Water cooler (easy and low energy)

[SamLogan]

Hello,

I'm not if this set up has been already post but here's the watercooler I use. It really easy to make and have a very low energy cost. 

Step 0 : three pool (hot water from geyser, cold room, warm room or plants) - Debug mode for the demonstration

Step 1 : in the cold room make some radiant pipe in Tungsten or Gold, like this

Step 2 : make a Liquid Pipe Thermo Sensor

Step 3 : add a liquid shutoff like this

Step 4 : add a liquid shutoff for your geyser

Step 5 : connect all the pipes like this

Step 6 : add automation to open the first shutoff if the water enough cold (choose the number) and close the second one to don't add more hot water.

The hot will stay in the cooling room by turn around in the radiant pipe as far as the temperature wil above X°C/F.

I obtain 80°C -> 15°C in few cycles.

Piping water through potentially sub-zero temperatures is always risky because pumps aren't guaranteed to output 10kg packets. You can see two in your screenshot.

Oh, yes, My old chiller design needed specific circuitry to avoid that. Basically the the first few seconds after pump start and pump stop, you need to reroute and not pipe through the cold. And on loading the game you get the same problem, but cannot do anything about it, or at least I found no reliable way to detect the game has been loaded. I do admit, I did not look very hard though. That is why I now pump Hydrogen around, the new radiant gas pipes make that pretty efficient. Maximum heat transfer is around 90kW for 80C temperature difference, i.e. around 8 Wheezeworts.An alternative may be doors, metal blocks and temp shift plates, but I am not convinced yet that works better. definitely is more dependent on usage profile. Apparently, you can also get the hydrogen circling for free at the moment, which sounds like a bug to me.

I recommand to plug the Thermo Sensor Pipe inside the cooling room if you want to avoid water to freeze (ie. if i want the water to be at 5c it could already be under 0c inside the weezeworth room, 2 tiles away on the right then)
Plus add some tempshift plates all around the room for the same problem.
More, add automated doors under weezes pots when the room reach too cold temp.
A last : keep your tungsten for hotter build (volcanoes, magma...)

(This build still probably usefull on early before better setup i guess.)

The problem with passive builds is the throughput.

It's great if you just want a trickle of water every few cycles, but as soon as you need anything greater than a couple of hundred kilos per cycle, it goes completely out of the window.
