Abstract

Ice storage is currently the dominant cooling energy storage method. To more effectively utilize natural, renewable cooling sources, such as evaporative cooling and sky-radiative cooling, diumal storage media operated on daily basis at the temperate range between 10 and 20 °C are the most desirable. In the paper, we will present our experimental investigation of microencapsulated paraffin slurry as cooling storage media for building cooling applications. The water slurry of microencapsulated n-hexadecane with a melting temperature of 18 °C were cooled to 5 °C and heated to 25 °C cyclically in a storage tank of 230 litre, and it was observed that full latent heat storage can only be realized at 13 °C due to supercooling, and the effective cooling storage capacity at the cooling temperature between 5 and 18 °C are obtained, which can be used for cooling storage system design with various passive cooling possibilities.
