Anti Entropy Thermo-Nullifier questions


Recommended Posts

So I dug up an AETN (I'll just call it that for short). I'm hoping it could solve some of my overheating woes but the description and the Wiki aren't very helpful, so I have a few questions about it before I waste ages to do the wrong thing with it...

1 - It says it cools when submersed in hydrogen, yet it has a hydrogen intake gas pipe. Which is it, or do you need both? Does it consume the hydrogen it is immersed in/fed?

2 - Can I submerge it in water? I want to use it to cool my hot water.

3 - If I can't submerge it in water, will it generate enough cooling for me to put a water tank by it and the cooling effect will pass through the walls? Or would I need to run pipes with good heat transfer near it instead?

4 - I don't know about thermodynamics in this game. How long do things take to cool/heat up. If I am just pumping water/gas nearby it, will the substances have enough time to cool?

Cheers!

1. The wiki is wrong. It just needs hydrogen intake (10g/s, so not very much)

2. No; it will flood. Use it to cool gases.

3. It cools a lot, but not enough to cool an entire geyser to farm levels (you don't need to do that anyway though). It could cool a little bit though. Put it in hydrogen next to a water tank with granite or metal walls; insulate the rest of the structure

4. Just using a radiator (pipes) may not be enough; maybe if you use a valve to restrict the water flow through the pipe then it would work. As Neotuck said though, you have to be precise or the water may freeze.

Cheers folks. So why are you recommending I immerse it in hydrogen when I'm already going to be feeding it hydrogen through the intake pipe? Hydrogen carries cold better than other gases?

Also I have never understood what tempshift plates are good for, could you explain a little what you are using them for in your screenshot Neotuck? Thanks.

Two main reasons:

1) Hydrogen has good thermal conductivity and heat capacity, which makes it very good for cooling things (high conductivity means it will take heat faster from hot things, high capacity means it will take longer for it to heat up itself and require re-cooling).

2) Hydrogen has a VERY low condensation temperature. Note that the AETN will stop working if the gas it's surrounded by gets cold enough to condense. Using hydrogen lets the AETN run until the gas gets very very cold, making it usable for cooling basically anything else.

The AETN had a limit added last update, it stops cooling when the temperature reaches -170C

that limit goes as far back as thermal for sure

there is another limit, the liquid point of whatever gas you have in there, the reason for the -170 limit is to prevent the aetn from making LOX

I suspected that was maybe the reason for that limit while I was working on getting LOX production going recently. Is there any compelling gameplay or mechanical reason to make it hard to liquefy oxygen? Because given how useless LOX seems to be as a coolant, I don't really see the point of making it difficult to create.

Uh...  you mean Thermal Update?  That's not possible.  I started in Agriculture, there were no AETNs then.  They were added in or after Oil.  The "underheat" shutoff for AETNs was added in Tubular.

The point is to clean polluted oxygen without using sand.  By doing this, you can make a truly sustainable base.

There's a much easier way of converting polluted oxygen into normal oxygen without trying to super cool it

Polluted oxygen > pufts > slime > distillery > algae > deoxydizer > oxygen

That really seems easier to you than

Polluted Oxygen > Liquid Oxygen > Oxygen ?

One of those methods has a lot less steps :)

Also making LOX is fun, and it's also fun to find ways to use the LOX where you benefit from the spot cooling plus you get the breathable O2 as a bonus.  I never regret making Oxygen condensers :)

I would also throw out the thought that you become bottlenecked based on the number of Pufts the map provides you with in order to go that route.  Not to mention the Aerial Creature Lure gymnastics you must perform to actually collect them in the same place in order to use them efficiently.

I love AETN. i alway use one for oxygen cooling for my dupes, one for oil presses. If i got lucky find one more i like to cool natural gas and cool my generators while they use the cold natural gas. Such a handy thing.

What?  Why would you go to the effort of setting up an AETN to cool your natural gas generator complex, when a natural gas generator complex is a much more powerful source of cooling than an AETN?

The AETN is one of the best ways to get the Gas generator cold. No need to cool the natural gas in the first place though.

The Gas generators themselves can't really drop below -50C or the CO2 will mess up inside the pipes.

While I agree that it wouldn't be that effective for cooling the NatGas Gens, it would be a good way of "priming" the cooling effect, by getting the Gens cool in the first place.

or you could melt one small piece of polluted ice to easily get enough cold pwater to prime the effect, a much quicker and more portable solution to that problem. Whatever floats your boat, though, it's all good.

Yes, but that limits you to the number of pufts you can capture.  I personally hate herding pufts and avoid it when possible.  I find it easier per unit mass of oxygen to liquify.  Plus, then you need less morbs.
