Thermal Comfort Study In Automobile Passenger Compartment Based On Human Thermoregulation Model

With the rapid development in automobile industry, thermal comfort in car passenger compartment is becoming much more significant than before. And many researchers and scholars start to join or have already joined the team to study it. However, complicated inner structure, air condition parameter setting, accurate setup boundary conditions for solar radiation, human thermoregulation model application, as well as the evaluation system for thermal comfort adds much difficulties on the research. In order to improve the development, this paper has made a try on human thermoregulation model. The main content and conclusion of this thesis show as follows:Based on a real car model, a simplified car passenger compartment is built and researched. By applying human thermoregulation model and setting up the proper boundary conditions, thermal fluid has been computed and thermal comfort evaluation is implemented.The control of iteration computation between human thermoregulation model and CFD, together with reasonable analysis are the key points in the research.During the process of results dealing, various kinds of tools are used such as theoretical analysis, sampling and statistical analysis and evaluation standard system, to deal with the large number of pictures and data including velocity, pressure, temperature, relative humidity and so on. All these could be taken as references to evaluate thermal comfort in the further.In this thesis, the innovative point is: the iteration computation between the thermal computation in car passenger compartment and the thermal regulation model. The interaction between the two is taken into consideration, not just passively take the whole human body as a thermal boundary condition.
