Hot Aisle Containment is an alternative to Cold Aisle Containment, but with the hot aisle being contained instead.
With Hot Aisle Containment the hot aisle is contained by infill panels on top of the racks that direct the hot air back into the ceiling plenum and back to the cooling system. With both types of aisle containment systems, preventing hot and cold air from mixing can provide the means to make significant energy efficiency improvements to be made, by adjusting the output of the CRAC units. EDP Europe also offers a Thermal Curtain Hot Aisle Containment solution.
Installing an aisle containment system is part of the 4R’s of airflow management, which shows how managing airflow at raised floor, rack, row and room levels, will help enable optimisation of cooling systems.
