Summary
In order to cope with the dew condensation, heat-flow analysis in the corner of three vertical wall has been taken
through three-dimensional element that relies on Finite Element Method (FEM). Performing heat insulating
design for preventing the dew condensation, the adiabatic quality in complete heat insulating was inspected based
on the characteristic of temperature boundary layer equivalent to convective heat transfer at the comer of wall.
The required thickness of heat insulating material was known under analyzing the relation among heat insulating
material thickness, the peak temperature in internal angle, the indoor air temperature and relative humidity and
the outdoor air temperature. The regression between indoor air temperature and heat insulating material
thickness was also considered. Moreover, the temperature distribution on the wall for arising the dew condensa-
tion would be analyzed through FEM considering the heat capacity of wall.
