Title (EN) REFRIGERATION CYCLE DEVICE
(FR) DISPOSITIF À CYCLE FRIGORIFIQUE
(JA) 冷凍サイクル装置
Abstract:
(EN) Provided is a refrigeration cycle device wherein each of a plurality of sets of air heat exchangers is a set of one or more stand-alone heat exchangers. The stand-alone heat exchanger has an upper header pipe, a lower header pipe, heat transfer tubes, and fins. During cooling operation, a serial refrigerant channel is formed in which the air heat exchangers of each set circulate refrigerant in series and in which the refrigerant flows from the top to the bottom of the heat transfer tubes of all of the stand-alone heat exchangers. During heating operation, a parallel refrigerant channel is formed in which the air heat exchangers of each set circulate the refrigerant in parallel and in which the refrigerant flows from the bottom to the top of the heat transfer tubes of all of the stand-alone heat exchangers.
(FR) L'invention concerne un dispositif à cycle frigorifique dans lequel chacun d'une pluralité d'ensembles d'échangeurs de chaleur à air est un ensemble d'un ou de plusieurs échangeurs de chaleur autonomes. L'échangeur de chaleur autonome comprend un tuyau collecteur supérieur, un tuyau collecteur inférieur, des tubes de transfert thermique et des ailettes. Pendant le refroidissement, un canal de fluide frigorigène en série dans lequel les échangeurs de chaleur à air de chaque ensemble font circuler un fluide frigorigène en série et dans lequel le fluide frigorigène s'écoule du haut vers le bas des tubes de transfert de chaleur de tous les échangeurs de chaleur autonomes, est formé. Pendant le chauffage, un canal de fluide frigorigène parallèle dans lequel les échangeurs de chaleur à air de chaque ensemble font circuler le fluide frigorigène en parallèle et dans lequel le fluide frigorigène s'écoule du bas vers le haut des tubes de transfert de chaleur de tous les échangeurs de chaleur autonomes, est formé.
(JA) 冷凍サイクル装置においては、複数組の空気熱交換器のそれぞれの組は、1以上の単体熱交換器を1組として構成され、単体熱交換器は、上部ヘッダ管と下部ヘッダ管と伝熱管とフィンとを有し、冷房運転時には、組ごとの空気熱交換器が直列に冷媒を流通させる直列冷媒流路が形成され、直列冷媒流路では、全ての単体熱交換器が有する伝熱管に上から下に冷媒を流通させ、暖房運転時には、組ごとの空気熱交換器が並列に冷媒を流通させる並列冷媒流路が形成され、並列冷媒流路では、全ての単体熱交換器が有する伝熱管に下から上に冷媒を流通させる。
