摘　　要：针对常用太阳能吸附制冷装置采用平板式太阳能吸附集热器存在的不足,如焊接密封工艺要求高,不能应用氨工质,工程应用检修要求复杂等,本文构造了套管型太阳能吸附集热器,它除了可有效克服上述问题外,还可采用玻璃真空管等工艺取代发泡材料进行热防护处理,而且还能用于以真空系统运行的太阳能吸附制冷系统(采用水或甲醇等为制冷剂)。本文以活性碳-甲醇为工质对,对套管太阳能吸附集热器进行了实验,研究发现,该装置性能与玻璃套管类型,管间距等有关。采用普通型玻璃套管,其性能比平板吸附集热器系统略有下降,但处理工艺比较简单,成本较低,商用前景较好。A novel solar adsorber, which is insulated by a glass tube, has been proposed in this paper. The adsorber is expected to overcome the drawbacks of conventional flat plate solar adsorber, namely, strict requirement on welding, complexity in maintenance and engineering application, etc. Also important is that the working pairs operated not only under the ambient pressure could be used, such as the methanol-carbon, but also above the ambient pressure, such as ammonia-carbon, or ammonia-CaCl2. In this work, the solar adsorber filled with methanol-carbon has been investigated experimentally. It is found that the performance of such adsorber is relevant to the distance of two adjacent tubes, as well as the type of glass insulation. A typical glass tube insulated solar adsorber behaves somewhat worse than a flat plate one, but can be fabricated more easily and in lower cost.
