摘要
通过研究不同无机盐对单一无机盐水溶液最低共熔点的影响,结果表明:添加无机盐可降低单一无机盐水溶液的最低共熔点;添加5%无机盐Kx的10.9%KNO3水溶液,其最低共熔点从-2.5℃下降到-5.4℃,相变潜热为307.16kJ/kg,可以满足铁路冷藏车共晶液的设计要求。
It was studied about the effect to lowest eutectic point of unique inorganic salt solution by adding other inorganic salts. The result shows that the lowest eutectic point of unique inorganic salt solution falls by adding other inorganic salt. By adding 5% inorganic salt Kx to 10.9% KNO3 solution, its lowest eutectic point falls from -2.5℃to -5.4℃, and its phase transition enthalpy can reach to 307.16 kJ/kg. As an eutectic' liquid in railway refrigerated lorry the solution can meet the requirement on design.
