摘要: In order to utilize solar energy effectively and achieve a higher electrical efficiency by limiting the operating temperature of photovoltaic (PV) panel, novel photovoltaic/thermal solar-assisted heat pump (PV/T-SAHP) system was proposed constructed. The hybrid generates electricity thermal simultaneously. A distributed parameters model PV/T-SAHP developed applied analyze dynamic performance in terms PV action, photothermal action Rankine cycle processes. simulation results indicated that coefficient (COP) can be much better than conventional pump. Both PV-efficiency photothermic have been improved considerably. also showed this strongly influenced evaporator area, tube pitch tilt angle PV/T evaporator, which are key factors optimization design.
