NUMERICAL INVESTIGATION ON AIR FLOW CHARACTERISTICS INSIDE A TELECOMMUNICATION SHELTER ROOM

Abstract

The main point of this thesis is to investigate the thermal performance and air flow characteristics inside a telecommunication shelter by changing the place of computer room air conditioning (CRAC) to get optimum air distribution. The study is carried out using computational fluid dynamics (CFD) simulation using a commercial CFD code ANSYS 17.

The investigation conducted for four cases, first and second cases represent the change of CRAC place and their effect on air flow distribution, third and fourth case represent the separation between inlet and outlet flows of battery cabinet and their effect on thermal performance.

It’s observed from the results that the temperature of supplied cooled air to main components decreases by percentages of 23.5%, 7.6%, 23.6% and 35.3% for different devices due to air flow distribution enhancement. Finally, it’s observed that the best performance for air distribution inside the shelter is obtained from fourth case.
