Of Refrigeration and Freezers!

[Bandus]

Greetings! I have attempted to make a freezer for my raw food/prepared meals, however, I seem to be having some trouble. Please see Exhibit A:







It is warm outside, 70-80 degrees and this room seems to be stuck around 39-40 degrees constantly even though I have the industrial freezer set to 10 degrees.

I am trying to mine out behind the freezer because I am concerned that the heat output is radiating back into the freezer. Does anyone know if this is a correct assumption or have any thoughts on what I am doing wrong? Thanks!

Cant see the image but how big is the room?

[Bandus]

My apologies, I have updated the link so the picture should display now.

The room is 5x14.

hmm all that rock around will insulate a lot. Whats the temp of that vent space? you might be right in your assumption that its the problem.

[Bandus]

The temp behind the freezer unit is 260-265 degrees or so. Do I need to mine out more space behind it?

no place for all the heat to go, venting into a sealed rocky room. Does the rocky room have a roof, where you are venting? Also the open corner by your industrial cooler allows very quick heat transfer between the rooms. you need to vent the cooler to the outside world.

unfortunately it has a mountain over it so no matter the size theres nowhere for the heat to go. You need a vent to the outside really...

Take the roof off the "vent chamber" I don't know if it matters, but I've never used a fridge  that vents the "hot" side to anything but the outdoors. Also be sure you are using an airlock so that foot-traffic through your door doesn't let the cold air out. [edit: sorry, the other replies posted while I was distractedly typing my response.]

On cold biomes, the best practice is to position the cooler opposite of a growing room to help keep plants within optimal growing temperature...

Also, try setting the temperature around 0C or 32F only, if you aim for lower you're essentially making the unit work harder and thus expel more heat...

Also, use only 1 door (auto) to maintain a better temp seal inside your freezer...

Also, maybe you can make a long venting tunnel through the mountain that exits somewhere close to your base entrance. With a little effort, you can make raiders enter said tunnel and thus greet them with a furnace blast to the face!

EDIT: Another also...

Tunneling to the outside and placing a vent has resolved this, indeed. Thank you!

A 1 tile heat sink room works just fine for ordinary climate control, but it appears freezers need to either pump heat into a much larger room or the outdoors to maintain freezing temperatures.

This. The heat does bleed, without a vent you'll be fighting a losing battle.

Check this short video maybe.
Also i've always made mine so that the heating part point outside too (or in a greenhouse) and set to -9°C.

EDIT : After you can make this one ^^

Definitely vent the heat buildup behind the freezer. There was some discussion in various parts of the forum bout heat bleeding through walls. And I believe the general understanding was that heat can bleed through in some part if its a 1 block thick. Therefore to enable an effective insulation for both hot and cold, a 2 block thick wall is needed.

As one of the guys involved in that one, I tried a 2 thick wall, and there was still heat bleed. So my recommendation remains a wall, space, wall set up for a freezer.
