\n\n Orifices de ventilation\n \n <\/h1>[vc_empty_space][vc_column_text css=\u00a0\u00bb\u00a0\u00bb]\u00c0 quoi les orifices de ventilation servent-ils ?<\/strong><\/p>\n

Il faut que, \u00e0 l\u2019int\u00e9rieur de la cuisine, il arrive au moins la m\u00eame quantit\u00e9 d’air que celle qui sert \u00e0 la bonne combustion du gaz. En outre, il faut tenir compte que l’aspiration de la hotte, qui n’a pas d’air arrivant de l’ext\u00e9rieur, peut engendrer une d\u00e9pression qui emp\u00eache l’expulsion totale des fum\u00e9es. Pour \u00e9liminer ces deux probl\u00e8mes, l’introduction naturelle de l’air peut s’effectuer directement \u00e0 travers des ouvertures de ventilation permanentes r\u00e9alis\u00e9es dans le mur du local donnant vers l’ext\u00e9rieur. Telles ouvertures, r\u00e9gies par la Norme UNI7129, doivent r\u00e9pondre aux exigences suivantes :
\n– avoir une section de passage nette d’au moins 6 cm pour chaque kW de d\u00e9bit thermique install\u00e9, avec un minimum de 100 cm2<\/sup> ;
\n– si la table de cuisson n’est pas \u00e9quip\u00e9e d’un thermocouple de s\u00e9curit\u00e9 (dispositif qui coupe l’arriv\u00e9e du gaz en cas d’extinction de la flamme), il sera n\u00e9cessaire de r\u00e9aliser une autre ouverture pour arriver \u00e0 une section minimale de ventilation de 200 cm2<\/sup>.
\nIl est recommand\u00e9 de r\u00e9aliser la deuxi\u00e8me ouverture de ventilation dans la partie inf\u00e9rieure de la pi\u00e8ce, car le GPL, ayant une densit\u00e9 relative sup\u00e9rieure \u00e0 celle du m\u00e9thane, a tendance \u00e0 s\u2019accumuler vers le bas et n\u00e9cessite un apport d\u2019air plus important pour la combustion.<\/p>\n

La norme permet \u00e9galement la ventilation indirecte moyennant le pr\u00e9l\u00e8vement de l’air depuis des pi\u00e8ces adjacentes \u00e0 condition que le local adjacent soit dot\u00e9 de ventilation directe et qu’il ne soit pas utilis\u00e9 comme chambre \u00e0 coucher ou bien que ce ne soit pas un local avec un haut risque d’incendie (garage, chaufferie).\u00a0En outre, le local adjacent ne doit pas \u00eatre mis en d\u00e9pression par rapport \u00e0 la pi\u00e8ce qui doit \u00eatre ventil\u00e9e, par effet d’un autre appareil fonctionnant avec un combustible quelconque (chemin\u00e9e, po\u00eale…) ou bien avec un dispositif d’aspiration pour lequel une arriv\u00e9e d’air n’a pas \u00e9t\u00e9 pr\u00e9vue. Le flux d’air provenant du local adjacent peut s’effectuer \u00e0 travers des ouvertures permanentes ou bien, en cas de portes s\u00e9parant les deux pi\u00e8ces, en augmentant l’espace entre le bas de porte et le sol (mini. 2 cm).\u00a0Valcucine conseille d’effectuer, l\u00e0 o\u00f9 il est possible de le faire, des ouvertures de ventilation dans un local adjacent \u00e0 la cuisine afin d’\u00e9viter les fastidieux courants d’air froid (l\u2019air a le temps de chauffer avant d’atteindre la cuisine) et les odeurs ne vont pas vers les autres pi\u00e8ces de la maison, mais elles sont achemin\u00e9es dans la bonne direction.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=\u00a0\u00bb21919″ img_size=\u00a0\u00bb800×600″][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
