THE OBJECTIVE OF THIS RESEARCH IS TO IMPROVE THE ENERGY EFFICIENCY OF THE COLD-STORAGE ATTAINED CURRENTLY BY ICE-STORAGE SYSTEMS. THE IDEA IS TO USE A CLATHRATE HYDRATE COMPOUND THAT CHANGES ITS PHASE FROM LIQUID TO SOLID AT A TEMPERATURE HIGHER THAN 0 DEGREE. THE SUBSTANCE SELECTED IN THIS RESEARCH IS TETRA-N-BUTYLAMMONIUM BROMIDE (HEREAFTER "TBAB" ). WHEN THE AQUEOUS SOLUTION OF TBAB WITH A MASS CONCENTRATION BETWEEN 0〜40 % IS COOLED, CRYSTALS OF CLATHRATE HYDRATE ARE FORMED AT A TEMPERATURE BETWEEN 0〜12 DEGREE. THE DEPENDENCE OF THE PHASE-CHANGE TEMPERATURE AND THE LATENT HEAT OF PHASE CHANGE UPON THE MASS CONCENTRATION WERE OBTAINE USING A DIFFERENTIAL SCANNING CALORIMETER. AT THE SAME TIME, THE FRACTIONS OF SOLID AND LIQUID PHASES AFTER THE HYDRATE FORMATION AND THE REFRACTIVE INDICES WERE MEASURED. IN ADDITION, MORPHOLOGY OF THE HYDRATE CRYSTALS WERE OBSERVED THROUGH A HIGH-MAGNIFICATION MICROSCOPE, REVEALING THAT THE TYPICAL SHAPE OF THE CRYSTALS IS CYLINDRICAL.

这项研究的目的是提高通过冰镇系统实现的冷藏的能源效率。这个想法是使用杂质水合物化合物，该化合物在高于0度的温度下从液体变为固体。在这项研究中选择的物质是溴化四丁基铵（以下称为“ TBAB”）。当将质量浓度在0-40％之间的TBAB的水溶液冷却时，在0-12度之间的温度下形成杂质水合物的晶体。使用差分扫描量热仪获得相变温度和相变的潜在相位变化对质量浓度的依赖性。同时，测量了水合物形成和折射率后固体和液相的分数。另外，通过高磁化显微镜观察了水合晶体的形态，表明晶体的典型形状是圆柱形的。
