Antarcticite: A Phase Change Material for Thermal Energy Storage-Experiments and Simulation
Antarcticite, CaCl2 center dot 6H(2)O, is an ideal phase change material (PCM) due to its high-energy storage density and good thermal conductivity. In this chapter, supercooling and subsequent solidification behavior of antarcticite are studied based on the cooling curve method and DSC measurement....

Summary: | Antarcticite, CaCl2 center dot 6H(2)O, is an ideal phase change material (PCM) due to its high-energy storage density and good thermal conductivity. In this chapter, supercooling and subsequent solidification behavior of antarcticite are studied based on the cooling curve method and DSC measurement. The results show that the minor SrCl2 center dot 6H(2)O as the nucleator and carboxymethyl cellulose as the thickening agent could significantly reduce supercooling and partly restrain the phase separation. Moreover, we incorporated antarcticite as PCM into building envelopes in four different cases, and the simulation of the heat transfer processes showed that the temperature fluctuation could be reduced to about 2 degrees C in the best case.
