Entropy Values of Lithium Bromide-Water Solutions and Their Vapors 溴化锂水溶液及其蒸汽的熵值
尽管溴化锂水溶液及其蒸汽的焓是可用的(1和2),但据报道,哈罗德·洛厄尔4只计算了一些熵值,并指出3需要重新评估这些溶液的熵。本文利用与蒸汽压、活度系数和比热容有关的最佳实验数据,计算了溴化锂水溶液在a DC至200 DC温度范围内的熵值。这些数值可用于对使用溴化锂-水混合物的吸收式制冷系统进行第二定律分析。引文:ASHRAE交易,第82卷,第2部分,华盛顿州西雅图
Although enthalpies of lithium bromide-water solutions and their vapors are available (1 and 2), only some values of entropy are reported 3 to have been computed by Harold Lower4, and it is stated 3 that it would be desirable to re-evaluate the entropies of these solutions. In this paper the values of entropy of lithium bromide-water solutions have been computed over the temperature range a DC to 200 DC, using the best available experimental data p~rtaining to vapor pressures, activity coefficients and specific heat-capacities. These values can be useful in making second law analysis of absorption refrigeration systems using a lithium-bromide-water combination.
