    摘要: A vapor-compression refrigerant cycle device includes an ejector, a first evaporator for evaporating refrigerant flowing out of a pressure-increasing portion of the ejector, a second evaporator for evaporating refrigerant to be drawn into a refrigerant suction port of the ejector. In the refrigerant cycle device, a refrigerant suction pipe is connected to a refrigerant outlet of the second evaporator and the refrigerant suction port of the ejector, and the surface of the refrigerant suction pipe is covered by an insulating member. Furthermore, the ejector, the first evaporator, the second evaporator and the refrigerant suction pipe are arranged in a passenger compartment of the vehicle.

    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: In an ejector cycle having an ejector for decompressing refrigerant, a check valve is disposed in an oil return passage through which refrigerant including a lubrication oil is introduced from a refrigerant outlet side of an evaporator to a refrigerant suction side of a compressor while bypassing the ejector. When the lubrication oil amount staying in the evaporator reduces, the check valve is automatically closed, and a normal operation mode of the ejector cycle is automatically set. On the contrary, when a large amount of lubrication oil stays in the evaporator, the check valve is automatically opened, and an oil return mode is automatically set. Therefore, the lubrication oil staying in the evaporator can be controlled equal to or lower than a predetermined amount, thereby effectively returning the lubrication oil to the compressor.

    摘要: A branch structure is provided on an upstream side of an ejector in a refrigerant cycle device, for branching and supplying refrigerant to a nozzle of the ejector and to an evaporator connected to a refrigerant suction port of the ejector. For example, the branch structure is constructed with an introduction pipe part for introducing the refrigerant, and at least two arm parts branched out from the introduction pipe part. The two arm parts are substantially symmetrical with respect to the introduction pipe part, while being positioned substantially under the same condition with respect to a direction of gravity.

    摘要: In an ejector cycle system, hot gas refrigerant discharged from a compressor is introduced into an evaporator through a bypass passage while bypassing an ejector and a gas-liquid separator in a defrosting operation for defrosting frost generated on the evaporator. In addition, a throttle or a check valve is provided in a refrigerant passage from the gas-liquid separator to a refrigerant inlet side of the evaporator. Accordingly, in the defrosting operation, the hot gas refrigerant from the compressor can be accurately introduced into the evaporator through the bypass passage without flowing toward the gas-liquid separator.
