摘要： A unit for an ejector-type refrigeration cycle includes an ejector, first and second evaporators connected in parallel to a downstream side of the ejector and configured to evaporate the refrigerant discharged from the outlet of the ejector, and a refrigerant distributor configured to distribute the refrigerant discharged from an outlet of the ejector to a side of the first evaporator and a side of the second evaporator. The ejector draws refrigerant from a refrigerant suction port by a high-velocity refrigerant flow jetted from a nozzle portion, and mixes the refrigerant injected from the nozzle portion with the refrigerant drawn from the refrigerant suction port so as to discharge the mixed refrigerant from the outlet of the ejector. The ejector and the refrigerant distributor are connected to each other such that the refrigerant discharged from the outlet of the ejector directly flows into the refrigerant distributor.

摘要： In a vapor compression refrigeration system, an evaporator and a gas-liquid separator are received in a common casing, so that the gas-liquid separator and the evaporator are placed close to each other. Thus, it is possible to limit heat absorption of the liquid phase refrigerant from the atmosphere to reduce the heat loss upon discharge of the refrigerant from the gas-liquid separator. Also, it is possible to reduce pressure loss in a refrigerant passage between the gas-liquid separator and the evaporator.

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, 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.
