5 years ago Ah, yeah, you're actually right that it's a UI issue. The current code updates the mouseover every tick, and the ticks happen at a 200ms interval, so the displayed cooling is five times smaller than the actual cooling. I will try to fix this next update, thanks for the heads up.

The coolant loop is filled with petroleum which started out at 26.8°C, which is flushed around to cool 3 transformers. Each structure is placed on top of mesh/airflow tiles, and has one segment of radiant pipe, sitting in approximately 350g of petroleum, in front of a drywall. The whole area is in vacuum. No heat can be lost to the environment, since the petroleum will not conduct heat into the airflow/mesh tiles -- it is simply a medium for heat to move from the structure to the radiant pipe. There are 3 radiators.
What's interesting is that the three transformers claim to produce 3kW of heat in total, and they operate continuously, which should be steady state with 24m^2 of .9 emissivity radiator at ~-50°C according to this calculator https://space.geometrian.com/calcs/radiators.php. The screenshot below shows it having been cooled to 16.4°C

The radiators claim to only be emitting ~500W each, which is wrong for their size, and clearly they are emitting a lot more energy than that, or the whole system would rapidly be heating up.

When I reduce the whole system to a single radiator and let it run for a long time, it seems to just continue getting colder and colder, certainly well below the ~20°C that 8 m^2 of radiator should run at.
