Abstract
According to a method and apparatus for calculating predicted mean thermal sensitivity which is used to control an air conditioning or heating unit, an operative temperature T.sub.0 is calculated on the basis of a radiant temperature Tr, an air temperature Ta, an air velocity Vair, coefficients b.sub.1 and b.sub.2, and a coefficient n according to the following equation: ##EQU1## Predicted mean thermal sensitivity PMV* is calculated on the basis of the operative temperature T0, the air temperature Ta, a relative humidity RH, a saturated water vapor pressure Pa*, a clothing thermal resistance Icl, a variable h.sub.0 (h.sub.0 =b.sub.1 +b.sub.2 .multidot.Vair.sup.n), and coefficients a.sub.1 to a6 according to the following equation: ##EQU2##
