Comprehensive Investigation of Solar Water Heater System Performance, Stratification, Charging, and Discharging Efficiency Using TRNSYS Software.

A study by dynamic simulation using the TRNSYS software was carried out to visualize the performance of a solar water heater with forced circulation for one year. Thermal needs in domestic hot water for an average family of six people living in the city of Oran in Algeria are covered by solar energy by up to 63%. Parameters such as the angle of inclination, the surface of the solar panel, the storage volume, the heat exchanger's surface, and the flow rate of the solar loop have been optimized. An analysis of the temperature stratification inside the balloon was presented, along with the calculation of charging and discharging efficiency. The influence of the position of the exchanger inside the tank has been shown on the temperature stratification and the charging and discharging efficiency [ABSTRACT FROM AUTHOR]
