PROBLEM TO BE SOLVED: To make a defrosting operation be hardly started during a heating operation and to improve efficiency of the heating operation by operating an ejector in order to solve such the problem that in the conventional refrigeration cycle device having the ejector and a plurality of heat exchangers, the heating operation stops due to switching, at the defrosting operation, to a cycle the same as a refrigeration cycle at the cooling operation.SOLUTION: In a refrigeration cycle device of the present invention, an outdoor heat exchanger comprises three heat exchangers. During low outdoor-temperature when frosting can easily occur, a cooling medium ejected from a diffuser flows in one of the heat exchangers, and a cooling medium sucked into a suction port flows in the other two heat exchangers. One of the two heat exchangers in which the cooling medium to be sucked flows is made to function as a heat radiator, and the other of the two heat exchangers is made to function as an evaporator, and thereby frosting is restrained. |
