에탄올이 첨가된 TMA포접화합물의 냉각특성 = The Study on Cooling Characteristic of TMA Clathrate with Ethanol

다국어 초록 (Multilingual Abstract)

The purpose of this study is to investigate the propriety of TMA clathrate as a cold storage medium. Particularly, this is to examine the extent of subcooling improvement when the additives are added to the TMA clathrate, because water used cold storage material has low phase change temperature and subcooling. This study has been analyzed and compared with TMA 30 wt% clathrate how phase change temperature, subcooling and specific heat in the various concentrations are changed. This results view to be improved phase change temperature and subcooling of TMA 30wt% as a cold storage medium, when it had some additive. Additionally, it is found that the additive must be controlled under available solution limit and study for new additive must be lasted to know its effect.
