Solar energy is an abundance, inexpensive and clean source of energy. Using this energy source can be widely spread as the efficiency of solar systems improves. The main component of any solar thermal system is the solar collector which absorbs the incident solar radiation and converts it into heat. Solar thermal systems are categorised into two major types as air and liquid heaters. A solar air heater (SAH) is used for space heating and crop drying. A solar water heater (SWH) is used to supply hot water for domestic and industrial applications. However, air and liquid collectors are considered as a single purpose collector since the working fluid is air or liquid only. One way to enhance the performance of solar thermal systems is by combining both air and liquid heaters in one facility called dual-purpose solar collector (DPSC). This collector is basically a flat plate solar collector (FPSC) with two sections, one for air heating and the other for water heating. Therefore, it can produce hot air and hot water simultaneously. Using DPSC can attain high temperature, and high thermal performance with a reduction in cost and space. Despite many significant investigations on DPSC, no review paper has been seen. This article presents the different designs and applications of DPSC and the parameters affecting its performance. A comparison between single and dual-purpose solar collectors is also discussed. Moreover, the possibility of integrating DPSC in some automobile manufacturing processes is suggested in this article as well.
