用于冷链运输的复合相变蓄冷剂主储能剂研制
|
摘要
研制了一种用于冷链运输的三元复合相变蓄冷剂的主储能剂。以有机物甘露醇(C6H14O6)水溶液作为主储能剂,无机物氯化钾(KCl)水溶液为相变温度调节剂,经充分混匀,用差示扫描量热仪研究主储能剂的热物性,并测试其T-t曲线来判断其稳定性。结果表明,当C6H14O6/KCl溶液的浓度比(mol/L)为0.6∶0.2,且水溶液体积按1∶1混合时,该复合物可以达到相变潜热在290 J/g以上,Onset温度在-6~-4℃的主储能剂要求。测得Onset温度为-5.1℃,相变潜热为296.3 J/g,且无分层,无过冷,无相分离现象。主储能剂的原料无毒无害,价格便宜易得。其化学性能稳定,能长期反复使用,可以大规模应用于低温物流、冷链运输等领域。
A new formula of composite phase change coolant for cold chain transportation was developed with three different materials. The organic mannitol solution was used as the main body of the energy storage agent and inorganic potassium chloride solution was used as regulators of phase transition temperature, the thermal properties of the composite coolant were analyzed by DSC and stability was judged by T-t curses. The results show that the new formula can meet the requirements of main energy storage agent with 290 J/g or higher latent heat, and phase transition temperature between-6 ℃ and-4 ℃. When the molal concentration of C6H14O6 to KCl is 0.6 to 0.2, and volume is 1 to 1, the phase transition temperature and the latent heat is-5.1 ℃ and 296.3 J/g. Furthermore, there is no super-cooling and separation phenomenon. All of the materials of the main storage agent are safe, cheap, easily available and stable, so the new main storage agent can be widely used in the field of cryogenic and cold chain transportation.
