摘要
根据固体吸附制冷原理,利用太阳辐射能作为热源,研究了一种新型太阳能冷管。该新型冷管利用硅胶—水作为制冷工质对,通过理论分析计算可以得出:在平均太阳辐射强度为686.1 W/m2,冷凝温度与蒸发温度分别为40℃、10℃的条件下,该冷管在上海地区典型夏季气候中的制冷量与COP在一个循环周期(24 h)分别为524 kJ和0.414。
Based on the principle of solar adsorption which completed the adsorption refrigeration cycle using solar energy, a novel solar cooling tube was developed by silica gel-water work pairs. Through theoretical analysis and calculation： under the conditions of average solar radiant energy 686.1 W/m2, condensing temperature and evaporation temperature was 40℃ and 10 ℃respectively, the solar cooling tube＇ s cooling capacity was about 524 kJ and the coefficient of performance （COP） was about 0.414.
