What is the most effective water cooling method?

[Technoincubus]

Aside from nullifier?

I tried creating a hydrogen room with tempshift plates and wheezworts with radiant pipes, but it seems to NEVER gone down to 32C. It actually never cooled down even with insulated tiles.

With auatuner dipped in crude oil it reaches 175C and breaks, with hydrogen room with 4 wheezeworts near metal tiles reaches temperatures when wheezeworts wither fast.

Is there any reasonable way besides nullifierto cool down geyser water?

Carbon skimmer + water sieve combo to bring the water down to 40C (need a steady supply of CO2) then a single aquaruner submerged in pwater will bring that to 26C

In the current build, the aquatuner does not break at 175 like it's supposed to.  Also yea, the oil will get too hot eventually; you need siphon some off and run it through the refinery to turn it into petrol and reset its temperature, and replace the hot oil with fresh cooler oil.

That's limited by your sources of CO2.  You don't get nearly enough from dupes to run the carbon skimmer very much. Even a natgas gen doesn't seem to make enough to run one even half of the time.

This is true so it also depends on what you need the water for.  

If you are growing pinchas and bristles then extra CO2 like a vent or geyser is needed

But if you are feeding your dupes mushrooms and eggs then you don't need much water and CO2 from dupes and generators are enough

My current method relies on a pH2O geyser. The pH2O comes out at -10, which I run through radiant (or granite) pipes through the hot water or steam, and sieve the water with an in-line plumbing temperature sensor that shunts the pH2O to a sieve when it reaches 70^oC. The sieve has a fixed output at 40^oC, and with the insane amount of regolith (or even sand) filtering is no issue.

This could also be done with just the water from a steam geyser. Simply pump the hot condensed water through your latrines and take the pH2O from the latrines and run it in a radiator pipeline through the geyser room, condensing the steam. Filter the heated pH2O, or dump it somewhere. Since you won't be using this filtered H2O for any foodstuff, it doesn't matter if you electrolyze it or use it in latrines

Note that this method does not bring the water below 40^oC. For sleet wheat farms, 40^oC water is fine, so long as you also run an AETN with a hydrogen radiator. The sleet wheat don't care what temperature the water is, so long as the PLANT is below 5^oC. Use high pressure oxygen and tempshift plates with radiant pipes.

For bristle blossoms, I use an aquatuner to bring the water below 30^oC. I rarely need bristle blossoms beyond cycle 100, so it's not worth the power draw.

Sieve and skimmer is a heat deletion, and thus unreliable as it could be fixed. And carbon is extremely unreliable as well.

I don't think so.

All machines generate heat while regulators and tuners only displace heat.

In order for the game to be more balanced there needs to be a way to delete heat as well so I don't think they plan to change the fixed temp output of sieves and skimmers.  If they were then they would have done so a long time ago

You can use steam turbines, coupled with aquatuners, to delete heat in mass quantities and gain power. Here is a screenshot of such an application.

This setup powers 2 aquatuners with 100% uptime, and gets you 1600W of bonus power. 

Here are two places to learn more.

Yea, I'm looking into doing that now since the skimmer + bathroom loop isn't keeping up with my heat deletion needs anymore.  That however, is clearly a bug since the aquatuner says it is supposed to overheat, and used to do so.  I just hope when they fix it they let you make an aquatuner out of tungsten or steel so you can still run it to at least 500 F.

The first link, the Steam Behemoth, was created prior to the aquatuner overheat bug. There are two ways, or more, to avoid th aquatuner overheat bug.

1. Use the temperature clamp of a gold liquid tepidizer to reset the temp to 125C. Requires a single save/reload after building the gold tepidizer to utilize.
2. The output temp of 159.1 C can keep an aquatuner (processing crude oil or petroleum) from overheating. Just use tempshift plates to spread out the heat, and you can keep it running full time without ever causing the aquatuner to pass 175C.  Once you put water in, you can't keep it running full time on 10kg packets (but you could use automation to send 10kg packets through ever other second).

As another alternative, plop a gold regular battery next to your aquatuner (which is submerged in 1 tile high of liquid). Place one tile between them, and put a tempshift plate down above it so that it touches the aquatuner and the battery backgrounds. Then let the temperature clamp (75C) of the gold battery keep the aquatuner from overheating. Works best if the gas is pressured hydrogen. The temp reset feature (bug) of the battery will keep everything cold. In another post I used this feature to cool 8 aquatuners, running full time. You could probably cool 25+ aquatuners, running full time, with a single gold amalgam regular battery.

Yea, but those are definitely exploiting a bug.  The turbine is at least supposed to delete heat and generate energy with it, it's just that you can't build an aquatuner out of steel or tungsten or something so that it should be able to get hot enough, which seems like an oversight or just dumb design.  I mean, surely you aren't only supposed to be able to use the turbine with magma right?

Base cooling is like that, gravitational hydrogen with some small blobs of accidental O2. Radiant pH2O waterpipes. Unfortunately, all the wheeze in my map do not outproduce the heat generated via steel production + electrolysis for 90 duplicants, so I have an extra aquatuner water-sieve cooled aquatuner, to keep the radiating liquid below 27C. At the moment, heat is above 30C, but crawling down.

I copied the hydrogen on top of your base idea from QuQuasars screenshots. Its a very intuitive and generally applicable cooling base, to start with.

It is kind of boring that we have to explain this again and again. Anyone who knows the patch history of ONI and how the configuration of fixed/dynamic temperature output buildings looks like knows that fixed temperature output is quite *literally* intentional and certainly not a bug nor an exploit.

Not to mention that it is also currently the most powerful intented way of cooling aside from dumping gases/liquids into space, which isn't feasable for large sustainable bases. Perhaps it is with Rocketry since you can bring down more and more ressources to your asteroid.

Another point is that the other cooling methods, such as deleting heat via Wheezeworts and AETNs is not only comparatively weak but also quite basic. The setup for these are very simplistic and leave little room for optimisation and customisation in comparison to fixed temp solutions, which require you to build multiple liquid reservoirs (not the prebuilt/building ones) temperature automation, conversion flow automation and a piping architecture. The other method, which was similarly powerful was polluted water boiling, which I personally preferred (was more fun) but that is now taken away with the specific heat capacity change of polluted water from 6 to 4 (same as steam/water).

That said, yes it might change in the future, but as @Neotuck mentioned this would require an overhaul of current cooling methods if Klei wants us to be able to have powerful cooling solutions for the mid and possibly late game that is effective enough to handle plant irrigiation, large powerplants etc.
