摘要: Abstract Phase Change Materials (PCMs) may be incorporated in solar thermal energy systems to act as latent heat storage media offering a high capacity compared sensible storage. In this work, collector that consists of six 80-mm diameter copper pipes connected series is integrated with back container paraffin wax PCM media. Outdoor experiments are carried out demonstrate the potential system for water heating. The performance evaluated by calculating various factors collector. plate temperature found increase up distance 2.5 m from entrance, after which an almost steady noticed. Such trend was contrast increasing previously noticed similar without layer. During off-sunshine hours, liquid transferred absorber, part conducted useful circulating water. Therefore, continued get heated sunset, acted source.
