Numerical and Experimental Comparison of the Performance of Standard and PV-SDHW System
Abstract
In this paper, various configurations of PV assisted Solar Domestic Hot Water (SDHW) systems using different pump are evaluated numerically and experimentally. A detailed model of direct current (D.C) pump on considering a multi-physics modeling (thermal, hydraulic, electric and mechanic) has been developed in TRNSYS environment. Different electronic devices (Linear Current Booster, Maximum Power Point Tracker, special start-up control device) are also integrated in order to compare these different solutions of ‘solar pump’ proposed by manufacturers. The models of pump and electronic devices are validated thanks to the experimental set-up installed in the French National Institute for Solar Energy. The numerical data show a good agreement with the experimental results.
