Description
Technical field
The utility model relates to a kind of Air flow system, especially for the refrigeration unit of data center.
Background technology
Along with the development of internet, data center's construction speed is surprising, research shows that Chinese data center total quantity in 2012 has reached 510,530, IDC predicts that this market will keep close to double-digit growth rate at the coming five years, and the large-scale data center proportion that scale is more than or equal to 3000 standard frames increases year by year. In order to guarantee the stable operation of data center apparatus, need to keep the inner 365 days constant temperature constant humidity of data center, namely data center needs cooling throughout the year, met the design specification of equipment by ambient parameters such as the temperature of Air-condition system control data center, humidity, air cleaning degree, consequent huge power consumption becomes data center already and develops unavoidable problem. In fact in data center, the electric energy of all devices consumption such as the server of real carrying business, network, the storage electric energy consumed with refrigerated air-conditioning system that adds up is similar, how by electric energy more for business devices such as servers, instead of be wasted on the non-necessary equipment such as refrigeration system, it is data center's urgent need to solve the problem.
In the epoch of promotion " low carbon emission reduction, green environmental protection ", part experts and scholars just propose the concept of nature cooling (FreeColling). Naturally cooling refers to a process, in i.e. winter and transition season, if when outdoor temperature is lower than data center's return air temperature, outdoor natural cooling source (air or water) can be utilized, when not opening or part opens compressor, by data center's decrease in temperature to assigned temperature. " State Council is about accelerating to cultivate and the decision of development strategy new industry " points out, area cold at weather, energy abundance should preferentially be built in super large-scale data center, object be also make full use of winter and excessive season north cold air to cool machine room. Naturally cooling can effectively reduce the energy resource consumption of data center's refrigeration system, but area, north serious water shortage usually, and therefore, natural air cooled technology becomes popular technology in recent years.
The solution that current data center utilizes nature cold wind to carry out freezing mainly contains directly cooling naturally and indirectly naturally cools two kinds of modes. Wherein, direct new wind nature cooling system need to add strict filtration device and humidification apparatus could meet data center environment to the requirement of humidity, cleaning degree and pollutant levels, strongly limit its application in refrigeration systems. In data center's refrigeration system of applying natural cooling technology, more employing efficient heat transfer, energy-saving material-saving the indirect natural cooling system of the features such as tool environment-friendly function. Data center's lateral line only at outdoor increase heat exchanger, need to be connected into independent closed loop, has work fluid in loop by this system, by the effect fluid of media pump at loop Inner eycle, is introduced by natural cooling source and indoor continues cooling to data center. But the north minimum temperature at area night in winter is-20～-30 DEG C, when there is extreme weather, even temperature is lower, once the work fluid in pipeline is changed into ice, pipeline just has the danger being inflated rhegma, and therefore outdoor pipeline must consider antifreeze measure. Owing to data center's lateral line is a closed loop, owner has to the anti-icing fluid adding high concentration in whole closed loop for this reason. The data center of, pipeline length big for scale, this will cause the significantly increase of owner investment volume.
