- Unité de ventilo-convecteur selon la revendication 10, 11 ou 12, dans laquelle les premier (7) et second (8) ventilateurs sont deux ventilateurs tangentiels qui s'étendent à cheval sur les deux éléments latéraux en forme de plaque (10) de l'ossature intérieure (3), sur des côtés opposés de la structure tubulaire (12) délimitée par les mêmes organes latéraux transversaux (11), chacun étant localement sensiblement tangent à un organe latéral (11) respectif.
- Unité de ventilo-convecteur selon l'une quelconque des revendications 9 à 13, dans laquelle ladite ossature intérieure (3) et ladite enveloppe ou ledit revêtement extérieur (4) sont conformés/structurés de manière à former/délimiter également deux compartiments de service (14, 15) latéraux qui sont situés à l'intérieur du carter en forme de boîte (2), sur des côtés opposés du conduit traversant (5), de manière à être tous deux effleurés par la paroi (P) ou adjacents à celle-ci ; un premier compartiment de service (14) étant adapté pour accueillir une unité de commande électronique (9) et facultativement également un ou plusieurs capteurs de température et/ou des connecteurs électriques qui permettent de connecter l'unité de ventilo-convecteur au réseau électrique externe ; le second compartiment de service (15) étant adapté pour accueillir les raccords hydrauliques, les vannes d'arrêt et/ou les autres composants hydrauliques qui permettent de connecter ledit échangeur thermique (6) au circuit hydraulique externe.
- Unité de ventilo-convecteur selon l'une quelconque des revendications précédentes, caractérisée en ce qu'elle comprend en outre un plateau de collecte de condensation (16).
- Unité de ventilo-convecteur selon l'une quelconque des revendications précédentes, dans laquelle le filtre à air (17) est placé le long du segment initial du conduit traversant (5), en amont de l'échangeur de chaleur (6) et de la bifurcation du conduit traversant (5), de manière à être traversé par la totalité du flux d'air qui s'écoule à travers le conduit traversant (5).
- Unité de ventilo-convecteur selon l'une quelconque des revendications précédentes, dans laquelle l'unité de commande électronique (9) est programmée/configurée pour activer lesdits moyens électromécaniques (19, 29) lorsque les heures de fonctionnement de l'unité de ventilo-convecteur (1) sans entretien du filtre à air (17) atteignent une valeur limite donnée.
- Unité de ventilo-convecteur selon l'une quelconque des revendications précédentes, dans laquelle l'unité de commande électronique (9) est programmée/configurée pour interrompre/empêcher le fonctionnement desdits ventilateurs (7, 8) lorsque les heures de fonctionnement de l'unité de ventilo-convecteur sans entretien atteignent une valeur limite donnée.
