Description

Technical Field

[0001] This disclosure relates to the field of cooling equipment technology, and more specifically, to a management system and a cooling equipment. Background Technology

[0002] Indirect evaporative cooling equipment is a device that uses the principle of evaporative cooling to reduce air temperature indirectly. It is widely used in cooling systems in various places such as data centers, industrial plants, and commercial buildings.

[0003] In related technologies, to improve resource utilization, unevaporated coolant is recovered and recycled back into the water tank for reuse. However, during the spraying process, the coolant comes into contact with outdoor air, and impurities in the air enter the water tank along with the recovered coolant, which can cause abnormalities such as clogging of the spray pump, clogging of the filter, and clogging of the end nozzles, leading to abnormal operation of the indirect evaporative cooling equipment. Summary of the Invention

[0004] This summary section is provided to briefly introduce the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0005] In a first aspect, this disclosure provides a management system for a cooling device, the management system including a first flow sensor and a controller. The first flow sensor is disposed in a spray pipe or a drain pipe of the cooling device. The spray pipe is used to transport the coolant of the cooling device from the water tank of the cooling device to the nozzle of the cooling device. The drain pipe is used to transport the coolant recovered from the liquid collection device of the cooling device to the water tank. The first flow sensor is connected to the controller. The first flow sensor is used to detect a first flow rate of the coolant in the spray pipe or the drain pipe. The controller is used to obtain the first flow rate from the first flow sensor. If the first flow rate is lower than a preset flow rate threshold, the controller generates a first prompt message. The first prompt message is used to prompt that at least one of the filter device, the spray pump, and the nozzle of the cooling device be cleaned or replaced.

[0006] In a second aspect, this disclosure provides a cooling device, which includes the management system described in the first aspect.

[0007] The management system for the aforementioned cooling equipment installs a first flow sensor in the spray or drain pipes to detect the initial flow rate of the coolant. The controller then acquires this initial flow rate and generates a notification message indicating that at least one of the cooling equipment's filters, spray pumps, or nozzles needs cleaning or replacement if the initial flow rate falls below a preset threshold. This allows for early warning of abnormal coolant flow, prompting maintenance personnel to perform necessary upkeep and ensure the normal operation of the cooling equipment. For example, in the case of indirect evaporative cooling equipment, it can provide early warnings of problems such as clogged spray pumps, clogged filters, or clogged end nozzles, enabling timely maintenance and ensuring the proper functioning of the indirect evaporative cooling system.

[0008] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0019] It is understood that the above notification and user authorization process are merely illustrative and do not constitute a limitation on the implementation of this disclosure.

[0020] Meanwhile, it is understood that the data involved in this technical solution (including but not limited to the data itself, the acquisition or use of the data) shall comply with the requirements of relevant laws, regulations and related provisions.

[0021] Indirect evaporative cooling equipment can operate in three modes: mixed mode, wet mode, and dry mode. In dry mode, outdoor fresh air and indoor return air directly exchange heat through the heat exchange core, reducing the temperature of the indoor return air to meet the air supply requirements. When dry mode cannot meet the air supply requirements, wet mode is activated, which involves using a spray system to spray coolant onto the outdoor fresh air. The outdoor fresh air absorbs heat through evaporation, reducing its temperature, and then exchanges heat with the indoor return air through the heat exchange core to meet the air supply requirements.

[0022] like Figure 1 In the indirect evaporative cooling device shown, the coolant in the water tank 11 flows out from the water tank outlet 11-2. After being filtered by the filter device 12, the filtered coolant is pumped to the nozzle 14 by the spray pump 13, and then sprayed onto the outdoor fresh air. The outdoor fresh air absorbs heat through evaporation and lowers its temperature. Then, it exchanges heat with the indoor return air through the heat exchange core 15. The spray pipe 17 runs from the water tank outlet to the nozzle. The liquid collection device 16 is correspondingly set with the nozzle 14 to recover the unevaporated coolant. The recovered coolant then flows back to the water tank 11 through the liquid collection device outlet 16-1 and the drain pipe 18. That is, the coolant in the water tank 11 includes the recovered coolant and the new coolant flowing in from the water tank inlet 11-1.

[0023] When the wet mode cannot meet the air supply requirements, the hybrid mode will be activated. This means that both the spray system and the mechanical refrigeration system will be activated simultaneously, with the mechanical refrigeration system supplementing the remaining cooling capacity. Normally, indirect evaporative cooling equipment will only trigger the hybrid mode when the outdoor temperature is high and the spray system alone cannot meet the cooling demand.

[0024] However, during the spraying process, the coolant comes into contact with outdoor air. Impurities such as mud, sand, and willow catkins in the air enter the water tank along with the recovered coolant, affecting the water quality of the coolant in the indirect evaporative cooling system's tank. This can lead to abnormalities such as clogged spray pumps, clogged filters, and clogged end nozzles, causing spray system malfunctions, reduced cooling capacity, and premature activation of the mixing mode. This not only causes abnormal operation of the indirect evaporative cooling system but also increases energy efficiency and wastes resources. In data center scenarios, this can also affect the overall operational stability and energy efficiency management of the data center.

[0025] In view of this, the present disclosure provides a management system and a cooling device for a cooling device to solve the above-mentioned technical problems.

[0026] The embodiments of this disclosure will be further explained below with reference to the accompanying drawings.

[0027] Figure 2 This is a schematic diagram of a management system for a cooling device according to an exemplary embodiment of the present disclosure, with reference to... Figure 2 The management system 20 of the cooling equipment may include the following steps: a first flow sensor 21 and a controller 22, wherein the first flow sensor 21 is connected to the controller 22.

[0028] It should be understood that the first flow sensor 21 and the controller 22 are connected by communication, which can be a wireless communication connection or a wired communication connection, and this disclosure does not limit this connection.

[0029] like Figure 3 As shown, the first flow sensor 21 is installed in the spray pipe 17 or the drain pipe 18 of the cooling equipment, such as flow sensor 21a or flow sensor 21b. The spray pipe 17 is used to transport the coolant of the cooling equipment from the water tank 11 of the cooling equipment to the nozzle 14 of the cooling equipment, and the drain pipe 18 is used to transport the coolant recovered in the liquid collection device 16 of the cooling equipment to the water tank 11.

[0030] The first flow sensor 21 is used to detect the first flow rate of the coolant 18 in the spray pipe 17 or the drainage pipe. For example... Figure 3 As shown, flow sensor 21a detects the coolant flow rate in spray pipe 17, and flow sensor 21b detects the coolant flow rate in drain pipe 18. Controller 22 is used to obtain a first flow rate from the first flow sensor 21, and generate a first prompt message when the first flow rate is lower than a preset flow rate threshold. The first prompt message is used to prompt that at least one of the filter device, spray pump, and nozzles of the cooling equipment should be cleaned or replaced.

[0031] It should be noted that the management system of this embodiment can be applied to indirect evaporative cooling equipment, as well as other cooling equipment that achieves refrigeration function based on coolant. The specific application can be determined according to the actual scenario, and this disclosure does not impose any limitations. The coolant can be water or other liquids, and this disclosure does not impose any limitations on this either.

[0032] For example, the preset flow rate threshold can be set according to requirements. Taking an indirect evaporative cooling device as an example, the minimum flow rate that can maintain the normal operation of the wet mode can be used as the preset flow rate threshold, or a flow rate value larger than the minimum flow rate can be selected as the preset flow rate threshold. This allows for early warning when adjacent modes are switched, and timely cleaning or replacement of components such as filters, spray pumps and nozzles to maintain the normal operation of the wet mode.

[0033] The management system of the aforementioned cooling equipment can provide early warnings of abnormal coolant flow in the cooling equipment, prompting maintenance personnel to perform maintenance and management on the cooling equipment to ensure its normal operation. For example, for indirect evaporative cooling equipment, it can provide early warnings of abnormal problems such as spray pump blockage, filter blockage, and end nozzle blockage, so as to maintain the indirect evaporative cooling equipment in a timely manner and ensure its normal operation.

[0034] In one possible embodiment, the filtration device of the cooling equipment includes a first filtration device for filtering the recovered coolant, and the management system further includes a first water quality detection device, which is located inside the water tank and connected to the controller. The first water quality detection device is used to detect the water quality of the coolant in the water tank and obtain first water quality detection data. The controller is also used to obtain the first water quality detection data from the first water quality detection device. If the first water quality detection data indicates that the water quality of the coolant in the water tank does not meet the preset first water quality conditions, a second prompt message is generated to prompt the first filtration device to be cleaned or replaced.

[0035] In this embodiment, as Figure 3 As shown, the filtration device of the cooling equipment includes a first filter device 19 for filtering the recovered coolant to reduce impurities in the recovered coolant, effectively improve the water quality of the circulating coolant, ensure the normal operation of the cooling equipment, and reduce the maintenance of components such as the filter device 12, spray pump 13, and nozzles 14. For example, adding a first filter device to an indirect evaporative cooling system can reduce spray abnormalities and frequent mode switching caused by water quality issues. It can maintain normal operation in wet mode, with the compressor starting as required, reducing the phenomenon of abnormal wet mode operation and premature compressor start-up due to water quality issues, thus reducing energy efficiency. It also avoids temperature fluctuations causing abnormal temperatures in the data center, improving overall operational stability.

[0036] For example, the first filter device 19 can be installed inside the drain pipe. For an open water tank, the first filter device 19 can be a sheet structure and is covered above the opening of the open water tank by a fastener, so as not to affect the flow rate of coolant in the drain pipe, improve the coolant recovery efficiency, and also to add a cover to the open water tank to prevent impurities in the air from falling into the water tank, thereby further improving the water quality in the water tank.

[0037] For example, such as Figure 3 As shown, a first water quality detection device 31 can be installed in the water tank 11. The first water quality detection device is used to detect the water quality of the coolant in the water tank and obtain the first water quality detection data. For example, water quality detection can determine whether the coolant contains impurities by detecting turbidity. The specific settings can be configured according to the requirements, and this disclosure does not limit it.

[0038] For example, such as Figure 3 As shown, the controller 22 is communicatively connected to the first water quality detection device 31 to obtain the first water quality detection data. If the first water quality detection data indicates that the coolant water quality in the water tank does not meet the preset first water quality conditions, it means that the filtration effect of the first filter device 19 does not meet the water quality requirements. Therefore, a prompt message can be generated to remind the maintenance personnel to clean or replace the first filter device in a timely manner to ensure the normal operation of the cooling equipment.

[0039] In one possible configuration, the cooling equipment's filtration device includes a second filtration device for filtering the coolant in the water supply pipe. The management system further includes a second water quality detection device. A first water quality detection device is located at the outlet of the second filtration device, and the second water quality detection device is connected to a controller. The second water quality detection device is used to detect the water quality of the coolant flowing out of the outlet of the second filtration device and obtain second water quality detection data. The controller is also used to acquire the second water quality detection data from the second water quality detection device. If the second water quality detection data indicates that the water quality of the coolant flowing out of the outlet of the second filtration device does not meet the preset second water quality conditions, a third prompt message is generated. The third prompt message is used to prompt the second filtration device to be cleaned or replaced.

[0040] In this embodiment, as Figure 3 As shown, the filtration device of the cooling equipment includes a second filtration device 12 for filtering the coolant in the water supply pipe. Since the coolant in the water tank 11 includes not only the recovered coolant but also new coolant introduced from the outside, the second filtration device 12 can not only filter the new coolant but also perform secondary filtration on the recovered coolant, thereby further improving the quality of the coolant water entering the downstream components and ensuring the normal operation of the cooling equipment.

[0041] The filter materials of the first filter device and the second filter device can be the same or different. For example, the filter material of the first filter device is filter cotton, and the material of the second filter device is stainless steel filter screen. The specific selection can be made according to the needs, and this disclosure does not impose any restrictions on this.

[0042] For example, such as Figure 3 As shown, a second water quality detection device 32 can be installed at the outlet of the second filter device 12. The second water quality detection device 32 is used to detect the water quality of the coolant after filtration by the second filter device to obtain second water quality detection data. The water quality detection can detect turbidity to determine whether the coolant contains impurities. The specific settings can be configured according to requirements, and this disclosure does not impose any restrictions on this.

[0043] For example, such as Figure 3 As shown, the controller 22 is communicatively connected to the second water quality detection device 32 to obtain the second water quality detection data. If the second water quality detection data indicates that the coolant water quality after filtration by the second filter device does not meet the preset second water quality conditions, it means that the filtration effect of the second filter device 12 does not meet the water quality requirements. Therefore, a prompt message can be generated to remind the maintenance personnel to clean or replace the second filter device in a timely manner to ensure the normal operation of the cooling equipment.

[0044] The first water quality condition and the second water quality condition can be preset turbidity thresholds. They can be the same or different, and can be set according to requirements. This disclosure does not impose any restrictions on them.

[0045] In one possible configuration, there are multiple nozzles, and the management system also includes multiple second flow sensors corresponding one-to-one with the multiple nozzles. Each second flow sensor is located at the corresponding nozzle, and all the multiple second flow sensors are connected to the controller. Each second flow sensor is used to detect the second flow rate of the coolant at the corresponding nozzle. The controller is also used to obtain the corresponding second flow rate from each second flow sensor, and for each second flow sensor, if the second flow rate corresponding to the second flow sensor does not meet the preset flow conditions, generate a fourth prompt message for the first nozzle corresponding to the second flow sensor. The fourth prompt message is used to prompt the first nozzle to be cleaned or replaced.

[0046] In this embodiment, as Figure 3 As shown, the cooling device includes multiple nozzles 14. In order to locate the nozzle that is malfunctioning, a flow sensor can be installed at each nozzle, for example, component 33 is a flow sensor, so that the coolant flow rate at each nozzle can be collected.

[0047] For example, the controller communicates with multiple second flow sensors to obtain the coolant flow rate corresponding to each nozzle. If the coolant flow rate corresponding to a certain nozzle does not meet the preset flow rate condition, it indicates that the nozzle is abnormal, such as being clogged. In this case, a prompt message can be generated to remind the nozzle to be cleaned or replaced. This not only prompts maintenance personnel to handle the problem in a timely manner and ensures the normal operation of the cooling equipment, but also accurately locates the abnormal nozzle, improving the efficiency of maintenance personnel.

[0048] Among them, the situations in which the preset flow conditions are not met may include: the coolant flow rate corresponding to the nozzle is lower than the preset threshold, the difference between the coolant flow rate of the nozzle and the average flow rate of multiple nozzles is greater than the preset difference, etc. The specific settings can be made according to the requirements, and this disclosure does not limit them.

[0049] In one possible configuration, there are multiple nozzles, and the management system also includes multiple water pressure sensors corresponding one-to-one with each nozzle. Each water pressure sensor is located at the corresponding nozzle, and all multiple water pressure sensors are connected to the controller. Each water pressure sensor is used to detect the water pressure of the coolant at the corresponding nozzle. The controller is also used to obtain the corresponding water pressure from each water pressure sensor, and for each water pressure sensor, if the water pressure corresponding to the water pressure sensor does not meet the preset water pressure conditions, generate a fifth prompt message for the second nozzle corresponding to the water pressure sensor. The fifth prompt message is used to prompt the second nozzle to be cleaned or replaced.

[0050] In this embodiment, as Figure 3 As shown, the cooling device includes multiple nozzles 14. In order to locate the nozzle that is malfunctioning, a pressure sensor can be installed at each nozzle, for example, component 33 is a pressure sensor, so that the coolant pressure at each nozzle can be collected.

[0051] For example, the controller communicates with multiple pressure sensors to obtain the coolant pressure corresponding to each nozzle. If the coolant pressure corresponding to a certain nozzle does not meet the preset pressure condition, it indicates that the nozzle is abnormal, such as being clogged. A prompt message can then be generated to remind maintenance personnel to clean or replace the nozzle. This not only alerts maintenance personnel to handle the issue promptly, ensuring the normal operation of the cooling equipment, but also accurately locates the abnormal nozzle, improving the efficiency of maintenance personnel.

[0052] The situations in which the preset pressure conditions are not met may include: the coolant pressure corresponding to the nozzle is lower than the preset threshold, the difference between the coolant pressure of the nozzle and the average pressure of multiple nozzles is greater than the preset difference, etc. The specific settings can be made according to the requirements, and this disclosure does not limit them.

[0053] In some possible ways, the controller is also used to generate a sixth prompt message at preset intervals, which prompts that at least one of the filter, spray pump and nozzles should be cleaned or replaced.

[0054] For example, a reminder message can be generated at preset intervals to prompt maintenance personnel to perform equipment maintenance. In this way, in addition to responding to various early warning messages to handle equipment maintenance immediately, maintenance personnel can also perform periodic equipment maintenance to further ensure the normal operation of the cooling equipment.

[0055] In some possible configurations, the management system also includes an output device connected to the controller; the output device is used to obtain and output the first prompt information from the controller.

[0056] In this embodiment, in addition to outputting the first prompt information mentioned above, the output device can also output other prompt information generated by the controller.

[0057] For example, the output device can be a device with a display screen capable of displaying prompts received from the controller. The prompts can be displayed in text form, such as "Filter device clogged, please clean or replace," or using different symbols, such as a graphic symbol of the filter device, to prompt maintenance personnel to clean or replace it. The output device can also be a device with indicator lights, for example, different indicator lights corresponding to different components of the cooling equipment, such as indicator light 1 corresponding to the filter device, indicator light 2 corresponding to the spray pump, etc. When a particular indicator light is lit, it indicates that the corresponding component is malfunctioning, prompting maintenance personnel to handle it. The output device can also be a communication device used to send the prompts to a remote terminal for display, remotely prompting maintenance personnel to handle the issue. Specific configurations can be made according to requirements, and this disclosure does not impose any limitations. This allows for intuitive malfunction prompts through the output device, facilitating timely intervention by maintenance personnel.

[0058] The management system employing the aforementioned cooling equipment filters the recovered coolant, removing impurities such as silt and willow catkins, effectively improving the coolant quality in the tank. This protects downstream components like the spray pump, secondary filter, and terminal nozzles, extending their lifespan. Furthermore, various sensors provide early warnings of equipment malfunctions, notifying maintenance personnel for repairs and improving management efficiency. It also reduces spray anomalies caused by water quality issues, minimizing frequent mode switching. For example, when applying this indirect evaporative cooling equipment to a data center, it prevents temperature fluctuations from causing abnormal data center temperatures, enhancing operational stability and maximizing the use of wet mode for energy conservation and cost reduction.

[0059] In other possible implementations, a cleaning device can be installed inside the water tank to automatically clean it. A sterilization device can also be installed inside the water tank or at the water tank outlet to sterilize the coolant, etc., and this disclosure does not limit the scope of the invention.

[0060] Based on the same concept, embodiments of this disclosure also provide a cooling device, such as... Figure 4 As shown, the cooling device 40 includes a management system 41.

[0061] In one possible approach, the cooling device is an indirect evaporative cooling device. Of course, other cooling devices that require coolant recovery can also be used, depending on the specific scenario, and this disclosure does not impose any restrictions on this.

[0062] Using the above-mentioned cooling equipment can reduce spray abnormalities caused by water quality issues, ensure the normal operation of the cooling equipment, and effectively extend the service life of the cooling equipment. Taking indirect evaporative cooling equipment applied to data centers as an example, it can avoid temperature fluctuations that cause abnormal temperatures in data centers, improve the operational stability of data centers, and maximize the use of wet mode to achieve the goal of energy saving and consumption reduction.

[0063] In one possible configuration, the cooling device includes a water tank, a liquid collection device, a spray pump, a first filter device, and a second filter device. The first filter device is located between the outlet of the liquid collection device and the water tank. The inlet of the second filter device is connected to the water tank, and the outlet of the second filter device is connected to the spray pump.

[0064] For example, such as Figure 3 The positional relationships between the water tank 11, liquid collection device 16, spray pump 13, nozzle 14, first filter device 19 and second filter device 12 of the cooling equipment and the various sensors and controllers of the management system are shown. For details, please refer to the above-described embodiment of the management system. This disclosure will not repeat them here.

[0065] In this embodiment, as Figure 3 As shown, the first filter device 19 can perform initial filtration of the recovered coolant. Since the coolant in the water tank 11 includes not only the recovered coolant but also new coolant introduced from the outside, the second filter device 12 can not only filter the new coolant but also perform secondary filtration of the recovered coolant, further improving the quality of the coolant entering the downstream components and ensuring the normal operation of the cooling equipment.

[0066] In one possible manner, the filter material of the first filter device is filter cotton.

[0067] For example, the filter material of the first filter device can be filter cotton, or other filter materials capable of filtering impurities such as mud, sand, and willow catkins. The specific material can be selected according to requirements, and this disclosure does not impose any limitations. This effectively filters and recovers impurities from the coolant, protecting the water quality of the circulating coolant.

[0068] For example, the filter materials of the first filter device and the second filter device can be the same or different. For example, the filter material of the first filter device is filter cotton, and the material of the second filter device is stainless steel filter screen. The specific selection can be made according to the needs, and this disclosure does not limit it.

[0069] In one possible configuration, the water tank is an open-type water tank, and the first filter device is a sheet-like structure that is covered above the opening of the open-type water tank by a fastener, so that the first filter device can receive the coolant flowing out of the outlet of the liquid collection device and filter it before it flows into the open-type water tank.

[0070] For example, the water tank of the cooling equipment can be as follows: Figure 3 The open water tank shown can have a first filter device 19 as a sheet structure, which is covered by a fastener at the top of the opening of the open water tank. This does not affect the flow rate of the coolant in the drain pipe, improves the coolant recovery efficiency, and is equivalent to adding a cover to the open water tank to prevent impurities in the air from falling into the water tank, thereby further improving the water quality in the water tank.

[0071] In one possible configuration, the inlet of the first filter is connected to the outlet of the liquid collecting device, and the outlet of the first filter is adapted to be connected to the interior of the water tank so that the first filter filters the coolant flowing out of the outlet of the liquid collecting device before it flows into the water tank.

[0072] For example, such as Figure 5 As shown, the first filter device 19 can also be installed in the drain pipe. The inlet of the first filter device 19 is connected to the outlet of the liquid collection device 16. If a flow sensor is installed in the drain pipe, the recovered coolant can first pass through the flow sensor, then through the first filter device, and then flow back to the water tank. Alternatively, it can first pass through the first filter device, then through the flow sensor, and then flow back to the water tank. The specific choice can be made according to the requirements, and this disclosure does not impose any restrictions on this.

[0073] The method described above, in which the first filter device 19 can also be installed in the drain pipe, is applicable to cooling equipment with open water tanks, semi-closed water tanks, and closed water tanks. It has a wide range of applications. By filtering the recovered coolant, it improves the quality of the coolant and ensures the normal operation of the cooling equipment.

[0074] The above description is merely a preferred embodiment of this disclosure and an explanation of the technical principles employed.

In certain environments, multitasking and parallel processing may be advantageous. Similarly, while several specific implementation details are included in the above discussion, these should not be construed as limiting the scope of this disclosure.
