Temperature management: Tutorial nuggets : Oxygen not included

[@Gr_ywind]

And this is where the learning cliff becomes a mountain.

[@Hedning1390]

There are two rules: 1 Aquatuner moves heat. 2 Anything hotter than 125°C goes in steam below a steam turbine. It really isn't that complicated. His aquatuner bridge bypass and heat regulation with doors are not required, so it looks a little more complicated in the video than it has to be.

[@MuhGuy]

@@Hedning1390 As a nooby i must ask: what would be an aesthetic(-ish) alternativ? Or any alternativ at all? :)

[@dsch772]

@@MuhGuy What do you mean by that?

[@Hedning1390]

@@MuhGuy For the doors you can just cut that step out. Doors are easier to use than pipes in some very specific circumstances. His example with the magma oil boiler is one such. However it's not something a new player has to bother with. Doors are more fail safe though. If for example you lose power a door can still open and stop the heat flow. However if you are heating your aquatuner coolant and power stops for a long time the coolant can heat up until it vaporizes, damaging the pipes. As for the bypass its purpose is to keep the coolant flowing so that you don't have to measure temperatures in several different places should you have many hot-spots. I prefer to use something similar to 20:40, ie a short loop for the aquatuner and one or several large loops going through the "ice box", but with a loop and pipe thermo sensor instead of a pump and valve feeding the tuner like 24:06. Basically 24:06 for controlling the tuner and the 20:40 loops instead of the door.

[@MuhGuy]

@@dsch772 Well i thought that doors outside of there actual ment use, looked kinda ugly - like as flowdy~tiles underneath a waterreservoire... And in most builds they (i didn't know open doors couldn't let heat travel through) they sticked out like a sore thumb to me, so i always look for alternativs.

This game is just endless learning. I have 400 hours on this game and I still have never touched the space biome or other planets. Not because I couldn't force it, but because I wanted to build a self maintaining colony with what I had first. Or at the very least, a very easily maintained colony. I think I'm just about there now, but I have to restart again so my oxygen isn't such a hindrance anymore. Heat used to be my demon, now that I know how temp shift plates work as well as liquid cooling, I don't even care anymore.

[@rey6708]

[@steele1485]

I still don't understand temp shift plates

[@DarkD112]

@@steele1485 Let's say you have a super hot aqua tuner. You put a temp shift plate behind it, that heat will spread to the surfaces around it a lot better than it did before. Even insulated tiles will start heating up if you have a temp-shift plate next to it. You can use temp shift plates, an aqua tuner and a steam turbine all sealed in a thermally insulated block to create a liquid cooler that deletes heat fast. And remember to create a vacuum first. Other gases like Oxygen will screw with the mechanisms. Use a gas pump and a liquid lock to create an easy vacuum. Ideal liquid lock will use something like Crude oil which has a high boiling point. Liquid locks use the fact that liquid sticks to the ceiling after a certain height creating a door dupes can walk through without breaking a vacuum.

[@steele1485]

@@DarkD112 I thought temp shift plates take in the temperatures of the tiles around it and even them out. And I guess my issue was not vacuuming my steam turbine room. Or a bad seed, I had a hot steam vent and a iron volcano within 10 tiles of each other.

[@DarkD112]

@@steele1485 Anything complicated needs a vacuum. Things like "hydrogen always goes to the top" is too absolute in ONI. Everything just ends up settling. Evening out the temperatures wouldn't be wrong either. But its practical use is better thought of as heat transfer. Like a hydrogen volcano typically makes gas at 500 degrees. If you try and use a steel gas pump on that, the pump will break. So you create a heat sink with radiant gas pipes and temp shift plates to pull the heat out of the gas and into a water boiler steam turbine.

[@dsch772]

About aquatuners, I think the better way to put it is: since an aquatuner reduces the liquid temperature by a fixed 14C, using a liquid with higher SHC means more thermal energy is being moved (from the liquid to the environment) with the same amount of power consumption.

Your oxygen cooling system is amazing! I usually use a thermo nullifier which is ok, but obtain power from it is just awesome.

[@SpottedHares]

One of the exotic, but also very simple early game ideas, is the heat battery. The interesting thing about the heat battery is that it can use what ever you want, liquids gasses or even solids. The idea is presented in the video but always as a component of more advanced systems. The real advantage of the heat battery is its ability to begin storing and containing heat before the player gets to the point of having the more complex systems of any reason. They also have the advantage of being able to easily be converted into more complex and effective systems with out having to completly destroy the original structure.

[@martinbennett9908]

Here's a tip after learning from my mistakes - be careful where you route your automation wires, in my steam turbine cooling system I failed to notice that an automation wire went through the port of the liquid vent, so when the aquatuner stopped the vent closed and the water in the pipes turned into steam and broke the pipe. Had to seal off the area to fix it up, mistake learned :)

[@probablynotmyname8521]

An important thing to know about crops is that they have a “body” temperature, basically the temp of the plant itself. So the surrounding area or gas may be at the right temp but the plant still wont grow because its body temp is too high/low. This is most important when using irrigation tiles.

[@FrancisJohnYT]

Don't change the temp of the hydroponic tiles, change the temp of the gas the plant is in.

So you could connect the battery automation wire to the transformer instead, and delete the cutoff, the bleedoff from the transformer would be minimal. Though it wouldn't actually be electrically better then the cutoff.

Well that simplify's things, will have to make a correction to this on the next temp management video.

[@Shabazza84]

Newbie here again. Btw, my first ever colony is now in cycle 260 and still going - partly thanks to you. ^^ Question for the setup near 10:30: I see this in 2 versions on KZbin. Yours, where the pipe from the Aquatuner is solely routed through the steam turbine chamber, to cool that H2 or O2 in there. And the thermal load is piped through the vapor chamber to cool the load. The second variant I see, is, where the pipe from the Tuner gets piped through the steram turbine chamber and then further through the thermal load. (So not going through the vapor chamber. Basically your "Cold box" setup. But with just a normal thermal load and no explicit cold box.) I guess, when you have to cool a super high temperature machine like the Metal Refinery, leading the pipe with pre-cooled liquid through the vapor chamber will still be cold enough to effectively cool the Metal Refinery. But when you want to cool something

[@FrancisJohnYT]

Not sure I understand the question but let me try and explain. 10:30 is for cooling high temprature, ignore the aquatuner for a second. The heat output from the metal refinery is so high >125C it causes the water to boil to steam which is then converted into electricity. You are effectively turning waste heat into free energy that you can use to help run the metal refinery if you wish. The Aquatuners only purpose in this build is to keep the steam turbine from overheating. You could rip out the aquatuner and cool the steam turbine another way like Wheeze, Ice plates or a thermoregulator. The Aquatuner is just the most efficient way. 15:30 this version is for cooling down things to below 120C, cool your O2, crop area, temprature control sleet wheat. If you tried to cool down your metal refinery output with this it would cost you a fortune in power. Go to the metal refinery and hover over the different recipes, it tells you how much heat it will dump into the coolant liquid and how much that will raise the temp of the liquid. The metal refinery is special, it dumps enormous amounts of heat into it's coolant. While you could feed it water and then cool that water brute force style with an aquatuner why not fed it a high temp liquid like oil, let the oil get above 125C, use the hot oil to power a steam turbine and get free power instead.

[@AvNotasian]

The heat problems... I didn't know it could be destroyed and I was playing in a version where there was no space so the only solution I came up with was a vacuum isolated steam room to store all those joules... And then I ran out of water, and then dirt. The game has gotten much easier since then.

[@vulkandrache1928]

Fun fact ( i havent checked the math but it sounds correct): The electrolyzer destroys heat if fed with water above 20°C because of the difference in heat capacity between water and the gas.

[@FrancisJohnYT]

Can be done. Usually not for temp destruction purposes but usually because 95C water is all you have on hand.

[@FerrybigGaming]

Another way to cool down steam turbines is to use the 95 C water it gives. It provides enough cooling for 125-130 C steam (steam turbine red-orange)3-4 steam turbines with this self cooling offset the heat produced by a metal refinary, and this is how I have an power positive metal refinery in my base.

[@FrancisJohnYT]

I'm using that technique to cool metal volcano's, it's really handy to cut down on the infrastructure investment.

[@WalkerRileyMC]

I just used a smooth hatch farm to produce my refined metal for mid game entry. 10 smooth hatches early enough will produce more refined metal over time than you'll need for the entire midgame.

[@AKUJIVALDO]

True-ish. However smoothies will eat 25% metal ore and give you some meat in return. I use only 5 of them(with 1 unpowered incubator) per stable. Way less heat. I'm not in a rush. I simply drown vents, geysers and volcanoes with water and then research them without needing a atmo suit. MR+AQT+ST will make your mid game way easier. And of course it is only way to make steel in long run and big quantities.

[@Lorens4444]

One of the ways to deal with heat that I found quite useful is dumping heat into fuel and then consuming the fuel. For example, dump heat from Metal Refinery into Petroleum, then send it into Liquid Reservoirs that your Petroleum Generator is consuming Petroleum from to power said Metal Refinery. Heat is deleted, and everyone is happy. You might say that it's inefficient because you didn't turn that heat into power, but you also have to consider how labor intensive and time consuming is the construction of the cooling loop and how much do you actually need that power.

[@atheistyoda8915]

True, but a cooling loop that's been setup will be much more reliable and easier to manage.

[@krzosu]

The problem is getting to the steam turbines in the first place and early on the best you can do is with gold amalgam (which i highly recomend getting early on as +50 max overheat temp is VERY usefull on all machines) - so at least in my case (i'm a noob though :P) ive created a box (sorta large - for large capacity if needed) - that box was insulated with igneous rock insulation tiles -inside there was an aqua tuner (or you can go with gas as coolant as well) there was also a liquid vent that could pour water directly at the tuner - to keep if from the overheating. (you should keep a lot of liquid in there as heat buffer) since it will evaporate - later on you can automatise the process to make sure there is someliquid via automation. via sensors - so you dont have to keep an eye on it yourself every few moments. The idea is that you use the refinery - the heat gets dumped into aqua tuner - which boils the water in the box- thus making steam - and keeping the heat and steam inside the box for later use when you can make some plastics to make the turbines later on. This is very easy to manage and it can solve a lot of early issues with heat :) So in essence it allows you to deal with heat early on - all the while making it usable later on for the turbines :)

This is exactly what I was looking for, as I just started converted my masses of various heat-generating machines into an industrial brick, so thanks! One question... I've noticed that even though the room is full of steam, with CO2 at the bottom (from the petroleum generators), I still see the occasional blob of polluted oxygen floating around near the top. I suspect it's from the polluted water being generated by the natural gas and petroleum generators. Even though I have a liquid pump at the bottom pumping that out, I guess it's offgassing and producing blobs of polluted oxygen that float to the top. Will those impede the steam turbine in any way? Does it only ingest steam, and will leave non-steam blobs of gas there? Or will it suck them in but then jam up and stop working (like when the wrong liquid is fed into some machines)? Thanks again!

[@FrancisJohnYT]

I think it will bock the turbines, you should only get polluted O2 forming if the pressure in the room is below 2kg. I keep my room at +15kg and no O2 can from from the polluted water.

I usually find it easier to get early steel than early plastic, and so having some more good designs for turbine-less setups would be great. Personally I found it worked great to pipe 10% packet throttled ethanol though my hot room to be directly burnt by my petroleum generator, to burn 300C ethanol. One downside of this is that some ethanol vapor appears when it is burnt, so you need to properly separate it from the polluted water in the output pool.

Is there a kind of rule of thumb for how big an ice box ought to be? I am referring to your earlier video on rockets (part 1) in relation to creating liquid O2 and H2, and not wanting too much liquid O2 in the liquid O2 tank, and that a bigger liquid H2 tank if higher liquid H2 production rate is desired (these two tanks are essentially the icebox, right?). Also I have a similar industrial brick set up in my base but my ice box (stole your design up there with a pump and vent setup, instead of a constant loop) somehow stabilises at around 60C, still trying to figure out why (though it's not really causing any critical failure), but I doubt it has anything to do with its size (though my icebox is slightly bigger I think sizing at 3x3).

[@FrancisJohnYT]

Unless your industrial brick is producing a megaton of heat you should be able to reduce the temp of it as low as your coolant will allow. Double check your insulated/radiant pipe and make sure your not exchanging heat where you should not. Also double check your temp shift plates, remember they can exchange heat diagonally not just left/right up/down. For the Liquid O2 H2 tanks I tried to make them small as it generally a waste to have more than 5/10 tonns on hand at any one point. If you check the rocket calculator you can figure out how much you would need if all your rockets requested fuel at the same time and plan accordingly.

Can you tell me the optimal pressure for the steam rooms under each steam turbine? I can't find any good math on why people use the amount of steam they use. I see you have gone with roughly 15kg per tile. I would love to know why

[@FrancisJohnYT]

Their is no real optimum. But I will mention that you want enough liquid that it prevents massive temperature fluctuations. Having way more than you need is fine so I usually put 200kg of water (one bottle empty) in each one.

[@grumpus88]

I think I overestimated how much cooling one of the aquatuner/steam turbine setup can provide. I was running 3 metal refineries, a power grid cooling pipe, and my main base cooling pipes, and all of my oxygen through it. It couldn't keep up and now my base is getting too hot. Had to shut down the refineries. Also made another for cooling petroleum and oil that I pulled up from the oil biome. It was coming in at about 250c. It was cooling it fine until it caused the polluted water it runs through to evaporate. Now I have a big mess on my hands :\

[@charlesbrocchiero2307]

I personnaly just rush isolation in early game. I wrap my "living quarters" and farms with isolation and keep everything that produces too much heat outside.

[@FrancisJohnYT]

That is a pretty big investment of time and effort, I prefer to be fast and flexible at the start. Then once you have the tech and resources heat is a non issue.

[@acheron16]

[@greedtheron8362]

This is one of those nuggets big enough you can't flush, lol. Also should mention that Thermium is technically better than steel for Thermal Conductivity, but you'd need such a huge temperature difference to really notice the benefit. Also, I really wanna see someone actually make a 'vent to space' cooling system instead of just saying it's technically possible, even if only for the bragging rights.

[@FrancisJohnYT]

The problem with vent to space is you could just take that heat and dump it into a steam turbine and make energy. That is why no one uses them anymore.

[@greedtheron8362]

Think of the bragging rights. But more seriously, what is the temperature of the CO2 coming out of your industrial sauna at when it gets into space? Might be worth it to run just one more Steam Turbine if that's how you're dealing with the heat.

[@seedlesswatermelon566]

I'm totally cool (no pun intended) with the aquatuner and steam turbine combo, the problem is, i never am able to get the power necessary to keep the aquatuner running. Usually I hook up a natural gas generator to it and get the rest of the power from the steam turbine itself. This only works for like 2 aquatuners at most though and I can't use coal since I don't ranch hatches. I don't ranch them because I don't want to run out of raw minerals. I don't like to just dig the whole map as that would expose my base to a whole whirlwind of temperatures that I don't want. tl;dr I can use this combo but i can't find power for it due to my fear of running out of resources.

[@FrancisJohnYT]

The first step is up to you. Demolishing the map is the one constant in this game for me. If you want to conserve the map you can but then you should go for the oil biome, that will give you access to the necessary power to get as much cooling as you need up. Though I should point out that you can get by for everything bar space with just one aquatuner if you want.

Great vid. It gonna make my future base more efficient. I have 1 more question. How Tempshift Plates actualy work and what's the point of using them?

[@francoiscoupal7057]

They act as lubricant to move heat around as a background prop. Normally it takes a long while for materials to transfert heat (between gases and tiles, or even between tiles without limiting dupes movement). And some gases and materials have a low thermal conductivity. The tempshift plate acts like a conduit for all nine "space" around it. They have a lot of mass (800kg, compared to a tile with 200kg, to a tile full of liquid 1000kg, to a tile of gases (between 1 and 20 kg for extremely high pressure; normal gas pressure for a dupe is 2kg to avoid the "pop eardrums" debuff)) and act like radiant piping for all their 8 other "space" arounf them, equalizing temperature between them at a quicker pace.

[@GamingStepByStep]

my biggest issue so far has been trying to get all achievements in one go since I stopped playing before they got added. So I went to oasisse and ran out of water, but I got a water geyser which is now supplying 80 C oxygen into my base lol so I guess it's time for an aquatuner setup

[@beefer23]

This is such a good guide but I’m just not smart enough to understand some of it! Is it better to use petrol or polluted water to cool refineries?

[@MoonLiteNite]

@17:23 my setup is close to this, but the metal tiles are not transfering the cold across the metal tiles and door. I used iron for my metal tiles and steel for door. Yeah 25% less thermal conductivity, but not 0. For some reason my cold transfer from my cold tank to my little icebox is soooo slow 5 cycles and have gone down like 5c :( Do i really have to use alluminium?

[@FrancisJohnYT]

Did you use any Temp shift plates? The water itself is not a great conductor, so the temp shift plates force the temp from the water/ice into the iron tiles.

[@fastfiddler1625]

This game is so damn cool. I wish there were more like it. My wife is kinda interested because she thinks it's like fallout shelter... Sure, honey.

[@lammaerb7867]

The turbine + refinery combination at 6 minutes doesn't seems to work for me - the turbine quickly overheats at 100 celsius, then stops working. Was there any change on that in the game since the video was made? Looks like aquatuner is a must...

[@0x0404]

I feel like it is a bit of a failure of game design that all our cooling solutions boil down to using a steam turbine setup. We have many many ways of doing pretty much everything else but cooling stuff off without throwing the hot product away leads back to the steam turbine.

[@FrancisJohnYT]

You have other option it's just...... if something is hotter than 125C you can get energy out of it from a steam turbine. At that point you lose the incentive to dump heat into petroleum and burn it off in a petroleum generator.

[@maxbrunner]

I tried to build the model with the two pools of polluted water, with the steel door in the middle to control the temperature flow between both sides. The aquatuner/steam turbine/right-hand pool are working fine, but there's no heat being transferred to the pool on the left side. The aluminum tiles at the right side of the steel door are at zero degrees and the left side ones remain at 30+ degrees, with no heat exchange between. The door is obviously open. Any idea of what could be happening?

[@FrancisJohnYT]

The door needs to close to allow temperature to transfer across. Use a temp sensor to regulate when the door opens and closes.

[@maxbrunner]

Thanks John! Your videos are awesome!!

[@chardonnay5767]

I'm a beginning player looking to move into the middle game. I made a chlorine-based germy water purifier and now am looking to tackle cooling somehow. From my perspective these guides are informative, but I struggle with actually building them. Would someone building these normally in game have a lot of gas vents and liquid vents left over inside the little boxes, or do you fill the liquid from the top and then build it once it's complete? From the guides I've seen on youtube, everyone just seems to use the debug mode and not play the game normally. And yes, I understand that the constructs in this video were probably built without the debug mode activated, but that's still not shown on camera so it's not very helpful for me.

[@blazingfish8486]

This comment a bit old, but check out his tutorial on industrial brick

[@TheIardis]

For me these designs seem not to be working? The heat exchange is *way* too slow. I have copied one of your designs from the video 1to1 (same materials, sizes etc) and it took half an hour to even warm the water enough to make it into steam? Am I messing up something or was there some patch or other?

[@FrancisJohnYT]

It depends on what you are trying to cool. If it's running flat out cooling something it's adding 14C to 10kg of water every second. If you only have 100kg of water in the steam room it would only take 71 seconds to get it to start boiling. If the steam room has 1000kg then it's ten times longer. Thiers a lot of variables here so I can't know what's off with your setup. I suppose the question is not is their steam but are you getting the cooling you are try to achieve? If you are then who cares if the steam room is not hot enough yet?

[@torinopeek]

I have an steam cool vent. Looking for some water (because i have 0 water / polluted water geyser, i literally have 4 cool steam vents), and looking for how to cool it down to a nice 20 degress. I tried this, at the start it was giving me 15degress water, but the sistem started to heat it up, 1 steam turbine is not enought. So by just making this sistem double (making it mirroring the first one), its just a joke how cool the water comes, i have to be careful or the water will freeze. This design is really good, thanks dude.

[@rehatas6059]

Man I couldnt find an oil biome in the map but can provide plastic thanks to dreckos. Will it work if I melt the plastic turning it into naphtha and use it as coolant? Is there an alternative coolant which is easier to acquire? (I also have got no tree)

[@Omni0404]

Hell yeah, turning problems into assets!

[@matthewjames2846]

Is there a tutorial that ebtter explains the filling of the loops with the liquid bridges? My liquid does not continue to cycle around then the aquatuner is off

[@waylandsmith]

Might you have had both a bridge and a pipe between it attached to your loop? Whenever you fill a loop, it's always important that all sections of pipe must have a reliably simple direction it flows in. The best way to control the direction of fluid when branching or merging is bridges. If you use a reservoir with a simple loop (no branches) the reservoir has a set direction and acts exactly like a bridge. And any time you're adding liquid into a loop, or really branching two pipes of fluid it's best to only touch the two routes via a bridge between the them. As an added bonus, removing a bridge never leaks the fluid, as it doesn't have any storage capacity.

[@MrEMaan]

For steam turbine, if on Terra and no access to aluminum (or more exotic materials), the radiant liquid pipe should be made from gold or copper (therm conductivity 120 vs aluminum 410)? Likewise, for metal plates (gold or copper has conductivity 60 vs aluminum 205). How much does this limit the cooling effectiveness or power efficiency of the steam turbine setup? Are there any design changes required?

[@MrEMaan]

Along similar lines: Is there an acceptable alternative to all the ceramic insulated liquid pipe? That is a lot of ceramic/kiln use for when I am trying to limit heat production. [400kg per pipe section x 20 segments = 8000kg ceramic, just for the refinery setup] I tried to use granite because I have a ton of it but the pipe broke from the heat. Would igneous work better or is ceramic the only alternative? I'm not sure which property to look at.

[@mdoerneman]

How you use ice machines is awesome! I got super frustrated cause the game doesn't TELL YOU THIS. lol I was like... it doesn't do ANYTHING! rage quit

[@AKUJIVALDO]

If you want game hold your hand play COD... The more you play ONI the more you learn.

[@sylentline7771]

do we need to pre cool the area before making ice box. industrial brick and power brick?

[@FrancisJohnYT]

No need to do that, once the cooling starts it should overpower any ambient temp. Well so long as you don't build it in magma of course :)

[@zhangdan5290]

This is the second time I've watched this video and one thing still didn't check for me, could you please explain why the central loop is doing the cooling while it is not exchanging temperature with the ice box...?

[@FrancisJohnYT]

It should be exchanging temp with the ice box. The Ice box is surrounded in metal tiles and radiant pipes run through it. As the liquid passes around the edge of the ice box in the radiant pipes it exchanges temp.

[@Soul-Burn]

In my base I use 3 steam turbines + aquatuner for a single refinery, with a largish 4x15 boiler room to radiate it, using crude oil (and some naphta I had) and the coolant still overheated to sour gas. In your example, a single turbine is enough to smelt steel without boiling the coolant. That said, I use an average of 2-3kg steam per tile, while you seem to use ~20kg. Is that such a big difference? Thanks again for your videos, keep up the good work!

[@FrancisJohnYT]

The extra mass makes a huge difference. Imaging a 500C 10kg bubble of hot liquid passing through a room that has a half a kilo of gas pressure at 0 C. With perfect temperature transfer the half kilo of gas and the 10kg bubble will end up at 476C. Now make that half kilo of gas 20kg and everything will even out at 166C. If you want to cool or heat things up having an awful lot of mass around at the temperature your aiming for makes for a very stable system.

[@Soul-Burn]

That totally makes sense. Moreover, due to TH clamping, low masses might not conduct too well. I think also the naptha was problematic. I thought it might be good because of the higher vaporization point and higher SHC, but its TC is *much* lower, meaning it sheds the heat slower. Made some adjustments that work better now. P.S. When cooling a cool steam vent, isn't it better to put the AT/ST in the room with the vent? That way you can utilize the fact it starts at 110, heat (with the AT) and get better cooling. In my system, I have a pool below the vent with doors that open when the pressure in the main room is too high. The AT cools that pool.

[@Doctorgeo7]

As a nerd, all these numbers and physics are making me giddy.

[@AKUJIVALDO]

Did you cleaned afterwards whatever device you watched this on? LOL

[@jsephhd]

sorry could you explain why an ice box is necessary. Like why can't you pipe directly from the aquatuner, or would a liquid reservoir do the same job?

[@ollikirsi9561]

*im pretty sure this is nerfed now somehow. I built this setup (Thanks mr.Francis) but I get nowhere as much cooling as in this video. Oxygen comes at 50 degrees and I get damage to liquid pipe because polluted water freezes. Input oxygen is 70c.

[@FrancisJohnYT]

The save game file is linked in the description if you want to open it up and have a look. As far as I'm aware it still works. Do you have a sensor to stop the liquid chilling below it's freezing point?

[@ollikirsi9561]

@@FrancisJohnYT I actually made a mistake with materials I was using. However even after fixing my mistakes I still had problems - it was very near the freezing point. At this moment I realized that I'm an engineer and I'm suppost to use my own brain cells as well. Therefore I removed the gate and metal tiles completely. Then I pulled the radiant cooling pipe to cross on top of the gas pipes. I set my coolant at 20 degrees and oxygen comes out at nearly the same. No more freezing problems I have noticed that Mr.John likes these gates in other builds as well and I assume they are very much needed at dealing with magma etc. Thank you so much for these old? but gold videos!

[@scaltra6709]

I'm confused, doesn't aluminum have the second highest conductivity only beat by thermium? Not steal? That what I got when I checked the wiki and the database but maybe ive missed something

[@FrancisJohnYT]

We talking about liquid or gas pipes? This is a weird one. Radiant gas pipes are made out of metal ORE, but radiant liquid pipes are made out of refined metal. So gold radiant liquid pipes have great thermal conductivity, however gold amalgam radiant gas pipes have the worst thermal conductivity. To complicate things further Radiant gas pipes can also be made from steel and space metal. So to answer what I think the question is, Aluminum ore has worse thermal conductivity than steel.

[@scaltra6709]

EDIT: now I know it’s not being deleted, per se, it’s being converted into electricity. Leaving this here in case anyone else needs it. So I’m FAIRLY certain I understand, but you skim over it so quick with repeated “all you really need to know is ____”s, and I’m very detail minded. For clarification, the aqua tuner moves heat into the steam, the steam powers and heats the turbine, and the steam turbine somehow then deletes heat? How is the turbine deleting the heat? Where is that energy going? How does the whole machine system you have not spiral into overheating as you pump more heat into it from the refinery?

[@boudewijnroell8846]

When I could the cooler the cold doesn`t seem to penetrate the automatic door with the 2 steel tiles left and right. Is that new or did I make a mistake?

The temp only transfers when the door is closed.

[@neavle]

I'm having this problem as well. I switched to using gold metal tiles (60 thermal conductivity vs 54 for steel) and I'm still not getting enough cooling from the center icebox to the side ice box. I have diamond shift plates in the side ice box, and iron shift plates in the center ice box. I'm going to switch to a design Francis shows in this video at 20:05: kzbin.info/www/bejne/aHLUZJ6Iid2fjZI, it seems like it would suck heat out of pipes more efficiently than the tiles + doors allow the side iceboxes to do.

[@clownical9783]

im having an issue where the output pipe of the aquatuner breaks because its too cold. how do i fix this

[@FrancisJohnYT]

You can't let the liquid passing through the aquatuner freeze or it will break the pipe when it tries to exit the aquatuner. You have to put a pipe sensor before the liquid enters the pipe and turn off the aquatuner if the liquid that is about to enter it is to cold. The aquatuner reduces the temp of liquids passing through it by 14C. The save game file is attached, you can download it and have a look.

[@S_Black]

I'm having trouble getting the aquatuners off the ground. I fully understand what I need to do. But on YT it seems like the boil almost immediately (though I guess the tutorials are usually sped up). But I do the same and the temperature changes only VERY slowly. So the cold stuff is only getting cold after a huge time and the steam has issues boiling. Or it's boiling, but then not reaching the next threshold for the turbine to kick in. I got a prototype now that's cooling alright (just a cool steam vent + some cooling loops), but doesn't produce power. The steam sits *just* under 125 and refuses to go over most of the time. Is this normal when you don't dump that much heat into the system? EDIT: Ok, so some diamond temp shift plates in the steam room help a lot. Granite doesn't work as well. Apparently the aquatuner isn't spreading around the heat properly. But I shouldn't really have to use a high end material like diamond for such simple thing

[@FrancisJohnYT]

This game usually takes a bit of things not working, followed by a moment of ahhhh that's how that works. Sounds to me like you figured it out in the end, for me personally half the fun is in the figuring out. The other half is figuring out how it fits into the rest of the game.

[@tuftyindigo]

Could you be adding too much water? The more water, the longer it takes to heat up. This example only had about 100 kg per tile, but you can fit ten times that much (and it'll take ten times longer to start up).
