A Study on Cooling Characteristics of Low Temperature Thermal Storage Material with Additives

첨가제를 첨가한 저온축열물질의 냉각특성에 대한 연구

The objective of this study is to investigate the effect of supercooling repression on the clathrate compound by adding additives. For this purpose, phase change temperature and supercooling were measured when additives added to TMA30wt% clathrate for heat source temperature of $-6^{\circ}C$. The experimental results show that the phase change temperature with the chloroform of 0.1wt% is higher by $0.3^{\circ}C$ than TMA30wt% and the supercooling with the surfactant 0.1wt% is reduced by $9.2^{\circ}C$.
