Control of air conditioning for vehicle

Abstract

Abstract PURPOSE:To lower the operating rate of cooling mechanism by judging the adequateness of cooling ability on the basis of temperature inside or outside car room and the degree of target temperature. CONSTITUTION:A controller 10 is provided with an inside air temperature sensor 21 to produce an analog voltage signal according to the temperature of the inside of car room, an outside air temperature sensor 22 to produce an analog voltage signal according to the temperature of the outside of car room, an opening degree sensor 24 to produce an analog voltage signal according to the openign degree of the A/M damper 7, a temperature setter 23 to produce an analog voltage according to target temperature, and a switch panel 11 to produce an on-off signal by operation of switch groups for selecting operating mode. By electric command from said controller 10, a driving power from engine EG to cooling cycle CC is supplied intermittently by an electromagnetic valve 31, cooling water circulating path toa heater core 5 in heating cycle HC is opened or closed by an electromagnetic valve 32, and current applied to a blower motor 3 is altered according to the position of the damper 7 by a current-regulating mechanism 36.
