For a typical air-cooled datacenter project, the actual air distribution in a data hall has a great impact on the operation of the whole facility. According to an investigation by Uptime Institute (the global data center authority), more than half of airflow is wasted through bypass in many data center, resulting in a large amount of wasted cooling energy.
AIRSYS proposes the concept of Airflow Efficiency (AFE), which provides quantitative data for quantifying and comparing airflow conditions in different data centers.
The smaller the result for AFE, the higher the efficiency of airflow organization and therefore a smaller proportion of bypass airflow.
AFE is also an important index for COP analysis in a data center:
