Description

Technical Field

[0001] This disclosure relates to the field of overall energy-saving technology for site equipment, and in particular to a drainage system, a ground-source constant temperature air conditioner, and a constant temperature system. Background Technology

[0002] In the current technological landscape, with the advancement of digital construction using 5G (5th Generation Mobile Networks) technology, energy conservation, clean energy, and empowerment are the three main action lines. Site energy conservation is particularly important, as the high-density integration of communication equipment increases the temperature of equipment within the data center, making heat dissipation solutions for equipment within the site increasingly crucial.

[0003] Traditional base stations mostly use ordinary air conditioners, and the energy consumption of the air conditioning system generally accounts for about 35% to 50% of the total energy consumption of the base station. Therefore, reducing air conditioning energy consumption is a key link in achieving energy conservation and emission reduction in base station equipment rooms. Utility Model Content

[0004] This disclosure aims to at least partially address one of the technical problems in the related art.

[0005] Therefore, one objective of this disclosure is to provide a drainage system.

[0006] The second objective of this disclosure is to propose a ground-source constant temperature air conditioning system.

[0007] The third objective of this disclosure is to propose a constant temperature system.

[0008] To achieve the above objectives, the first aspect of this disclosure provides a drainage system, comprising: an inlet pipe, n U-shaped condensate pipes, and a drain pipe. The n U-shaped condensate pipes are sequentially connected by pipes and installed at the bottom or side of the rack equipment. The height of the drain pipe is less than the height of the inlet pipe. The first U-shaped condensate pipe is connected to the inlet pipe and is used to receive condensate. The height of the highest point of each subsequent U-shaped condensate pipe decreases sequentially, forming a stepped layout. The nth U-shaped condensate pipe is connected to the drain pipe and is used to discharge condensate. Here, n is a positive integer greater than or equal to 2.

[0009] According to one embodiment of this disclosure, the system further includes a booster pump, which is installed on the water inlet pipe and is used to start when the pressure value of the condensate at the inlet of the first U-shaped condensate pipe is less than a first set pressure value, so as to increase the pressure value of the condensate.

[0010] According to one embodiment of this disclosure, the system further includes a pressure-reducing pump, which is installed on the drain pipe and is activated when the pressure value of the condensate at the outlet of the nth U-shaped condensate pipe is greater than a second set pressure value, so as to reduce the pressure value of the condensate.

[0011] According to one embodiment of this disclosure, the system further includes: a pressure acquisition point and a T-type valve installed on the connecting pipe between two adjacent U-shaped condensate pipes; wherein the T-type valve is used to automatically adjust its opening degree to change the flow rate of the condensate when the pressure value of the condensate detected at the corresponding pressure acquisition point exceeds the set pressure range.

[0012] According to one embodiment of this disclosure, the system further includes: a filtration device, which is a multi-stage filter disposed on the water inlet pipe for filtering impurities in the condensate step by step; a wastewater discharge container disposed on the water inlet pipe for storing chemical substances; and a wastewater discharge valve for discharging impurities and / or chemical substances from the condensate.

[0015] According to one embodiment of this disclosure, the system further includes: at least two second water immersion sampling points, two of which are respectively located at the lowest point of the inlet of the first U-shaped condensate pipe and the lowest point of the outlet of the nth U-shaped condensate pipe, for monitoring the accumulation or leakage of condensate.

[0024] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0025] The acquisition, storage, use, and processing of data in this disclosed technical solution all comply with the relevant provisions of relevant laws and regulations.

[0026] It should be noted that in the embodiments of this application, certain software, components, models and other existing solutions in the industry may be mentioned. These should be regarded as exemplary and are only intended to illustrate the feasibility of implementing the technical solution of this application. However, it does not mean that the applicant has used or necessarily used the solution.

[0027] Figure 1 This is a schematic diagram of a drainage system according to one embodiment of the present disclosure, such as... Figure 1 As shown, the drainage system includes: an inlet pipe 110, n U-shaped condensate pipes 120, and a drain pipe 130.

[0028] In this embodiment of the disclosure, n U-shaped condensate pipes are connected in sequence and installed at the bottom or side of the rack equipment, and the height of the drain pipe is less than the height of the inlet pipe.

[0029] The first U-shaped condensate drain pipe in the n U-shaped condensate drain pipes is connected to the inlet pipe and is used to receive condensate.

[0030] In the embodiments disclosed herein, such as Figure 1 As shown, the height of the highest point of each subsequent U-shaped condensate pipe decreases sequentially, forming a stepped layout.

[0031] This design allows the preceding U-shaped condensate pipes and the following U-shaped condensate pipes to form a communicating vessel with a height difference. According to the principle of communicating vessels, the condensate from the preceding U-shaped condensate pipes will automatically flow into the following U-shaped condensate pipes. This design reduces the energy required for the condensate to flow in the U-shaped condensate pipes, thus reducing energy consumption.

[0032] The nth U-shaped condensate drain pipe is connected to the drain pipe and is used to drain the condensate.

[0033] Where n is a positive integer greater than or equal to 2.

[0034] Because the height of each U-tube decreases sequentially, the condensate cools down gradually as it flows through each U-tube, thus improving the overall condensation efficiency. The condensate can also be distributed more evenly among the multiple U-tubes, avoiding overload in individual pipe sections and ensuring that each section effectively participates in the condensation process.

[0035] This stepped layout utilizes gravity to allow condensate to flow naturally, reducing the energy required for pumping and lowering system energy consumption. The lower-positioned U-shaped pipes facilitate smooth condensate drainage, preventing water accumulation and airlocks, while also enhancing the cooling effect of the U-shaped pipes. Furthermore, the number of multi-stage U-shaped pipes can be increased or decreased according to actual operational needs, making it more practical. Experiments have shown that, compared to current U-shaped condensate piping systems, the present invention only requires 30-50% more condensate to achieve the same condensate flow rate as current U-shaped condensate piping systems (100% condensate flow rate).

[0036] In one possible implementation, the rack equipment above the n U-shaped condensate drain pipes can be distributed according to the actual heat generation of the rack equipment. The rack equipment with higher heat generation can be placed above the later U-shaped condensate drain pipes, i.e., closer to the nth U-shaped condensate drain pipe. This layout optimizes heat dissipation and ensures efficient system operation. For example, consider three rack equipment A, B, and C, with heat generation of B > A > C. In a drainage system consisting of three U-shaped condensate drain pipes, B can be placed above the third U-shaped condensate drain pipe, A above the second U-shaped condensate drain pipe, and C above the first U-shaped condensate drain pipe.

[0037] In one possible implementation, such as Figure 2 As shown, the system also includes a booster pump, which is installed on the water inlet pipe and is used to start when the pressure of the condensate at the inlet of the first U-shaped condensate pipe is less than the first set pressure value, so as to increase the pressure of the condensate.

[0038] By setting a booster pump and a first preset pressure value, it is possible to prevent low water pressure from affecting the normal operation of the drainage system. It should be noted that the first preset pressure value is pre-designed and can be changed according to actual design needs; no limitations are imposed here.

[0039] In one possible implementation, such as Figure 2 As shown, the system also includes a pressure-reducing pump, which is installed on the drain pipe and is activated when the pressure of the condensate at the outlet of the nth U-shaped condensate pipe is greater than the second set pressure value, so as to reduce the pressure of the condensate.

[0040] By setting a pressure-reducing pump and a second set pressure value, it should be noted that the second set pressure value is pre-designed and can be changed according to actual design needs; no restrictions are imposed here.

[0041] In one possible implementation, such as Figure 2 As shown, the system also includes pressure sampling points and T-valvees installed on the connecting pipes between two adjacent U-shaped condensate pipes. The T-valve automatically adjusts its opening to change the condensate flow rate when the pressure value detected at the corresponding pressure sampling point exceeds the set pressure range. This control rule can be set according to actual design needs and is not limited here. For example, when the pressure value at the pressure sampling point is within the set pressure range, the condensate will flow normally; if the pressure value at the pressure sampling point exceeds the set pressure range, the T-valve will automatically adjust the water flow to ensure stable system operation. This set pressure range can be changed according to actual design needs and is not limited here.

[0042] In one possible implementation, such as Figure 2 As shown, the system also includes a filtration device, which is a multi-stage filter installed on the inlet water pipe to filter impurities in the condensate water step by step. It should be noted that the filtration device can store detergents and other chemical materials, which can be directly injected into the condensate pipes to reduce scale formation.

[0043] In another possible implementation, a sight glass can be installed behind the filter to monitor the condensate level inside the condensate tubing in real time. A drain port is located at the bottom of the condensate inlet pipe. When the sight glass detects excessive scale buildup, the system will trigger an alarm and upload the information to a cloud platform or personal computer (PC) to notify relevant personnel for handling.

[0044] In one possible implementation, such as Figure 2 As shown, the system also includes a sludge discharge container, which is installed on the inlet water pipe and is used to store chemicals, and a sludge discharge valve, which is used to discharge impurities and / or chemicals from the condensate.

[0045] In one possible implementation, such as Figure 2 As shown, the system also includes a water storage tank for storing a portion of the condensate discharged from the drainage pipes for reuse, a booster pump, and a spray system. The booster pump supplies another portion of the condensate discharged from the drainage pipes to the spray system.

[0046] In one possible implementation, the system also includes multiple trays, each installed at the intersection of the air outlet of the rack equipment and the connecting pipe between two adjacent U-shaped pipes, and equipped with at least one first water immersion sampling point for monitoring condensate leakage.

[0047] In one possible implementation, such as Figure 2 As shown, the system also includes at least one second water immersion sampling point, which is set at the lowest point of the inlet of the first U-shaped condensate pipe and the lowest point of the outlet of the nth U-shaped condensate pipe, respectively, to monitor the accumulation or leakage of condensate.

[0048] It should be noted that sensors can be installed at the first and second water immersion sampling points to monitor for cold water leaks.

[0049] Figure 3 This is a schematic diagram of a ground-source constant temperature air conditioner according to one embodiment of this disclosure, as shown below. Figure 3As shown, the ground-source constant temperature air conditioning system includes at least one drainage system. The drainage system is as follows: Figures 1-2 The drainage system shown in the embodiment.

[0050] Figure 4 This is a schematic diagram of a constant temperature system according to one embodiment of the present disclosure, such as... Figure 4 As shown, the constant temperature system includes a ground source constant temperature air conditioner, which is as follows: Figure 3 The air conditioner shown in the example.

[0051] In this embodiment, a constant temperature system can be introduced into the operator's site, which can be a core data center or other similar facility. The application cloud platform, through machine interconnection, rationally introduces the constant temperature system within the site and activates the ground-source constant temperature air conditioning system according to cooling needs. A unified overall gaseous and liquid refrigeration cycle is formed within the site and around the equipment. The circulating refrigeration structure system is managed, and the water-cooled physical pressure difference using composite stepped U-shaped pipes balances the equipment load, avoiding localized heat island effects. This prevents potential hazards caused by water seepage at condenser pipe nodes or outside the equipment.

[0052] In one possible implementation, such as Figure 5 As shown, Figure 5 This is a schematic diagram of the station arrangement of a constant temperature system according to one embodiment of the present disclosure. The station arrangement of the constant temperature system can be as follows: Figure 5 As shown, it includes solar-assisted energy (1), controller (2), constant temperature fresh air system (3), which includes main air intake regulating pipe and main air outlet regulating pipe, ground source constant source air conditioner (4), PE heat exchange pipe (5), cloud platform (6), branch air intake pipe (7), branch air outlet pipe (8), air volume detector (9), composite stepped U-shaped condensate pipe (10), booster pump (11), depressurization pump (12), booster pump (13), outdoor sprinkler (14), temperature or infrared sensor (15), wet bulb detector (16), filter (17), water storage tank (18), sight glass (19), tray (20), maintenance monitoring point (21), first water immersion collection point (22), and second water immersion collection point (23).

[0053] The solar-assisted power supply (1), controller (2), and ground-source constant-source air conditioning (4) are connected to the existing AC power distribution panel of the site. The existing switching power supply provides DC power for control signals to the controller (2). The battery ensures the normal operation of the system in the event of a mains power outage. The controller (2) communicates with the cloud platform (6) via IP protocol and uploads data to the cloud platform (6). The cloud platform (6) has storage and analysis functions and supports access and operation via PC.

[0054] The controller (2) can collect the equipment temperature and ambient temperature throughout the site. The controller (2) includes components such as a control chip and temperature sensors, and communicates with the temperature acquisition unit / infrared temperature detector (15). The temperature acquisition unit / infrared temperature detector (15) is used to collect temperature information within the equipment and local areas of the site, and feeds this data back to the cloud platform (6). After analyzing the data, the cloud platform (6) will issue alarm commands if necessary. In addition, the controller (2) can detect the overall ambient temperature of the site through the temperature or infrared sensor (15) to ensure the stable operation of the system.

[0055] The system first establishes a unified overall cooling cycle within the site and around the equipment, achieving efficient heat removal through physical connections. Specifically, it may include temperature and humidity monitoring, using an airflow meter (9), a temperature or infrared sensor (15), and a wet-bulb meter (16) to monitor environmental conditions in real time.

[0056] Water treatment and filtration: Water filters (17) ensure clean water and prevent impurities from entering the system;

[0057] Airflow circulation: The constant temperature system (3) and the ground source constant temperature air conditioner (4) are connected as a whole through the air inlet and outlet pipes and the main air outlet regulating pipe to form an overall airflow circulation structure within the site;

[0058] Local airflow management: Each rack is equipped with a branch air inlet duct (7) to optimize local airflow distribution.

[0059] Condensate management: A composite stepped U-shaped condensate pipeline (10) is used to effectively collect and discharge condensate.

[0060] Drainage system: A drainage pipeline consisting of a composite stepped U-shaped condensate pipe (10), a booster pump (11), a depressurization pump (12), a booster pump (13), an outdoor sprinkler system (14), and a water filter (17) is installed around the equipment frame to ensure the stable operation of the system.

[0061] To effectively detect and prevent leaks, detection devices are installed at the highest and lowest points of the composite stepped U-shaped pipe (10). Furthermore, anti-leakage trays (24) are installed at the intersections of the rack and condensate pipes. These trays include at least one first water immersion sampling point (26), and a first water immersion alarm is installed on the tray at the intersection of the rack and condensate pipe for real-time monitoring of potential leaks. For more concealed leak risks, second water immersion sampling points (27) are set at the lowest points of the first U-shaped condensate pipe inlet and the nth U-shaped condensate pipe outlet to monitor condensate accumulation or leakage. These locations are considered critical areas prone to water accumulation or leakage, and the installation of second water immersion sampling points (27) enhances system safety. Once water intrusion is detected, the water immersion sampling point immediately transmits an alarm signal to the controller, and the information is then sent to the cloud terminal (6). This design not only improves the response speed to emergencies but also ensures that maintenance personnel can take timely action to avoid potential losses.

[0062] In one possible implementation, the system collects heat generation data via sensors based on the power of each rack unit and transmits the data to the controller (2). The controller (2) issues instructions to the fresh air system (3) based on this information and adjusts the airflow through the airflow detector (9). The branch duct (7) ensures the separation of hot and cold airflow and increases the airflow circulation, achieving precise airflow to the relevant equipment and effectively removing excess heat. Based on the heat generation of different equipment, the system can adjust the airflow through duct circulation to achieve the best cooling effect.

[0063] When the temperature or infrared sensor (15) detects that the ambient temperature is higher than the normal operating temperature of the equipment, the ground source constant temperature air conditioner (4) will be started. At this time, the booster pump (11) will transport water through the composite stepped U-shaped condensate pipe (10) to the filter (17) for filtration of impurities. After that, the filtered cold water medium enters the coil of the indoor rack circulation to remove the heat generated by the indoor rack equipment. Excess water goes to the drain pipe through the depressurization pump (12), while most of the water is supplied to the air conditioner outdoor unit spray equipment (14) through the outdoor booster pump (13). The remaining water flows into the water storage tank (18) for reuse.

[0064] To avoid the impact of excessively high or low humidity on the equipment, the system uses a wet-bulb meter (16) to monitor humidity levels. Different pipeline control strategies can be used to achieve independent circulation of the medium water and air, thereby addressing heat dissipation issues in the site's interior and around the equipment racks, especially in areas with localized high temperatures. Under specific conditions, such as when the local temperature at the site is high, air ducts and drainage pipes can be activated simultaneously to provide additional cooling support.

[0065] This design not only improves cooling efficiency but also ensures safe operation of the equipment and achieves efficient energy utilization through effective management of temperature, humidity, and airflow. Furthermore, the system's flexibility and intelligent features greatly enhance its ability to cope with various environmental changes.

[0066] In this embodiment, a solar auxiliary energy source (1) can be introduced from outside the site, with a total power output that meets the power requirements of the equipment inside the site. It can be used independently as a power source or combined with a generator to form a hybrid power generation system. When the mains power is abnormal or there is a power outage, it can automatically switch to off-grid operation mode. Weather information is obtained through the cloud platform (6), and the sensor identifies the outdoor temperature. When the site temperature is below 25 degrees Celsius, the constant temperature and humidity fresh air system (3) is prioritized to optimize airflow organization, clear the air conditioning ducts, and accelerate the heat exchange of the air conditioning system.

[0067] In another possible implementation, the controller can also distribute the site's energy. Weather information is obtained through the cloud platform (6). During normal weather, solar renewable energy combined with battery pack peak shaving and valley filling technology automatically charges and discharges the batteries according to the peak and off-peak periods of the power grid, achieving peak shaving and valley filling to save electricity costs. The system automatically switches back to operating status through the controller (2). The backup power time and backup power capacity can be set and adjusted according to different loads. The cloud platform (6) completes the peak-shaving control management of the charging and discharging of the batteries. In case of abnormal weather, the controller (2) issues an instruction for priority power supply from the mains power grid.

[0068] The controller (2) can also upload data to the cloud platform (6) to provide feedback on the airflow organization of the site, and to determine the cooling effect of the air conditioner and the supply and return air conditions of each vent. This optimizes the airflow organization, clears the air conditioning ducts, and accelerates the heat exchange of the air conditioning system.

[0069] The site is equipped with air ducts, condensate pipes, and a constant temperature and humidity fresh air system (3). Based on the interaction between the natural evaporation of water and the evaporative cooling of the air conditioning system, the return air regulating pipe and the outlet air regulating pipe form a constant temperature and humidity system for overall air conditioning circulation within the site. Air ducts are installed inside the walls and condensate channels are set around the rack. Fan coil units are installed on the top. Booster pumps and debooster pumps are installed on both sides and connected to the ground source constant temperature air conditioning. According to the priority level of the sensor temperature change, the fresh air system is started first. When the outdoor temperature is greater than 28 degrees Celsius, the ground source constant temperature air conditioning (4) is started. The filtered water is circulated to the indoor circulation coil through the boost pump (11) and condensate pipe. The excess water is circulated to the drain pipe through the debooster pump (12) and enters the water storage tank (18) for recirculation. In order to avoid excessive or low humidity, the detection equipment samples the wet bulb temperature and sets the measurement point. According to the set index, the controller (2) automatically adjusts the fan air volume or the water volume of the ground source constant temperature air conditioning pipe. Because it has different piping systems, it can achieve independent or simultaneous circulation of water and air. This solves the heat dissipation problem in the site and around the equipment racks, and resolves the issue of localized high temperatures in the equipment.

[0070] The cooling system within the site utilizes a ground-source constant temperature air conditioner (4) and a high-efficiency heat exchange device (5) to input a small amount of high-grade energy (such as electricity), allowing the transfer of energy at different temperature levels in the two environments to converge towards a consistent temperature. This achieves a constant indoor temperature, maintaining consistency with the ground. Since the water temperature detected by the ground-source constant temperature air conditioner (4) is 15 degrees Celsius, the heat is less than the temperature within the site and the local temperature of the equipment. The controller (2) issues relevant instructions to activate the air conditioner (4). Pressure is provided by a booster pump (11) and a depressurization pump (12), and a composite stepped U-shaped pipeline (10) is used to achieve the passage of the condensate medium, thus removing local heat. As a result, a unified circulation system is formed within the site and around the equipment rack through different pipelines, using the 15-degree Celsius condensate from the ground-source constant temperature air conditioner to remove excess heat from the site and equipment rack. Condensate water paths and air ducts are provided around the rack. According to different thresholds, the controller issues instructions to activate fresh air to different equipment rack ends, without forming airflow within the rack. When the temperature exceeds 28 degrees Celsius, the condensate circulates to remove localized heat from the equipment within the rack. Automatic switching between air and water media is possible. Both modes can also be activated simultaneously.

[0071] In terms of airflow organization, the system predicts airflow within the site and accurately estimates local hotspots in the server racks. Temperature and humidity sensors monitor indicators in real time at the system's air inlet and outlet to prevent airflow from atomizing to a critical point and forming water mist that could affect the equipment.

[0072] The constant-temperature system sites deployed in this disclosure can utilize photovoltaics, constant-temperature ground source heat pumps, etc., for energy storage and for power supply or cooling applications. Distributed photovoltaic systems combined with peak shaving and valley filling technologies achieve energy conservation. The system can be automatically switched via controllers, reducing the time and frequency of manual on-site power generation and improving work efficiency.
