A solar air collector isa system that transfers solar energy from the Sun to the fluid flowing through it. A solar air collector consists of an absorber, which is usually made up of material of high thermal conductivity such as Aluminum, as shown in Fig. 1. The absorber plate is coloured black to enable it to absorb maximum radiation.
A solar air collector (SAC) is a main device of a solar-thermal air system, which can absorb solar radiation and transfer the absorbed thermal energy to the air. This paper presents a systematic review of three basic types of SAC, namely, the flat-plate SAC (FPSAC), the evacuated tube SAC (EVTSAC), and the concentrated SAC.
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. The main conclusions can be drawn as:
Many 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.
Solar thermal collectors are used to collect solar thermal energy, and then it is transferred to the fluid. The fluid may be air, water, oil, etc. depending on the application. Many researchers are working towards performance enhancement of solar thermal collectors.
The yield of solar air collectors based on geographical and solar radiation conditions can be used as a further research parameter and application boundary conditions of SACs. At the same time, combing with local energy policies, elaborating its economic details or energy savings and providing emission reduction information are suggested.
