Abstract

There is a lack of studies that consider thermosyphon solar water heating systems under operation. This study presents procedures to model and validate a thermosyphon solar water heating system simulated using EnergyPlus software under different usage conditions. The system was validated by comparing it with measurements obtained in a social housing complex. Five clusters that represent the diversity in system usage were considered. The Root Mean Square Error (RMSE) between the simulated and measured values was adopted. The maximum and minimum RMSE obtained were 10.26% and 4.76%, respectively, which demonstrate the possibility of using EnergyPlus to simulate thermosyphon solar water heating systems.
