How to cool down water?

[StevoP80]

I finally got a map with a geyser. Great! Except the water temperature is 150F or greater. If I pump this water through my base it overheats any room the pipes run through, much more than any room containing machines.

I think, ok, I'll pipe the water through an ice biome in normal pipes (no insulation) and that should cool it down before it reaches my base. Nope. Not at all. What happened was the air of the ice biome I piped my water through had its air temperature quickly go from -30F to about +110F, with no change whatsoever in the temperature of the water in the pipes.

Any way to cool down the water from geysers?

I'd suggest putting a valve on the pipe before entering your cold area, so it goes slower and in smaller droplets, but hydrofans are a thing, and with infinite water, you can get infinite hydrofan usage.

[StevoP80]

I just tried the valve suggestion. Took the volume in the pipes from 10Kg/s to 5Kg/s, and no change in the water temperature after leaving the ice biome.

Hydrofans aren't really a viable option. With the changes to electricity, I have to run more independent circuits with hamster wheels. 8/10 of my dupes already spend the majority of their days running on the wheels. Doesn't leave much time for fan operation. To do that I would have to get even more dupes for fan/wheel operation only, who will consume more food/water/o2 making them ultimately more of a resource sink than what they will be contributing to the colony overall. Some serious system balancing needs to take place, hopefully sooner than later.

as of now, there is no building too directly do this like thermal (to cool down gas).

but there are several round about way to cool it down.
the most popular one is to build a hydrogen room where you put several whezel (giant snow carrot) and coold down the hydrogen until it hit -40 celcius or lower.
and run a gas pipe through your water tank.
the heat from your gas will lower the water temperature.

another solution is cooling it down by merging it with cool water (duh? capt obvious).
you can put snow/ice (NOT POLLUTED ICE) in a storage that you build below your water tank.
once it's melted, this will cooldown your water.
this is a long proccess tho.

the faster one is you just pump in cool water into your water tank.

I've pumped some cool water into the geyser's spot and the water went from 75c to 35c and never went above it. I think it's a glitch since it's flooded and don't produce steam....

Piping incredibly cold gas through the hot water area aroud the geyser is an idea I had not considered. Sadly this will require yet another independent circuit, and a dupe or 2 to keep it powered. Time to test it out!

i dig a pit down-gravity from the geyser, and in a mineral ice cold zone. I let the geyser water run down several squares of surface to the pit.

i use the pit as sump with pump.

I use this method as well for cooling the water. Allowing it to fall a VERY long distance using gravity into a holding tank in an ice biome ( the holding tank has no top, only bottom and sides to allow the cool air in). Running the water pump with an on off switch will allow you to only pump in the water once it has cooled enough for your purposes.

I'm currently in debug mode trying out several methods. Pumping super cold gas (like -70F) has not made a difference.

So, the reason the ice biome doesn't cool when you run pipes through it is because there is too little gas there. Low gas pressure means small heat capacity means heats up too fast.

Ice stairs
My solution to this is the "Ice stairs", based on the idea that the blocks in the ice biome do have enough heat capacity. I build a large 40 - 60 diagonal stairway out of blocks running through the ice biome. I let the water run down the stairs and voila. Very rough estimate, it cools between 1 and 2 degrees per block.

Modifications
In fact, because the water starts out so hot, you don't even need to build the hottest part of the stairs in the ice biome, contact with 30C slime blocks already goes a long way.
Be sure to use blocks that have a high conductivity and possibly add coper wires from the blocks into the water for added heat transfer.

well. you are doing something wrong then.
because it works for me and other people too.

I pump it from this geyser.

I was not seeing an effect from the cold piped gas running through the water either. But when I vented the super cold gas right above the water there was a rapid change in water temperature in a large block area. Unfortunately I couldn't sustain it for long as my power source was undersized. Will need to test more. As others have said, I think building an "aqueduct" through an ice biome and letting the water flow over high conductivity surfaces might be the best bet right now.

Something weird I was seeing during my experiments and was wondering if someone could confirm, is that the carbon dioxide in the pipes was not cooling when ran through the machine. I pump a mix of gases from the geyser room out and cool it down before pumping it back in. I don't filter any of the gases out, just let it all flow. Hydrogen, polluted oxygen, etc.. all were cooled to below -30, but the carbon dioxide was around 120. Known bug? Glitch just in my game?

I cooled my geyser water in a funny way. At first, it dripped into my pool. Then right after I added mesh tiles to allow Gas to flow w/ö risking scalding on my dupes right next to ladder, it turned into a dangling booger like thing lol.

Adding myself to this, here's the information I got so far:

-Insulated and regular pipes are the same, they both output a crazy amount of heat around them, and don't allow the contents to change temperature
-Ice will ABSOLUTELY NOT alter the temperature of water in any way whatsoever. I have a 20 ton chunk of ice sitting inside a geyser-water reservoir at a toasty 75°C, it has not melted after 80 cycles being there. I also tried the container way, 3 storage compactors full to the brim with ice and snow built over mesh tiles and sitting directly inside the near-boiling water. Containers were 45°C, while contents were -22°C
-Gas piping around the pool does nothing, I have a loop running gas at -20°C inside the pool, that can't get it 1 degree cooler than its original 36.

Use abyssilite, it has zero thermal conductivity => pipes will stay cool.
With ice - use smaller chunks, like 2-3T, it will melt relatively quick, and when it melts it causes noticable temperature drop. I was cooling my water exclusively this way - add some geyser water, add some ice, do not overdo it with geyser water and it will stay at nice 20-30C.
Pumping -200C hydrogen through water cools it very effectively, and only requires single thermal regulator to run for few minutes every 3-4 cycles. Should be carefull not to freeze it though...

Here's something I've done recently that works pretty well.

Build a mesh reservoir in an ice biome and place some Weezewarts around it to help maintain the ice biomes cold temp. Then, simply pipe your super hot geyser water (using insulated pipes of course) to that reservoir.

Here I'm piping water that's 64C. The water becomes about 37C on the left side of my reservoir cooling to about 25C on the right side of the same reservoir where I pump it out for use elsewhere. So this is a good cheap low energy method to cool down water.
