So we looked around and came across this thing, we bought much cheaper in a hardware store.
I erinner have read me, this device would be enough for 70 square meters, what times of what is wrong. Vllt if there is not so hot and there is a large room with super insulation.
The device comes really only used when it is outside unbearable, so 35 degrees in the sun and upward.
It cools a room, located in the south, of about 25 square meters very well off. 23 degrees are possible. It is then very pleasant at the temperature.
The problem is, as soon as the air is out, the space within a short time reheated, so it would theoretically run overnight, which unfortunately is not in it, because as soon as the compressor is used very loud. Sleep with earplugs recommended since.
Conclusion: For older buildings, as well as in the Upper / attic it helps in a room of 30 square meters maximum. An entire floor so that cool is not it. It has already cost a reason why professional air conditioners good 4-figure sums.
This one I would recommend, if you so want to cool a room. Since it is still loud, it can not be turned on while sleeping.
