Question about Electrolux Chill Flex Pro

According to the Electrolux website, it should be capable of this, but it all depends on the chamber it has to cool. In theory it is 125m^3. According to some evaluations it is rather slow if there is too much space, so you have to be very careful not to exceed the indicated limit.

As for the insulation, this too is theoretically feasible, as long as the pipe goes outside and the window is well covered. Then there is also this accessory which serves to do the insulation: Electrolux Fensterdichtungssatz EWS01

my window is a skylight in an attic, but I think this accessory is fine.

thank you very much, 125 sqm max? then i think it's fine, my room is 25 sqm! x the accessory ok thank you.
