太阳能热水锅炉的节能潜力和能耗分析

Energy Saving Potential and Energy Consumption Analysis of Solar Hot Water Boilers

阐述了太阳能锅炉系统的组成、工作原理、特点及研究现状,利用动态系统模拟软件（TRNSYS）,对应用在鄂尔多斯达拉特旗的太阳能热水锅炉系统进行模拟计算和热经济性分析。结果表明：在冬季供暖季,当太阳能集热器面积分别为5和8 m^2时,太阳能热水锅炉系统的平均节能率分别为13.50%和18.18%,平均太阳能保证率分别为18.25%和27.79%,其中光照良好一天的节能率分别为36. 32%和50. 98%。与传统热水锅炉相比,太阳能锅炉系统的节能潜力大,能耗量明显降低。

This paper described the composition, working principle, characteristics and research status of the solar boiler system. TRNSYS software was adopted to simulate the solar hot water boiler system and analyze the thermal economy in Dalad Banner. The results showed that the average fractional energy savings were 13.50% and 18.18% when the collector areas were 5 and 8 m^2 in winter heating season. The average solar fraction was 18.25% and 27.79% ,respectively. The fractional energy savings could reach 36.32% and 50.98% with good daylight. Compared with the traditional hot water boiler system, the energy saving potential of the solar hot water boiler system is large and the energy consumption can be significantly reduced.
