  • Thom: Now, onto our presentation. Ron Spangler is a Senior Product Manager for the Liebert Precision Cooling Business of Emerson Network Power. Welcome, Ron. Ron: Thanks, Thom. I’m happy to be here today. (ad lib) Thom: Ron, tell us leveraging economizers to take advantage of free cooling in your data center. Ron: Sure, today, we’re going to talk about economizers, and really- &lt;push next slide&gt;
  • … Outside air introduce directly into the data center.
  • … about 55 degree water temperature coming out.
  • … use the fluid cooler to create our cold water.
  • ..but if we look this in the winter time and put an economizer in place
  • … from the cooling tower.
  • … We also increase the chiller efficiency, and I’ll take a look at that in a moment, next slide.
  • … if you have a question for Ron, please submit it in the Questions box now. START VIDEO
