Abstract
A refrigeration cycle device includes an exterior heat exchanger that includes a core portion including a stack of a plurality of tubes. The core portion has a first core portion, a second core portion and a third core portion each of which includes a tube group of the plurality of tubes. A flow direction of a refrigerant flowing through the second core portion in a heating operation is opposite to that in a cooling operation. Flow directions of the refrigerant flowing through the first core portion and the third core portion in the heating operation are same as those in the cooling operation.
