Description

数据中心的二维动态送风节能系统及其控制方法Two-dimensional dynamic air supply energy-saving system of data center and control method thereof 技术领域Technical field
本发明涉及散热技术领域,尤其涉及一种数据中心的二维动态送风节能系统及其控制方法。The invention relates to the technical field of heat dissipation, in particular to a two-dimensional dynamic air supply energy-saving system of a data center and a control method thereof.
背景技术Background technique
数据中心空调系统的主要任务是为数据处理设备提供合适的工作环境(温度、湿度、含尘度等),保证数据通信设备运行的可靠性和有效性。The main task of the data center air conditioning system is to provide a suitable working environment (temperature, humidity, dust, etc.) for the data processing equipment to ensure the reliability and effectiveness of the operation of the data communication equipment.
现有的一种数据中心的全封闭冷热隔离的空调系统,如图1所示,其包括相邻设置的第一室内空间1和第二室内空间2,机柜本体安置于第一室内空间1,制冷器3安置于第二室内空间2。这样,制冷器3在另外一房间放置,使得对制冷器3进行维修和保养时,尽量不影响机柜本体内部的设备。第一室内空间1和第二室内空间2均具有建筑地板,在建筑地板上方设有架空地板4,建筑地板和架空地板4之间形成架空空间,架空空间主要用于容纳线缆或者管道,冷风通过架空空间从制冷器送至机柜本体内,在此,架空空间可以理解为送风风道。机柜本体放置于架空地板上,机柜本体为整体封闭的,机柜本体的侧面为不透气的金属板,前面和后面为不透气的金属板或者玻璃板,机柜本体的顶面和底面及两侧留有可灵活选择的冷风入口、热风出口和线缆口等,这些都要求进行闭封。An existing fully enclosed cold and heat isolated air conditioning system of a data center, as shown in FIG. 1 , includes a first indoor space 1 and a second indoor space 2 disposed adjacent to each other, and the cabinet body is disposed in the first indoor space 1 The refrigerator 3 is disposed in the second indoor space 2. Thus, the refrigerator 3 is placed in another room so that the equipment inside the cabinet body is not affected as much as possible when the refrigerator 3 is repaired and maintained. The first indoor space 1 and the second indoor space 2 each have a building floor, and an overhead floor 4 is arranged above the building floor, and an overhead space is formed between the building floor and the raised floor 4, and the overhead space is mainly used for accommodating cables or pipes, cold air It is sent from the refrigerator to the cabinet body through the overhead space, where the overhead space can be understood as the air supply duct. The cabinet body is placed on the raised floor. The cabinet body is completely enclosed. The side of the cabinet body is a gas-tight metal plate. The front and back are airtight metal plates or glass plates. The top and bottom surfaces of the cabinet body and the two sides remain. There are flexible cold air inlets, hot air outlets and cable outlets, all of which require sealing.
请继续参阅图1,其有三个机柜本体,分别命名为第一机柜本体7、第二机柜本体8和第三机柜本体9。第一机柜本体7为单独放置,第二机柜本体8和第三机柜本体9为相邻组合放置。第一机柜本体7、第二机柜本体8和第三机柜本体9都为封闭空间,各自均具有送风区域A、热交换区域B和回风区域C,热交换区域B位于送风区域A和回风区域C之间。架空地 板4上设有多个通孔,针对第一机柜本体7,送风风道5经由通孔连通至机柜本体的送风冷区域。Please refer to FIG. 1 , which has three cabinet bodies, which are respectively named as the first cabinet body 7 , the second cabinet body 8 and the third cabinet body 9 . The first cabinet body 7 is separately placed, and the second cabinet body 8 and the third cabinet body 9 are placed in an adjacent combination. The first cabinet body 7, the second cabinet body 8, and the third cabinet body 9 are all enclosed spaces, each having a supply air area A, a heat exchange area B, and a return air area C, and the heat exchange area B is located in the air supply area A and Between the return air areas C. Overhead land The plate 4 is provided with a plurality of through holes. For the first cabinet body 7, the air supply duct 5 is connected to the air-cooling area of the cabinet body via the through holes.
上述全封闭冷热隔离的空调系统能够在一定程度上提高热交换效率,降低空调的负荷。然而其仍然存在一定的不足:The above-mentioned fully enclosed cold and heat isolated air conditioning system can improve the heat exchange efficiency to a certain extent and reduce the load of the air conditioner. However, it still has certain shortcomings:
而现有的送风均是垂直不可变风量送入到共通风道中,然后,共通风道的气流再由送风区域的侧面设置的导流孔进入所述送风区域。热交换区域B内放置的若干设备(如服务器),其热负荷、工作时所需温度不尽相同;因此,对于每一设备而言,满足其工作需要的送风量也有所不同:假设设备A1所需要风量M1,设备A2所需要风量M2,设备A3所需要风量M3;且M1>M2>M3,则如果要满足每一设备的工作需要,则需要送风量为M1,而此时,对于设备A2和A3而言,其送风量超过其工作需要,因此,整个空调系统的送冷利用效率不高,存在一定的浪费。However, the existing air supply is sent to the common air passage by the vertical immutable air volume, and then the air flow of the common air passage is further entered into the air supply area by the air guiding hole provided at the side of the air supply area. Several devices (such as servers) placed in the hot swap area B have different heat loads and temperatures required for operation; therefore, for each device, the amount of air supplied to meet their work needs is different: The air volume M1 required by A1, the air volume M2 required by equipment A2, and the air volume M3 required by equipment A3; and M1>M2>M3, if the working needs of each equipment are to be met, the air supply volume is required to be M1, and at this time, For equipment A2 and A3, the air supply capacity exceeds the working requirements. Therefore, the cooling and utilization efficiency of the entire air conditioning system is not high, and there is a certain waste.
有鉴于此,现有技术有待改进和提高。In view of this, the prior art needs to be improved and improved.

具体来说,所述分区模块100用于根据热交换区域的设备数量及热负荷在垂直方向上将送风区域分为至少二子送风单元,并在回风区域对应设置子回风单元。因为热交换区域的设备数量为多个,且每一设备的热负荷、工作温度不尽相同。在本实施例中,我们根据设备的工作温度来划分送风区域,比如由上至下依次包括设备A1、设备A2、设备B1、设备B2和设备C,且设备A1、A2的工作温度相同,设备B1、设备B2的工作温度相同,设备C的工作温度相同,则我们可以将整个送风区域在垂直方向上划分为三个子区域,即子送风单元:第一子区域送风单元对应设备A1、A2;第二子区域送风单元对应设备B1、B2,第三子区域送风单元对应设备C。当然,我们也可以等体积划分送风区域。其分区域方法为多种,这里就不 一一赘述了。同理,我们对应每一送风区域划分出相应的回风区域。Specifically, the partition module 100 is configured to divide the air supply area into at least two air supply units in a vertical direction according to the number of devices in the heat exchange area and the heat load, and to set the sub air return unit in the return air area. Because the number of devices in the heat exchange area is multiple, and the heat load and operating temperature of each device are different. In this embodiment, we divide the air supply area according to the operating temperature of the device, for example, from top to bottom, including device A1, device A2, device B1, device B2, and device C, and the operating temperatures of devices A1 and A2 are the same. The working temperature of the device B1 and the device B2 are the same, and the working temperature of the device C is the same. Then, the entire air supply area can be divided into three sub-areas in the vertical direction, that is, the sub-air supply unit: the first sub-area air supply unit corresponding device A1, A2; the second sub-area air supply unit corresponds to the devices B1, B2, and the third sub-area air supply unit corresponds to the device C. Of course, we can also divide the air supply area by the same volume. There are many sub-regional methods, so here is not One by one. In the same way, we divide the corresponding return air area for each air supply area.
所述采集模块200用于实时采集子送风单元和子回风单元的温度、热交换区域的设备热负荷,并将采集数据发送到下述的处理模块300。具体来说,可以在送风区域和回风区域的每一子区域(即子送风单元和子回风单元)内设置温度传感器和湿度传感器,热交换区域的设备如服务器一般都会设置有采集器,采集其运行温度、热负荷等数据。采集到的数据通过无线或者有线方式发送到处理模块中。The collection module 200 is configured to collect the temperature of the sub-air supply unit and the sub-return unit and the device thermal load of the heat exchange area in real time, and send the collected data to the processing module 300 described below. Specifically, a temperature sensor and a humidity sensor may be disposed in each of the air supply area and the return air area (ie, the sub air supply unit and the sub return air unit), and the equipment of the hot swap area, such as a server, is generally provided with a collector. Collect data such as operating temperature and heat load. The collected data is sent to the processing module wirelessly or by wire.
所述处理模块300用于根据采集数据与预先设定的数据,实时调节每一子送风单元的水平方向的送风量和送风区域的垂直方向的送风量。进一步地,还用于根据采集数据与预先设定的数据实时调节每一子回风单元的回风量。具体来说,在水平截面方向实现高效冷却的平行气流组织,在垂直截面方向实现分层变风量差异化供冷(即二维动态送风)。同时,自动实现机柜二维空间的负荷与供冷的动态匹配。还可根据各机柜的不同温度要求,选择不同机柜的多温区差异化供冷,大幅提高冷能的利用效率。The processing module 300 is configured to adjust the air supply amount in the horizontal direction of each sub air supply unit and the air supply amount in the vertical direction of the air supply unit in real time according to the collected data and the preset data. Further, it is further configured to adjust the amount of return air of each sub-return unit in real time according to the collected data and the preset data. Specifically, the parallel airflow structure that achieves high-efficiency cooling in the horizontal cross-section direction realizes differential cooling of the stratified variable air volume in the vertical cross-sectional direction (ie, two-dimensional dynamic air supply). At the same time, the dynamic load matching of the two-dimensional space of the cabinet and the cooling is automatically realized. According to the different temperature requirements of each cabinet, different multi-temperature zones of different cabinets can be selected for different cooling, which greatly improves the utilization efficiency of cold energy.
进一步地,每一子送风单元的冷风通过对应设备后变成热风,再经过与其对应的子回风单元回到空调处理机组。还可以通过在每一子回风单元的回风管道上设置自动调节阀调节回风量。Further, the cold air of each sub-air supply unit passes through the corresponding device and becomes hot air, and then returns to the air-conditioning processing unit through the sub-return unit corresponding thereto. It is also possible to adjust the amount of return air by providing an automatic regulating valve on the return air duct of each sub-return unit.
在本方案中,可以设置一智能控制模型,根据采集数据和预先设定的数据,动态实时调节水平方向、垂直方向的送风量以及回风量,从而满足每一子送风单元对应的设备工作需求,使其工作温度和/或湿度在预定范围之内。以下是智能控制模型的具体说明:In this solution, an intelligent control model can be set, and the air supply amount and the return air amount in the horizontal direction and the vertical direction can be dynamically adjusted in real time according to the collected data and the preset data, thereby satisfying the equipment work corresponding to each sub air supply unit. The demand is such that its operating temperature and/or humidity is within a predetermined range. The following is a detailed description of the intelligent control model:

Please continue to refer to FIG. 4 , which is a schematic diagram of an embodiment of a two-dimensional dynamic air supply and energy saving system of the data center of the present invention. As shown in the figure, the two-dimensional dynamic air supply and energy-saving system comprises a horizontal air supply and a vertical air supply, and the vertical air supply enters the corresponding air supply area by the airflow of the common air passage through the air guiding hole 10 disposed on the side of the air supply area. . In the present embodiment, the horizontal air supply unit 20 is configured to perform air supply by the horizontal air supply unit 20 of each sub-area air supply unit. In this embodiment, the cabinet is divided into two sub-area air supply units, and each sub-area air supply unit is provided. There is a corresponding horizontal air supply device 20. It can adjust the air supply amount in the vertical direction by adjusting the size of the variable air volume module at the bottom or the size of the air guiding hole on the side. On the other hand, in the horizontal direction, the horizontal air blowing device 20 connected to the wind pool changes the amount of air blown in the horizontal direction.

After research and a large number of experiments, it is found that different heat loads have a certain relationship with the amount of air supplied. The following is a specific example to illustrate: when the inlet air temperature is 23 ° C, the average air outlet temperature of the cabinet is not more than 38 ° C, the minimum air supply volume required by the two-dimensional dynamic air supply system of the data center, the result is shown in Figure 6. Shown. Among them, the points in the figure are the results of simulation calculation, the curve is the result of nonlinear fitting, and the air volume and load of the two-dimensional dynamic air supply system in the data center (also The relationship between the heat load and the same) is as follows:
V=-2.80Q2+209.17Q-79.4V=-2.80Q 2 +209.17Q-79.4
其中,V为系统送风量,单位为m3/h;Q为机柜负荷,单位为kW。Where V is the air supply volume of the system, the unit is m 3 /h; Q is the load of the cabinet, and the unit is kW.
垂直方向上的送风是由共通风道的气流通过送风区域的侧面设置的导流孔进入所述送风区域,其可以通过调节底部的变风量模块或侧面的导流孔的大小来实现其垂直方向上的送风量的调节。而在水平方向上,与风库相连的水平送风装置,每一水平送风装置均对应一子送风单元。即划分好子送风单元后,每一子送风单元均对应设置一变风量模块(如变频风机),通过调节每一变频风机的频率来改变在水平方向上的送风量。The air supply in the vertical direction is obtained by the airflow of the common air passage passing through the air guiding hole provided on the side of the air supply area, and can be realized by adjusting the size of the variable air volume module on the bottom or the air guiding hole on the side. The adjustment of the amount of blown air in the vertical direction. In the horizontal direction, the horizontal air supply device connected to the wind pool, each horizontal air supply device corresponds to a sub air supply unit. After the sub-steam unit is divided, each sub-air supply unit is correspondingly provided with a variable air volume module (such as an inverter fan), and the air supply amount in the horizontal direction is changed by adjusting the frequency of each inverter fan.
数据中心的二维动态送风节能系统和数据中心内空调系统联合运行,通过送风压力(例如,所述送风压力采用地板下静压)将冷空气送入机柜内,数据中心的二维动态送风节能系统送风量与送风压力密切相关,如图7所示。静压与风量的关系为平行于横坐标的直线,直线与数据中心的二维动态送风节能系统送风量的交点为系统启动的临界点,当静压对应的风量大于数据中心的二维动态送风节能系统送风量时,无需开启数据中心的二维动态送风节能系统,制冷系统的送风压力可将冷空气有效送入机柜内;即:图7中交点右侧为数据中心的二维动态送风节能系统运行,交点左侧为制冷系统自运行。The two-dimensional dynamic air supply and energy-saving system of the data center is operated in conjunction with the air-conditioning system in the data center, and the cold air is sent into the cabinet through the air supply pressure (for example, the air supply pressure is under the floor static pressure), and the data center is two-dimensionally The air supply volume of the dynamic air supply system is closely related to the supply air pressure, as shown in Figure 7. The relationship between static pressure and air volume is a line parallel to the abscissa, and the intersection of the straight line and the air flow of the two-dimensional dynamic air supply system of the data center is the critical point of system startup. When the static pressure corresponds to the two-dimensional volume of the data center When the air supply capacity of the dynamic air supply system is increased, there is no need to open the two-dimensional dynamic air supply and energy-saving system of the data center. The air supply pressure of the refrigeration system can effectively send the cold air into the cabinet; that is, the right side of the intersection in Figure 7 is the data center. The two-dimensional dynamic air supply system is operated, and the left side of the intersection is the self-running of the refrigeration system.
则得到,数据中心的二维动态送风节能系统启动的临界点和机柜内热负荷的关系如图8所示。Then, the relationship between the critical point of the start of the two-dimensional dynamic air supply and energy saving system in the data center and the heat load in the cabinet is as shown in FIG. 8 .
即ΔP=14.37+0.81Q;That is, ΔP=14.37+0.81Q;
其中,ΔP为数据中心送风压力(即静压),单位为Pa;Q为机柜负荷,单位为kW。Where ΔP is the data center supply air pressure (ie static pressure), the unit is Pa; Q is the cabinet load, the unit is kW.
综上所述,根据不同负荷下,机柜内的气流场和温度场的分布,以及数据中心的二维动态送风节能系统送风量和热负荷的变化关系,模拟计算系 统能耗和机柜负荷变化的关系,结果如图9所示。其中,图中的点为模拟计算结果,曲线为非线性拟合结果,数据中心的二维动态送风节能系统功耗与负荷的关系如下式:
Figure PCTCN2016077732-appb-000001
In summary, according to the load distribution of the airflow field and temperature field in the cabinet under different loads, and the relationship between the air supply volume and the heat load of the two-dimensional dynamic air supply system in the data center, the energy consumption of the system and the load of the cabinet are simulated. The relationship of change, the result is shown in Figure 9. Among them, the points in the figure are the results of simulation calculation, the curve is the result of nonlinear fitting, and the relationship between power consumption and load of the two-dimensional dynamic air supply system in the data center is as follows:
Figure PCTCN2016077732-appb-000001
其中,W为系统能耗,单位为W;Q为机柜负荷,单位为kW。由此可知,数据中心的二维动态送风节能系统的能耗随负荷的增大而变化,如图9所示,该系统在不同热负荷下的最大能耗为150W,此时可输出的冷量为24kW,对比于传统制冷系统的能耗,该能耗可忽略不计。该系统和传统制冷系统联合运行时,提高了制冷系统的回风温度,提高了制冷系统中蒸发器侧的传热效率,增大了制冷系统的蒸发制冷量,提高了制冷系统的能效比。Where W is the system energy consumption, the unit is W; Q is the cabinet load, and the unit is kW. It can be seen that the energy consumption of the two-dimensional dynamic air supply system in the data center changes with the increase of the load. As shown in Fig. 9, the maximum energy consumption of the system under different thermal loads is 150W, which can be output at this time. The cooling capacity is 24 kW, which is negligible compared to the energy consumption of conventional refrigeration systems. When the system is operated in conjunction with the conventional refrigeration system, the return air temperature of the refrigeration system is increased, the heat transfer efficiency of the evaporator side in the refrigeration system is improved, the evaporative cooling capacity of the refrigeration system is increased, and the energy efficiency ratio of the refrigeration system is improved.

Return air temperature, improve the heat exchange efficiency of the refrigeration system, Thereby improving the energy efficiency ratio of the refrigeration system. The working principle of the two-dimensional dynamic air supply energy-saving system is as follows: the refrigeration system sends cold air into the floor overhead layer (in the static pressure box) in the data center, and the air supply pressure sends the cold air into the cabinet, and the two-dimensional dynamic transmission The wind energy-saving system automatically adjusts the air supply volume and the air supply pressure according to the temperature and heat load data. The hot air after the heat exchange is returned to the evaporator side of the refrigeration system after being processed by the return air system, so that the cycle is reciprocated to achieve temperature reduction in the data center. Energy saving. Through experiments, the two-dimensional dynamic air supply energy-saving system can improve the return air temperature of the refrigeration system and increase the utilization rate of the cooling capacity, thereby greatly reducing the energy consumption of the refrigeration equipment in the communication room and satisfying the safe operation of the electronic server in the communication room; The dynamic air supply system can improve the return air temperature of the refrigeration system by about 10 °C, and the energy efficiency ratio of the refrigeration system is increased by about 25.6%. The energy efficiency ratio of the system operation is calculated as follows:

Figure PCTCN2016077732-appb-000002
其中,:Qr为空调系统制冷量,单位为kW;W为空调系统运行能耗,单位为kW。Among them, Q r is the cooling capacity of the air conditioning system, the unit is kW; W is the operating energy consumption of the air conditioning system, the unit is kW.
提高系统运行的回风温度可提高蒸发器侧制冷剂和空气的传热温差,提高蒸发器处的换热量,即式中的空调系统制冷量,故可提高系统的能效比。其中,该式中只考虑了蒸发器侧的换热量,计算结果比实际运行节能效果偏低。实际运行时,提高室内侧的温度还可减少建筑围护结构的得热量,降低数据中心的冷负荷,减少空调的运行能耗。据统计,室内侧温度每提高1℃,可减少制冷系统的能耗5%-8%。二维动态送风节能系统可提高制冷系统的回风温度约10℃,即该系统可降低空调系统50-80%的能耗,节能潜力巨大!Increasing the return air temperature of the system operation can increase the heat transfer temperature difference between the refrigerant and the air on the evaporator side, and increase the heat exchange amount at the evaporator, that is, the cooling capacity of the air conditioning system in the equation, thereby improving the energy efficiency ratio of the system. Among them, only the heat exchange amount on the evaporator side is considered in the formula, and the calculation result is lower than the actual operation energy saving effect. In actual operation, increasing the temperature on the indoor side can also reduce the heat gain of the building envelope structure, reduce the cooling load of the data center, and reduce the operating energy consumption of the air conditioner. According to statistics, for every 1 °C increase in indoor temperature, the energy consumption of the refrigeration system can be reduced by 5%-8%. The two-dimensional dynamic air supply energy-saving system can increase the return air temperature of the refrigeration system by about 10 °C, that is, the system can reduce the energy consumption of the air-conditioning system by 50-80%, and the energy-saving potential is huge!
