摘　　要：根据吸附式制冷的基本原理，利用太阳能辐射作为热源，研究了在一种新型太阳能吸付式制冷器。该新型弯曲式太阳能冷管采用吸附床整体成型技术，利用复合吸附剂-水作为工质对。实验结果表明：该冷管在太阳能辐射量为20．5MJ／（d·m^2）时，吸附床在白天最高温度达到223℃，最高冷凝温摩约为60℃，整个白天脱附出制冷剂168．1g；在夜间时，吸附床温度可以降至52℃左右，最低的蒸发温度为12℃左右，制冷功率从最高14W左右下降至次日晨2W，制冷量约为378kJ。在夏季、秋季太阳能辐射量为17—22MJ／（d·m^2）之间时，该冷管制冷量为300—390kJ，制冷系数COP为0．23—0．25。The novel bond solar cooling tube, which uses solar light as energy and compound adsorbont/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 · m^2 ） at the daytime, the temperature of adsorbent bed could reached to 223℃, the condensation temperature was about 60℃ , the desorbent mass was about 168. lg. 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 · m^2 ） 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.
