摘要：

Dispersing high-conductivity nanomaterials into phase change materials (PCM) of latent heat thermal energy storage systems (LHTESS) is expected to solve the problem of poor thermal conductivity of PCMs. Accordingly, several metals, metal oxides and non-metals are employed as nanoadditives for PCMs by researchers. Besides thermal conductivity of PCMs, the other thermo-physical properties are also altered by nanoadditives. This paper provides comprehensive information on the effects of nanoadditives on the thermo-physical properties of PCMs through a critical review of related published works. The modified properties ultimately determine the charging and discharging rates of LHTESS. The extent of improvement in the thermal performance and the related issues are addressed. Further, the theoretical/empirical models developed so far for the evaluation of thermo-physical properties are deliberated. [GRAPHICS] .
