cold water pipes

[lissa_981]

I am tryong to build a system for farming sleet wheat, and was attwmpting to run water through a cold room with lots of weezy plants, I was using the regular pipes with thermo conductivity to cool the water before running it to the tiles. I almost had the system started then my pipes started freezing and breaking. I see materials that are designed for increased temps but nothing that is for cold temps.. Can anyone advise?

you don't want the water in the pipes to go below 0c, the most obvious trick is to build the wheezewort's plant pots on top of horizontal mechanized doors which are connected to automation sensors. Set the thermo sensors to activate when temperature goes below 1c, when the doors open the wheezeworts become inactive due to not having a 'foundation' below them.

Also, radiant pipes are much, much better to use.

easier to show it with a pic, here's my over-the-top setup!

I see, I am revising to include a gas line that followa the water line from my pincha/power/oxygen generator area I really needed to cool the O2 anyway, it seems to keep the pipes from freezing, but now I'm stuck at 8 d for the plants intermnal temp.. I know I could use clorine or hydragen but I was trying to avoit the neccecity of an air lock.. IAs you said earier to show, give me a few and I'll post a screen shot or3

oh one other thing that makes a difference is cooling the dirt: when it drops out of the compost heap it's around 70c, and most of the dirt you dig up is around 20c-30c.. those kinds of temperatures can upset the temperature of the crops; by storing the dirt somewhere cold you make it work for you instead, if they are adding cold dirt to the farming tiles that would actually help you reach the right temperature.

note this is a little early in the research trees, I just researched plastic but do not have a refining process set up for it, and I have not yet began to use autlmated systems.. I know I need to figure it out but I'm seeing what I can do w/o messing with them

edit: just realised I should have let that run for a sec after I reloaded.. I don't run steam overlay normally so I had to save/exit/enable/reload. thise things all have inputs

[Strygald]

The problem with wheezeworts is that if left alone they'll lower the temperature around them to -60c, now that's really hard to do in oxygen and in your setup.. but if they manage to lower the temperature to even something like -4c you're most likely going to get a lot of broken water pipes. The only way to control the temperature change is to use automation, either by sitting them on doors or having doors between them and the crops that open and close to block/slowdown temperature transfer.

Since I didn't notice anyone saying it and someone might get confused, the pipes have no problem with the low temperature, they are breaking because the water in them freezes and thus becomes solid.

[lissa_981]

correct, that is why running the hot air pipes on the same line as the cold water pipe is working to keep them from freezing, they are unable to get quite THAT cold dispite the ambient temp. The water isn't getting quite as cold as I would like currently (aroung 10d) The system seems doable t with this set up though after a few additional modifactions to the design, mostly related to spacing of the wezzy plants.

Just shorten the pipe inside the room with weez plant to make sure that the water doesn't become so cold. I don't know what is magical length.

dont bother farming until you have like 20 dupes, preserve wild plants!!!

Oh wow thanks for this tip. I'm going to start storing my dirt in the room I use for my cooling loops.

YEah I agree. I don't farm sleet wheet too much trouble. I keep a small farm of lice and just enough bristleberries to fit around my printer pod (because it's a source of light that doesn't generate heat) and seem to do just fine with that + wild for 12 dupes

[lissa_981]

while I see your point, If I'm making a cold room anyway (and I think I want to to allow for easy air cooling, I feel I might as well do a little farming there. I do love multi purpose rooms. I tend to not like leaving things to chance, so I've been focusing on secure supply chains for 1) food, 2) O2, 3) power 4) temp 5) H20
at that point I can feel good about tackeling some of the advanced refining, logic systems and generally proceeding to the end game. As a begin to understand those systems I'm sure my build order will change, but as it is I want to get this last system figured out ( again it started more as a cooling room to control the ever rising temp. of my base )before I move on to the next system. That base was designed to hold 25-35 Dupes BTW that seemed a very appropriate number to carry them through till late game.

As I am finding right now, Automation is amazing. From making sure my coal generators are not wasting resources, to creating a system of purification that completely destroys 100% of the food poisoning germs in my polluted water, to:
I would think: your sleet wheat farm.

Currently I'm trying to make do with wild plants, seeing as how with 10 bristeblossoms, and my critters, I literally cannot eat the food I produce.

But Sleetwheat for bread is my goal since I cant seem to get the massive deco bufff to really high.

As for your situation, why not use automation? (Big love to Styrgald about the info on the dirt. or is that dirt on farming? snicker*)
Dirt could be placed in cold biomes (where you'd prob want to have your farm). But lets say you want it nice and close to base.

Isolated cold room (apparently I cant build with abyssilite, but I read ceramic is good?), and then set up weeze warts on air locks. Radiant pipes snaking through the room. (both of these were said), (*I read that wheeze warts actually pull air in from the bottom pixel, and expell the cold from the top, but i dont know if that's true), and insulated pipes after the cold room.
THE AUTOMATION: May as well set up a thermometer or 2 in the most critical points, and try to keep the room from dipping below freezing. And then Use a liquid shutoff valve, automated to only open if the temperature of the water in the pipe is in the 1-5 range (or w/e you want)
that way the room will self regulate, and the water leaving it will always be perfect temperature. :)

My lack of automated systems is entirely do to with my way of learning these type of games I like to explore 1 system at a time building them house of cards style. I observe stresses to systems and see how to improve them untill I'm satisfied then move on to the next, tweeking them as I learn more advanced mechanics. This is my issue and I understand that but there you have it.

So, for context: I feel good about my farming up to the pinchas, and had planned on focusing on learning the automation system next, but before I could really start I had heat issues, lots of heat. This caused me to decied on a cooling system and I wanted to try a low tech option first (low power as well as this was a secondery concern) since I was going through the trouble of making a cooling room it seemed a appropriate to farm in the room too. I think I'm happy with the proof of concept, there are a few small issues still, mostly in terms of air cycling and moderating it's flow and volume, but that's only when I'm about 16-20 dupes in so I'm hopping this reset I'll get a chance to start automating before I over stress my ventalation system. I was just beginning to use gas pressure regulators to make my air flow more efficient but things happened.

Wheeze wart does work like that, that's why it's harder to cool the bottom of the room, the top stays pretty stable. After I set the Hot gas pipes (thermally reactive) to go through the same space as the water pipes the temp stays stable at aroung 0-5d for the water. It's imprtant to note the temp is very stable as the air is contunously cycled out of the room (untill there are isses with the vents that is ) I have changed up the water piping into theWheat plants as the air in the vent on the bottom was wrecking my temp (and by that I mean that water was at 5.6) I'v also considered running the air through a crawl space with insalated tiles on the floor and cieling and pump as much air as possible (not sure it I can create a vaccume but that would be the ideal) not sure if it's worth the effort but it's on the table.
