Low temperature paraffin phase change emulsions

A paraffin phase change emulsion is a multifunctional fluid consisting of water as the continuous phase and a paraffin as the dispersed phase. It can store or transfer large amounts of thermal energy by using the latent heat capacity of the paraffin during the solide-liquid transition as well as the sensible heat capacity of water and that of the paraffin. This paper presents three paraffin emulsions with different phase transition temperatures: CryoSolplus6, CryoSolplus10 and CryoSolplus20. CryoSolplus6 is foreseen for airconditioning applications with a freezing peak point of 6 °C, CryoSolplus10 for cooling of buildings with a freezing peak point of 10 °C and CryoSolplus20 for increasing the thermal storage mass of building components with a freezing peak point of 20 °C.
