本文介绍了一个双床，活性炭纤维（ACF）-乙醇吸附式制冷机，这已经研究了由相同的作者[B. B.萨巴岛EI-Sharkawy，A.查克拉博蒂，S。Koyama，活性碳纤维-乙醇吸附式制冷机研究：第一部分-系统描述和建模，国际制冷杂志，提交出版]。这种创新的吸附式制冷机，其中A-20型沥青基ACF被用作吸附剂，有效地利用了温度在60和95摄氏度之间的低温废热源沿着环境温度下的冷却源。我们发现，无论初始质量分布如何，ACF-乙醇吸附式制冷机都能够在三个半循环或1890 s内达到相同的循环稳态。仿真结果表明，在驱动源温度为80 ~ 85 ℃时，制冷机的性能系数最佳，适合于低温余热回收。(c)2006年Elsevier Ltd和IIR。All rights reserved.
This article presents the performance evaluation of a two-bed, activated carbon fiber (ACF)-ethanol adsorption chiller, which has been studied on the basis of the transient modelling developed by the same authors [B.B. Saba, I.I. EI-Sharkawy, A. Chakraborty, S. Koyama, Study on an activated carbon fiber-ethanol adsorption chiller: Part I - system description and modelling, International Journal of Refrigeration, submitted for publication]. This innovative adsorption chiller, where pitch based ACF of type A-20 is taken as the adsorbent utilizes effectively the low-temperature waste heat sources of temperature between 60 and 95 degrees C along with a cooling source at ambient temperature. We have found that, regardless of the initial mass distribution, the ACF-ethanol adsorption chiller is able to achieve the same cyclic-steady-state within three half cycles or 1890 s. Simulation results show that the optimum COP values are obtained at driving source temperatures between 80 and 85 degrees C and makes this chiller suitable for low-temperature waste heat recovery with relatively higher performance.
