{{Info|A '''vent''' allows transfer of [[temperature]] and [[gas]]es from one room to another.}}

== Acquisition ==
Vents can be constructed once the [[Research#{{P|Required Research}}|{{P|Required Research}}]] research project has been completed. Each requires {{Required Resources}}, {{Ticks|{{P|Work To Make}}}} of work, and a [[{{P|Skill 1}}]] skill of {{P|Skill 1 Level}}. Placement of a vent requires pathable space on either side - furniture such as [[stool]]s will not impede function, but a [[wall]] would.

The blueprint can be laid atop an existing wall; the wall is replaced upon construction. 

== Summary ==
{{Stub|section=1|reason=1) Gas spread mechanics 2) Hard numbers for temperature transfer in both open and closed states}}
Vents act structurally like a wall, preventing movement, enclosing a [[room]], and supporting a [[roof]]. They have two states - open and closed. In the open state, they allow the transfer of [[temperature]] and [[gas]] from one room to another at their full rate.{{Check Tag|What rate?}} Even when open, vents are not 100% efficient at equalizing temperatures between rooms.{{Check Tag|Quantify}} When closed, the transfer of temperature is reduced{{Check Tag|What rate?}}{{Check Tag|Same as normal wall?}} and the transfer of gas is ceased entirely. The vent can be designated for opening or closing by the player, which will then be actioned by a pawn assigned to [[Work#Basic|Basic]] work.

As with walls, the transfer rate is directly proportional to the number of tiles however temperature equalization itself is non-linear. Thus, more vents will decrease the time to reach stability.

A vent cannot be uninstalled, only deconstructed, at the usual loss of half the material.

== Analysis ==
{{Stub|section=1|reason=Needs thermal transfer rate analysis vs walls, double walls, closed doors and open doors}}

General tip: As efficiency is lost for every vent, minimising the number of vents between source and destination is ideal. heat or cool one central room

== Version history ==
* [[Version/0.17.1546|0.17.1546]] - Vents can now be opened and closed with a simple flick action.
* [[Version/1.4.3555|1.4.3555]] - Gases can now travel through vents.
