    摘要: In an ejector, a refrigerant passage of a nozzle for decompressing and expanding refrigerant includes a throat portion in which a refrigerant passage sectional area is most reduced, a first taper portion arranged downstream of the throat portion to gradually enlarge the refrigerant passage sectional area, a second taper portion arranged downstream of the first taper portion to gradually enlarge the refrigerant passage sectional area, and an end taper portion arranged in a range from an outlet side of the second taper portion to a refrigerant jet port to gradually enlarge the refrigerant passage sectional area. Furthermore, a second expanding angle at the outlet side of the second taper portion is larger than the first expanding angle at the outlet side of the first taper portion, and an end expanding angle at the outlet side of the end taper portion is smaller than the second expanding angle.

    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 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: A vapor compression refrigerating cycle apparatus includes a compressor, a radiator, first and second throttle devices, a flow distributor, an ejector, a suction passage, and first and second evaporators. The flow distributor separates refrigerant decompressed through the first throttle device into a first passage and a second passage. The first passage is in communication with a nozzle portion of the ejector. The second passage is in communication with a suction portion of the ejector through the suction passage. The second throttle device and the second evaporator are disposed on the suction passage. The flow distributor is configured to be capable of adjusting a ratio of a flow rate of refrigerant passing through the second passage to a flow rate of refrigerant passing through the first passage in accordance with a heat load of at least one of the radiator, the first evaporator and the second evaporator.
