Abstract: A body part of a decompression device is provided with a swirling space that allows a refrigerant from a refrigerant inlet to swirl, a throttle space that depressurizes the refrigerant that has flowed out of the swirling space, and a downstream-side space that is disposed on the downstream side of the throttle space in a refrigerant flow and is formed so that the pressure of a refrigerant present in the downstream-side space becomes uniform.

Abstract: In a dehumidification-air heating mode, a refrigerant circuit is configured such that a refrigerant outlet side of an exterior heat exchanger communicates with a heating side refrigerant suction port of a heating side ejector as a refrigerant decompression means, and that a refrigerant inlet side of an interior evaporator communicates with an outlet side of a heating side diffuser of the heating side ejector. A refrigerant evaporation temperature in the exterior heat exchanger is set lower than that of the interior evaporator by a pressurizing effect of the heating side ejector. Thus, the amount of heat absorption by the refrigerant at the exterior heat exchanger is increased to improve the heating capacity of the air in an interior condenser.
Abstract translation: 在除湿空气加热模式中，制冷剂回路被构造成使得外部热交换器的制冷剂出口侧与作为制冷剂减压装置的加热侧喷射器的加热侧制冷剂吸入口连通，制冷剂入口侧 内部蒸发器与加热侧喷射器的加热侧扩散器的出口侧连通。 通过加热侧喷射器的加压效应，将外部热交换器的制冷剂蒸发温度设定为低于内部蒸发器的制冷剂蒸发温度。 因此，外部热交换器中的制冷剂的吸热量增加，以提高内部冷凝器中的空气的加热能力。

Abstract: A mixing portion that mixes an injection refrigerant and a suction refrigerant is formed in a range of an internal space of a heating-side body portion of a heating-side ejector from a refrigerant injection port of a heating-side nozzle portion to an inlet of a heating-side diffuser. Further, the mixing portion is formed in a shape that gradually decreases a refrigerant passage area toward a downstream side of a refrigerant flow, and a refrigerant passage area of the inlet of the heating-side diffuser is set smaller than that of the refrigerant injection port. Thus, the flow velocity of the mixed refrigerant is decelerated to a value lower than a two phase sound velocity within the mixing portion, thereby suppressing occurrence of shock wave in the heating-side diffuser and stabilizing the pressure increasing performance in the heating-side diffuser.
