具体实施方式detailed description
本发明提供一种数据中心空调供冷节能***及其实现方法，为使本发明的目的、技术方案及效果更加清楚、明确，以下对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。The present invention provides a data center air conditioning cooling energy saving system and an implementation method thereof. In order to make the objects, technical solutions and effects of the present invention more clear and clear, the present invention will be further described in detail below. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
请参阅图2，本发明提供的数据中心空调供冷节能***设置在回风管道上，所述回风管道用于将热风从机柜送回精密供冷空调，其中，所述数据中心空调供冷节能***包括：第一冷却水换热***100、第二冷却水换热***200和蓄水装置300；冷却水11从第一冷却水换热***100通过第一出水管道110流入第二冷却水换热***200，再通过第二出水管道111进入到蓄水装置300中，再然后由进水管道120流入第一冷却水换热***100。Referring to FIG. 2, the data center air conditioning cooling energy saving system provided by the present invention is disposed on a return air duct, and the return air duct is used for returning hot air from the cabinet to the precision cooling air conditioner, wherein the data center air conditioner is cooled. The energy saving system includes: a first cooling water heat exchange system 100, a second cooling water heat exchange system 200, and a water storage device 300; the cooling water 11 flows from the first cooling water heat exchange system 100 through the first water outlet pipe 110 into the second cooling water The heat exchange system 200 then enters the water storage device 300 through the second water outlet pipe 111, and then flows into the first cooling water heat exchange system 100 from the water inlet pipe 120.
具体来说，所述设置在机房空间内的第一冷却水换热***100用于和回风管道的热风进行热交换，所述回风管道的热风由机柜通过回风管道送回精密供冷空调；该热风温度较高(一般来说，可以达到38℃)，所述热风通过第一冷却水换热***100时，与第一冷却水换热***100内的冷却水进行热交换：冷却水吸收热量升温，热风温度降低，精密供冷空调的耗能量就越少(一般来说，冷凝温度每降低一度，设备的功耗率降低约3％到4％)。Specifically, the first cooling water heat exchange system 100 disposed in the room space is used for heat exchange with the hot air of the return air duct, and the hot air of the return air duct is sent back to the precision cooling by the cabinet through the return air duct. Air conditioning; the hot air temperature is higher (generally, 38 ° C can be reached), and the hot air passes through the first cooling water heat exchange system 100, and exchanges heat with the cooling water in the first cooling water heat exchange system 100: cooling The water absorbs heat and the hot air temperature decreases. The energy consumption of the precision cooling air conditioner is less (generally, the power consumption rate of the equipment is reduced by about 3% to 4% for every condensing temperature decrease).
升温的冷却水通过第一出水管道110进入到第二冷却水换热***200，进行再次的热交换：第二冷却水换热***200设置在室外环境中，流经第二冷却水换热***200内的冷却水与室外环境之间进行热交换(因为室外环境温度低于机房空间内的温度)，冷却水向室外环境中的空气放热，从而降低了冷却水的温度。The warmed cooling water enters the second cooling water heat exchange system 200 through the first water outlet pipe 110, and performs heat exchange again: the second cooling water heat exchange system 200 is disposed in the outdoor environment and flows through the second cooling water heat exchange system. The cooling water in 200 exchanges heat with the outdoor environment (because the outdoor ambient temperature is lower than the temperature in the room space), and the cooling water releases heat to the air in the outdoor environment, thereby lowering the temperature of the cooling water.
降低了温度的冷却水再通过第二出水管道111进入到蓄水装置300中，在本实施例中，所述蓄水装置为一蓄水箱，其内部设置有一浮球，用于检测蓄水装置内的水位，蓄水装置内还包括一补水结构，用于当蓄水装置内 的水位下降到水位阀值后，对蓄水装置内进行补水。蓄水装置300中的冷却水再从进水管道120流入第一冷却水换热***100，实现了冷却水的循环。The cooling water whose temperature has been lowered enters the water storage device 300 through the second water outlet pipe 111. In the embodiment, the water storage device is a water storage tank, and a floating ball is disposed inside the water storage device for detecting water storage. The water level in the device, the water storage device further includes a water replenishing structure for use in the water storage device After the water level drops to the water level threshold, the water storage device is replenished. The cooling water in the water storage device 300 flows from the water inlet pipe 120 into the first cooling water heat exchange system 100, thereby achieving circulation of the cooling water.
而本方案中的优点之一在于，采用虹吸原理在不额外消耗能量的情况下，保证了水循环。虹吸现象是液态分子间引力与位能差所造成的，即利用水柱压力差，使水上升后再流到低处。由于管口水面承受不同的大气压力，水会由压力大的一边流向压力小的一边，直到两边的大气压力相等，容器内的水面变成相同的高度，水就会停止流动。利用虹吸现象很快就可将容器内的水抽出。One of the advantages of this solution is that the siphon principle ensures water circulation without additional energy consumption. The siphon phenomenon is caused by the difference between the liquid molecules' gravitational force and the potential energy, that is, the water column pressure difference is used to make the water rise and then flow to a low position. Since the water surface of the nozzle is subjected to different atmospheric pressures, the water will flow from the pressure side to the pressure side until the atmospheric pressure on both sides is equal, and the water surface in the container becomes the same height, and the water stops flowing. The water in the container can be quickly withdrawn by siphoning.
假设冷却水在第一冷却水换热***吸热升温进行热交换时，吸收一定的热量Q；则根据下述之比热容(比热)公式：It is assumed that the cooling water absorbs a certain amount of heat Q when the first cooling water heat exchange system heats up and heats up; according to the specific heat capacity (specific heat) formula described below:
Q＝cmΔT；Q=cmΔT;
则可以结算出冷却水的升高温度ΔT，其中，Q为吸收(或放出)的热量；m是物体的质量，ΔT是吸热(放热)后温度所上升(下降)值，c表示比热容(水的比热容为4.2)。Then, the rising temperature ΔT of the cooling water can be settled, wherein Q is the absorbed (or released) heat; m is the mass of the object, ΔT is the rising (decreasing) value of the temperature after the endothermic (exothermic), and c is the specific heat capacity. (The specific heat capacity of water is 4.2).
另外，根据公式：Also, according to the formula:
W＝CρvA；W=CρvA;
其中，W是加热功率，C是水的比热，ρ是水的密度，v是水上升的速度，A是容器的截面。可以计算出水上升的速度v。Where W is the heating power, C is the specific heat of water, ρ is the density of water, v is the rate at which water rises, and A is the cross section of the vessel. The speed v of the water rise can be calculated.
进一步地，还可以包括一用于调节蓄水装置相对于第一冷却水换热***水位的第二调节装置，所述第二调节装置连接蓄水装置。其用来根据虹吸原理，调节蓄水装置相对于第一冷却水换热***水位，令两者之间有一高度差，从而辅助蓄水装置的水向第一冷却水换热***流动。Further, a second adjusting device for adjusting the water level of the water storage device relative to the first cooling water heat exchange system may be included, and the second adjusting device is connected to the water storage device. It is used to adjust the water level of the water storage device relative to the first cooling water heat exchange system according to the siphon principle, so that there is a height difference between the two, thereby assisting the water of the water storage device to flow to the first cooling water heat exchange system.
虹吸原理就是连通器的原理，来水端水位高，出水口用手掌或其他物体封闭住。此时管内压强处处相等。一切安置好后，打开出水口，虽然两边的大气压相等，但是来水端的水位高，压强大，推动来水不断流出出水口。其虹吸效果如图3所示，因为第一容器10的水位高于第二容器20，通 过虹吸原理，实现水从第一容器10中流入到第二容器20内。The siphon principle is the principle of the connected device. The water level at the water end is high, and the water outlet is closed by palms or other objects. At this point, the pressure inside the tube is equal. After everything is set up, open the water outlet. Although the atmospheric pressures on both sides are equal, the water level at the water inlet is high and the pressure is strong, pushing the water out of the water outlet. The siphon effect is as shown in FIG. 3, because the water level of the first container 10 is higher than that of the second container 20, Through the siphon principle, water is introduced from the first container 10 into the second container 20.
第一冷却水换热***的水温度高于蓄水装置的水温，进水管道120设置在第一冷却水换热***的底部，其输入的温度水温低于第一冷却水换热***的水温，第一冷却水换热***的冷却水吸热升温进行热交换时，里面的水受热膨胀，密度变小，就上升到第一冷却水换热***的顶部，完成了整个热交换过程，且无需额外提供动力，即保证了冷却水从第一冷却水换热***的底部升到第一冷却水换热***的顶部；另外，在蓄水装置内，密度较大的冷水则回流到蓄水装置的底部，从而实现了整个冷却水循环，该过程也可以视为热虹吸效应。The water temperature of the first cooling water heat exchange system is higher than the water temperature of the water storage device, and the water inlet pipe 120 is disposed at the bottom of the first cooling water heat exchange system, and the input temperature water temperature is lower than the water temperature of the first cooling water heat exchange system. When the cooling water of the first cooling water heat exchange system heats up and heats up, the water inside is heated and expanded, and the density becomes small, and rises to the top of the first cooling water heat exchange system, completing the entire heat exchange process, and No additional power is required to ensure that the cooling water rises from the bottom of the first cooling water heat exchange system to the top of the first cooling water heat exchange system; in addition, in the water storage device, the denser cold water flows back to the water storage. The bottom of the unit, thus achieving the entire cooling water cycle, which can also be considered a thermosiphon effect.
进一步地，所述第一冷却水换热***和第二冷却水换热***分别包括一换热盘管，使热风通过换热盘管后被冷却，以降低回到精密供冷空调的热风温度，来达到节能的目的。所述第一冷却水换热***的换热效率与换热盘管的面积有关，因此，可以根据需要吸收的热量来设置换热盘管的面积。Further, the first cooling water heat exchange system and the second cooling water heat exchange system respectively comprise a heat exchange coil, so that the hot air is cooled after passing through the heat exchange coil to reduce the hot air temperature returning to the precision cooling air conditioner. To achieve the purpose of energy saving. The heat exchange efficiency of the first cooling water heat exchange system is related to the area of the heat exchange coil. Therefore, the area of the heat exchange coil can be set according to the heat to be absorbed.
进一步地，所述的数据中心空调供冷节能***中，所述第二冷却水换热***还包括：一小型水泵，用于将第二冷却水换热***的水通过出水管道抽入到蓄水装置中。所述小型水泵的功率很低，其可以满足将第二冷却水换热***的水通过出水管道抽入到蓄水装置中即可。Further, in the data center air conditioning cooling energy saving system, the second cooling water heat exchange system further includes: a small water pump for pumping water of the second cooling water heat exchange system through the water outlet pipe In the water device. The small water pump has a low power, which can satisfy the drawing of the water of the second cooling water heat exchange system into the water storage device through the water outlet pipe.
需要注意地是，本发明能够实现冷却水循环的关键在于：室内温度高于室外环境温度，而当室外温度高于室内温度(如夏天较热)或者热交换功率过低时，则不采用本发明的数据中心空调供冷节能***。即包括一开关装置，用于当室外环境中的温度高于预定温度阀值时，关闭所述数据中心空调供冷节能***。It should be noted that the key to the cooling water circulation of the present invention is that the indoor temperature is higher than the outdoor ambient temperature, and when the outdoor temperature is higher than the indoor temperature (such as hotter in summer) or the heat exchange power is too low, the present invention is not used. Data center air conditioning cooling energy saving system. That is, a switching device is included for turning off the data center air conditioning cooling energy saving system when the temperature in the outdoor environment is higher than the predetermined temperature threshold.
另外，所述的数据中心空调供冷节能***中，还包括：用于检测第一冷却水换热***两端的水温的第一温度检测装置以及，用于检测第二冷却水换热***两端的水温的第二温度检测装置。通过第一、第二温度检测装 置，我们可以算出实际上热交换的效率以及节能的具体数值，从而来根据需要，调节相应的第一、第二冷却水换热***的盘管的大小和尺寸。In addition, the data center air conditioning cooling energy-saving system further includes: a first temperature detecting device for detecting water temperature at both ends of the first cooling water heat exchange system; and detecting the two ends of the second cooling water heat exchange system A second temperature detecting device for water temperature. Through the first and second temperature detection devices By setting, we can calculate the actual heat exchange efficiency and the specific value of energy saving, so as to adjust the size and size of the coils of the corresponding first and second cooling water heat exchange systems as needed.
更进一步地，所述第二冷却水换热***还可以包括一调节装置，用于根据室外环境的风速和/或风向，来调节第二冷却水换热***的位置，以实现第二冷却水换热***的热交换效率最大。Further, the second cooling water heat exchange system may further include an adjusting device for adjusting the position of the second cooling water heat exchange system according to the wind speed and/or the wind direction of the outdoor environment to implement the second cooling water. The heat exchange system has the highest heat exchange efficiency.
经过实验研究，当满足如下条件时，水泵开始工作：After experimental research, the pump starts to work when the following conditions are met:
T1-T2＜T0T1-T2<T0
其中，T1表示第一出水管道与第一冷却水换热***连通的位置的水温；Wherein, T1 represents a water temperature at a position where the first water outlet pipe communicates with the first cooling water heat exchange system;
T2表示第二出水管道与第二冷却水换热***连通的位置的水温；T2 represents the water temperature at a position where the second outlet pipe communicates with the second cooling water heat exchange system;
