Purpose of this sturdy is to clarify the heat transfer phenomena of inorganic hydrate thermal energy storage capsule in a case of heating and cooling the capsule periodically. When the inorganic hydrate is absorbing and discharging heat periodically,heat transfer phenomena is dominated not only by thermal conduction but also by heat absorbed during melting of crystal, heat discharged during forming of crystal nuclei, crystal growth and so on. It also depends upon the highest temperature whether it is higher than the saturation temperature or not. Those phenomena can be observed in a capsule at the same time in different locations. In this report, analytical method to solve such a complex system is introduced. Gelled Glauber Salt is used as PCM. The highest and the lowest temperature of the outer surface of the capsule and rate of changing of the temperature are set to a certain value, and the experiment was carried out. The parameters used in the analysis was obtained to fit with the experimental results. Then, experiments and analysis were carried out under various conditions determined by changing the setting temperature or its cycle. The analytical results and the experimental results agreed well with each other. Hence, the adequancy of the analytical method and the heat transfer phenomena were clarified.
