PROBLEM TO BE SOLVED: To provide an air-conditioning system for vehicle in which fluctuations in an evaporator temperature is minimized and thus air-conditioning at a constant temperature level is enabled. SOLUTION: In this air-conditioning system, a dead zone as a standard for switching ON/OFF of a compressor 2 is stored in a non volatile memory constituting dead zone storage means. CPU, condition judgement means, judges whether a target air-blow temperature is lower than a set value or not, air-blow in a bent mode is selected or not, and an air-blow amount exceeds a set value or not. Only when all these are YES at the same time, resetting processing is executed for reducing a width of the temperature dead zone as a standard for switching, or a temperature sampling cycle. By reducing the width of the temperature dead zone and the temperature sampling cycle, the timing of the ON/OFF control of the compressor 2 is advanced. Therefore overshoot/ undershoot of a temperature of an evaporator 8 is reduced.
