Freezer Insulation Idea, Thoughts On This?

[MythN7]

So its hard to double wall where the coolers are.

Do you think using vents with stone blocks like this could act like the double wall around them?

or would it just be like the vents are not there.

It would cut efficiency pretty hard. Wouldn't recomend it

On the one hand, the vents will act like an air space, and air is a great insulator.

On the other hand, vents transfer heat fairly slowly. So they might slow down the cooling system as it tries to transfer heat out of the freezer.

The best insulation for that freezer would be to build your colony around it, on all sides except for the heat exhaust. I noticed from the screenshot that the outside temp is 28 degrees. If the freezer was an interior room, it would be surrounded by rooms at 21 degrees.

The fridge in my base is towards the middle of it, with rooms on all sides. One wall of the fridge is adjacent to a small (six squares total) unroofed section that acts kind of like a chimney. The air conditioners exhaust their heat into that, so the heat goes straight to the infinite heat-sink that is the outdoors, but there's minimal contact between that chimney and the wall of the fridge.

Then in wintertime, I put the roof on the chimney and open one wall of it into the living room, so the cooling system for the fridge helps keep the base warm at the same time.

What you are doing there is worse than simply cooling the freezer. Just build a simple room with coolers.

There's no need to double the wall where the coolers are. You don't need to double every wall tile, especially if it's just three coolers.

2 coolers would be sufficient for a freezer room of that size.
You appear to be on a temperate map, so you do not need double walls to insulate it when a single wall will be enough.
You can also place the electric oven in the freezer room. As long as the cook wears a parka, they won't be bothered by working in the cold.

Doublewalls are only important on superhot maps, like 70-100C temps. What you do in those cases is make a double wall freezer, then create an air gap, then create another double wall with more coolers. The temperature physics in the game are a bit wonky, normally that would be less efficient, but in RimWorld it's more efficient, allowing you to reach much cooler and more stable temps in the "inner fridge." On such maps you can also tap it into your normal base cooling keeping your colonists alive. Like here was a fairly early base I made a while ago on a 100c map:

On maps where it might hit 40-50c tops, double walls only save a very small amount of power, you don't have to spend that much time or thought into insulating them. The good thing about coolers is you don't have to worry much about making too many of them because they do coordinate to some extent and excess ones will stay at low power when not needed and kick on during temp spikes to more quickly chill the room again. So in my above screen I had 4 coolers in my inner freezer, only 2 of them were needed and running at high power, the other two were usually idle.

A double wall improves cooling by 10-15C, which is an equivalent of 1-2 extra coolers, depending on your setup.

Hmm. On a 20C map a single cooler can bring a 9x9 interior single-wall freezer down to -4C, a single cooler on a 9x9 interior double-wall freezer brings it down to -8C. It's not a big difference and in this case the double walls do nothing. As the temperature and freezer size increases there will be break points where an extra cooler is required for the single wall and not the double wall, but that extra cooler will be mostly idle. So the power difference is generally rather small. The resource cost difference is mostly a wash because you are spending resources on the extra layer of wall, compared to the resources of the cooler, 90 steel and 3 components, vs say 220 of whatever resource you are using on just a 9x9 interior freezer. You should always build at least 1-2 more freezers than needed to handle heatwaves anyway.

And for breakdowns. It's always nice to have redundancy. Even with the extra component cost, I find it's much more likely I hit a Component Shortage far after I've completed my freezer... which is a very bad time to have a critical freezer break down with no backup.

I always double-wall. I may make a temporary single-wall freezer, but it gets beefed up fairly quickly when I have enough materials. And, since I usually have more batteries than most, it's nice to have that extra wall there just in case of a Zzzt blowing out a piece. :)

I find Steel and especially components to be way rarer than any of the stone materials, so I prefer to double wall freezing rooms or even the whole base building, if I build a single building.
If it saves me one or even two coolers, I have no problem spending some hundred stone block materials to doublewall the building.

If I go with the "Village"-Type of Base, which I prefer to do because I find it somewhat nicer to look at, I only double-wall the building dealing with storing edibles and corpses, preparing them for dinner and thus the canteen.

Btw what does double-walling do? Does it only keep cold temperatures inside or also hot ones, so basically slowing down the temperature equalization between the outside and inside in general?

[Astasia]

Double wall freezers are usually always going to be of some benefit, so if you have the space and the stone you might as well double wall what you can eventually. My point was more that it's not a high priority and worrying about one or two tiles not being double insulated, like the coolers themselves, generally isn't worth the thought on most maps. I often build symmetrical bases where a single double wall room/structure just doesn't look right in the design, and so I just wont double wall it in that situation and it's fine.

Ya it's generic insulation that slows temperature transference from one side to another. So on really cold maps double walls also help keep your base heated to a comfortable temperature. That said something to consider is that the cold temps of your freezer will seep through a single wall and help cool any rooms attached to it, which might be worthwhile to you.

I can't get the idea of this...
Do you know there are double-wall coolers that don't act as wall?

I believe one of those two mods provide them

Kinda off the OP, but thought i would ask it here.

is it ok to have the hot tile of the cooler venting into the garden?

I usualy build my freezer wall beside the garden, so that one of the walls holding in the zone of the farm is protected from wild grazing.

But instead of having a 2nd wall of the cooler exposed to the outside, could i put this item in the wall facing the crops? this way its also harder to reach from attacks?

not sure how drastic that one or near by tiles get hit with heat.

[Preechr]

Heat spreads so quickly outside it might as well not matter at all.

Does the garden have a roof over it?

If not, then the garden is basically a gigantic heat sink, and everything is..........



.........wait for it............



........fine.

What.........? Why are you staring at me like that??

A single cooler cools the 9x9 by 34C if it has double walls, and by 27C if it has single walls. That's 7C difference.
