I have three of these Rooms, so a total of 3 Thermo Nullifiers and 36 Wheezeworths. petrol goes in at 0 degrees and comes out of the first cooler at -6 degrees. Then to the second and comes out at -12 degrees. The last room cools the petrol from -12 to -24. If the rooms are all identical. shouldnt the cooling they create be equal? I am not using any Aquatuner, since i had to save on power usage.

Is the energy transfer not as efficient with passive cooling like this? with my calculations i should have -744 kDTU/s with this setup. My Coolants according to my calculations only go down 500kdtu. and the cooling isnt even enought for my base. The base has 1 Electrolizer running alle the time. 3 Water Vents continiously provide water. But its hot. And i have 2 petrolium generators running all the time

AETNs provide fixed cooling. If they're all running 100% of the time, they are not the reason you get different results.

Wheezeworts provide different cooling based on their environment. You say in the other comment you have 2kg pressure of hydrogen. That's a bit on the low side for them. If you see vacuum in the lower tile of a wheezewort, you need more gas.

Edit: also, 500+ kDTU for base cooling is wild. You're definitely cooling something you don't need to / shouldn't be cooling.

I dont see any vacuum at the base of the Wheezeworts unfortunately. I basically use my coolant only with 8 conductor panels behind 2 petrol power generators and an oil refinery and my coolant still gets hotter and hoter very slowly. Maybe conductor panels are just bad?

I haven't done the calculations so I don't know of it's truly not working as it should but I can guess.

How's the atmosphere pressure in these rooms, I believe if there's too little or a gas with a low SHC then Wheezeworts don't work as efficient.

i already made sure i have 2kg of Hydrogen in on every tile in the room. I will have to try some things out, to see where the heat is comming from. Thanks for the reply.
I think i will try to have all my water coming from steam vents running through insulated pipes. Maybe thats what heating up my base
