Mechanical structures for electrical and electronic equipment - Aisle containment for IT cabinets - Part 2: Details of air flow, air separation and air cooling requirements

IEC 62966-2:2020 is dedicated to aisle containment techniques for information technology (IT) equipment typically used in data centres, describes the quantification of its air tightness, in particular the air loss ratio that describes the content of the volumetric flow not used for cooling the IT equipment. This ratio provides an index of efficiency, being inversely proportional to efficiency (the lower this ratio, the higher the efficiency). This document provides methods to measure an aisle containment air leakage rate and defines a classification system for aisle containment leakage. This document defines: - the measurement of the air leakage of the individual components of an aisle containment; - a method for calculating the air leakage of an aisle containment based on its individual components; - a method for calculating the air leakage rate of an aisle containment in relation to the utilised IT equipment; - a classification system for aisle containment leakage.

Structures mécaniques pour équipements électriques et électroniques - Confinement d’allées pour les baies informatiques - Partie 2: Détails des exigences relatives au flux d’air, à la séparation des flux d’air et au refroidissement par air

IEC 62966-2:2020 est dédiée aux techniques de confinement pour les équipements informatiques typiquement utilisés dans les centres de données, décrit la quantification de leur étanchéité, et plus particulièrement le taux de fuite d’air, qui définit le débit volumique qui ne sert pas à refroidir les équipements informatiques. Ce taux constitue un indice de rendement, fonctionnant à proportionnalité inverse (plus le taux diminue, plus le rendement augmente). Le présent document donne des méthodes pour mesurer le taux de fuite d’air d’un confinement, et définit un système de classification des fuites du confinement. Le présent document définit: - la mesure des fuites d’air des composants individuels d’un confinement; - une méthode de calcul des fuites d’air d’un confinement, basée sur ses composants individuels; - une méthode de calcul du taux de fuite d’air d’un confinement, en fonction des équipements informatiques utilisés; - un système de classification des fuites du confinement.
