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, diurnal storage media operated on a daily basis at the temperate range between 10 and 20 °C are the most desirable. This paper will present the 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 was cooled to 5 °C and heated to 25 °C cyclically in a storage tank of 230 l, and it was observed that full latent heat storage can only be realized at around 7 °C due to supercooling, and the effective cooling storage capacity at the cooling temperature range between 5 and 18 °C are obtained, which can be used to realistically estimate cooling storage capacity with various natural cooling schemes.
