Abstract
(EN)
[Problem] To prevent cool defrosting while heating start-up control is performed by a vehicle air conditioner having two upper and lower layers. [Solution] An upper (lower) temperature-adjusting door (30A, 30B) is provided in an upper (lower) air passage (12A, 12B) between a cooling heat exchanger (26) and a heating heat exchanger (28) so as to adjust a first (second) bypass ratio, which is the ratio of the volume of air passing through an upper (lower) bypass pathway to the volume of air flowing from the upper (lower) portion of the cooling heat exchanger. During the heating start-up control, the upper and lower temperature-adjusting doors are positioned so that the first and second bypass ratios become substantially zero, and a defroster door (32D) is controlled so that the air flowing through a mixing chamber can pass through a defroster blowout passage (32). Then, when the temperature of the conditioned air supplied to the vehicle interior is gradually decreased with an increase in vehicle interior temperature, the upper and lower temperature-adjusting doors are controlled so that the second bypass ratio increases earlier than the first bypass ratio.

Le problème décrit par la présente invention est d'empêcher un dégivrage à froid tandis que la commande de démarrage de chauffage est réalisée par un climatiseur de véhicule comprenant deux couches supérieure et inférieure. La solution selon l'invention porte sur une porte supérieure (inférieure) de réglage de température (30A, 30B) qui est disposée dans un passage d'air supérieur (inférieur) (12A, 12B) entre un échangeur de chaleur de refroidissement (26) et un échangeur de chaleur de chauffage (28) de manière à régler un premier (second) rapport de dérivation, qui est le rapport entre le volume d'air passant à travers un trajet de dérivation supérieur (inférieur) et le volume d'air s'écoulant à partir de la partie supérieure (inférieure) de l'échangeur de chaleur de refroidissement. Pendant la commande de démarrage de chauffage, les portes supérieure et inférieure de réglage de température sont positionnées de sorte que les premier et second rapports de dérivation deviennent sensiblement nuls, et une porte de dégivrage (32D) est commandée de sorte que l'air s'écoulant à travers une chambre de mélange puisse traverser un passage de soufflage de dégivreur (32). Ensuite, lorsque la température de l'air climatisé fourni à l'intérieur du véhicule diminue progressivement avec une augmentation de la température intérieure du véhicule, les portes supérieure et inférieure de réglage de température sont commandées de sorte que le second rapport de dérivation augmente plus tôt que le premier rapport de dérivation.

【課題】上下二層式の車両用空調装置にて暖房起動制御を行う際のクールデフの防止 【解決手段】上(下)側温調ドア(30A,30B)が、冷却用熱交換器(26)と加熱用熱交換器(28)の間の上(下)側送風路(12A,12B)に設けられ、冷却用熱交換器の上(下)側部分から流出した空気量に対する上(下)側バイパス経路を通過する空気量の比率である第1(第2)迂回比率を調節する。暖房起動制御を行う際、第1及び第2迂回比率が共に実質的にゼロとなるように上側及び下側温調ドアを位置決めし、かつ、混合室を通流した空気がデフロスタ吹出通路(32)を通過できるようにデフロスタドア(32D)を制御し、その後、車室内温度の上昇に伴い車室内に供給される調和空気の温度を徐々に低下させてゆくときに、第2迂回比率が第1迂回比率よりも先に増加するように上側及び下側温調ドアを制御する。
