Oxygen Not Included: Episode 8: Pumping Gas

#oxygennotincluded
Oxygen Not Included is Klei's excellent "space-colony simulation game" in which we "will need to master science, overcome strange new lifeforms, and harness incredible space tech to survive and, possibly, thrive".
We won't be thriving...
We redesign our hydrogen/oxygen capture room and begin to explore farther afield.

Thank you for the vid ! Here are some infos complementing what we saw in this episode :
1. In your current electrolyser room, you can automate the activation of the gas pumps with an Atmo (pressure) sensor ( send green if pressure above 450 g/s). I would link the temperature sensor (mesuring in the oxygen layer) to the electrolyzers. Your oxygen only needs to be cooled if you inject it back in your living quarters of your base (below 37°C for duplicants or below 30*C for crops) ; it doesn't matter for Atmo suits, the game won't penalise you unless the Oxygen temp is above 72°C (scalding limit).
2. Anti-Entropy Thermal Nullifier (AETN) : is a heat deletion device that uses 10 g/s of Hydrogen in order to function (lowest temp that the AETN allows is 100 K/-173.15 °C).
The sensible way to use this machine (without access to ethanol or petroleum as coolant) is to fill the atmosphere surrounding it with Hydrogen, and at least Granite Tempshift Plates. On one side of this "cold room" you create a heat exchanger with metal tiles and radiant liquid pipes going through those tiles (might not need to be radiant depending on the coolant used).
Early game I would use Polluted water, as a coolant (freezing point -20.65 °C ; you have until -23.65°C for phase change).
You limit the cooling with a thermo sensor linked to a gas shutoff in order to stop the cooling going past the freezing point of your coolant.
Or the second method is to exploit the fact that no phase change occurs in a pipe when less than 10% of the maximum allowed volume is circulating in the pipe : to do so, you limit the flow of coolant to 1000 g/s with a liquid valve. This method avoids the pipes from bursting but is slower because you divide your heat capacity by 10.
Comparativly, in Hydrogen, the AETN deletes as much heat as 7 Wheezeworts moving the max. 1kg/s of gas (-80 kDTU/s).
For example, this deletes the equivalent of heat produced by 9 coal generators.
But I recommend using this cooling for the oxygen output of the electrolyzers and cooling the hydrogen generators (and using the water coming from the Cool Steam Geysers as input).

Atmo sensor! That's what I was looking for!
I am now pumping some of that oxygen back into the base, so I'll keep the Wheezeworts in there for the moment and keep that oxygen below 30c.
I'll have to see if I can find some visual representations of the AETN setup. I think I understand what you're saying but I also think that I need to see it in action before I really get it!
Thanks for the tips. They are really useful!
