Proper room cooling. Air Conditioning brings a real split air conditioner: indoor unit on the wall, outdoor unit outside, connected by a refrigerant pipe. On top of that come air conditioners in three sizes that work like the game's air conditioner with input, output and waste. Since 1.2.0 heating and ventilation are part of it too. All devices have custom 3D models, displays, LEDs, spinning fans and full IC10 control.
Split air conditioner
- Indoor unit on the wall, three cells wide. It exchanges up to 25 kW between room air and refrigerant, has three fan speeds and a thermostat on the room temperature (default 21 °C). In AUTO mode it also heats.
- Outdoor unit on the ground or on a frame, 2 × 1 cells. It keeps the refrigerant at 5 °C and releases up to 220 kW to the outside air, for at most 5.5 kW of power. The game's air conditioner manages up to 14 kW with about 0.4 kW.
- Connected by a gas pipe network filled with a gas, ideally nitrogen at 500 to 2000 kPa. Several indoor units may share one network.
- The outdoor unit needs an outside atmosphere of at least 6.3 kPa. On hot planets its output drops.
Air conditioners 3, 6 and 12 kW
- Input, output and waste like the game's air conditioner, but with a display and much stronger: up to 125, 250 and 500 kW moved, 8000, 16000 and 32000 L of gas per tick – more per kW of power than the game's air conditioner.
- AUTO mode as in the game, or fixed COOL.
Heating & ventilation
- Wall heater with blower: 2, 4 or 6 kW with a thermostat, blows the warm air visibly into the room, FAN mode with the blower only.
- Flow wind wheel: shows the game's real air flow, free-spinning or with a generator up to 100 W.
- Chute-sized ventilation ducts with duct grille and duct fan, a duct network of their own that moves air from room to room.
The displays have at most four lines and a page number, page 1 shows the most important values in large text. The floor-standing devices carry display and buttons on a sloped desk. All kits come from the hydraulic pipe bender, tier 1. Labels, displays and device names appear in German or English, depending on the game language. The server and all players need the mod. For single pipes there is the Pipe Cooler.

Version history
-
v1.2.0Oct 14, 2026
Heating & ventilation: wall heater with blower (2, 4 or 6 kW, thermostat, FAN mode), flow wind wheel free-spinning or with a generator up to 100 W and chute-sized ventilation ducts with duct grille and duct fan in a duct network of their own. New console commands klima luft and klima kanal. Existing devices and saves are unchanged.
-
v1.1.1Oct 13, 2026
The refrigerant pipe runs flush into a socket on the indoor unit, power and data connections sit on the wall plane.
-
v1.1.0Oct 9, 2026
Air conditioners 3/6/12 kW much stronger: up to 125/250/500 kW moved instead of 12/25/50 kW and ten times the gas per tick (8000/16000/32000 L). They now cool more per kW of power than the game air conditioner. Custom settings are kept, old default values are raised automatically.
-
v1.0.0Oct 8, 2026
First release: split air conditioner made of indoor and outdoor unit with refrigerant pipe and heating in AUTO mode, plus air conditioners rated at 3, 6 and 12 kW. All with custom models, displays, IC10 and the console command klima.
Frequently asked
What do I fill the refrigerant pipe of the split air conditioner with?
With a gas, ideally nitrogen at 500 to 2000 kPa. Any other gas works too. More gas and more pipe buffer better. Use insulated pipe outside, otherwise the sun heats the line. Several indoor units may share one pipe network.
The outdoor unit shows NO AIR and does not cool.
It releases the heat to the outside air and needs an outside atmosphere of at least 6.3 kPa (Armstrong limit) for that. In vacuum this does not work. There the air conditioners 3, 6 and 12 kW help: they release the heat into the waste pipe. More in the guide.
Why doesn't my flow wind wheel turn in a closed room?
At equal pressure the air is still. The wheel shows the game's real air flow. It turns in front of a blower (wall heater, duct fan, duct grille), at an open airlock, at a vent or outside in the wind. klima luft shows the value at your position. More in the guide.
Can I connect ventilation ducts to normal gas pipes?
No, on purpose. Ducts form their own network and connect only to ducts, duct grilles and duct fans. Game pipes do not fit into a duct cell. A duct fan at one duct end moves air from room to room, at the other end it comes out of a duct grille.
