固态制冷剂的性能研究

Studies on Solid-Solid Inorganic Compounds as a Refrigerant

对单组分无机盐溶质NH4SCN,NH4Cl及混合组分无机盐溶质KNO3+NH4NO3、KNO3+NH4Cl、KNO3+NH4SCN、NH4Cl+NH4NO3分别与结晶水合物Na2CO3.10H2O混合的冷效应进行了实验研究,得出最佳混合比和最大制冷温差,并将制冷效果与无机盐溶质与水混合时的最佳制冷效果进行对比。

The freezing effect of single inorganic salt NH4SCN , NH4 Cl and mixed inorganic salt KNO3 ＋ NH4NO3 , KNO3 ＋ NH4 Cl , KNO3 ＋ NH4 SCN , NH4 Cl ＋ NH4 NO3 nfixed with Na2 CO3 · 10H2O are studied experimentally in the present paper. The optimal proportion between the solute salt, and the max temperature difference of the freezing effect when the inorganic salt mixed with Na2 CO3· 10H2O and H2O respectively are discussed.
