WHAT IS HOT AISLE CONTAINMENT
Hot aisle containment consists of a physical barrier that guides hot exhaust airflow back to the AC return.
Hot aisle containment (HAC) takes advantage of the natural properties of warm air rising. The HAC system directs the upward airflow to an AC return system such as a drop-ceiling void. The HAC can increase cooling efficiency by 30% or more. Several cascading adjustments include temperature and RH set points, lower AC fan speeds, and an increased chilled water set point.
COOLING EFFICIENCY SAVES COSTS
Hot Aisle Containment can double the cooling capacity
Hot aisle containment (HAC) increases the effectiveness of your data center cooling. HAC keeps hot exhaust air emitted from server racks separated so that it returns to the AC coil both hot and dry (low relative humidity) increasing the AC’s cooling capacity. Through HAC, the hot air is given a separate pathway back to the AC intake without mixing with the cold air. In some cases, by containing the hot air and having it hit the AC coil at the hottest temperature possible, it can double the cooling tonnage.
Hot Aisle Containment can double the CRAC/CRAH cooling capacity.
KEY BENEFITS OF HOT AISLE CONTAINMENT:
- Separates supply and return airflow which provides a uniform and predictable to both IT temperature and AC equipment.
- Eliminates hot and cold air mixing
- Works in both a raised floor and slab environments
- Increases cooling capacity
- Saves energy and improves data center cooling efficiency
