Description

Technical Field

[0001] The present invention relates to the field of heat dissipation equipment for data computer rooms, and particularly to an energy-saving special-purpose air conditioner for communication data computer rooms. Background Art

[0002] With the rapid development of information technology, the scale and density of communication data computer rooms are constantly increasing. A large number of servers, network devices, etc. in the computer room run continuously, generating high amounts of heat. If heat cannot be dissipated in a timely and effective manner, it will cause the equipment to overheat, which will in turn lead to serious problems such as a decline in equipment performance, an increase in failures, and even hardware damage, seriously affecting the stability and reliability of communication data services.

[0003] Traditional computer room air conditioners often have many deficiencies during the refrigeration process. On the one hand, their energy consumption is relatively high. Most ordinary computer room air conditioners adopt relatively fixed refrigeration modes and control strategies, and cannot accurately adjust the refrigeration capacity according to the actual heat load changes in the computer room, often resulting in over-refrigeration and causing a large amount of energy waste. For example, during periods when the load of the computer room equipment is low, the air conditioner still operates at full load or a relatively high load, consuming a large amount of unnecessary electric energy.

[0004] On the other hand, the heat dissipation uniformity of traditional computer room air conditioners is poor. In the air supply process of some air conditioning systems, cold air cannot be reasonably distributed, resulting in too low temperature in local areas of the computer room, while other areas may not be sufficiently cooled, with local hot spots, which is extremely unfavorable for the long-term stable operation of precision equipment in the computer room and easily leads to problems such as aging and failures of the equipment due to uneven temperature.

[0005] Furthermore, traditional air conditioners are lacking in utilizing natural environmental conditions to assist in cooling. During periods when the temperature difference between day and night is large or the external environmental temperature is suitable, they fail to make full use of external cold air or other natural cold sources (such as heat absorption by water evaporation, etc.) to reduce the temperature of the computer room, and only rely on the mechanical refrigeration of the refrigeration unit, further increasing energy consumption.

[0006] In addition, the intelligent management and operation and maintenance level of the computer room air conditioning system also needs to be improved. There is a lack of a perfect equipment operation status monitoring and evaluation system, and potential equipment failures cannot be discovered and warned in a timely and accurate manner. At the same time, data management and analysis are not fine enough, and it is difficult to make intelligent decisions based on multi-dimensional data of the computer room environment and equipment operation to optimize the operation efficiency and energy-saving effect of the air conditioning system. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides an energy-saving special-purpose air conditioner for communication data computer rooms, which solves the problems of high heat dissipation energy consumption, uneven heat dissipation, inability to effectively utilize natural cold sources, and insufficient intelligent management and operation and maintenance in communication data computer rooms.

[0016] The present invention provides an energy-saving special air conditioner for a communication data room. It has the following beneficial effects:

[0017] 1. The present invention separates the wind channel and the water channel by arranging heat exchange plates in the coil pipe, so that the air in the computer room can fully exchange heat with the condensed water generated by the refrigeration unit and the heat exchange plates, effectively converting hot air into cold air, thereby enhancing the heat dissipation and cooling effect.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment:

[0031] Please refer to the attached Figure 1 - attached Figure 7 , the embodiment of the present invention provides an energy-saving special-purpose air conditioner for a communication data computer room, such as Figure 1As shown in the figure, it includes a refrigeration unit 1. As the core refrigeration component of the entire air conditioning system, components such as the compressor, condenser, and evaporator inside the refrigeration unit 1 work together to transfer and dissipate heat through the circulation of the refrigerant, thereby providing a refrigeration effect for the data room. On one side of the refrigeration unit 1, there is a coiled air duct 2. The coiled air duct 2 is designed with special materials and structures, having good sealing and heat insulation properties to reduce heat loss and external interference. Inside the coiled air duct 2, several heat exchange plates 3 are evenly and fixedly installed. These heat exchange plates 3 are usually made of metal materials with high thermal conductivity, such as aluminum alloy, etc., and their surfaces are specially treated to enhance the heat exchange efficiency. The inside of the coiled air duct 2 is divided into several air flow channels 4 and water flow channels 5 by the heat exchange plates 3. The air flow channel 4 is the circulation path of the air in the computer room. On the upper and lower sides inside it, there are guide vanes 6 fixedly installed. The shape and angle of the guide vanes 6 are carefully designed to be able to guide the air to form a stable and uniform air flow in the air flow channel 4, reducing the resistance and turbulent flow phenomenon of air flow, so that the air can fully contact and exchange heat with the heat exchange plates 3 and the water in the water flow channel 5. The top of the water flow channel 5 is connected to the water outlet end of the external unit of the refrigeration unit 1, so that the condensed water generated during the refrigeration process of the refrigeration unit 1 can smoothly flow into the water flow channel 5 for storage. At the bottom end of the water flow channel 5, there is a drain pipe 26 fixedly installed. An electromagnetic valve 27 is fixedly installed on the outer diameter of the drain pipe 26. The electromagnetic valve 27 can accurately control the discharge and flow regulation of the water in the water flow channel 5.

[0032] In this embodiment, an air inlet 7 is provided on one side of the coiled air duct 2. The position and size of the air inlet 7 are optimized to facilitate the smooth entry of the air in the computer room into the air flow channel 4 of the coiled air duct 2. An air outlet 8 is provided on the other side of the coiled air duct 2. The air outlet 8 is closely connected to the exhaust duct 9. The exhaust duct 9 is fixedly installed at the end of the air outlet 8 and the exhaust duct 9 extends into the computer room. A number of exhaust ports 10 are evenly opened on the bottom of the exhaust duct 9. The distribution of these exhaust ports 10 is uniform, and the processed cold air can be evenly delivered to each area of the computer room. At the position near each exhaust port 10 on one side inside the exhaust duct 9, there is a flow splitting blade 11 fixedly connected, and the width of the flow splitting blade 11 increases sequentially from the inside to the outside. The unique design of the flow splitting blade 11 can effectively distribute the cold air evenly into each exhaust port 10 according to the flow characteristics of the cold air, avoiding the situation of excessive or insufficient local air volume, thereby improving the uniformity of heat dissipation in the computer room. At the position near each exhaust port 10 at the bottom end of the exhaust duct 9, there is a venturi tube 12 fixedly connected. When the cold air enters the venturi tube 12 at the bottom of the exhaust port 10, due to the special structure of the venturi tube 12, the pressure of the air will increase when it flows through it. According to Bernoulli's principle, the speed of the air will increase, and during the process of the air speed increasing, its own temperature will further decrease, thus achieving better cooling and heat dissipation work in the computer room.

[0033] Specifically, four exhaust ports 10 are provided in this embodiment. Then the widths of the diversion vanes 11 from left to right are successively 1 / 4, 1 / 3, 1 / 2, and 1 of the width of the exhaust port 10. At the same time, N exhaust ports 10 can also be set as required. Then the widths of the diversion vanes 11 from left to right are successively 1 / N, 1 / (N - 1),...., 1 / 2, and 1 of the width of the exhaust port 10, which can ensure that the exhaust air volume of each exhaust port 10 is the same and improve the uniformity of heat dissipation.

[0034] Further, a control box 13 is fixedly installed on one side of the coil air duct 2. The control box 13 plays a role in centralized control and adjustment. A blower 14 is fixedly installed on one side inside the control box 13. The blower 14 is driven by an energy-efficient motor and can generate sufficient air pressure and air volume to introduce the air inside or outside the computer room into the control box 13. A desiccant rack 15 is fixedly installed on the other side inside the control box 13. High-quality desiccants such as silica gel and molecular sieve are placed on the desiccant rack 15, which can effectively adsorb the moisture in the air and prevent the humid air from entering the computer room or participating in the heat exchange process and causing adverse effects on the equipment. An air outlet pipe 19 is fixedly installed at one end of the control box 13 close to the coil air duct 2, and the end of the air outlet pipe 19 is connected to the inside of the air inlet 7. A branch pipe 20 is also fixedly installed at the bottom of the air outlet pipe 19, and the end of the branch pipe 20 is connected to the inside of one side of the exhaust air duct 9. A reversing valve 21 is fixedly installed at the connection between the air outlet pipe 19 and the branch pipe 20. The reversing valve 21 can flexibly switch the air flow direction and guide the air to flow along a predetermined path under different working modes. A housing 22 is fixedly installed above the middle of the branch pipe 20. The housing 22 provides an installation and protection space for components such as a hollow rotating shaft 23. A hollow rotating shaft 23 is movably installed inside the housing 22, and the top of the hollow rotating shaft 23 is connected to the bottom end of the down pipe 26. A driven bevel gear 28 is fixedly installed on the outer diameter of the middle part of the hollow rotating shaft 23. A motor 29 is fixedly installed on one side of the housing 22. The driving end of the motor 29 extends into the inside of the housing 22 and is fixedly installed with a driving bevel gear 30, and the driving bevel gear 30 is meshed with the inner end of the driven bevel gear 28. By driving the driving bevel gear 30 to rotate by the motor 29, the driven bevel gear 28 and the hollow rotating shaft 23 are driven to rotate at high speed through gear meshing transmission, so as to drive the cross brush plate 25 to rotate at high speed. A water inlet chamber 24 is opened at the inner bottom of the housing 22. The bottom end of the hollow rotating shaft 23 extends into the inside of the water inlet chamber 24 and is fixedly installed with a cross brush plate 25. The cross brush plate 25 rotating at high speed will disperse the water flow entering the water inlet chamber 24 into fine water droplets. These fine water droplets are mixed with the outside air to form a high-speed water-vapor fluid, and finally enter the computer room through the branch pipe 20 and the exhaust air duct 9. The water-vapor fluid entering the computer room will quickly evaporate, and by using the principle of heat absorption during evaporation, it can quickly absorb the indoor heat, thereby achieving the effect of reducing the indoor temperature.

[0035] Further, on one side of one end of the control box 13 away from the disc air duct 2, a first air inlet pipe 16 is fixedly installed. The first air inlet pipe 16 is used to introduce air from outside the computer room. On the other side of one end of the control box 13 away from the disc air duct 2, a second air inlet pipe 17 is fixedly installed and the end of the second air inlet pipe 17 extends into the computer room. The second air inlet pipe 17 is used to introduce hot air inside the computer room. Switch valves 18 are fixedly installed on the outer diameters of the first air inlet pipe 16 and the second air inlet pipe 17. The switch valves 18 can conveniently control the opening and closing of the air inlet pipes, realizing the switching of the air source under different working modes. In the middle of the refrigeration unit 1, a sensor module 31 is fixedly installed. The sensor module 31 includes a temperature sensor, a humidity sensor and a light intensity sensor. The temperature sensor can accurately sense the temperature change inside the computer room. The humidity sensor can monitor the humidity of the air. The light intensity sensor can be used to sense environmental parameters such as the light intensity inside the computer room. The data collected by these sensors will be fed back to the decision-making platform in real time.

[0036] Further, it also includes an environmental monitoring platform and a decision-making platform. The environmental monitoring platform includes an equipment layer and a control layer. The equipment layer includes a refrigeration unit 1, a reversing valve 21, a switch valve 18, a fan 14, a motor 29 and a sensor module 31. The control layer includes a first computer room temperature control module, a second computer room temperature control module and a computer room environment measurement module. The refrigeration unit 1 is communicatively connected to the first computer room temperature control module. Through this communication connection, the first computer room temperature control module can obtain the operation status information of the refrigeration unit 1 and control and adjust parameters such as the refrigeration power of the refrigeration unit 1 according to the temperature requirement of the computer room. The reversing valve 21, the switch valve 18, the fan 14 and the motor 29 are communicatively connected to the second computer room temperature control module. The second computer room temperature control module can control operations such as the switching direction of the reversing valve 21, the opening and closing state of the switch valve 18, the rotation speed of the fan 14 and the start and stop of the motor 29 according to the actual heat dissipation requirement of the computer room. The sensor module 31 is communicatively connected to the computer room environment measurement module. The computer room environment measurement module receives data such as temperature, humidity and light intensity collected by the sensor module 31 and analyzes and evaluates the overall environmental condition of the computer room.

[0037] Furthermore, the decision-making platform includes a data management layer and an operation and maintenance management layer. The data management layer includes a data reception module, a data classification and storage module, and a data fusion module. The data classification and storage module includes a distributed relational database, a distributed non-relational database, and a PI database. Different types of databases are classified and stored according to the characteristics and uses of the data. For example, temperature data, humidity data, etc. can be stored in different databases respectively to facilitate data management and query. The data fusion module includes a data screening unit, a data conversion unit, and a mapping and fusion unit. The data screening unit can screen the massive data collected, removing invalid or redundant data. The data conversion unit uniformly converts data in different formats into a format convenient for analysis and processing. The mapping and fusion unit then fuses and integrates the processed data to provide comprehensive and accurate data support for subsequent equipment control and environmental regulation. The operation and maintenance management platform includes an equipment management module, an evaluation module, and a visualization display module. The equipment management module includes an equipment operation status monitoring unit and an equipment failure warning unit. The equipment operation status monitoring unit obtains the operation parameters of the equipment in real time through communication connections with each equipment, such as the rotation speed of the fan 14, the refrigeration capacity of the refrigeration unit 1, etc. The equipment failure warning unit then issues a failure warning message in a timely manner according to the preset failure threshold when the equipment operation parameters exceed the normal range, so that the operation and maintenance personnel can handle it in a timely manner. The evaluation module includes an operation status evaluation unit, a reliability evaluation unit, and an operation efficiency evaluation unit. The operation status evaluation unit comprehensively evaluates the current operation status of the equipment. The reliability evaluation unit analyzes the reliability indicators of the equipment during long-term operation. The operation efficiency evaluation unit calculates the operation efficiency of the equipment to provide a basis for equipment optimization and upgrade. The visualization display module displays information such as the operation status of the equipment and the environmental parameters of the computer room in the form of intuitive charts, graphs, etc., facilitating the operation and maintenance personnel and the computer room management personnel to quickly understand the overall situation of the system.

[0038] Working principle: During the day, when the outside temperature is high, the refrigeration unit 1 is used to dissipate heat in the data center. After the refrigeration unit 1 is started, the refrigerant circulates inside it, absorbs the heat in the data center and dissipates the heat to the outside environment. At the same time, the condensed water generated during refrigeration flows into the water flow channel 5 of the coil duct 2 through the external unit for storage. At this time, the fan 14 in the control box 13 and the switch valve 18 of the second air inlet pipe 17 are opened, and the fan 14 starts to run, and the hot air in the data center is introduced into the control box 13 through the second air inlet pipe 17. When the hot air passes through the desiccant rack 15 in the control box 13, the desiccant on the desiccant rack 15 absorbs moisture in the air and dries the air. The dried air is introduced into the air flow channel 4 in the coil duct 2 through the air outlet pipe 19 and the air inlet 7. The air in the data center is fully heat-exchanged with the condensed water in the water flow channel 5 and the heat exchange plate 3 in the air flow channel 4 to become cold air. The cold air enters the exhaust duct 9 through the air outlet 8 under the action of the fan 14, and the cold air in the exhaust duct 9 The air will be intercepted by the diverter blade 11 and discharged from the exhaust port 10 into the computer room for cooling according to the guidance of the diverter blade 11. Since the width of the diverter blade 11 increases from right to left, it can ensure that the cold air enters each exhaust port 10 evenly, thereby improving the uniformity of heat dissipation in the computer room. At the same time, when the cold air enters the venturi 12 at the bottom of the exhaust port 10, the pressure will increase, resulting in an increase in speed and further reduction in temperature, thereby achieving better cooling and heat dissipation in the computer room. In this process, the temperature sensor in the sensor module 31 will sense the temperature inside the computer room in real time and feed it back to the decision-making platform. The data management layer in the decision-making platform will analyze and manage the temperature data of the computer room and then feed it back to the environmental monitoring platform. The control layer in the environmental monitoring platform will adjust the output power of the refrigeration unit 1 in real time according to the feedback data, thereby achieving the purpose of energy saving. For example, when the temperature of the computer room gradually decreases and approaches the set suitable temperature range, the control layer of the environmental monitoring platform will instruct the refrigeration unit 1 to reduce the cooling power and reduce energy consumption.

[0039] At night, the temperature outside the computer room drops. At this time, close the switching valve 18 of the second air inlet pipe 17 and open the switching valve 18 of the first air inlet pipe 16. Introduce the air outside the computer room into the control box 13 through the first air inlet pipe 16. After the outside air enters the control box 13, it is also dried by the desiccant rack 15 and then discharged through the air outlet pipe 19. At this time, open the reversing valve 21, and the outside air will enter the branch pipe 20. At the same time, open the solenoid valve 27 on the water pipe 26. The water in the coil air duct 2 will enter the hollow rotating shaft 23 through the water pipe 26 and finally enter the water inlet chamber 24. At this time, turn on the motor 29. The motor 29 drives the driving bevel gear 30 to rotate. The rotating driving bevel gear 30 drives the driven bevel gear 28 and the hollow rotating shaft 23 to rotate at high speed through meshing transmission, thereby driving the cross brush plate 25 to rotate at high speed. The cross brush plate 25 rotating at high speed will disperse the water flow entering the water inlet chamber 24 into fine water droplets. These fine water droplets are mixed with the outside air to form a high-speed water-vapor fluid, and finally enter the computer room through the branch pipe 20 and the exhaust duct 9. The water-vapor fluid entering the computer room will quickly evaporate. Using the principle of heat absorption during evaporation, it quickly absorbs the indoor heat, thereby achieving the effect of reducing the indoor temperature and realizing the night cooling work of the computer room. During the night cooling process, the decision-making platform and the environmental monitoring platform further reduce the power of the refrigeration unit 1 according to the data fed back by the sensor module 31 to achieve the purpose of energy conservation. For example, if the computer room temperature can be maintained within a suitable range through water-vapor evaporation cooling at night, the decision-making platform can instruct the refrigeration unit 1 to suspend operation or reduce it to an extremely low power operation state to reduce unnecessary energy consumption.
