  • What is the function of hot aisles in the computer room

    What is the function of hot aisles in the computer room

    Hot aisle containment captures hot exhaust air from server equipment and directs it back to cooling units through physical barriers like doors, panels, and ceiling systems. When implemented correctly, they improve efficiency, reduce energy consumption, extend equipment life, and enhance overall reliability. How does Hot Aisle Containment work? As the name suggests, a hot aisle containment system. 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. By preventing the mixing of hot exhaust air with cold intake air, these hot aisle containment data center systems keep data centers running smoothly. Hot aisle containment (HAC) and cold aisle containment (CAC) are the most efficient ways of preventing your servers from overheating and these systems are currently being used in data centers all around the world. Computer servers will generate much heat when they are operating. The HAC system directs the upward airflow to an AC return system such as a drop-ceiling void.
