    摘要： In a vehicle air-conditioning device, refrigerant leakage is diagnosed precisely without any restrictions from an operating condition of the air-conditioning device. When the operating condition of the vehicle air-conditioning device is stable, a threshold value Th for determination of refrigerant leakage is set based on an outlet pressure Pd and an inlet pressure Ps of a compressor. Furthermore, a volume flow Gr in that refrigerant pipe running from a condenser to an expansion valve through which the refrigerant circulates in a liquid state is detected. When it is determined that the volume flow Gr exceeds the threshold value Th for determination of refrigerant leakage, a diagnosis result (alarm) indicating that the refrigerant leaks is output.

    摘要： An air conditioner for a vehicle uses a hybrid compressor (4) including a first compression mechanism driven by a first drive source (2) and a second compression mechanism driven by a second drive source (5), and a single discharge port connected to the first and the second compression mechanisms. The operation of the hybrid compressor is controlled by a controller (15) in accordance with a control mode. The controller has a first operation mode in which the first compression mechanism alone is driven, a second operation mode in which the second compression mechanism alone is driven, a third operation mode in which the first and the second compression mechanisms are simultaneously driven, and a fourth operation mode in which the first and the second compression mechanisms are simultaneously stopped. Depending upon various conditions, the controller selects, as the control mode, one of the first, the second, the third, and the fourth operation modes.

    摘要： A voltage polarity determination circuit includes an integration circuit, a switch, and a time measurement circuit. The integration circuit includes an operational amplifier circuit having an input offset voltage which is larger than the maximum value of a voltage input to the integration circuit or smaller than the minimum value of the input voltage of the integration circuit. The switch switches the input voltage of the integration circuit between a voltage whose polarity is to be determined and a reference voltage. The time measurement circuit measures a time interval which it takes for the output voltage of the integration circuit to reach a set voltage, and based on the result of the measurement, determines the polarity of the input voltage of the integration circuit.
