| Research Abstract |
In order to use the exhaust heat and the solar heat for the heating and the hot water supply inside house, it is necessary to develop the latent heat storage material which has the good flow characteristics into pipe from outside to inside. In this study we investigated the possibilities of latent heat storage materials through carrying out the three following experiments. (1) Development of highly-concentrated slurry of latent heat storage materials, (2) Examination of heat storage materials using the liquid-solid-liquid phase change of nitrate, (3) Examination of sodium chloride as an absorber of absorption heat pumps. In the experiments of (2) and (3), there was a problem about the sudden fluidity drops of accompanying crystallization of heat storage material. But the solution of sodium sulfate 10 hydrates which added the surfactant (1), had the high fluidity for even under the condition of highly-concentrated slurry.
