ABSTRACT:
According to a method and apparatus for calculating thermal sensitivity, a set temperature .theta..sub.(th) is calculated on the basis of an air temperature Ta and a clothing thermal resistance Icl. Thermal energy H.theta..sub.(th) is supplied to a heater capable of adjusting a sensor temperature Tcr so as to set the sensor temperature Tcr to be equal to the set temperature .theta..sub.(th). The thermal sensitivity is calculated on the basis of the air temperature Ta, the clothing thermal resistance Icl, the set temperature .theta..sub.(th), and the thermal energy H.theta..sub.(th).
