Abstract

This paper presents self-sufficient control design and performance evaluation for a photovoltaic/thermal-assisted heat pump water heating (PVTA-HPWH) system. The developed PVTA/HPWH model was built by considering the reciprocal energy exchange of PVT evaporator and HPWH system. In addition, the power consumption of HPWH is self-sufficiently provided by PV electricity using a model-based control methodology. System performance is evaluated through a real field test. The results have demonstrated the power autarky of the proposed PVTA/HPWH system with better performance. In addition, good agreements between model simulation and experiment measurement demonstrate the proposed model with sufficient confidence.
