摘　　要：介绍了太阳能冷管应用吸附制冷的运行机理并建立了太阳能冷管运行周期的数学模型,求解得出吸附 床温度、中芯管壁温度、蒸发器壁面温度等参数随时间变化的关系。进行了太阳能冷管的实验研究,在环境温 度为:36-28℃,冷管周围风速:0．5m／s的条件下,太阳能冷管制冷持续时间为13h,冷管蒸发器温度最低可达 18℃,实验测量值与理论计算结果吻合的较好。A solar cooling tube is a cooling unit which can make a complete refrigeration cycle in a single tube. The mechanism of solar cooling tube was described in this paper. Based on the energy conversion in the solar cooling tube and adsorption theory, a mathematical model for solar heating and adsorption refrigeration was established to simulate the operation in the solar cooling tube in one day. The variation of temperature of the solar collector, adsorbent bed, central glass tube and refrigerator was calculat...
