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： Disclosed is an air conditioning system for vehicles capable of operating control with a high degree of operating efficiency even in operating states wherein efficiency would be expected to decline, and while adhering to conventional control ideas. The air conditioning system for vehicles comprises a compressor that compresses a refrigerant; a condenser that condenses the compressed refrigerant; an expansion mechanism that expands the condensed refrigerant; an evaporator that evaporates the expanded refrigerant and brings the evaporated refrigerant into contact with air, cooling and dehumidifying the air; a blower that sends the air to the condenser; and a displacement control signal calculation means for determining a displacement control signal, using a displacement control signal calculation formula, which is to be inputted to the compressor from the outside. In the displacement control signal calculation means, a target air temperature at the evaporator exit is inputted, the displacement control signal is determined using the difference between the air temperature and the target air temperature at the evaporator exit when a displacement control signal calculated value is less than or equal to a predetermined value (A), and the displacement control signal is determined from the displacement control signal calculation formula when the displacement control signal calculated value is greater than the predetermined value (A).

摘要： An air conditioner for a vehicle comprises a refrigeration cycle including a variable displacement compressor for refrigerant which uses an engine as a drive source, a condenser, and an evaporator, a displacement adjustment means for outputting a displacement control signal to the compressor, and a compressor torque calculation means for calculating the torque of the compressor. The compressor torque calculation means includes at least two torque estimation means of a saturation region torque estimation means corresponding to a case where the compressor is driven at a maximum discharge displacement and a displacement control region torque estimation means corresponding to a case where it is driven at a discharge displacement other than the maximum discharge displacement, and also includes a correction means for correcting the calculation of the torque of the compressor when a change in engine rotational speed greater than a set value is detected. Even when the engine rotational speed changes rapidly, the torque of the compressor in the refrigeration cycle can be precisely calculated.
