数据中心服务器芯片最佳理想工作温度是25℃,但是绝大多数数据中心为了节省冷却费用都把服务器工作环境温度设定到40～60度,导致数据中心服务片芯片温度工作到100～125℃,有很多可以查询到的资料证明,如果将数据中心服务器芯片工作在最佳25度的温度下,其运算能力和设备寿命都会成倍增长,为此微软公司将数据中心放到4℃的海水中进行冷却；本发明的零碳数据中心具有天然的制冷功能,可以使数据中心的环境工作温度在0度以下,从而保证数据中心服务器芯片工作在最佳25度的温度下,但数据中心不是一个孤立的***,因为数据中心内部的工作温度和外部的环境温度之间有温差,建筑物的表面要和环境进行温度交换,数据中心内部和外部环境要进行新风交换,也会将外部环境热量带到数据中心内部,至于外部环境热量进入到数据中心内部的数值,与建筑物的表面面积,新风的交换量,建筑物外墙的保温系数,外部风力大小,是否有阳光照射,是由很多变量决定的如附件；某数据中心有机架3万台，建筑面积25万平米,外部卫护面积不下于30万平方米,如果数据中心内部设定工作温度为0度,外部环境温度假设为25℃,每个机架安放服务器20个，每台服务器功率550瓦，每个机架耗电量11千瓦，所有服务器总耗电量为33万千瓦，UPS耗电量取服务 器总耗电量的10％，数据中心总耗电量为36.3万千瓦，冷力发电机容量取40万千瓦，由于数据中心始终工作在低温状态，外部环境热量不可避免的会传送到数据中心内部，零碳冷力发电机将渗透进来的外部环境热能和服务器的热能同时都转化为电能,根据能量守恒定律,能量必须平衡,所以大概率的事件数据中心是运行在负能耗状态，至于具体能够对外输出多少能量,是由数据中心的内部工作温度与外部环境温度之间的很多因素决定的,如果要求数据中心内部的工作温度高于环境工作温度,则是需要外部提供补充能量的,所以零碳数据中心在正常的很多情况下不但不消耗能量，还可以向外部输送电能,因此也可能需要提供能量的外输通道。The ideal working temperature of the data center server chip is 25°C, but most data centers set the server working environment temperature to 40-60°C in order to save cooling costs, resulting in the temperature of the data center service chip chip working at 100-125°C , there are a lot of information that can be found to prove that if the data center server chip works at the optimal temperature of 25 degrees, its computing power and equipment life will increase exponentially. The zero-carbon data center of the present invention has a natural cooling function, which can make the ambient operating temperature of the data center below 0 degrees, thereby ensuring that the server chips in the data center work at the optimum temperature of 25 degrees, but the data center is not An isolated system, because there is a temperature difference between the working temperature inside the data center and the external ambient temperature, the surface of the building needs to exchange temperature with the environment, and the inside of the data center and the external environment need to exchange fresh air, which will also transfer heat from the external environment. Bringing it into the data center, as for the value of the external environment heat entering the data center, it is related to the surface area of the building, the amount of fresh air exchange, the thermal insulation coefficient of the outer wall of the building, the magnitude of the external wind force, and whether there is sunlight, it is determined by many factors. Variables are determined in the attachment; a data center has 30,000 racks, a building area of 250,000 square meters, and an external guard area of no less than 300,000 square meters. If the internal working temperature of the data center is set to 0 degrees, the external ambient temperature is assumed to be 25 ℃, 20 servers are placed in each rack, the power of each server is 550 watts, and the power consumption of each rack is 11 kilowatts. The total power consumption of all servers is 330,000 kilowatts. 10%, the total power consumption of the data center is 363,000 kilowatts, and the capacity of the cooling power generator is 400,000 kilowatts. Since the data center is always working at a low temperature, the heat from the external environment will inevitably be transmitted to the inside of the data center, zero-carbon cooling The generator converts the thermal energy of the infiltrated external environment and the thermal energy of the server into electrical energy at the same time. According to the law of energy conservation, the energy must be balanced, so there is a high probability that the event data center is running in a state of negative energy consumption. As for how much energy can be output externally , is determined by many factors between the internal operating temperature of the data center and the external ambient temperature. If the internal operating temperature of the data center is required to be higher than the ambient operating temperature, it needs to provide supplementary energy from the outside, so the zero-carbon data center is in In many normal cases, not only does it not consume energy, but it can also transmit electric energy to the outside, so it may also be necessary to provide an external transmission channel for energy.
数据中心的产品是信息，信息传递中消耗的能量可以忽略不计，零能耗数据中心将电能转变为热能，热能转变为电能，周而复始反复循环，能量守恒，从而为数据中心将来的大发展开辟了无限的可能。The product of the data center is information, and the energy consumed in the transmission of information is negligible. The zero-energy data center converts electrical energy into heat energy, and heat energy into electrical energy. The cycle is repeated and the energy is conserved, thus opening up a new era for the future development of the data center. The possibilities are endless.
