Immersion Cooling
Immersion Cooling Immersion cooling is an advanced thermal management method that submerges computer hardware directly into a specially engineered, non-conductive liquid to keep it cool. Unlike traditional cooling systems that rely on air or liquid flowing through closed loops in pipes and heat sinks, immersion cooling works by allowing heat to transfer directly from electronic […]
Data Center Water Management
How much water do Data Centers use? In 2025, data centers have become an integral part of our technological landscape, and their water consumption is emerging as a critical environmental concern. Data centers underpin everything from cloud computing and streaming services to artificial intelligence and machine learning and they may require enormous volumes of water […]
Energy Efficiency and Increasing Data Center Temperatures Without Risk
Energy Efficiency and Increasing Data Center Temperatures Without Risk Even when ASHRAE Technical Committee 9.09 released the Thermal Guidelines for Data Processing Environments, a path to improve efficiency was laid out to be followed. And with each update additional energy savings could be found as the group found that IT equipment was becoming much more […]
Avoiding Overcooling in Data Centers
Data centers are known for their voracious appetite for energy, with cooling systems often consuming a significant portion of this power. While maintaining optimal temperatures is essential for safeguarding equipment and ensuring reliability, overcooling leads to unnecessary energy expenditure and increased operational costs. The challenges of overcooling in data centers and strategies to mitigate its […]
Densification: Power & Cooling
Another option that continues to grow year-over-year is not going up or out at all, but solving the need for more compute by increasing IT density. The computing power density has risen from 5 kW per rack a decade ago to an average closer to 15 kW per rack for today’s new data centers. The […]
Adding Cooling
There are a number of ways to effectively and efficiently cool a data center. Below are some considerations when looking to add cooling to your critical space. Strategy: Understand the cooling methodology for your data center: air and/or water; raised floor; hot/cold aisle; containment; perimeter cooling; localized cooling; liquid cooling; etc. Establishing a new cooling […]
CRAC vs. CRAH
I had this come up recently… what is a CRAC (pronounced ‘crack’)? What is different from it than a CRAH (pronounced ‘craw’ or ‘cray’)? CRAC = Computer Room Air Conditioner A CRAC is often thought of as having an internal compressor, thus not needing the support of a centralized chilled water system. But this also […]
What do we want from CFD?
Computational Fluid Dynamics (CFD) analysis of data centers has been going on for some time, but how does it help us? For an existing data center, do you want a CFD model to show you things you already know, such as hot or cold spots? 90% of the time we are using a CFD report […]
Cooling Tower Water Storage
When operating your data center, often there are backup measures to keep things running during a power outage. Generators may be the first thing that comes to mind, as they bring power back during an outage, but along with that the cooling systems also need operate. As the heat is rejected through the mechanical systems, […]
Warmer Chilled Water on Existing Systems
So we are looking to save energy, and one of those ways is increasing the chilled water temperature. But how does that save anything? Increasing the chilled water temperature brings it closer to the condenser water temperature and thereby reduces the amount of work (lift) a chiller has to perform. Since the chiller usually has […]
