中文摘要: 针对目前太阳能吸附制冷系统中吸附材料对循环工质的吸附能力不足,和固定式吸附床热、质传递速率较低的情况,研制高吸附量的FAM-ZO2型沸石吸附材料,和旋转式双效/多效组合式吸附床,实现夏季白天连续吸附空调的目的。采用替代化学反应方法,以磷酸盐和铝酸盐为原料,制取疏水性的、中性不带电荷的、AlPO质的沸石分子筛,使其吸附变化量达到Y型沸石或硅胶的3~4倍;研究吸附床内加热/冷却流体通道的优化形式,和加热管基材与AlPO基型沸石的一体化制作技术,有效减小接触界面上的传热热阻;研究利用太阳光直接照射的脱附方法;利用太阳辐射能与背阴环境存在热能品位差异的客观条件,研制两个或多个吸附构件协同工作的、集太阳能集热/吸附为一体的、能够交替吸附/脱附的旋转式吸附床;优化室内蒸发器的结构形式。通过理论分析、数值模拟和实验测试手段相结合的技术路线,达到太阳能吸附空调系统COP明显改善的目的。

英文摘要: Towards the problems of low adsorption ability of the material and poor heat and mass transfer in the solar adsorption cooling system, the project will develop new type zeolite of FAM-ZO2 as adsorption material and dual/multiple conjugate-working bed to realize continuous cooling purpose in daylight of summer. With the substitute chemical reaction, the sort of zeolite molecular sieves with hydrophobic and neutrally charged characteristics will be made from phosphate and aluminate. The adsorption variation of the new material is possibly 3~4 folds of the Y-type zeolite or silicon gel. In addition, it is also focused on the study of the optimization of the passage structure in the adsorption bed for cooling / heating purpose. To reduce efficiently the contact thermal resistance along the bounder of the heating/cooling tube and the adsorbents, the consolidating method to unite the tube wall and the AlPO-based zeolite will be investigated. The desorption way with usage of the sunlight directly onto the bed will be paid attention. Further more, emphasis is also laid on the analyses and realization of the rotary adsorption bed, which is composed of two or more sectional beds, acts as solar energy collector as well as adsorbents, and adsorbing/desorbing alternatively. In addition,the optimization of the evaporator will
