Coolers wont cool enough

[Qualle]

Hey, my coolers wont cool enough the room is between 0-5°C even though my coolers are on -70°C whats the problem, wrong battery placement?
Here is a picture of my base. https://imgur.com/a/aJnAorH

Looks like it should work.  Are the coolers facing the right way, and the chimneys are unroofed?

The hot output of the freezer are just 1x1 tiles and maybe not even unroofed ?
I bet at these 1x1 tiles is a very high temp.
Then the cooler can't cool because they can't get right of the hot air they generate.
(lies mal die bedienungsanleitung deines kühlschranks, da steht bestimmt auch das der hinten genug platz braucht damit die luft dort zirkulieren kann).
Best solution is that the hot output goes into some outdoor tile, or you can use it to heat your base.

Yes, your "chimney" for the cooler is just not large enough.  2x2 will work; 1x1 will not.  (I assume the interior is unroofed; if roofed it won't work at all.)

no, 1x1 unroofed chimney works

Wait, what? I can have a dozen fires in a room and a chimney 1 by 1 will equalize it with the outside.

Fires max out at 28'C.  A cooler can throw off a lot more heat.  I'm not sure exactly how much heat the hot side of the cooler generates, but I think it's more than the electric heater / campfire.  And in any case it doesn't have the temp limit.

Out of the three coolers, the one at the top is inverted to throw hot air inside your freezer, the blue arrow is pointing out and the red arrow is pointing inwards.

LOL, *that* will do it every time!
