Scalable Solution for Critical Environments
InRow Advantages
The row-based solution improves energy efficiency and cooling ability in a number of ways. First, the InRow
DX draws air directly from the hot aisle, allowing the InRow DX to take advantage of higher heat transfer
efficiency due to higher temperature differences. It can then discharge room-temperature air directly in front of
the servers it is cooling. Placing the cooling unit in the row enables the unit to operate at higher return and
supply air temperature, yielding 100% sensible capacity. This significantly reduces the need for
humidification.
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 InRow DX allows it to be easily added in the row as the demand for cooling increases.
The additional benefit of the row-based architecture is the ability to add 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.
