Abstract

When a refrigerant flow-path switch performs switching to a first refrigerant flow path, an interior condenser heating air blown into an interior as a first temperature-adjustment subject and an auxiliary heat exchanger are connected in parallel, and the auxiliary heat exchanger heats air blown to a battery as a second temperature-adjustment subject. In contrast, when the refrigerant flow-path switch performs switching to a second refrigerant flow path, an interior evaporator cooling air blown into the interior and the auxiliary heat exchanger are connected in parallel, and the auxiliary heat exchanger cools the air blown to the battery. With this arrangement, one common auxiliary heat exchanger can cool or heat the air for the battery, thereby leading to reduction in size of an entire refrigeration cycle device.
