3.3.6 Cooling and Airflow
Cooling
Cooling can be obtained in different ways, by using the cooling ducts in
the bottom and the top of the unit, by taking air in and out the back of
the unit or by combining the cooling possibilities.
Duct cooling
A dedicated option has been developed to optimize installation of IP00/
chassis frequency converters in Rittal TS8 enclosures utilizing the fan of
the frequency converter for forced air cooling of the backchannel. The
air out the top of the enclosure could but ducted outside a facility so
the heat loses from the backchannel are not dissipated within the con-
trol room reducing air-conditioning requirements of the facility.
Please see
Installation of Duct Cooling Kit in Rittal enclosures
, for fur-
ther information.
Back cooling
The backchannel air can also be ventilated in and out the back of a Rit-
tal TS8 enclosure. This offers a solution where the backchannel could
take air from outside the facility and return the heat loses outside the
facility thus reducing air-conditioning requirements.
