摘要： In a refrigerant cycle system with an ejector pump, refrigerant to be introduced into a nozzle of the ejector pump is heated in a heat exchanger using waste heat from a vehicle engine as a heating source, and any one of a first mode, a second mode and a third mode can be selectively set based on a thermal load of an evaporator. In the first mode, refrigerant circulates from the evaporator toward a radiator only by the ejector pump. In the second mode, refrigerant circulate from the evaporator toward the radiator only by a compressor. Further, in the third mode, refrigerant circulates from the evaporator toward the radiator by using both the ejector pump and the compressor. Accordingly, the waste heat can be effectively recovered while a flow resistance of the refrigerant can be restricted.

摘要： In an ejector used for an ejector cycle system, a nozzle has a first refrigerant passage, a second refrigerant passage, and a third refrigerant passage in this order in a refrigerant flow direction from a refrigerant inlet toward a refrigerant outlet of the nozzle. The first refrigerant passage, the second refrigerant passage and the third refrigerant passage are formed into cylindrical shapes, respectively, each having a constant passage diameter. Further, a pressure increasing portion of the ejector is also formed into a cylindrical shape having a constant passage diameter. Accordingly, the ejector can be readily manufactured in low cost.

摘要： An ejector-type refrigerant cycle device includes: a first evaporator 15 that evaporates refrigerant flowing out of an ejector 14; a branch passage 17 that branches a flow of refrigerant between a radiator 13 and the ejector 14 and guides this flow of refrigerant to a vapor-phase refrigerant suction port 14c of the ejector 14; a throttling mechanism 18 disposed in the branch passage 17; and a second evaporator 19 disposed downstream of the throttling mechanism 18 with respect to the flow of refrigerant. The throttling mechanism 18 is constructed to be provided with a fully opening function, and to fully open the branch passage 17 when the second evaporator 19 is defrosted. Therefore, in an ejector-type refrigerant cycle device including multiple evaporators, the function of defrosting the evaporators can be carried out with a simple construction.

摘要： In an ejector, a nozzle includes a nozzle tapered section having an inner passage with a radial dimension reduced toward a nozzle outlet port, and a needle having a needle tapered section disposed in the inner passage. The needle tapered section has a cross sectional area reduced toward a downstream end of the needle, and the downstream end of the needle is positioned at a downstream side with respect to the nozzle outlet port. In addition, the nozzle tapered section has a taper angle (φ1) which is equal to or greater than a taper angle (φ2) of the needle tapered section. Therefore, a boundary face on the outside of a nozzle jet flow becomes in a balanced natural shape, and is controlled in accordance with an operating condition. Thus, the ejector cycle can be operated while keeping high efficiency, regardless of the thermal load of the ejector cycle.
