PURPOSE:To make a refreshing feeling ever so better and prevent a driver from going to drowsiness as well as to aim at a distinct improvement in comfortableness, by detecting the degree of air pollution inside a car room, while constituting an air conditioner so as to change a blast air quantity according to the degree of air pollution. CONSTITUTION:Carbon dioxide content inside a car room is detected by a carbon dioxide sensor 7. On the basis of an increase in the level of this detected signal, amplitude of an oscillator 8 grows large. With this amplitude increment, a fan speed control 9 increases a revolution mean value and the amplitude of a periodic blowoff of the fan 10 in proportion to an increase in solar radiation. With suchlike constitution, an air flow feeling can be inceased with the carbon dioxide increment and a distinct improvement in a refreshing feeling, allowing people aboard to enjoy their driving comfortableness. |
