Yes, Co2 and compressed air has a limited supply and has to be replenished on the surface. This is something nuclear powered submarines don`t have to do since the reactor produces air.

Let me go into more detail so there is no confusion about how a modern sub works. A nuclear reactor does not produce air. CO2, CO, H2, and O2 are all keep in balance by 3 different atmosphere control machines. A scrubber removes the CO2 from the air by using a chemical called monoethanolamine. A burner removes CO and H2 from the atmosphere and spits out CO2 and H2O. Oxygen is produced by an Electrolytic Oxygen Generator which breaks the bond between H2 and O in H2O to produce H2 and O2. The O2 either goes directly to the atmosphere or is stored in a series of flasks for later use.
Compressed air is one thing that that we still need to bring air from the outside inside in order to have any air to compress. Prior to submerging the boat you would be running your air compressors to get as much air as possible into the air banks. Once we submerge if we need to put more air into the banks we could run the compressors until the pressure in the boat dropped to a certain point. To get the pressure back up you use the snorkel while at PD to draw more air into the boat. Since it is possible to put a positive pressure in the boat, you would do just that to limit your time near the surface.
As far as the game is concerned, whenever I play one of the modern boats the first thing I do is shut off limited O2, everything else can be left on. |
