performance. Abstract. This paper presents the preparation for phase change materials(PCM) with different phase change temperature for use in refrigerated transport equipment. The optimal preparation condition of HSD-1 as the PCM was confirmed. The thermo-physical properties of the modified HSD-1 were investigated by cooling curve method and differential scanning calorimeter (DSC) method. The effect of nucleating agent and thickener were deeply researched. The results indicate that the phase change temperature of HSD-1 is 4.2˚C and the latent heat is 318.1 kJ/kg. The modified HSD-1 has good heat stability. With the injection of 0.0567g of PS as the nucleating agent into the HSD-1, the degree of super-cooling decreases by 5˚C. By adding SJ as the thickener, the temperature of the system is stable and no phase separation is observed. These results show that the modified HSD-1 can be used in refrigerated transport equipment.
