    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: A fluid machine for a gas compression refrigerating system comprises a first and a second working for performing a pump mode operation, in which working fluid of low pressure is sucked into and compressed by the working chambers. The fluid machine further comprises valve mechanism for selectively forming a motor mode passage in combination with a fluid passage change-over device, so that super heated working fluid of high pressure is introduced into at least one of the working chambers to perform a motor mode operation, in which the high pressure working fluid is expanded in the working chamber to obtain mechanical energy. The fluid machine according to the invention, therefore, performs the pump mode operation at one of the working chambers and at the same time the motor mode operation at the other working chamber.

    摘要: Power generated by an alternator 2 and power generated by an electric motor 12 are controlled such that a power generation amount of either the alternator 2 or the electric motor 12, whichever has a higher power generation efficiency, becomes larger than a power generation amount of either the alternator 2 or the electric motor 12, whichever has a lower power generation efficiency. Consequently, power needed for power generation, that is, power consumed by an engine 1 can be decreased, thereby making it possible to improve the fuel economy of a vehicle.

    摘要: A fluid machine according to the present invention has an expansion-and-compressor device selectively operating as an expansion device for collecting waste heat from an internal combustion engine and converting the collected heat energy into mechanical rotational force, and as a compressor device for compressing refrigerant for a refrigerating cycle for air conditioner. The fluid machine further comprises an electric rotating device selectively operating as an electric power generator and as an electric motor. A power transmission device is further provided between the expansion-and-compressor device and the electric rotating device for selectively transmitting the rotational force from the expansion-and-compressor device to the electric rotating device and vice versa. The power transmission device is composed of a planetary gear train so that it can change rotational speed to be transmitted to the expansion-and-compressor device or to the electric rotating device. Accordingly, the expansion-and-compressor device as well as the electric rotating device can be operated at their most efficient rotational speed.

    摘要: An object of the invention is to minimize energy loss to be generated at a driving shaft and a shaft seal device, when an electric rotating device is driven by an expansion-and-compressor device. According to a feature of the invention, a first driving shaft is rotationally supported by a housing and transmits a driving force from an engine to a second shaft of the expansion-and-compressor device, wherein a shaft seal device is provided on the first driving shaft for air-tightly sealing the inside of the housing from the outside of the housing. A power transmission control device (electromagnetic clutch or one way clutch) is operatively provided in a path between the first driving shaft and the second shaft, so that power transmission from the second shaft to the first driving shaft is cut off, to suppress any energy loss to be generated between the first driving shaft and the shaft seal device.
