Experiment Study on Thermal Conductivity of Microcapsule Phase Change Suspension Applied to Solar Powered Air Conditioning Cold Storage System

Abstract This paper presents a novel thermal conductivity measurement of microcapsule phase change materials (MEPCM) suspension. MEPCM suspension applied to solar powered air conditioning cold storage system can significantly save electric energy and improve the system efficiency. The experiment shows that MEPCM suspension’ heat transfer capability is better than conventional cooling medium pure water. The best thermal performance of MEPCM is in the certain temperature range 16℃~17.3℃. The 30% concentration MEPCM suspension have the maximum thermal conductivity. The optimization conditions for solar powered air conditioning cold storage system is further proposed. The results of this paper provides a useful guidance of the design and improvement about solar powered air conditioning cold storage system.
