本文综合介绍了吸收式制冷机制冷剂——吸收剂的物理性质。制冷剂——吸收剂可按制冷剂分为四类,即以水、醇、氨、氟利昂为制冷剂,分别配以不同的吸收剂。介绍了根据试验数据绘制的图表。目前虽然建议采用的工质较多,但实际可用的还只有NH_3-H_2O和H_2O-LiBr两种,其他几种工质还未超出试验研究范围。作者认为铬酸锂(Li_2CrO_4)虽然广泛用作缓蚀剂,但是一种有害物质,应尽量避免使用。文中推荐Li_6(Mo_7O_(24))·12H_2O、COBRATEC99、NHCH:NCH:CH等作为缓蚀剂,效果较好。参考文献89篇。
This article presents the physical properties of refrigerant-absorbent for absorption chillers. Refrigerant - absorbent refrigerant can be divided into four categories, that is, water, alcohol, ammonia, Freon as the refrigerant, respectively, with different absorbers. Describes charts based on experimental data. At present, although more working fluids are recommended, only two kinds of NH_3-H_2O and H_2O-LiBr are actually available, and the other working fluids have not exceeded the scope of the experimental study. The author believes that although lithium chromate (Li 2 CrO 4) is widely used as a corrosion inhibitor, a harmful substance should be avoided as far as possible. The article recommended Li_6 (Mo_7O_ (24)) · 12H_2O, COBRATEC99, NHCH: NCH: CH as a corrosion inhibitor, the better. Reference 89 articles.
