Guide to Atmospherics

Atmospherics. To the ignorant, a mystical art indecipherable from actual magic. To the (hopefully) educated Atmospheric Technicians of the station, a glorified network of conveyors for moving gases about. Either way, Atmospherics holds great and terrifying power in the hands of the initiated.

Pipes and Gases, the Basics of Atmos

If you aren't working with pipes and gases, you aren't doing atmospherics.

Where to get Pipes

Meet your two new friends. One never returns the money they borrow, you aren't really sure why you hang out with them. The other one is kind of awesome.

Pipe Dispenser - A static machine that will print out pipes for you.

Rapid Pipe Dispenser - A hand held tool that can print, place and recycle pipes for you. Fits in your backpack and doesn't need ammo.

Beneath are all the things your dispenser can make. Learn them well, for they are the fabric from which atmos is woven.

Types of Atmospheric Pipes

Items	Name	Description	Details
	Atmospheric Pipes	Generic Pipes that can be used for most tasks	These are airtight pipes that can carry any gas you pump into them.
	Air Supply Pipe	Used to distribute air all across the station.	Special pipes that are needed to connect to vents. Standard unaltered atmos uses these for air distribution
	Scrubber Pipe	used to move waste or harmful gases.	Special Pipes that are needed to connect to scrubbers. Standard unaltered atmos uses these for taking in and processing harmful gases like CO2.
	Heat Exchange Pipe	Imparts some of the enviroments temperature to it's contents.	Allow you to cool / heat gases based on the ambient temperature of the tile they're on. Think space loop (for cooling) or the Toxins burn chamber (for heating)
	Universal Pipe Adapter	Can be fitted to any other pipe type.	Used to bridge between Atmospheric, Scrubber and Supply pipes. Atmospheric, Scrubber and Supply pipes cannot connect to eachother without this.

Types of Atmospheric Devices

Items	Name	Description	Details
	Unary Vent	The standard vent used to distribute air.	Needs to be inside a blueprinted room with a functional air alarm to operate. Typically used to pump breathable air into a room.
	Passive Vent	An unpowered vent that relies on pipe pressure to operate.	Will only release it's contents if the pressure of the room it is in is lower than the pressure of the pipes it is hooked up to.
	Dual-Port Air Vent		Has a valve and pump attached to it. There are two ports.
	Air Scrubber	Scrubs the air clean.	Needs to be inside a blueprinted room with a functional air alarm to operate. Used to remove specific gasses from the room it is in. Normally used to remove harmful gases like CO2 from the station's air.
	Connector Port	A connection port for tanks of gas	Allows you to remove/add gases into a system directly from a tank. Simply place the tank on the connector and wrench it in place. After it is connected, open it if you want to pump gases out of it. Actually pumping the gases in or out of a connected tank only requires you to set up a pump.
	Gas Pump	A Generic Pressure Pump	This Pump is configured to measure how much gas it pumps by pressure. Can be set to only pump a certain amount of pressure through. The maximum pressure this pump can be set to move is 4500 kPa
	Volume Pump	The Gas Pump's cool sibling	This Pump is configured to measure how much gas it pumps by volume instead of pressure. Can be set to pump only a specific volume of gas through. The maximum volume this pump can be set to move is 200L/s.
	Passive Gate	Basically, a pressure valve	A valve that only lets gas through if it the input pressure reaches a certain threshold. Can be set to activate anywhere between 0 and 4500 kPa. It should be noted that its power status light can be easy to miss, being just a small red / green light, and can be used along side a passive vent in place of a Unary Vent.
	Gas Filter	Separates out gases	A Scrubber in pipe form. Checks for whatever gas you set it to, then filters it out into another pipe.
	Gas Mixer	Mixes Gases together	The opposite of a filter. Takes the contents of it's two inputs and combines them together at whatever ratio you tell it to, then pumps them through the output. Importantly, ratios are measured by pressure, not volume. Maximum output pressure is 4500 kPa
	Air Injector	Used to force gases into high pressure areas.	A gas injector that will continue to pump it's contents out regardless of how high the pressure around it is, Measures how much it pumps by volume. Will not operate without being linked to a console. Will display a green light when on.
	Manual Valve	A simple hand turned gas valve.	A manually-controlled valve, it requires no power and also no ID authorisation to use. Is arguably better over the digital valve in pipe-networks with possibilities of massive destruction due to the need of ID access on the digital valve. Displays a small green light when open.
	Digital Valve	An electronic valve.	An electronically-controlled gas valve. It uses the station-grid's power to be operated but requires sufficient ID access to be allowed use. Can be operated remotely by the AI, and by crew if they have the right tools to access it. Displays a small green light when open.
	Meter	Measures temperature and pressure inside the pipe it's on.	Simply place over any flat stretch of pipe and wrench it on. Upon examination, it should now be yielding measurements on what is going on inside the pipe. Does not provide as much information as an analyser, but good for being able to tell what is going on at a glance.
	Gas Sensor	Senses Gas. No. Really.	Used to sense the pressure and temperature of the gas surrounding the sensor itself, rather than a pipe. Can be hooked up consoles.

Types of Disposal Pipe

Items	Name	Description
	Disposal Pipe	Those pipes are made through the disposal pipe dispenser, use them to fix or expand to the disposal system of the Exodus.
	Disposal Bin	Where people put their trash which are then sent to the disposal area via the disposal pipe system.
	Disposal Outlet	Whenever someone or something has reached this from a disposal pipe, they are thrown out at quite a fair speed and typically end up hitting a wall before stopping.
	Disposal Intake	If something's been thrown into the intake, it will take it and put it into the attached disposal pipe, sending it off on it's merry way.

The Gases

The main goal of atmospherics is to manipulate these in a way that benefits the station. Each type of Gas has different properties that can help or hinder. Your skill in manipulating these will determine the success of your atmospheric machinations.

Nitrogen (N2)	One of the components of the air mix. N2 soaks up heat in the air, and lowers the temperature of a fire. By association, it can very quickly lower the temperature of a fiery rupture to the point where the flames self-extinguish.
Oxygen (O2)	You probably breathe this. Running out of O2 will cause your slow death by suffocation damage. It is also required for a fire to even start, with the ending the fire when the O2 or plasma (if present) is depleted. Having less than 17 kPa of O2 flowing into your lungs chokes you.
Air	The gas mix that is distributed in the station. It is composed of 80% N2 and 20% O2.
CO2	An invisible, heavy gas, CO2 is one of the first and fastest gases the scrubbers suck out of the air. It chokes people effectively and quickly, and if you can be bothered to set the air alarms up, will result in a invisible room that kills those in it. Takes some setup and can be very, very annoying. The emote for this at below incapacitating levels is gasping and choking.
Nitrous Oxide (N2O)	A white-flecked gas. Makes you laugh at low doses and at higher ones puts you to sleep. Scrubbers don't deal with it too well and portable scrubbers just choke on it. If using this as a sleep gas mix do *not* forget the O2 at at least 17 kPa, or you will kill someone. Relativly high in density at room temperature.
Plasma	The oil of the new world. Purple, highly flamable, and highly toxic ("Toxins" and "Plasma" are occasionally used interchangably). Burns hotter as oxygen is added. Can spontainiously ignite if at high pressure with oxygen. The highest density gas at room temperature.

Station Systems

While pipes themselves will always work if undamaged, atmospheric devices all have certain prerequisites that must be met for them to operate.

Remember, ALL Atmos Devices require a powered APC to work.

In addition, there are other pieces of infrastructure that can/must be used when working with specific atmospheric devices.

Air Alarm

Mandatory for the use of non-passive vents and scrubbers. Allows a wide range of control over a blueprinted rooms current gas contents. Where exactly the Air Alarm is in the room does not matter; As long as the room is blueprinted and powered it will function. Cannot be placed in areas that are not blueprinted.

Computers Consoles

• Atmospheric Alert Computer: This computer console will tell you where your attention is needed. Green means everything is alright, yellow signals something is wrong, and red means things have gone wrong enough for an alarm to be triggered (Usually caused when a room's air stops being breathable).

• Central Atmospherics Computer: Allows remote control of any air alarm on the station that has remote access enabled.

• The Distribution Computers: A console to monitor gas storage contents, control air injectors/extraction vents, etc. If you understand how to use these properly, you probably know what you are doing. Air Injectors REQUIRE these to work.

Atmosia Proper - The beating heart of the Station

Left - Atmosia with non-air systems faded out; Right - Simplified diagram of the Air Processing System in Atmosia

In Atmosia, you will see many different colored pipes. These colors are labels, marking out different systems within atmosia.

Name	Description
Air Supply	The dark blue pipe is the Main Air Supply. It sends breathable air (roughly 80% nitrogen and 20% oxygen) to all the vents on the station, and is fed by the cyan pipe in Atmospherics.
Scrubber	The red pipe is the Scrubber Pipe. This is where all the toxic waste normally ends up by the scrubber system found all around the station. It may contain breathable air, however it is unfiltered and possibly contaminated.
Air Mix	The cyan pipe is the breathable air or the Air Mix. This pipe feeds into the main air supply.
Waste	The purple pipe is the Waste Pipe, which retrieves waste air from the scrubber pipe which then leads to the filter.
Filter	The green pipe is the Filter Pipe, which filters out the various gases in the waste air provided by the water at various filters placed along it. Each filter puts the respect gases back into the gas containers.
Pure	The yellow pipe is the Mix Pipe, which is internal to Atmospherics and is used for custom air mixes.

The Basic Mathmatical Details

Ideal Gas Law

The magical formula for improving your burn mixes.... and explaining why your coolant pipes have such a low pressure.

Formula: PV=nRT

P - Pressure in kilopascals or kPa
V - Volume in liters
n - is the amount of substance of gas (also known as number of moles)
R - is a constant or 8.31
T - Temperature in Kelvin

Cooling a gas will make it take up less space (volume) for each unit (mole) of said gas. This effect also results in a gas at a lower temperature having a lower pressure. Heating a gas will have the opposite effect, resulting in a larger volume and higher pressure per mole.

Conversion to and from Kelvin

While most things will yield temperature in both Kelvin and Celsius, here is the conversion formula just in case.

Formula: K = C + 273.15

C - Celsius
K - Kelvin

(Temperature in Kelvin minus 273.15 is that same temperature, but in Celsius)
