摘要
针对单层玻璃盖板平板型太阳能集热器、双层玻璃盖板平板型太阳集热器进行了热性能对比实验。结果显示:在28.7℃和41.4℃这2种工质进口温度下,单层玻璃盖板平板型太阳能集热器的瞬时效率比双层玻璃盖板平板型太阳能集热器的高,而在54.2℃和66.9℃这2种工质进口温度下,双层玻璃盖板平板型太阳能集热器的瞬时效率比单层玻璃盖板平板型太阳能集热器的高。单层玻璃盖板平板型太阳能集热器的瞬时效率截距比双层玻璃盖板平板型太阳能集热器的大;双层玻璃盖板平板型太阳能集热器的热损系数比单层玻璃盖板平板型太阳能集热器的小。
This paper presents a comparison of the thermal performance between flat plate solar collectors with single-layer-glass cover and double-layer-glass cover.The results show that at the inlet temperature of working fluids of 28.7℃and 41.4℃,instantaneous efficiency of the single-layer-glass cover flat plate solar collector is higher than that of flat plate solar collector with double-layer-glass cover,while it is lower at 54.2℃and 66.9℃.Comparing with that of flat plate solar collector with double-layer-glass cover,the instantaneous efficiency intercept of flat plate solar collector with single-layer-glass cover is greater and the heat loss coefficient is larger.
