Coolant on Mars

[Angst_and_rancor]

I'm trying to create a cooled room using wall coolers and an X loop in the pipes. The problem is that the radiators don't seem to be doing their job. The temperature of the coolant doesn't seem to change from the beginning and end of my radiator loop. I'm trying to build a gas generator room but the wall coolers don't seem to do a thing.

Maybe the Pressure in your Pipes is to low, Or the Pressure in your generator room. This are my first ideas. Have you a screen shot from your setting?

hmmm technical speaking its -75c at night on mars so it should cool your pipes and anything inside them if they are even outside ( but it will not go so fast without radiators on the pipes).

Well my best advice is to make a pipe from your wallcooler and out into martian air.. and then fill the pipe with example "water" ( prime the pipes, fill them with something )..... and on the pipes outside install some radiators on the pipes.
As Hoschi tv say, maybe presure in the pipes is to low, im not sure but i think you need more than 50kpa in the pipe system that you use for cooling. ( inside of all the cooling pipes )
You dont have to connect anything to the end of the pipe on the outside, the fluid run in both directions inside the pipe and end of pipe will not leak what is inside of your pipe by the way

Tip..: if you want something cold, then maybe make an external tank that you fill with cold water.. And then make some kind of system that you turn on at night when its cold, and cool down your big tank.. ( put it in a dedicated cold room might be a good idea ).
Then you have cold coolant 24/7. )

You do need a lot of radiators on the outside pipe/pipes and you do need a fair amount of coolant. I usually go 5MPA on coolant (although that's a lot, so go with whatever works or consider using CO2 in it as well just to have more if you don't have a lot of gas yet). Don't forget to let it sit and "charge" for a while AKA cool off first. There is not a lot of air on stock Mars. Real Mars has even less, so radiators aren't that fast per capita.

The problem is that the radiators don't seem to do anything and I have well over 300 kPa coolant. The same goes for the radiators leading from my water tank. I check the pipe at the beginning of a rad chain and at the end and the temp is always the same. My coolant is going through 20 radiators and there isn't even a point of a degree temperature difference from one end to the other.

I'll try capping off one end of my cooling loop instead of looping it and see what that does.

Pipe ends are sealed and you dont need to loop the piping around like you normally would. The long piping is just one big pipe as long as they're in the same network.

Also you need alot of coolers if you're using it for gas generator and the power sink is a waste 100w each. You're better off filling both the room and outside with radiators and a valve in between. Another way that works too is having 2 controlled active vents in the room from a cooled tank outside (I prefer the tank in a vacuum sealed box with zigzag pipping with radiators). But on Europa you just need passive vents at the end of those actives.

Maybe one big pipe need separations by any devices to make one end got the heat and throw it away at the other end?

You're mixing up Air Condition cooling loops and air cooling loops.
I would suggest creating a loop that draws in air from one side of the room, passes into a zigzag pattern outside (with radiators) and back into the room on the other side where you draw it in. You need to maintain a pressure in the room so have a sensor hooked up with IO to your active vents. If its not cooling enough, expand the zig zag to add more radiators.

I've found building a room with 'nil' temperature and putting the radiators through that room seems to be doing the trick.

need atmo in room then atleast 125kpa in coolant pipe....works on my mars base
