heal.abstract | Μελέτη της επίδρασης διαφόρων κλιματολογικών αλλά και κατασκευαστικών παραγόντων στην ηλεκτρική, θερμική και εξεργειακή απόδοση ενός θερμοφωτοβολταϊκού με χρήση νερού και νανοϋλικού σαν εργαζόμενο μέσο καθώς και δοκιμή διαφόρων όγκων δεξαμενής αποθήκευσης του νανορευστού με σκοπό την βέλτιστη συνολική απόδοση. | el |
heal.abstract | The objective of this study is to estimate the thermal and electrical enhancement of a hybrid PV operating with nanofluid. The examined nanofluid is Cu/water and it is compared with water as working fluid for various operating conditions. An integrated solar thermal system with a hybrid PV and a storage tank is examined to calculate the thermal and electrical power produced. The influence of various factors such as the intensity of electrical radiation, ambient temperature, supply and temperature of the working fluid, wind speed and the emission factor of the slab in the thermal, electrical and eρergetic efficiency of the system are examined. Different storage tank volumes are investigated because of the storage capacity influence on the thermal and the exergetic performance of the system. According to the final results, the storage tank of 150 L is found to be the most suitable solution for the hybrid PV of 2 m2 collecting area, using exergetic criteria. The increase in thermal performance observed with nanofluid is about 6. 59%, while the electrical is 1.02%. In addition, in the case that a storage tank is used, it is noted that the increase is higher in cases with larger storage tanks. The study is conducted with a developed thermal model EES (Engineering Equation Solver), which is validated with experimental literature results. Climate data has been obtained from the bibliography for Athens, Greece. | en |
