Rittal Cold Aisle Contaiment
Cold Aisle Containment
Rittal's Cold Aisle Containment system allows you to target a specific area with cooling rather than flooding the Data Centre with cold air.
Cold air is contained within the aisle ensuring that the cold air is exactly where it is needed, directly in front of the air intake of the servers. Cold air is directed across the whole height of the enclosure ensuring that there are no hotspots and the hot air is exhausted out of the system.
Due to the cold aisle being contained there is no chance of the hot exhaust air mixing with cold inlet air.
Cold Aisle Contaiment systems are increassingly being deployed in Data Centres where the average power demand of each cabinet exceeds 5kW. Effectively using roof panels and slideable doors at each end of the row which contains the cold air within the aisle. This prevents cold air mixing with hot exhaust air and increases the capacity of the overall system to approximately 10kW per cabinet.
The other benefit of cold aisle containment is that because the cold air is now being delivered directly to the server, the cold aisle air temperature can be raised, meaning that the CRAC or LCP inline cooling system is a lot more energy efficient resulting in energy cost savings.
The special energy efficiency of the Rittal cold aisle containment concept has a simple and plausible explanation:
- Cold and hot air cannot mix, warm air does not flow into the cold aisle
- The system can be operated with a much higher extracted air temperature
- Standard air circulation cooling units are operated at an optimum thermal efficency level.
The system can also be used in reverse. Where instead of the cold aisle being contained, the hot aisle is contained, and the hot air directed through a hot air plenum back to the CRAC units.
The cold aisle containment works with the Rittal TS8 Server Racks and can be retro fitted.
