How to Model Data Centers in eQUEST

Hello All,

I'm wondering what kind of success people have had with modeling data centers in eQUEST, specifically for evaluating retrofit measures like hot aisle containment, DAT reset, increased cold/hot aisle temperatures, etc. How did you set up the zoning for the data center? What system types were used to model CRACs or in-row coolers? What kind of adjustments were made to accommodate having both overhead diffusers and CRACs?

I'm considering an approach of creating a separate zone for each hot/cold aisle and then adjusting the U-value for the walls between them to simulate improved containment. Sound like a plausible strategy or is it overcomplicating the issue?

Any feedback is much appreciated.

Thank you,

Joe Bliss

OK - here's an idea from far left field (or is it right field?).

Essentially with the hot/cold aisle what you have is the equivalent of heat being transferred into your return air stream or plenum. Currently I don't think there is a way to parse this out with equipment loads in eQUEST. You can do this with lighting loads though. How about if you modeled a second lighting load with a separate meter and schedule and assigned a portion of the heat gain to the return air stream?
