Abstract
(EN)
This refrigeration cycle apparatus is provided with: a compressor; a condenser; a decompression device; an evaporator; and a blower fan. The evaporator includes a fin (30) and a heat transfer pipe (20). The fin (30) includes a first region (30a) into which the heat transfer pipe (20) is inserted, and a second region (30b) which projects from the heat transfer pipe (20) in a direction opposite to a blowing direction during a heating operation. An outdoor fan is configured to blow air from the second region (30b) toward the first region (30a) during the heating operation, and blow air from the first region (30a) toward the second region (30b) after execution of a defrosting operation, during the heating operation, for melting frost deposited on the evaporator.

Appareil à cycle frigorifique qui comprend : un compresseur; un condenseur; un dispositif de décompression; un évaporateur; et un ventilateur soufflant. L'évaporateur comprend une ailette (30) et un tuyau de transfert de chaleur (20). L'ailette (30) comprend une première région (30a) dans laquelle le tuyau de transfert de chaleur (20) est inséré, et une seconde région (30b) qui fait saillie à partir du tuyau de transfert de chaleur (20) dans une direction opposée à une direction de soufflage pendant une opération de chauffage. Un ventilateur extérieur est configuré pour souffler de l'air à partir de la seconde région (30b) vers la première région (30a) pendant l'opération de chauffage, et souffler de l'air à partir de la première région (30a) vers la seconde région (30b) après l'exécution d'une opération de dégivrage, pendant l'opération de chauffage, pour faire fondre le givre déposé sur l'évaporateur.
