研制了以太阳能为能源，以复合吸附剂/水为工作对的新型弯曲太阳能冷却管，并对其进行了实验研究。实验结果表明，白天太阳辐射约为20.5MJ/（d·m2）时，吸附床温度可达223℃，冷凝温度约为60℃，脱附质量约为168.1g。夜间将吸附床层温度降至52℃左右，蒸发器温度降至12℃左右，制冷功率在14W ~ 2W之间变化，总制冷量约为378 kJ。在夏季和秋季太阳辐射17 ~ 22 MJ/（d·m2）时，新型弯曲太阳能冷却管可提供300 ~ 390 kJ的制冷量，COP约为0.23 ~ 0.25。
The novel bend solar cooling tube,which uses solar light as energy and compound adsorbent/water as working pair,was made and experimental studied in this research.The experimental results show that,when the solar radiation was about 20.5MJ/(d·m2) at the daytime,the temperature of adsorbent bed could reached to 223℃,the condensation temperature was about 60℃,the desorbent mass was about 168.1g.In the nighttime,the adsorbent bed temperature was cooled down to about 52℃ and the evaporator temperature was about 12℃,the refrigeration power was varied from 14W to 2W,the total cooling capacity was about 378 kJ.At the solar radiation was between 17-22 MJ/(d·m2) in the summer or autumn,the novel bend solar cooling tube could supply cooling capacity about 300-390 kJ and the COP is about 0.23-0.25.
