PURPOSE:To restrict the compressor load at the start in order to reduce electric power consumption by installing a bypass circuit provided with a switching means, making a detour around a compressor, and by opening the bypass circuit several seconds before the start of the air-conditioner and by closing it several seconds after the start. CONSTITUTION:When car running conditioner changes from power-driving to inertia-running, a driving motor of the car stops and a switch 7 is turned on to operate a timer 8. Next, several seconds later, a solenoid switch 12 is turned off via a relay 10 to close a solenoid valve 18, while a solenoid switch 19 is turned on via a relay 15 in order to start a compressor 1. Next, when the car running condition changes from inertia-running to either stopping via braking or renewed power-driving or when the driving motor of the car restarts, the switch 7 turns off to open the solenoid valve 18. And a solenoid valve 16 is opened via a relay 14, while operation of a timer 9 opens a solenoid switch 13 via a relay 11 several seconds later. Thus, the relay 15 is demagnetized and the compressor 1 stops. |
