R series close control air conditioners are built and sized in such a
way that they can be installed alongside data center racks In air con-
ditioning systems for large data centers, the adoption of the follow-
ing design concepts has in fact become an established custom:
The racks containing servers are increasingly positioned according
to the Hot Aisle and Cold Aisle layout.
Air temperatures are allowed to rise up to 30-35°C in the hot aisle
and 20-25°C in the cold one, with very low humidity (never above
30%).
Server performance is increasingly on the rise, while server sizes
are increasingly reduced. As a result, many more servers can be
installed in a rack, so some of these racks can be eliminated as
they are empty. At the same time, heat dissipation increases,
thereby requiring more power from air conditioners. R series air
conditioners are designed and built so as to fit into this plant lay-
out perfectly. As a matter of fact:
They exploit the space left free from racks and allow cold air to be
distributed as close as possible to servers, that is, where heat is
generated.
They feature rear intake from the hot aisle and front supply to
the cold aisle with a horizontal flow. The horizontal flow reduces
internal pressure drop, with a consequent reduction in the power
draw of the fan.
