Elaboration of mathematical analogues for the human thermal system implies that various simplified, steady-state and dynamic, heat transfer situations are experimentally mastered with full repeatability. In a stable thermal environment, the high thermal time constants of peripheral tissues and individual structural and functional differences impede the achievement of comparable and reproducible stationary and dynamic heat transfer situations in the organism at rest and during exercise. However, by active governing of the skin temperature, the establishment of steady states can be greatly accelerated and the development of desired dynamic states is under control. The aim of the study was to develop a set of equipment for regional controlling of skin temperatures and equipment for measuring the external heat exchange of the different parts of the body. The methods and equipment have been applied in testing a simple mathematical model which was worked out to describe the passive part of human heat transfer system. Author
