Patent

CA 2303142

The invention concerns a device regulating the temperature of premises by means of a secondary air flow blown therein, comprising an upstream duct (1) communicating with means supplying pressurised air, ending in a converging element (11) emerging into a downstream duct (3) communicating with the premises. Said device is characterised in that a substantially rotating solid (15a), capable of being positioned along the convergent element (11) longitudinal axis, is arranged at least partially upstream of the outlet thereof, so as to define between the substantially rotating solid (15a) outer surface and the convergent element (11) inner wall a ring-shaped channel the size of which depends on the position of said solid (15a) relative to said wall.

Image La présente invention concerne un dispositif de régulation en température d'un local au moyen d'un flux d'air pulsé dans celui-ci, comportant une canalisation amont (1) en communication avec des moyens d'alimentation en air sous pression, qui se termine par un élément convergent (11) débouchant dans une canalisation aval (3) en communication avec le local. Ce dispositif est caractérisé en ce qu'un solide (15a) sensiblement de révolution, positionnable suivant l'axe longitudinal de l'élément convergent (11), est disposé au moins partiellement en amont de l'orifice de sortie de celui-ci, de façon à définir entre la surface externe du solide sensiblement de révolution (15a) et la paroi interne de l'élément convergent (11) un canal annulaire dont l'importance dépend de la position dudit solide (15a) par rapport à ladite paroi.
