Okay I feel like maybe I'm missing something. In a closed loop system, nothing evaporates. If you use an air cooled design, nothing evaporates.
If you use a hybrid design, you still evaporate ~80% of your cooling water - you just use less overall cooling water.
The water going back to the water cycle doesn't mean it's potable.
And yes, I do understand that it is a very small fraction of overall water use. I am actually in favor of using water where it will reduce electricity use. But let's not be inaccurate - the water used for cooling is absolutely evaporated or sent to sewage, with the exception of whatever sits inside the system's closed loop (which exists whether or not the system is cooled evap/dry/hybrid).
- theultdev 22d ago> you just use less overall cooling water. yeah... that's the point right? Hybrid systems keep the primary process fluid in a closed loop, they spray water on pads to cool the coils during the hotter parts. Basically a stop gap when air cooling is not enough. There's also close loop systems that lose none, it's just more expensive to build. They are already being deployed in areas with scarce water. Microsoft and a quite a few others already built a few.
- elil17 21d agoRight, but it doesn't make sense to say they are evaporating a smaller percentage of the water.
