PURPOSE:To obtain a compact latent heat accumulation utilizing cooling system having small icing power by composing it of a granulating unit for discharging particular latent heat accumulation material, refrigerant circulating system for cooling the material, a heat accumulation utilizing system for feeding the material to a heat exchanger, and a recovery system for recovering the material to the granulating system. CONSTITUTION:When liquidlike latent heat accumulation material 18 is poured in a cylinder 7 while refrigerant 2 cooled by a chiller 4 is circulated in a refrigerant circulation system by a circulation pump 3, and small particles of the material 18 are started to be formed at the end of a nozzle 8. When pressure is continuously applied to the piston 6, the particles increased to certain degree are separated from the nozzle. Liquid particle latent heat accumulation material 10 cooled with the refrigerant 2 becomes solid particular latent heat accumulation material 11, and stored in a storage unit 13 in the circulation system. The material 11 is fed into the system by the operation of a circulation pump 17 to dissipate heat in a heat exchanger 14 to become liquid to be fed to a downstream side. The material 18 fed to a storage unit 20 is sequentially recovered by the piston pressure via a recovery tube 16 from above the unit 20. |
