Abstract

Climatiseur évitant la dégradation des parties vissées d’un panneau décoratif ou climatiseur agencé de façon que, même dans le cas où un conduit de sortie d’air est fixé ultérieurement, le débit d’air vers le conduit de sortie puisse être facilement régulé sans augmentation du nombre de pièces. Cette partie d’un panneau décoratif, qui est fixée à un corps principal d’unité par un organe de fixation et où des contraintes sont produites par l’organe de fixation, est dotée d’une section de logement fermée servant à loger une partie exposée de l’organe de fixation à un état sensiblement fermé. Par ailleurs, une surface de raccordement d’un conduit de sortie d’air dans un caisson possède des trous à défoncer espacés les uns des autres ; lesdits trous à défoncer se situent le long des bords des orifices disposés pour être ouverts et peuvent être mis sélectivement en communication avec le conduit de sortie d’air.
