Title (EN) KITCHEN VENTILATION SYSTEM
(FR) SYSTÈME DE VENTILATION DE CUISINE
Abstract:
(EN) Described herein is a kitchen ventilation system, comprising: a kitchen hood communicative with a kitchen exhaust duct; a fan communicative with the hood to create an air flow through the hood and to the exhaust duct; a fire barrier air filter mounted to the hood to receive and filter the air flow, the fire barrier air filter comprising a plurality of elongate extruded bodies in parallel alignment; each extruded body bound by first and second opposing concave surfaces and first and second baffle surfaces, the first and second baffle surfaces oriented transverse to the air flow; and at least one of the of the first and second concave surfaces oriented in facing opposition to a neighboring concave surface provided by a neighboring extruded body to form a cooperating pair of facing concave surfaces, the pair of facing concave surfaces defining a narrow longitudinal inlet gap, a narrow longitudinal outlet gap, and a longitudinal tubular chamber communicating therebetween. A kit providing at least a fire barrier air filter of the system and instructions for its installation is also described. A method of fire prevention using components of the system or kit is also described.
(FR) La présente invention concerne un système de ventilation de cuisine, comprenant : une hotte de cuisine communiquant avec un conduit d’échappement de cuisine ; un ventilateur en communication avec la hotte pour créer un flux d’air à travers la hotte et vers le conduit d’échappement ; un filtre à air coupe-feu monté sur la hotte pour recevoir et filtrer le flux d’air, le filtre à air coupe-feu comprenant une pluralité de corps extrudés allongés en alignement parallèle ; chaque corps extrudé étant délimité par des première et deuxième surfaces concaves opposées et des première et deuxième surfaces de déflecteur, les première et deuxième surfaces de déflecteur étant orientées transversalement par rapport au flux d’air ; et au moins l’une des première et deuxième surfaces concaves étant orientée de façon opposée face à une surface concave voisine fournie par un corps extrudé voisin pour former une paire en coopération de surfaces concaves opposées, la paire de surfaces concaves opposées définissant un espacement d’entrée longitudinal étroit, un espacement de sortie longitudinal étroit, et une chambre tubulaire longitudinale communiquant entre ceux-ci. L’invention concerne en outre un kit fournissant au moins un filtre à air coupe-feu du système et des instructions pour son installation. L’invention concerne en outre un procédé de prévention des incendies utilisant des composants du système ou du kit.
