PURPOSE:To make the clouding produced on a windowpane inside eliminable with certainty, by controlling an air conditioner on the basis of not only a main cause producing the clouding inside a car room but also that producing it outside the car room. CONSTITUTION:This air conditioner is provided with a clouding discriminator circuit 20, which finds size of the outside signal of a dew drop sensor 7 to be installed in a windowpane inside and discriminates for whether clouding occurs or not, and in time of clouding occurring, selects an H signal to be fed to a terminal 9 at a selector circuit 8, then feeds this signal to a clouding removal command circuit 11. Also, it is provided with an operation circuit 18 into which each output signal out of an outside temperature sensor 4 and a temperature sensor 19 detecting temperature at the outer surface side of a windowpane is inputted. This operation circuit 18 is below the specified valve of the outside temperature (for example, a temperature of 19 deg.C), and set in motion by the H signal of an AND circuit 16 in time of operation in the said command circuit 11. And, when a temperature difference obtainable from outputs of both sensors 4 and 19 is above the fixed valve (about 2-3 deg.C), it controls the said command circuit 11 and holds the temperature difference into a clouding removal mode. |
