Abstract

L'invention concerne un système de climatisation (10) avec un circuit de réfrigérant (11), le système de climatisation (10) comportant un système de détection de fuite (32). Le système de détection de fuite comprend un capteur de température ambiante, un capteur de température d'entrée pour détecter une température de réfrigérant au niveau d'une entrée de réfrigérant d'un évaporateur de réfrigérant et un capteur de température de sortie pour détecter une température de réfrigérant au niveau d'une sortie de réfrigérant. ) de l’évaporateur de réfrigérant (15). Les capteurs (34, 36, 40) sont couplés à une unité de calcul (38). L'invention concerne en outre un procédé de détection de fuite dans lequel une température ambiante de la pièce à conditionner (18) avant l'évaporateur de réfrigérant (15) du côté entrée d'air (41), une température d'entrée de réfrigérant à l'entrée de réfrigérant (16) d'un évaporateur de réfrigérant (15) et une température de sortie du réfrigérant la sortie de réfrigérant (17) de l'évaporateur de réfrigérant (15) est détectée.
