The improvement of the useful energy through the conversion of electric power into thermal energy(P2H) became one of the important issues. Among them, a method to reduce supercooling is being sought as a means to effectively store ice as a ice thermal energy storage system. This study investigated the relationship between the degree of supercooling and the particles through a cooling experiment of pure water containing additives (silica powder, kaolin powder) to understand the effect on the release of supercooling. The sample was constructed by putting each different additives (silica or kaolin) in a test tube and connecting a K-type thermocouple. The sample thus prepared was cooled through a low-temperature thermostat. As a result, it was confirmed that the particle type affects the degree of supercooling.
