1. System Design Load is based on permanent set ? 0.010" and is verified by loading panels in accordance with the CISCA concentrated load method but with panels installed on actual understructure instead of steel blocks. (Testing on blocks does not represent performance of an actual installation.) Ultimate, Rolling, and Impact Load tests are performed using CISCA Test Procedures.
2. Safety Factor is Ultimate Load divided by Design Load.
Directional airflow panels maximize the financial performance of any new or existing data center. The precise delivery of air reduces bypass airflow allowing new facilities to reduce the number of CRAH units.
Retrofits can set CRAH units with fixed speed fans to standby mode or adjust variable fan drives to operate at a lower static pressure, saving energy. Likewise the 93% Capture Index eliminates the need for a full containment system. The facilities overall cooling capacity will also be improved allowing for the addition of IT equipment without capital investments on infrastructure.
Airflow Performance Information
| Pressure (in. H2O)||CFM (w/o Damper)||kW/Rack (93% CI)|
*Cooling capacities were calculated using the following formula:(CFM x Capture Index %) / 126(CFM needed to cool 1kW @ 25ºF ?T)= kW per rack.
