Study on Dispersion Stability Characteristics of TiO₂ Nanoparticles in PCM for Use in Cold Storage Air-Conditioning

Abstract:

A new organic phase change materials (PCM) for cool storage was developed for use in cold storage air-conditioning. The thermal properties of the new organic PCM were measured with a differential scanning calorimeter (DSC). To improve the thermal conductivity of the new organic PCM, the further research of using nanocomposite technology to the organic PCM SSW-4 was made. The effects of nanoparticles concentration on dispersion, ultrasonic time and consistence of dispersant in the best ultrasonic time on the dispersion were investigated by experiment. The results showed that the thermal conductivity of the nanocomposite PCM TiO₂ /SSW-4 increased by approximately 16.27% compared to that of the organic PCM SSW-4. The best dispersion condition of preparation for TiO₂ /SSW-4 was confirmed.
