economizer mode for a liebert unit

1 post / 0 new

Hello All,

A colleague of mine is trying to simulate a data center. The center is
currently served by Liebert units (so 0 OA). He would like to try and add
some type of economizer cooling by bringing in OA when the outside
temperature is below 55 deg F. When the outside temp is above 55 deg F he
would like to shut off the OA. Any suggestions on how to model this? Is
there a way to maybe schedule economizer cooling and/or outside air ratios
based on outside air temperatures? Any help with this would be greatly
