A simple method to incorporate thermal bridge effectsinto dynamic heat load calculation programs

The aim of this study is to develop a simple method to predict heat flows and minimum surface temperatures in dynamic heat load calculation programs. A composition of two linear flow components is assumed instead of an element including a thermal bridge. A fractional area of the thermal bridge part is determined by the maximum and the average thermal transmittances. We also discuss a method to constitute a one-dimensional imaginary component of the thermal bridge.
