On the
other hand, LHS, with solid–liquid phase change, has received
considerable attention in solar systems due to the follow
advantages:
(i) It involves PCMs that have high latent heat storage capacity.
(ii) The PCMs melt and solidify at a nearly constant temperature.
(iii) A small volume is required for a latent heat storage system,
thereby the heat losses from the system maintains in a
reasonable level during the charging and discharging of heat.
