Designed by cold aisle function and structure, cold aisle skylight is a high seal, multifunctional skylight for data center cold aisle containment. While advanced cooling systems like chilled water plants and CRAH units play a major role, one of the most effective strategies is much simpler: controlling how air moves through the data hall. Beyond implementing basic measures such as sealing moisture out of the data center and improving air flow, aisle containment to prevent the mixing of hot and cold air stands out as a method that can dramatically reduce energy costs, minimize hot spots and improve the carbon footprint of data. The hot aisle /cold aisle data center layout was originated by IBM in 1992 and it is one of the oldest ways to save energy in the data center. 1 Hot aisle/cold aisle layout involves lining up server racks in alternating rows with cold air intakes – the fronts of servers – facing each other (the. The system simply aligns server fronts (air intakes) toward a shared cold aisle, and backs (exhausts) toward a shared hot aisle. Cold Aisle: Rows of racks face each other, forming a corridor where cool air is directed. Hot Aisle: Exhaust air from servers is pushed into a separate aisle, which may. Hot and cold aisle containment is a proven strategy to optimize airflow, reduce energy costs, and improve cooling efficiency.
