PROBLEM TO BE SOLVED: To early release a supercooling degree of a latent heat thermal storage substance in a capsule by preventing a phase separation of the substance in the capsule by improving a heat transfer and thermal storage performance at a low cost. SOLUTION: The thermal storage capsule 1 seals the latent heat thermal storage substance therein and stores a heat exchanged with a heat conveying fluid 2 flowing in a circumference. The capsules 1 are easily uniformly dispersed in the fluid 2 by setting its specific gravity equal to that of the fluid 2. Thus, the capsules 1 are easily distributed in the fluid 2 without deviation. A wide heat transfer area is assured to easily efficiently heat exchange with the fluid. A capsule shape which flows, rotates and vibrates by flowing of the fluid 2 is formed. Thereby, a turbulence is generated in both the flows of the latent heat thermal storage substance liquid inside the capsule and the heat conveying fluid out of the capsule. The phase separation of the thermal storage substance is prevented, the supercooling degree is lowered, a heat transfer coefficient between the inner wall surface of the capsule and the thermal storage substance liquid is improved and a heat transfer coefficient between the outer wall surface of the capsule and the conveying fluid can be improved. |
