In recent years, extensive research of heat storage technology has been conducted for environment improvement. Among them, a research of a phase change material (PCM) has attracted attention as a new energy storage media. The reason for PCM such as the phase change nano-emulsions is that it is possible to disperse by absorbing the latent heat within the range of the phase change temperature. However, the nano-emulsion causes the supercooling when the phase changes. In this report, the supercooling control of the nano-emulsion was examined. Nano-emulsion was consisted of tetradecane, surfactant, and water. A polymer or a nano-particle was used as a nuclear agent. Regarding the fundamental phase change characteristics of the nano-emulsion, it was found that its phase change characteristics were strongly affected by polymer. However, it was not affected by nano-particle.
