TBAB (Tetrabutylammonium bromide) hydrate has advantages as thermal storage material. For example, the phase change temperature, which is from 0 to 12℃, is suitable for use in air conditioning, and the latent heat is relatively large. Thus, thermophysical properties of TBAB hyadrate such as latent heat is useful. However, it is difficult to measure the latent heat with high accuracy by using DSC, because the accuracy of measurement of mass of sample is limited. In this study, large TBAB hydrate crystal is formed and the latent heat of TBAB hydrate is measured using the crysta.
