A method and device for ventilating and temperature controlling rooms

Abstract

The invention relates to a method for ventilating and temperature controlling rooms according to the principle of dilution ventilation, wherein a primary air flow ( 40 ) is introduced into the ceiling cavity ( 30 ) of a room ( 4 ), which is partitioned from a story ceiling ( 26 ) by a false ceiling ( 31 ) and is introduced into the room ( 4 ) by means of porosities ( 41, 42, 43 ) in the false ceiling ( 31 ), wherein the primary air flow ( 40 ) in the ceiling cavity ( 30 ) produces a secondary air flow ( 33 ) as an induction air flow, which vacuums a room air flow ( 32 ) from the room ( 4 ) into the ceiling cavity ( 30 ), mixes with the secondary air flow ( 33 ) and introduces it into the room ( 4 ) as a tertiary air flow ( 34 ) through the porosities ( 41, 42, 43 ) in the false ceiling ( 31 ).
