Abstract

As the most mature kind of solar heat utilization technology, solar hot water system has been widely used and popularized. In this paper, the evacuated tube collector and the flat-plate collector are used as the research object. The two kinds of collector are most used, while the proportion of use at home and abroad is quite different. The heat collecting efficiency of the two kinds of heat collector is compared by the simulation method. The results show that the annual average heat efficiency of the evacuated tube solar water heating system is 42.9%, which is lower than that of the flat-plate solar hot water hot water system by 47.1%. In the whole year, the heat efficiency of the two sets was the largest in August, and the lowest in December. The reason is that the outdoor temperature has great influence on the heat collecting efficiency of the flat-plate solar collector, and the lower the ambient temperature, the lower the heat collecting efficiency. The evacuated tube collector has better thermal insulation performance and is less affected by the environment.
