I am trying to come up with a cost effective way to help my CFC bring temps down a little lower.
Has anyone tried something like this? Will it be efficient enough to work?
I apologize for this weak rendering of my idea.

My plan is to use regular water to bring temps down as far as they will go then open the valve(s) to the cooler then mixing ice cold water in the line. I don't need that much as I can get to about 80 as is.

Thanks guys and gals!

Yes, the degree of which depends on the specific design.

Yeah, one worry I had is that my Immersion Chiller is 5/8. I worry that the size reduction would reduce efficiency.

5/8 or 3/8?
5/8 is fine. Even 3/8 IMO

I assume you would run ground water through to knock down from 212-100 or so, then switch the valves and run the ground water through the iced down immersion chiller through the CFC then to waste?

Colder water will give you better cooling regardless of line size. You could probably got your wort down to 40 deg if you give it enough time. There a many people that use this system. It will, absolutely, cool your wort faster and colder than just water alone.

That's right Layne. I didn't plan on turning the ground water completely off. Just add the chiled water to the mix.
Or, whatever works, if it works.......

I've been through many iterations of chillers. So far, what I've found chills the quickest is pumping wort out of the kettle into a 25' CFC chilled with hose water, then into a 25' coil immersed in ice water in a cooler, then into the fermenter. This set-up goes from boiling to 42F in a single pass with a full throttle march 809 pump in the summer heat and warm ground water. I put a pond pump in the cooler with the ice water just to move the water around, it helps efficiency.

I don't use a plate chiller because I fear gunk build-up and I don't use a whirlpool chiller because I've clogged my hop stopper with cold break before.

I do this here in Richmond during the summer, where regular hose water comes out between 80 and 90. I use a 10lb bag of ice and a little water the entire time and I flow into the fermenter between 55 and 60 degrees in less than 10 minutes. It warms up as the ice melts and you reach the end, but the temps in the fermenter equalize out because the colder stuff went in first and the warmer stuff will balance it. Never had a problem with having to wait to pitch.

I have also set it up on a pump where I just recirc the ice water through the CFC, but that takes more ice due to the warm incoming water from the chiller.

You're right Layne, it is 3/8 copper.

You probably don't need the valve on the left, if you're looking for opinions :-). The valves integrated into your "Y" on the right will do the job just fine by themselves....water won't be able to back up into the chiller if the chiller valve isn't open on the right, so why have the valve on the left?

Also, having the valve on the left just means you have to manipulate TWO valves to control how much chiller water you mix with regular water...
