Abstract

U sklopu diplomskog rada je provedena stacionarna i tranzijentna numerička simulacija strujanja zraka u modularnom podatkovnom centru za tri konfiguracije okruženja računalne opreme: toplo okruženje, hladno okruženje i opcija bez okruženja.
Kako bi to bilo moguće, prvo su proračunate i odabrane rashladne jedinice. Pri tome je uzeto u obzir da jedinice trebaju zadovoljiti redundanciju rashladnog sustava, odnosno da sustav treba funkcionirati i u slučaju da jedna jedinica ne radi. Stacionarna analiza je provedena za sustav u stanju normalnog rada i za redundantni sustav, dok je tranzijentna analiza provedena za slučaj nestanka glavnog napajanja podatkovnog centra i prebacivanja napajanja na sekundarni izvor.
Analiza je provedena u programskom paketu 6Sigma DCX Room 15, a svrha analize je procijeniti sve tri konfiguracije u pogledu vrijednosti temperature zraka na ulazu u računalnu opremu i uz dodatnu ekonomsku analizu odabrati jednu konfiguraciju kao konačno rješenje. Za tu konfiguraciju je izrađen tlocrt podatkovnog centra s pripadajućom strojarskom opremom.

Abstract (english)

In this thesis was performed stationary and transient CFD analysis of air flow in a modular data center. It was performed for three different IT equipment containments: hot containment, cold containment, and an option without containment.
To make this possible, the first step was calculation and selection of the cooling units. It is considered that the units should meet the redundancy of the cooling system, i.e. that the system should function even if one of the units is not in working condition. A stationary analysis was performed for the system in normal operating conditions and for the redundancy scenario, while a transient analysis was performed for analyzing power outage scenario.
The analysis was performed in the software package 6Sigma DCX Room 15 with major purpose being the evaluation of all three configurations with respect to the air temperature at the inlet of the IT equipment. Additional economic analysis was done to select one configuration as the final solution. A floor plan of the data center with associated mechanical equipment was made for selected solution.
