how do i use aquatuner properly

[snuggleform]

I've looked at old guides/videos that abuse an old mechanic where water sieves always output water at 40C, but with that abuse out of the way how do you guys

a) set up an aquatuner system that cools liquid from 60 C down to 20C (i.e. does this take some kind of automation loop that resends liquid through the sqautuner muitiple times to get it down to the right temp)

b) cool down the aquatuner itself? Preferably do not use the AETN to do this, and preferably not a short term solution putting the plumbing through ice biome. Is there some kind of solution using a small number of breezeworts or something else relatively affordable?

The siplest is usually the best, I've found:

The steam turbine is the intended heat deletion machine nowadays.

I don't know what I'm looking at, can you explain a little bit? I don't mind going for steam turbine if that's part of the setup.

Added notes for you:

I'm using doors for the heat exchange room, but you can run the pipes straight through the thing you want cooled too.

When adding liquid to the loop make sure you do it before the aquatuner, because it has a spin up time so if you overfill the loop it will get stuck.

Well, basic cooling loop implementation is like this:

Cold room on the left side, hot room on the right.
You circulate some coolant chosen based on what temperature you need, you set coolant temperature with thermal sensor, bridges are aquatuner bypass (coolant continues to circulate with aquatuner off). The more coolant you get into the system the more precise temperature control will be, just do not fill the tank completely.
Then you put things you need cooled into cold tank (anything from water to sour gas to farms) and it will be very precisely temperature-controlled (to the point when such system can keep wheat farm which is being fed 95C water within required 0-5C just fine).
On the hot side you need some way to get rid of all the heat moved there. Again, could be anything from dumping ice there to planting whole bunch of wheezeworts to using steam turbine. Just make sure that room has high enough pressure (or some liquid) for aquatuner to be able to exchange heat effectively.

@heidnig I'm stupid I still don't get it. The only notes I understood was "temp sensor turns off if temp is too low." I don't understand "heat exchange room" I don't get "tile on return" and I don't know why you have exactly 2 aquatuners; is more or less recommended?

@L37 I'm still trying to understand - but first things first, do you have to have a setup in space like your picture suggests?

Nope, i just used it because it is clear and i do not have to delete all the stuff first.
However you obviously will have to use insulated tiles for both hot and cold parts.

Heat exchange room is basically just where the heat exchange happens. Something you want cooled comes in contact with it and warms it up. Your cooling liquid runs through it to cool it back down. I am closing the doors to make contact with the room above, but you can make it larger and run a second pipe through it with the warm liquid/gas, or use any other form of making contact.

The tile is the radiant liquid pipe at the bottom of the steam turbine. The steam turbine does not delete 100% of the heat, so it heats up a little. The easiest way to get rid of this heat is simply to use the same cooling liquid from your main loop.

The second aquatuner is for a second loop. Two aquatuners is too much for a steam turbine to handle, but I'm not running them 100% of the time so it's fine in my case. You will want just 1 aquatuner per steam turbine to start with.

With respect to this quote

"The more coolant you get into the system the more precise temperature control will be, just do not fill the tank completely."

What happens if you fill the tank completely?

Sorry still trynig to make this work, I want to try it on a much smaller scale with breezeworts first.

Well, the tank is there for 2 reasons:
- because of how it works in ONI whole tank contents have the same temperature => when there is a lot of water in (few T) few packets from pipes, even when significantly colder or hotter, will affect its temperature (=> output temperature) only a tiny bit, allowing very precise temperature control despite aquatuner's "-14C or nothing".
- overflow tank, performing the same function as such in any liquid cooling system in real world. Main reason why it is needed - when aquatuner is turned off whole loop becomes few segments shorter effectively, those few packets of water need some place to go or whole system will stop working. They will go into the tank, if there is enough free space in it...

Also, mid-game practical implementation:

It's a mess, that's why i thought it would be better to show the simpliest version possible built in sandbox...

Or just use an AETN to get started, it's simpler?

With something likie the AETN (or even the aquatuner) how much surrounding liquid/gas do you need immediately touching the heat-remover? Does just 1 tile cut it or do you want more tiles to touch a bigger surface area for the cooling loop? What's the ideal amount of "cooling" loop you want to touch the AETN or tuner with?

Idk about "ideal", but practically the bigger the loop is the less radiant pipes you need, but also the more space.

Depends. 1 tile can be enough if you are cooling a gas like o2 and don't need it at like -20. If you have only 1 tile you should insulate the aetn so it doesn't have to cool down the surrounding ice biome, because it will get very much colder.

As a general rule the worse thermal contact between coolant and what you want cooled the bigger the temperature difference has to be. Nullifiers will stop working at around -170, and for aquatuners any coolant has some freezing temperature, so keep this in mind. If you can't afford radiant pipes use snaking granite pipes.
