A New General Formulation for the PMV Thermal Comfort Index

The PMV index forms the basis of international thermal comfort standards. was developed based on empirical relationships between metabolic rate activity and body mean skin temperature evaporative heat loss under conditions. However, many recent studies have questioned accuracy reliability predictions, particularly for discomfort range. This paper develops a general formulation that does not involve loss. new metabolic-based predicted vote (MPMV) is expressed as difference required to achieve state imposed environment found vary linearly with maintain core temperatures at resting thermo-neutral state. model constants are determined using public experimental data sensation votes young older people. accounts cooling hot exposures; it also addresses overlooked non-shivering thermogenesis in balance covers requirements people wakeful sleep states.
