Quoted... "Your concept has zero merit and looks like the brainchild of an eager 14 year old wannabe engineer.
First off, you keep ignoring the fundamental issue of reinjection and pollution.(i.e.don't confuse me with facts) Are you going to guarantee a safe injection system. Second, how do you get this "infinite" supply of cold water and who guarantees the temperature and when you pump it back ,exactly where does this water go and who pays for the water you are using? Are you telling the utility you want credit for the warm water you are returning? Good luck.
And by the way what have you got against 65 year old engineers who don't "think" out-of the box like you, are they "tired"."
Response:
My mentor was 67 years old when we met. He was neither old nor tired. He embraced learning new things. Was eager to calculate them properly, and did not take the path of least resistance at every opportunity.
I was not proposing running potable water directly thru a chiller. I was proposing running it thru a heat exchanger to isolate the potable from the chiller water. There are food grade plate and frame heat exchangers. My safety intent would be to have the potable system at a higer pressure than the chillers condenser water system so if there was a leak... it'd leak OUT of the potable system. And I don't know if you have any experience in city water or not, but it's NOT that clean. They get mains that break all the time, and Joe Dirt jumps in the hole and patches it up with little to no regard for cleanliness. It's not like our water system is a sterile, hospital like system anyway. You are the one that does not want to be confused with facts pal. I'm sorry your over the hill, and I'm sorry you think you know all there is to know. Me, I do not know everything, and never will. There is always new stuff out there, and just because it's never been done, done not mean it's a bad idea. You just crawl back in your hole, and keep doing the exact same things you have been doing for the last 40 years. What's the big deal if you re-inject the water 10F hotter than you got it?
I did not think this up. I read an article about it a while back. So it had enough merit to get published in a trade journal. My intent of posting it here was simply to have a discussion of interested parties.
To answer the question of how did it turn out... I knew all along I'd never get to do it, but still like to talk about ways to save energy. We're in desperate need af saving energy now. Our world, and out engineers have been throwing more energy at problems for far too long. It's up to us (The next generation of designers) to help SAVE energy rather than squander it like our predecessors have been doing.
