Sugar alcohols are potential phase change materials candidates as they present high phase change enthalpy values, are non-toxic
and low cost products. Three promising sugar-alcohols were selected: D-mannitol, myo-inositol and dulcitol under high melting
enthalpy and temperature criterion. Thermal cycling tests were performed to study its cycling stability which can be determining
when selecting the suitable phase change material. D-mannitol and dulcitol present poor thermal stability. Myo-inositol shows
almost no decrease in thermal properties after 50 cycles for the heating process, however in the solidification part a decrease of
20 % of enthalpy and 11 % of temperature values is observed.
The research leading to these results has received funding from the European Community's Seventh Framework
Programme (FP7/2007-2013) under grant agreement 296006. |
