To estimate the temperature of each zone with a fewer number of temperature sensor than the number of zones even if the number of divided zones of the room interior is increased.
When the inside of the cabin 2 is divided into total six zones of two of right and left, and three of front and rear, the temperature sensors 51 to 54 detecting the representative temperature of respective zones are disposed in four detection zones of the right front, right middle, right rear, and left middle. The temperature of the left front zone to be an estimation zone where the temperature sensor is not disposed can be estimated and calculated by adding the temperature difference Δ=TL2-TR2 detected in a pair of detection zones and the detection temperature TR1 of the right front to be the detection zones opposing to the left front and width direction. The left rear to be the other estimation zone can be estimated by the same way. Therefore, respective representative temperature can be determined only by providing a fewer number (4) of the temperature sensors than the number (6) of zones.
