    I have been searching forever to find a simple schematic as to how an open and closed hydronic cooling works. Excuse my newbie question, but I have a project I am trying to put together and I can't get a grip on how these systems work.

    I think I have good foundation on the principles but not the overall flow of the different loops from the cooling tower, chiller, condenser, etc. If someone has a link or pdf that would be fantastic. Thanks for any help.

    Are you talking open and closed cooling tower or an actual chilled water loop? I've seen a couple open chilled water loops in a industrial process application but have only seen one open chilled water loop in a comfort cooling application.

    also when you used the word hydronics, the first thing that comes to mind is a boiler loop.
    use the terms chilled water and condenser water loops, while doing research and you may get better results.

    I have been to both of those sits, but did not find a graphic or flowchart as to how the systems operate. I will try the verbage you suggest and see what I get. In the mean time, I have found this

    I did not want to post someone elses work so I just pasted the link. It's a great picture but I was looking for something a little more 2D or technical.

    if you feel like spending $140.00 , go to amazon and buy HVAC water chillers and cooling towers by Herbert W Stanford, easy to read and good for all the basics

    I found hydronic piping diagrams on jhonson controls website. It was hard as heel to find but it clearly demostrated numerous piping loops. good luck.
