【摘要】：随着微机械加工技术的飞速发展,各种新型微型制冷系统的研发受到了广泛关注,尤其是微型蒸汽压缩式制冷系统的发展最为迅速,有的已成功应用于电子元器件及个体微环境的散热等领域。但是目前而言微型蒸汽压缩制冷系统的能量源仅有锂电池、氢燃料电池和直接使用化学燃料的内燃机三种。为了使系统能量源满足节能环保的要求,将太阳能发电与微型制冷系统结合起来势必成为一种新的机遇。本文首先对当前微型压缩式制冷系统及独立太阳能发电制冷系统的研究状况进行了综述,并设计了微型太阳能发电制冷系统。其次,分析了微型制冷系统的热平衡,测试了系统在晴间多云、多云转阴及蓄电池单独测试三类不同情况下的工作性能,包括太阳辐射强度、环境温度、电压、电流、电功等参数,根据实验结果对比分析了环境温度和太阳辐射强度对系统运行性能的影响。最后,对太阳能电池效率、系统能量分配及系统能量效率进行了分析,并根据实验数据分析结果提出了系统理论模型,同时对系统能量分配的关键问题也给出了优化。根据研究中发现的一些问题和不足,提出了后续研究和改进的方向。
[Abstract]:With the rapid development of micro-machining technology, the research and development of various new micro-refrigeration systems have received extensive attention, especially the development of micro-steam compression refrigeration system is the most rapid. Some have been successfully used in the field of electronic components and heat dissipation in individual microenvironments. However, at present, the energy source of micro-steam compression refrigeration systems is only lithium batteries. Hydrogen fuel cells and internal combustion engines that use chemical fuels directly. In order to make the energy source of the system meet the requirements of energy conservation and environmental protection, The combination of solar power generation and micro refrigeration system is bound to be a new opportunity. Firstly, this paper summarizes the current research status of micro compression refrigeration system and independent solar power generation refrigeration system. Secondly, the heat balance of the micro refrigeration system is analyzed, and the performance of the system under three different conditions of sunny cloud, cloudy to negative and battery testing is tested. It includes solar radiation intensity, ambient temperature, voltage, current, electric power and so on. Based on the experimental results, the effects of ambient temperature and solar radiation intensity on system performance are compared and analyzed. The system energy distribution and system energy efficiency are analyzed, and the system theoretical model is proposed based on the experimental data analysis results. At the same time, the key problems of the system energy distribution are optimized. The direction of further research and improvement is put forward.
