Low temperature paraffin phase change emulsions

Abstract

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 solid–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 air-conditioning 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.
