- Removed legacy dependencies
- Fixed the issue with the game crashing when having very large pipe-networks. Fix done by luoluo38!


Centralized Air Cooling/Heating System for RimWorld. Build Large Piped Air Climate Systems away from your buildings.


This mod is no longer maintained. Due to recent life changes, It is hard to find time for this mod. The license has been modified to MIT License so people have been given freedom to modify the mod itself. Overall, the mod still works fine, there may be incompatibilities with other mods that I would not have discovered. I highly recommend looking at the Getting Started guide on steam if you are trying it out.


Rimworld Version: 1.0.0 (Check Github releases for older versions)
Version: 1.5.0

Watch this video if you are having issues with the guides. It’s a little old, but covers the basic usage of the mod!

While there are many alternate mods for Central Heating. This mod adds a new network-like resource (like electricity) Air. The heating/cooling system you will build depends on the number of rooms and the heating/cooling capacity of your air networks.

There are 3 colored pipes available. All can carry any type of air.

Following buildings are added:
- Air Intake Fan: Fans to supply air to the system
- Air Climate Control System: Heat or Cool air to a target temperature
- Air Vents: Vent out the heated/cooled air
- Wall Mounted Air Vents
- Large Intakes and Air Climate Units

Features and Differences (from other mods):

Unified Heating/Cooling System
Heating and Cooling is done by 1 unit, so reduces the need to build coolers and heaters.

Outside (and Far away) Heat Exhaust:
The Heat Exhaust of the Climate Control units isn’t located adjacent to rooms. They are located far away from your rooms, thus allowing you to make adjacent rooms to fridge rooms.

Air Network
There is a network-like resource (like electricity) which is generated and consumed which is further dictated by Efficiency of the Network.
1) Flow Efficiency
The rate at which your rooms will cool/heat or maintain heat due to changes in the room temps.
Value: 1 Intake Fan for 3 Rooms

2) Thermal Efficiency
The rate at which your Climate Control units can heat the air. Sudden changes like Cold Snaps or Heat wave will inject very cold or very hot air into your system. Climate Control Units will take care that, but their rate is determined by this Efficiency unit.
Value: 1 Climate Control Unit for 3 Intake Fan

You can always check efficiency of each network at the Vents.

Air Temperature inside Pipes
This mod also deals with the temperature of the air in the Pipe Network.

Can share air without Climate Control units
Intakes take note of the Air Temperature the take in. We can practically make Climate Control-less networks that share the same temperature.
For example:
Multiple Frigdes can be connected together, but only 1 is getting the cooling. The rest just share the air.

Bigger buildings for late game
Build larger Intakes and Climate Units which have about 5x more power than a regular machine.

Pipe Switches
If you have multiple pipes near your vent, You can force it to connect to a specific pipe.

1) Make sure you enable HugsLib first and before this Mod
2) Enable the Mod in the Mod List

Known Issues:
- Compatibility Issues with Redist.Heat Mod
- Reinstall doesn’t work properly (Install and Uninstall works fine.)

This is my first mod for any game ever. There might be some issues. I wanted to see how the community responds to my mod, and want to work more on it! :)

Thanks if you are trying my mod out!

just a lazy idea

@cjoysarkar Yes, you need to have done the required research

Bro do i need to research something for it to show up? I dont see it in my temperature tab in the new game. may be i'm being dumb and missing something?

Mlie the legend does it again, im just coming back for the new dlc and seeing youre still actively updating old outdated mods and some of my favorites among that brings me great joy!

@AerosAtar Should be fixed now, sorry about that

[1.5] I seem to have lost the ability to see/toggle the pipe network visibility overlay. Not sure if this is just a bug in the mod or a conflict with something, but thought it was worth mentioning in case it is something that needs tweaking for 1.5.

Amazing mod update, but I can't see the air flow temperature inside pipes.. With UI temperature overlay on, or by even clicking on a piece of pipe to inspect as you would do with power conduit. Not sure if I am doing something wrong?

The issue with game-crashing with large pipe-networks should now be fixed. All work done by luoluo38!
luoluo38 Jan 21 @ 4:05am 
Certainly! however, I need to do more testing to ensure that no bugs were introduced.

@luoluo38 Great find, can you do a PR to the Github repo with your changes perhaps?

I rewrote this function with iteration, and the game no longer crashes when the network is too large. but it will still take for a relatively long time (a few seconds)
