For good air distribution it is recommended to
keep width of the cold aisle as small as possible
for single row server room. Otherwise the cold
air discharged by Liebert CRV unit is being led
far from server suction and hot air may by-
passed from hot aisle.
Exceptions where wider cold aisle may be used
are: applications with CoolFlex (Cold Aisle
Containment) or with two rows facing each
other.
For width of the hot aisle there are no prefer­
ences, there is just minimum requirement
needed for enough for service area*.
