Abstract

Water purification is one of the major natural requirements for humanity. A Solar still is a
one of the low cost methods that produces pure and drinkable water from saline water by
utilizing the solar radiation. For improving the efficiency of solar still numerous methods
are being used in the recent years. Phase Change Material (PCM) is utilized in solar still
which is discovered to be the most ideal alternative to expand the proficiency of solar still
at daytime as well as during the evening. This kind of material has a higher advantage and
attention, so that in this study, we are justifying the properties of PCM thermal energy
during on distillation process and also we mentioned the reason behind why researchers
chose paraffin as a PCM for Thermal Energy System. And also we are including the
progress on improving the thermal conductivity property of PCM materials using
nanoparticles. Nano materials played a very important role on PCM and which is
enhancing the thermal conductivity behavior on thermal energy storage systems. In
addition, the tiny structure will cause nanoparticles to have an enormous surface region
that associates with their physical and chemical properties that respond to the thermal
properties of PCM. Here the thermal conductivity of PCM can be improved by including
exceptionally thermal conductive nanoparticles, for example, carbon nanotubes, graphene
and metal oxide nanoparticles are used in PCM.
