Performance of a long-term latent heat thermal energy storage unit which uses supercooling was experimentally investigated. The volume of the storage tank is 53 a and the tank has 31 capsules of phase change material (PCM), disodium hydrogenphosphate dodecahydrate. The heat of fusion of the PCM in the unit is 9.1MJ. The result of the experiments shows that the storage unit can control the nucleation of the supercooled PCM after 204 days from the melting operation. From the result of the storage operation between 22℃ to 66℃, the sensible heat of the unit was released into the room during storage period but the latent heat remained in the unit, and 49 % of the initial stored heat in the temperature range was recovered by the nucleation operation.
