Data Center High Density Cooling

Applying clean room process cooling methods to data center cooling.

This environmentally responsible technology provides real time, load based, process cooling at the rack level; eliminating the need for hot aisles and cold aisles resulting in 60 to 80% less power usage/energy savings compared to traditional mechanical refrigeration systems in Data Centers.

This is accomplished by combining:

Multistage Evaporative Cooling System (MECS)
+
Individual Server Enclosure Cooling System (ISECS)
+
Real Time Monitoring and Control System (RTMCS)
=
Real Time Data Center Cooling System (RTDCCS)

*Average Size Enterprise Data Center

  • 1700 SF of White Space
  • 60 Racks (6 rows of 10 racks @)
  • 4 KW per rack with total IT load of 240 KW

Traditional N+1 Perimeter CRAC Cooling System

  • 6 Cooling Units at 50 KW load each (5 CRACS @ 50KW =s 250 KW + 1 @ 50 KW)
  • All units turned on
  • Hot/Cold Aisle Configuration

RTDCC System

  • Cooling unit below (or above) every cabinet
  • Warm Air from every rack ducted to cooling unit under floor
  • Uniform cold air flow throughout the Data Center white space, no hot aisles
