摘　　要：为评定太阳能热水系统的性能,通过时间继电器实现太阳能热水系统间歇式循环,根据热平衡原理,进行太阳能热水系统热损系数实验研究。结果表明:全玻璃真空太阳集热管的平均热损系数∪L,tube=0.395W/(m^(2)·℃),满足国家标准GB/T 17049全玻璃真空太阳集热管的平均热损系数ULT≤0.90 W/(m2·℃)的要求,系统连接器的平均热损系数∪L,com=1.453,但贮水箱的平均热损系数∪L,tank=38.75W/(m^(2)·℃)。所以提高贮水箱的保温材料的性能是提高太阳能热水系统性能的关键。In order to evaluate the performance of the solar water heating system,the intermittent circulation of the solar water heating system is realized through the time relay,and the heat loss coefficient of the solar water heating system is experimentally studied according to the principle of heat balance.The results show that the average heat loss coefficient of the all-glass vacuum solar collector tube ∪L,tube=0.395W/(m^(2)·℃)meets the requirements of the national standard GB/T 17049 and the average heat loss coefficient of the system connector is ∪L,com=1.453;but the average heat loss coefficient of the water storage tank Heat loss coefficient is ∪L,tank=38.75W/(m^(2)·℃).Therefore,improving the performance of the thermal insulation material of the water storage tank is the key to improving the performance of the solar water heating system.
