Description

Technical Field

[0001] This disclosure relates to the field of computer technology, and more particularly to the fields of data centers and cooling technology, and especially to a data center cooling system and its control method. Background Technology

[0002] Indirect evaporative cooling systems typically use plate-fin cores to cool electronic equipment. These systems rely on sensible heat exchange to cool the return air from the server room. The sprayed water forms a film only on the outer surface of the core, preventing direct air contact with the water. This offers advantages such as no humidification required, no water carryover, and reduced icing in winter. Currently, in saline-alkali areas, data center cooling systems often include water softening and reverse osmosis (RO) units to purify the circulating water.

Detailed Implementation

[0011] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0012] This disclosure presents a data center cooling system and its control method.

[0013] Figure 1 This is a schematic diagram according to the first embodiment of the present disclosure.

[0014] like Figure 1 As shown, the data center cooling system 100 may include: Indirect evaporative cooling unit 110, wherein the indirect evaporative cooling unit 110 includes: a circulating water tank 111.

[0015] The water softening unit 120 is connected to the circulating water tank 111.

[0016] The reverse osmosis unit 130 is connected to the water softening unit 120 and the circulating water tank 111, respectively.

[0017] Algae culture device 140 is connected to reverse osmosis unit 130, and algae culture device 140 includes water quality detector 141.

[0018] The controller 150 is connected to the water softening unit 120, the reverse osmosis unit 130, and the water quality detector 141, respectively.

[0019] The controller 150 is used to control the flow of circulating water in the circulating water tank 111 into the water softening unit 120.

[0020] The water softening unit 120 is used to soften circulating water using ion exchange resin.

[0021] The reverse osmosis unit 130 is used to perform reverse osmosis treatment on the water output from the water softening unit 120, and to transport the permeate produced by the reverse osmosis treatment to the circulating water tank 111, and to transport the concentrate produced by the reverse osmosis treatment to the algae culture device 140.

[0022] In this embodiment, the permeate produced by reverse osmosis is transported to a circulating water tank, thereby realizing the recycling of water in the data center cooling system and significantly improving the water utilization rate of the data center cooling system.

[0023] Algae culture vessel 140 is used to cultivate salt-tolerant algae in the algae culture vessel 140 by means of concentrated water.

[0024] It should be noted that the salt-tolerant algae in this embodiment can absorb salt, nitrogen, phosphorus, and organic matter in concentrated water, thereby achieving the purification of concentrated water.

[0025] In some embodiments, the controller 150 is further configured to control the water in the algae culture 140 to be delivered to the plant irrigation system so that the plant irrigation system irrigates the plants, provided that the water quality in the algae culture 140 meets the irrigation water standards as determined by the water quality detector 141.

[0026] In some embodiments, the water quality detector 141 in this embodiment detects the water quality of the algae culture device 140 to obtain the water quality of the algae culture device 140, and sends the water quality to the controller 150. Correspondingly, the controller 150 judges the water quality based on the irrigation water standard, and if it is determined that the water quality meets the irrigation water standard, it controls the water in the algae culture device 140 to be transported to the plant irrigation system so that the plant irrigation system irrigates the plants.

[0027] In some embodiments, the plant irrigation system may use drip irrigation or sprinkler irrigation to irrigate the plants, and this embodiment does not specifically limit this.

[0028] In some embodiments, in order to make full use of water resources, the plant irrigation system in this embodiment may also include a humidity detector, which is used to detect the humidity of the plant. When the humidity of the plant is detected to be less than a preset humidity threshold, the plant irrigation system may irrigate the plant with water.

[0029] It should be noted that, in addition to the circulating water tank, the indirect evaporative cooling unit 110 in this embodiment may also include other components. For details on the other components included in the indirect evaporative cooling unit 110, please refer to the relevant descriptions in the related art, which will not be repeated here.

[0030] The data center cooling system provided in this embodiment utilizes an algae culture device connected to a reverse osmosis unit. This allows the algae culture device to cultivate salt-tolerant algae using the concentrated water produced by the reverse osmosis unit. During the cultivation process, the water quality in the algae culture device is monitored. If the water quality meets irrigation standards, the water is directed to a plant irrigation system for watering the plants. Thus, the algae culture device effectively treats the concentrated water from the reverse osmosis unit, and the treated water is used to irrigate the plants, achieving efficient utilization of the concentrated water and avoiding environmental pollution.

[0031] Based on the above embodiments, in order to effectively avoid ineffective treatment, significantly reduce energy consumption, chemical consumption and equipment wear, and ensure that the system always operates within a safe water quality range, Figure 1 Based on the embodiments shown, such as Figure 2 As shown, the indirect evaporative cooling unit 110 also includes: a conductivity detector 112; Conductivity detector 112 is used to detect the conductivity of the circulating water in the circulating water tank 111 and send the conductivity to controller 150.

[0032] The controller 150 is also used to control the circulating water in the circulating water tank 111 to flow into the water softening unit 120 when it is determined that the conductivity exceeds a preset conductivity threshold.

[0033] In some embodiments, such as Figure 2 As shown, an ultraviolet sterilization unit 160 is installed between the water softening unit 120 and the circulating water tank 111.

[0034] The controller 150 is also used to control the flow of circulating water in the circulating water tank 111 into the water softening unit 120 after passing through the ultraviolet sterilization unit 160. Thus, the ultraviolet sterilization unit 160 achieves sterilization treatment of the circulating water, which helps to reduce the impact of bacteria in the circulating water on subsequent treatment and avoids biofouling of the reverse osmosis membrane in the reverse osmosis unit 130.

[0035] In some embodiments, the ultraviolet sterilization unit 160 can sterilize the circulating water using an ultraviolet lamp.

[0036] In some embodiments, the controller 150 in this embodiment can also be connected to the ultraviolet sterilization unit 160 to control the opening and closing of the ultraviolet lamps in the ultraviolet sterilization unit 160.

[0037] In some embodiments, the data center cooling system 100 may further include: an activated carbon adsorption unit 170 disposed between the ultraviolet sterilization unit 160 and the water softening unit 120. The controller 150 is also used to control the circulating water in the circulating water tank 111 to flow into the water softening unit 120 after passing through the ultraviolet sterilization unit 120 and the activated carbon adsorption unit 170 in sequence.

[0038] In this embodiment, by passing the circulating water through the activated carbon adsorption unit 170, the activated carbon adsorption unit 170 can adsorb impurities in the circulating water, thereby preventing the reverse osmosis membrane from undergoing oxidative degradation and organic fouling.

[0039] In other embodiments, to ensure that the water in the circulating water tank 111 is maintained at a certain level, the inlet of the activated carbon adsorption unit 170 in this embodiment is also connected to the municipal water supply network to receive water from the municipal water supply system. Thus, water from the municipal water supply network is used to replenish the water in the circulating water tank 111, maintaining the water level in the circulating water tank 111.

[0040] In some embodiments, a dosing device (not shown) is provided at the inlet of the reverse osmosis unit 130 for adding a composite water treatment agent to the feed water. This composite water treatment agent contains scale inhibitors and bactericides. Therefore, by adding the composite water treatment agent to the water, biofouling and silica scale deposition on the reverse osmosis membrane can be inhibited, ensuring the stable operation life of the RO membrane and reducing system maintenance costs.

[0041] In other embodiments, such as Figure 2 As shown, the data center cooling system 100 may further include: The brine recovery unit 180 is connected to the algae culture device 140 and the water softening unit 120 respectively, and is used to obtain brine from the water in the algae culture device 140 and transport the brine to the water softening unit 120.

[0042] The water softening unit 120 is also used to regenerate spent ion exchange resins using brine. This achieves the regeneration of spent ion exchange resins through the recovery of brine, realizing internal recycling of brine resources, reducing the need for external salt purchases, and lowering maintenance costs.

[0043] In some embodiments, after the brine recovery unit 180 obtains water from the algae culture device 140, it can store the water in a gravity sedimentation tank for a preset time. After the preset storage time is reached, the water in the gravity sedimentation tank is treated to remove suspended solids and sediments. Then, the water in the gravity sedimentation tank is treated to soften with lime milk and filtered through sand filter + activated carbon to further remove organic matter and color.

[0044] The preset duration is a duration set in advance according to actual needs; for example, the preset duration can be 8 hours.

[0045] In some embodiments, lime milk softening treatment can prevent resin scaling.

[0046] In some embodiments, after obtaining the brine, the concentration of the brine can be determined by a brine concentration detector to determine whether the concentration of the brine exceeds a preset concentration threshold. If the concentration of the brine exceeds the preset concentration threshold, the brine is transported to the water softening unit 120.

[0047] In other embodiments, if it is determined that the concentration of the brine does not exceed a preset concentration threshold, the brine can be concentrated to make the concentration of the brine exceed the preset concentration threshold.

[0048] It should be noted that the above is only an example of one possible implementation of the brine recovery unit 180 obtaining brine from the water in the algae culture device 140. The brine recovery unit 180 can also obtain brine in other ways, and this embodiment does not impose any specific limitations on this.

[0049] In some embodiments, a filter screen (not shown in the figure) is provided at the air inlet of the indirect evaporative cooling unit 110 in this embodiment, and a differential pressure detector (not shown in the figure) is provided between the air inlet side and the air outlet side of the filter screen. The data center cooling system 100 also includes: a backflush cleaning unit (not shown in the figure), wherein the nozzle of the backflush cleaning unit faces the air outlet side surface of the filter screen; The controller 150 is also used to control the backflush cleaning unit to spray compressed air to remove dust accumulated on the air inlet side surface of the filter screen when the differential pressure detected by the differential pressure detector exceeds a preset differential pressure threshold. Thus, the backflush cleaning unit automatically removes dust accumulated on the air inlet filter screen of the indirect evaporative cooling unit 110, helping to reduce system maintenance costs.

[0050] The preset differential pressure threshold is a differential pressure threshold set in advance according to actual needs. This embodiment does not specifically limit the value of the preset differential pressure threshold.

[0051] In some embodiments, to reduce dust accumulation on the filter screen, plants can be planted at the air inlet of the indirect evaporative cooling unit 110. This helps to reduce the air velocity and coarse particulate dust concentration on the inlet side, physically blocks fibrous pollutants such as willow catkins, and slows down the dust accumulation rate on the filter screen when configured on the windward side, thus extending the maintenance cycle.

[0052] One example illustration shows plants being grown at the air inlet of the indirect evaporative cooling unit 110, such as... Figure 3 As shown. It should be noted that a filter is installed at the air inlet. Figure 3 The filter screen is not shown in the example.

[0053] This can be understood as follows: the plants can be irrigated using water from the plant irrigation system, and fertilized using algae fertilizer from the plant fertilization system. This promotes tree growth and forms a closed-loop system of "wastewater utilization – ecological construction – operation and maintenance coordination".

[0054] In some embodiments, the filter screen in this embodiment may also be a filter screen with dustproof function, which can further reduce dust accumulation on the filter screen, slow down the dust accumulation rate of the filter screen, and help reduce system maintenance costs.

[0055] In some embodiments, such as Figure 2 As shown, the data center cooling system 100 in this embodiment may further include: The algal fertilizer preparation unit 190 is used to prepare salt-tolerant algae from the algae culture vessel 140 to obtain algal fertilizer, and then deliver the algal fertilizer to the plant fertilization system so that the plant fertilization system can fertilize the plants with the algal fertilizer. This achieves the reuse of salt-tolerant algae in the algae culture vessel 140 and promotes plant growth.

[0056] In some embodiments, after determining that the salt-tolerant algae in the algae culturer are mature, the salt-tolerant algae in the algae culturer 140 are transported to the algae fertilizer preparation unit 190, which can prepare fertilizer from the salt-tolerant algae to obtain algae fertilizer.

[0057] It should be noted that the process of preparing fertilizer from salt-tolerant algae to obtain algal fertilizer can be found in the relevant descriptions in the related technologies, and will not be repeated here.

[0058] Based on any of the above embodiments, the data center cooling system 100 in this embodiment may further include: an ambient temperature detector (not shown in the figure).

[0059] The ambient temperature detector is connected to the controller 150. The ambient temperature detector is used to detect the ambient temperature to obtain the ambient temperature and send the ambient temperature to the controller 150.

[0060] The controller 150 is also used to control the operating mode of the indirect evaporative cooling unit 110 to dry mode when the ambient temperature is determined to be less than or equal to a preset temperature threshold, and to control the water softening unit 120 and the reverse osmosis unit 130 to stop working, so that no more concentrated water is generated.

[0061] It is understood that when the indirect evaporative cooling unit 110 is operating in dry mode, the spray system in the indirect evaporative cooling unit 110 will stop working.

[0062] It is understandable that when the indirect evaporative cooling unit 110 is in dry mode, the sprayed water in the indirect evaporative cooling unit 110 forms a wall-adhering water film on the outer surface of the core body. Outdoor air passes through the gaps between the fins, and only sensible heat exchange occurs. There is no humidification, no water droplets, and no freezing in winter.

[0063] In some embodiments, the data center cooling system 100 in this embodiment may further include a buffer storage tank for storing concentrated water generated by the humidification system of the data center when the indirect evaporative cooling unit 110 is operating in dry mode. Correspondingly, the controller 150 is also used to deliver the concentrated water in the buffer storage tank to the algae culture device 140 when it is determined that the operating mode of the indirect evaporative cooling unit 110 is cooling mode.

[0064] It should be noted that when the indirect evaporative cooling unit 110 is in dry mode, the algae culture device 140 is in maintenance mode.

[0065] In some embodiments, in order to keep the algae culture 140 in maintenance mode, the algae culture 140 may also be equipped with an electric heating device to maintain the temperature inside the algae culture 140 at no less than 8°C, maintain the activity of algae strains with minimal energy consumption, and not pursue growth output.

[0066] It should be noted that the algae culture device 140 in this embodiment is a closed device, for example, the algae culture device 140 can be a closed tank.

[0067] In some embodiments, the controller 150 is further configured to control the operating mode of the indirect evaporative cooling unit 110 to cooling mode when it is determined that the ambient temperature is greater than a preset temperature threshold, and to control the water softening unit 120 and the reverse osmosis unit 130 to start working.

[0068] The preset temperature threshold is a temperature threshold set in advance based on actual conditions. This embodiment does not specifically limit the value of the preset temperature threshold.

[0069] It is understood that when the indirect evaporative cooling unit 110 is in cooling mode, the spray system of the indirect evaporative cooling unit 110 will start working.

[0070] It is understood that when the indirect evaporative cooling unit 110 is in cooling mode, the ultraviolet sterilization unit 160 and the activated carbon adsorption unit 170 in the data center cooling system 100 are both in the on state.

[0071] Figure 4 This is a schematic diagram based on the third embodiment of this disclosure. It should be noted that the control method in this embodiment is applied to the data center cooling system disclosed in this disclosure. The following is a detailed explanation... Figure 1 and Figure 2The example data center cooling system and its control method are described exemplarily. It should be noted that this embodiment uses the example of the control method being executed by a controller within the data center cooling system for exemplary description.

[0072] like Figure 4 As shown, it may include: Step 401: Control the flow of circulating water from the circulating water tank into the water softening unit.

[0073] In some embodiments, one possible implementation of controlling the flow of circulating water from the circulating water tank into the water softening unit is as follows: the conductivity of the circulating water in the circulating water tank is detected by a conductivity detector; if the conductivity exceeds a preset conductivity threshold, the flow of circulating water from the circulating water tank into the water softening unit is controlled. This effectively avoids ineffective treatment, significantly reduces energy consumption, chemical consumption, and equipment wear, while ensuring that the system always operates within a safe water quality range.

[0074] Step 402: The circulating water is softened using an ion exchange resin via a water softening unit.

[0075] Step 403: The water output from the water softening unit is subjected to reverse osmosis treatment through the reverse osmosis unit, and the permeate produced by the reverse osmosis treatment is transported to the circulating water tank, and the concentrate produced by the reverse osmosis treatment is transported to the algae culture device.

[0076] Step 404: Cultivate salt-tolerant algae in the algae culture vessel using concentrated water.

[0077] Step 405: If the water quality in the algae culture vessel meets the irrigation water standards as determined by the water quality detector, control the water in the algae culture vessel to be transported to the plant irrigation system so that the plant irrigation system can irrigate the plants.

[0078] The control method provided in this disclosure controls an algae culture device in a data center cooling system. When the water quality meets irrigation standards, the method controls the water in the algae culture device to be delivered to a plant irrigation system, allowing the system to irrigate the plants. This achieves precise control of the concentrated wastewater treatment process, thereby efficiently utilizing concentrated wastewater resources and protecting the natural environment.

[0079] Based on the above embodiments, in the case of a data center cooling system including a brine recovery unit, the method can further perform the following operations: controlling the brine recovery unit to obtain brine from the water in the algae culture device and transporting the brine to the water softening unit; controlling the water softening unit to regenerate the degraded ion exchange resin based on the brine. Thus, the regeneration of the degraded ion exchange resin is achieved through the recovered brine, realizing the internal circulation of brine resources, reducing the need for external salt purchases, and lowering maintenance costs.

[0080] In some embodiments, a filter screen is installed at the air inlet of the indirect evaporative cooling unit in the data center cooling system, and a differential pressure detector is installed between the air inlet side and the air outlet side of the filter screen. The data center cooling system also includes a backflushing cleaning unit, with its nozzle facing the air outlet surface of the filter screen. The method can further perform the following operations: when the differential pressure detected by the differential pressure detector exceeds a preset differential pressure threshold, control the backflushing cleaning unit to spray compressed air to remove dust accumulated on the air inlet surface of the filter screen. Thus, by controlling the backflushing cleaning unit, automatic dust removal from the filter screen at the air inlet of the indirect evaporative cooling unit 110 is achieved, improving the system's unattended operation capability and reducing maintenance complexity.

[0081] In some embodiments, where the data center cooling system further includes an algae fertilizer preparation unit, the method can also perform the following operations: controlling the algae fertilizer preparation unit to prepare salt-tolerant algae from an algae culture vessel to obtain algae fertilizer, and delivering the algae fertilizer to a plant fertilization system so that the plant fertilization system fertilizes the plants with the algae fertilizer. This achieves effective control of the algae fertilizer preparation unit, contributing to improved system operational stability and automation.

[0082] In some embodiments, in order to clearly understand the control method of this disclosure, the following is combined with Figure 5 The control method of this embodiment is described by way of example.

[0083] Figure 5 This is a schematic diagram according to the fourth embodiment of the present disclosure.

[0084] like Figure 5 As shown, the method may include: Step 501: Detect the conductivity of the circulating water in the circulating water tank using a conductivity detector.

[0085] Step 502: Determine whether the conductivity exceeds the preset conductivity threshold. If yes, proceed to step 503; otherwise, continue with step 502.

[0086] Step 503: Control the flow of circulating water in the circulating water tank into the ultraviolet sterilization unit.

[0087] Step 504: The water output from the ultraviolet sterilization unit is transported to the activated carbon adsorption unit, and the water from the municipal water supply network is also transported to the activated carbon adsorption unit.

[0088] Step 505: The water output from the activated carbon adsorption unit is transported to the water softening unit.

[0089] Step 506: The water output from the water softening unit is transported to the reverse osmosis unit.

[0090] Step 507: The permeate obtained from the reverse osmosis unit is transported to the circulating water tank.

[0091] Step 508: The concentrated water obtained from the reverse osmosis unit is transported to the algae culture vessel to cultivate salt- and alkali-tolerant algae in the algae culture vessel through the concentrated water.

[0092] Step 509: The brine recovery unit recovers brine from the water in the algae culture vessel to obtain brine.

[0093] Step 510: The brine recovery unit transports the recovered brine to the water softening unit.

[0094] The water softening unit can regenerate the depleted ion exchange resin using brine to obtain an effective ion exchange resin.

[0095] Step 511: If the water quality in the algae culture vessel meets the irrigation water standards, control the water in the algae culture vessel to be delivered to the plant irrigation system so that the plant irrigation system can irrigate the plants.

[0096] Step 512: The salt- and alkali-tolerant algae in the algae culture device are transported to the algae fertilizer preparation unit.

[0097] Step 513: The algae fertilizer preparation unit prepares salt-tolerant algae in the algae culture device to obtain algae fertilizer, and delivers the algae fertilizer to the plant fertilization system so that the plant fertilization system can fertilize the plants through the algae fertilizer.

[0098] It is understandable that, unless otherwise specified, the sequential order of the steps in the process indicates that the temporal relationship between these steps is not limited.
