Floor ventilation device, comprises air exit part placed on top of open base part connected to ventilation duct in floor via vertical air inlet

摘要

An base part (11) with an open top side is mounted in the floor (5) so that it extends in a vertical direction and is connected to a ventilation duct in the floor via an essentially vertical air inlet (4). An air exit part (12) with a closed top side is wider than the top of the base part, so that an air gap (13) is formed between the overlapping vertical walls of the two parts when the exit part is placed on top of the base part. An Independent claim is also included for a ventilation method using this device.
