    • A refrigerant cycle device includes a branch portion for branching a flow of refrigerant discharged from a compressor, a first radiator for radiating one high-temperature and high-pressure refrigerant branched at the branch portion, an ejector including a nozzle portion for decompressing refrigerant on a downstream side of the first radiator, a second radiator for radiating the other high-temperature and high-pressure refrigerant branched at the branch portion, a throttle device for decompressing refrigerant on a downstream side of the second radiator, and a suction side evaporator for evaporating refrigerant downstream of the throttle device and for allowing the refrigerant to flow to an upstream side of a refrigerant suction port of the ejector. Furthermore, the first and second radiators are disposed downstream of the branch portion such that a heat radiation amount of refrigerant in the first radiator is smaller than that in the second radiator.
    • 一种制冷剂循环装置,包括用于分流从压缩机排出的制冷剂流的分支部分,用于辐射在分支部分分支的一个高温和高压制冷剂的第一辐射器,包括用于在制冷剂上减压制冷剂的喷嘴部分的喷射器 第一散热器的下游侧,用于照射在分支部分分支的其他高温高压制冷剂的第二散热器,用于在第二散热器的下游侧减压制冷剂的节流装置和用于蒸发的吸入侧蒸发器 制冷剂在制冷剂吸入口的上游侧流动。 此外,第一和第二散热器设置在分支部分的下游,使得第一散热器中的制冷剂的散热量小于第二散热器中的制冷剂的散热量。
