AI Customer ServiceMany researchers are working towards performance enhancement of solar thermal collectors. This article concentrates on solar air collectors and different types of modifications made in the recent past to improve its efficiency. This study is an attempt to summarize and present solar air heaters and various modifications for performance enhancement.
There are two types of applications employing solar air collectors the open circuit, and the recirculating applications. In open circuit, heated ambient air is used in industrial applications where because of contaminants recirculation of air is not possible. Examples are drying, paint spraying, and supplying fresh air to hospitals.
A simple solar air collector consists of an absorber material, sometimes having a selective surface, to capture radiation from the sun and transfers this thermal energy to air via conduction heat transfer.
Air is sometimes used as the heat transport medium in solar collectors, offering advantages over water. To reduce the power needed for air circulation, wider flow channels are used, such as spaces between the absorber plate and insulator with baffles creating a zig-zag flow path.
An energy efficient solar collector should absorb incident solar radiation, convert it to thermal energy and deliver the thermal energy to a heat transfer medium with minimum losses at each step. It is possible to use several different design principles and physical mechanisms in order to create a selective solar absorbing surface.
In particular, the enhanced heat transfer technologies by using a highly efficient heat transfer component (heat pipe, etc.) have been reported. Based on the analysis of the existing solar air collectors studies, this study provides a perspective for researchers to further and better study SAC technologies.
