Perforated Floor Tile Cfm

Matching equipment loads with the required cfm then matching the floor tiles with the required cfm will provide the correct amount of air flow for that rack.

Perforated floor tile cfm. By optimizing the flow characteristics it might be possible to realize flows as high as 500 cfm. Flow rates as high as 700 800 cfm per tile are possible with tiles with the highest percent open rating. The flow resistance of the perforated tiles was measured on a flow bench and is given by the following expression. Perforated tiles on a raised floor often deliver sub stantially more or less airflow than expected resulting in inefficiencies and even equipment failure due to inadequate cooling.

Underfloor pressure control is generally used to meet a specific amount of airflow and the general rule of thumb for airflow on the floor every 1 kw of server load a data. Actual measurements however showed that the open area is only 19 5. Enter a product name find. What sets this perforated floor tile apart from others is the adaptability to different access floor systems and underfloor structures.

Af320 steel air flow perforated panel. Published flow specs for tate brand tiles using 90 cfm per kw for blades and 155 cfm for 1 2 u servers. Af500 and af600 aluminum air grate. On the other hand the perforated tiles with low porosity of 25 also can significantly improve the air flowrate distribution by 88 9 with the severe pumping power penalty of 2 79 times.

The rated open area of perforated tiles is 25. Dag500 directional air grate. Floor tiles in typical data centers deliver between 100 and 300 cfm. Af320 steel air flow perforated panel.

In this paper the impact of data center design parameters on perforated tile airflow is. The infinity air grate is compatible in access floor systems up to a maximum stringer width of 1 1 2. There are basically 2 different styles of perforated tiles 25 open and 50 open grates. The temperature of the air is generally a constant coming from the crah or crac units.

Finally in a ved data center where all bypass leaks are sealed off and the raised floor joints themselves have less than 0 1 leakage then significantly higher under floor static pressure levels can be achieved for greater flow per tile thereby reducing the tile count requirement for high. P in wg 4 05 10 7q cfm 1 99 figure 2 shows the six perforated tile arrangements considered in this study. If your perforated floor tiles provide cooling air greater than 600 cfm you can use fewer tiles to cool the server. Dag500 directional air grate.

With perforated tiles considerations include the amount of cfm s needed for air flow.
