Good guide for Thermo Regulator-based hydrogen cooling?

[Xiphoris]

Is there a good guide online for setting up effective closed-loop electricity-based hydrogen cooling using thermoregulators?

To test the theory that thermoregulators can destoy heat, in a debug mode game, I created a small room (4x4 tiles) filled with about 2000g or 1000g of hydrogen at 50C. I pumped the hydrogen through a thermoregulator and then back into the room. When I did this, I gradually noticed the room cooling down from 50C down to 40C and lower. This demonstrates that thermoregulators can destoy heat.

EDIT: I'm no longer sure whether thermoregulators destroy heat after more experiments. My previous experiments may have not been closed systems. I was using rooms containing tempshift plates, which I believe were altering the resulting temperature because of their own mass.

What's the trick for cooling closed-loop hydrogen down to low temperatures like 0C or below? Do I just need to wait a long time, or is there any trick to speed things up? I tried running multiple thermoregulators in series - while the hydrogen coming out was really cool, it didn't seem to have a noticeable effect on the speed of cooling the room overall.

Additionally, does anyone understand why this happens? If thermoregulators truly lower the temperature of the gas that passes through them by a fixed amount (Kelvin), then I would expect the cooling effect to be independent of temperature. Instead it seems like the temperature levels off. The same is also true for a room with just wheezeworts: it quickly cools down from 50C to 40C, but cools much more slowly after that.

Is there a way to build an effective cooling system using just thermoregulators or do I need to use other techniques like AETNs?

On the other hand, should I really care if this is the case? I was originally planning to try to cool down the entire room to a low temperature, but maybe I should just ignore the room's temperature, and instead directly use the hydrogen coming off the thermoregulators to deliver cooling to the places where I need it. If thermoregulator-based cooling becomes more effective at high temperatures, then maybe it's OK if the room warms up, as long as the thermoregulator / wheeze can keep it under control.

I can't get a picture because I'm on my phone during vacation. But my setup has four thermal regulators in a room full of hydrogen and a wheezewort in the middle. And it can run stable while active 100% of the time.

I use it to quickly cool O2 from an elecrolizer down to freezing.

It takes a lot of power to run though.

Below is an early setup I used for cooling my base. It still exists, but for another purpose, cooling down plants, to counteract hot water effects, until I'm not so lazy and build a proper AETN water temperature management system.

The first image is the regulator room, which is frozen due to low temperatures. The second is the pipe leading to the bristle blossom area. The third is the temperature overlay, showing the effect. It's very cold, and this is oxygen; hydrogen would certainly drop temperatures much further.

This pipe did run directly through the oxygen release vents, which naturally cools all of your base, since the cooled down oxygen will travel.

If you have no opposing heat force, your temperatures should continue to drop as a result of the cold you're introducing into the environment.

This is another current experiment in oxygen cooling, for breathing, no loop here.

This oxygen arrives from electrolyzers, and leaves the room at about 0-7C. These pipes pass by transformers, which cool down the transformer heat and elevate the cooled oxygen temperatures to tolerable levels before arriving at the base core.

After further experiments, I now believe that thermoregulators do not destroy heat. At least, after further experimentation, I cannot demonstrate them removing heat from an environment consistently. I would need to set up more precise experiments in order to measure the effect convincingly if there is one. If they do destroy heat, it's not in a strong or obvious way like wheezeworts.

I previously drew this conclusion because I saw the room cool down containing my closed system, but now I think it may have been tempshift plates that were in the room cooling it with their own mass. I can't reproduce the apparent cooling effect in a room without tempshift plates.

Additionally, my room was cooling very slowly because it had a large number of tempshift plates, which have a lot of mass. I wasn't accounting for that previously. The apparent gradual cooling that I witnessed, which tapered off to an equilibrium, was simply (I now believe) temperature equalizing within the room. (I'm not completely certain though and have not run subsequent experiments to tell for sure.)

Thus at the moment, I think a hydrogen cooling room requires wheezeworts to work, and the cooling comes from wheezeworts; the thermoregulators are purely exchanging heat from once substance to another.

Wheezworts are magic. The sad frustrating reality is they are designing all the buildings to not work at the effiency we want them to unless built in conjunction with multiple other systems and designs. Frequently involving other biomes and other complexities.

The expansive guides in play at this time, many have caviats that they no longer work as intended.

You have to think 3 builds ahead, and 4 systems deep to get a handle on it. Whatever you are going for.

And should an update change any of the values on any of it, it's back to square one.
