Optimization of Data Center Cooling and Water Efficiency Part 2: Open Loop Cooling Towers

Heat rejection is the most consequential aspect of data center cooling design. Data centers are driven to optimize heat rejection to minimize, or even eliminate, their reliance on chillers. There is a wide range of both traditional and evolving solutions which we will explore as this series progresses. In this blog, we focus on heat-rejection via….

Cooling Tower and Condenser Water Design Part 9: Controlling Cycles of Concentration

/
Successful cooling tower operation and performance involves a delicate balance between (1) keeping the dissolved solids (such as calcium, magnesium, chloride, and silica) in the water from causing too much scale and/or corrosion and (2) conserving make-up water. It’s expensive, inefficient, and environmentally irresponsible to continuously dilute cooling tower water with an abundance of make-up water just to keep the ratio of minerals down. But how do you decide how much make-up water is needed to keep minerals within a tolerable range?
