摘要： An air conditioning system for a vehicle includes a compressor driven by a first drive source or a second drive source, or a combination thereof, and an evaporator operationally connected to the compressor via a refrigerant circuit. The system also includes a blower for dispensing air into an interior of the vehicle via the evaporator. The blower is driven by the first drive source or the second drive source, or a combination thereof. Moreover, the system includes a controller for controlling the first drive source and the second drive source. Specifically, when a temperature of air dispensed from the evaporator is greater than a predetermined temperature and a speed of the vehicle is greater than a predetermined speed, the first drive source drives the compressor and the blower. Moreover, when the temperature of air dispensed from the evaporator is greater than the predetermined temperature, the speed of the vehicle is less than the predetermined speed, and a voltage of a power source of the second drive source is less than or equal to a predetermined voltage, the compressor is inactive and the second drive source drives the blower.

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.
