> The mean air temperature on the upwind side of the facility was approximately 42.7 °C, increasing to 43.5 °C in the neighborhood near the eastern boundary of the data center campus on the downwind side. The observed ΔT of approximately 0.8 °C extended roughly 500 m downwind
Seems like we do observe heating but a much smaller average delta T than the title would hint at; I didn't see a max distance they evaluated over, seems like 500-1000m was their search window from their text. The next paragraph discusses how one of the sites they compare to is a relatively lower average temperate than the rest of Phoenix. Not really convinced by this methodology. Seems like doing something in a flat field with an array of temperature sensors would be a much more robust way to look at heating effects over some reasonable distance. Plenty of data centers fit the bill of flat and semi-isolated, curious why they chose these sites to look at
- elictronic 1mo agoThe title is correct. You are looking at average temperature rise. The article states by up to which is the maximum temperature rise. If you catch me on fire my average temperature rise doesn't go up very much, but I have the barest of hints that it might have an impact.
- duplessitous 1mo agoNever said anything about correctness.
- user43928 1mo agoNo it's not correct, because no causal relationship has been established between the data center and the most extreme difference measured. I understand that the study only showed that this was the maximum observed difference downwind of one data center during one run.
- atoav 1mo agoIt is probably better to just thermodynamically ballpark the whole thing. How much energy goes in? Some percentage of that is gonna need to be radiated out either directly as IR radiation or by pushing a heated medium out (water, air). Someone did the math on that in the construction of the data center. It is completely understandable that it is in the interest of the public to enforce some limits on the resource use, radiation, etc on any building, be it a data center or not. And these limits ideally should take local, state-wide, national and global considerations into account.
