摘要： In a refrigerant cycle device with an ejector, a branch portion is located at an upstream side of a nozzle portion of the ejector so that the refrigerant flowing out of an exterior heat exchanger is branched into first and second streams in a cooling operation mode. A passage switching portion is configured such that the refrigerant of the first stream flows through the nozzle portion of the ejector, and the refrigerant of the second stream flows through the decompression unit, the using-side heat exchanger, and the refrigerant suction port of the ejector, in the cooling operation mode. In contrast, the refrigerant discharged from the compressor flows into the nozzle portion after passing through the using-side heat exchanger, and the refrigerant flowing out of the exterior heat exchanger flows into the refrigerant suction port of the ejector, in the heating operation mode.

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： In an ejector cycle device having an ejector, an evaporator is arranged in a refrigerant branch passage connected to a refrigerant suction port of the ejector, an opening/closing member for opening and closing a refrigerant passage is disposed to prevent refrigerant from flowing into the evaporator, and a control unit intermittently controls operation of the compressor. In the ejector cycle device, the control unit brings the opening/closing member into a closing state in a time period for which the operation of the compressor is stopped. Accordingly, it can restrict liquid refrigerant from collecting in the evaporator while the compressor is stopped.

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.
