Optimization of Data Center Cooling and Water Efficiency Part 5: From Heat Rejection to Heat Recovery

Optimization of Data Center Cooling and Water Efficiency Part 5: From Heat Rejection to Heat Recovery

For decades, data center cooling has been designed around one core assumption: heat is a problem to remove. Servers generate it, cooling systems collect it, and mechanical equipment rejects it to the atmosphere. That approach is essential for protecting uptime, but….

Optimization of Data Center Cooling and Water Efficiency Part 4: Sourcing Water You Don’t Have to Buy

We’ve talked about ways to reduce data center water consumption through non-evaporative and hybrid heat rejection. Even so, it is unlikely that data centers will abandon evaporative cooling altogether. It is too effective—and often too economical….

Optimization of Data Center Cooling and Water Efficiency Part 3: Closed Loop Heat Rejection

While many existing data centers use open cooling towers for heat rejection, most newly built centers are opting for less water-intensive strategies. Closed-loop systems (including heat rejection) are becoming increasingly common, especially in….

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

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….
