Abstract：This article experimented the thermal conductivity of micro phase change materials suspension(MEPCMs) and open phase change materials suspension(PCMs) with 18℃ phase transition temperature by transient hot wire source measurement tech-nology,analyzed the influence of temperature and concentration on the thermal conductivity,and analyzed the two phase change materials with DCS tester to obtain the latent heat capacity. The results show that the thermal conductivity of these two phase change materials suspension will firstly increase then decrease with ascendant temperature and it will increase with the decrease of the concentration. The thermophsyical properties of these two phase change materials are compared, the result shows that the mi-croencapsulated phase change materials have better thermophysical properties,capable to increase the running efficiency and stabil-ity of the solar powered air conditioning system.
