摘要:
对平板型太阳能集热器表面积尘进行测试,分析了积尘对其系统性能的影响。研究表明,在同等外界条件下,以集热器表面积尘量11.58 g?m-2为例,系统得热量显著下降,集热效率下降了17.40%。通过试验测试,分析了松散和粘结两种积尘状态下不同积尘量对系统集热性能的影响。在具有相同积尘量的条件下,粘结状态积尘对集热性能的影响高于松散状态积尘。在积尘初期系统集热效率下降速度较快,而后逐渐变缓。该研究对太阳能集热器积尘进行定期清洁、提高换热效率具有参考意义。
Abstract:
Solar collectors are the key components of solar collector system, which thermal performance determine the efficiency of solar heating system. In order to investigate the effect of natural dust on the performance of flat-plate collector, he filed tests are performed on the solar collectors under the same circumstance with the dust and cleaning conditions of the glass cover surface. The results show that, comparing with the cleaned collector, a dust density of 11.58 g·m-2 corresponds to a 17.40% reduction in thermal collection performance. Furthermore, contrast test is conducted to illustrate the effect of different dust forms on collector performance. With loose dust solar collector, the collector with cohesive dust exerts bigger influence on thermal performance in solar heating system. It is found that the collector performance decreases fast at the beginning of the dust accumulation and then gradually slows down. This study can provide a reference in formulating cleaning strategies of collector and improving the heat transfer efficiency of solar heating system
