Abstract

Cooling processes require heat transfer fluids with high specific heat capacity. For cooling processes below 0 °C, water has to be diluted with organic liquids to prevent freezing, with the undesired effect of reduced specific heat capacity. Phase change dispersions, PCDs, consist of a phase change material, PCM, being dispersed in a continuous phase. This allows for using the PCD as heat transfer fluid with a very high apparent specific heat capacity within a specified, limited temperature range. So far, the PCMs being reported in the literature are paraffins, fatty acids, or esters and are used for isothermal cooling applications between +4 and +50 °C. They are manufactured by high shear equipment like rotor-stator systems. A recently published method to produce emulsions by the direct condensation of the dispersed phase into the emulsifier-containing continuous phase is applied on this PCD.
