Abstract

L'invention concerne un procédé de détection de fuites dans un système de climatisation (10), dans lequel une température ambiante de la pièce à conditionner (18) devant 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 de réfrigérant est détectée à une sortie de réfrigérant (17) de l'évaporateur de réfrigérant (15). Sur cette base, une température de sortie différentielle est calculée en tant que différence entre la température ambiante et la température de sortie du réfrigérant et une température de différence de l'évaporateur en tant que différence entre la température de sortie du réfrigérant et la température d'entrée du réfrigérant. Une fuite est détectée lorsque la température différentielle de sortie tombe en dessous d'une valeur définie et / ou lorsque la température différentielle de l'évaporateur dépasse une valeur prédéterminée.
