'''Here are two pictures of the atmospheric pipe system. Right one is a "simplified" version of the left picture. Yellow circles representing the filters which filter out a certain gas from the Waste In -gasmix. The light yellow circle near the lower middle represents the mixer which mixes N2 and O2 into a breathable air mix.


Atmospherics is pretty simple, but the pipe layout makes it slightly confusing for the untrained eye. There are 4 major pipe "loops":
<br><br>
* The '''<span style="color:blue">dark blue pipe loop</span>''' is the distribution loop. It sends air to all the vents on the station for the crew to breathe.
<br>
* The '''<span style="color:cyan">cyan air mix pipe loop</span>''', which is specialized to mix and provide the air mix to the distribution loop, and is used to fill air pumps outside the front door of Atmospherics.
<br>
* The '''<span style="color:red">red/<span style="color:green">green</span></span> pipe loop''', which retrieves the gas in the station via the air scrubbers (red loop) and passes them through a set of filters (green loop).
<br>
* The '''<span style="color:yellow">yellow</span> pipe loop''', internal to Atmospherics, which is used for custom gas mixes that can be fed into the canister charging station in the middle of atmospherics, or fed into the mixing tank.
<br>
The tanks (the small rooms in space just outside of Atmos) of the station's atmospherics network, unlike in the rest of the station, are rooms filled with very high pressure of the appropriate gas. The output of these rooms are controlled by their respective Supply Control Computer, an on/off valve, and an output pump for each loop. Note that '''these rooms can be depleted''', especially if [[Traitor|someone]] makes a hole in a tank's external wall.


To understand how the breatheable air mix is mixed, try following these steps and looking at the map at the same time, it starts on the south end of Atmospherics, like so:
# The gasses are pumped through the  '''<span style="color:cyan">cyan tubes</span>''' from their respective tanks ('''N2''', '''O2''').
# They are mixed in the air tank ('''Air''') to a 1/5 mix of O2 and N2.
# The breathable gas is then pumped through the '''<span style="color:cyan">cyan loop</span>''' to the north of Atmospherics.
# And finally it's pumped into the '''<span style="color:blue">dark blue distro loop</span>''' and out to the station for everyone to breathe.


Next let's make up an example situation to see how the waste system works in action:
# Scientist Bill messes up and fills the [[Toxins Lab]] with plasma but fortunately manages to evacuate the room safely.
# Being an otherwise ideal situation Atmos-wise, the Toxins Lab's air scrubbers have been set to filter out all hazardous gases (they're not set by default, this has to be done through the Air Alarm manually or by asking the AI to do it) and plasma starts to get sucked through the scrubber into the waste pipes.
# The plasma arrives to the Waste In -loop (the red pipe loop) at Atmos. It travels south through the pipes, its first stop being the N2 Filter.
# If there was any Nitrogen in the waste gas, it would get filtered out here, and the rest of the gas continues its journey through the waste loop, same thing happening at every filter.
# The plasma finally reaches the Plasma Filter.
# Here the plasma gets extracted from the waste gas and pushed into the big plasma tank-room outside the windows.
# The plasma stays in the room until someone decides to pump it out.
# Scientist Bill by now notices that the Toxins Lab has no plasma anymore and is able to safely continue his work. Yay!


===Setting Up Atmospherics===
It's about time we stop with the theory <s>and throw it out the window</s> and get down to business. The Rapid Pipe Dispenser (found in your locker) can dispense and secure infinite pipes, and your wrench can disconnect and connect pipes to each other. There is a very old stationary [[Pipe Dispenser]] that can be found in the room as well, but it's way faster to to use the RPD.

Next up is a very simple step by step guide how to set up the Atmospherics pipe system to be (nearly) as efficient as possible. '''Despite popular belief by your neighbors the Station Engineers (and the rest of the unwashed masses in the station), Atmospherics NEEDS TO BE SET UP TO WORK WELL.''' It's similar to the [[Guide to the Supermatter|Supermatter Engine]] in a way; you could just start the emitters and it might make some power, but doing that with no setup is terrible and probably prone to blowing up.  While atmos likely isn't going to blow up, without prior adjustments it's terribly slow and very easily clogged.

Note that this is only one style how to set up the pipes, there are many ways and they all have their own pros and cons!



* '''For the love of Nanotrasen, at least do this:'''
# Select a Volume Pump in your RPD and replace the '''<span style="color:green">green circled</span>''' normal pump with a volume pump (or a valve if you are using the waste loop as a large volume mix chamber), making the waste gas -system >100x more efficient. We want the waste gas sucked from the station into the waste system as soon as possible!
# Set all '''<span style="color:red">red circled</span>''' filters ON and set them to maximum pressure (200 L/s) so waste gases will actually be moved, if they're not already maxed out.


* '''This is good as well:'''
# Go through the N2 and O2 (besides southern wall) and set their output to roughly 300 kPa. Maxing out the pumps to 4500 kPa drains all of atmos' gases way too quickly, there really isn't any reason to turn the pumps up to maximum unless you're flooding.
# Set the pumps next to the computers at 300 kPa also, so the gases being pushed out of the gas-room get moved fast too.
# Set the Air-computer's output to some amount over 300 kPa, the pumps automatically keep the gas throttled.
# Set the '''<span style="color:blue">blue circled</span>''' Air to Distribution pump to something around 800 kPa to fill up the air distribution loop. Don't max this one out, unless you want all your air to end up in the pipes (could be very annoying to filter out all of that gas if someone were to put dangerous gas in the pipes).
# If there's a thermomachine in the distribution room connected to the air pipe, it also can't hurt to heat it up a number of degrees so the station gets warm air in the event of a breach.


'''Pros and cons of this whole setup:

::'''+ Quick toxin filtering:''' In case of a toxin leak, waste gas will be sucked out quickly (if the area's air alarms are set to filter out all the toxins, that is, by default they are NOT filtering anything besides CO2).

::'''+ Quick repressurization:''' In case of a breach, air will be poured out with a nice pace, helping you re-pressurize the room quicker after the breach is fixed. The refill setting on the air alarm will also actually work with the added pressure in the distro pipe.

::'''+ Reduced pipe sabotaging:''' With this setup, its harder for the grifflords to fuck up pipes in the maintenance tunnels. In a room with the default 101.3 kPa atmospheric pressure, pipes with more than 303.9 kPa pressure fling the unwrencher in a random direction.

::'''- Air Alarm sabotages:''' The station is more vulnerable for sabotage through [[Air alarm|air alarms]]. Someone can quite easily hack an air alarm somewhere and set the vents to push out air at maximum pressure, resulting in over-pressurization.

::'''- Space wind:'''  In case of a breach, until the hole is fixed, you'll probably spend a small while fighting against the huge air current, a.k.a. "space wind", if you don't switch the vents off during the repair. This is mostly just annoying. to deal with this, find a pair of magboots.

::'''- Very slow pipe manipulating:''' If you suddenly have to modify any of the distribution pipes around the station, you need to lower the pressure to under 303.9 kPa if you don't want to be flung around like a leaf in the space wind, which can take a long time.

One extra thing to keep in mind is the fact that the thermomachines around the station dump their heat collected from cooling gasses directly into the waste loop. Common sources are the [[Cryogenics Tube|cryo tubes]] in Medical and the machines in the [[Toxins Lab|Ordnance Lab]]. Waste tends to collect only a small amount of CO2 (which is filtered back into waste) to act as a buffer to absorb said heat. With this low amount of gas, it absorbs the heat VERY poorly and suddenly the station's waste line is a couple thousand degrees. Factor in any future fires that might add hot gas to the waste line, and this means the super hot waste gas coming into atmospherics for filtering are going to take forever to make it through the pumps and filters. Not good!

To fix this, you can add more CO2 to waste to act as a buffer for heat absorption, as well as setting up some sort of cooling for waste. This can be freezers or a heat exchanger array in space connected to the waste line. This is all entirely up to you how it gets cooled, but this is merely extra setup to ensure atmospherics runs well if you have the time to do it.


Done correctly, Atmosia should be pumping good air just faster than it's lost, and draining bad air away as fast as the traitors can set it on fire or alternatively draining good air away as fast as a malf AI can siphon it. You can go kick back in the bar like a boss and wait for the inevitable minor station damage and cries of "Call the shuttle!" on the radio from folks who don't even know it ain't a big deal.

===Your Very Own Customized Mix===
To create a custom mix of gas, turn on the output of the supply control computers, open the manual valves, and turn the output of the pump to what you wish it to be. The gas will travel through the yellow pipes into the mixing chamber. The gas mix is pumped into the mixing chamber via a pump north of the yellow loop.

The mix obtained can then be pumped into the distribution and filtering loop or used to fill canisters. Remember to turn off the pump between the yellow and red pipe network or your custom mix will just go into the red waste loop.
