Investigation On Airflow Simulation Platform And Air Distribution Of Datacom Room

Datacom room is a centralized data and information storage、management and transmission room, many computer servers、data storage systems and communication equipment are operating in it. Recently, with the development of miniaturization、 functional diversities and operating speed of these electronic equipment, the heat dissipating capacity per area increases rapidly, which leads to the higher requirement on the environment conditions of datacom room; On the other hand, as the main heat management equipment in datacom room, air conditioning system consumes plenty of power. Reasonable air distribution design and cooling the equipment efficiently are of great importance for energy saving and safe and stable operating of datacom room.Combining with the installation features of the servers, this paper takes a typical datacom room with cold aisle and hot aisle isolation layout, underfloor air supply system for example, points out that the unreasonable hot air and cold air mix caused by the local space between two adjacent servers. In order to improve the local air distribution, inducers are proposed to install on both front and rear of the server.Taken both Computational Fluid Dynamics technology as the study tool and parametric technology as guidance core, a numerical simulation platform is built based on Visual Studio programming platform and openGL graphical user interface development technology. On the basis of it, supply heat index (SHI) and return heat index (RHI) are used to systematic evaluate and compare the influence of different shapes or angles on the air distribution in the datacom room. Results shows that through installing inducers on both front and rear of the server, the air distribution in the datacom can be improved when the angle of flat inducer is bigger than28°, or the angle of arc inducer is bigger than16°. The bigger the angle of the inducer is, the more efficiency the air distribution can be improved in the datacom. Besides, under the condition of the same angle with flat inducer and arc inducer, arc inducer has better air distribution improvement effect than that of flat inducer.
