Then inform yourself about the physics, come on. Just a bunch of smart alecks here. A climate where the dew point is above 22 degrees Celsius (72°F) is practically impossible in Germany. Weather is considered muggy when the dew point reaches 16 or 17 degrees Celsius (61 or 63°F). For the dew point to reach 22 degrees Celsius (72°F), you need almost 50% more moisture than what we understand as muggy conditions. Those are conditions typical for Florida in summer, but such considerations are completely irrelevant for Germany, let alone Berlin.
In practice, with a properly and correctly installed ceiling cooling system, you have zero problems and always maintain the perfectly desired temperature without the disadvantages of an air conditioning system. The only downside is that it costs a lot of money.

Rather, the ceiling surface almost takes on the temperature of the coolant. That’s correct, and when underfloor heating is used in a new build, the floor temperature will also reach around 35 degrees Celsius (95°F). In older buildings with a flow temperature of 45-50 degrees Celsius (113-122°F), the floor can get as warm as 45-50 degrees Celsius (113-122°F). People living in older homes with underfloor heating sometimes end up with burns on their feet. 🙁
😱 That’s really nonsense. 🙁
Air practically has no heat storage capacity. If you cool the ceiling down to 22 degrees Celsius (72°F), then the room temperature will be about 22 degrees Celsius (72°F) as well. There is no need to achieve more than that, which is why an expert CALCULATES this. What we amateurs, including you who are the biggest amateur here, calculate and discuss doesn’t matter. The expert calculates it so that the ceiling reaches 22-23 degrees Celsius (72-73°F), but not less.
Only if a pseudo-expert like you does it on their own, the ceiling might drop to 15 degrees Celsius (59°F), making the house extremely cold and causing mold. That’s why there are experts. So, just leave it.
Cooling the ceiling to 15 degrees Celsius (59°F). Honestly, such nonsense to the tenth power. 🙁

Now he wants to cool the ceiling to 12 degrees. OMFG...
You learned a few formulas but don’t know how to apply them. The typical problem in the ivory tower.
I won’t respond to your nonsense any further. It’s complete nonsense from start to finish.But you’re making it very easy for yourself now. If you’re so convinced of your position, it would be interesting for me to know which points in @Knallkörper’s explanation you consider nonsense.
There is no doubt that ceiling cooling/concrete core activation can work, but it also involves additional factors that need to be taken into account.
I find it a waste of time to argue with such a narrow-minded theorist. This method is used hundreds of thousands of times in Germany without any issues, no moisture problems, and no noise.
If the firecracker now wants to stomp around on the floor and miscalculate three times and make five mistakes, let them do it.
