摘要:
An expansion-and-compressor device of a fluid machine has a pump mode operation in which the expansion-and-compressor device is rotated by a driving force from a driving source to compress working fluid, and a motor mode operation in which the fluid pressure is converted into energy of movement to output kinetic energy. The fluid machine further has a transmission device for transmitting the driving force from the driving source with increased rotational speed, when the expansion-and-compressor device is operated in the pump mode operation.

A control device is provided in a hybrid-driven auxiliary system using an engine and a motor as driving force. The control device includes: an auxiliary unit into which the motor is integrally assembled; current controlling means for controlling an electric current of the motor for driving or generating; current detecting means for detecting the electric current of the motor; and load torque computing means for computing, based on the electric current of the motor, a load torque when the auxiliary unit is operated.

A vehicle is provided with an air conditioning device that heats a passenger compartment, using cooling water passing through an internal combustion engine as a heat source, and a seat heater, which heats a seat in the passenger compartment by using an electric power from a battery as a heat source. An electronic control device performs EV travel of the vehicle by driving a motor generator while setting the internal combustion engine to a stop state and restarts the internal combustion engine when a cooling water temperature becomes equal to or less than a predetermined temperature during the EV travel. When a heating request is output to make the air conditioning device heat the passenger compartment during vehicle travel, the electronic control device reduces the heating degree of the air conditioning device and increases the heating degree by the seat heater during EV travel in comparison with non-EV travel.

A detector detects a remaining power of a battery. A calculator calculates a demand load of air-conditioning based on at least one of a preset temperature set for air in a passenger compartment of an electric vehicle and an outside temperature of air outside of the electric vehicle. A switching portion switches a mode of air-conditioning between a battery mode and an engine mode based on the calculated demand load and the detected remaining power of the battery. The battery mode causes the battery to supply electric power for air-conditioning, and the engine mode causes an engine of the electric vehicle to supply combustion energy for air-conditioning.

A refrigeration apparatus with an exhaust heat recovery device mounted on a vehicle includes a refrigeration cycle for allowing a refrigerant for refrigeration to circulate therethrough, and a Rankine cycle for allowing a refrigerant for the Rankine cycle to circulate therethrough. The Rankine-cycle condenser and the refrigeration-cycle condenser are disposed in predetermined positions of the vehicle in series with respect to a flow direction of external air for cooling, and the Rankine-cycle condenser is disposed on an upstream side of the external air with respect to the refrigeration-cycle condenser.

A complex fluid machine has an expansion-compressor device, a pump, and a motor generator, wherein the expansion-compressor device, the pump, and the motor generator are operatively connected and arranged in series. A portion of an outlet side passage formed in the fluid machine, through which the working fluid flows from the expansion device, is arranged adjacent to a portion of a pump outlet-side passage formed in the fluid machine, through which the working fluid flows from the pump, so that heat of the working fluid in the outlet side passage is transferred to the working fluid in the pump outlet-side passage. As a result, efficiency of Rankine cycle for collecting waste heat is increased.

A fluid pump includes a driving part, a movable part that is movable by power transmitted from the driving part via a transmission part, a fixed part disposed on a side of the movable part, opposite to the transmission part, to form an operating chamber having an outlet from which a fluid flowing into the operating chamber is pressure-fed to an outside in a liquid state by the movable part, and an introduction passage for introducing a part of the fluid in the operating chamber to the transmission part. Accordingly, the liquid fluid can be introduced to the transmission part such as a bearing through the introduction passage.

A waste heat energy recovery system has a refrigerant cycle and a Rankine cycle. When the cycle operation is changed from the refrigerant cycle to the Rankine cycle, an expansion device is started after the pump is started. When the cycle operation is changed from the Rankine cycle to the refrigerant cycle, the expansion device is stopped after the pump is stopped.

In a hybrid compressor device having a pulley 110, motor 120, compressor 130 and control unit 160, the respective rotary shafts 111, 121, 131 of the pulley 110, motor 120 and compressor 130 can be independently rotated, and these rotary shafts are connected to a speed change mechanism 150 by which a drive force can be transmitted from one rotary shaft 111 to the other remaining rotary shafts 121, 131 while the rotating speed is being changed. The motor 120 is composed of an IPM motor 120, in the rotor portion 120a of which permanent magnets 122 are arranged, and the speed change mechanism 150 is accommodated on the inner circumferential side of the rotor portion 120a. The control unit 160 adjusts a rotating speed of the motor 120, and the rotating speed of the compressor 130 can be increased and decreased with respect to the rotating speed of the pulley 110.
