Yeah, I still don’t buy it. No data center operator is going to use almost twice as much electricity to operate their cooling system if they could install evaporative cooling towers and almost double the efficiency of heat rejection. You can remove 7W of heat for 1W of electricity with a cooling tower, it’s 4W for 1W with a closed loop system. I could see them doing it in a humid area where you can barely get any cooling from evaporation due to the air being satured, but that only covers the Deep South and Florida in the US.
I don’t care if some company operating data centers claim that they’re aiming for closed loop cooling systems when the economics favor open loop cooling. Show me the incentive and I’ll show you the outcome, the incentive to increase profit by using cooling towers will beat out the abstract good feeling you get from not using evaporative cooling towers and paying almost twice as much to reject heat from your data center which you only operate to make a profit.
