Cold Aisle Containment (CAC): Encloses the cold aisle, ensuring supply air reaches IT equipment efficiently. An enormous amount of energy is used every day to maintain an acceptable intake temperature to the IT equipment. This approach transforms traditional hot aisle/cold aisle. Hot and cold aisle containment offers a proven design approach, but the choice between cold aisle containment (CAC) and hot aisle containment (HAC) depends on facility layout, cooling system design, and density requirements. At Aeons Technologies, we deliver engineered containment solutions that. Traditional open aisle data centers use perimeter PAC (precision air conditioning) or CRAC (computer room air conditioning) units to channel cold air up through a raised floor void via grilles positioned in front of the IT cabinets. This has significant disadvantages as there is no separation. n is a best practice solution that separates hot and cold air streams. However, without a physical barrier, you can still have wrap-around and.
