Tetra-n-butylammonium bromide (TBAB) hydrate and tetra-n-butylammonium chloride (TBAC) hydrate are used as a thermal energy storage media for air-conditioning system. However, these hydrates often tend to be in supercooling state when the hydrates form from the aqueous solutions. This is a prime problem to use them as thermal storage media because the COP is decreased by supercooling. In a previous study, it was revealed that applying voltage to the solution can promote the nucleation of TBAB hydrate. The key factor of the nucleation-promoting effect was a material generated from electrodes and it was revealed that the material was composed of some metals by X-ray diffraction analysis. In this study, the nucleation-promoting effects of these metallic particles on tetra-n-butylammonium salt hydrate were investigated experimentally. It was found that significant nucleation-promoting effect on TBAB hydrate was confirmed when 2 kinds of metallic particles were ground by a mortar and added to the solutions.
