments, and therefore has at least all the beneficial effects achieved by all the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0082] In particular, since the zero-energy data center cools down the heat-generating equipment in the computer room 9 based on the wind energy provided by the wind storage system, this cooling design realizes the effective utilization of outdoor wind energy. Compared with the room-level refrigeration, cabinet-level refrigeration and modular refrigeration used in existing data centers, it has the following beneficial effects: (1) The zero-energy data center no longer uses conventional air-conditioning equipment to cool the computer room 9, and no longer needs to consider the problem of air-conditioning equipment occupying the limited internal space of the computer room 9. It also does not need to configure corresponding power equipment for the air-conditioning equipment, thereby greatly improving the utilization rate of the computer room 9; (2) The energy for cooling in a zero-energy data center comes from outdoor natural cold sources, and no electric energy is consumed. The electric energy only needs to bear the power load of IT equipment, lighting, monitoring and communication functions in the computer room 9. The air conditioning power load is zero, and the PUE value can be reduced to below 1.05; (3) Since the zero-energy data center is not equipped with conventional air-conditioning equipment, its construction cost and operation and maintenance cost are much lower than existing technologies. It is green and energy-saving throughout its life cycle, with a low TCO value, and achieves zero carbon emissions in cooling and temperature reduction in the zero-energy data center.

[0083] When constructing a zero-energy data center, the first thing to do is to integrate and judge the external environment and climate information, as well as conduct a comprehensive analysis of the internal use functions and environmental requirements; based on the comprehensive analysis, the building form is mainly constructed to respond to the external environment and climate conditions, regulate the external wind environment around the zero-energy data center, and shape a form that is beneficial to internal ventilation. Secondly, the internal layout construction takes over the basic framework of the building form and directly responds to the internal functions and their environmental regulation needs.

[0084] The comprehensive analysis of the construction of a zero-energy data center includes three parts: the outside of the data center, the inside of the data center, and other influencing factors. Among them, in the analysis of the outside of the data center, it is necessary to collect the annual monthly temperature, wind meteorological information, surrounding artificial structures and natural environmental elements; in the site selection of the data center, it should be considered to build in a high wind speed and low-density building area to form a high-density utilization of the external wind environment; in the internal analysis of the data center, it is necessary to investigate the owner and user needs, volume scale and functional type to meet the construction of zero-cooling data centers under different computing networks and different computing power requirements. It should be noted that in my country's severely cold and cold areas, due to the fact that the outdoor wind environment itself has the characteristics of low temperature all year round, this technical solution has year-round availability, that is, the area where the zero-energy data center is constructed meets the following conditions: the annual average wind speed is greater than the set wind speed value, the density of the surrounding buildings is lower than the set density value, and the annual average temperature is lower than the set temperature value.

[0085] In some examples, the zero-energy data center can be located in a low-density building area in the suburbs of Hohhot, with the specific latitude and longitude being 40°49'N and 111°41'E. Meteorological conditions: annual average temperature 7.2℃; The average outdoor wind speed in summer is 1.8 m / s, and the most common wind direction in summer is C SW (36% 8%); The average wind speed in the most windy direction outdoors in summer is 3.4m / s; The average outdoor wind speed in winter is 1.5m / s, and the most common wind direction in winter is C NNW (50% 9%); The most frequent wind direction in the year is C NNW (40% 7%); The average outdoor wind speed in winter is 3.4m / s; The average wind speed in the most windy direction outdoors in winter is 4.2m / s; The outdoor atmospheric pressure in winter is 901.2hPa; The outdoor atmospheric pressure in summer is 889.6hPa.

[0086] At the same time, the zero-energy data center can be configured to face 30° north-west. The building dimensions of the zero-energy data center are: 60*15*17m (length×width×height). Air storage systems are set on the east and west sides of the zero-energy data center, and the corresponding air supply control room has a size of 5×15×8m (length×width×height).

[0087] Through the design and arrangement of the external form of the zero-energy data center, the path, flow, direction and speed of the outdoor wind field can be controlled. The control of airflow by the building form follows the basic principles of air flow. When considering the air flow in the surrounding environment, the zero-energy data center can be considered as an obstacle to wind at a local or larger regional scale. The air must move around the obstacle or pass through the obstacle. Therefore, the construction of the building form of the zero-energy data center and its orientation and location play a decisive role in achieving zero cooling consumption in cooling.

[0088] Figure 5 The figure shows the characteristics of airflow activity caused by a surface of a zero-energy data center after it is blown by the ambient wind perpendicular to the surface. Figure 5 It can be seen that the outdoor air flow field is actually caused by the obstruction of the zero-energy data center to the airflow. This obstruction generates wind pressure on the windward side, which becomes the driving force for driving air (natural wind) into the computer room 9 of the zero-energy data center. When the air moves along the designed flow path and is finally discharged from the computer room 9 of the zero-energy data center, the zero-energy data center achieves free cooling.

[0089] In the application scenario of the present invention, the architectural form of the zero cooling consumption data center adopts the principle of large width in the east-west direction and small depth in the north-south direction. The ratio of the length of the computer room 9 along the east-west direction to the length of the computer room 9 along the north-south direction is not less than 3:1, and the air storage system is arranged on the east and / or west sides of the computer room 9; for example, the air storage system is configured on the east and west sides of the computer room 9; at the same time, the building orientation of the zero cooling consumption data center and the summer dominant wind direction in the area where it is located are controlled within the range of 45±5 degrees.

[0090] In some embodiments, in order to ensure the reliability of cooling the machine room 9, multiple air storage systems are provided, and at least one of the multiple air storage systems is used as a backup air storage system. That is, the backup air storage system is usually not working, and the other air storage systems are in working state.

[0091] Specifically, the zero cooling data center can be equipped with four air storage systems, two of which are arranged on the west side of the machine room 9, and the air outlet ducts 3 of the two air storage systems are connected to the vents 92 arranged on the outer wall on the west side of the machine room 9; the other two are arranged on the east side of the machine room 9, and the air outlet ducts 3 of the two air storage systems are connected to the vents 92 arranged on the outer wall on the east side of the machine room 9; Among them, the set of air storage system located on the west side of the machine room 9 forms a redundant design of one in use and one in standby, and the set of air storage system located on the east side of the machine room 9 also forms a redundant design of one in use and one in standby.

[0092] In some embodiments, Figure 3 and Figure 4 As shown, a multi-layer top plate 10 is provided in the accommodating space 91 from top to bottom, and the multi-layer top plate 10 divides the accommodating space 91 into multi-layer chambers, and fluid communication is formed between the multi-layer chambers; According to the arrangement order of the compartments from bottom to top, the power of the heating devices stored in the compartments gradually increases; the exhaust skylight 93 is connected to the uppermost one of the multiple compartments.

[0093] According to the arrangement order of the compartments from bottom to top, the compartments are fluidly connected in sequence; all the compartments except the one located at the top are equipped with vents 92. Among them, each compartment can be equipped with multiple vents 92 to ensure balanced cooling of each compartment.

[0094] It can be understood that the vortex wind storage device 1 converts the unstable natural wind from the outside into the stable wind field required by the machine room 9, and transports it to the working area in the machine room 9 through the vents 92, so as to utilize the low-temperature airflow to perform convection heat dissipation on the heat-generating equipment located in the working area, and then discharge the heat-exchanged gas from the exhaust skylight 93.

[0095] By configuring ventilation holes 92 in the multiple rooms except the one located at the top, each ventilation hole 92 can be used to transport cold air to each room below the top, so that a pressure difference is formed between each room at the bottom and the room at the top. By using the principle that hot air floats and cold air sinks, the cold air received in the rooms at different heights is heated by the heating equipment in the corresponding room, resulting in a temperature difference and a density difference, thereby generating free air power to push the hot air in the working area to be discharged to the outside through the exhaust skylight 93.

[0096] As the power of the heating equipment stored in each compartment increases gradually according to the arrangement order of the compartments from bottom to top, the temperature difference and density difference of the air in different compartments arranged along the height direction increase. This design is more conducive to the gas flowing from bottom to top along each compartment in sequence, avoiding heat accumulation in one or more compartments.

[0097] Optionally, two layers of top plates 10 are provided in the accommodating space 91 from top to bottom, and the two layers of top plates 10 divide the accommodating space 91 into three layers of compartments. The heating equipment placed in the compartment on the lowest layer is high and low voltage power distribution cabinets, power batteries, monitoring equipment and other equipment, the heating equipment placed in the compartment on the middle layer is a general computing server, and the heating equipment placed in the compartment on the top layer is an intelligent computing server.

[0098] In some embodiments, Figure 3 As shown, in order to facilitate the control of the air supply area into the compartment, at least one air guide plate 300 is provided on the inner side of the vent 92, and the air guide plate 300 is arranged horizontally or tilted upward; and / or, for the vent 92 of each compartment, the height of the vent 92 relative to the floor where the compartment is located is 300-1500mm.

[0099] Specifically, the air guide plate 300 is rotatably disposed on the inner side of the vent 92, and the angle of the air guide plate 300 relative to the inner wall surface of the machine room 9 can be adjusted between 0-90 degrees to achieve oblique upward air supply toward the room.

[0100] Furthermore, three wind guide plates 300 may be provided, wherein the first wind guide plate 300 is horizontally provided, the second wind guide plate 300 is vertically provided, and the third wind guide plate 300 is tilted upward and located between the first wind guide plate 300 and the second wind guide plate 300 .

[0101] In some embodiments, Figure 3 As shown, in order to ensure the cleanliness of the air in the machine room 9, a filter assembly 200 is provided outside the vent 92, and the filter assembly 200 is used to filter the airflow entering the accommodating space 91. The filter assembly 200 can be a filter screen or filter grille known in the art.

[0102] In some embodiments, Figure 6 As shown, the top plate 10 includes: a storage area 1001 and a hollow area 1002; the storage area 1001 is used to store heating equipment, and the hollow area 1002 is used to achieve fluid communication between the compartments of two adjacent layers; Among them, along the vertical direction, the projections of the storage areas 1001 of each top plate 10 overlap, and the projections of the hollow areas 1002 of each top plate 10 overlap.

[0103] It is understandable that the storage area 1001 can be paved with a steel plate of 600*600mm in size, and earthquake-resistant and reinforced to ensure the safety of the heating equipment. The hollow area 1002 can be paved with a hollow module of 600*600mm in size, the hollow module is in a grid shape, and the size of a single mesh in the hollow module is 50*50mm.

[0104] like Figure 6As shown, by arranging that the projections of the storage areas 1001 of each top plate 10 overlap in the vertical direction, and the projections of the hollow areas 1002 of each top plate 10 overlap, this design can ensure that each compartment forms a vertically connected gas channel based on the hollow area 1002 in the vertical direction, and can avoid heat accumulation in each compartment. Figure 6 Arrows are used to indicate the flow direction of the gas from bottom to top through the hollow area 1002.

[0105] In some embodiments, Figure 3 and Figure 7 As shown, the zero energy consumption data center also includes: a self-heating cabinet 100; the self-heating cabinet 100 has a heat dissipation channel, and the heat dissipation channel is arranged along the length direction of the self-heating cabinet 100; a plurality of heat-generating devices are provided, and the plurality of heat-generating devices are arranged in sequence along the heat dissipation channel. Figure 7 Arrows are used to illustrate the flow direction of gas along the heat dissipation channel.

[0106] In actual applications, the heat-generating equipment stored in the self-heating cabinet 100 is a general computing server or an intelligent computing server. The self-heating cabinet 100 adopts a whole-row rack layout, and the wiring rack is directly integrated on the upper side of the rack. The facade of the rack can be installed with an adjustable guide plate to ensure smooth air flow through the rack. The interior of the self-heating cabinet 100 adopts a transparent method (the partitions between adjacent cabinets are eliminated to make them through), and the air ducts are built into the parallel U positions between the servers, thereby realizing the air supply to the inner cavity of the rack row. The air flows through the surface of the server to achieve the purpose of cooling the server, thereby replacing the function of the fan of the cabinet's own supporting server and realizing the self-heating function of the cabinet itself.

[0107] In the fourth aspect, Figure 8 As shown, the embodiment of the present invention also provides a control method for the zero energy consumption data center as described above, comprising the following steps: Step 810, obtaining the operating power of each heat generating device in the working area of ​​the machine room and the air supply temperature of the eddy current air storage device; Step 820, calculating the total heat generation of the working area according to the operating power of each heat generating device; Step 830, calculating the required air volume of the working area according to the total heat value and the difference between the set temperature of the working area and the supply air temperature; Step 840, controlling the regulating component to adjust the opening of the wind shield according to the required air volume.

[0108] It is understandable that in order to ensure effective cooling of the machine room, according to the principle of energy balance, it should at least be ensured that the cooling capacity input by the vortex air storage device is greater than or equal to the total heating value of the working area, so that the minimum required air volume of the working area can be calculated based on the total heating value of the working area.

[0109] Set the total heat of the working area to Q 总 , the total heat generated in the working area is Q 总 It is the sum of the operating powers of all heat generating devices.

[0110] According to the specific heat capacity formula: Q 总 =M 总 C p (t R -t0); In the above formula: C p is the constant pressure specific heat of air, unit: kJ / (kg・℃), take 1.005kJ / (kg・℃); t R is the set temperature of the working area, which is 30℃; t0 is the supply air temperature of the vortex air storage device, which is 7.2℃.

[0111] The required air volume M of the working area can be obtained from the above formula 总 .

[0112] Furthermore, in the case where a plurality of air storage systems are configured in the machine room, and each air storage system supplies air to the machine room through a plurality of vents, the step of controlling the regulating component to adjust the opening of the air shield according to the required air volume shown in the present invention includes: Determine the air supply volume of each air storage system based on the required air volume; Determine the target opening of the wind shield in the air storage system according to the air supply volume of the air storage system; According to the target opening of the wind shield, the control and regulation component adjusts the opening of the wind shield so that the opening of the wind shield reaches the target opening.

[0113] Among them, according to the target opening of the wind shield, the target angle of the balance bar relative to the horizontal plane can be calculated, and then according to the angle information feedback from the angle sensor, the opening and opening time of the water supply valve can be controlled to ensure that the balance bar reaches the target angle, thereby achieving precise control of the opening of the wind shield.

[0114] Fig. 9 An example of a physical structure diagram of an electronic device is shown in FIG. Fig. 9As shown, the electronic device may include: a processor 910, a communication interface 920, a memory 930 and a communication bus 940, wherein the processor 910, the communication interface 920 and the memory 930 communicate with each other through the communication bus 940. The processor 910 may call the logic instructions in the memory 930 to execute the control method of the zero-energy data center, the method comprising: obtaining the operating power of each heating device in the working area of ​​the computer room and the air supply temperature of the vortex air storage device; calculating the total heat generation of the working area according to the operating power of each heating device; calculating the required air volume of the working area according to the difference between the total heat generation and the set temperature and the air supply temperature of the working area; and controlling the regulating component to adjust the opening of the wind shield according to the required air volume.

[0115] In addition, the logic instructions in the above-mentioned memory 930 can be implemented in the form of a software functional unit and can be stored in a computer-readable storage medium when it is sold or used as an independent product. Based on this understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art or the part of the technical solution, can be embodied in the form of a software product, and the computer software product is stored in a storage medium, including a number of instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to perform all or part of the steps of the method described in each embodiment of the present invention. The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory (ROM, Read-Only Memory), random access memory (RAM, Random Access Memory), disk or optical disk and other media that can store program codes.

[0116] In the fifth aspect, Fig.10 As shown, the present invention also provides an optimization method for the zero-energy data center as described above, comprising the following steps: Step 110, obtaining the absolute temperature of the air inside and outside the computer room, the height difference between the exhaust skylight and the vent of the computer room, and the wind speed in the computer room; Step 120, obtaining the total air dynamics of the computer room according to the absolute temperature difference and height difference between the air inside and outside the computer room, the thermal pressure air dynamics of the computer room, the air density of the vents and the wind speed in the computer room, the wind pressure air dynamics of the computer room, and the sum of the thermal pressure air dynamics and the wind pressure air dynamics; Step 130, obtaining the air resistance in the computer room according to the total air power of the computer room; Step 140, according to the air resistance, adjust the ventilation components corresponding to the computer room so that the current air resistance in the computer room is less than the total air force; wherein the ventilation components include a filter assembly and an air guide plate arranged at the air outlet, and a self-heat exhaust cabinet located in the computer room.

[0117] It is understandable that in order to ensure that the zero-energy data center can be cooled using cold air, a power balance calculation is required to verify whether the air dynamics meet the requirements.

[0118] In practical applications, the principles of fluid mechanics are used to calculate the thermal pressure air power P of a computer room using the following formula: 热 ; P 热 =h(ρ0-ρ R )=K s h(1 / T0-1 / T R ); In the above formula: h is the height difference between the exhaust skylight and the vent of the machine room, unit: m; ρ0 is the air density at the vent, in kg / m 3 ρ R is the air density at the exhaust skylight, in kg / m 3 ; T0 is the absolute temperature of the air at the vent, in K; T R is the absolute temperature of the air in the computer room, in K; K s is a coefficient related to the installation air pressure of the zero energy data center and is taken as 1017.9 kPa・K / m.

[0119] At the same time, the wind pressure aerodynamic force P of the computer room is calculated as follows 风 : P 风 =Kρv / 2; In the above formula: K is the aerodynamic coefficient set in the zero-energy data center, which is 300; ρ is the air density at the set temperature required in the computer room of the zero-energy data center, in kg / m 3 ; v is the average air flow rate in the computer room of the zero-energy data center, in m / s.

[0120] Therefore, the total air force P of the machine room 总 =P 热 + P 风 .

[0121] To ensure the normal air cooling demand of the zero energy data center, the air resistance in the computer room should be set smaller than the total air power P of the computer room. 总, the total air resistance of the filter components, air guide plates, self-exhaust cabinets and structures in the computer room can be calculated. The total air resistance is the maximum resistance along the way from the vent to the exhaust skylight. Therefore, according to the total air resistance, various ventilation components can be selectively configured, and ventilation components that do not meet the air resistance requirements can be replaced to meet the air flow requirements of the zero-energy data center.

[0122] In some embodiments, the method for optimizing a zero-energy data center provided by the present invention further includes: Obtain dust concentration in the air of the computer room; When the dust concentration is greater than a preset value, a prompt message is output to replace the filter component at the ventilation port.

[0123] It is understandable that by setting a PM2.5 sensor at the air vent, the PM2.5 sensor is a device specially designed to detect the concentration of particles with a diameter less than or equal to 2.5 microns in the air. The PM2.5 sensor is used to collect the dust concentration entering the computer room through the air vent.

[0124] When the dust concentration is greater than a preset value, a prompt message can be sent to the user, such as an on-site voice prompt to the user to replace the filter component, or a prompt message to replace the filter component at the vent is sent to the user's terminal device to remind the user to replace the filter component at the vent on time to ensure that the dust concentration in the air in the computer room is less than the preset value.

[0125] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
