so if i understund at winter days when it is about -10 to 10C i only need cold air from outside with some filters for moist, and on hot days very good outtake of hot air from room foloved with aircooling machines.
My farm tolerates up to 95F incoming air during the summer months but is happier using 85F and lower.
so if it is not more than 95F outside you only use air from outside and not aircooling? or that temperature i must set in the room. or that is the same and i just repetiting myself?
