Cooling efficiency and working temperature of wheezeworts?

Pumping and using 65 C water through my base and for all my machines will cook the poor dupes and gradually heat up the whole base until it is uninhabitable.

ok, well. I'll show you some thing in couple minutes - ok? just wait, hehehe

I think I've heard it mentioned that machines and objects that input a material like water are apparently unaffected by the water's temperature. So as long as the water flows through abyssalite insulated pipes throughout your base, even if 90 C water goes to your farm tiles or hydrolyzers, the output temperature will be unaffected? But that seems like it must be a bug or oversight to me.

Nice video, that demonstrates what I thought above. However I think that must be a bug or oversight because it seems silly to me you could feed 2000 degree magma to a machine and not heat up the surroundings. :p

Absllyte pipes my friend, absyllte pipes. Then wheezeworts in the base proper.

QuantumPion here you go, tell me is it help you? 

 

Nativel belive me it's very stupid to poke fun at people with video title I can imagine, believe me. This sentence will free you from this hard job.

@Nativel From the video, i have some questions.

1. How did you make all refrigerators could store foods evenly? With more than one, i had always uneven distributions and some empty storages.

2. When dupes showering, don't they hurt or aren't stressed by hot water?

but it's realy true, cose I know how it's hard and if you fill fun and you think you poke some one by this title it's not mean I feel the same, cose I'm not you.

here is the screen where I belive you will see that I know how it's hard....

I can't explain it w/o video, so... it's because some of them not eat all food from the fridge.

All fine. They fill happiness.

I see nothing in that video that couldn't be explained in a paragraph of text. Use abyssalite pipes, then the hot water won't heat your base up. And dupes are fine showering in scorching water. Here, done.

Video was about how food go in the fridges.

Dupes don't care what temperature of water will be in the shower, they care only about gases/liquids/tiles temperature they step.

Normal pipes made from abyssalite should currently do, havn't seen them change temperature in any form that is relevant for a colony <1k cycles... BTW: I suggested to cut the cost of the insulated pipes down to the normal ones but make them buildable from abyssalite only - would lead to the same amount of material used in isolated ones as of now, just rid us of the scrolling in the material selection window.

Not really related, but I find the concept amusing of Dupes trying to work with a material like Abyssalite.  How would you easily mold or shape a material that you can't thermally change?  They must be chiseling away at the stuff like cavemen trying to shape it into pipes :D

Perhaps it's malleable.

Ahem...  So what is the point of insulated pipes then? :D

A bit of a necro, but I think I solved the mystery of my experimental results.

I noticed that the temperature reduction was extremely well-correlated with:

specific heat capacity / thermal conductivity

I couldn't figure out why for a long time, but then I noticed that the Wheezewort itself is 400kg (!!). In my experiment I believe it started out at 293K in all cells, so the gas would quickly cool to a point where it would gain heat from the Wheezewort's mass. So basically what I was seeing was that, in a particular instance of cooling, it follows the game code: higher specific heat means higher wattage of cooling. However, the thermal conductivity of the gas affects how much heat it transfers with the Wheezwort's own mass.

The reason why the ratio between the two is the key characteristic for temperature is because thermal conductivity determines how much energy gets absorbed, and specific heat governs how much temperature change results from that energy.  So Natural Gas had the highest temperature change because it didn't absorb much heat from the Wheezewort, and what little heat it did absorb didn't change its temperature as much. Compare to Chlorine, which had much lower conductivity, but also much lower specific heat; so although it absorbed less energy, the energy it did absorb changed its temperature more. Hydrogen suffered the most from this in terms of my calculated wattage because it has the highest conductivity, so it absorbed much more heat from the Wheezewort mass.

However, in terms of actual wattage of cooling, Hydrogen is the best, and we can safely use the calculations given from the game code now that we understand the experimental discrepancy. So Wheezeworts cool Hydrogen at 12 kW, and have exactly 5/14 the effect of a Thermo Regulator, without heat output in the area.

Natural Gas, while it looked good, actually has only 10.96 kW of cooling, and is much less effective (20.8% of Hydrogen) at absorbing other bodies' heat.

TL;DR: Use Hydrogen with Wheezeworts; Natural Gas might look good in short experiments, but its success is a lie.

Perhaps Abyssalite is a ceramic. Ceramics can be shaped before they are fired into their final form, and have many of the properties of Abyssalite.

That was their inspiration for it.

Yes, but abyssalite is also hardest mineral in the game that's currently spawned with a hardness of 200, in comparison, Granite is just 80 and diamond which you can spawn in using the cell painter, is 250.

That doesn't sound terribly malleable to me. :D  That's not to say we shouldn't be able to use it for making stuff.  It definitely fills a gameplay role in ONI.  I just find it an amusing concept that Dupes can create tiles and pipes with something that's effectively close to diamond in hardness and nearly impossible to change thermally by normal means.
