PROBLEM TO BE SOLVED: To adequately perform cooling while preventing the deterioration of the stopping efficiency of an engine, when an economy running control such as an automatic idling stop control is performed. SOLUTION: When an engine stop condition is satisfied and the engine is stopped, it is determined whether refrigerant pressure is a set pressure or higher and whether a temperature of engine cooling water a set temperature or higher. At a predetermined speed or lower with a fan motor stopped, the fan motor is operated when the pressure exceeds the set pressure or the temperature exceeds the set temperature (steps 100 to 120). At a predetermined speed or higher or in a state that the fan motor is driven, an engine start request is performed to stop the fan motor when the pressure exceeds the set pressure or the temperature exceeds the set temperature, and the engine start request is canceled when the coolant pressure is lower than the set pressure and the water temperature is lower than the set temperature (steps 114 to 118, and steps 122 to 134).
