Cooling with the Ice Maker?

[NewWorldDan]

Yea verily, I nearly forgot one of the most important heat production/deletion sources in the game - toilets.  The lavatory takes in 5 kg water at any temperature and transforms it to 11.7 kg polluted water at 37 C.  If you're in a heat or water crunch, you can turn off the sinks so your dupes get food poisoning and use the toilets twice as often.   So often we circulate the toilet water on an infinite loop and only divert the excess.  When really, you can send hot water to the toilets, cool it there, dump more heat into it on the way to the SPOM for maximum heat removal potential.  Sending 67C water to the toilets (right on the edge of scalding) destroys 1044 DTU/s per duplicant.  Double that if they have food poisoning.  Cleaning and heating that same water to near boiling on the way to the spom destroys an additional 4900 DTU/s per duplicant.  

 

Off on another direction here, I really wish there was a way to farm oxyferns and wheezeworts for more seeds.  I don't care if it's slow - it should be slow - but you can't build a large scale solution with them without more seeds.  As for the complaint that wheezeworts require fertilizer, it's a trivial amount and an autosweeper can do that for you.  Fill a storage bin full of phosphorite and never worry about it again.

Algae Terrariums are extremely potent for heat deletion, as they take water at any temperature and turn it into 30 C pwater. Two caveats: this would appear to be a bug because it's contrary to the tooltip which states the pwater is at input temperature, and the "yucky lungs" debuff in Spaced Out make Terrariums a less generally OP way of converting hot water into breathable air, though they are still potent at temperature regulation (they are also useful on cold maps for elevating freezing cold water to warm temperatures for feeding reed fiber or whatever).

Maybe, but the discussion is about the current state of things, not a hypothetical future, ergo Battery Modules annihilate your point about battery heat.

Actually, having started this discussion, I placed no limit of this type on it. You are imagining things.

No, the real problem is that when you turn the ice into the building, it acts like it has 1/5th of its mass so you are giving up 80% of the cooling capacity that ice had.

The ice block has that trait same as tempshoft plate!?

 

The wiki says

as only 20% of buildings mass is considered for heat calculations

well then still better than Ice fan

 

It melt!

 

Otherwise the ice really not doing anything nice for cooling

 

But what if for the water source?

The ice won't turn back to water for nothing? hey hey

All buildings have the 1/5th rule. The only exceptions are tiles (e.g. farm tile), buildings that are tiles act as tiles rather than buildings. A few buildings have both a building and tiles and it can get a bit funky, examples are Solar Panel and Rocket Platform, the free tiles actually give these exceptional buildings a lot more heat capacity than their materials. 

How good ice tempshift plates are for cooling really depends what you are cooling and how cold the ice is. Say you want to cool a bristle blossom farm that is at 30 C, and the ice is -2 C, in this case the fact that it takes only 1/5th as much heat to melt it is quite irrelevant to how much cooling is provided, as most the potential cooling is coming from the liquid phase.

On the other hand, say you want to cool a Nosh Sprout farm which is at 1 C, in this case ALL the potential cooling has to come from the solid phase of ice, so you are simply losing 80% of the potential cooling by using ice in building form rather than tile or debris. One trick I've used is trapping ice debris in a mechanical airlock, entombed debris transfers heat quite fast, depending exactly how you configure things you can have the water leak out once the ice melts, or have it disappear from existence.
