摘  要:IDC(Internet Data Center)即互联网数据中心。它是伴随着互联网不断发展的需求而迅速发展起来的,已成为了互联网产业中不可或缺的重要一环。它为互联网内容提供商(ICP)、企业、媒体和各类网站提供大规模、高质量、安全可靠的专业化服务器托管、空间租用、网络批发带宽以及ASP、EC等业务。

   随着通信设备集成度的日益提高,机房内设备的功率密度越来越高,耗电量平均3~4kW/机架的情况变得越来越常见,设备的发热量也越来越大。机房专用空调机组采用传统的“先冷环境再冷设备”的工作方式,不仅不能适应大功率机房的需求,难以避免机房过热区的存在,而且浪费了大量的电能

   为了有效解决上述难题,空调界在分析与评估的基础上,提出了定点精确送风的概念。

   本文从定点精确送风的理念、实施及评估等多个方面对其进行了全面论述与探讨。

   IDC机房在进行精确定点精确送风改造之后,其改造效益将会是多方面的。首先,通过精确送风改造可直接解决机房的局部过热问题,保证了机房设备运行的安全性。其次,通过精确送风改造,由于机房热环境得到改善,因此机房可增加部分设备容量,从而提高了机房的利用率。再次,也是最直观的效益表现,就是机房的节能效益。如果实施了精确送风,可显著降低机房空调能耗。

ABSTRACT:IDC means internet data center, it developed rapidly with the growing demand of internet. And it has become one of the most essential parts of the internet industry. It provides large-scale、high quality、safe and reliable services of professional server hosting、space rental、wholesale broadband network、ASP and EC for ICP、Enterprises、mass media and various web sites.

  As the integration level of the communication equipment is increasing day by day, the power density of the equipment room in the machine room is increasing too. It is common to see that every unit consumes 3~4kw. The heat given off by the equipment is growing too. The professional air conditioning units take the traditional approach of cold the equipment after the environment, which can’t meet the requirement of power room and can't avoid the emergence of the overheated zone ,meanwhile, it waste a lot of power.

  The experts in air-conditioning industry had put forward the concept of fixed-point precise ventilating on the basis of analysis and evaluation to settle the problems efficiently. 

  This paper has made a comprehensive exposition and discussion from the perspective of the conception of fixed-point precise ventilating, implement and evaluation.

  Once the IDC has finished the process of fixed-point precise ventilating and rebuilt the precise ventilating, the transformation efficiency will be considerable in many respects. Firstly, we could solve the problem of local overheating directly through the rebuilt of precise ventilating. Secondly, the thermal environment will be improved after the rebuilt of precise ventilating and then we could enlarge the equipment capacity and improve its utilization. Lastly, also the most intuitive performance is its energy efficiency. If we take the method of precise ventilating, the energy consumption will be reduced remarkably.
