5.2. Moisture transport – Constant outdoor climate data
By use of the spread sheet model, for stationary calculations, the drying out capacities of two transport mechanisms,
airflow and diffusion, has been studied for a window as shown in figure 1. Calculated results, together with the input
values for the main parameters, are shown in table 1. The results show that moisture transport by airflow is a factor
15 to 245 larger than the moisture transport by diffusion.
5.3. Moisture transport - weather data for Bellenburg
The calculation program was revised and some calculations with weather data for Bellenburg have been performed.
For these calculations the vent openings at top and bottom of the outer window sash is randomly selected (see table
2). Fig. 4 and 5 show measured and estimated (calculated) temperatures and relative humidity for the window and
outdoor.
