Hot aisle/cold aisle containment is a cooling strategy that isolates hot exhaust and cold intake to improve cooling efficiency and reduce energy use. In a CRCF, equipment pushes hot air out the back and draws in cooler air from the front. Without containment, hot and cold air mix, creating hotspots and making the cooling system work harder. Containment uses barriers—such as panels, doors, or curtains—to keep the cold air in front of the equipment and collect the hot air separately for return to the cooling units. This separation improves heat transfer, allows higher supply air temperatures, reduces fan and chiller energy, and lowers overall energy consumption. It’s not about labeling, security, or humidity measurement.
