In this paper the thermal adaptive effect and thermal characteristics of positional adjustment of a seated human body was simulated by changing the human model's position relative to the cooled spot airflow by means of coupled simulation of convection, radiation, moisture transport, and Fanger's neutral model. However, the human thermal models of Fanger, by focusing on the heat balance on the human body, consider the human body as an average, static heat source. It is often used to predict the average thermal sensation, but if facing a non-uniform thermal environment, the accuracy of its result becomes doubtful. Sakoi's model is proposed as a three-dimensional human thermal model to predict the distribution of human's thermal physiological state. This model's characteristics are that for instances the heat transfer is based on blood flow which is simulated through heat transfers between blood pool networks and body tissues, moreover the blood flow's style will change from contercurrent-flow to one-way flow depending on the perfusion rate of the skin tissue etc. Therefore, we use Sakoi's model instead of Fanger's model in the same simulation calculation in order to get more accurate results.
