    Adsorbent bed with new structure based on solar adsorption refrigerator

    • 摘要: 该文对新型吸附床的结构做了设计说明,采用太阳光直接照射吸附床加热活性炭,用蜂窝状结构增强吸附床的传热。结果表明,直接加热活性炭可使吸附床内部在接受13.59MJ的能量后最高温度可达到117℃,使用蜂窝状传热结构吸附床内的最大温差小于5℃,实测系统COP(系统制冷性能系数)为0.157。通过对吸附床建立数学模型,对吸附床内的温度随太阳辐射能变化建立了计算模拟。

       

      Abstract: In this study, a new solar solid adsorption ice maker with honeycomb adsorbent bed and activated carbon-methanol pair was developed and examined. Experimental results showed that the directly solar-irradiated adsorbent bed could effectively increase the bed temperature, and a maximum bed temperature of 117℃ was measured. Results also indicated that the temperature difference between the front and back surface of the bed was less than 5℃, and this result showed that the adsorbent bed was excellent in the heat transfer. Experimental results also indicated that the COP of the system was related to climatic conditions as observed by other researchers, and maximum COP of 0.157 was found during the period of experiments.
