Abstract

La présente invention concerne une unité extérieure (100) équipée d'un compresseur (1) et d'un matériau d'insonorisation (300) recouvrant le compresseur. Le matériau d'insonorisation présente une partie surface latérale (300a) et une partie surface supérieure (300b), et la partie surface latérale et la partie surface supérieure sont conçues à partir d'un second élément (320) disposé sur l'extérieur et d'un premier élément (310) qui est disposé sur l'intérieur du second élément et présente moins de rigidité que le second élément. Au niveau de la limite entre la partie surface latérale et la partie surface supérieure, le premier élément de la partie surface latérale ou le premier élément de la partie surface supérieure présente une partie découpée (311) qui a été découpée de façon à réduire la surface de contact entre le premier élément de la partie surface latérale et le premier élément de la partie surface supérieure.
