PURPOSE:To improve the performance of the air conditoner including an engine drive compressor and to obtain a soft starting of the compressor by a method wherein the compressor is changed in the rotation speed steplessly by means of an electromagnetic joint type stepless speed change clutch in accordance with an engine speed, steam blowing temperature, passanger room temperature and the like. CONSTITUTION:The output signal of a temperature detector 12, the ignition pulse signal of an igniter 13 and the number of rotation of the compressor 2 are inputted into a controlling means 19. The controlling means 19, receiving this information mentioned above, controls the power supply to the steplessly speed-changing electromagnetic clutch 17 in accordance with the travelling speed of the vehicle and air cooling load. Accordingly, the compressor 2 is steplessly controlled in the rotation speed corresponding to the vehicle speed and the air cooling load, so that the passenger room temperature is maintained at a preset value. This construction eliminates the ON-OFF of the compressor, resulting in an improvement in COP (cooling performance/power consumption) and hence in a removal of discomfort caused by the change in the temperature of the blowing air. Further, the soft starting in the temperature of the blowing air. Further, the soft starting of the compressor 2 can be provided. |
