Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a spray cooling system, air conditioning equipment and device. Background Technology

[0002] With the rapid development of the Internet and the Internet of Things (IoT), the demand for information and data processing has surged. Large telecommunications companies, banks, financial services firms, and internet companies are experiencing continuous growth in data traffic, making it difficult for traditional data centers to meet the energy demands of their expanding businesses. The enormous annual energy consumption not only increases operating costs but also poses a challenge to companies' market competitiveness and sustainable development. Therefore, developing more efficient and energy-saving data center cooling solutions has become a focus of industry attention. Spray cooling systems (also referred to as "spray systems" in this article), as an innovative energy-saving technology, are gaining increasing popularity among companies due to their significant advantages in reducing energy consumption and improving energy efficiency.

[0003] Spray cooling systems maximize the spray area by combining the selection of high-efficiency condensers, optimizing water system piping and nozzle design, and rationally configuring water pumps. This system atomizes water and sprays it onto the outdoor environment or the air intake side of the air conditioning condenser, utilizing the heat absorption properties of water evaporation to effectively reduce the ambient temperature, thereby improving the condenser's heat exchange efficiency, reducing the compressor load, and ultimately lowering overall energy consumption. As a highly efficient and energy-saving cooling solution, spray cooling systems are gradually becoming an important direction for data center energy-saving renovations. With the continuous maturation of technology and the gradual reduction in costs, its market application prospects are broad, and it is expected to achieve large-scale promotion in the next few years.

[0004] However, outdoor spray units are used cyclically during seasonal use. Conventional spray systems only have temperature-controlled spray on / off switches. After prolonged spraying, the surrounding air humidity is high. If spraying continues at this time, water droplets will not evaporate easily and will adhere to the condenser fins, blocking the airflow channels and affecting the heat exchange performance of the condenser. This is not conducive to water conservation and energy consumption reduction.

[0005] Meanwhile, current spray cooling systems require air compressors and softened water pumps, which are high-energy-consuming components and result in complex structures and high costs for spray cooling systems. Utility Model Content

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0035] Figure 1 A schematic diagram of a spray cooling system provided in an embodiment of this utility model is shown below. Figure 1 As shown, the spray cooling system includes:

[0036] 1. Water inlet pipe; 2. Water inlet solenoid valve; 4. Water pump; 9. First spray solenoid valve; 11. First spray module; 13. First spray outdoor unit;

[0037] The water inlet pipe 1 is connected to one end of the water inlet solenoid valve 2; the other end of the water inlet solenoid valve 2 is connected to the inlet of the water pump 4, and the outlet of the water pump 4 is connected to one end of the first spray solenoid valve 9; the other end of the first spray solenoid valve 9 is connected to the inlet of the first spray module 11, and the outlet of the first spray module 11 is connected to the inlet of the first spray outdoor unit 13.

[0038] The coolant flows from the inlet pipe 1 through the inlet solenoid valve 2 and then into the water pump 4; after flowing out of the water pump 4, it flows through the first spray solenoid valve 9 into the first spray module 11, and then flows out of the first spray module 11 into the first spray outdoor unit 13.

[0039] The spray cooling system provided in this embodiment of the invention eliminates the need for an air compressor and uses a simpler structure such as a water inlet pipe and a regular water pump, thereby simplifying the structure of the spray cooling system and reducing costs.

[0040] Optionally, such as Figure 1 As shown, the system also includes an outdoor temperature and humidity sensor 15, used to collect outdoor temperature and humidity data.

[0041] For example, the outdoor temperature and humidity sensor 15 can be installed on the side of the first spray unit 13 closest to the outside.

[0042] Optionally, the system also includes: a main control board ( Figure 1 (Main control board and electrical connections not shown); Water inlet solenoid valve 2, water pump 4, first spray solenoid valve 9, first spray module 11, and outdoor temperature and humidity sensor 15 are all electrically connected to the main control board;

[0043] The main control board is used to acquire the outdoor temperature and humidity collected by the outdoor temperature and humidity sensor 15, and to control the opening or closing of the water inlet solenoid valve 2, water pump 4, and first spray solenoid valve 9 according to the outdoor temperature and humidity.

[0044] For example, the main control board is the EVO main control board.

[0045] In one possible embodiment, the main control board is specifically used to execute steps S1-S3, as follows: Figure 2 As shown.

[0046] Step S1: Determine whether the outdoor temperature is greater than or equal to the first temperature and whether the outdoor humidity is less than the first humidity. If not, continue with step S1; if yes, proceed to step S2.

[0047] For example, the first temperature is the spray start temperature setpoint t1 (default is 30℃).

[0048] For example, the first humidity setting is φ1 (default 80%).

[0049] In this embodiment of the present invention, if step S1 determines no, the original mode is maintained, and step S1 is continued.

[0050] Step S2: Open the water inlet solenoid valve 2.

[0051] Step S3: After the water inlet solenoid valve 2 is opened, the water pump 4 and the first spray solenoid valve 9 are turned on to make the first spray module 11 run.

[0052] In one possible embodiment, after the main control board turns on the water pump 4 and the first spray solenoid valve 9, it is further used to execute steps S4-S7, as follows: Figure 2 As shown.

[0053] Step S4: Determine whether the outdoor temperature is lower than the second temperature and whether the outdoor humidity is higher than the second humidity. If not, maintain the state after step S3; if yes, proceed to step S5.

[0054] For example, the second temperature is the setpoint t2 for the off spray temperature (default is 25°C).

[0055] For example, the second humidity shut-off spray relative humidity setpoint φ2 (default 90%).

[0056] In this embodiment of the present invention, if step S4 determines that the result is negative, the original mode is maintained and step S4 is executed again.

[0057] Step S5: Close the inlet solenoid valve 2;

[0058] Step S6: After the inlet solenoid valve 2 is closed, turn off the water pump 4;

[0059] After step S7, water pump 4 is turned off, the first spray solenoid valve 9 is turned off, and step S1 continues.

[0060] When the outdoor temperature reaches the spray activation point but the humidity is high, activating the spray results in poor evaporation, low condenser heat dissipation, and wasted water. Therefore, in this embodiment, when the outdoor temperature is lower than a second temperature and the outdoor humidity is higher than a second humidity, the inlet solenoid valve 2, water pump 4, and first spray solenoid valve 9 are closed to shut off the spray. This embodiment incorporates humidity control shutdown logic, saving water resources; it also reduces the problem of water droplets clogging the condenser fins and reducing condensation efficiency caused by prolonged spraying; and it is low-cost, requiring only the replacement of a temperature and humidity sensor and a software logic upgrade.

[0061] Optionally, such as Figure 1 As shown, the system also includes a filter 3, which is located between the inlet solenoid valve 2 and the water pump 4; after the coolant flows out of the inlet solenoid valve 2, it flows through the filter 3 and enters the water pump 4.

[0062] Optionally, such as Figure 1 As shown, the system also includes: a second spray solenoid valve 10, a second spray module 12, and a second spray outdoor unit 14; the outlet of the water pump 4 is also connected to one end of the second spray solenoid valve 10; the other end of the second spray solenoid valve 10 is connected to the inlet of the second spray module 12, and the outlet of the second spray module 12 is connected to the inlet of the second spray outdoor unit 14. After the coolant flows out from the water pump 4, it can also flow through the second spray solenoid valve 10 into the second spray module 12, and then flow out from the second spray module 12 into the second spray outdoor unit 14.

[0063] The second spray solenoid valve 10 and the second spray module 12 are electrically connected to the main control board.

[0064] In one possible embodiment, the main control board is also used to control the opening or closing of the second spray solenoid valve 10.

[0065] For example, when the water pump 4 is turned on, the second spray solenoid valve 10 is turned on to make the second spray module 12 run; after the water pump 4 is turned off, the second spray solenoid valve 10 is turned off.

[0066] Optionally, such as Figure 1 As shown, the system also includes: a pressure sensor 5, a bypass solenoid valve 6, and a bypass capillary tube 7; the pressure sensor 5 is located at the outlet of the water pump 4; the outlet of the water pump 4 is also connected to one end of the bypass solenoid valve 6, the other end of the bypass solenoid valve 6 is connected to one end of the bypass capillary tube 7, and the other end of the bypass capillary tube 7 is connected to the inlet of the water pump 4. Coolant flowing from the water pump 4 through the pressure sensor 5 can also flow into the bypass solenoid valve 6; after flowing out of the bypass solenoid valve 6, the coolant flows through the bypass capillary tube 7 and enters the water pump 4.

[0067] Among them, the pressure sensor 5 and the bypass solenoid valve 6 are electrically connected to the main control board; the main control board is also used to: when only one spray module is turned on, obtain the water pump outlet pressure collected by the pressure sensor 5, and open or close the bypass solenoid valve 6 according to the water pump outlet pressure.

[0068] For example, when the water pump outlet pressure is greater than or equal to the first pressure, the bypass solenoid valve 6 is opened; when the water pump outlet pressure is less than the second pressure, the bypass solenoid valve 6 is closed.

[0069] When a spray system contains multiple spray modules and only one spray module is activated, pressure problems may occur within the system. A pressure relief module (pressure sensor 5, bypass solenoid valve 6, bypass capillary tube 7) needs to be installed to resolve internal pressure abnormalities, ensure stable pressure within the system, and avoid affecting the spraying effect of the spray module.

[0070] Optionally, such as Figure 1 As shown, the system also includes: a drain solenoid valve 8; the drain solenoid valve 8 is located at the outlet of the water pump 4, and the coolant can flow into the drain solenoid valve 8 after flowing out of the water pump 4; the drain solenoid valve 8 is used to discharge the coolant from the drain solenoid valve 8 when the drain solenoid valve 8 is opened.

[0071] The drain solenoid valve 8 is electrically connected to the main control board; the main control board is also used to control the opening or closing of the drain solenoid valve 8 according to the outdoor temperature.

[0072] For example, when the outdoor temperature is less than or equal to the third temperature, the drain solenoid valve 8 is opened to drain the coolant.

[0073] In this embodiment of the invention, the drain solenoid valve 8 can be used for winter antifreeze drainage.

[0074] The spray cooling system provided in this embodiment of the invention, on the one hand, eliminates the need for an air compressor, using a simpler structure such as an inlet pipe and a regular water pump, thereby simplifying the structure of the spray cooling system and reducing costs. On the other hand, replacing the temperature sensor with a temperature and humidity sensor adds logic for controlling the spray on and off based on relative humidity, enhancing the water efficiency and energy conservation of the spray system. Furthermore, when multiple spray modules are set but only one is activated, it also includes a water pump outlet pressure sensor, a bypass solenoid valve, and a bypass capillary tube for bypass pressure relief, ensuring stable pressure within the system and preventing impact on the spraying effect of the spray module. Finally, the addition of a drain solenoid valve can be used for winter antifreeze drainage.

[0075] Figure 3 A schematic diagram of an air conditioning device provided for an embodiment of this utility model is shown below. Figure 3 As shown, the air conditioning equipment includes Figure 2 The spray cooling system shown is an example of an air conditioning system. Since the air conditioning equipment includes the aforementioned spray cooling system, it also has the same beneficial effects as the spray cooling system.

[0076] This utility model embodiment also provides an apparatus, including a server, and Figure 2 The device includes the aforementioned spray cooling system, and therefore has the same beneficial effects as the spray cooling system.

[0077] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
