R series close control air conditioners are built and sized in
such a way that they can be installed alongside data cent-
er racks In air conditioning systems for large data centers,
the adoption of the following 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 layout perfectly. As a matter of fact:
SysTemp R
•
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.
