Abstract
(EN)
[Problem] To provide a vehicle air conditioner which can prevent battery failure caused by the battery becoming hot. [Solution] In a state in which the temperature Te of air cooled by a heat absorber 14 is controlled in air conditioning priority mode, if the temperature Tw of a heat medium detected by a heat medium temperature sensor 51 is greater than or equal to a prescribed temperature T1, then the temperature Tw of the heat medium cooled by a heat medium heat exchanger 24 is controlled in a battery cooling priority mode. In this way, because the state in which the battery B becomes hot can be suppressed, it becomes possible to reliably prevent failure of the battery B.

[Problème] Fournir un climatiseur de véhicule qui peut éviter une défaillance de batterie causée par la batterie devenant chaude. [Solution] Selon la présente invention, dans un état dans lequel la température Te de l'air refroidi par un absorbeur de chaleur 14 est régulée dans un mode de priorité de climatisation, si la température Tw d'un milieu chauffant détectée par un capteur de température de milieu chauffant 51 est supérieure ou égale à une température prescrite T1, alors la température Tw Du milieu chauffant refroidi par un échangeur de chaleur de milieu chauffant 24 est régulée dans un mode de priorité de refroidissement de batterie. De cette manière, étant donné que l'état dans lequel la batterie B devient chaude peut être supprimé, il devient possible d'empêcher de façon fiable une défaillance de la batterie B.

【課題】バッテリが高温になることによるバッテリの不具合の発生を防止することのできる車両用空気調和装置を提供する。 【解決手段】空調優先モードで吸熱器14によって冷却される空気の温度Teを制御している状態において、熱媒体温度センサ51によって検出された熱媒体の温度Twが所定の温度T1以上の場合に、バッテリ冷却優先モードで熱媒体熱交換器24によって冷却される熱媒体の温度Twを制御する。これにより、バッテリBが高温となる状態を抑制することができるので、バッテリBの不具合の発生を確実に防止することが可能となる。
