Measurement Uncertainty Budget of the PMV Thermal Comfort Equation

Abstract

Fanger's predicted mean vote (PMV) equation is the result of the combined quantitative effects of the air temperature, mean radiant temperature, air velocity, humidity activity level and clothing thermal resistance. PMV is a mathematical model of thermal comfort which was developed by Fanger. The uncertainty budget of the PMV equation was developed according to GUM in this study. An example is given for the uncertainty model of PMV in the exemplification section of the study. Sensitivity coefficients were derived from the PMV equation. Uncertainty budgets can be seen in the tables. A mathematical model of the sensitivity coefficients of T-a, h(c), T-mrt, T-cl, and P-a is given in this study. And the uncertainty budgets for h(c), T-cl, and P-a are given in this study.
