En af de mest effektive metoder til at \u00f8ge energieffektiviteten i moderne datacentre og reducere driftsomkostningerne er isoleringssystemer. De kaldes ogs\u00e5 systemer til containerisering af varme og kolde korridorer. Hoved\u00e5rsagen er, at det prim\u00e6re forbrug af overskydende kapacitet i datacentret kommer fra k\u00f8lesystemet. Jo mindre belastning der er p\u00e5 det (reduktion af elregninger, j\u00e6vn fordeling af belastning, reduktion af slid p\u00e5 ingeni\u00f8rsystemer), des h\u00f8jere er energieffektiviteten (forholdet mellem den samlede brugte effekt og den nyttige effekt (forbrugt til IT-belastning)). <\/p>\n

Denne tilgang er blevet meget udbredt. Det er en anerkendt standard for driften b\u00e5de globalt og i Rusland. datacentre<\/a>Hvad skal man vide om isoleringssystemer for at kunne bruge dem mest effektivt? <\/p>\n

For det f\u00f8rste \u2013 hvordan et k\u00f8lesystem generelt er konstrueret og fungerer. I datacentret er der monteringsskabe (rack), hvor IT-udstyret er installeret. Dette udstyr har brug for konstant k\u00f8ling. For at undg\u00e5 overophedning er det n\u00f8dvendigt at tilf\u00f8re en kold luftstr\u00f8m til den forreste d\u00f8r af skabet og fjerne den varme luft, der kommer fra den bageste del. Men hvis der ikke er nogen barriere mellem de to zoner \u2013 den kolde og den varme \u2013 kan begge luftstr\u00f8mme blandes, hvilket reducerer k\u00f8lingen og \u00f8ger belastningen p\u00e5 airconditionen.
\nFor at forhindre blanding af varm og kold luft er det n\u00f8dvendigt at opbygge et luftcontaineriseringssystem.<\/p>\n

\"Isoleringssystemer
\n<\/a><\/noindex>
\nHandlingsprincippet:<\/u> Den lukkede volumen (container) akkumulerer den kolde luft, s\u00e5 den ikke blandes med den varme og giver de h\u00f8jt belastede skabe mulighed for at f\u00e5 tilstr\u00e6kkelig kulde.<\/p>\n

Placering:<\/u> Luftcontaineren skal placeres mellem to r\u00e6kker af monteringsskabe eller mellem en r\u00e6kke skabe og v\u00e6ggen i lokalet. <\/p>\n

Konstruktion:<\/u> Alle sider af containeren, der adskiller de varme og kolde zoner, skal v\u00e6re opdelt med skillev\u00e6gge, s\u00e5 den kolde luft kun passerer gennem IT-udstyret. <\/p>\n

Yderligere krav:<\/u> Containeren m\u00e5 ikke hindre installation og drift af IT-udstyr, installation af kommunikation, drift af overv\u00e5gningssystemer, belysning, brandslukning samt skal kunne integrere med adgangskontrolsystemet i maskinrummet.
\nOmkostninger: Dette er et ret positivt aspekt. For det f\u00f8rste er containeriseringssystemet langt fra den dyreste del af hele k\u00f8lesystemet. For det andet kr\u00e6ver det ikke yderligere vedligeholdelsesomkostninger. For det tredje har det en positiv indvirkning p\u00e5 besparelser, da opdelingen af luftstr\u00f8mme og fjernelse af lokale overophedningspunkter reducerer og j\u00e6vnt fordeler belastningen mellem klimaanl\u00e6ggene. Den samlede \u00f8konomiske effekt afh\u00e6nger af st\u00f8rrelsen p\u00e5 maskinrummet og k\u00f8learkitekturen. <\/p>\n

Anbefaling:<\/u> N\u00e5r IT-udstyr udskiftes med mere kraftfulde modeller, er det ikke altid n\u00f8dvendigt at opgradere klimaanl\u00e6ggene til mere kraftige modeller. Nogle gange er det tilstr\u00e6kkeligt at installere et isolationssystem, hvilket kan give 5-10% reserve i kuldeproduktion.
