As part of baselining energy consumption and cooling performance Shiang Chin, 4th year student at Imperial College London, helped with measuring computer rooms airflow.
He measured airflow and temperature above each perforated tile and re-adjusted dumpers to maximize the overall airflow. There is a variance across the tiles due to undefloor obstacles which are not easily movable. Once the project “cold aisle” and “free cooling” tasks are complete we can re-assess and review how airflow changed and whether it needs re-adjustment.
On the graph X axis is a tile number (from 503, entrance, towards 535, the rear of the room). Thanks Shiang!
