Keeping It Cool
Irides' Data Center uses specially designed environmental systems that regulate temperature and humidity in our
data center at all times. The Heating and Cooling system installed at Irides is designed to provide
environmental control to the server farm and other critical areas with a [N+1] redundancy.
The following applies to our Arlington Data Center:
- Chiller System: The chiller system consists of one 726-ton and one 600-ton centrifugal chillers manufactured by Trane; one variable-speed drive unit and two solid-state starter units. Each chiller in the system can act as a lead, lag or standby chiller at any time, providing for N+1 redundancy.
- Cooling Towers: Irides has a 400-ton tower cell plus one 600-ton tower cell that supplies N+1 redundancy to the condenser system. The cooling towers are designed with an automatic water treatment system to maintain the quality of the water at all times. Liebert and Trane System: The Irides data center is cooled by a 30-ton down-flow Liebert unit, and a 30-ton Trane unit. Each unit can be independently operated to provide cooling against variable and evolving load conditions, while maintaining N+1 redundant cooling to the data center
- Chilled Water Loop: The chilled water system has two separate pumping systems, a primary and a secondary pump for redundancy. The chilled water loop feeds the Liebert and Trane units, fan coil units and the air handlers in the data center.
- Monitoring System: Irides utilizes Siemens Apogee Insight Control System for real-time monitoring, as well as the command and control of every aspect of our facilities' system network. The Apogee Insight Control System provides a fully automatic control over the system, gathering data such as outdoor air temperature, indoor air temperature and quality measured separately from over 200 sensors, water temperature coming from and going to the cooling towers, chillers, air handlers, water pressure and the flow of water through the pumps, and uses this data to adjust the system as needed to maintain predetermined set points
