Dynamic coupled thermal-and-electrical modelling of sheet-and-tube hybrid photovoltaic/thermal (PVT) collectors
In this paper we present a dynamic model of a hybrid photovoltaic/thermal (PVT) collector with a sheetand-tube thermal absorber. The model is used in order to evaluate the annual generation of electrical energy along with the provision of domestic hot-water (DHW) from the thermal energy output, by using real climate-data at high temporal resolution. The model considers the effect of a non-unifo...

The model is used in order to evaluate the annual generation of electrical energy along with the 14 provision of domestic hot-water (DHW) from the thermal energy output, by using real climate-data at high 15 temporal resolution. The model considers the effect o...
متن کاملPerformance analysis of photovoltaic thermal (PVT) water collectors
The electrical and thermal performances of photovoltaic thermal (PVT) water collectors were determined under 500–800 W/m solar radiation levels. At each solar radiation level, mass flow rates ranging from 0.011 kg/s to 0.041 kg/s were introduced. The PVT collectors were tested with respect to PV efficiency, thermal efficiency, and a combination of both (PVT efficiency). The results show that th...
متن کاملDemonstration of the Performance of an Air-Type Photovoltaic Thermal (PVT) System Coupled with a Heat-Recovery Ventilator
A heat-recovery ventilator (HRV) effectively conducts ventilation by recovering waste heat from indoors to outdoors during heating periods. However, dew condensation associated with the HRV system may arise due to the difference between the indoor temperature and the very low outdoor temperature in winter, and this can decrease the heat exchange efficiency. These problems can be solved by the p...
