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： 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： 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.
