Titel
Paraffin in water emulsion as heat transfer and storage medium
Abstract
A Phase Change Slurry (PCS) is a multifunctional fluid consisting of a Phase Change Material (PCM) and a carrier fluid. PCSs can store or transfer amounts of thermal energy by using both the sensible heat capacity of the carrier fluid and PCM as well as the latent heat capacity of the PCM. Fraunhofer UMSICHT has investigated three types of paraffin in water emulsions as PCS with different phase transition temperatures: CryoSolplus 6, CryoSolplus 10 and CryoSolplus 20. CryoSolplus 6 is foreseen for air-conditioning applications with a freezing peak point at 6 °C, CryoSolplus 10 for cooling of buildings with a freezing peak point at 10 °C and CryoSolplus 20 for increasing the thermal mass of building components with a freezing peak point of 20 °C. The different fields of applications have different requirements on the properties of the emulsions. How to meet these requirements is discussed in the following paper.
