摘要： In an ejector cycle system using carbon dioxide as refrigerant, an ejector decompresses and expands refrigerant from a radiator to suck gas refrigerant evaporated in an evaporator, and converts an expansion energy to a pressure energy to increase a refrigerant pressure to be sucked into a compressor. Because refrigerant is decompressed and expanded in a super-critical area, a pressure difference during the decompression operation becomes larger, and a specific enthalpy difference becomes larger. Accordingly, energy converting efficiency in the ejector becomes higher, and efficiency of the ejector cycle system is improved.
摘要翻译：在使用二氧化碳作为制冷剂的喷射器循环系统中，喷射器将制冷剂从散热器减压并膨胀，以吸入在蒸发器中蒸发的制冷剂，并将膨胀能转化为压力能量，以增加要吸入压缩机的制冷剂压力。由于制冷剂在超临界区域减压膨胀，所以减压运转时的压差变大，比焓差变大。因此，喷射器中的能量转换效率变高，喷射器循环系统的效率提高。

摘要： In an ejector cycle with an ejector including a nozzle for decompressing refrigerant, a variable throttle device is disposed upstream from the nozzle to decompress and expand high-pressure refrigerant flowing from a condenser. For example, the variable throttle device decompresses the high-pressure refrigerant in a gas-liquid two-phase state at an upstream position from the nozzle of the ejector. In addition, the variable throttle device includes a back pressure chamber having an inner pressure that changes by sensing a refrigerant temperature at a refrigerant outlet side of an evaporator, and a pressure introducing means for introducing a refrigerant pressure of a refrigerant outlet side of the evaporator to a side opposite to the back pressure chamber with respect to a diaphragm. Therefore, a pressure difference between the back pressure chamber and the side opposite to the back pressure chamber can be made smaller.

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.

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： An ejector cycle with an ejector includes a nozzle for decompressing refrigerant. A receiver for storing refrigerant is disposed at a refrigerant outlet side of a condenser. A bypass passage and a switching valve for opening and closing the bypass passage are provided so that high-temperature refrigerant discharged from a compressor is introduced into an evaporator while bypassing the condenser in a defrosting operation. When the defrosting operation is set, the switching valve is opened while a fan for blowing cool air to the condenser is operated. A part of refrigerant discharged from the compressor flows into the evaporator to remove frost on a surface of the evaporator.
