TMA 농도에 따른 저온축열물질의 과냉각 특성에 대한 연구

다국어 초록 (Multilingual Abstract)

This study is investigated the supercooling characteristics of the TMA-water clathrate compound including TMA (Tri-methyl-amine, (CH3)3N) of 20~25 wt% as a low temperature latent heat storage material at -5℃, cooling source temperature. The results showed that as the concentration of TMA is increased, phase change temperature is increased, the supercooling and retention time of liquid phase are decreased. Especially, low temperature latent heat storage material containing TMA 25 wt% has the average of phase change temperature of 5.8℃, supercooling degree of 8.0℃, retention time of liquid phase for 10 minutes in the cooling process. Phase change temperature higher than that of water and inhibitory effect against superrcooling can be confirmed through experimental study on cooling characteristics of TMA-water clathrate compound. This can lead to shorten refrigerator operation time of low temperature thermal storage system and improve efficiency of refrigerator COP and overall system.
