Abstract

L'invention concerne un déshumidificateur (1) pourvu d'un évaporateur (31), d'un premier condenseur (33a), d'un second condenseur (33b), d'un boîtier (10) et d'un ventilateur soufflant (21). A l'intérieur du boîtier (10), un espace de mélange (41) est formé entre le premier condenseur (33a) et le second condenseur (33b). Une partie d'air aspiré à l'intérieur du boîtier (10) par le ventilateur soufflant (21) est envoyée à l'espace de mélange (41) par l'intermédiaire de l'évaporateur (31) et du premier condenseur (33a) dans cet ordre. Une partie de l'air aspiré à l'intérieur du boîtier (10) par le ventilateur soufflant (21) est envoyée à l'espace de mélange (41) sans traverser l'évaporateur (31) et le premier condenseur (33a).
