Compact, Efficient Cooling Technology
The technology deployed means that the free cooling thresholds have been raised, even in the more compact models.
Open Aisle containment was found to require 51% requiring mechanical cooling with only 1% in complete free cooling mode. Whereas in the ‘Cold Aisle’ where supply and return air temperatures are elevated, only requires 32% of the year in mechanical mode with 6% with complete free cooling.
In hot aisle and inRak mode, 25% of the year was serviced by completely free cooling mode.
The Echo compact hot aisle containment mode of cooling was able to provide 89% of the year in free cooling mode.
An active cabinet exhaust draws air from the hot aisle at the back of the cabinet, discharges it into a ceiling plenum, where it can be cooled by precision air conditioning units at the periphery of the room.
