La bouteille de d\u00e9couplage permet la communication hydraulique entre le circuit primaire (production) et les circuits secondaires (utilisation).<\/span><\/p>\n<\/div><\/section>\n

Elle est plac\u00e9e verticalement, l’ordre des raccordements est fonction des temp\u00e9ratures du fait de la convection naturelle interne. Elle devra \u00eatre \u00e9quip\u00e9e d’un syst\u00e8me de purge d’air et d’un dispositif de chasse. L’entraxe entre 2 piquages suit la r\u00e8gle des 3 \u00ab\u00a0d\u00a0\u00bb, d \u00e9tant le diam\u00e8tre int\u00e9rieur de la canalisation primaire<\/span><\/p>\n

Le diam\u00e8tre minimum de la bouteille \u00ab\u00a0D\u00a0\u00bb d\u00e9pend du diam\u00e8tre int\u00e9rieur de la canalisation primaire d et du nombre de d\u00e9part n.<\/span><\/p>\n<\/div><\/section><\/div>\n

On dit que la bouteille de d\u00e9couplage fonctionne en \u00ab\u00a0casse-pression\u00a0\u00bb lorsque le d\u00e9bit primaire est sup\u00e9rieur \u00e0 la somme des d\u00e9bits secondaires.
\n<\/span><\/p>\n

Ceci occasionne une temp\u00e9rature de d\u00e9part secondaire \u00e9gale \u00e0 la temp\u00e9rature d’arriv\u00e9e primaire, et un flux descendant dans la bouteille.<\/span><\/p>\n<\/div><\/section><\/p><\/div>\n

On dit que la bouteille de d\u00e9couplage fonctionne en \u00ab\u00a0m\u00e9lange\u00a0\u00bb lorsque le d\u00e9bit primaire est inf\u00e9rieur \u00e0 la somme des d\u00e9bits secondaires.
\n<\/span><\/p>\n

Ceci occasionne une temp\u00e9rature de d\u00e9part secondaire inf\u00e9rieure \u00e0 la temp\u00e9rature d’arriv\u00e9e primaire, et un flux montant dans la bouteille.<\/span><\/p>\n<\/div><\/section><\/p><\/div>\n

De part ses dimensions, il est indispensable de calorifuger la bouteille.<\/span><\/p>\n

Les vannes de barrage et d\u2019\u00e9quilibrage peuvent \u00eatre pos\u00e9es au plus proche de la bouteille.<\/span><\/p>\n

Le trac\u00e9 des tuyauteries de raccordement doit permettre la libre dilatation due aux variations de temp\u00e9rature.<\/span><\/p>\n

La bouteille servira de pot \u00e0 boue du circuit primaire, la robinetterie de vidange doit permettre les chasses.<\/span><\/p>\n

La bouteille favorisera le d\u00e9gazage de l\u2019eau et stockera l\u2019air d\u00e9gag\u00e9 au point haut, il sera n\u00e9cessaire de r\u00e9aliser des purges manuelles et pour cela, de ramener les vannes de purge \u00e0 hauteur d\u2019homme.<\/span><\/p>\n

La vitesse de circulation doit \u00eatre voisine de 0,1 m\/s.<\/span><\/p>\n

La bouteille, de part son volume, augmente la capacit\u00e9 thermique de l\u2019installation.<\/span><\/p>\n

Il est int\u00e9ressant d\u2019installer des thermom\u00e8tres sur chaque piquage.<\/span><\/p>\n<\/div><\/section>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":1554,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[],"class_list":["post-1545","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-theorie-appliquee"],"_links":{"self":[{"href":"https:\/\/sibam89.fr\/index.php?rest_route=\/wp\/v2\/posts\/1545","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sibam89.fr\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sibam89.fr\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sibam89.fr\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/sibam89.fr\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1545"}],"version-history":[{"count":12,"href":"https:\/\/sibam89.fr\/index.php?rest_route=\/wp\/v2\/posts\/1545\/revisions"}],"predecessor-version":[{"id":1564,"href":"https:\/\/sibam89.fr\/index.php?rest_route=\/wp\/v2\/posts\/1545\/revisions\/1564"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sibam89.fr\/index.php?rest_route=\/wp\/v2\/media\/1554"}],"wp:attachment":[{"href":"https:\/\/sibam89.fr\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1545"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sibam89.fr\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1545"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sibam89.fr\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1545"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
