Electric cooling

[Gurgel]

While we have electric heat pumping, we do not have electric heat destruction. Yes, sure, real-world physics does not have that, but it is already in the game via the nullifiers and the WWs. The problem is, you do not have enough for a large base and you may have to euthanize dupes if you estimated wrong and created too many if you aim for long-term sustainability. This strikes me as wrong. Hence I would like so see some heat destructor that can be built and that is driven by electricity and has a reasonable efficiency that a dupe on a hamster wheel can generate all the cooling needed for this dupe to survive, taking into account some overhead for food production and toilet-breaks and some other work.

If you were in the game just as imaginative as you are in suggestions, maybe you could have see how bad your suggestion is. There are already many possibilities to get rid of the heat from the base, use them.

[Smuch]

A lot of way to get rid of heat now as far as I can tell use either gitches (the drip thing) or some fairly rare resources (the wheeze wort and enthopy nullifier aren't exactly all that common). Sure I fully expect that as the game get updted more ways to del wih heat wil appear (icluding eventualy 'radiate it into space') but in the meantime It would be nice to have some earlier heat sinks options a least

Currently the only ways to destroy heat in the game are to:

1. Use AETN or wheezeworts to directly remove it. Rather rare resources, but fairly easy to use.
2. Exploit the fixed outputs of certain buildings such as NG generators or water sieves.
3. Exploit the difference between thermal capacity of H2O and pH2O, and boiling pH2O loses significant thermal mass when converted into steam.
4. Use steam turbine to turn heat into power. Only works at 300^oC or higher.

Most of these are not even remotely realistic, and only option 1 is intuitive. There does need to be some means to concentrate or harness thermal energy in the game, as all of these methods simply destroy heat, except for steam turbines.

OP's suggestion is bad yes.

But the concept of electrically powered heat-pumps is good, https://en.wikipedia.org/wiki/Thermoelectric_cooling is a good thing and something we could easily have in game.  I imagine it being a 1 tile thick wall tile which has a direction arrow like a planter, when powered it moves heat from one side to the other.  Such a device can also work in reverse to generate electricity from a heat difference.  They are less efficient then other heat-pump of heat-engines (like the steam turbine) but they are simpler and easier to place.

CU is out just vent the excess chorline to space!

well all we need is AC , air conditioners !!!!!!

Actually, we already have them. Google for "heat pump". Check in game: Utilities/Thermo Regulator - it's AC outdoor unit.

We are asking for indoor units which we dont have for now.

For what? What functionality should it serve?
I know the right answer, but I wanna see your point.

[he77789]

Cool the environment and heat up the pipe. We can make environment hotter than pipe using energy, but even radiant pipes will only as much as average the temperature, so we cannot make pipe hotter than environment using energy. What we want is a machine that fills this gap.

Yes. You could pump the material in the environment into pipe and release the piped material, then after cooling do the reverse, but it will cost 480W more for the pumps. Either we need a machine to put material into pipes without energy, or we need the AC indoor unit.

First things first, we should mention that it's not an important/ASAP type of game improvements. Current the most valuable design is a centralized HVAC system, because we need to pump-in oxygen anyway. The solution is pumping oxygen through a chain of Thermo Regulators with automatically controlled bypass valves that depend on indoor temperature. No additional energy cost for pumping.

Talking about heat pumps, we should take into account that they consist of two main blocks or heat exchangers: a condenser (heat output) and an evaporator (heat input). (As well there are an expansion valve and a compressor between them, but it's off topic.) The problem is that the Thermo Regulator actually is both indoor and outdoor unit in one device. It pumps gases through built-in evaporator, takes heat from them, and outputs heat via built-in condenser. To make absolutely legit AC split system, we need to literally split Thermo Regulator in two separated parts connected via one gas pipe and one liquid pipe. That's all about the theory.

I partially agree with you. Something like an AC indoor unit can be useful. Something that corresponds outdoor unit (-14 K) and adds 14 K to pumped gas, like reversed outdoor unit. It's not legit split system, it's more like two independent heat pumps, but it's ok for a game. Plus forced downward air circulation. Plus positive effect on decor. And reversed versions for the water heat pump (Thermo Aquatuner).

And partially disagree. Because it's all about Δt°. If you cool down a coolant to -200 °С (possible for hydrogen, controllable via pipe sensor), the system based on radiant pipes would be a way more effective than "indoor unit" that just adds 14 K. Therefore usefulness of the indoor unit solution is limited to environment where you can't achieve high values of Δt° for some reasons.

Cooling down to -200c is very hard if possible for newbs. Did you even got exosuits on your first run after buying ONI, before you read the forums?

In what universe this is considered to be very hard?

[he77789]

What? I mean in your first run, you are very lucky to get the regulators and pipe variants and find aetn without reading the forums. A game should not rely on tutorials in forums.

[SkySentinel]

The game relies on your basic knowledge of Physics. If you don't have it, you're doomed without guides. The game is supposed to be like that.

P.S.: AETN is optional, some WWs will be enough: 2.4 J/g/K * 1000 g * 14 K = 33.6 kJ/s or 33.6 kW per one heat pump with hydrogen as a coolant.

[he77789]

What about research? Sucessfully research the required tech in the first run is already a feat. Accounting the time to get the materials, good luck surviving that long on your first run.

[SkySentinel]

How does this in-game challenge relate to adding new heat management devices? You need research and resources anyway. And by the way, all of the needed resources (wolframite, abyssalite, wheezeworts) can be found in a cold biome.

Mhh.

Also to refine them.

 thermal regulators on a valve set to 300g/s after a 1 pump intake will never over heat no matter how many ac units you use.(pump-> regulator ->valve) so if you wana dump electric power to cool go ahead we have allways had ways. hell 14 ac units in series will burn 196c off your gas cost the power of 7 and still never over heat. the regulator will burn energy and create heat every time the gas moves along the pipe the valve slows that rate down to about half its through put but spreads out the heat and consumption across the system.having the loop back on regulators only makes them work harder for a small load when you can accept that the small load is still your outcome you adjust and make the though put smaller remove the loop and save your energy and heat.
