| − | When an AC is used for heating, its waste pipe can get extremely cold. The same goes for using passive Radiators on the Moon or on Mimas (keep the radiators exposed to sunlight to prevent the pipe temperature from getting too low). The best gas choice for cold pipes is Oxygen, since it is the hardest to liquify (-111°C at 6MPa), and all of it should (not properly tested!) turn into a liquid before it freezes into a solid. If the pipe pressure is above 6MPa the excess Oxygen will start to condense when the temperature dips to - | + | When an AC is used for heating, its waste pipe can get extremely cold.

If the pipe pressure is above 6MPa the excess Oxygen will start to condense when the temperature dips to -111MPa. Attach a "Passive Liquid Drain" is a good way to protect the pipe, any liquid Oxygen will be removed from the pipe before it takes any damage. Instead of using pure Oxygen, crushed Oxite will do just fine, the Nitrogen will condense first and remove itself through the drain. |
