The Active Vent moves gas between the connected Pipe Network and the surrounding atmosphere. It requires electric power to work (100 Watt). Its functionality depends on the selected mode:
- In "Outward mode" (switch in blue), it increases the external pressure by moving gas from the pipe network to the surrounding atmosphere, up to "PressureExternal", by default(*) equal to 101 kPa
- In "Inward mode" (switch in red), it decreases the external pressure by moving gas from the surrounding atmosphere to the pipe network, down to "PressureExternal", by default(*) equal to 0 kPa
The "PressureExternal" and "PressureInternal" values can be modified using logic chips or programmatically via IC10 scripts.
Note: These values reset to default values on mode change. Values can be set through logic chips, if the value is modified after a mode change.
Note: Switching logic chips off then on will not modify values on the active vent, the values supplied to the chips must be altered for the values to be written.
(*) This is the reason why airlocks need an internal pressure of at least 100 kPa to work correctly. This behavior can also be inconvenient on worlds like Loulan whose atmosphere is well above 101kPa. Manually-operated "airlocks" for greenhouses can not pump back up to Loulan atmosphere during the exit cycle. If the pressure is already >101kPa the vent will have no effect, and if it is <101kPa the vent will stop when it reaches 101kPa.
To calculate the moles per tick, use the following equation:
n = (P * V) / (R * T)
Where (Inward vent):
- P = Min(Room pressure, 10.1325 kPa)
- V = 8000 litres
- n = Moles per tick
- R = Gas constant (8.3144)
- T = Room temperature
Where (Outward vent):
- P = Min(Pipe pressure, 10.1325 kPa)
- V = Pipe volume in litres
- n = Moles per tick
- R = Gas constant (8.3144)
- T = Pipe temperature
(These do not take into account the constraints imposed by "PressureExternal" and "PressureInternal")
Note: In order to get the proper units out of this calculation you need to use either kilopascal (kPa) and litre (l), or Pascal (Pa) and cubic meters (m3).
Note: The insert slot currently takes any item and seems to have no effect.
Data Network Properties
These are all Data Network properties of this device.
These lists the values and meanings for the "Mode" property of the Active Vent.
|0||"Outward" mode (Moves gas from the connected pipe network to the surrounding atmosphere.)|
|1||"Inward" mode (Moves gas from the surrounding atmosphere to the connected pipe network.)|
These are all parameters, that can be written to with a Logic Writer, Batch Writer, or Integrated Circuit (IC10). The outputs are listed in the order a Logic Writer's "VAR" setting cycles through them.
|Parameter Name||Data Type||Description|
|Open||Boolean||Does not function.|
|Mode||Integer||Set the Active Vent mode. (See Mode Values)|
|PressureExternal||Float|| "Outward" mode: Maximum pressure of the surrounding atmosphere. The default value is 101.325 (kPa).|
"Inward" mode: Minimum pressure of the surrounding atmosphere. The default value is 0 (kPa).
|PressureInternal||Float|| "Outward" mode: Minimum pipe network pressure. The default value is 0 (kPa).|
"Inward" mode: Maximum pipe network pressure. The default value is 50662.5 (kPa).
|Lock||Boolean||Lock the Active Vent when set to 1. Manual operation is not possible while locked.|
|Setting||Float||Does not function.|
|On||Boolean||Turn on the Active Vent when set to 1.|
Note: The value of "PressureExternal" and "PressureInternal" will be reset to the default when changing modes.
Note: If turned on, the vent will still consume energy when the target pressure is reached.
