PURPOSE: To perform air-conditioning control matching body sensations by providing a fuzzy inference means for drawing a fuzzy inference from control information for the control of output equipment in response to the equivalent temperature and thermal environmental factor data.

CONSTITUTION: Output equipment for air-conditioning control is controlled on the basis of one or plural thermal environmental factor data. In this case, air conditioner is provided with an output means 52 for outputting blast speed data on the blast speed from a blowoff grille, and a computing means 53 for computing equivalent temperature on the basis of the blast speed data. In response to the equivalent temperature and thermal environmental factor data, a fuzzy inference means 55 draws a fuzzy inference from control information for the control of the output equipment. Desirable temperature control matching body sensations is thereby performed.
