Abstract
Thermal comfort and temperature sensation are important aspects for establishing a comfortable atmosphere and play a fundamental role in order to influence human's efficiency, respectively. It is often useful to know the limits of thermal acceptance and take measures to minimize disturbing influences.
Accurate comfort analysis has to consider human's thermal physiological reactions. The following theoretical concept aims to provide the basis to connect a manikin with a mathematical thermal physiological model. Such a model was introduced by Fiala Dusan [Fiala 1998] and is used to predict local skin temperature distribution. The combination of this model with an additional comfort analysis (Zhang 2003) enables the consideration of inhomogeneous environmental conditions.
The main subjects the present work aims to investigate are:
- Managing the complexity of the interface between manikin and thermal physiological model and developing a program in order to control the measurement progress.
- Mere mathematical implementation of evaporation.
- Validation of the theoretical concept on the basis of appropriate virtual
A measuring system with implemented thermal physiological model requires active measurement facilities. The function of such equipment is the imitation of real skin temperatures depending on environmental conditions. Peltier elements were found out to be appropriate for a practical realization of the theoretical findings.
