《压力容器介质手册》这本书里应该有液氨换热器用不锈钢的就行啊，如果想省点，壳层用Q235-B（液氨走管层）液氨饱和蒸汽压与温度的关系温度℃ 蒸汽压kpa 温度℃ 蒸汽压kpa 温度℃ 蒸汽压kpa 温度℃ 蒸汽压kpa 温度℃ 蒸汽压kpa -40 71.77 -20 190.23 0 429.42 20 857.06 40 1554.20 -38 79.79 -18 207.71 2 462.45 22 913.19 42 1642.40 -36 88.54 -16 226.45 4 497.40 24 972.11 44 1734.00 -34 98.04 -14 246.50 6 534.49 26 1033.90 46 1829.50 -32 108.37 -12 267.93 8 573.60 28 1098.70 48 1929.00 -30 119.55 -10 290.83 10 614.89 30 1166.50 50 2032.50 -28 131.64 -8 315.24 12 658.46 32 1237.40 52 2140.10 -26 144.70 -6 341.23 14 704.41 34 1311.40 54 2251.80 -24 158.79 -4 368.87 16 752.74 36 1389.00 56 2368.20 -22 173.93 -2 398.24 18 803.61 38 1469.90 58 2488.70 。
