摘要： An air conditioning apparatus includes an electric compressor, an inverter, a temperature detection element, and an ECU. The electric compressor compresses a refrigerant drawn from a refrigerant intake port and discharges the refrigerant from a refrigerant discharge port. The inverter is integrated with the electric compressor so as to be cooled by the drawn refrigerant, and operates the electric compressor according to a control signal. The temperature detection element detects a temperature of the inverter. The ECU outputs a control signal to control the inverter. The ECU performs any one or both of a control for reducing a self-cooling amount of the electric compressor and a control for increasing a self-heat generation amount of the inverter with respect to the inverter when the temperature detected by the temperature detection element is lower than a predetermined reference temperature.

摘要： The present invention makes it possible to integrate and control in one circuit the systems, such as electric power components, a driving motor, a stack, and an AC condenser which have the maximum enthalpy under similar operational temperature and use conditions, by using an integrated radiator. Therefore, it is possible to minimize air-through resistance of the radiator for cooling the stack and the electric power components and ensure smooth and stable cooling performance of the stack, electric power components, and AC condenser while improving fuel efficiency by reducing the condensation pressure of the air conditioner. Further, it is possible to improve cooling efficiency by non-repeatedly arranging heat exchangers, and reduce the weight of a vehicle, volume of the parts, and the manufacturing cost, by avoiding using too many parts, such as a radiator, a water pump, and a reservoir tank.

摘要： When the magnitude of a motor current Iu is smaller than a threshold value at a timing when a polarity of the motor current Iu is expected to be reversed after the elapse of one control cycle, a control device sets a correction amount of a width of a pulse generated by PWM control at a correction amount +α. When the magnitude of the motor current is greater than the threshold value at the timing, the control device sets the correction amount of the width of the pulse generated by the PWM control at zero or a value β smaller than the correction amount +α. As a result, an error of a dead time period in inverter control can be reduced.
