Abstract
(EN)
[Problem] To provide a vehicle air conditioning device that reliably cools a device which needs to be cooled and that can ensure a required heat absorption amount in a refrigerant circuit during a heating operation. [Solution] An accumulator 26 includes a heat exchanger 26f that exchanges heat between a refrigerant that circulates through a refrigerant circuit and a heat medium that circulates through a heat medium circuit. This configuration makes it possible to cool a battery connected to the heat medium circuit and to increase the heat absorption amount in the refrigerant circuit during the heating operation. Thus, a battery that requires cooling can be reliably cooled and a heat absorption amount required in the refrigerant circuit during the heat operation can be secured.

La présente invention aborde le problème de la réalisation d'un dispositif de climatisation pour véhicule qui refroidit de manière fiable un dispositif qui doit être refroidi et qui peut garantir une quantité d'absorption de chaleur exigée dans un circuit de fluide frigorigène pendant une opération de chauffage. La solution selon l'invention porte sur un accumulateur (26) comprenant un échangeur de chaleur (26f) qui échange de la chaleur entre un fluide frigorigène qui circule à travers un circuit de fluide frigorigène et un fluide caloporteur qui circule à travers un circuit de fluide caloporteur. Cette configuration permet de refroidir une batterie connectée au circuit de fluide caloporteur et d'augmenter la quantité d'absorption de chaleur dans le circuit de fluide frigorigène pendant l'opération de chauffage. Ainsi, une batterie qui nécessite un refroidissement peut être refroidie de manière fiable et une quantité d'absorption de chaleur exigée dans le circuit de fluide frigorigène pendant l'opération de chauffage peut être garantie.
