Comparison Between TRNSYS Software Simulation and F-Chart Program on Solar Domestic Hot Water System

This study presents the accuracy test of a TRNSYS Solar Domestic Hot Water (SDHW) System simulation. The testing is based on comparing the results with the F-Chart software. The selected system to carry out the tests was the Active Solar Domestic Hot Water System in the F-Chart and the Houston TMY2 weather was used for the simulations. The comparison of the accuracy tests showed that solar fraction from the TRNSYS simulations are in a 0% - 19.6% range with respect to one that are performed by the F-Chart program
