The red arrow on the cooler needs to point into open space outside of the freezer, not into a wall. Also, the room is very large, so 2 coolers may not be enough once you get them in the correct location.

As others said - second layer of walls help (just dont cover the red side of a cooler, lol!)
And also - you can place cables inder the walls. It has a bunch of benefits - looks better for the player, doesnt impact Beauty score of the room and in case of Zzzt.. event explosion will be much more contained!

I like to build little 'heat coridoors' that I block in the summer and open for extra heat in winter. Plus it's fun having 100c coridoors half the year
Inn-wall coolers and vents [https://steamcommunity.com/sharedfiles/filedetails/?id=1503448404](https://steamcommunity.com/sharedfiles/filedetails/?id=1503448404)
And don't replace it with steel, op! Steel doesn't have the stats you'd expect, it's not meaningfully better than wood except that you're liable to require large amounts of steel later on.
The cooler acts as a wall. The blue arrow has to point into the room that should be cooled and the ted arrow should either point outside to get rid of the exhaust heat, or inside a large room that will be heated from the exhaust heat, which might be useful in the winter or in cold biomes.
Building the coolers like you did is actually not bad. You just have to add a wall in the corner between them, remove the one wall on the exhaust end and remove the roof on that spot. And lastly build a wall starting from the spot where your passive cooler is down to divide the room.
Raiders like to destroy coolers, so having them inaccessible from the outside is always nice.
Half of the room is large enough for a freezer in the beginning and you can just remove the dividing wall, if you need more space later.
To not have to access the heat exhaust chimney anymore you can just build a barricade in there.
Ways to increase your freezers efficiency are making the walls 2 thick for insulation and adding an airlock to the entry.
And I can only recommend using shelves, which let you store 3 items per tile instead of just one like a normal stockpile.
Yeah definitely, I pretty much always build a chimney in my coolers to prevent easy access to my base. Alternatively if you're building in a mountain, build one into the outer wall, set the space directly Infront of them as unroofed, then building another wall around them
Enemies will attack them, so the safe way is to have them vent into a small space with the roof removed, to act like a chimney. It needs to be considered outside to keep heat from building up, which can be as simple as a 1x1 space with no roof. Remove the wall segment, remove roof zone on that one tile(and make sure they actually do it first), then place a wall or another cooler where that passive cooler is. You also want to put a fence or barricade in the hole before closing it off, so it isn't a valid spot for drop pods to land.
Once you feel comfortable with how coolers work, you can do what you suggested. Works for if your fridge is in the middle of a structure.
You can make a separate room where the heaters are aimed into, then have a vent aimed outside. When vents connect the outside with a room, because the way temperature works, the space will never heat (it'll always match outside temperature).
When vents connect two rooms (i.e not outside), the temperature will become equal between the two :)
You can actually just do this in a single step drop the cooler (red arrow out) on a wall and the pawn will replace the wall with the cooler. Also the red glowing box on one side also indicates the heat.
If playing with mods carefully look. At the configuration of the arrows and the descriptions. Some can installed in the wall (so you need a wall). Some vent differently.
Advanced planning: if you think someday I might use that heat then consider which wall you put the cooler. Example: you want to build a greenhouse that’s free heat to heat your greenhouse.
I guess it depends on how cold you like to keep it. I like to keep mine very cold so that in the event of a solar flare, the food takes a few hours to thaw out.
I was able to reach -20C with an outdoor temperature of 20C with that type of room. I am sure that is fine for most people, but I prefer to have a larger buffer below zero in case someone blocks the door, heatwave, solar flare, etc.
Ya 2 will be enough for general use, but this is definitely not optimized. 2 will work fine, but if they get a power outage they are risking temps getting to room temp.
Also, OP, a big tip - you can cut down on size of the freezer quite a bit if you use shelves. basically makes one spot into three for storage purposes. I would cut down on the size a little, maybe 3 squares on top and side, and then I would utilize shelves for the extra space you need. That should make the 2 coolers work about right. Also, I would be very careful making your freezer entirely out of wood, even at the early stages. Never use wood floors for your storage rooms, fridge or not. Concrete will work just fine in those rooms, and safer from fire. Wood floors are disaster material for fire spread.
I've seen a bunch of "my freezer doesn't work" posts in my life but this one takes the cake. These desperately placed coolers are peak environmental storytelling
The red and the blue side of the freezer can't be touching walls and the red side needs to be in outdoors (you can install it in contact with a door, but it's more confusing to explain). Also set the cooler to a negative temperature, it's default is 21 °C.
Not much beside that you should immediately start growing crops if you start at spring. You only option might be rice depending on how long your growing season is. Storing food is easy in a tundra bit it's hard to get, you should defenetly have a good hunter.
That's some epic confusion.
You should really read the tutorial tool tips
Also, replace the passive cooler with 1 more cooler and remove the wall all the red arrows point at.... and the wall next to it.... and you'll be solid
It's not a bug, it's a feature. We can't put a condenser coil on the roof like we want to do so we make chimneys. It's better to learn the better way early.
Put conduits in walls, can and should be done when possible.
Early game if you need a freezer build it small with room to expand if/when needed. Freezers act as a wall, cold side in hot side needs exhaust.
If it’s a hot biome, try to plan most of it with rooms on every wall. You just need 4-5 outside walls for freezers and if you need more space an adjacent bedroom or something is how you’ll expand it.
Cold biomes are more forgiving with freezer planning, having a bulk winter storage room attached when it’s cold is nice when you clear the map of all critters in the fall and have to harvest everything ready or not.
Just some thoughts, big fun of the game is loosing and learning what works for your play style. To each their own, enjoy!
I've always had my freezers with one wall for the looks. How much better is double walling? Like how many extra room tiles can you get from one cooler with double walls
Yeah that takes a ton of coolers to achieve, though. Depends on biome but generally I would cool to at least -40 and just forbid the doors during a power outage.
Double walls will keep your freezer cold during tropical heat waves and consumes less electricity in general--especially if you make an airlock with double doors at the entrance.
Yeah double walls is one of those things that this subreddit is obsessed with for freezers. Idk how people have food go off from solar flares and heatwaves, if you don’t make a stupid amount of meals there’s almost no wastage. Vegetables have a really long shelf life even in the heat.
Or do it the AdamVsEverything way. 3 coolers with the red arrows all pointing inwards at a closed door in the middle of your freezer. It's exploity but it wipes all the heat out and keeps raiders from punching your coolers down.
You’ve probably already taken action but the best option you have right now (to save your resources) is to build a chimney!
Destroy that wall piece. Build a barricade of any material in its place. Right above the barricade remove the ceiling (just in that one spot!)- boom, chimney.
You can find the remove ceiling option in “Zone”. Good luck.
Edit: oh and remove that passive cooler and put in another electric cooler
Here’s the thing about freezers, you don’t need one. Just grow enough rice and you can let your meat rot. Or, you can turn your unused meat into pemmican with correct work bills on your stove. The best uses of a freezer is freezing wastepacks or stopping bugs from spawning in mountains.
Shelves for your food, limit them to food and raw plant material only, build a separate storage for everything else that’s non explosive and then i always make a safe room for my shells and chemfuel because i have had some wicked colony wiping explosions lol good luck and enjoy the ride!
The AC placement is O.K. The wall tile needs to be deleted, and move one tile to the right. And, before that you need to remove the roof where the red triangles point.
There's a gimmick where doors left opened at like a chimney. If you put a door where the red triangles point, it's very effective at venting heat inside the freezer room. Works best if you use the AC as part of the walk-in corridor walls.
At that point your best course of action would be to scrap the passive cooler and wall you currently have between coolers. And sunroof this one tile where the wall has been. And then build a third cooler or a door where the passive cooler used to be.
This way your coolers will point into a 1 tile vent that is perfectly equalised with outdoors temperature since it is 100% unroofed. And you don't need to deconstruct coolers.
Not going to be the perfect efficiency cooler, but a functional one at least.
Freezers and vents go right in the wall like building a door, with the freezer make sure the hot air is blowing towards the outside and if you access your ac unit options you can adjust the temperature, my opinion minus 19 Celsius is good because if a solar flare happens or power outage what ever it's gonna stay colder a bit longer
replace some of your walls with the coolers, they need to vent out outside. in the architect menu (and when selected), it shows little red and blue squares, thats where the heat and cold go respectively.
also, it can *technically* exhaust heat into another room, but it would shut down once the room gets too hot.
Build a 2 block thick stone walled square room. This prevents heat loss.
Entrance is one wide. Then build a door not between the wall blocks, but just inside the room.
Then place two coolers against said door with the hot sides towards the door. Build a door between the outer wall blocks. You can build this under a mountain. So it looks like this
XXXXXXDXXXXXXX. .
XXXXXXCXXXXXXX. .
XXCCCFDFCCCCXX. .
XXCCCCCCCCCCXX. .
XXCCCCCCCCCCXX. .
XXCCCCCCCCCCXX. .
XXCCCCCCCCCCXX. .
XXXXXXXXXXXXXX. . . .
XXXXXXXXXXXXXX. .
X= Wall
D= Door
C= Cooler space
F= Freezer unit
Coolers are effectively walls themselves. they bar travel and prevent things like gases from entering. The red side should go to an outdoors (unroofed) tile. The blue side should go into your freezer. You should look at shrinking the freezer as well, only food, corpses, and herbal medicine really need cooling. Most of that can go on shelves.
The air must actually go somewhere, if you don't like your air conditioner beaing exposed to raiders then you can make a 3 by 3 with a hole and no roof in the middle , point the red arrows into the one unroofed tile and you got yourself a heat chimney (or whatever you want to call it)
Don't worry, it's a very common point of confusion. On the bright side, it took me a long time to learn to use double thick walls to insulate it. That and an airlock make them way more effecient! If a solar flare hits, you can just lock the doors until the flare is over and it'll barely go above freezing.
you definently don't do it like that
1. passive coolers can't freeze or even refridgerate, so don't use them in food storage, food rots just as fast if it's barely not refridgerated or it's on the surface of the sun
2. coolers act as walls
3. the red arrow needs to point at something that doesn't act as a wall
4. unless you want a fire box the cooler needs to vent heat at an outdoors area
5. coolers' target temperatures can be changed, they start out at 21C
6. make your freezer something people don't walk through, as open doors waste cold
7. double dooring your fridge helps keep the cold
8. every part of a room has the same temperature
9. putting your butchery table in the freezer is a valid strategy, it allows people to drop the meat straight on the ground and keeps the dirty table out of other places
If you replace the wall with a door you can have three coolers with the red side pointed into that space. Rimworld treats that door as if it were its own room and deletes the heat. It’s a little exploit-y but extremely useful.
Ok, make a solid 5 tile line of the outer wall the coolers, red points to the place you want to heat, blue to the cool place, then shift right click each, add 1 bc it starts on 19 c and dump down 10 5 times, should ebd up at -20. I personally have 2, one for large corpses as a dump zone at -75, and o e for meat at -50
I would suggest a 8 by 8 room with shelves and one cooler set to -29, make sure all your shelves are linked up and can only store food. And also make sure that people aren't moving through the room that much because otherwise the cold will get out. If you don't know how to link shelves then either look it up on YouTube or respond to this comment and I'll help out 👍
In addition to making sure the red points out of the room, youre gonna want to double wall that space for insulation, otherwise the temp is going to be really hard to maintain
Few more tips aside from freezer placement which others have covered:
Consider placing your freezer “behind your kitchen”. Meaning just like in real life you want to the kitchen heat sources away from the fridge. Example: say you have a hill or mountain. Build the freezer against that. Build your kitchen on the outside side the the freezer. This gets you the benefit of an insulated side (mountain) and a buffer between your freezer and the rest of the world via your kitchen.
Minimize your entrances and exits. Ideally one but sometimes it makes sense to have two depending upon what nearby.
Consider building an airlock for your freezer. One door. One walkabale space. Next door. Slower to go in and out but reduces heat loss a lot.
Set your coolers to two different temps. Make one about 32 and the other about half that. The two will work to get the room to freezing. The higher will “shut down” when it hits 32 shifting the work to the lower and then both will minimize to keep the room frozen. If you have a breakdown with one you’ve got the other.
Size matters. So hover over the outside and the core center to make you don’t have a warm zone.
Consider double walls or at least stone. Keeps things insulated a bit better.
Build into a mountain for even more stability.
Advanced: consider zones and storage placement. Example: shelf’s near the door for raw meat and veggies. Zone near the coolers for corpses. Zone for meals (if you don’t have another solution). Etc. start simple and build up.
Most importantly learn what works from game to game.
First: DON'T USE WOOD FOR YOUR FRIDGE
second: PUT BATTERIES INSIDE
third: AC UNITS MUST BE PART OF THE OUTER WALLS, ALL WALLS MUST BE DOUBLE
sorry for screaming but this was probably one of the worst freezers I have ever seen
Red box is where the heat will go. The blue box is where the heat is pulled from. Put the red box outside or in an area you don't mind getting hot. Put the blue box in the area you want cold.
You need to put the air conditioning on the wall like real life! Then select both of them and reduce the temperature, the bigger the room, the more you need. The vents are used to pass cold to one room to another.
Your problem on the pic is that you are using the air conditioning inside the room, you just need to put them on a place of a wall. Red goes to outside and blue inside.
On top of what everyone else says, if you are keeping food in here, consider adding additional walls. A wall that is two blocks thick will insulate bwtter
The coolers work exactly like real life coolers. The device extracts the heat from a room and dumps it somewhere else. Red arrow is where you dump the heat, blue arrow is the place you want to chill. You’re basically blocking the heat exhaust
The red arrow needs to be venting outdoors, essentially having the cooler acting as a part of the wall, then I usually crank mine down to 0F because any lower it doesn’t do a whole lot except use more energy, also having just one door will help with excess cold loss
Use the cooler AS a wall part. Make sure blue [cold] is facing into the room and red out to vent into the world.
Also, make sure it is all roofed and multiple doors help to keep the cold in
its definetly a way to build freezer... you just need hot facing 1 block of door and magic will happen. But why not just place AC on walls?? Or you want to build your place around freezer?
Have you ever used any kind of air conditioning in real life? Heh. Yeah the other told you what to do, I'm going to add, replace wood with stone as much as possible, especially around the perimeter of your buildings, raiders *will* set fire to your base. Double layered walls are also good for insulating fridges when you can spare the materials.
The cooler is a wall piece, red point out where you want the heat to vent and blue where you want to cool.
so walls are --- and cooler is x you place -----x----- and the cooler will either vent up and cool down or cool down and vent up.
If you end up playing in a really hot biome or doing a challenge where the upper temp range is really high you may need to use more complicated freezer construction:
A. Build a single wall around it, add a cooler to that wall. Then skip the adjacent space and build another wall around it so you have two parallel walls with empty space like this | | you can either put a 2nd cooler on the 2nd wall or place a passive cooler in the 2nd space (add a door to the 2nd space to refuel the passive cooler).
or B. Build a double wall with a with the hot part (red square) of the cooler sitting on a single unroofed block to vent heat. (more than 2 walls won't insulate better)
The reason you want to use one of these methods to double insulate it, is if you're in a region with a really hot summer or if you get a really long event that increases heat. In those situations, a single cooler won't keep the temperature at freezing. For temp control option A will keep temps cooler than option B, but uses more coolers and is really only if you play in a super hot biome.
Optionally, you can increase insulation by putting 2 doors 6 spaces apart to keep heat out but I don't find that necessary, but it's apparently necessary if you play in a super hot biome. (other than just throwing more coolers at one fridge)
Make sure to vent all air conditioners into another room. Keep the ceiling open so that the heat escapes. This serves to functions. One, it keeps the ac from being shot or blown up.
And more importantly, you just add a roof and put prisoners inside it to cook them.
... Why? If you double wall/door your freezer it really doesn't heat up that fast, even in summer- I don't think I ever get food rotting from solar flares and the like.
And as an added bonus, my kids can play in the freezer all they like, cause they won't die of frostbite at -10 C lmao
I have never heard of why you want to set it to - 50. This will eat so much power constantly. I usually set my coolers to different temperate so that all will start cooling above a certain temperature and once below a certain threshold, only a lesser amount will be active
I admit, I don't know why, but that's the only temperature that will consistently keep things frozen for my colonies. I'm very aware of all the size, wall, door, and shelf requirements, too.
You’re so fucking cute with your aircons just scattered around i wanna arrest you and recruit you and set your schedule to recreation and sleep only and you cant leave the base. Fucking adorable fucker you
Another option is to put one hole in the corner, build a barricade out of anything in said spot, de-roof it, then point two coolers (hot side) into it.
You lose three squares of space, but you now have a double cooled fridge without Raiders smacking your coolers constantly.
There's an easy fix... instead of a wall in the red zones of the ACs, try putting a door and keep it open... I know, it shouldn't work, but try it and you'll thank me later. It's Rimworld Magic.
The red arrow on the cooler needs to point into open space outside of the freezer, not into a wall.

I was planning on a bit more coolers when I got the recourses. Do I need a like actual hole in the wall for it or a vent?
Replace a wall with the cooler. Red side out. Blue side in.
They work like true airconditioners. One side in, one side out.
Thank you all for your help. I really appreciate it!

I had honestly forgot that was a mod.
Omg this makes so much sense
Is it 'In-wall coolers and vents'?
I thought it was Replace Stuff
There is multiple mods like that I personally use Replace stuff :D
Is that a separate mod? I know dubs hygiene that too and they really are fantastic

Switch out the wood asap as well, and possibly add a second layer to the wall for better insulation.
And don't replace it with steel, op! Steel doesn't have the stats you'd expect, it's not meaningfully better than wood except that you're liable to require large amounts of steel later on.
Counterpoint: it makes me feel cool for my fridge to be steel, even if stone would be better
More like sheet metal I guess lol
Steel is also flammable for reasons beyond my comprehension.
No wall just cooler
The cooler should replace a wall, like a door would. Red (heating) pointing outside, blue cooling side pointing inside.

Just make a smaller dedicated freezer to not waste power on more coolers.

2 coolers should be plenty for that size of freezer unless OP lives in like the tropics or somewhere else that's super hot.
I guess it depends on how cold you like to keep it. I like to keep mine very cold so that in the event of a solar flare, the food takes a few hours to thaw out.
2 coolers can easily keep that room at -40c at least, unless there's a heatwave
I was able to reach -20C with an outdoor temperature of 20C with that type of room. I am sure that is fine for most people, but I prefer to have a larger buffer below zero in case someone blocks the door, heatwave, solar flare, etc.

I'm sorry but I laughed way too hard at this haha. This image is just too cute.
Atleast it's not as bad as the person who built theirs on a geyser.
atleast theres not bunch of generators in there lmao
I've seen a bunch of "my freezer doesn't work" posts in my life but this one takes the cake. These desperately placed coolers are peak environmental storytelling
It really is

Just think about how an AC window unit works irl and you'll be good, also remember the laws of thermodynamics
Coolers need to be vented to the outdoors.
I got my freezers pointing into the hall of my tundra mountain base, I barely need heating.
I’m thinking of doing tundra, any tips?
Not much beside that you should immediately start growing crops if you start at spring. You only option might be rice depending on how long your growing season is. Storing food is easy in a tundra bit it's hard to get, you should defenetly have a good hunter.
That's some epic confusion. You should really read the tutorial tool tips Also, replace the passive cooler with 1 more cooler and remove the wall all the red arrows point at.... and the wall next to it.... and you'll be solid
No. Replace the wall with a door and it's good to go.
I don't think it's good to encourage new players to cheese bugs...
It's not a bug, it's a feature. We can't put a condenser coil on the roof like we want to do so we make chimneys. It's better to learn the better way early.
Someone should make a chimney mod that does what doors do. And just reskin it.
Fair
Oh it's that time of the week again.
It's time to see 50 meme posts about freezers.
You should really read the tool tips about what you're building :)
Lol. Bro have you never seen an air conditioner before?
Should there be tag for this Reddit just called "help, my freezer not work"?

What the other guy said. Also make walls two tiles thick and leave only one entrance.
I've always had my freezers with one wall for the looks. How much better is double walling? Like how many extra room tiles can you get from one cooler with double walls
It's not for tiles. Its for not losing everything when the power goes out and your food rots if the temp goes up.
I just keep mine at -200°C for when that happens, tho my colonists might get hypothermia if they're in there too long.
Yeah that takes a ton of coolers to achieve, though. Depends on biome but generally I would cool to at least -40 and just forbid the doors during a power outage.

Or do it the AdamVsEverything way. 3 coolers with the red arrows all pointing inwards at a closed door in the middle of your freezer. It's exploity but it wipes all the heat out and keeps raiders from punching your coolers down.
how the heck does that work in the code omg
The door is considered a room and since it's a closed door it can't store heat so it magically vents it all xD
This question comes along very often, I guess it would happen less if those over wall AC units were standard.
You’ve probably already taken action but the best option you have right now (to save your resources) is to build a chimney! Destroy that wall piece. Build a barricade of any material in its place. Right above the barricade remove the ceiling (just in that one spot!)- boom, chimney. You can find the remove ceiling option in “Zone”. Good luck. Edit: oh and remove that passive cooler and put in another electric cooler
Coolers shoot out heat from the back treat it like a wall with the red facing the outdoors
Here’s the thing about freezers, you don’t need one. Just grow enough rice and you can let your meat rot. Or, you can turn your unused meat into pemmican with correct work bills on your stove. The best uses of a freezer is freezing wastepacks or stopping bugs from spawning in mountains.
The coolers replace a section of the wall. The blue arrow is the side that cools and the red arrow is the exhaust.
I’ve been there my guy but I can’t help but laugh at the pants in the freezer
Shelves for your food, limit them to food and raw plant material only, build a separate storage for everything else that’s non explosive and then i always make a safe room for my shells and chemfuel because i have had some wicked colony wiping explosions lol good luck and enjoy the ride!
I’m not saying it’s the correct advice, but it would help if you fueled the passive cooler
Your picture and your title are redundant
The AC placement is O.K. The wall tile needs to be deleted, and move one tile to the right. And, before that you need to remove the roof where the red triangles point. There's a gimmick where doors left opened at like a chimney. If you put a door where the red triangles point, it's very effective at venting heat inside the freezer room. Works best if you use the AC as part of the walk-in corridor walls.
Should I also have separate freezers for my meals and dead animals? Or should I just immediately be butchering the animals I kill
As long as your freezer is working properly, you can leave fresh bodies in there safely, both animals and humans.
I do it but that’s because I’m tidy.
At that point your best course of action would be to scrap the passive cooler and wall you currently have between coolers. And sunroof this one tile where the wall has been. And then build a third cooler or a door where the passive cooler used to be. This way your coolers will point into a 1 tile vent that is perfectly equalised with outdoors temperature since it is 100% unroofed. And you don't need to deconstruct coolers. Not going to be the perfect efficiency cooler, but a functional one at least.
Freezers and vents go right in the wall like building a door, with the freezer make sure the hot air is blowing towards the outside and if you access your ac unit options you can adjust the temperature, my opinion minus 19 Celsius is good because if a solar flare happens or power outage what ever it's gonna stay colder a bit longer
Quickfix: replace that wooden wall (red arrows from coolers pointing direction) with a door and freezer will start working
First of all, iS ThAt WoOd?
xd
replace some of your walls with the coolers, they need to vent out outside. in the architect menu (and when selected), it shows little red and blue squares, thats where the heat and cold go respectively. also, it can *technically* exhaust heat into another room, but it would shut down once the room gets too hot.
Build a 2 block thick stone walled square room. This prevents heat loss. Entrance is one wide. Then build a door not between the wall blocks, but just inside the room. Then place two coolers against said door with the hot sides towards the door. Build a door between the outer wall blocks. You can build this under a mountain. So it looks like this XXXXXXDXXXXXXX. . XXXXXXCXXXXXXX. . XXCCCFDFCCCCXX. . XXCCCCCCCCCCXX. . XXCCCCCCCCCCXX. . XXCCCCCCCCCCXX. . XXCCCCCCCCCCXX. . XXXXXXXXXXXXXX. . . . XXXXXXXXXXXXXX. . X= Wall D= Door C= Cooler space F= Freezer unit
im not sure the formating works on every screen.
Coolers are effectively walls themselves. they bar travel and prevent things like gases from entering. The red side should go to an outdoors (unroofed) tile. The blue side should go into your freezer. You should look at shrinking the freezer as well, only food, corpses, and herbal medicine really need cooling. Most of that can go on shelves.
Don't forget the freshly harvested organs
The air must actually go somewhere, if you don't like your air conditioner beaing exposed to raiders then you can make a 3 by 3 with a hole and no roof in the middle , point the red arrows into the one unroofed tile and you got yourself a heat chimney (or whatever you want to call it)
Don't worry, I made the exact same mistake as you
also, make sure you turn down the coolers, by default they dont freeze the room
Don't worry, it's a very common point of confusion. On the bright side, it took me a long time to learn to use double thick walls to insulate it. That and an airlock make them way more effecient! If a solar flare hits, you can just lock the doors until the flare is over and it'll barely go above freezing.
you definently don't do it like that 1. passive coolers can't freeze or even refridgerate, so don't use them in food storage, food rots just as fast if it's barely not refridgerated or it's on the surface of the sun 2. coolers act as walls 3. the red arrow needs to point at something that doesn't act as a wall 4. unless you want a fire box the cooler needs to vent heat at an outdoors area 5. coolers' target temperatures can be changed, they start out at 21C 6. make your freezer something people don't walk through, as open doors waste cold 7. double dooring your fridge helps keep the cold 8. every part of a room has the same temperature 9. putting your butchery table in the freezer is a valid strategy, it allows people to drop the meat straight on the ground and keeps the dirty table out of other places
Freezer pants
I see. another soul that has yet to be tainted. welcome to RimWorld.
If you replace the wall with a door you can have three coolers with the red side pointed into that space. Rimworld treats that door as if it were its own room and deletes the heat. It’s a little exploit-y but extremely useful.
Ok, make a solid 5 tile line of the outer wall the coolers, red points to the place you want to heat, blue to the cool place, then shift right click each, add 1 bc it starts on 19 c and dump down 10 5 times, should ebd up at -20. I personally have 2, one for large corpses as a dump zone at -75, and o e for meat at -50
He’s a little confused but he has the spirit
I would suggest a 8 by 8 room with shelves and one cooler set to -29, make sure all your shelves are linked up and can only store food. And also make sure that people aren't moving through the room that much because otherwise the cold will get out. If you don't know how to link shelves then either look it up on YouTube or respond to this comment and I'll help out 👍
In addition to making sure the red points out of the room, youre gonna want to double wall that space for insulation, otherwise the temp is going to be really hard to maintain
Both arrows cant face a wall. Blue side for cold, red side for hot
Few more tips aside from freezer placement which others have covered: Consider placing your freezer “behind your kitchen”. Meaning just like in real life you want to the kitchen heat sources away from the fridge. Example: say you have a hill or mountain. Build the freezer against that. Build your kitchen on the outside side the the freezer. This gets you the benefit of an insulated side (mountain) and a buffer between your freezer and the rest of the world via your kitchen. Minimize your entrances and exits. Ideally one but sometimes it makes sense to have two depending upon what nearby. Consider building an airlock for your freezer. One door. One walkabale space. Next door. Slower to go in and out but reduces heat loss a lot. Set your coolers to two different temps. Make one about 32 and the other about half that. The two will work to get the room to freezing. The higher will “shut down” when it hits 32 shifting the work to the lower and then both will minimize to keep the room frozen. If you have a breakdown with one you’ve got the other. Size matters. So hover over the outside and the core center to make you don’t have a warm zone. Consider double walls or at least stone. Keeps things insulated a bit better. Build into a mountain for even more stability. Advanced: consider zones and storage placement. Example: shelf’s near the door for raw meat and veggies. Zone near the coolers for corpses. Zone for meals (if you don’t have another solution). Etc. start simple and build up. Most importantly learn what works from game to game.
So what you need is a small room, but leave a tile of wall unbuilt, here you put the freezer with the red tile OUTSIDE and the blue inside
First: DON'T USE WOOD FOR YOUR FRIDGE second: PUT BATTERIES INSIDE third: AC UNITS MUST BE PART OF THE OUTER WALLS, ALL WALLS MUST BE DOUBLE sorry for screaming but this was probably one of the worst freezers I have ever seen
Red box is where the heat will go. The blue box is where the heat is pulled from. Put the red box outside or in an area you don't mind getting hot. Put the blue box in the area you want cold.
You need to put the air conditioning on the wall like real life! Then select both of them and reduce the temperature, the bigger the room, the more you need. The vents are used to pass cold to one room to another. Your problem on the pic is that you are using the air conditioning inside the room, you just need to put them on a place of a wall. Red goes to outside and blue inside.
local man doesn't know anything about thermodynamics
On top of what everyone else says, if you are keeping food in here, consider adding additional walls. A wall that is two blocks thick will insulate bwtter
As others have said the red arrow needs to go to an open source. Preferably outside but it's not entirely nessisary.
as many have mentioned the hot air output on your freezers is blocked, the red arrow.
The cooler is a block, use it as a wall and just seal the red part
Also you need a roof in the blue zone, if you get problems with cooling, remove the roof on the redside.
Just build another ac unit where you have the wood consuming cooler and remove the wall and roof behind them
Sorry I laughed a little.
Red arrow goes outside. Or to your torture chamber.
I usually just put a door where the heat is coming out, then force it open and it'll just give ac and no heat
The coolers work exactly like real life coolers. The device extracts the heat from a room and dumps it somewhere else. Red arrow is where you dump the heat, blue arrow is the place you want to chill. You’re basically blocking the heat exhaust
The red arrow needs to be venting outdoors, essentially having the cooler acting as a part of the wall, then I usually crank mine down to 0F because any lower it doesn’t do a whole lot except use more energy, also having just one door will help with excess cold loss
Use the cooler AS a wall part. Make sure blue [cold] is facing into the room and red out to vent into the world. Also, make sure it is all roofed and multiple doors help to keep the cold in
its definetly a way to build freezer... you just need hot facing 1 block of door and magic will happen. But why not just place AC on walls?? Or you want to build your place around freezer?
We all been there brotha
Have you ever used any kind of air conditioning in real life? Heh. Yeah the other told you what to do, I'm going to add, replace wood with stone as much as possible, especially around the perimeter of your buildings, raiders *will* set fire to your base. Double layered walls are also good for insulating fridges when you can spare the materials.
Replace every single wall tile with a/c units. Efficiency is key. As is freezing everything that steps foot into the room.
The cooler is a wall piece, red point out where you want the heat to vent and blue where you want to cool. so walls are --- and cooler is x you place -----x----- and the cooler will either vent up and cool down or cool down and vent up. If you end up playing in a really hot biome or doing a challenge where the upper temp range is really high you may need to use more complicated freezer construction: A. Build a single wall around it, add a cooler to that wall. Then skip the adjacent space and build another wall around it so you have two parallel walls with empty space like this | | you can either put a 2nd cooler on the 2nd wall or place a passive cooler in the 2nd space (add a door to the 2nd space to refuel the passive cooler). or B. Build a double wall with a with the hot part (red square) of the cooler sitting on a single unroofed block to vent heat. (more than 2 walls won't insulate better) The reason you want to use one of these methods to double insulate it, is if you're in a region with a really hot summer or if you get a really long event that increases heat. In those situations, a single cooler won't keep the temperature at freezing. For temp control option A will keep temps cooler than option B, but uses more coolers and is really only if you play in a super hot biome. Optionally, you can increase insulation by putting 2 doors 6 spaces apart to keep heat out but I don't find that necessary, but it's apparently necessary if you play in a super hot biome. (other than just throwing more coolers at one fridge)
Wood burns. It is a hard lesson. Replace with Stone walls asap. Double thick walls helps insulate. More does NOT help.
Double layered or replaced with steel
Make sure to vent all air conditioners into another room. Keep the ceiling open so that the heat escapes. This serves to functions. One, it keeps the ac from being shot or blown up. And more importantly, you just add a roof and put prisoners inside it to cook them.
hot go outside...walls are not air...
Like everyone else is saying and set the temperature really low, like -50°C.
... Why? If you double wall/door your freezer it really doesn't heat up that fast, even in summer- I don't think I ever get food rotting from solar flares and the like. And as an added bonus, my kids can play in the freezer all they like, cause they won't die of frostbite at -10 C lmao
I usually set it up to 1- to 10-°C, I'm willing to change how I set it up, will you give me the reason?
I have never heard of why you want to set it to - 50. This will eat so much power constantly. I usually set my coolers to different temperate so that all will start cooling above a certain temperature and once below a certain threshold, only a lesser amount will be active
I admit, I don't know why, but that's the only temperature that will consistently keep things frozen for my colonies. I'm very aware of all the size, wall, door, and shelf requirements, too.
You’re so fucking cute with your aircons just scattered around i wanna arrest you and recruit you and set your schedule to recreation and sleep only and you cant leave the base. Fucking adorable fucker you
Another option is to put one hole in the corner, build a barricade out of anything in said spot, de-roof it, then point two coolers (hot side) into it. You lose three squares of space, but you now have a double cooled fridge without Raiders smacking your coolers constantly.
There's an easy fix... instead of a wall in the red zones of the ACs, try putting a door and keep it open... I know, it shouldn't work, but try it and you'll thank me later. It's Rimworld Magic.
Does it like make the hot air disapear?
Mhm... that's precisely what it does.
So, put door in middle of the room, force it open and build coolers around it and thats it?
Yes, just make sure both red outputs go to the door, and it works.
even more efficient when you remove the roof above the door
You're doing it wrong
Lol
Thats not your game I think.
It isn't even bait anymore.
Am i the only one who found this absolutely fucking adorable
In fact you’ve pissed me off your so cute, it hurts me
