In this case, the air flow will be spread into the microalgae cultivation center through the openings on the pipeline, and the positions of the heat energy conveying pipeline and the openings can be adjusted in combination with the distribution positions of the microalgae, so as to optimize the air flow, i.e. the specific point of heat energy and carbon dioxide and nitrogen oxide supply, to facilitate optimizing microalgae cultivation, and/or to facilitate optimizing the air flow circulation to reflux the cooled air to the data center.
Preferably, the system further comprises a second exhaust device and a second heat energy conveying pipeline, wherein the second exhaust device discharges air of the microalgae cultivation center to the second heat energy conveying pipeline, and the second heat energy conveying pipeline is communicated with the data center.
The microalgae cultivation center can absorb carbon dioxide, nitrogen oxides, tiny dust and the like in the air and release oxygen, so that the air in the microalgae cultivation center is rich in oxygen through photosynthesis of the microalgae, the tiny dust is removed, corrosive gas to the data center is removed, substances harmful to personnel and equipment in the data center are removed, and meanwhile, the microalgae cultivation center has certain humidity and is beneficial to removing electrostatic effect of the data center.

And then the air flow in the pipe subjected to heat exchange and temperature reduction is continuously managed to return to the air conditioning system of the data center through the second heat energy transmission, and enters a cold channel of the data center after being processed. The air flow which flows back to the data center after heat exchange and temperature reduction of the microalgae cultivation center reduces the refrigeration energy consumption of the air conditioner.

According to the air flow treatment system for the data center, provided by the utility model, hot air required to be discharged in a hot return air area of the data center is discharged to a first heat energy conveying pipeline through a first exhaust device and is introduced into a microalgae cultivation center, heat energy is exchanged to the microalgae cultivation center through a heat exchange pipeline, and the temperature of the microalgae cultivation center is raised by utilizing a tail heat energy source of the data center; the air flow in the heat exchange tube, which is subjected to heat exchange in the microalgae cultivation center and has a reduced temperature, is then conveyed to a data center. Because the cooled air flow is close to the air outlet temperature required by the data center, the refrigerating power of the refrigerating system and the air conditioning system is reduced, and the energy is saved and the consumption is reduced. Specifically, the temperature of the air flow in the hot return air area required to be discharged by the general data center is about 35-40 degrees, and the air flow in the pipeline can raise the temperature of the microalgae cultivation center (the temperature required by the microalgae cultivation center is 25-35 degrees, for example) through the first heat energy conveying pipeline and the heat exchange pipeline. After the heat exchange of the heat exchange pipeline in the microalgae cultivation center, the temperature of the air flow is reduced, and the temperature of the air flow flowing back to the data center through the second heat energy conveying pipeline is close to the temperature of a cold channel required by the data center, namely 18-27 degrees, so that the heat energy contained in the air flow is reasonably and effectively recycled.
In some embodiments, the tail hot air flow discharged from the data center is directly discharged into the microalgae cultivation center to raise the temperature of the microalgae cultivation center, and then air in the space of the microalgae cultivation center is conveyed to the data center through the second exhaust device and the second heat energy conveying pipeline to be used as return air or fresh air of an air conditioning system of the data center. Because microalgae digests carbon dioxide and nitrogen oxides through photosynthesis to produce oxygen in the growth process and has certain humidity to remove dust, air collected from the microalgae cultivation center and returned to the data center is cooled by the microalgae cultivation center, and the temperature of the air can meet the requirements of the data center on fresh air and internal circulation return air temperature. And the air purified by the microalgae culture center removes carbon dioxide, nitrogen oxides, dust and other components harmful to the data center, and simultaneously contains oxygen friendly to operators of the data center and proper humidity, thereby providing high-quality fresh air or return air for the data center. Therefore, according to the data center air flow treatment system and method for the data center, tail heat and air flow components in air flow to be discharged of the data center are effectively utilized, the advantages that solar long soil alkalinity in a high-altitude area is suitable for microalgae growth and the like are utilized, necessary heat is provided for microalgae cultivation, the microalgae cultivation center is utilized for providing cooled air and/or purified air for the data center, the data center is optimized, the air flow energy conservation and consumption reduction efficiency of the microalgae cultivation center is improved, and meanwhile, the method has the effect of green environmental protection.
In the application scene of lower outdoor temperature, the temperature brought by the tail hot air flow discharged by the data center in the system provides a proper temperature environment for microalgae growth of the microalgae culture center. The temperature of the air subjected to heat exchange of the green alga culturing warehouse is lower than the temperature of the tail gas discharged by a data center machine room, but is much higher than the temperature of the tail gas discharged by the outdoor, so that the energy consumption is reduced. For example, when the outdoor temperature is zero in winter scenes in northwest regions, the temperature of the air recovered from the microalgae culture center is 25-30 ℃. The air recovered from the microalgae cultivation center air is the air purified by the microalgae, the discharged carbon dioxide and nitrogen oxides are subjected to microalgae photosynthesis, so that the growth of the microalgae is promoted, the purified air after being converted into oxygen provides favorable working conditions for data center staff, the air in the microalgae pool has proper humidity, the static effect of the data center is removed, and the air is the wet oxygen-enriched purified air required in winter. Therefore, the air which is conveyed back to the data center room by the microalgae cultivation center is provided for the data center room, and the fresh air with low energy consumption and high quality is provided for the data center room.

Fig. 1 illustrates an exemplary diagram of the flow of air to a prior art data center 2. With reference to data center design specifications (GB 50174-2017), racks or cabinets 15 in a data center 2 may be arranged in a face-to-face, back-to-back manner. The front of the rack or cabinet 15 is a cold aisle 16 and the back is a hot aisle 17. The cold and hot channels are isolated. Cool air enters the cabinet 15 from the front and exits the cabinet 15 from the back of the cabinet 15. The temperature range of the air inlet area of the cabinet 15 is 18-27 ℃. The temperature difference between the air supply and the return air is 8-15 ℃. The air flow from the hot aisle 17 is directed by the data center 2 air conditioning system to the hot return air zone 18, which is at a temperature of approximately 35 c to 40 c. The heat of the data center is directly discharged outdoors without being utilized. These hot streams are not utilized, heat is wasted in large amounts, and the surrounding environment may be affected. The direction of the data center 2 airflow is indicated by arrows.

The heat of the data center is directly discharged outdoors without utilization.
Fig. 2 shows a schematic diagram of an air flow treatment system 1 for a data center 2 according to one embodiment of the utility model.
In fig. 2, the hot return air zone 18 of the data center 2 is fitted with a first air exhaust 3. The first exhaust device 3 is communicated with the hot return air area 18 of the data center 2, and discharges hot air of the hot return air area 18 into the first heat energy conveying pipeline 4. The first exhaust device 3 is connected with a first heat energy conveying pipeline 4. The first heat energy transfer line 4 is made of a heat insulating material, and heat energy of hot air circulated therein is maintained. The first heat energy transmission pipeline 4 starts from the data center 2, continues into the microalgae cultivation center 5 and is communicated with the heat exchange pipeline 9 in the microalgae cultivation center 5, and hot air is transmitted from the first heat energy transmission pipeline 4 to the heat exchange pipeline 9.
In this embodiment, the microalgae cultivation center 5 has a cultivation pond 20. The heat exchange line 9 is made of a material having high corrosion resistance, rust resistance, pressure resistance and heat conductivity, and its wall surface may have fins or corrugated contact surfaces for increasing the heat exchange surface area. The heat exchange pipeline 9 connected with the first heat energy conveying pipeline 4 at the air flow upstream extends to the bottom of the culture pond 20, hot air in the pipeline indirectly exchanges heat with the solution in the culture pond 20 through the pipe wall, the microalgae solution close to the heat exchange pipeline 9 rises in temperature and expands in volume due to heating, a natural upturning form is formed in the culture pond 20, meanwhile, the unheated microalgae solution in the culture pond 20 naturally sinks to the surface of the heat exchange pipeline 9 and exchanges heat, and the solution in the whole culture pond 20 can be heated circularly and uniformly, and timely exchange of oxygen and carbon dioxide in the pond is ensured. These are very advantageous for the growth of microalgae. The tail heat of the data center 2 provides the required temperature for microalgae cultivation and is utilized.
After heat exchange, the temperature of the water in the microalgae culture pond 20 rises, and the temperature of the air in the heat exchange pipeline 9 decreases. The cooled air is returned to the data center 2 through a second heat energy transfer line 8 connected downstream of the air flow with a heat exchange line 9. The second thermal energy transfer line 8 may also be made of a thermally insulating material so that the temperature of the air flow in the line can be maintained.

The differences between the embodiment of fig. 3 and the embodiment of fig. 2 will be mainly described below.
The embodiment of fig. 3 differs from the embodiment of fig. 2 in that:
the air flow in the embodiment shown in fig. 2 always circulates in the pipeline, and exchanges heat with the microalgae cultivation center 5 through the wall of the heat exchange pipeline and the microalgae cultivation pond water to raise the temperature in the microalgae cultivation center 5 and cool the air flow flowing back to the data center 2.
In the embodiment shown in fig. 3, the first heat energy transmission pipeline 4 has a plurality of openings 6 in the microalgae cultivation center 5, and the air flow in the first heat energy pipeline passes through the openings 6 and is dispersed at the position favorable for microalgae cultivation, and the hot air from the data center 2 is mixed with the air in the microalgae cultivation center 5, so that the temperature in the microalgae cultivation center 5 is increased, and carbon dioxide required by microalgae growth is brought; in the growth process of the microalgae, oxygen is released, tiny dust is removed, the temperature and the humidity are favorably adjusted, and the air is purified. In this embodiment, a second exhaust device 7 is disposed in the microalgae cultivation center 5, and exhausts the air in the microalgae cultivation center 5 to a second heat energy conveying pipeline 8, and the air is conveyed to an air conditioning system of the data center 2, processed by the air conditioning system, and then discharged into a cold channel 16 of the data center. The air in the microalgae cultivation center 5 is lower than the temperature of the hot return air area of the data center 2 and is closer to the temperature of the cold channel of the data center 2.
Fig. 4 illustrates a control flow diagram of the data center 2 airflow control system according to the present utility model. In this embodiment, the sensor 10 tests the pool water temperature and the pressure sensor tests the air pressure of the cold and hot channels of the data center, and the measured data is transmitted to the control center 12. After the system is started, in an initial mode, the rotating speed of the first air exhaust device 3 is 50%, the opening of the bypass valve 14 and the electric air valve 11 is 50%, and the pool water setting temperature SP; the time t1 is run under this condition. After the time T1 has elapsed, the sensor 10 tests the temperature of the pool water of the culture pool 20 and the control center calculates the difference Δt between the pool water temperature PV and the set temperature SP. Performing PID (proportion integration differentiation) operation, and readjusting the start-stop and operation of the first air exhaust device 3 and the opening degrees of the bypass valve 14 and the electric air valve 11 according to the delta T and a preset threshold value, namely closing the electric air valve 11 and increasing the bypass valve 14 when the delta T is positive deviation, wherein the rotating speed of the first air exhaust device 3 is reduced, and the lower rotating speed limit of the first air exhaust device 3 is that the pressure difference of a cold-hot channel is kept not lower than a minimum set value; when Δt is negative deviation, the electric damper 11 is increased, the bypass valve 14 is decreased, the rotation speed of the first exhaust device 3 is increased, and the upper limit of the rotation speed of the first exhaust device 3 is: the pressure difference of the cold and hot channels is kept not higher than the maximum set value of the pressure difference. Through the control flow, the stability of the temperature and the pressure difference of the cold and hot channels of the data center airflow treatment system 1 is kept.
In this embodiment, the main control parameter is the pool temperature PV, and the pool temperature value SP is set. Through PV and SP parameter calculation, the control center needs to control: the first exhaust device 3 is turned on and off and operated, and the opening of the electrically operated damper 11 and/or the bypass valve 14 is located in the first thermal energy transfer line 4. PID operation is performed by the PV value and the SP value. When loading, the electric air valve 11 and the bypass valve 14 in the first heat energy conveying pipeline 4 are firstly regulated, then the first air exhaust device 3 is regulated, when unloading, the electric air valve 11 and the bypass valve 14 in the first heat energy conveying pipeline 4 are firstly regulated, and in operation, the positions are reciprocally regulated, so that the system reaches balance.
Specifically, after the control center 12 is started, the system enters an initial mode, at this time, the rotation speed of the first exhaust device 3 is 50%, the opening of the electric air valve 11 and the bypass valve 14 in the first heat energy conveying pipeline 4 is 50% (adjustable), and the air flow treatment system 1 circulates for a time t0, for example, 3 minutes (adjustable). t0, for example, after a 3 minute (adjustable) time has elapsed, the system enters an automatic adjustment mode, where each device is adjusted according to the PID calculated value and a predetermined threshold value. If the difference delta T between the pool water temperature PV and the set temperature SP is negative deviation compared with a preset threshold value, firstly reducing the rotating speed of the first air exhaust device 3, and when the rotating speed is reduced to the minimum rotating speed, the lower rotating speed limit of the first air exhaust device 3 is that the pressure difference of the cold and hot channels is kept not lower than the minimum set value, and then the opening of the electric air valve 11 in the first heat energy conveying pipeline 4 is reduced; the opening degree of the bypass valve 14 is increased, and the correspondence relationship between these two valve opening degrees is inversely proportional. If the difference Δt between the pool water temperature PV and the set temperature is positive in comparison with the predetermined threshold value, then the system 1 is loaded with two cases at this time, first: when the loading requirement is lower, the electric air valve 11 and the bypass valve 14 in the first heat energy conveying pipeline 4 are regulated, the first air exhaust device 3 is reduced to the minimum rotating speed, and the lower rotating speed limit of the first air exhaust device 3 is that the pressure difference of the cold and hot channels is kept not lower than the minimum set value. Second,: when the loading demand is high, the electric air valve 11 in the first heat energy conveying pipeline 4 and the bypass valve 14 still do not meet the requirement that deltat is at the target value after being regulated, at this time, the electric air valve 11 in the first heat energy conveying pipeline 4 is opened to the maximum, the bypass valve 14 is closed, the rotation speed of the first air exhaust device 3 starts to be regulated, the rotation speed is increased until the maximum rotation speed, and the upper limit of the rotation speed of the first air exhaust device 3 is as follows: the pressure difference of the cold and hot channels is kept not higher than the maximum set value of the pressure difference. According to the loading and unloading mode, the dynamic adjustment stabilizes the temperature and the air pressure required by the system.
It should be understood that the above embodiment of the solution for controlling the temperature and the pressure difference of the cold and hot channels is not to be construed as limiting the present utility model. According to the system and method of the present utility model, various environmental indices such as air pressure, temperature, humidity, carbon dioxide content, oxygen content, and/or dust content in the air flow treatment system 1 may also be controlled by adjusting the type and number of sensors 10, adjusting predetermined thresholds, and/or using other calculation methods, as desired.

The air flow in the microalgae cultivation center 5 can be as shown in fig. 2, namely, the air flow transmitted from the first heat energy transmission pipeline 4 flows to the heat exchange pipeline 9 connected with the first heat energy transmission pipeline 4, the hot air flow in the pipeline is converted with pond water at the bottom of the microalgae cultivation pond 20 through the surface of the heat exchange pipeline, so that the temperature of the pond water is increased, the temperature of the air flow in the pipeline is reduced, and then the air flow after heat exchange continues to the second heat energy transmission pipeline 8 connected with the heat exchange pipeline 9 and is transmitted to the outside of the microalgae cultivation center 5, and is divided into three paths to be transmitted to the three data centers 2. The air conditioning system of the three data centers 2 processes the air flow flowing back from the microalgae cultivation center 5 and then discharges the air flow to the cold tunnel 16.
