Manage cooling problems efficiently with intelligent energy management. Achieve significant energy savings by optimizing cooling controls with supervisory systems and learning algorithms, leading to a quick return on investment. Case studies demonstrate substantial reductions in energy usage and cost savings through wireless temperature monitoring and control strategies.
E N D
Cooling problems • Server manufacturers specify inlet air temperatures • Conventional controls don’t measure it • Overcooling • Inefficiency • Hot spots
Cooling control is difficult • Open plan design • All cooling units affect all areas • Redundant cooling units • Can lead to “fighting” • Custom control software is expensive and unreliable • Can’t have a PhD commission every datacenter
