Abstract |
This study investigated the improvement effect of a small portion of surfactant on the supercooling and the phase change temperature of TMA 30wt% clathrate compound when surfactant is added to the clathrate compound. The experiments are carried out under various conditions; the concentration of additive ranges between 0.08~0.12wt% and the temperature of heat source ranges between -8 and -6℃. The experimental results show that the phase change temperature with the surfactant of 0.1wt% is lower by 1℃ than TMA 30 wt% and the supercooling is reduced by 10℃. |
