为分析太阳能毛细管低温供暖系统在我国中部地区的运行特性,在淮南地区冬季气象条件的基础上对其进行了试验研究和理论分析.结果显示:太阳集热器具有良好的集热性能,典型日全天平均集热功率为3.49 kW,平均集热效率为32.36%.毛细管供暖系统在多数时间具有较好的运行条件,且供热性能良好,在典型日平均供热功率为1.54 kW,单位面积的供热功率为50.91 W/m2.毛细管供暖房间的温度较高,室内温度分布较均匀,全天室内平均温度为16.95 ℃,较室外和未供暖房间的平均温度分别提高10.72 ℃和10.52 ℃,室内具有较好的热舒适性.%In order to analyze the operation characteristics of the solar capillary low-temperature radiant heating system in the central region of China,experiment research and theoretical analysis were carried out on it based on the winter meteorological conditions of Huainan region. The results show that the solar heat collector has good heat collection performance,its average heat collection power and average heat collection efficiency on a typical day are 3.49 kW and 32.36%,respectively. The capillary heating system has better operating conditions and good heating performance in most of the time. On a typical day,its average heating power is 1.54 kW and its heating power per unit area is 50.91 W/m2. The room with capillary heating has a higher indoor temperature,and the indoor temperature distribution is relatively uniform. The average temperature of the room with capillary heating on the whole day is 16.95 ℃,10.72 ℃ and 10.52 ℃ higher than the outdoor air temperature and the average temperature of the room without heating,respectively. Therefore,the room with capillary heating has good indoor thermal comfort.
