Scalable Solution for Critical Environments

InRow Advantages

The row-based solution improves energy efficiency and cooling capacity in a

number of ways. First, the Uniflair

TM

Direct Expansion InRow unit draws air

directly from the hot aisle, taking advantage of higher heat transfer efficiency due

to higher temperature differences. It can then discharge room-temperature air

directly in front of the servers or IT applications installed in the room. The In-Row

configuration allows the unit to operate at higher return and supply air

temperatures, reaching 100% sensible capacity. This significantly reduces the

need for humidification.

HOT AISLE

Scalable for High Density

The predictable performance of the row-based architecture makes it well-suited

for high density applications. The focus on heat removal instead of cold-air

delivery is the key to making this approach scalable. The modular design of the

Uniflair

TM

Direct Expansion InRow unit allows it to be easily added in the row as

the demand for cooling increases.

The additional benefit of the row-based architecture consists in adding hot-aisle

containment. Containing the hot aisle further reduces any chance of hot and cold

air streams mixing. This provides ultimate predictability and allows the cooling

capacity to be matched to the IT heat load.

EcoAisle

™

aisle containment system

Modular ceiling tiles and doors/curtains can be used to enclose the hot aisle. This

increases the densities that can be handled in a single rack enclosure by

eliminating mixing of hot and cold air streams. This method, called load

neutralization, removes the heat from the hot aisle, cools it, and then returns it to

the surrounding room area. The warmer return air temperatures that are achieved

in this application increase the capacity of the air conditioner and, in many cases,

eliminate the need for make-up humidification.

Use of modular ceiling tiles across a 3- to 6-ft. hot aisle that connects two opposite

rack enclosures makes expansion quick and simple. Expansion kits, with the
