PURPOSE:To improve the comfortability of airconditioning at front and rear seats by providing a means for detecting a thermal environment in a cabin and directing an airconditioned wind to rear seats when the steady state of the thermal environment at the front seats has been detected. CONSTITUTION:Output from a front seat room temperature sensor 25 and a rear seat room temperature sensor 29 is inputted to a control means 28. This control means 28 makes judgement as to whether a thermal environment at front seats is steady or not, on the basis of output from the front seat room temperature sensor 25. If the environment is not steady, the valve of an air quantity and direction setting devices 31 for side vents 16 and 19 and center vents 17 and 18 is opened, thereby concentrating the diffusion of airconditioned wind to the front seats. And when the thermal environment at the front seats has become steady and room temperature at the rear seats has not reached a predetermined level, the air diffusion direction of the center vents 17 and 18 is changed toward the rear seats and an air distribution ratio of the center vents 17 and 18 to the side vents 16 and 19 is taken to give a larger value for the center vents 17 and 18. According to the aforesaid constitution, comfortability at both front and rear seats can be improved. |
