Title (EN) REFRIGERATION CYCLE DEVICE
(FR) DISPOSITIF À CYCLE DE RÉFRIGÉRATION
(JA) 冷凍サイクル装置
Abstract:
(EN) A condenser of a refrigeration cycle device of the present invention is provided with: a first flow channel configured from a first flat heat transfer pipe, a first end portion of which is connected to the compressor, and a second end portion of which has a plurality of flow channels therein; a second flow channel configured from a second flat heat transfer pipe, a first end portion of which is connected to an expanding device, and a second end portion of which has a plurality of flow channels therein; and a joint, to which the first flat heat transfer pipe and the second flat heat transfer pipe are connected, and which bends the flow of a hydrofluoroolefin-based refrigerant between the first flat heat transfer pipe and the second flat heat transfer pipe. The length of the second flow channel is equal to or shorter than that of the first flow channel, and the joint has a recessed section inside, said recessed section being recessed downward.
(FR) L'invention concerne un condenseur d'un dispositif à cycle de réfrigération, comprenant : un premier canal d'écoulement conçu à partir d'un premier tuyau de transfert de chaleur plat, dont une première portion d'extrémité est reliée au compresseur et dont une seconde portion d'extrémité présente une pluralité de canaux d'écoulement en son sein ; un second canal d'écoulement conçu à partir d'un second tuyau de transfert de chaleur plat, dont une première portion d'extrémité est reliée à un dispositif d'expansion et dont une seconde portion d'extrémité présente une pluralité de canaux d'écoulement en son sein ; et un joint, auquel le premier tuyau de transfert de chaleur plat et le second tuyau de transfert de chaleur plat sont reliés et qui courbe l'écoulement d'un fluide frigorigène à base d'hydrofluoroléfine entre le premier tuyau de transfert de chaleur plat et le second tuyau de transfert de chaleur plat. La longueur du second canal d'écoulement est égale ou inférieure à celle du premier canal d'écoulement et le joint présente en son sein une section évidée, ladite section évidée étant évidée vers le bas.
(JA) 冷凍サイクル装置の凝縮器は、第1端部が圧縮機に接続され、第2端部が内部に複数の流路を有する第1扁平伝熱管で構成された第1流路と、第1端部が膨張装置に接続され、第2端部が内部に複数の流路を有する第2扁平伝熱管で構成された第2流路と、第1扁平伝熱管と第2扁平伝熱管とが接続され、第1扁平伝熱管と第2扁平伝熱管との間のハイドロフルオロオレフィン系冷媒の流れを曲げる継手と、を備え、第2流路の長さは第1流路の長さ以下であり、継手は、該継手の内部に、下方に凹んだ凹部を有するものである。
