PURPOSE:To improve the feeling of cooling, by deciding a cooling capacity through the detection of an air temperature after passing through an evaporator when a target air quantity time on the basis of car room inside and outside temperatures and the quantity of sunlight, has been made to change upward/ downward, and correcting a target air quantity. CONSTITUTION:A controller 21 calculates a target air quantity on the basis of car room inside and outside temperatures, the quantity of sun light, a set temperature by means of a PTC 22, or the like, and drives a ventilating means 4 by means of a motor 3. At the time of this target air quantity and when the target air quantity has been made to change upward/downward, each air temperature after passing through an evaporator 5 is detected by means of a sensor 6. Hereupon, when an air quantity has been changed in the direction of increase, there is the tendency of an air temperature rising up rapidly, if the cooling capacity of the evaporator 5 has reached its limit, so the cooling capacity is decided on this tendency, and a correction is made so that the value of the target air quantity may become within that of the cooling capacity of the evaporator 5. Thus, the improvement of a cooling feeling can be realized. |
