Energy Use and common sense.Less Air Volume is More Energy savings.

The less amount of air volume that needs to be de-humidified & cooled the less energy is used.

With minimal hot/cold isle isolation 491 Cubic meters of air must be cooled (note entry and closet not included in calculation).

Energy Use and common sense.Less Air Volume is More Energy savings.

With stringent hot/cold isle isolation only 84 Cubic meters of air must be de-humidified & cooled.

This equates to a 83% reduction in the volume of air to be processed.

A brief summary of the specifications on all the equipment for new projects show that with NO EXCEPTION these devices are rated for 30 degrees Celsius operation. The obtuse part is that the REAL requirement actually requires a range of 25-28 degree air at the device inlet.

Device Air inlet25 Celsius

Device Output30 - 32 Celsius

After searching all of Brocade (including Foundry), Cisco, HP, Juniper, Tanberg, Sun (now Oracle) and Cray the only system that did not specifically state operations acceptable at 30 Celsius was the Cray XK6 Supercomputer.

Energy Use and common sense.How cold is “cold enough” ?

Cover unused cabinet space

Incorrectly isolating Hot Isle from Cold Isle by leaving open blank spaces in cabinets is a major contributor to wasted cooling energy. The combination of installed equipment venting and fans create a large underfloor pressure that pushes the air out the path of lowest resistance. The majority of your cooled air passes un-utilized thru the cabinet and out the hot air return due to the pressure differential created.

Energy Use and common sense.Focus your cooling energy.
