How to power buildings with solar-driven reversible heat pumps, organic Rankine cycle - pv magazine Global

Researchers in China proposed a solar-driven integrated system that combines reversible heat pump and organic Rankine cycle (ORC) technologies, enabling flexible switching between heating, cooling, and electricity generation for buildings. Simulation results show strong performance dependence on solar irradiance and temperature, with COP rising up to 4.1 and optimal operation achieved at 600–850 W/m² irradiance.
