PROBLEM TO BE SOLVED: To enable noise caused by blower operation to be prevented or reduced and power consumption to be reduced when a blower for a front seat and a blower for a rear seat are continuously operated even while an engine is automatically stopped, as well as to secure time allowing the engine to be stopped as long as possible while passenger comfort is secured.SOLUTION: Heat capacity of a heat exchanger 5R (10R) for a rear seat is set less than capacity of a heat exchanger 5 (10) for a front seat. A blower 4 for the front seat and a blower 4R for the rear seat are continuously operated while an engine is automatically stopped, and there is initially applied a first control state (from t1 to t2 in Fig. 11, and from t11 to t12 in Fig. 12) in which air flow of the blower 4 for the front seat is less than air flow of the blower 4R for a rear seat. After the first control state continues to cause temperature of the heat exchanger 5R (10R) for the rear seat to exceed a predetermined threshold temperature, there is applied a second control state (from t2 to t3 in Fig. 11, and from t12 to t13 in Fig. 12) in which the air flow of the blower 4R for the rear seat is reduced as well as the air flow of the blower 4 for the front seat is increased.SELECTED DRAWING: Figure 11 |
