Need help with pressurizing and cooling my base

[Ghostpro71]

Hi all I've heard this is a great community so I want to say thank you for all your help.

I have a few questions:

1. I built 4x4 room with an airlock and am curious how to exactly pressurize this room. Is it normal to drop Oxite in the room so it melts? What is the normal pressure for a base or even just a room? Is it 100 kp's?? Should I be aiming for 70% Nitrogen, 26% O2, and 4% CO2?

2. For cooling, what type of gas makes for the best cooling? I've tried Nitrogen, Oxygen, etc., but when the cooler runs the gas gets really hot inside the pipes. Is that normal? I've put the pipe radiators on but when the wall cooler runs, the pressure in the pipes keeps rising and it gets hotter and hotter.

Not sure what I'm doing wrong there.

3. If I want to use multiple wall coolers in different parts of a huge room later on, do I need to have separate logic chip components for each wall cooler? Can you use 1 set of logic for many wall coolers?

1. I build bases with 100kpa. around 65%N, around 28% O and around 7%CO2. That way my plants also grow without problems. I only use tomatoes, pumpkin and soybeans.

2. Pollutants has the best cooling effect. I use the AC (its the filtration thing you need to build) and then I put X in the waste pipe and move the pipe outsinde the base with radiators on it. If I have plants the AC only need to cool as the plants slowly heat the base. You dont need much plants to achive this. Only a few.

3. I dont use coolers, but if you use a batchwriter to write. Batchwriter will write to all of the same devices on the same network.

I figured AC units work much better than those wall coolers.

I appreciate the help.

By the way, is it normal for the pipes outside of the base getting really hot?

So when I setup the wall cooler, I had regular pipe outside the base with about 10 radiators on it, filled with C02 I believe it was, and when I had the wall cooler ON, the pipes started getting really hot. Then when I turned off the cooler, the pipes cooled down again.

This is normal right? It didn't matter how many radiators I had, they seemed to skyrocket in heat.

Yes, the exhaust pipe heating up is quite normal. There's some newer tutorials, but I found this one by Bushwackah quite easy to follow along and gave me my first understanding of how the wall cooler works.

100kPa is good but you don't really need it, I usually go for 50 kPa, plants are fine with this pressure and unless you have a pressure diferential to reach with the exterior (basically because it's Venus and you are not using the most sturdy walls, padded walls) you don't really need 100 kPa, less work to fill it with your breathable gas.

At the moment we don't need to use Nitrogen in our environment but perhaps this will change or you do it just for the sake of it. In your greenhouse you need 5% CO2 or some plants will die.

Pollutants and CO2 are the best for coolants, but X has no other use unlike CO2, so yeah, pollutants are great for coolant. What happens in your AC waste pipe is perfectly normal, if they cool down the room the pipe goes hot, if they heat it up the pipe goes cold. So, usually you need to cool down the waste pipe so it stays with good efficiency.

This is easier in planets like Mars or Europa (just put the waste pipe in the exterior with some radiators) or can be a pain in the tail like in Venus.

You keep talking about how tough Venus is, I'm beginning to think you don't like it there.

How much coolant in the pipe is optimal? Don't you need a minimum of like 12kpa or something?

[JeanDeaux]

Can't say I've every played around with it to find optimal. I usually just equalize it with the room pressure (usually at least 75 kpa) and it works just fine for a small greenhouse.

150 kPa at least, 1 atm if you can.

I am working actuallly in a Venus base on Stationeers difficulty...700 days.

I love Venus but it's tough as nails: no ices (my game bugged though and it got ices but I just don't mine them), no seeds in the lander, no natural source of Hydrogen or water, 463ºC day and night, 250 kPa pressure, mining is a torture with those weird wind physics the devs still didn't fix or tone down.

No rest for the wicked in this hellhole.

I read somewhere that the devs have been working on the problem with mining pushing you into empty voxels. Something with how, if there is a vacuum then the atmos more slowly fills that voxel so you dont get pushed around as much or as hard. With the pressures on Venus though, I'm sure its still a bit of a problem. I'm sure its tricky to fix though. You could make it so that if you mine out a ground voxel then it just spawns in planet atmos in it's place but that would lead to issues with mining out the floor of a base and just spawning gas.

My mind is racing thinking of how that could be exploited with the terrain filler tool.

1.
100 KPa is the normal pressure, but 80 kPa works fine too, 4-7% CO2 is good I think,
more than 20% O2, and the rest Nitrogen, no pollutants!

2. Pollutants (X) or CO2 should be best for cooling, I use around 500 kPa pressure,
works fine

3. with a logic "batch writer" y can adress all the coolers or all the heaters at the same time within a electric/data - circuit (you can split your circuits with transformators, no data pass through them)
btw: Individual addressing works with a "logic writer"

Nothing is wrong here. Since you cool the room, heat (energy) has to go somewhere. Therefore, the connected pipe gets hot (this is where the heat is pumped or exchanged!) You can only get rid of it with more radiators or a heat exchanger in the outside area (with liquids). So, everything is normal here!
