Vehicle air-conditioning system

A vehicle air-conditioning system comprising:

• a compressor;
• a compressor inverter configured to vary the compressor capacity of the compressor to provide a predetermined air-conditioning level inside of a passenger compartment;
• a passenger compartment-external heat exchanger configured to exchange heat between outside air and refrigerant pumped by the compressor;
• a passenger compartment-internal heat exchanger configured to exchange heat between the refrigerant and air that is blown into the passenger compartment by an air blowing device;
• a thermal load detecting device configured to detect a thermal load of the compressor;
• a switching device configured to selectively delivery electrical power from one of a battery and an electric generating device to drive the compressor;
• and
• a control device configured to operate the switching device such that the electrical power to drive the compressor is delivered from the generating device when the thermal load detected by the thermal load detecting device is higher than a prescribed thermal load upon start up of the compressor.

A vehicle air-conditioning system comprising:

• refrigerant compressing means for supplying a compressed refrigerant;
• inverter means for varying compressor capacity of the refrigerant compressing means for providing a predetermined air-conditioning level inside of a passenger compartment;
• passenger compartment-external heat exchanger means for exchanging heat between outside air and refrigerant pumped by the refrigerant compressing means;
• a passenger compartment-internal heat exchanger configured to exchange heat between the refrigerant and air that is blown into the passenger compartment by an air blowing means;
• thermal load detecting means for detecting a thermal load of the compressor;
• and
• airflow rate correcting means for adjusting airflow rate in such a manner that the airflow rate delivered by the air blowing means decreases as the thermal load detected by the thermal load detecting means increases.
