TL;DR: In this paper, a solar/gas cooling plant at the Engineering School of Seville (Spain) was tested during the period 2008-2009, where the solar collector size and dirtiness, climatology, piping heat losses, operation control and coupling between solar collector and chiller were evaluated.

TL;DR: In this paper, a review of the previous work on solar drying systems which implemented the phase change material (PCM) as an energy storage medium is presented, and it is concluded that the solar dryer with a PCM reduces the heat losses and improves the efficiency of the system.
Abstract: Using phase change material (PCM) as an energy storage medium is one of the most efficient ways of storing thermal energy. The latent heat storage provides much higher storage density than sensible heat storage, with a smaller temperature difference between storing and releasing heat. In addition, phase change materials provide constant and moderate temperature which is needed for drying most agriculture crops sufficiently. This paper reviews the previous work on solar drying systems which implemented the phase change material as an energy storage medium. It is concluded that the solar dryer with a PCM reduces the heat losses and improves the efficiency of the system. Furthermore, this review paper summarizes the previous methods that have been used for improving the thermal conductivity of the used phase change material particularly paraffin wax since it is commonly used as a storage medium in solar drying systems. It is inferred that carbon fibers, expanded graphite, graphite foam and high thermal conductive particles may improve the thermal efficiency of solar energy devices employing paraffin waxes as thermal energy storage media.

TL;DR: In this paper, an indirect type forced convection solar dryer using Phase Change Material (PCM) was designed, constructed and experimentally investigated, which consists of a solar air panel for a direct heating of the drying agent, a solar energy accumulator (solar air collector with PCM cavity) and a drying chamber.
