摘要
针对北方地区冬季清洁供暖问题,本文提出了一种太阳能毛细管辐射采暖系统方案,该系统应用了一种应用太阳能毛细管顶板辐射采暖系统的3L热隔断屋顶,搭建了太阳能毛细管辐射采暖系统试验台。利用energyplus模拟了建筑热负荷,确定了集热器的面积,比较了使用3L热隔断屋顶和普通屋顶实验室的负荷变化,分析了系统蓄热过程、放热过程及电辅助加热过程。结果表明,使用3L热隔断屋顶的实验室热负荷明显降低,平均热负荷较普通屋顶低0.521 k W。该系统在低负荷建筑下供热安全稳定,室内温度稳定在19℃左右。水箱蓄热能效为22.2%,电辅助加热效率可达到95%。
In view of the problem of winter clean heating in the north,a solar capillary radiant heating system is proposed in this paper. The system applies a 3 L thermal partition roof which applies the solar capillary roof radiation heating system,and sets up a test bench for the solar capillary radiant heating system. The heat load of building was simulated by Energy Plus,and the area of the collector was determined. The load changes of the 3 L heat partition roof and the ordinary roof laboratory were compared. The heat storage process,the heat release process and the electric auxiliary heating process were analyzed. The results show that the thermal load of the laboratory with 3 L thermal partition is significantly reduced,and the average thermal load is lower than that of the common roof 0. 521 k W. The system is safe and stable under low load buildings,and the indoor temperature is stable at around 19 C. The heat storage efficiency of the water tank is 22. 2%,and the electric auxiliary heating efficiency can reach 95%.
