Building a freezer in a jungle biome

[Listy]

Can someone explain to me a little bit about this venting I've been hearing about? I'm a bit confused as to what it is being used for as some comments make me think one thing, while another is making me think of something else.

On one hand, some comments give an obvious and logical impression, creating an escape for the hot air generated by a cooler on the outside of the freezer, so that it doesn't build up.

And then there are comments that seem to imply... venting the freezer interior itself? Is this actually something people are doing or am I just reading those comments wrong because it seems to me that having a hole in my freezer roof would only serve to let the cold air out faster. There's enough heat escaping through the doors and walls...

?

We were talking about this issue here, when I had problems a couple of days before:

My reply #7 has details of venting, including a diagram.

This is how the freezer in question looks like now, I tried building the outer wall as insulation when I was experimenting with venting the coolers inside. That many coolers and not venting outside had the temperature at about -5 to -10 celsius when it was about 30 degrees outside. Opening up a roof tile made the coolers easily reach the target of -19 celsius in the same weather. Question is, does the wall help insulate now as well or is it just going to be decoration?

i always have my coolers in a 2x1 area with the roof open at the hot side, so they vent out. makes them work much more effectively.

Yeah, it appears venting the exhaust outside is so much more effective in the current build than to vent it into the rest of the base. The setup shown with an unroofed exhaust area is a bit excessive. I could probably freeze a room at least twice the size if not (a lot) more

Uh... I'll just build 30 batteries and 30 solar panels, slot in half a dozen coolers and crank 'em down to -20C until the temperature mechanics are tweaked again.

Just stick with a simple 9x9 room with a steel or stone walls with 2 freezers for those heat wave days.  if you need more space for food build another 9x9 room right next to it with a joining door with 2 freezers as well.  I never have problems with this type of style.

But it does seem heat is being lost a bit too fast, I'm considering rebalancing this. Maybe for a hotfix (among some other things).

In the Alpha9 test builds, I thought the temperature swings of rooms was quite reasonable. I did take notice that the released Alpha9 is moving back towards a more erratic swing with room temperatures fluctuating by as much as 8 degrees every second when a door opens etc. Kind of reminds me what the earlier Alpha8 builds were like until the normalization was smoothed out a bit.

I'm getting the impression that this is going to be one of those features that is going to be very tricky to nail down. Might be a few versions before all the kinks are worked out. Might even go through a few different variations of how it works, too.

Nothing to be unexpected, though, since it is still an Alpha game. That is, of course, the time when features are most widely added and experimented with.

I've only just started playing, but I'm enjoying it quite a lot. It's complex but also simple. Sounds like a paradox, I know, but that is how I would describe it. I eagerly await seeing just how far it can be taken.

I do think the erratic temperature fluctuation is due to the doors more than 'bleed' through walls, even on hottest days in jungle or desert biomes.

I've eliminated one of the two doors on both of my freezer rooms and it helps but not to the stability it was before A9. The problem with large scale food production when you have more than 5 colonists and prisoners is that your cook or cooks are going in and out every 30 sec for more veg/meat and your hunters/farmers are going in and out to bring in fresh supplies so the door is non-stop opening and closing. I'm wondering if an airlock system of two doors would help prevent too much cold air loss. Anyone tried this?

Edit: I'd also like to say I really don't like how quickly food goes from a frozen (won't spoil) state to refrigerated (spoils in x days) state when that temp. fluctuation happens. This needs adjusted. That constant re-calculating can't be helping system load and isn't even realistic since food that's fully frozen won't un-thaw that quickly if the power goes out or the temp. drops to 1 degree above freezing like that. Because I have a door / temp. issue, I have to keep temps much lower than hovering right around freezing otherwise I have that constant fluctuation every few seconds happening with the freezer rooms. This needs some tweaking I think. When a solar flare or power outage happens, I think food should stay frozen for at least half a day or so before it 'thaws' to a refrigerated or fresh state.

Works for me, keep it at -5 C, havent had problems yet, the kitchen gets rather cold though, around 10 C.

Bet the temperature in the corridor is ~100c, with 4 coolers venting into it. Extending it one square away from the edge on the mountain and creating a no roof square would vent that heat out, and you wouldn't need so many coolers.

One possible solution to this is to have two freezers fairly far apart, each with equal priority stockpiles for food.

The cook can use either one to pull food from (set this up in the bill) but they will first draw from the one closest to them. That should also be closest to your food production, so it is almost full all of the time.

Therefore the surplus stacks of food will go to the other, further away freezer which means the door-opening on the cook's freezer is reduced.

In the early Alpha8 test builds I think a number of the testers used airlocks for this purpose (I did anyway). When the temperature system was first being integrated, it started out rather jumpy, and an airlock definitely helped. Since the temperature transitions were smoothed out leading up to Alpha8 release, it was used less and less.

I haven't tried it on Alpha9, as I've been working around the issue by setting the temperature low enough so the swings don't go above freezing.

You're right about the instant thawing and freezing of food. This would be an easy addition later if Tynan desires once the system is stable. Technically speaking, the freezing point of water is not really when food is considered frozen anyway. It's more like 0 - 10 F. All easy tweaks later on.
