Abstract

L'invention concerne un climatiseur d'extérieur permettant de climatiser une large zone extérieure. Un échangeur de chaleur extérieur présente un risque d'effets défavorables sur des dispositifs internes si de l'eau, dans un espace contenant un premier échangeur de chaleur (6) agencé dans une section supérieure, est amenée à pénétrer à l'intérieur. Des climatiseurs d'extérieur (100, 100a) comportent, logés à l'intérieur d'un carter (10), un compresseur (1), un premier échangeur de chaleur (6), des premiers bacs de récupération (15, 15a) destinés à collecter de l'eau en provenance d'un espace autour du premier échangeur de chaleur (6), un premier ventilateur (7), un second échangeur de chaleur (3) positionné plus bas par rapport au premier échangeur de chaleur (6), et un second ventilateur (4). De plus, des premières voies d'évacuation (62, 71) sont formées afin d'évacuer l'eau ayant été collectée dans le premier bac de récupération (15).
