Model validation of a residential solar thermal combisystem

Anthony Rey, Radu Zmeureanu

Abstract: This paper presents the validation of a TRNSYS model of a residential solar thermal combisystem installed in the United States. This solar combisystem, installed in an occupied house, is composed of two distinct arrays of flat-plate collectors of 15.8 m² connected to a thermal storage tank of 617 liters, and provides for domestic hot water and space heating. The available measurements used for the model validation are from January to December 2014. The paper presents the system and uncertainty analysis of measurements. The main characteristics of the TRNSYS model are presented, followed by the comparison of the model predictions with the measurements of some selected variables of interest. For instance, the coefficient of variation of rootmean-squared error (CVRMSE) for the measured temperatures ranged from 8.6% to 25.1%.
