System Design
The air flow required of the system is dependent upon the total IT load and the server design. Using a typical ΔT of 10C a single EcoCooler CREC can support a load of 35kW. The systems can be either fixed or variable flow.
The low energy air distribution system uses axial fans which can accommodate most applications. Where raised floors are used, the overall design, in particular the floor grill numbers and position, should reflect the pressure drops and rack cooling load density.
Most systems are controlled centrally. This allows fully automatic control and identification of any fault conditions.
