Researchers in China developed a large-scale PV-thermal heat pump system using a liquid overfeed method that reportedly improves both thermal and electrical efficiency. Field tests showed up to a 4.81% boost in power generation and significantly reduced pressure losses compared to conventional systems.A research team from China's Dalian University of Technology (DUT) has investigated the operational performance of a large-scale photovoltaic-thermal (PVT) heat pump system using a liquid overfeed method. Unlike conventional direct-expansion systems-where the expansion valve sends a mixture of liquid ...Den vollständigen Artikel lesen ...
