Abstract

L'invention concerne un dispositif à cycle frigorifique, selon lequel un circuit de surfusion peut présenter une performance suffisante à l'aide d'une configuration simple. Un dispositif à cycle frigorifique (1) selon l'invention est pourvu d'un tuyau de réfrigérant (8) qui relie un compresseur (2), un échangeur de chaleur d'extérieur (3), un circuit de surfusion (5), un détendeur d'intérieur (6) et un échangeur de chaleur d'intérieur (7) et à travers lequel un réfrigérant est amené à s'écouler. Le tuyau de réfrigérant (8) comprend : un tuyau de circuit principal (31) pour faire circuler le réfrigérant à travers le compresseur (2), l'échangeur de chaleur d'extérieur (3), le circuit de surfusion (5), le détendeur d'intérieur (6) et l'échangeur de chaleur d'intérieur (7) ; un tuyau de circuit de dérivation (32) qui se ramifie entre les extrémités du tuyau de circuit principal (31), qui relie le circuit de surfusion (5) et le détendeur d'intérieur (6), et qui dévie le réfrigérant vers le compresseur (2) ; et une section de ramification (33) entre le tuyau de circuit principal (31) et le tuyau de circuit de dérivation (32). La section de ramification (33) comprend une section de tuyau amont (51), une section de tuyau de ramification de circuit principal (52) qui se ramifie vers le haut à partir de la section de tuyau amont (51) et s'étend vers le détendeur d'intérieur (6), et une section de tuyau de ramification de circuit de dérivation (53) qui se ramifie vers le bas à partir de la section de tuyau amont (51) et s'étend vers le circuit de surfusion (5).
