5 Physics Conduction 5

6 Energy transport through a material Depending on: material temperature difference density heat capacity conductivity Conduction Convection 6

7 Thermal driven air movement Depending on: air temperature and humidity surface temperature air velocity Convection Stratification 7

8 Stabile layering of air with different conditions Depending on: air density air temperature warm air is lighter than cold air humidity humid air is lighter than dry air air velocity Stratification Evaporation 8

9 Phase change of a material form liquid to vapor under energy input Depending on: humidity difference air temperature water temperature movement of water surface air velocity dew point of room air if below dew point -- condensation Evaporation Transmission/Reflection 9

10 Radiation transport through a material Depending on: material geometry wave length reflection coefficient extinction coefficient refraction index form, thickness UV, visible, IR Transmission/Reflection Heat-Radiation 10

11 Heat radiation happens between two bodies of different temperature 50% of heat transport is radiation Depending on: material temperature difference emission coefficient Heat-Radiation Concept and project examples 11
