PURPOSE:To obtain accurate detection of the state of air pollution regardless of the working condition of an air conditioner by installing an air pollution sensing element within the fan-diameter of a wind introducing fan of a radiator. CONSTITUTION:A sensing element 7 is situated in the wind-duct of a wind introducing equipment 3, leads from a vent hole 6 and passes a radiator 2, and moreover it is supported by a bracket 8 in such a manner that it is situated within the diameter of the circle drawn by rotating blades of a fan in the equipment 3. The sensing element 7 incorporates a transmitted-light-type or scattered- light-type optical particle sensor. |
