Abstract
An air conditioning system for hybrid vehicles includes a control unit configured to re-operate an engine if an engine cooling water temperature is reduced to a lower limit value or less after entry into a motor drive mode, and configured to stop the engine if the engine cooling water temperature is increased to an upper limit value or more. The control unit is configured to change the upper limit value and the lower limit value depending on a target air injection temperature calculated according to an internal/external temperature condition and a user-set temperature so that, in the motor drive mode, a re-operation time point of the engine is actively changed according to the target air injection temperature.
