7.2.6 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 adjustable frequency drives in Rittal TS8 enclosures utilizing the fan of
the adjustable frequency drive for forced air cooling of the backchannel. The air out the top of the enclosure could but ducted outside a facility so the
heat losses from the backchannel are not dissipated within the control room reducing air-conditioning requirements of the facility.
Please see
Installation of Duct Cooling Kit in Rittal enclosures
, for further information.
Back cooling
The backchannel air can also be ventilated in and out the back of a Rittal TS8 enclosure. This offers a solution where the backchannel could take air from
outside the facility and return the heat losses outside the facility thus reducing air-conditioning requirements.
