PCS-Systems in cooling and cold supply networks.

Auteurs : POLLERBERG C., NOERES P., DÖTSCH C.

Résumé

Fraunhofer UMSICHT has investigated PCS systems in view of their possible application in cold supply systems. Paraffin/water emulsion and encapsulated paraffin/water suspension are discussed as heat transfer fluid as an alternative to cold water. Tetradecane was chosen as paraffin for these fluids because of its melting point of 5°C. Ice-slurries can be used for the temperature range under 0°C. This paper describes the thermal and rheological characteristics of tetradecane/water emulsion, encapsulated tetradecane/water suspension and Ice-slurries. Furthermore, environmental aspects and the technological feasibility are discussed for the future use of PCSs in cold supply systems. Finally, an economical comparison of the PCS is given to show convenient fields of application.
