SET

Providing cooling effect with low energy consumption makes the exploration of air flow utilization significative. In ASHRAE Standard 55-2010, the cooling effects of elevated air movement are evaluated using the SET index as computed by the Gagge 2-Node model of whole-body heat balance. Air movement in reality has many forms, which might create heat flows and thermal sensations that cannot be accurately predicted by a simple whole-body model, and the affected body surface might be variably nude (e.g. face) or clothed.
