    Abstract: A refrigeration cycle device includes a first branch portion with branched first and second refrigerant passages, an ejector located in the first refrigerant passage, a first evaporator located in the first refrigerant passage to evaporate refrigerant flowing out of the ejector, a branch passage through which refrigerant upstream of a nozzle portion of the ejector flows into a refrigerant suction port of the ejector, a first throttle provided in the branch passage, a second evaporator located in the branch passage to evaporate the refrigerant flowing out of the first throttle, a second throttle provided in the second refrigerant passage, and a third evaporator located in the second refrigerant passage to evaporate the refrigerant flowing out of the second throttle. Furthermore, a pressure-loss generation portion is located to generate a pressure loss in the first refrigerant passage, thereby causing the refrigerant to easily flow into the second refrigerant passage.
