摘要: An ejector includes a nozzle for decompressing a fluid in any one state of a gas-liquid state, a liquid state and a super-critical state, and a body portion having a fluid suction port and a mixing and pressurizing portion. The ejector is provided with a suction passage through which a fluid drawn from the fluid suction port flows into the mixing and pressurizing portion. The suction passage is changed such that the fluid drawn from the fluid suction port is decompressed in the suction passage in iso-entropy. Alternatively, the suction passage is changed such that a flow velocity of the fluid flowing into the mixing and pressurizing portion from the suction passage is substantially equal to a flow velocity of the fluid flowing from a jet port of the nozzle into the mixing and pressurizing portion, or is equal to or larger than the sound velocity.

摘要: A body part of a decompression device has a swirl space for swirling a refrigerant that flows from a refrigerant inlet, and a refrigerant outlet that is positioned on an extension line of a swirl center line of the refrigerant and functions as a throttle. Further, a passage cross-sectional area of the refrigerant inlet is configured to be smaller than a twelve-fold value of a passage cross-sectional size of the refrigerant outlet, such that a swirl speed of the refrigerant in the swirl space is increased so as to enable a decompression boiling of the refrigerant around the swirl center line. In such manner, a gas-liquid mixture phase refrigerant securely flows into the refrigerant outlet, and it restricts a fluctuation of a flow amount of the refrigerant flowing toward a downstream side without complicating a cycle structure.

摘要: A refrigerant distributor includes a body portion defining a swirl space, a refrigerant inflow port, and first and second refrigerant outflow ports which causes refrigerant in the swirl space to flow out and distributes the refrigerant to components of a refrigeration cycle device. When a line connecting swirl centers of refrigerant swirling in the swirl space is taken as a swirl center line, the refrigerant swirls in the swirl space such at a velocity of a swirl flow that more vapor-phase refrigerant exists on an inner radius side than on an outer radius side and the velocity of swirl flow at the swirl center line on both end sides are different from each other. The first refrigerant outflow port is arranged at the one end side, and the second refrigerant outflow port is arranged at the other end side, on an extended line of the swirl center line.

摘要: A flow of refrigerant discharged from a first compressor and cooled by a radiator is branched by a first branch portion, and the branched refrigerant of one side is decompressed and expanded by a thermal expansion valve and is heat exchanged with the branched refrigerant of the other side in an inner heat exchanger. Therefore, the branched refrigerant of the other side supplied to the suction side evaporator and a nozzle portion of an ejector can be cooled, thereby improving COP. Furthermore, a suction port of a second compressor is coupled to an outlet side of the ejector so as to secure a drive flow of the ejector, and the refrigerant discharged from the second compressor and the refrigerant downstream of the thermal expansion valve are mixed to be drawn into the first compressor so that an ejector-type refrigerant cycle device can be operated stably.

摘要: An air conditioning system for a vehicle has a cool storage heat exchanger for continuing cooling operation with stored cooling energy during a compressor is stopped due to a temporal stop of an engine for the vehicle. Cooling energy is stored in the cool storage material of the cool storage heat exchanger during a normal cooling operation during which the compressor is operated by the engine. When the vehicle stops, for example before a traffic lamp, and thereby the compressor is not operated, an ejector is operated to circulate the refrigerant from the cool storage heat exchanger to an evaporator so that the cooling operation can be continued.
