The myth of the 15-ton compressor

For those of you that don’t know I started in the industry¬†as a facilities technician, then within three months became a site lead mechanical engineer. One thing that always perplexed me was the persistence of the 15-ton (or any nominal sized refrigeration component) compressor. Even today, working as a regional engineer over 3000 miles of data center footprint, I still deal with this from people who should know better.

The Hidden “U”

Shocking Revelation: Containing and controlling your airflow is crucial to optimizing the performance of your data center cooling.

More Shocking Revelation: Many data centers spend hundreds of thousands of dollars on physical separation, yet fail to blank what I call “The Hidden U”.

Immersion cooling: That’s how I learned Portuguese that one summer, right? (updated)

No, not quite. Immersion cooling has been around for a long time. Most commonly, you might recognize the large fins on utility power transformers. They are cooled by immersion, with the heat radiated by those fins. Its only recently, perhaps the past 15 years, that the concept has been applied to personal computer cooling mainly by hobbyists trying to do something different and cool, but ultimately likely being a little disappointed as other more mainstream technologies gave them their “bleeding edge” computing performance. Even more recently, this concept has started to be applied to data centers. Continue reading Immersion cooling: That’s how I learned Portuguese that one summer, right? (updated)
