EVALUATING THERMAL ENVIRONMENTS BY USING A THERMAL MANiKiN WiTH CONTROLLED SKiN SURFACE TEMPERATURE

  • S. Tanabe
چکیده

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 data were collected. The manikin-based equivalent temperature (teq) is shown to be effective at accounting for the effects of local heat sources and asymmetrical environmental conditions.

Development 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...

Use of a Thermal Manikin to Evaluate Human Thermoregulatory Responses in Transient, Non-Uniform, Thermal Environments

People who wear protective uniforms that inhibit evaporation of sweat can experience reduced productivity and even health risks when their bodies cannot cool themselves. This paper describes a new sweating manikin and a numerical model of the human thermoregulatory system that evaluates the thermal response of an individual to transient, non-uniform thermal environments. The physiological model...

Evaluating the Effects of Ceramic Layer and Thermal Dam on Optimizing the Temperature Gradient of a Gasoline Engine Piston (TECHNICAL NOTE)

The purpose of this paper is to evaluate the effect of different methods for improving the temperature gradient of a specified gasoline engine piston. With a robust FE based software, 3D thermal analyses have been carried out for the piston model. Unlike previous studies, the effects of both fully and locally ceramic layers on the crown top surface were considered. It was found that a fully cer...

Evaluation of an electrically heated vest (EHV) using a thermal manikin in cold environments.

We studied the heating efficiency of an electrically heated vest (EHV), its relationship to the microclimate temperature distribution in a three-layer clothing ensemble, and the effect of an EHV on the clothing's total thermal insulation by both theoretical analysis and thermal manikin measurements. The heat losses at different ambient conditions and heating states were recorded and the heating...
