PURPOSE:To provide an efficient power-consumption distribution and a stable temperature control in a vehicle by controlling the power supplied for the electric ventilating means and the temperature controlling amount of the temperature controlling means by using the input signal of the air-conditioning controller and the operating condition signal of the vehicle electric load. CONSTITUTION:Data signals from an internal-air temperature sensor 21, an external-air temperature sensor 22, a temperature setting 23, an opening-amount sensor 24 of a temperature controlling damper 7, a headlight switch 25, a wiper switch 26 and a switch panel 11 are inputted to a controller 10 to arithmetically process according to a given program. Then, the electrical command signals, which are outputted through the processing, control a solenoid clutch 31 controlling the driving force from an engine EG to a cooling cycle CC, a solenoid valve 32 opening and closing the cooling water circulating passage, and suction-pressure actuators 33-35 operating dampers 2, 7 and 8 by using the engine suction-pressure. This provides a comprehensive control including the operating conditions of the electric loads, so that the power consumption can be efficiently distributed and the internal temperature is stabilized.
