As a reverse to “Cold Aisle Corridor” (CAC) the “Hot Aisle Containment” (HAC) configuration increases cooling predictability in extreme high density environments within rack level solutions that neutralize the hot exhaust air at the rack or row level.

With the FlexAisle® Hot Aisle Containment configuration, high density technology is clustered together in two rows of cabinets within the general data centre floor space. These systems are usually deployed with “In Row” cooling units which provide cold air to the front of the equipment cabinets. A containment system is used to enclose and prevent the escape of hot cabinet exhaust air into the general data centre environment. The “In Row” cooling units will then draw the hot air back and re-circulate it as cold air to the front of the cabinets.

This approach effectively eliminates mixing of cold and hot air to maximise system efficiency. There is a neutral impact on the overall server room environment.

Advantages of the FlexAisle® Hot Aisle Containment configuration are summarised below:-

• Increased cooling capacity to maximise the use of existing data centres
• Higher Delta T resulting in increased Net Sensible cooling capacity of cooling equipment
• Comfortable working temperature for general room environment
• Neutral effect on remaining data centre space
