The melting process of the PCMs was analyzed using

Additionally, it resulted in a reduction in cooling costs of up to 20 %. Furthermore, Riahi et al. [16] examined the effect of adding a PCM storage tank to an air conditioning system experimentally.

The thermal behaviour of a PCM storage tank was compared with the same tank using water as sensible heat storage medium. The results have demonstrated that the PCM storage tank gives some advantages over the water one.
When using the PCM tank, the charging process aims to solidify the PCM of the cold PCM tank, so that thermal energy is stored as latent heat. During the charging mode the heat pump runs supplying hot HTF from the condenser at around 50 °C and cold HTF from the evaporator at 2.5 °C as minimum temperature, which solidifies the PCM.
PCMs can also be used to provide thermal barriers or insulation, particularly useful for industry sectors such as temperature-controlled transport. Interestingly, the simplest, cheapest and most effective Phase Change Material is water/ice.
From the results it is clearly observed that the PCM tank needed a longer time to charge compared to the water tank. In particular, the PCM tank took 234 min for test 1 and 225 min for test 2 to be charged while the water tank needed 48 and 44 min for test 1 and test 2, respectively.
