Are temp shifts broken?

[SharraShimada]

If usually use the following setup:

2 polymer presses with 4-5 tiles space in between. 

left and right of each press 1 wheezewort.

The back covered in diamond temp shift plates.

Above the presses thermo sensor, set to 40°C as a shutoff for the presses to prevent overheating.

 

But this time, they overheat in 3-4 seconds, while the thermo sensor wont recognize any significant heat buildup (1-2°C at sensor, 50°C at press)

Also the worts seem to not cool as much as i´m used to in this setup. 

 

Any ideas? Did i miss a change?

what material are your p-presses made with?

[SharraShimada]

Normaly i make them from wolframite. That gives a 10-20°C buffer because the thermo sensor does nit sit really near. For over a year now, this worked fine. I tired it also with gold amalgam, but they rise up to 125°C+ and brake too. 

[Neotuck]

Well a lot of thermal balancing has been done over the past year.  Seems in your design they heat up too fast to trigger the thermal sensor.  Also one wheezie per press seems unlikely.  I don't know the math but I'm sure there's some one in the forums who can calculate how many wheezies you need to keep a press cool

Personally I always drip water on them

I´ve just noticed another issue. that may be related... 

In my base i have a oxygen-plant, piping the O² to the main base. This works normally also very well.

But this time, O² gets stuck near the vents, and seems to ignore mesh doors, and airflow tiles mostly.

It looks like the gas-flow (and therefor heat transfer) is somelike stuck.

 

And for your answer, No 2 worts per perss is not enough to keep them running all the time. But thats okay. The issue is, the heat is not even remotely transfered away from the presses, so they overheat, and the sensors wont shut them down.

have a screenshot?  airflow works fine in my base and I also use mesh doors/airflow tiles

As you can see, the pipe is full, because the vent is overpressured. In the gas overlay one sees, it fills hardly the med bay, and stops flowing at the airflow tiles, while the base is mostly way underpressured.

And another screen of my polymer press setup, that worked well all the time, but not in this save, for yet unknown reasons.

I attached also the save file, if one wants to take a look.

the problem is placement, you have the vent tucked into a corner with half of it blocked with tiles

Vents need to be near the middle of the base with plenty of open space to allow pressure to equalize 

your base is too large for just 3 vents to handle, even if you have enough electrolyzers you need to spread them out, branch the pipes and add new vents

As for the polymer presses, they seem to work fine, I set the thermal sensors to 50C and they have been running non stop for 2 cycles and are only 10 degrees past the sensors

[SharraShimada]

Okay, i will adress the placement issue.

3 vents are always enough, because the dupes are almost all the time outside (minor the sleeping shift, and the cook), so they consume very little inside. In fact, this base is a bit smaller than usual ^^ But you´re right, if they are all at home all the time, it would not be enough.

As for the polymer press, this bevavior is wierd. I also reloaded the save, and the issue persitet. Will try that again. Anyway thanks for your help.

what do you have the temp set to?

I only ran it for 2 cycles but they didn't seen to be overheating and the sensors seemed to keep up with only a 10 degree difference

[SharraShimada]

I had it at 40. But the presses overheatet so fast, the sensor would not notice anything in that time. But you´re right... i reloaded the save, and tadaaaa, the presses run like hell. Had to be a glitch.

Buildings don't transfer with buildings.

e.g. pressers don't transfer heat with temp shift.

 

Here, the heat transfer route is    presser A <--> gas behind A <--> gas behind B <--> presser B

Temp shift can only speed up      gas behind A <--> gas behind B.

But the bottle neck might be        gas behind presser <--> presser

 

To speed up                                 gas behind presser <--> presser

Just replace gas with water.

[SharraShimada]

No need to use water. As i say before, it worked for months perfectly. I dont know what caused the problems. I had reloaded the save, and it persisted. After another reload, it got working again. 

Its pretty fine with just gas filled.

Ive never had much luck with building polymer press on mesh tiles i would just replace the mesh with granite and move the mesh to the side this will hold a bit of water under the press and greatly help with heat transfer 

But to get back to the question i do remember a transfer plate bug that would cause them to stop working if you reloaded the game try rebuilding them and see what happens maybe he bug is back

The press produces 32.5 KDTU. The steam emitted is another 7 KDTU. So you need 4 wheezes for one press or 7 wheezes for two, as each wheeze is -12 KDTU. 

I've used them in ~4000 g/tile H2 with no problems. If you let the room cool down first, the steam will instantly condense into water that you can pump out.

Sorry, no screenshot as I've moved on to dreckos since, but it was kind of like your setup, with more wheezes and no tempshifts. (Really, those aren't necessary.)

this.  just let them sit in the water they make and let it flow to their side and it will never overheat as long as you do not send it overheated oeyroleum.
