To develop mathematical models of thermal systems, we use the concept of energy balance. The energy balance equation simply states that at any given location or node in the system, the amount of heat entering that node is equalto the heat flowing out of that node plus any heat that is stored (heat is stored in the form of a temperature increase in the heat capacity).
The mathematical model of the thermoregulatory system of the human body uses finite difference techniques, contains new basic anatomical and physiological information and is more detailed than previous models suggest and show that skin heat flux can be an important input to the thermoregulatory system. 215
