Abstract
(EN)
The present invention appropriately carries out a cleaning operation in an air conditioner. This air conditioner is provided with: a refrigeration cycle having a compressor that compresses a refrigerant and an indoor heat exchanger that cools or heats air in an air-conditioning room; a control device that controls the refrigeration cycle so as to carry out the cleaning operation for cleaning the surface of the indoor heat exchanger; an indoor fan that blows air to the indoor heat exchanger; and an air state sensor that detects the temperature or the humidity of air flowing-in from the air-conditioning room, wherein the control device has functions (S102, S104) for driving the indoor fan for a prescribed period before the execution of the cleaning operation, and functions (S110, S120) for carrying out the cleaning operation on the condition that the detection result of the air state sensor is within a first prescribed range after the driving of the indoor fan.

La présente invention réalise de manière appropriée une opération de nettoyage dans un climatiseur. Ledit climatiseur comporte : un cycle frigorifique ayant un compresseur qui comprime un réfrigérant et un échangeur de chaleur d'intérieur qui refroidit ou réchauffe l'air dans une salle de climatisation ; un dispositif de commande qui commande le cycle frigorifique de façon à effectuer l'opération de nettoyage consistant à nettoyer la surface de l'échangeur de chaleur d'intérieur ; un ventilateur intérieur qui souffle de l'air vers l'échangeur de chaleur d'intérieur ; et un capteur d'état d'air qui détecte la température ou l'humidité de l'air s'écoulant depuis la salle de climatisation, le dispositif de commande ayant des fonctions (S102, S104) pour entraîner le ventilateur d'intérieur pendant une période prescrite avant l'exécution de l'opération de nettoyage, et des fonctions (S110, S120) consistant à exécuter l'opération de nettoyage à la condition que le résultat de détection du capteur d'état d'air s'inscrive dans une première plage prescrite après l'entraînement du ventilateur d'intérieur.
