本文提出了一种适用于太阳能农村住宅空间供暖系统的创新的多贯穿流动的微通道板阵列的分析和实验研究相结合。与传统的一对一连接的面板阵列相比，该阵列可以显著减小头部和真实的面板之间的温差，从而提高整体太阳能热效率和能量效率比（EER）。研究方法包括理论分析、实验测试、模型验证和系统优化。结果表明，该分析模型对多通流微通道板阵列的性能预测具有较好的精度，误差小于10%。就阵列的结构和尺寸而言，10块板和5个流动转弯被认为是最受欢迎的选择。在操作期间，降低流体的流速导致板阵列的EER增加。通过将一对一连接模式转换为多通流模式，太阳能电池板阵列的整体太阳能热效率提高了约10%，其能量效率因子（EER）降低了80%。该研究提出了一种新型的太阳能电池板阵列，可以很好地应用于太阳能热系统，从而为全球范围内节省化石燃料能源消耗和减少碳排放做出了重大贡献。
This paper presents a combined analytical and experimental study of an innovative multiple-throughout-flowing micro-channel-panels-array applicable to a solar-powered rural house space heating system. This array, compared to the traditional one-to-one-connection panels-array, can significantly reduce the temperature difference between the head and real panels and thus increase the overall solar thermal efficiency and energy efficiency ratio (EER). The research methodology covers the theoretical analysis, experimental testing, model validation and system optimization. It is found that the analytical model has a good accuracy in predicting the performance of the multiple-throughout-flow micro-channels-panels-array, giving a discrepancy of less than 10%. In terms of the configuration and sizes of the array, 10 pieces of panels with 5 flow turns is regarded as the most favorite option. During the operation, decreasing flow rate of the fluid led to the increased EER of the panels-array. By converting the one-to-one-connection mode into the multiple-throughout-flowing mode, the overall solar thermal efficiency of the panels-array increases by around 10% and its energy efficiency factor (EER) decreases by 80% respectively. The research has addressed a novel solar-panels-array that can be well applied to solar thermal systems, thus making a significant contribution to the saving of fossil fuel energy consumption and reduction of carbon emission on global scale.
