Summary

A novel fabrication technique of hard-shell microcapsules (HSMC) containing trimethylolethane hydrate as a phase change material has been tested with double nozzle method. The inner and the outer diameters of the inner nozzle and the inner diameter of the outer nozzle of the double nozzle were fixed at 0.24, 0.46 and 0.8 mm, respectively. The inner/outer flow ratio was changed from 2.50 to 5.00, while the flow rate injected from the outer nozzle was kept constant at 2 ml/h. From the results, it was found that the mean diameter of capsules is 1.58 mm when the flow rate ratio is 2.50. In this case, a reasonable latent heat was also obtained. Thus, it was concluded that the present method for the fabrication of the capsules containing the trimethylolethane hydrate can be a promising method.
