Question
How does the HPE Adaptive
Rack Cooling System unit
control humidity?
How is IT equipment protected
from water when using the HPE
Adaptive Rack Cooling System?
What will happen if water stops
flowing to the HPE Adaptive
Rack Cooling System?
Can I install an HPE Adaptive
Rack Cooling System to an
existing rack in my data center?
Can I cool more than one rack
with one HPE Adaptive Rack
Cooling System?
Answer
The HPE Adaptive Rack Cooling System is not set up as a humidity
control device. Depending on facility water temperature vs room
conditions, the HPE Adaptive Rack Cooling System might remove
some humidity from the room through the condensation control
system.
The HPE Adaptive Rack Cooling System is physically separate from
the IT racks. Facility water enters only the HPE Adaptive Rack Cooling
System and runs through the cooling coil. Any condensation formed is
gathered in the condensate tray at the base of the unit and directed to
facility drains through the gravity drain or condensate pump. In the
event of greater water flow than what the condensate pan can handle,
the HPE Adaptive Rack Cooling System contains overflow switches
that shut off the HPE Adaptive Rack Cooling System isolation valves,
stopping facility flow and triggering an alarm.
There is a configurable low flow alarm that can be setup on the HPE
Adaptive Rack Cooling System. The system can also be configured
with a discharge air temperature alarm. With the automatic door
opening kit, the HPE Adaptive Rack Cooling System can also be
configured to open IT rack doors when HPE Adaptive Rack Cooling
System discharge air temperature exceeds a critical threshold.
No. The HPE Adaptive Rack Cooling System connects to specific
racks that support front and rear extensions.
Yes. The HPE Adaptive Rack Cooling System can cool one to four
racks, up to two on either side of the HPE Adaptive Rack Cooling
System.
