6. Installation
6.1 Positioning the unit
CyberRow units work in open loop architecture, between a hot and a cold aisle. For a higher energy efficiency of
open loop applications, please consider the following recommendations:
• Minimize mixing of hot and cold air between the aisles at the end of the server rows and on their top. The air di-
scharge from CyberRow units is already designed to reduce this mixing. However, where necessary, air deflectors
in critical positions give some additional help.
• For the same purpose, provide blanking plates to close free spaces inside server racks.
• CyberRow units have air discharge at both lateral sides. Therefore they should be installed between racks. Instal-
lation at the end of a row cause a waste of cold air on the side without racks. Should this application be necessary,
it is recommended to close the air discharge opening to that side. Closing plates are available as accessories.
As an alternative to close the row of units, a unit with frontal air delivery is available as option.
• Install air conditioning units near the racks with the highest load.
Overpressure of cold
air blocks warm air
recirculation
Waste of cold air: close the
lateral opening
Alternative when the unit is at the
end of a row: frontal air discharge
Only for CW size 2 units: by closing one lateral opening, the airflow supplied by the other opening
causes an underpressure of nearly 70 Pa at the air intake of the server rack next to the unit. For the
aspiration of cold air, the fans of this server rack must have an available static pressure of 70 Pa
minimum.
