Abstract

La présente invention concerne une unité montée sur le toit pour un climatiseur monté sur le toit. L'unité montée sur le toit est disposée sur une surface de paroi externe d'un toit. L'unité montée sur le toit comprend un couvercle supérieur et un ensemble plaque de base (1), l'ensemble plaque de base (1) comprenant une plaque de base (2) et un élément de couverture (3). Lorsque le couvercle supérieur est monté sur l'ensemble plaque de base (1) et que l'unité montée sur le toit est disposée sur le toit, l'élément de couverture (3) recouvre au moins une partie de la surface de la plaque de base (2) exposée à l'extérieur du couvercle supérieur et du toit. L'unité montée sur le toit utilise un nouvel ensemble plaque de base (1), c'est-à-dire la combinaison de la plaque de base (2) et de l'élément de couverture (3) recouvert sur celle-ci, de sorte que la plaque de base qui utilise un matériau non métallique, tel qu'un matériau de mousse EPP, peut réussir un test de pression de bille dû à la présence de l'élément de couverture, ce qui permet d'obtenir le poids léger de la plaque de base de manière à réduire le poids de l'unité montée sur le toit pour les cas qui sont conformes aux règles de sécurité, ce qui est avantageux pour le montage de l'unité montée sur le toit sur le toit. La présente invention concerne également un climatiseur monté sur le toit, qui est un climatiseur monté sur le toit pour un véhicule.
