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： The present invention has an object to provide an ejector cycle and an ejector, according to which a sufficient cooling performance can be obtained even when the input amount of the refrigerant to the ejector is decreased. A passage changeover means having a bypass channel is formed in an ejector. The passage changeover means opens the bypass channel in a bypass cooling operation, in which an input amount of the refrigerant to the ejector is decreased due to a low ambient temperature, and so on. Accordingly, in this bypass cooling operation, the refrigerant from an outside heat exchanger to the ejector bypasses an ejector nozzle and flows to an evaporator through the bypass channel.

摘要： An ejector refrigerant cycle device includes an ejector that has a nozzle portion for reducing pressure of refrigerant on a downstream side of a radiator to expand the refrigerant, and a refrigerant suction port from which refrigerant is drawn by a high-velocity refrigerant flow jetted from the nozzle portion, an evaporator that evaporates refrigerant and flows out the evaporated refrigerant to the refrigerant suction port, a flow amount changing unit that changes a refrigerant flow amount flowing into the evaporator, and a pressure abnormality detecting portion for detecting a pressure abnormality of a high-pressure refrigerant on an upstream side of the nozzle portion. In the ejector refrigerant cycle device, when the pressure abnormality detecting portion detects the pressure abnormality, the flow amount changing unit makes the refrigerant flow amount flowing into the evaporator larger than that in a normal pressure state of the high-pressure refrigerant.
