Abstract
An outdoor heat exchanger is installed in a refrigerant circuit and has a heat exchange core portion providing refrigerant flow paths different in a cooling operation and a heating operation. A flow path switching device switches the flow path of the refrigerant in the heat exchange core portion of the outdoor heat exchanger between a cooling mode flow path during the cooling operation and a heating mode flow path during the heating operation. The refrigerant flows down in one direction in the heating mode flow path. The refrigerant flows in one direction and then flows down in an opposite direction in the cooling mode flow path.
