In the present study, a new secondary refrigerant was investigated using urea-water mixture. And we developed the new fluid latent heat storage material. As the urea-water mixture is a binary solution, it can have a solid-liquid phase. But there are so few data available at present for describing the behavior of the urea-water mixture. In this study, the differential scanning calorimeter (DSC) was used to construct the phase diagram of the urea-water mixture and investigate the latent heat of ethanol water solution.
