G0600602 Phase Change Characteristics of Nanosuspension as Latent Heat Storage Material

Abstract

The purpose of this research is phase change characteristic evaluation of the nanosuspension type heat storage as latent heat material. The target heat storage zone of this study is 50-100℃ as for using of hot spring heat or factory exhaust heat. Tetracosane (50.6℃ of melting point) is used for dispersion material as a latent heat storage material of a nanosuspension. Tetracosane in the nanosuspension is dispersed by about 200 nanometers of average particle diameter in continuous water phase. A latent heat storage material is dispersed by using an ultrasonic homogenizer. This paper deals with the phase change characteristics that estimated by using differential scanning calorimeter. The heating rate and the composition of tetracosane are chosen as experimental parameter.
