Why is it so hot?

[Cardbo]

Granted, there's a heat wave, but I've got a walkin freezer with no roof, its set to -2 degrees on both refrigeration units, an airlock, and its still 25 Celsius inside the fridge. 

Why?

EDIT: Sorry.  Meant to say there was a roof.

I think you have youre coolers faced the wrong way.

I don't think so.  Its always been blue is inside the room.  Red is outside the room.

[JO01]

You sure?

[silenced]

There's something called "Heat Wave" going  on in your map, and the two coolers are WAY to few for that LARGE room. You should add at least 4 more just for cases like this.

Additional, setting it to -2°C may be fine for saving energy, but it's better to set it to -11°C.

ummm, walkin freezer with no roof?

no roof means its outdoors...you can't control outside temperature.

Also, to cool a 13x13 room, which is what i use as the default, you need about 3 coolers...i use 4 because 3 won't cut it in a heatwave.  Your freezer is even bigger.  You put a window air conditioner in a gymnasium in the summertime and turn it on, and i don't think you'll notice much...Bigger space needs more ACs

Lastly, make sure your ACs are all set to the same temperature...its embarrassing to find out you set your first cooler to freeze the freezer, but the other ones are just set on default.

Ok, so the room is too big.  Might be better to go with multiple smaller rooms.  Whats an ideal size room with 1 cooler?

[REMworlder]

Yeah, the room's really big for only two coolers. I wouldn't expect any noticeable change to start until you have 4+.

[Limdood]

you could try multiple 5x5 rooms w/one cooler each...see if that's enough (it might not be for a heatwave).  Get em all in a row and set each one to hold a certain type of good.  It'll look neat even if it loses a bit of efficiency.

I prefer my 13x13 (not including walls) because it is my ideal modular base design.  13x13 will fit a trade beacon perfectly in the center of the room (it'll need a support - i use 2, one on each side of the beacon).  You can also divide it up into 4 6x6 bedrooms quite easily.  My latest base has 12 of these 13x13 rooms....4 storages, 1 dining room, 1 prison, 1 generator room (solar and geothermal), 4 quad-bedrooms, and 1 last module with 2 bedrooms and a 2-bedroom-wide medbay.  Houses 18 colonists with oodles of storage space.

As I've said before, it's not only the size of the room but also the ambient air temperature that affects how many coolers you need. Heat leaks, remember. And your freezer is not exactly insulated either.

And you probably *do* want to stagger cooler temps for efficiency reasons.

Interesting.  I'm assuming that having 3 coolers at -10 and one at -16 is kind of what you mean?  so that the 4 coolers work to get it to -10, then 3 of them go into low power mode?

Better yet, first cooler set to -10, then -8, -6, -4.... most of the time 2 or 3 coolers are running at low power, and only kick on when needed.

[Limdood]

yay! i learned something in a thread where i was trying to GIVE advice!  I LOVE when that happens!

Yes, but I usually make them colder, like -21'C, -20'C, etc.  I like my frozen food FROZEN.

The coolers are placed correctly, but don't produce nearly enough cooling for that big room in a heat wave.  You'll probably need 4 coolers to get that big room to your target temp.  You can put 2 coolers where that little 1x2 open area is and make that 1x2 area unroofed.  I do that for internal rooms that I want to freeze things where there's no outside walls.  All you need is a tiny little enclosed room and remove the roof and the hot exhaust of the coolers doesn't ramp up the heat (it'll stay the same temp as outdoor ambient).
