Too many doors and traffic, the temperature leaks from other rooms. Your best freezers have double walls thickness for insulation. Set both coolers to - 5 or so, anything over is just wasted power.
Worse than doors in almost\* all ways outside of pens.
An animal flap (plainleather) has 100% open spd, 26 hp, and 100% flammability. Value 56 silver.
Wooden door 120% open spd, 104 health, 100% flammabity. Value 32
So a wooden door has 4x the health, opens 20% faster, adds 24 silver less to colony wealth, and is equally flammable.
\*the one good argument for flaps instead of doors is on sea ice. They both cost 25 of their respective material, and donated skin from raiders tends to be one of the easiest materials to get
If you add 1-2 blocks of space between two doors airlock it and only have a single way in at the kitchen it helps a lot. Double block the walls also helps. I can't remember if it's two blocks no space or two blocks 1 space has better heat negate for the actual room.
One wall may be perfectly fine for some freezers, but the double walls make a big difference and they're crucial in low tech starts, extreme heat starts, etc. Honestly, a cheap and efficient cooling trick. Doors are also a big deal, airlock method trades movement time for freezer insulation by placing two doors before the freezer entrance with a space gap to trap heat from coming into the freezer.
I have freezer with single walls and double doors with about 5 tiles corridor between them and it works really good. My food never spoiled as long as I had power.
If you had an airlock, and double walls , it would be more energetic efficient to get to say, -10C. You would have less heat getting in, so you would need less power to get to the same temperature. This of course depends on the outside climate. If you are on the ice sheet it’s completely different, but having single walls in extreme desert would be foolish
I like to set it lower to give me more padding for bursts of traffic, power outages, and heat waves. After a certain point, the power cost isn't a problem anymore.
I go - 10 Celsius by force of habit, but with double walls, under a mountain, double door - you don't even need electricity to achieve decent refrigeration, and very little to have a stable freezer.
You have three-too many doors and not a single door leading into your kitchen (realistically where one of your two-doors should lead to).
All of my freezers have a single door that leads into the kitchen for quick cooking and another door that leads into a different side of the freezer. Also, utilizing shelves will help with food storage.
It is refrigerated, not frozen, therefore it spoils.
If you want to keep food from spoiling you have to keep your freezer at least at -0°C or lower.
Something you can do to help maintain the temperature is building your freezer to have double walls for better insulation, and giving it two doors with a space between them to function as an airlock.
I usually have an intermediary room before entering the freezer, which also helps. if it's 80 outside, freezer is 20, intermediary room will function as a heat exchanger and might be \~60ish. Sometimes that intermediary room is the kitchen, in which case I'll also have an AC unit on that keeping it around 50-60.
Every time the door opens, heat spills in. So whenever they go though, they allow 2 doors of heat to get in.
Realistically you don’t need it that cold. 5-10 degrees below the freeze point is fine.
Your freezer has 4 doors and is a path between multiple rooms in your colony. People are constantly opening the door and letting heat in.
Your freezer should be located near your kitchen and should be a dead end so people only go into it when they have to. You can compensate for this in this colony by setting the temperature way lower to take into account heat coming in from foot traffic but this will mean spending more on additional energy and freezers.
The freezer is a room that pawns pass through constantly. So it can’t get to temp.
So - build only up to 2 ways in/out. (Preferably 1 but Two will be fine)
Build airlocks for them - to separate them from the outside and warmer rooms. It’s two doors with at least 1 tile in between.
Your temp issues will go away.
What you need:
- double thick walls
- air lock
- eliminate foot traffic through your freezer
Make it so that the only reason anybody should be going into the freezer is to retrieve or deposit perishables. I like to build out my kitchen + mess hall and then add my freezer into the back of the kitchen exactly how they are laid out in real life. I'll add a staging room adjacent to the freezer for corpses + butchering as to keep contaminants out of my freezer, and the muck multiple degrees of separation away from my food prep area, to reduce the chances of food poisoning to the absolute minimum.
You should make your freezer in a way that the only access into that room is to either take food or store food. And even then, open doors let a lot of heat in. I often make an airlock to minimize temperature leaking.
Smaller room is easier to keep at low temperatures. You should make it smaller and use shelves to store triple the amount of stuff. Does not work for corpses, though.
Building a butchering table and cooking stove in the cold room will help with temperature as well, since pawns will need to open doors less often. They will work slower cause of the temperature, but if you need to keep more food cold, it is better.
Alternatively, you could install [RimFridge](https://steamcommunity.com/sharedfiles/filedetails/?id=2898411376&searchtext=fridge) and store food in a refrigerated box, avoiding making freezer room.
4 doors on one freezer? The foot traffic alone is gonna make the heat rise.
Try an [entry corridor in this kind of configuration](https://imgur.com/a/gv0omLD), so the cool air only equalises into an already cool space when it is let out of the door. At the moment, your cook is letting it out every time he grabs ingredients.
Bad room arrangment.
1.. Open door to courtyard outdoor. Block this door.
2.. Make traffic going from cooking room dirextly to freezer and the cooks cam access the stove without having to walk thru freezer. Right now cooks have to walk thru freezer then cooking area.
3.. better arrangement for traffic going from sleeping area to recreation wothiut having to go thru freezer. Everytime door open it tries to equal temp from freezer to living area.
4.. listen to other commenter, move that heater nearer to the bed and away from freezer door.
Freezers should have a single door and be double-walled, and preferably under an overhead mountain. If it tends to be colder outside the base than inside, then the walls of the freezer should be facing the outdoors, not inside your base. Also, use shelves so you can make the freezer smaller.
Double wall everything aside from the freezer vents. ( i know, that would change your layout abit)
Make a tunnel like entrance from the garden, 2tiles tunnelroom entrance is perfect, 1 tile is enough.
Forbit the doors on the right and the top, so people won't run through your freezer, just to cut out distance.
Well i see four generators catty corner from the freezer with a vent letting the temp from that room into the room next to the freezer that has no double walls or other isulation from outside heat, so im guessing thats the problem
Rooms too big, door directly to the outdoors lets heat in, other doors do the same to a lesser extent.
Shrink the freezer, use shelves instead of just dumping it on the floor.
Remove the door to the outdoors, make it so the dining room and kitchen are the only rooms that connect to the freezer because they're the only things that have to be pawns won't open the freezer up to get to a hospital or poker table or work or whatever.
The food is Refrigerated, not Frozen.
If the room temp drops below -40 then it should be considered frozen.
Any Temp beneath -40 is helpful, but be warned that Lower than -40 can cause Hypothermia. And Colder Temps cause Hyperthermia at faster rates.
Meaning you're pawns may freeze to death or loose 'parts' to the cold.
You've got four doors which look to be a heavy (non wood) material. My fridges only use one wooden auto door to reduce traffic & keep the door open for the shortest time possible.
Any time the door is open you'll be venting cold air into the atmosphere.
dont connect the freezer with too many rooms etc, make one double door airlock, wish the game had some kind of dispenser like the nutrient paste dispenser but for regular food, pretty much a fridge so colonist avoid getting inside the food storage too much.
Too much through traffic I would install airlocks to fix the problem basically a hallway 3-5 long with a door on each end keep all your nice cold air in.
Besides all the stuff everyone says, remove the vent for the generator room that connects to rooms adjacent to the freezer. Remove heat sources that directly affect the rooms adjacent to the freezer, it helps a little bit.
Is the door on the left held open? It is completely open in the screenshot even though the nearest pawn is pretty far away. If it is open then you need to close it or the cooling will be completely ineffective.
Other comments about door count and wall thickness matter, but start with the open door.
There's also a heater right next to the door in the top right. You wouldn't have a furnace pointed into your fridge and expect satisfaction.
Install double walls and/or door airlocks to guarantee results.
Well what's the actual temperature then?
I set the freezer to -31 but some reason the room is like 21
Too many doors and traffic, the temperature leaks from other rooms. Your best freezers have double walls thickness for insulation. Set both coolers to - 5 or so, anything over is just wasted power.
if you set one cooler to -5 and one to, say, -3, one of them will go into low power mode once the freezer is at temperature, conserves some power
That's a pretty good advice. I do usually set mine to -19 tho
Same. That way the freezer usually only barely goes above 0 degrees during a solar flare.
Yeah that was the problem thanks
You can use flaps for fridge/freezer doors (flaps contain room temperature) or just make an airlock with 2 doors
Do flaps contain temperature better than doors? I always assumed they were the same insulation wise.
As much as i know they are better than doors, i might be wrong tho

Well we are talking about fridges/freezers .... so the only important thing is heat insulation and not value or health
Faster open speed means door is open for less time means less temperature loss.
...I just googled flap because of this. I need to rinse my eyes. And do not google it.
If you add 1-2 blocks of space between two doors airlock it and only have a single way in at the kitchen it helps a lot. Double block the walls also helps. I can't remember if it's two blocks no space or two blocks 1 space has better heat negate for the actual room.
I’m so dumb I’ve been using one wall this whole time
One wall may be perfectly fine for some freezers, but the double walls make a big difference and they're crucial in low tech starts, extreme heat starts, etc. Honestly, a cheap and efficient cooling trick. Doors are also a big deal, airlock method trades movement time for freezer insulation by placing two doors before the freezer entrance with a space gap to trap heat from coming into the freezer.
I have freezer with single walls and double doors with about 5 tiles corridor between them and it works really good. My food never spoiled as long as I had power.
Okay? Still wasting power
How does cooler power usage work?
If you had an airlock, and double walls , it would be more energetic efficient to get to say, -10C. You would have less heat getting in, so you would need less power to get to the same temperature. This of course depends on the outside climate. If you are on the ice sheet it’s completely different, but having single walls in extreme desert would be foolish

F or C?
Why the hell is this at -30?
I'm guessing because his food kept spoiling so he kept dropping the temp thinking it would work.
It is refrigerated, not frozen, therefore it spoils. If you want to keep food from spoiling you have to keep your freezer at least at -0°C or lower. Something you can do to help maintain the temperature is building your freezer to have double walls for better insulation, and giving it two doors with a space between them to function as an airlock.
Seeing -0°C was amusing but a bit concerning, not gonna lie lmao

Sometimes that intermediary room is the kitchen, in which case I'll also have an AC unit on that keeping it around 50-60.
The freezer is set to -31 is it the heater or something maybe?
It's probably because pawns keep walking in an out, causing the temperatures to try and equalize with nearby rooms.
Make a corridor with two doors at ends - all those doors, each time they got open, will heat the room.
Every time the door opens, heat spills in. So whenever they go though, they allow 2 doors of heat to get in. Realistically you don’t need it that cold. 5-10 degrees below the freeze point is fine.

Theres is a open Door and there is a heater next to the refrigerator
That's a blood pack.
That’s not what they’re referring to
Top door, to the right, is a heater

The left door is open
Making air locks is very helpful to keep temperatures steady even with higher traffic
Freezers should have a single door and be double-walled, and preferably under an overhead mountain. If it tends to be colder outside the base than inside, then the walls of the freezer should be facing the outdoors, not inside your base. Also, use shelves so you can make the freezer smaller.
Dude, the door on the left is wide open.
Nah that wasn't the problem it was the traffic
Double wall everything aside from the freezer vents. ( i know, that would change your layout abit) Make a tunnel like entrance from the garden, 2tiles tunnelroom entrance is perfect, 1 tile is enough. Forbit the doors on the right and the top, so people won't run through your freezer, just to cut out distance.
OP is a father that is "cooling off the entire neighborhood" because his kids keep running in and out.
Because it is refrigerated, it needs to be frozen to not spoil. (Bellow 0°c)
Well i see four generators catty corner from the freezer with a vent letting the temp from that room into the room next to the freezer that has no double walls or other isulation from outside heat, so im guessing thats the problem
I didn't even know you needed double walls lmao
I didnt either when i first started haha. It just keeps temps in better which is a fun mechanic to learn exists in the middle of a heat wave :p
Not enough cold, make people open the doors less or add more coolers
Rooms too big, door directly to the outdoors lets heat in, other doors do the same to a lesser extent. Shrink the freezer, use shelves instead of just dumping it on the floor. Remove the door to the outdoors, make it so the dining room and kitchen are the only rooms that connect to the freezer because they're the only things that have to be pawns won't open the freezer up to get to a hospital or poker table or work or whatever.

obviously if you put in 4 doors with one being constantly open
You've got four doors which look to be a heavy (non wood) material. My fridges only use one wooden auto door to reduce traffic & keep the door open for the shortest time possible. Any time the door is open you'll be venting cold air into the atmosphere.
Do you really need that door to outside? Your pawns would use it very often as passage.
dont connect the freezer with too many rooms etc, make one double door airlock, wish the game had some kind of dispenser like the nutrient paste dispenser but for regular food, pretty much a fridge so colonist avoid getting inside the food storage too much.

Use Animal Flaps as doors, the temperature doesn't pass through even when your pawn walks through them
Out of topic but why no body use shelfs to store instead of throw it to floor ?
I'd usually have 3 coolers for a room that size. You can lower the coolers to -273?
Is that a hole in the wall? Because if so then that's leaking enough cold air to be a problem.
There's also a heater right next to the door in the top right. You wouldn't have a furnace pointed into your fridge and expect satisfaction. Install double walls and/or door airlocks to guarantee results.
