SIMULATED PERFORMANCE OF SOLAR DOMESTIC HOT WATER TECHNOLOGIES IN NEW YORK STATE

In this paper, the performance of Solar Domestic Hot Water (SDHW) systems and baseline conventional DHW systems are simulated in thirteen regions of New York State using TRNSYS simulation software. The SDHW design factors considered in this assessment include collector type (flat plate, evacuated tube, unglazed building-integrated) and tank configuration (single tank, two tank, external heat exchanger, SDHW tank with instantaneous water heater). SDHW system performance is evaluated against conventional DHW system performance in terms of energy production and solar fraction. The results are rendered into color geographical maps of New York State, where the different colors represent different values of the solar fraction for the selected system.
