摘要： After the tooth portion 102b of the stationary scroll 102 and the tooth portion 103b of the revolving scroll 103 have contacted each other on one contact face 121 in the central portion of the scroll (shown in FIG. 5A), when this contact face 121 is shifted to two sliding contact portions 122, 123, the operating chamber V is formed between the two sliding contact portions 122, 123 (shown in FIG. 5B), and the refrigerant introducing port 105a is open to the region on the contact face 121. Accordingly, the operating chamber can be instantaneously changed over while the sealing property is ensured. Due to the above structure, the sealing property for suppressing leakage from the high pressure side at the time of the expansion mode can be compatible with the smoothing property for smoothing a change-over of the scroll operating chamber successively formed.

摘要： An oil separator includes a separation part and an oil storage part. The separation part includes a separation cylinder, an inner cylinder disposed in the separation cylinder and an inlet pipe connecting to the separation cylinder tangential to an inner surface of the separation cylinder. The separation part defines an inlet opening to introduce CO2 refrigerant containing oil in the separation cylinder. The separation cylinder separates the oil from the CO2 refrigerant by means of centrifugal force. A ratio of a flow rate (kg/h) of the CO2 refrigerant flowing in the separation cylinder to an area (mm2) of the inlet opening is at least 4. Alternative to or in addition to the above, a ratio of a distance (mm) from an end of the inner cylinder to a bottom wall of the separation cylinder to an inner diameter (mm) of the separation cylinder is at least 2.5.

摘要： A vapor-compression refrigerant cycle system with a refrigeration cycle and a Rankine cycle includes a compressor, a radiator, a gas-liquid separator, a decompression device and an evaporator. In the vapor-compression refrigerant cycle system, a liquid pump is disposed for supplying the liquid refrigerant in the gas-liquid separator to a heater for heating the refrigerant, a cooling means is provided for cooling the liquid refrigerant to be sucked into the liquid pump, and an energy recovery unit for expanding the refrigerant flowing out of the heater is disposed to recover thermal energy in the refrigerant from the heater. When the Rankine cycle is set so that the energy recovery unit recovers the thermal energy, the cooling means cools the liquid refrigerant to be sucked into the liquid pump. Therefore, pumping efficiency of the liquid pump can be effectively improved.

摘要： The waste heat recovering operation mode (a Rankine cycle) is started and operated for a predetermined period of time T1 (s) (S430 to S450). In the case where the difference (P2−P1) between the upstream pressure P1 and the downstream pressure P2 of the liquid pump is higher than the predetermined pressure P, the waste heat recovering operation mode is continued. In the case where the difference (P2−P1) is not more than the predetermined pressure P, after the air conditioning mode is started (S480 to S500), the waste heat recovering operation mode is started again (S430 to S450). Due to the foregoing, it is possible to provide a heat cycle, which is provided with a refrigerating cycle and a Rankine cycle which are changeable each other, in which an incomplete start at the time of Rankine cycle can be reduced and a deterioration of the cycle efficiency can be reduced.

摘要： In a refrigerant cycle system, refrigerant compressed in a first compressor is cooled and condensed in a radiator, and refrigerant from the radiator branches into main-flow refrigerant and supplementary-flow refrigerant. The main-flow refrigerant is decompressed in an expansion unit while expansion energy of the main-flow refrigerant is converted to mechanical energy. Thus, the enthalpy of the main-flow refrigerant is reduced along an isentropic curve. Therefore, even when the pressure within the evaporator increases, refrigerating effect is prevented from being greatly reduced in the refrigerant cycle system. Further, refrigerant flowing into the radiator is compressed using the converted mechanical energy. Thus, coefficient of performance of the refrigerant cycle system is improved.

摘要翻译： 在制冷剂循环系统中，在第一压缩机中压缩的制冷剂在散热器中冷却冷凝，来自散热器的制冷剂分支成主流制冷剂和辅助流动制冷剂。 主流制冷剂在膨胀单元中减压，主流制冷剂的膨胀能转化为机械能。 因此，主流制冷剂的焓沿着等熵曲线减小。 因此，即使当蒸发器内的压力增加时，制冷剂循环系统也不会大大降低制冷效果。 此外，流入散热器的制冷剂使用转换后的机械能进行压缩。 因此，制冷剂循环系统的性能系数提高。

摘要： A heat pump cycle system which can switches cooling operation and heating operation for a compartment includes a first inside heat exchanger and a second inside heat exchanger disposed in an air conditioning case. The first inside heat exchanger is disposed in the air conditioning case at a downstream air side of the second inside heat exchanger, while being arranged in line in a flow direction of refrigerant. The first inside heat exchanger is upstream from the second inside heat exchanger in the flow direction of refrigerant during the heating operation. In the heat pump cycle system, an expansion valve is controlled so that coefficient of performance in each operation becomes approximately maximum. Thus, during the heating operation of the heat pump cycle system, a lower limit temperature of air blown from the inside heat exchangers can be increased so that temperature of air blown into the compartment is increased, while the coefficient of performance is improved.

摘要： An object of the invention is to provide a rankine cycle suitable for a use for a motor vehicle. In a waste heat collecting system having the rankine cycle and a refrigerating cycle, when ECU receives an air-conditioning signal from A/C ECU, the refrigerating cycle is operated, by preceding the operation of the rankine cycle. In the case that there is no air-conditioning signal and a temperature of an engine cooling water is higher than a predetermined value, the rankine cycle is operated.
