Traditional Floor Grates vs. Triad Floor Grilles
With the floor grates providing the cold air to cool servers and other IT equipment, doing this effectively is a major way to improve energy efficiency. It is estimated that 50% of the Data Centre utility bill goes towards cooling, so making changes airflow management that results in raising CRAC unit set points can lead to cost savings being made.
For years the traditional Data Centre cooling systems have presented air to the cold aisle via floor grilles, floor grates or perforated tiles. However, these types of tiles caused short cycling where air flowed past the bottom of the tile. This lead to Data Centre managers adding more CRAC units, and lowering set points in order to cool the room. The cost of this inefficiency is the additional expenditure for CRAC units, and higher electricity bills. In a study on ‘Airflow in the Data Centre’, Dr Bob F. Sullivan and Kenneth G. Brill estimate that only 28% of the air in the raised floor system actually gets to the servers. This means 72% of the air is wasted and is only present to guide the other 28%. Data Centres are basically using air to divert air.
Triad floor grilles are different from traditional flat bottom floor grilles and floor grates; Triad floor grilles feature a unique Hi-Plume Stratification Fin which is scientifically designed to redirect and concentrate the available air to the servers, improving the efficiency of the cooling system.
