G series close control air conditioners have constructional and operat-
ing characteristics suitable for meeting the design criteria of the latest
generation data centers.
When designing air conditioning systems for large data centers, the
need for electrical cable housing and the enormous air volumes re-
quired to cool down the servers have made it essential to increase the
height of raised floors up to the current 550/1,000-millimetre level. A
large space below the air conditioner for the installation of an adjust-
able stand has thus created. It was therefore decided to use this large
space to house supply fans.
Without increasing the footprint of the machine, and only exploiting
space where it is provided, great advantages have been obtained:
With the same air conditioner footprint, it has been possible to in-
crease the front section of the coil by about 40-50% by reducing
the pressure drop on the air side, and thus the fan energy consump-
tion.
Increasing the size of the air filters installed upstream of the cold
coil allows a significant reduction in load losses and replacement
frequency for maintenance.
Increased efficiency of the fans which, installed in the stand, expel
treated air horizontally and completely unobstructedly.
