2) Distance between the ends of rows and walls
For single row application with one Liebert.CRV unit it is not preferred to put the unit at wall because of not proper air
paths and possible hot spots at furthest racks, unless in combination with CoolFlex (cold aisle containment) or in
application with more Liebert.CRV units. The best approach is to keep a gap between at least 0.65m or to use more
Liebert.CRV units. Good approach is also having wall at the furthest rack.
Please refer to the following sample case study comparing various Liebert.CRV positions. The CFD analysis result is
shown in Figure 2-5.
