    • A heat exchanger unit includes first and second plate heat exchangers disposed in series along a refrigerant flow direction. A refrigerant flows from the first plate heat exchanger to the second plate heat exchanger when the heat exchanger unit operates as an evaporator to heat the refrigerant, and the refrigerant flows from the second plate heat exchanger to the first plate heat exchanger when the heat exchanger unit operates as a condenser to cool the refrigerant. The first and second plate heat exchangers have first and second gas-liquid mixing structures to promote gas-liquid mixing of the refrigerant when the heat exchanger unit heats the refrigerant. The first and second gas-liquid mixing structures are configured such that pressure loss becomes larger when the gas-liquid mixing action becomes higher and such that the gas-liquid mixing action of the first gas-liquid mixing structure is higher than the gas-liquid mixing action of the second gas-liquid mixing structure.

    • A control system for an induction motor of the present invention independently commands the torque current component and the exciting current component of a stator current group supplied to the stator of an induction motor so as to feed-back control the amplitude and phase of the stator current group. The torque current component is commanded to control the output torque of the induction motor in correspondence with the output of a steering force sensor for detecting the steering force. According to an electric power steering apparatus using an induction motor controlled by the control system, a permanent magnet is not used for the motor so additional equipment such as a clutch is not required. Consequently, the structure can be simplified and the size of the unit can be reduced. Further, manual steering operation can be performed in the case of failure.
    • 本发明的感应电动机的控制系统独立地指定提供给感应电动机的定子的定子电流组的转矩电流分量和励磁电流分量,以便反馈控制定子电流的振幅和相位 组。 命令转矩电流分量与感应转向力的转向力传感器的输出对应地控制感应电动机的输出转矩。 根据使用由控制系统控制的感应电动机的电动助力转向装置,永磁体不用于电动机,因此不需要诸如离合器的附加设备。 因此,可以简化结构,并且可以减小单元的尺寸。 此外,在故障的情况下可以执行手动转向操作。
