G Series – Close Control Air Conditioners for Large Data Centers

When designing air conditioning systems for large data centers, the need for electrical cable housing and the enormous air volumes required 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 adjustable 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 increase the front section of the coil by about 40-50% by reducing the pressure drop on the air side, and thus the fan energy consumption.
• 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.
