根据溴化锂吸收式制冷机吸收器中传热传质的物理模型和数学模型，通过计算分析了吸收器的布置方式和溶液再循环倍率对其吸收性能的影响，认为在所计算的三种布置方式中，以冷却水下进上出方式的总吸收效果最好，出液浓度和温度最低；计算结果还表明，溶液再循环倍率越大，吸收器的吸收性能越差，所以在满足喷淋密度的情况下应尽可能地减小溶液再循环倍率。
According to the physical model and mathematical model of heat and mass transfer in the absorber of lithium bromide absorption chiller, the influences of absorber arrangement and solution recirculation ratio on the absorption performance are calculated and analyzed. It is considered that in the three arrangements , The total absorption effect by the cooling water in-and-out mode is the best, and the solution concentration and the temperature are the lowest. The calculation results also show that the larger the solution recycling rate is, the worse the absorption performance of the absorber is. Therefore, when the spray density Should be as much as possible to reduce the solution recycling rate.
