Question: My data center is a limited floor space (1600 sq) and running at 18 kW per cabinet. The cooling experts are indicating that a load of 18 kW would require about 2700 CFM to cool the equipment. They also indicate that max let through on a "Tate" floor tile is 1300 CFM. In this scenario we designed a wider cold aisle to accommodate a (2:1 - 2.5:1) floor tiles to enclosure ratio to meet the CFM required by the equipment.
This scenario leads to the potential of high density exceeding traditional cooling capabilities whether using CPI's Vertical Exhaust Duct or not, if there is not the floor space for additional perf tiles then your equipment cold air demand can potentially exceed the let through ratio. If true, would there be a watt per square foot - line/threshold, based on traditional cooling, raised floor height etc ...
