Thermal manikin measurements--exact or not?
According to the European prestandard ENV 342:1998, the thermal insulation of cold-protective clothing is measured with a thermal manikin. Systematic studies on the reproducibility of the values, measured with different types of clothing on the commonly used standing and walking manikins, have not been reported in the literature. Over 300 measurements were done in 8 different European laborator...
متن کاملVirtual Thermal Manikin – Mathematical Modelling of Human Thermoregulation
Early works on so called segment (compartment) models were based on extremely simplified geometry and covered mainly only passive heat transfer [3,4]. Later developed models were devoted on development of active thermoregulation part, focusing on precise description of changes in: non-shivering thermogenesis (metabolic heat production), perfusion of selected tissues and sweating. The number of ...
متن کاملDevelopment of a two-layer movable sweating thermal manikin.
A thermal manikin is a useful tool to evaluate thermal environments such as clothing, houses and others. A manikin needs to have the following properties: shape and size, heat production, skin temperature, sweat rate, physiological responses and others. So far, no manikin satisfying all these criteria has been available. In the present study, a two-layer movable sweating thermal manikin was new...
متن کاملHow to measure thermal effects of personal cooling systems: human, thermal manikin and human simulator study.
Thermal effects, such as cooling power and thermophysiological responses initiated upon application of a personal cooling system, can be assessed with (i) humans, (ii) a thermal manikin and (iii) a thermophysiological human simulator. In order to compare these methods, a cooling shirt (mild cooling) and an ice vest (strong cooling) were measured using human participants and a thermal manikin. U...
متن کاملEVALUATING THERMAL ENVIRONMENTS BY USING A THERMAL MANiKiN WiTH CONTROLLED SKiN SURFACE TEMPERATURE
This paper describes a method for measuring nonuniform thermal environments using a new thermal manikin with controlled skin surface temperature. The manikin its control logic are described, and an equivalent temperature based on the therntal manikin (teq) is proposed and discussed. A method to calculate the PMV index from manikin heat loss is also given. To calibrate these methods, fundamental...
