Abstract
(EN) Provided is a refrigeration cycle device for an automobile, which can effectively use different temperature regions of a heat exchanger created by using a zeotropic refrigerant mixture. The present invention is provided with a refrigerant circuit (10) which has an indoor heat exchanger (18) including a first indoor heat exchanger (16) and a second indoor heat exchanger (17), and in which a zeotropic refrigerant mixture circulates. The first indoor heat exchanger (16) and the second indoor heat exchanger (17) are arranged in series with each other in the flow of refrigerant in the refrigerant circuit (10). In the refrigerant flow direction when the first indoor heat exchanger (16) and the second indoor heat exchanger (17) are caused to function as refrigerant evaporators, the first indoor heat exchanger (16) is positioned upstream of the second indoor heat exchanger (17).
(FR) L'invention concerne un dispositif à cycle frigorifique destiné à une voiture particulière, qui peut utiliser efficacement différentes plages de température d'un échangeur de chaleur créées à l'aide d'un mélange de réfrigérant zéotropique. La présente invention est pourvue d'un circuit de réfrigérant (10) qui comporte un échangeur de chaleur interne (18) comprenant un premier échangeur de chaleur interne (16) et un second échangeur de chaleur interne (17), et dans lequel circule un mélange de réfrigérant zéotropique. Le premier échangeur de chaleur interne (16) et le second échangeur de chaleur interne (17) sont disposés en série l'un avec l'autre dans l'écoulement de réfrigérant dans le circuit de réfrigérant (10). Dans le sens d'écoulement de réfrigérant lorsque le premier échangeur de chaleur interne (16) et le second échangeur de chaleur interne (17) sont amenés à fonctionner comme évaporateurs de réfrigérant, le premier échangeur de chaleur interne (16) est positionné en amont du second échangeur de chaleur interne (17).
