Abstract:
(EN) An outdoor unit heat exchanger (3) is provided with a first outdoor unit heat exchanger (3a), a second outdoor unit heat exchanger (3b) and a switching valve (4). The number of a plurality of first refrigerant flow channels (RF1) of the first outdoor unit heat exchanger (3a) is greater than the number of the at least one second refrigerant flow channel (RF2) of the second outdoor unit heat exchanger (3b). The switching valve (4) is configured so as to switch between closing a first valve internal flow passage (VF1) and a third valve internal flow passage (VF3) and opening a second valve internal flow passage (VF2), and opening the first valve internal flow passage (VF1) and the third valve internal flow passage (VF3) and closing the second valve internal flow passage (VF2).
(FR) L'invention concerne un échangeur de chaleur d'unité extérieure (3) comprenant un premier échangeur de chaleur d'unité extérieure (3a), d'un second échangeur de chaleur d'unité extérieure (3b) et d'une soupape de commutation (4). Le nombre d'une pluralité de premiers canaux d'écoulement de fluide frigorigène (RF1) du premier échangeur de chaleur d'unité extérieure (3a) est supérieur au nombre d'au moins un second canal d'écoulement de fluide frigorigène (RF2) du second échangeur de chaleur d'unité extérieure (3b). La soupape de commutation (4) est configurée de manière à commuter entre la fermeture du premier passage d'écoulement interne de soupape (VF1) et du troisième passage d'écoulement interne de soupape (VF3) et l'ouverture d'un second passage d'écoulement interne de soupape (VF2)), et l'ouverture du premier passage d'écoulement interne de soupape (VF1) et du troisième passage d'écoulement interne de soupape (VF3) et la fermeture du second passage d'écoulement interne de soupape (VF2)
(JA) 室外機熱交換器(3)は、第1室外機熱交換器(3a)と、第2室外機熱交換器(3b)と、切替弁(4)とを備えている。第1室外機熱交換器(3a)の複数の第1冷媒流路(RF1)の数は、第2室外機熱交換器(3b)の少なくとも1つの第2冷媒流路(RF2)の数よりも多い。切替弁(4)は、第1弁内流路(VF1)および第3弁内流路(VF3)が閉じられるとともに第2弁内流路(VF2)が開かれるか、第1弁内流路(VF1)および第3弁内流路(VF3)が開かれるとともに第2弁内流路(VF2)が閉じられるかを切り替えるように構成されている。
