You need fans to blow the air OUT not in, and create a chimney effect between opposite sides of the building.
A small out blowing fan can be enough, if run all night.
Blowing out will cause air to be sucked in from the opposite side. Having multiple fans will only mess up the air flow and reduce the efficiency. Better two fan on the same outgoing window.
Of course, that will never cool down more than a few degrees above outside temp because walls thermal cycle will bring inside day heat at night and bring inside night cool in daytime. Specially thick or well insulated walls are designed to do exactly that.
So yes walls will warm you up at night, that is not avoidable. A well insulated wall will do that instead of bringing heat in during daytime… But heat is there and must be dissipated that’s physics. Night time is the best option.
Edit: blow out at night. During daytime blow around, best way to keep cool is move that hot layer of air that get stick to your skin with a fan. Same temperatures but so much more bearable.












Sarà un problema di federazione con Lemmy, ma non si può vedere un post titolato solo “salve a tutti”…
Forse in futuro puoi mettere un titolo vero?
