| Abstract: | Thermal
energy storage plays an important role in the storage of available energy and
hence, improves its utilization during odd hours especially, in the presence of
an intermittent heat source. Phase change materials (PCMs) also play very
important role in thermal energy storage due to their qualities to store more
heat in small volume. But there are
some disadvantages in most of the inorganic PCMs, such as fluctuation in their
normal freezing point, known as supercooling behaviour. There are certain additives
that play an important role in minimizing and/or removing the supercooling
behaviour of different PCMs. In the present study, the supercooling behaviour
of a typical PCM and the effect of pH
value have been studied. The results obtained through experimental study have
been compared with those obtained through differential scanning calorimeter
(DSC) and found to be in good agreement with each other |
