Analysis of Simulation Results
Temperature characteristic
Figs. 2 and 3 show temperature characteristics from the simulation results for the DSF model without PV.
As shown in Fig. 2, the maximum solar radiation in summer is 391.85W/m2 with outdoor temperature of 28.4°C. In the DSF model, the external wall had a peak temperature of 41.63°C, followed by
the cavity at 34.34°C, approximately 6°C higher than the outdoor temperature.
For the winter, as shown in Fig. 3, the highest external temperature is 5.8°C. The solar radiation
rose to 770.66W/m2.
In winter, Glass.inside had the highest temperature of 17.4°C, followed by External Wall, Cavity, and
Glass.outside. The maximum temperature of the cavity was 13.71°C, or 8°C higher than the external
temperature.
The analysis revealed more concerns for increased load caused by heat insulation during the
summer, when the cavity temperature rises significantly by solar radiation. In winter, however,
the cavity temperature is higher than the outdoor temperature, which is considered to be more
beneficial in terms of heating load.
