Novel Models on Packed Bed Solar Air Collectors

This paper presents three different models for solar air collectors (SACs). Novel theoretical modeling of the overall performance of the thermohydraulic for solar air collectors having their duct full of blackened spherical particles (cupper spheres) has been introduced. The impact of the airflow course on the collector's powerful performance is investigated. In this investigation, fashions were proposed for airflow. In the first method (Model I), the air flows were parallel to the glass cover, whereas, within the second method (Model II), the air flows in a direction this is perpendicular to the glass cover. An evaluation has been made among the thermal performances of the sun air collector corresponding to each of the two airflow direction models for the equal duct depth and equal operating situations. It can be determined that there may be a considerable effect of airflow direction on overall thermal performance. The steady-state warmness balance equations for the packed bed collector are shown. A numerical answer turned into obtained for a wide variety of impartial parameters. The effects of various parameters on thermohydraulic overall performance are mentioned. The hole air temperature, thermal efficiency, and effective efficiency might be received. Its miles discovered the mass waft rates affect the overall collector performance extensively. Similarly, an evaluation between the performances of a packed bed collector (Model I) and its duct full of the blackened cord mesh display matrix are supplied. Its miles discovered that the round bed packed sun air collector (Model I) offers a more effective performance than the wire mesh packed air creditors.
