Abstract

L'invention concerne un appareil de climatisation qui permet de déterminer une quantité précise de fluide frigorigène par stabilisation de la pression de compression, même lorsqu'une température extérieure varie pendant l'opération de détermination de la quantité de fluide frigorigène. Un capteur de température extérieure (36) détecte une température extérieure (Ta). Un ventilateur extérieur (28) envoie de l'air extérieur dans un échangeur de chaleur extérieur (23) qui fonctionne comme compresseur. Une section de commande PI (8) commande le ventilateur extérieur (28) tout en faisant varier un gain selon la température extérieure (Ta). Dans la commande PI, une pression de décharge (Pd) provenant d'un compresseur (21) est ajustée pour être conservée de façon stable pendant un temps prescrit, et une quantité de fluide frigorigène dans un circuit de réfrigération (10) est détremineé à l'aide de la quantité d'état du fluide frigorigène s'écoulant dans le circuit de réfrigération (10).
