| 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 UL t, ube . = 0 395 W/（m2
·℃）meets the requirements of the national standard GB/T 17049 and the average heat loss coefficient of
the system connector is UL c, on . = 1 453 ；but the average heat loss coefficient of the water storage tank Heat loss coefficient
is UL k ,tan . = 38 75 W/（m2
·℃）. 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. |
