Equivalent temperature

Equivalent temperature refers to a uniform temperature of an imaginary enclosure with still air, in which a person would exchange the same dry heat, by radiation and convection, as in the actual environment. It is also defined as the constant temperature that leads to the same annual damage as the actual temperature distribution of the site under consideration. The concept of equivalent temperature allows eliminating from the equations the energy necessary for phase changes, resulting in a model that is feasible to use and programme.From: Human Thermal Comfort [2019], Effect of climate on asphalt pavement performance using two mechanistic-empirical methods [2022], High-precision machining in the shipbuilding industry.

Equivalent Temperature was defined as the uniform temperature of an imaginary enclosure with still air, in which a person would exchange the same dry heat, by radiation and convection, as in the actual environment. It therefore uses the standard environment approach to define equivalence, although the index value has yet to be directly related to thermal comfort. By definition, it does not include sweating and heat loss by evaporation, which are often causes of discomfort in vehicles. It is particularly relevant to the evaluation of asymmetric environments and measurement typically involves the use of thermal manikins although other methods are acceptable. The Equivalent Temperature index was extensively studied and developed by a multi-national European research project (EQUIV), which greatly influenced international standards ISO 14505 Parts 1–4 (Nilsson et al., 1999). The Society for Automotive Engineers in fact had adopted the Equivalent Temperature index from earlier research (SAE, 1993).
