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： An electric compressor having a compression unit and an electric motor is mounted to a vehicle through a first support member supporting the compression unit and a second support member supporting the motor. A spring constant of the first support member is smaller than that of the second support member. Therefore, vibration of the compression unit is absorbed by the first support member, and is restricted from being transmitted to the vehicle. On the other hand, vibration of the vehicle is absorbed by the second support member, and is restricted from being transmitted to the compressor. As a result, inlet and outlet pipes connected to the compressor are insulated from a large amount of stress and therefore are not broken due to fatigue at an early stage.

摘要： A heat pump air conditioner has a heat exchanger, a separator for separating refrigerant discharged from the heat exchanger into gas refrigerant and liquid refrigerant, and a compressor. Gas refrigerant in the separator is sucked into the compressor through a gas suction pipe. Oil-dissolved liquid refrigerant in the separator is also sucked through an oil return hole formed at a bottom of the gas suction pipe into the compressor. At the time of starting the air conditioner, when it is judged that a surface of liquid refrigerant in the separator is rapidly lowered to the oil return hole, a rotational speed of the compressor is controlled so that an amount of refrigerant discharged from the compressor is decreased. As a result, the surface of liquid refrigerant is kept higher than the oil return hole, and oil shortage of the compressor is restricted.

摘要： A gas-injection type refrigeration-cycle device has heat exchanger where refrigerant extracts waste heat from heating devices. In the refrigeration-cycle device, the mode is changed between where lower-pressure refrigerant extracts heat and where intermediate-pressure refrigerant extracts the heat of the hot water. The lower-pressure refrigerant is drawn into compressor, after heat exchanger is set at the lower-pressure side of the refrigeration cycle. The intermediate-pressure refrigerant is introduced into compressor-gas-injection port, after heat exchanger is set at the intermediate-pressure side of the refrigeration cycle. In another aspect, a defrosting mode of outdoor heat exchanger includes a heating mode, and gas refrigerant discharged from compressor flows through condenser without heat exchange. Thereafter, the flow of the gas refrigerant is divided to two portions, and the gas refrigerant of one portion flows into outdoor heat exchanger, thereby defrosting outdoor heat exchanger. The other portion flows into evaporator, thereby heating blown air within an air-conditioning duct by evaporator.

摘要： A refrigerant cycle system includes a gas-liquid separator for separating gas-liquid refrigerant into gas refrigerant and liquid refrigerant. The gas-liquid separator has a liquid-suction pipe for introducing liquid refrigerant from the gas-liquid separator to a decompressing unit, and a gas-suction pipe for introducing gas refrigerant from the gas-liquid separator to a compressor. The gas-suction pipe has a suction hole for sucking liquid refrigerant therein, and the suction hole is provided at a position lower than an open end of the liquid-suction pipe. Because a height of a surface of liquid refrigerant in the gas-liquid separator is constantly equal to or higher than the open end of the liquid-suction pipe regardless of change in a heating load of the refrigerant cycle, liquid refrigerant is constantly sucked into the gas-suction pipe from the suction hole. Thus, liquid refrigerant in which lubricating oil is dissolved can be constantly introduced into the compressor, thereby preventing shortage of lubricating oil in the compressor. On the other hand, in the refrigerant cycle, an oil-discharging mode is selectively set at a starting time of a heating mode so that lubricating oil staying in an evaporator is discharged. Therefore, lubricating oil is sufficiently returned to the compressor even when the heating mode is switched from a cooling mode.

摘要翻译： 制冷剂循环系统包括用于将气液制冷剂分离成气体制冷剂和液体制冷剂的气液分离器。 气液分离器具有用于将液体制冷剂从气 - 液分离器引入减压单元的吸液管，以及用于将气液制冷剂从气 - 液分离器引入压缩机的吸气管。 吸气管具有用于吸入液体制冷剂的吸入孔，吸入孔设置在比吸液管的开口端低的位置。 由于气液分离器中的液体制冷剂的表面的高度恒定地等于或高于吸液管的开口端，而与制冷剂循环的加热负荷的变化无关，液态制冷剂被不断地吸入 吸气管从吸气孔。 因此，可以将压缩机内的润滑油溶解的液体制冷剂恒定地引入压缩机中，防止压缩机中的润滑油不足。 另一方面，在制冷剂循环中，在加热模式的开始时刻选择性地设定排油模式，从而排出滞留在蒸发器中的润滑油。 因此，即使在从制冷模式切换加热模式的情况下，也能够将润滑油充分返回压缩机。

摘要： The invention prevents the temperature of supplied air from being decreased by a defrosting operation when a vehicle is in operation. During the heating operation, it is judged whether the vehicle is in operation. When the vehicle is in operation, it is judged whether an external heat exchanger is frosted or not relying upon the external air temperature, temperature of the external heat exchanger (coolant) and the time of heating operation. When it is judged that frost is formed, the rotational speed of the compressor is increased to increase the ability to supplying the coolant, to maintain heating ability and to prevent the drop of temperature of the supplied air. When the frost is formed after the operation of the vehicle has been finished, it is judged whether the secondary batteries are being charged or not, i.e., whether the charging circuit of the secondary batteries is connected to the external power source for charging or not. When it has not been connected, the device waits until it is connected, and the defrosting operation is executed at a moment when the charging circuit is connected.

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 outer surface of a cold-storage container (or a refrigerant tube) is provided with a plurality of protrusion portions or recess portions. A cooling air passage, in which air flows to cool a space to be cooled in a cold storage time and in a cold release time of the cold storage material, is provided to contact a surface of the refrigerant tube on a side opposite to the cold storage container bonded to the refrigerant tube. The refrigerant tubes and the cold storage container form therebetween a cold-storage side air passage by the protrusion portions or the recess portions, such that air flows in the cold-storage side air passage separated from the cooling air passage. For example, the cold-storage side air passage is provided with a slanting space that causes condensed water or ice generated in the cold storage time to be drained along the cold-storage side air passage.

摘要： In the context of the early detection and monitoring of eye diseases, such as glaucoma and diabetic retinopathy, the use of optical coherence tomography presents the difficulty, with respect to blood vessel segmentation, of weak visibility of vessel pattern in the OCT fundus image. To address this problem, a boosting learning approach uses three-dimensional (3D) information to effect automated segmentation of retinal blood vessels. The automated blood vessel segmentation technique described herein is based on 3D spectral domain OCT and provides accurate vessel pattern for clinical analysis, for retinal image registration, and for early diagnosis and monitoring of the progression of glaucoma and other retinal diseases. The technique employs a machine learning algorithm to identify blood vessel automatically in 3D OCT image, in a manner that does not rely on retinal layer segmentation.
