介绍了太阳能冷却管的结构和性能的研究进展.真空集热器和选择性涂层的使用，以提高太阳能吸收率，减少散热。采用固化复合吸附块提高吸附剂床层的吸附能力和传热性能。脱附动力学的实验研究表明，真空度对脱附速率的影响有所改善。介绍了一种太阳能冷管制冷机模型。因此，一种新型的多功能太阳能冷却管，这是设计，以提供加热和冷却同时进行，进行了试验。其制冷系数约为0.193，制热制冷综合性能系数约为0.692。
The research and advancement on the structure and performance of a solar cooling tube were presented. Evacuated solar collector and selective coatings are used to enhance the solar absorptivity and decrease the heat dissipation. Solidified composite adsorption block is used to improve the adsorption capacity and the heat conduction of the adsorbent bed. The experimental investigation of desorption dynamics of the tube indicates the improvement of vacuum in affecting desorption rate. A model refrigerator of the solar cooling tube was also described. Consequently a new kind of multifunction solar cooling tube, which is designed to supply both heating and cooling simultaneously, was tested. Its cooling coefficient is about 0.193 and the whole performance coefficient of heating and cooling is about 0.692.
