混合溶剂盐化学制冷剂的研究

Studies of Chemical Refrigerant Containing Mixed Solvent Salt

研究表明 ,用 Na2 CO3· 1 0 H2 O和 Na2 HPO4· 1 2 H2 O混合物作溶剂盐较单独使用 Na2 HPO4·1 2 H2 O或 Na2 CO3· 1 0 H2 O作溶剂盐 ,其制冷效果更佳 .适当增加混合溶剂盐中 Na2 HPO4· 1 2 H2 O的量 ,可延长制冷时间 ,降低制冷温度 .

The studies indicate that the refrigerating effect of the chemical refrigerant containing the mixed solvent salt of Na 2CO 3·10H 2O and Na 2HPO 4·12H 2O is better than that containing a singal solvent salt. Increasing the Na 2HPO 4·12H 2O content in the refrigerant properly can prolong the refrigerating time and lower the refrigerating temperature.
