Abstract

An educational solar water heater with phase change material (PCM) was designed, developed, and constructed for instructional and demonstrative purposes. This interactive solar water heating system experimental apparatus is capable of demonstrating thermal energy storage and heat transfer concepts and principles. The system consists of two simultaneously functioning heat absorbing units. The first is a flat plate solar collector and the other is a heat storage unit consisting of phase change material (paraffin wax). The heat storage unit utilizes small aluminium cylinders (heat exchangers) filled with paraffin wax as the heat storage medium. Water pump is used to circulate the water between the solar collector and the storage unit where the PCM is located. Results indicate that the PCM stored energy, as latent heat, that was absorbed by the solar collector and released to heat the water in the storage tank when half of the hot water was replaced with cold water. Moreover, tests indicated that latent heat storage is more effective than sensible.
