Mechanized airlocks and thermal conductivity

[petkaretka]

Hey!

I used to think that opened mechinized arilocks do not conduct heat, but it seems they actually do, as they still exchange heat with radiant pipes run through them in a vacuum. If they are closed conductivity still seems much higher though.

Given a wiki page on thermal conductivity
https://oxygennotincluded.gamepedia.com/Thermal_Conductivity
I cannot understand why. There is no building to building heat transition in a list. Only building to tile (tile in this case should be vacuum, I guess?)

Are there any other ways to automatically enable\disable heat transition that actually work?

EDIT:

So bad I can't ad a screehshot! But my layout is this

I I I I
I D D M
I D D M
I I I M

I - insulated tile from ceramic
D - mechanized airlock
M - metal tile.

My raidiant pipe runs I D D D D I. I expect it to not exchange heat with anything, but it loses temperature on all D tiles even when they are opened. I want to use this build to heat up my farm when it gets too cold. And I can't figure out the source of heat loss. Could that be automation wire for doors? But it actually still seems to me that it exhcanges heat with open doors themselves.

What makes you think pipes and wires are buildings?

use insulated pipes if you want to minimize heat exchange with the door.

It shouldn't exchange at all in a vacuum except when they are closed. The only thing I can think of is that there is a little bit of gas at the doors. Was setting up a geothermal plant down at the core and a little bit of sour gas managed to get in between the window-door sandwich before I had a chance to seal it up. But I couldn't highlight the gas pockets in normal viewing mode. Instead I had to use the oxygen overlay to be able to select and see (with mod) the minute gas. Pipes and wires can conduct heat along the line, but that is so negligible as to be a rounding error. They are more likely to conduct heat with some element near by, i.e. something in the pipes or around it. The last thing I can think of is that it might be leftover heat from the materials used in construction. 400g of 100 C ceramic will still hold on to that heat during travel and have most of it when constructed.

Radiate Heat in Space is mod that allows heat to be dissipated so long as the equipment is in space. Specifically, I think it works by checking that the equipment is in the void element. Not vacuum, but void. So do you have a mod on that changes how heat exchange works?

[Strygald]

Even a tiny amount of gas would exchange temperature.

I don't have any heat mods.

I'd need to see a screenshot of your layout to see what's going on.

it's just the pipes heating. thermal transfer through conduction is still possible in a vacuum and since there's no air there's nowhere to dissipate that heat so it'll just continue to heat up until it reaches the temp of w.e it's touching/carrying

No, it is not, because in this game heat simulation doesn't consider buildings to touch each other. Doors are a bit of exception because when closed are treated by game engine as 2 tiles of solids.

So either OP doesn't have there vacuum or makes some other mistske. Also doors will keep transferring heat with pipes untill are fully opened and opening animation finishes.

pretty sure that's not totally true, though it's not as big of a thing in the game...

there's still the gas going through the pipe and if it's a bridge it will definitely transfer heat across it.

Well, then show example where 2 buildings in vacuum will transfer heat to each other.

tempshift plates do that specifically; and platforms in space seem to transfer heat to adjacent tiles that have no debris on them.

unless something changed everything transfers heat to everything it contacts depending on mass, conductivity, and the difference in temps.

edit: some things however seem to be specifically programmed to be exceptions; for example last game I was able to cool mechanized airlocks that my telescope was sitting on and the debris that were also sitting on the airlock with a cooling loop but it didn't seem to have and effect on the telescope it's self.

Thempshift plates don't transfer heat in vacuum to each other. Only to tiles and since it is a 3x3 building you will see it working between 2 tiles, but this is just another exception from the rule I mentioned.

Nothing changed, buildings in general never transfered heat to another buildings. Only tiles do and it work as medium for buildings. That is why in vacuum no heat exchange is possible. Obviously you have very little knowldege in that area.

Exceptions I mentioned already - doors and thempshift plates. Building don't exchange heat with solid tiles it sits on or touches from the side or above. Building must overlap with a tile to exchange heat with it.

This is why cooling robo miners in space is a pain. They don't transfer heat with the tile they're attached to, which itself can be cooled with radiant piping. They need a liquid or gas overlapping them to transfer the heat.

Read again what I wrote about the plates and how you can see them transfer heat in vacuum. The exceptions regard building transferring heat via touching other things.

If you still don't get then don't bother replying and wasting my time.

where did you ever mention tempshift plates? stop contradicting yourself.

[Hedning]

It's very simple. Tempshift plates connect to all 9 tiles because that's their purpose, while buildings in general only connect to tiles they occupy.

Maybe when I wrote: "Thempshift plates don't transfer heat in vacuum to each other. Only to tiles and since it is a 3x3 building you will see it working between 2 tiles, but this is just another exception from the rule I mentioned."

Are you r*tarded or just a troll?
