【摘要】：在能源短缺与大气环境问题日益尖锐的大背景下，吸附式制冷以其利用太阳能等可再生自然能源与非氯氟烃类自然制冷工质的独特优势引起广泛关注与研究。但是，太阳能吸附式制冷目前还未能在实际工程中推广应用，主要原因在于其制冷效率与系统保证率较低。首先利用HottelModel数学模型对武汉地区夏季典型日的逐时太阳辐照强度进行计算，用实验数据验证了其可信度，并使用它预测了武汉地区一年的太阳辐照强度情况。在对现有吸附工质对、传热性能强化技术以及连续循环方式综合考虑的前提下，，以活性炭-甲醇为吸附工质对优化设计了一种以太阳能冷管为基础的适用于小型民用建筑空调/冷藏新型复合管式太阳能吸附制冷系统，以小型冷藏库为例对其进行了系统选型匹配。基于simulink平台利用集总参数法建立了复合管式太阳能吸附制冷系统仿真数学模型，通过对仿真系统一天内制冷与空调两种工况实时模拟，系统地分析了循环周期、回热回质时间、解吸热水温度、冷却水温对复合管式吸附制冷系统性能的影响，对其运行特性进行了分析和优化。
[Abstract]:In the background of energy shortage and atmospheric environmental problems , adsorption refrigeration has attracted extensive attention and research using the unique advantages of renewable natural energy such as solar energy and non - CFC natural refrigeration working substance . However , solar adsorption refrigeration is not widely applied in practical engineering , mainly because its refrigeration efficiency and system guarantee rate are low .

In this paper , the solar radiation intensity is calculated by using the Hottel Model mathematical model , and the reliability is verified by using the experimental data . The simulation model of the composite pipe type solar adsorption refrigeration system based on the solar cold pipe is designed based on the experimental data . The simulation model of the composite pipe type solar adsorption refrigeration system is established by using the lumped parameter method . The influence of the cycle period , the heat recovery time , the desorption hot water temperature and the cooling water temperature on the performance of the composite pipe type adsorption refrigeration system is analyzed and optimized by using the lumped parameter method .
