Abstract

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.
