Abstract
(EN)
A first control voltage (Bv1) output to a blower (34) is set so as to increase with an increase in relatively low-temperature cooling water for an engine (10) that flows into a first heater core (31), and a second control voltage (Bv2) output to the blower (34) is set so as to increase with an increase in relatively high-temperature cooling water for the engine (10) that flows into a second heater core (32). The weighted mean of the first and the second control voltages (Bv1, Bv2) is determined on the basis of first and second flow rates of the cooling water flowing into the first and the second heater cores (31, 32), and used as an upper-limit value for a control voltage (Bv) that is actually output to the blower (34). Thus, blowing performance of the blower can be appropriately controlled in a vehicle air-conditioning apparatus provided with a plurality of heat exchangers for heating blowing air by using heating media of different temperature ranges as heating sources.
(FR)
Selon l'invention, une première tension de commande (Bv1) délivrée en sortie à une soufflante (34) est établie de façon à augmenter en fonction d'une augmentation d'une eau de refroidissement à température relativement basse pour un moteur (10), qui s'écoule dans un premier noyau d'élément chauffant (31), et une seconde tension de commande (Bv2) délivrée en sortie à la soufflante (34) est établie de façon à augmenter en fonction d'une augmentation d'une eau de refroidissement à température relativement élevée pour le moteur (10), qui s'écoule dans un second noyau d'élément chauffant (32). La moyenne pondérée de la première et de la seconde tensions de commande (Bv1, Bv2) est déterminée sur la base des premier et second débits d'écoulement de l'eau de refroidissement s'écoulant dans le premier et le second noyaux d'élément chauffant (31, 32), et est utilisée comme valeur de limite supérieure pour une tension de commande (Bv) qui est effectivement délivrée à la soufflante (34). Par conséquent, des performances de soufflage de la soufflante peuvent être commandées de façon appropriée dans un appareil de climatisation de véhicule comportant une pluralité d'échangeurs de chaleur pour chauffer de l'air de soufflage à l'aide de milieux de chauffage ayant des plages de température différentes constituant des sources de chauffage.
(JA)
第1ヒータコア(31)へ流入する比較的低温のエンジン(10)の冷却水の上昇に伴って、送風機(34)へ出力される第1制御電圧Bv1を増加させるように決定し、第2ヒータコア(32)へ流入する比較的高温のエンジン(10)の冷却水の上昇に伴って、送風機(34)へ出力される第2制御電圧Bv2を増加させるように決定する。さらに、第1、第2制御電圧Bv1,Bv2を、第1、2ヒータコア(31,32)へ流入する冷却水の第1、第2流量に基づいて重み付け平均し、実際に送風機(34)へ出力される制御電圧Bvの上限値とする。そのため、異なる温度帯の熱媒体を加熱源として送風空気を加熱する複数の加熱用熱交換器を備える車両用空調装置において、送風機の送風能力を適切に制御する。
