 Our new data center upgrade summer-fall 2019. New LED lights, new ceiling. Because of virtualization we are reducing our cooling square footage. Using vinyl curtains we'll create a cold aisle (blue). Two new Liebert CRAC units (green) will discharge cold air above floor into this cold aisle. Two rows of 13 racks with servers will pull cold air and discharge into hot aisles (red). CRAC unit intake of hot air is from top. We are abandoning delivering cold air from below floor. (Raised floor only 7 inches high with all kinds of crap in there, cables, pipes, etc). Coolant gas will bypass chillers on roof if outdoor temp is 45 degrees or less generating significant savings (economizers).  The rest of the room will be normal room temperature, we call this the L-Room (brown). Automatic control dampers will supply the L-Room with some cold air to maintain network equipment. Our new data center upgrade summer-fall 2019. New LED lights, new ceiling.

 +[[https://www.vertiv.com/en-us/support/tools-applications/free-cooling-economizer-calculator/|Vertiv Free Cooling Calculator]] 80 degree return air (conservative) with 70% load rates full free cooling hours are at 44% for Bridgeport and 48% for Hartford. So the expected 40% lsted aboveis low water mark as that percentage goes up if return air gets hotter. At 85 degree it yields between 53-56%.
