The amount of ice formed, as a consequence of the adsorption of methanol by the activated carbon, will be used to
cool the refrigeration compartment during night. The quantity of water chosen for cold storage is 2 kg, which takes
more than 4 hours to melt totally. The following figures show the temperature evolution of the ice during its melting
phase, assuming that the initial temperature of the ice is -4°C. Figure 4 illustrates the fusion of the total mass of
PCM in direct contact with the evaporator. Figure 5 presents the fusion of a portion of PCM only.
